  • Dimagi Naxal frames the mind as a security question

    Why in the News

    The Prime Minister’s Independence Day address named the dimagi Naxal, the intellectual Naxal, as a target of the state’s response to Left Wing Extremism (LWE). The address is defended as doing what Indian political discourse had avoided for four decades. The war against Naxalism had been measured in body counts, arms recoveries and district maps turning from red to green, and the architecture of ideas behind the insurgency was rarely confronted. The claim now advanced is that naming the ideological network forces a final battle on the deadliest terror threat to have plagued India. What that opens is a contest over whether a state can move against an ideology without moving against protected speech.

    What does the term dimagi Naxal name?

    1. The ideological support network rather than the armed cadre: The term identifies those who supply the intellectual and organisational scaffolding of the insurgency instead of carrying weapons for it.
    2. Why the coinage matters: Naming that layer shifts the counter insurgency target from territory held to ideas circulated, which no previous formulation did.
    3. Where it was used: The formulation was made from the Red Fort on Independence Day, which places it in the government’s highest profile annual statement of priorities.

    Why does the argument treat Naxalism as an ideology before a militia?

    1. The founding case: Naxalism was always an ideology before it was a militia, and the ideologue of Naxalbari theorised, organised and incited others towards armed revolution rather than acting out of personal deprivation.
    2. The social origin of the leadership: Naxal leadership across generations has been drawn from comfortable, often landed or urban intellectual backgrounds.
    3. The stated political objective: Naxals seek to overthrow the Republic of India along with its bourgeois constitution and to establish a communist state. That state is to liquidate class enemies by armed revolution.
    4. The view of the Indian state itself: Underground cadre, overground members and sympathisers hold that India is an artificial and illegitimate entity denying the right of self determination to different nationalities and working at the behest of international capital.

    What did the shift to urban expansion after 2009 change?

    1. The decision and its trigger: After Operation Green Hunt in 2009, Maoists decided to expand aggressively in urban centres and to hide in plain sight.
    2. The cover adopted: Cadre positioned themselves as human rights activists, university professors, journalists and even corporate employees.
    3. The functions assigned: The stated aims are to act as couriers, to provide safe houses for cadres of banned outfits, to stall action against terror groups, to wage an ideological war on the Indian state and to promote anarchy.
    4. The vocabulary used: Propaganda is packaged in acceptable terminology such as human rights, Dalit assertion, farmer issues and individual rights, with the ostensible aim of justice for the marginalised.
    5. What is not stated publicly: The theoretical framework behind that vocabulary associates freedom from hunger and poverty with the balkanisation of India, which makes it a messianic cult in the form of a secular ideology.

    Why did the ecosystem’s attack shift to development itself?

    1. The doctrine that worked: The government’s counter Naxal doctrine has rested on a triad of security, rehabilitation and development.
    2. The response it provoked: Because the doctrine worked on the ground, the Naxal intellectual ecosystem shifted its attack to development itself.
    3. What is now opposed: Nuclear power projects, agricultural modernisation programmes and infrastructure corridors have been opposed by a recurring cast of civil society groups.
    4. The stated basis of the objection: The objection advanced is not a specific local grievance or a flaw in the project but the writ of the Indian state in that territory.

    What does the movement’s own history suggest about resurgence?

    1. The first wave and its collapse: The first wave of Naxalism was crushed by the mid 1970s.
    2. The interval before its return: It resurfaced two decades later, which shows that suppression of the armed layer alone does not settle the question.
    3. The peak of the second wave: By the mid 2000s nearly a third of the country’s territory lay in the Red Corridor.

    How has the mode of ideological transmission changed?

    1. The old method: Ideologues had to organise physically, travel to villages, print pamphlets and hold clandestine meetings.
    2. The new method: Their successors use smartphones and build a following on Instagram, YouTube and X by monetising a persona built around resistance.
    3. What has and has not changed: The medium has changed and the incitement is more diffuse, and the function is unchanged, which is manufacturing moral cover for anti state violence and instability.
    4. Why participation has widened: Others join for the allure of resistance as a cultural posture or for the profit that anti establishment content generates, without following where the argument leads.

    Can the state contest an ideology without policing lawful dissent?

    1. The stake as the argument puts it: If the Naxals succeed there will be no freedom or liberty, no police but a party militia, no rule of law or courts but kangaroo courts, and intellectuals and professors sent to labour camps.
    2. Why bluntness is defended: People must know what the ideology stands for and the consequences that follow if it prevails.
    3. The asymmetry that closes the argument: A government can be voted out at the next election, and a state that collapses cannot be voted back.
    4. The unresolved edge: The categories the formulation names are professors, journalists and activists, so the test of the doctrine is whether it distinguishes material support for a banned organisation from lawful advocacy that the state finds inconvenient.

    Challenges to the counter Naxal doctrine

    1. A security vacuum follows the withdrawal of central forces: Handing territory back to thin State police forces creates gaps that splinter groups and criminal networks occupy. Eg. Areas cleared in earlier operations in the 1970s were reoccupied two decades later. Fix. Convert forward operating bases into permanent State police stations with local recruitment before central armed police forces are drawn down.
    2. Former cadre turn to organised crime: An insurgency deprived of ideology retains its weapons, terrain knowledge and extortion networks. Eg. Maoist financing in Jharkhand and Chhattisgarh already ran on levies from contractors and transporters. Fix. Tie surrender and rehabilitation payments to verified livelihood placement over several years rather than to a one time cash grant.
    3. Absentee administration in the cleared districts: Security gains do not hold where teachers, doctors and revenue officials do not report to their posted stations. Eg. Interior blocks of Bastar have run on deputation and vacancy for years. Fix. Pay a hardship differential and fix minimum tenure norms so that posting to an interior block is a career step rather than a punishment.
    4. Rejected forest rights claims reopen the original grievance: Land alienation is the grievance the insurgency was built on, and the statutory remedy is under used. Eg. Community Forest Rights claims face high rejection rates in the same districts that were worst affected. Fix. Audit rejected claims at the district level under the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 and record reasons for each rejection in writing.
    5. Peace attracts the extraction that caused the conflict: A district declared safe becomes available for mining and industrial investment, which brings displacement back. Eg. Iron ore and bauxite belts overlap almost exactly with the former Red Corridor. Fix. Require Gram Sabha consent under the Panchayats (Extension to the Scheduled Areas) Act, 1996 and transparent use of District Mineral Foundation funds before new leases are cleared.
    6. Prosecuting the overground network is evidentially hard: Cases built on association rather than on an act collapse in court and produce long undertrial detention in the interim. Eg. Several urban prosecutions under anti terror law have run for years without trial beginning. Fix. Require sanctioning authorities to record specific evidence of material support before charges are framed, and impose statutory timelines on trial commencement.

    Conclusion

    The formulation moves counter insurgency from a territorial contest to a contest over ideas, at the point where the armed movement has been declared defeated and its support network has not. The government’s own record shows that suppression of the armed layer without settling the grievance produced a second wave two decades later, which is the case for confronting the ideology rather than only the militia. What remains unresolved is the line between the material support network the state may lawfully dismantle and the criticism a democracy is obliged to tolerate, and that line will be drawn by courts rather than by speeches.

  • Saving faces: Use of facial recognition equipment at protest site is worrisome

    Why in the News

    The Delhi Police has told the Supreme Court that it deployed a facial recognition system at the site of the Cockroach Janta Party protests, along with a mobile surveillance van, a command and control vehicle, smart spectacles and drones. The disclosure came in the same proceeding. In that proceeding the force has continued to deny using excessive force or manhandling demonstrators, contrary to the protestors’ own testimonies. India is therefore normalising the technical ability to subject political gatherings to searchable biometric surveillance. Legislation and judicial oversight have not yet settled when the state may lawfully do so. The contest is between a policing capability that is already operational and a legal framework that names no threshold, no authorising authority and no retention rule for its use.

    What is a facial recognition system?

    1. It converts a face into a searchable record: The system extracts measurable geometric features from a face image and stores them as a numeric template that can be matched against other templates.
    2. Two distinct operations, two different risk profiles: Verification matches one face against one claimed identity. Identification matches one face against an entire database, and only the second turns a crowd into a search.
    3. Real time capture removes the choice to participate anonymously: Cameras enabled with Artificial Intelligence (AI) scan faces as people move and run matches against a database without any interaction with the person scanned.

    What surveillance equipment did the police say it had deployed?

    1. A facial recognition system with AI enabled cameras: These scanned faces in real time against a database. The demonstration was under way at the time.
    2. A mobile surveillance van: A vehicle mounted capture platform able to move with the crowd rather than covering a fixed field.
    3. A command and control vehicle: The on site node where feeds from the various capture devices were aggregated and acted on.
    4. Smart spectacles: Wearable devices used to identify individuals on the move, which extends identification beyond fixed and vehicle mounted cameras.
    5. Drones and videographers: Aerial and handheld recording covering the site from angles the ground cameras did not reach.
    6. Private contractors hold two of these systems: The van and the spectacles have been tied to private contractors on terms that have never been disclosed, so a commercial entity sits inside the capture chain on an unknown mandate.

    What did the police not disclose?

    1. Whether every face in range was processed: The force has not addressed whether actual biometric processing occurred for every individual within the range of the cameras, which is the difference between targeted identification and mass capture.
    2. Where discarded images went: Images from checks that produced no match were open to copying in the interim, and the force has not said whether any copy survives.

    Which laws currently govern facial recognition, and what do they leave open?

    1. No statute governs the technology: There is no law in force that regulates the use of facial recognition systems by the state, so deployment rests on executive decision alone.
    2. The data protection law is not yet operative on this point: The Digital Personal Data Protection Act, 2023, whose data processing obligations are not yet in force, still makes broad exemptions for state agencies.
    3. The existing police database is purpose limited: The Automated Facial Recognition System of the National Crime Records Bureau is meant for identifying criminals and unidentified bodies, not for scanning an assembly.
    4. The 2022 statute widened records, not subjects: The Criminal Procedure (Identification) Act, 2022 expanded the set of records the police may collect, but only from specified persons rather than from the public at large.
    5. The gap is the crowd: Every one of these instruments operates against identified groups of people, and none of them authorises indiscriminate capture of everyone present at a location.

    Can mass biometric capture at a protest survive the proportionality test?

    1. The state carries the burden: Interference with the right to privacy must clear a well established proportionality test, and the burden of establishing each limb sits on the state.
    2. The first limb already fails on the facts: The existence of a legitimate objective is hard to establish for facial recognition used en masse, because the technology is indiscriminate at the point of capture and cannot be aimed at a suspect.
    3. A less restrictive alternative exists: Conventional policing achieves the same objective of maintaining order and identifying offenders without capturing the biometrics of every person present.
    4. Constitutional validity is not the only test: Even leaving aside the constitutionality of the police action, a capability deployed without a governing standard sets the precedent for the next deployment.

    How does biometric surveillance affect the right to protest?

    1. The deterrent operates before any legal restriction: The chilling effect on potential participants curtails the right to protest without any order prohibiting the protest.
    2. Anonymity is part of the freedom: Assembly has historically carried the assurance that presence in a crowd is not the same as being recorded as an individual participant.
    3. The cost falls on people with the most to lose: Government employees, students facing institutional discipline and people in precarious work self select out once presence becomes a permanent identified record.
    4. The chill is unfalsifiable: Nobody counts the people who stayed home, so the harm never appears in the record a court would examine.

    What remains unanswered before this use can be justified?

    1. The access controls: It is unknown which officers, agencies or contractor personnel could query the captured images and against which databases.
    2. The authorising legal provisions: The provisions relied on to authorise the major decisions, including the decision to scan an entire assembly, have not been identified.
    3. The false positive rate: The expected error rate of the system has not been stated, and a false match at a protest site produces detention of an innocent person on machine evidence.

    Challenges to the regulation of facial recognition technology in India

    1. Deployment has run far ahead of legislation: State and city police forces have procured systems under general policing powers rather than under any enabling statute. Eg. Several State police departments and airports adopted facial recognition without a dedicated legal framework in place. Fix. Enact a facial recognition statute prescribing permitted purposes, a judicial or independent authorisation requirement, and a fixed retention period.
    2. The data protection statute exempts the principal user: Broad exemptions for state agencies mean the very actor conducting mass capture falls outside the consent and purpose limitation architecture. Eg. The Justice B N Srikrishna Committee had recommended narrow and specified exemptions rather than open ended ones on grounds of sovereignty and public order. Fix. Replace the blanket agency exemption with a case by case exemption that must be notified with reasons and laid before Parliament.
    3. Accuracy is unequal across populations: Error rates for facial recognition are consistently higher for darker skinned faces, women and younger subjects, so the burden of false matches is not evenly distributed. Eg. Independent testing of commercial systems has repeatedly found the highest error rates for darker skinned women. Fix. Mandate published accuracy testing disaggregated by skin tone, sex and age before any system is procured for policing use.
    4. Private contractors sit inside the state’s capture chain: Outsourcing capture hardware and processing places biometric data with entities that are not accountable through public law remedies. Eg. Police facial recognition deployments in several States run on vendor supplied platforms whose procurement contracts are not in the public domain. Fix. Require every surveillance procurement contract to be published with its data handling clauses, and make the contractor a joint respondent in any privacy proceeding.
    5. There is no oversight body with jurisdiction: No standing authority audits police biometric systems, so no institution can verify retention, deletion or match logs after the event. Eg. Agencies conducting interception under existing law are reviewed only by an internal executive review committee. Fix. Establish a statutory surveillance oversight commission with power to inspect match logs and order deletion.
    6. Function creep is the default trajectory: A database built for one purpose is progressively opened to others once the infrastructure exists. Eg. Facial recognition adopted for airport boarding convenience has been proposed for wider identity verification uses. Fix. Write a statutory bar on cross purpose querying, with each authorised purpose requiring a separate legislative amendment.

    Conclusion

    The disclosure establishes that the capability to convert a political gathering into a searchable biometric record is already deployed, contracted out in part, and operating without a statute that says when it may be used. The proportionality test, on the facts available, is not close: the technology captures indiscriminately, a less restrictive alternative exists, and the state has not identified the provision that authorised the decision. Until Parliament enacts a facial recognition law with a stated purpose, an authorising authority, a retention limit and published accuracy standards, each deployment simply widens the precedent for the next one.

  • Pakistan factor: Why West Asia war hurt Indian airlines more than foreign ones

    Why in the News

    International air passenger traffic to and from India fell 9.1 per cent year on year in April to June 2026, to 1.72 crore, after the West Asia conflict closed large parts of Gulf airspace. The decline was driven entirely by Indian carriers, whose combined international traffic fell 26.6 per cent. Foreign airlines carried 6 per cent more passengers than a year earlier. India has barred its own carriers from Pakistani airspace since late April 2025, and Pakistan’s reciprocal closure applies only to them. The result is that a shared shock produced an asymmetric outcome, transferring market share on India’s own international routes to airlines that could still fly the short way west.

    How does an airspace ban change an airline’s operating economics?

    1. The right involved: A carrier overflies a third country under the International Air Services Transit Agreement of 1944 or under a bilateral permission, and either can be withdrawn at short notice.
    2. The detour cost: A closure forces a longer track, which adds block hours, fuel burn and crew duty time to every affected departure.
    3. The payload penalty: A longer sector makes the aircraft trade revenue payload for fuel, or forces a technical stop, and either outcome erodes the margin on the route.

    What does the passenger data show?

    1. Total volume: Total international air passenger volume to and from India fell 9.1 per cent year on year in April to June, from 1,89,12,598 to 1,72,00,140, in an analysis of Directorate General of Civil Aviation (DGCA) data.
    2. Indian carriers: Their combined international passenger numbers fell 26.6 per cent, from 87,34,038 to 64,14,896.
    3. Foreign carriers: Their cumulative passenger base rose 6 per cent, from 1,01,78,560 to 1,07,85,244.
    4. Market share shift: Foreign operators expanded their share of India’s international traffic to 62.7 per cent from 53.8 per cent, and domestic carriers dropped to 37.3 per cent from 46.2 per cent.

    Why did the loss fall on Indian carriers alone?

    1. Their biggest market closed: Flights to the United Arab Emirates and other West Asian markets, the largest destinations for Indian airlines, were heavily curtailed.
    2. The damage spread beyond West Asia: Indian carriers were forced to cut flights to destinations well outside the region, under war related financial pressure and the standing ban on flying over Pakistan since late April 2025.
    3. The route economics broke first: Air India and IndiGo curtailed their west bound network because the unavailability of Pakistani airspace made some services financially and operationally unviable to run.
    4. The pressure predated the war: Both leading carriers were already taking longer routes and adding refuelling halts on west bound services from their Delhi hub before the conflict began in late February, and some routes had been suspended outright.

    How did foreign carriers turn the same shock into share?

    1. They kept the short way west: Foreign carriers faced the same surging jet fuel prices, and many held one decisive advantage in the continued availability of Pakistani airspace.
    2. Spare capacity was redeployed: Once the war began, carriers from Europe and other regions west of India increased operations to and from the country using aircraft freed by their own curtailed West Asia flying.

    Which Indian airlines lost most?

    1. IndiGo: Remained the largest Indian carrier on international routes with a 15.4 per cent decline to 33.4 lakh international flyers, and an international market share slipping to 19.4 per cent from 20.9 per cent.
    2. Air India: Fell 27.2 per cent to 19.3 lakh passengers, with its international market share contracting to 11.2 per cent from 14 per cent.
    3. Air India Express: Its footfall halved to 8.34 lakh, since its network is highly concentrated in West Asia, and its share fell to 4.8 per cent from 8.9 per cent.
    4. The Air India group: Combined international traffic fell 36.3 per cent year on year to 27.61 lakh in the quarter.
    5. SpiceJet: Recorded the sharpest percentage fall at 56 per cent, to 1.38 lakh international flyers, with share contracting to 0.8 per cent from 1.7 per cent.
    6. Akasa Air: The only Indian airline to register higher international passenger numbers, growing on a low base through an expanding fleet.

    Challenges to Indian carriers on international routes

    1. Gulf hubs capture the through fare: Foreign carriers connect Indian cities to the West over their own hubs and book the full journey revenue. Eg. Emirates, Qatar Airways and Etihad carry a large share of India to Europe and North America traffic over Dubai, Doha and Abu Dhabi. Fix. Build a domestic transfer hub with matched arrival and departure banks, and price transfer charges to reward connecting traffic.
    2. Wide body fleet shortage: Non stop long haul flying needs aircraft Indian carriers do not have in sufficient number. Eg. Air India’s wide body cabin refit programme has run behind schedule because of queues at overseas retrofit facilities. Fix. Expand domestic maintenance, repair and overhaul capacity so heavy checks and retrofits are not queued abroad.
    3. Fuel taxation: Aviation turbine fuel sits outside the goods and services tax and carries high state value added tax, so the largest cost line is not creditable. Eg. Fuel accounts for about 40 per cent of an Indian airline’s operating cost. Fix. Bring aviation turbine fuel under the goods and services tax with input tax credit for carriers.
    4. Ageing bilateral entitlements: Traffic rights negotiated years ago cap Indian carriers in some markets. The same rights leave foreign carriers entitlements they can deploy at short notice. Eg. India’s bilateral seat entitlement with the United Arab Emirates has been unchanged for over a decade. Fix. Renegotiate bilaterals with entitlement tied to actual utilisation and reciprocal hub access.
    5. Financing and leasing sit offshore: Most aircraft are leased through foreign lessors, so rentals and repossession law lie outside Indian jurisdiction. Eg. The aircraft leasing framework at Gujarat International Finance Tec-City (GIFT City) remains small relative to the fleet on lease. Fix. Deepen the domestic leasing regime and fully operationalise the Protection of Interests in Aircraft Objects Act, 2025 giving effect to the Cape Town Convention.

    Conclusion

    The quarter’s traffic decline was distributed by airspace access rather than by exposure to the war, so Indian carriers absorbed the whole of a shock both sides faced. The share transferred to foreign operators is not automatically reversible, since network presence and slot use tend to persist once established. Recovery depends on the reopening of Pakistani airspace to Indian carriers and on the restoration of West Asian capacity, neither of which is within the sector’s control.

  • Indigenous N-reactors top pick for companies in nuclear power expansion

    Why in the News

    The indigenous Pressurised Heavy Water Reactor (PHWR) is emerging as the preferred technology for new entrants into India’s civil nuclear power sector, as the tightly regulated strategic sector opens to private players. Representatives of the National Thermal Power Corporation (NTPC), Adani Atomic Energy and Jindal Steel said at a panel discussion at the BloombergNEF Summit in New Delhi that the existing 700 megawatt electric (MWe) PHWR is the right starting point, given established design standards, a mature domestic supply chain and an existing ecosystem of vendors. The discussion followed the release of the draft rules under the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India Act, 2025 (SHANTI Act, 2025), about a week earlier. The choice is revealing: entrants are picking the reactor with the least regulatory and supply risk rather than the one that scales fastest, and that reactor alone cannot deliver the 100 gigawatt electric target set for 2047.

    What is a Pressurised Heavy Water Reactor?

    1. Design: A pressurised heavy water reactor uses heavy water as both moderator and coolant, which lets it run on natural uranium without any enrichment step.
    2. Why it suited India: Natural uranium fuelling matched a country with limited enrichment capacity that long stood outside international fuel supply arrangements.
    3. Place in the programme: It is Stage 1 of the three stage nuclear programme designed by Homi Bhabha, producing plutonium 239 as a by product for the fast breeder stage that follows.
    4. The Indian standard unit: The 700 MWe variant is the largest indigenous design in the series.

    What is a Small Modular Reactor?

    1. Definition: A small modular reactor (SMR) is an advanced reactor of up to 300 MWe, built as factory made modules and transported to site for assembly.
    2. Use case: The smaller unit size suits captive industrial power and the replacement of retiring coal units on existing sites.

    Why are private entrants choosing the 700 MWe PHWR?

    1. Design certainty: The 700 MWe design is standard, approved, operational and already carries regulatory clearance, in the assessment of the business head of Adani Atomic Energy.
    2. Supply chain depth: The supply chain for that design in India is almost fully indigenised, at 90 per cent to 95 per cent.
    3. What the sector is short of: The two major constraints named for the sector are the availability of a robust supply chain and the lack of standardised reactor designs, and the 700 MWe unit is the one design that resolves both.
    4. A second entrant agrees: Jindal Steel plans to go with 700 MWe PHWRs in its initial phase for the same reason, moving to other technologies in later phases as clarity emerges on supply chains, regulatory approvals and standardisation.

    What capacity are the new entrants targeting?

    1. The national target: India aims to scale domestic civil nuclear capacity to 100 gigawatt electric (GWe) by 2047.
    2. Corporate targets: NTPC’s capacity target is 30 GWe, the Adani group’s is 10 GWe, and Jindal Steel’s is 18 GWe in the coming years.

    What has opened the sector to private entrants?

    1. Statutory replacement: The SHANTI Act, 2025 supersedes the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010.
    2. End of the state monopoly: It permits private and foreign firms to build, own and operate reactors, which no earlier law allowed.
    3. Regulator strengthened: It gives the Atomic Energy Regulatory Board independent statutory status for safety oversight.
    4. Liability rewritten: It removes statutory supplier liability and sets tiered damage caps, with a Nuclear Damage Claims Commission to adjudicate compensation after an incident.
    5. What the Centre keeps: Enrichment, reprocessing and uranium and thorium exploration remain with the Union government.
    6. What the draft rules cover: The rules released in August 2026 set out the framework for private participation, captive generation, licensing, safety oversight and nuclear liability.

    Why will the PHWR alone not deliver 100 GWe?

    1. The stated limit: PHWRs alone will not be sufficient to reach 100 GWe by 2047, in the assessment of the Adani Atomic Energy business head.
    2. The intended sequence: Deploy 700 MWe PHWRs in fleet mode first, follow with pressurised water reactors (PWRs), and bring in small modular reactors at a later point.
    3. Where foreign designs fit: Foreign reactor technologies and SMRs are expected to play a role only at a later stage, once the sector matures.
    4. The phasing is deliberate: Later phases are contingent on clarity around supply chains, regulatory approvals and design standardisation, not on a fixed date.

    What will decide whether imported designs work in India?

    1. Localisation is the condition: Global reactor technologies, including PWRs and SMRs, would need to maximise localisation in India to stay commercially viable.
    2. Cost sets the ceiling: Cost matters a great deal in the Indian market, and any technology has to reach a price the buyer of the electricity will commit to.
    3. The buyer decides: For a project to make commercial sense the consumer has to accept the tariff, which puts affordability ahead of technology preference in the selection.

    Challenges to India’s 100 GWe nuclear target

    1. The heavy component vendor base is shallow: Only a handful of Indian firms can forge and supply large reactor components, so a fleet order queues behind them. Eg. Larsen and Toubro and Bharat Heavy Electricals supply most large forgings and steam generators for the domestic programme. Fix. Qualify a second tier of suppliers through advance purchase commitments tied to the sanctioned fleet order book.
    2. No certified standard design outside the heavy water line: A project without a frozen design spends years in negotiation before construction. Eg. The Jaitapur project with the European Pressurised Reactor has been under negotiation since 2010 without first pour of concrete. Fix. Certify one design per technology class through the regulator before any commercial order is placed.
    3. Tariff acceptance by distribution utilities: Nuclear power has to clear the price a distribution company will sign a purchase agreement at. Eg. Around 42 gigawatts of renewable capacity currently sits without a power purchase agreement on price grounds. Fix. Create a separate payment for firm, dispatchable low carbon power so the grid pays for reliability rather than for energy alone.
    4. Insurance capacity is thin: Liability caps do not create the underwriting capacity a reactor needs. Eg. The India Nuclear Insurance Pool formed in 2015 carries a capacity of ₹1,500 crore. Fix. Expand the pool with reinsurance from global nuclear insurance pools, now that supplier liability has been removed.
    5. Licensed operator manpower: A fleet of reactors needs certified control room staff that only one training system currently produces. Eg. Operator training runs almost entirely through the Department of Atomic Energy’s own training schools. Fix. Accredit private and university training programmes against a regulator certified curriculum and examination.

    Conclusion

    Private entry into nuclear power has reached the point where entrants are naming capacity targets and choosing a reactor, and all three have chosen the indigenous 700 MWe pressurised heavy water reactor over imported designs. The regulatory framework is at the draft rules stage under the SHANTI Act, 2025, released by the Department of Atomic Energy, with comments closing on 4 September 2026. Whether the 100 GWe target is reachable turns on the technologies after the first fleet, and on whether foreign designs localise enough to reach a tariff a distribution utility will sign.

  • The Silver Bullet: Why everyone loves a Metro

    Why in the News

    Around 200 residents of Greater Noida West tied ropes to the last Metro pillar at the Sector 71 intersection in April and pulled, in a protest organised by the Noida Extension Flat Owners Welfare Association to demand a Metro line for an area it calls underserved by public transport. Days earlier the Central government had rejected the proposal for the Noida to Greater Noida West Metro corridor. Meerut became the latest city to get a Metro in February 2026, with an interchange to the Regional Rapid Transit System (RRTS), India’s first semi high speed intercity rail service. The tension the two scenes expose is that demand for a Metro is now generated by politics and property. The ridership, fares and feeder transport that would justify one are generated by city planning that has not happened.

    What is the Metro Rail Policy, 2017?

    1. Purpose: It sets the conditions the Union government applies before it will approve or fund a metro rail project proposed by a state.
    2. Alternatives test: A state must evaluate cheaper options, including buses, bus rapid transit and trams, before committing to a metro, because metro rail is the costliest urban transport mode to build.
    3. Viability emphasis: It places greater weight on the financial viability of a project than earlier practice did.
    4. Appraisal method: It requires appraisal through economic and social cost benefit analysis, treating urban rail as a public project that delivers a public good.

    What is a Detailed Project Report?

    1. Definition: A Detailed Project Report (DPR) is the blueprint that lays out a metro project’s design, its costs, its ridership projection and its financial viability.
    2. Function: It is the document the Union government appraises the proposal against, and the document later audits measure actual performance against.

    How large has India’s Metro network become?

    1. Fourfold growth: The network has gone from around 250 km a decade ago to more than 1,100 km across 26 megacities and Tier 2 cities, with another 900 km under construction.
    2. Rate of sanction: The government is sanctioning 6 km of Metro lines every month.
    3. A young network: More than three fourths of the current network was conceived, constructed and operationalised less than 10 years ago.
    4. Aggregate ridership: Daily ridership across the country has crossed the 1 crore mark and is expected to exceed 1.25 crore in a year or two.
    5. The capacity argument: Some Delhi Metro corridors handle more than 50,000 passengers in the peak hour in the peak direction, and the Ministry of Housing and Urban Affairs calculated in January 2024 that serving that demand by bus would need 715 buses an hour in one direction, roughly one every five seconds.

    Which cities run a Metro, and how do the systems compare?

    1. Kolkata, 1984: The country’s first Metro system, and the only one run by the Indian Railways.
    2. Delhi, 2002: The Delhi Metro Rail Corporation (DMRC) now runs 416 km with an average daily ridership of about 64 lakh, the largest network in the country.
    3. Bengaluru, 2011: Namma Metro runs 96 km, the second largest operating system outside the National Capital Region.
    4. Meerut, 2026: The newest system runs 23 km with an average daily ridership of about 1 lakh, a figure that includes RRTS ridership at the shared station.
    5. The rest of the map: Gurgaon opened in 2013, Chennai in 2015, Hyderabad, Kochi and Lucknow in 2017, Ahmedabad and Nagpur in 2019, Noida in 2019, Kanpur in 2021, Pune in 2022, Navi Mumbai in 2023, Agra in 2024, and Bhopal, Indore and Patna in 2025.

    Why does every city want a Metro?

    1. Density of unserved demand: The Greater Noida West association puts around 10 lakh residents and at least 80 societies in the area it says has no rapid transit.
    2. A visible proof of development: Local administrations and politicians want a Metro network in their constituency to demonstrate development, in the assessment of a rail and Metro consultant and former country head of Bombardier Transportation India.
    3. It has entered the manifesto: In five of the last six state elections, in West Bengal, Tamil Nadu, Kerala, Assam, Bihar and Delhi, at least one major party promised Metro projects, their expansion, or fare concessions.
    4. Party specific claims: The Dravida Munnetra Kazhagam (DMK) claimed credit for bringing Metro Rail service to Chennai. The Bharatiya Janata Party (BJP) in Bihar promised Metro trains in Muzaffarpur, Gaya, Bhagalpur and Darbhanga.

    Why does ridership fall so far short of projection?

    1. The systemic gap: Most Metro systems are meeting just 25 per cent to 35 per cent of their projected ridership, in a 2023 analysis by professors at the Indian Institute of Technology Delhi. Delhi at 47 per cent and Kolkata at 38 per cent fared relatively better.
    2. Bengaluru: Namma Metro was projected to carry 18.54 lakh passengers a day by 2020-21, as recorded by the Standing Committee on Housing and Urban Affairs in a 2022 report, and carries around 10 lakh in 2026.
    3. Kochi: The 28 km system should have reached 5.39 lakh daily riders by now under its DPR and averages around a lakh, with the projection since revised to 1.5 lakh a day, a target the operator hopes to meet in the next 10 months.
    4. Jaipur: Average daily ridership was 51,000 in the inaugural month of June 2015 and stood at 53,000 in June 2026, and the Union Cabinet approved a second phase in April for ₹13,037 crore.
    5. Nagpur: A 2022 Comptroller and Auditor General report found the New Airport station averaged 47 passengers a day over 18 months from the start of commercial operation in March 2019, against 5,474 a day envisaged in the DPR.

    Why does the Metro not fit the way Indian cities actually travel?

    1. Trip length mismatch: Research at the Transportation Research and Injury Prevention Centre finds the Metro efficient only for commutes beyond 10 km. Most city commutes are shorter than 5 km, and even in Delhi only 15 per cent of trips exceed 10 km and 7 per cent exceed 20 km.
    2. What the short trip costs: For a short journey a passenger has to add the time taken to reach the station, the stops en route and the last mile at the other end, which other modes avoid.
    3. Alignments miss the destinations: The Ahmedabad Metro does not serve SG Highway, the commercial hub holding the city’s offices and malls, nor the university area.
    4. Last mile decides the mode: A commuter with neither home nor office near a station finds public transport more expensive than a personal scooter or a hired cab.

    What in the city’s own design keeps people out of the Metro?

    1. Driving is not priced: Low or non existent parking charges make private vehicle use cheaper than it should be, and poor footpaths make the walk to a station unattractive.
    2. Feeder networks are not built: Last mile connections and integration across modes rarely materialise once a line opens, in the assessment of a Metro consultant, so a passenger reaches the station on his own or not at all.
    3. The city is not shaped to feed the line: The Mumbai Metro struggles to perform because the city was not planned in a way that channels trips into it, in the assessment of a transportation researcher at the Indian Institute of Management Ahmedabad.

    Why are fares high, and who does that exclude?

    1. Fares follow the viability test: Metros are obliged to keep fares high mainly to make both ends meet, a consequence the first Managing Director of DMRC attributes to the emphasis the 2017 policy places on financial viability.
    2. Who is priced out: High fares keep out a section of the population. That section turns to less dependable but cheaper public transport.
    3. The pricing only works on some trips: A Lucknow resident finds the 23 km city Metro worth ₹70 for an airport trip against ₹400 by auto, and uses an auto or two wheeler for every daily commute.

    What do other countries’ networks show about where India stands?

    1. Absolute scale: India at 1,100 km is set to overtake the 1,400 km subway system of the United States, and remains far behind China’s 10,000 km network.
    2. Financing and operating culture: The Delhi Metro was funded by the Japan International Cooperation Agency through flexible loans. It adopted a Japanese operating ethic centred on punctuality and queue discipline, giving Indian cities a template for dignified urban transit.
    3. When to start planning: The developed country model is to begin planning a Metro when a city’s population crosses 10 lakh and to have the system running by the time it reaches 20 lakh, on which basis the Metros in Patna, Jaipur, Bhopal and Lucknow are justified.
    4. Networks are built over generations: Tokyo, Hong Kong and Paris were not built in a day, so a large infrastructure investment has to begin well ahead of the demand it will eventually serve.
    5. Optimism is not an Indian trait: Large infrastructure projects globally overestimate initial projections and underestimate costs, and the shortfall is routinely overlooked on the ground of greater public good.

    Who decides whether a city needs a Metro?

    1. The decision precedes the study: The process typically begins with a state government deciding it wants a Metro, an idea that crystallises quickly and often before any formal study is done.
    2. The assessor is the beneficiary: State governments create a Metro authority and then ask that same body, which stands to run the project, to assess whether the city should build a Metro at all.
    3. What that produced in Jaipur: A 2017 Comptroller and Auditor General report found the city, with a population of 2.3 million, was not eligible for a metro rail project, and concluded that defective planning and hasty decision making introduced a financially unviable Metro system in Jaipur.
    4. Accountability is thin: Queries to the Metro systems in Delhi, Lucknow, Ahmedabad, Hyderabad, Bengaluru, Nagpur, Jaipur and Chennai went unanswered.

    Is the Metro over built, or is it under fed?

    1. For some riders it is the only option: A 21 year old hospital intern living in a central Delhi slum reaches work 17 km away in Noida in 45 minutes by Metro, against a 6 am start at a bus stop to arrive at 9 am, and returns after 9 pm because the Metro feels safe.
    2. The cost of waiting is higher: It is easier and cheaper to build a Metro in a smaller city before it grows and congests, and cities that do not start now will face the situation their larger counterparts already face.
    3. The objection is to the trade off, not the mode: The problem is not that governments promote the Metro but that they do so at the cost of other public transport, so a city must still depend on a reliable road based system alongside it.
    4. The official defence: Ridership projections account for a city’s Master Plan and its future development potential, ridership is significantly influenced by network density and extent, and ridership on many DMRC lines has exceeded the projections made in their DPRs.

    Challenges to metro rail expansion in India

    1. Debt service migrates to the state budget: A corporation borrows against ridership that does not arrive, and repayment then falls on the exchequer. Eg. Kochi Metro Rail has run operating losses since 2017 and depends on continuing state support. Fix. Fund a defined share of operations from a dedicated urban transport levy on fuel and parking rather than from the farebox alone.
    2. No unified metropolitan transport authority: Bus, metro, suburban rail and para transit run as separate agencies with separate fares and no common timetable. Eg. Delhi’s Metro, cluster buses and Delhi Transport Corporation services operated for years without a single ticket. Fix. Constitute statutory Unified Metropolitan Transport Authorities with fare setting and route rationalisation powers, as the National Urban Transport Policy, 2006 envisaged.
    3. The land value the line creates is not captured: Property owners along a corridor capture the price rise that public investment produced. Eg. Land values near Delhi Metro corridors rose sharply with no betterment levy accruing to the operator. Fix. Levy a betterment charge along corridors and grant development rights over station land to the metro corporation.
    4. Fare revision is politically blocked: Costs rise annually and fares are revised only when a government is willing to absorb the reaction. Eg. Delhi Metro fares went unrevised for years after the 2017 revision despite rising energy and staff costs. Fix. Make revision automatic through an indexed formula operated by a statutory Fare Fixation Committee.
    5. Signalling and rolling stock depend on a few suppliers: Core train control technology is supplied by a small set of foreign vendors, which raises cost and lengthens delivery. Eg. Communications based train control systems on Indian metros are supplied largely by three global vendors. Fix. Use the domestic content requirement in metro procurement to qualify Indian signalling suppliers through a guaranteed order pipeline.

    Conclusion

    India is adding metro rail faster than it is adding the ridership, fares and feeder transport that would make the network work, because the demand being satisfied is political and territorial rather than a measured transport demand. Nothing in the record suggests the mode is wrong for the corridors that genuinely carry the volume, and the record does show that the appraisal deciding which corridors those are is conducted by the body that stands to build them. The unresolved question is whether appraisal will be separated from execution, and whether bus and road based transport will be funded alongside the Metro rather than after it.

    “[2014, GS3, 12.5 marks] National Urban Transport Policy emphasises on ‘moving people’ instead of ‘moving vehicles’. Discuss critically the success of the various strategies of the Government in this regard.”

  • On interest rates, can’t be both dovish & hawkish

    Why in the News

    The Monetary Policy Committee of the Reserve Bank of India (RBI) voted unanimously at its last meeting to hold the benchmark repo rate at 5.25 per cent, in a policy read as more dovish than expected. The minutes of that same meeting, released a few days ago, point the other way. Members drawn from the central bank displayed a distinct hawkishness, and the Bank’s own inflation projections imply negative real interest rates on a forward basis. The divergence is the problem: a stance described as neutral cannot be reconciled with projections that would stimulate activity, nor with a growth assessment the Bank itself calls resilient.

    What is a monetary policy stance?

    1. What it signals: The stance states the direction of the committee’s next expected move on the policy rate. That signal is separate from the rate set on the day.
    2. Accommodative: The committee signals that the next move is a cut, or that liquidity will stay supportive of demand.
    3. Neutral: The committee commits to no direction and keeps both a cut and a hike open at the following meeting.
    4. Tightening or withdrawal of accommodation: The committee signals that the next move is a hike, or the removal of surplus liquidity from the system.

    What is the real interest rate?

    1. Definition: The real interest rate is the nominal policy rate less expected inflation, so it measures what a lender actually earns once prices have risen.
    2. Why the sign matters: A negative real rate makes money cheaper than the rate at which prices are rising, which pushes households and firms toward borrowing and spending.

    What did the last policy decision signal?

    1. The stance retained: The committee kept the stance neutral alongside that hold.
    2. The tone: The policy read as more dovish than many analysts had expected at the time.
    3. The inference drawn: Analysts concluded that rate hikes were not imminent, even with inflation projected above target.

    How do the minutes of the same meeting read differently?

    1. A reversal in signal: The minutes suggest the current situation is unlikely to be maintained over the near term, and the divergence from the policy statement is striking.
    2. The internal members hardened: That hawkishness came from the members drawn from the central bank, not from the committee as a whole.
    3. How far each went: An assessment by economists at the State Bank of India reads the Governor’s minutes statement as showing an inclination toward policy tightening, records a Deputy Governor calling for a possible rate hike later in the year, and notes an Executive Director stopping just short of the same call.
    4. A different objection from outside: External members of the committee drew attention instead to the real interest rate.

    Can a neutral stance sit with negative real interest rates?

    1. The projections: The Bank has pegged inflation at 5.9 per cent in the third quarter, 5.5 per cent in the fourth quarter, and 5.3 per cent in the first quarter of the next financial year.
    2. What they imply: Against a repo rate of 5.25 per cent, those projections put real interest rates in negative territory on a forward basis.
    3. What negative real rates do: They stimulate economic activity, which is a different setting from the stance the committee has adopted.
    4. What neutral is supposed to mean: The Governor has previously stated that a neutral stance implies no support for economic activity and no support for controlling inflation.
    5. The growth assessment compounds it: The Bank describes growth as resilient, supported by domestic demand, sustained expansion in manufacturing and services activity, and robust exports, which removes the case for a stimulative real rate.

    What does the same uncertainty look like at other central banks?

    1. A shared condition: Central banks across the world are grappling with uncertainty over inflation and over the course of monetary policy.
    2. The United States: The Federal Reserve maintained interest rates in July, and the path of policy after that remains unclear.
    3. The same gap between decision and minutes: The minutes of that Federal Reserve meeting record that several participants favoured an increase of 25 basis points in the target range.

    What will decide the next move?

    1. The October meeting: By the time the committee meets next in October, there should be more clarity on agriculture and on the trajectory of inflation.
    2. The projections as the signal: The Bank’s revised inflation projections will show what it expects of underlying price pressures going forward.
    3. The consequence: Those expectations are what would produce an adjustment in the policy rate.

    Challenges to India’s flexible inflation targeting framework

    1. A headline target moved by food: Food and beverages carry close to half the weight in the Consumer Price Index, so the target responds to harvests that no policy rate can influence. Eg. Vegetable price spikes pushed headline inflation above the upper tolerance band in 2023 and 2024. Core inflation stayed subdued through the same period. Fix. Publish an explicit core inflation reference alongside the headline target, so the committee’s tolerance for supply shocks is visible in advance.
    2. An ageing consumption basket: The index in use rests on a consumption pattern captured years ago, so the measured basket drifts from what households actually buy. Eg. Services such as data, health insurance and education are underweighted relative to current household spending. Fix. Fix a statutory revision cycle for the index base year so the measure and the target are reset together.
    3. Exchange rate pressure competes with the target: Rate decisions taken for domestic prices collide with the management of capital flows. Eg. Record foreign portfolio outflows in 2025-26 forced heavy intervention to steady the rupee. Fix. State an explicit order of priority between the inflation target and exchange rate smoothing in the policy statement.
    4. No fiscal counterpart to the target: The framework binds the central bank alone, with no matching commitment on borrowing. Eg. Heavy government borrowing keeps longer tenor yields elevated regardless of where the repo rate is set. Fix. Pair each five year target reset with a stated debt to gross domestic product path under the Fiscal Responsibility and Budget Management Act, 2003.
    5. Accountability stops at a report: A sustained breach obliges a report and nothing further. Eg. The report on a target breach goes to the Central Government and is not laid before Parliament. Fix. Require the report to be tabled in Parliament with a stated corrective path and a review date.

    Conclusion

    A unanimous hold read as dovish now sits alongside minutes that record internal calls for tightening and projections that imply negative real rates. The policy statement, the stance and the projections are describing three different settings, and only one of them can be the policy. The October meeting, with clearer information on agriculture and on the inflation trajectory, is where that inconsistency has to be resolved into either a rate move or a change of stance.

    “[2023] Consider the following statements :

    Statement-I: In the post-pandemic recent past, many Central Banks worldwide had carried out interest rate hikes.

    Statement-II: Central Banks generally assume that they have the ability to counteract the rising consumer prices via monetary policy means.

    Which one of the following is correct in respect of the above statements?

    (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

    (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I

    (c) Statement-I is correct but Statement-II is incorrect

    (d) Statement-I is incorrect but Statement-II is correct

  • Keep UPI free. Fund it from the savings it generates

    Why in the News

    Parliament has passed the Taxation and Other Laws (Amendment) Bill, 2026, rewriting Section 10A of the Payment and Settlement Systems Act, 2007. That section barred any charge on Unified Payments Interface (UPI) and RuPay transactions. The amendment replaces the bar with an enabling provision, letting the government notify in future which payment modes may carry a charge. No charge is imposed today. The tension is that the cost of running UPI is real and the state’s compensating outlay is shrinking. The only fee instrument available for recovering that cost would be levied on the smallest transactions in the economy.

    What is the Merchant Discount Rate?

    1. Definition: The Merchant Discount Rate (MDR) is the percentage of a transaction value that a merchant pays for accepting a digital payment, deducted before the money reaches the merchant’s account.
    2. Card world origin: It is an inheritance from card payments, with the card issuer, the acquiring bank and the network each taking a slice. A physical card, a terminal and credit default risk give the fee something real to recover.

    What has the amendment to Section 10A actually changed?

    1. From prohibition to permission: A statutory bar on charging has been converted into a discretionary power to allow charging on notified modes.
    2. The trigger moves to the executive: Imposing a charge no longer needs Parliament, only a notification.
    3. The status quo is unchanged today: No charge has been imposed on any mode as of the amendment.
    4. Why it still matters: A right protected by statute and a right held at executive discretion are different guarantees for a merchant deciding whether to accept digital payment.

    What has UPI become?

    1. Volume and value: In 2025-26 UPI carried over 24,000 crore transactions, roughly 66 crore a day, worth about ₹314 lakh crore.
    2. Share: It accounts for some 85 per cent of India’s digital retail payments and nearly half of the world’s real time payments.
    3. Ticket size: The average transaction is about ₹1,300, and 86 per cent of merchant payments are below ₹500.
    4. Who transacts: Payments at that size are made to the vegetable seller, the auto driver and the kirana shop, so a charge is a levy on the smallest transactions of the poorest rather than on commerce in the abstract.
    5. What was achieved: No other country has made real time digital payment free, instant and universal, and the transition pulled hundreds of millions of Indians into the formal economy.

    Why is UPI treated as public infrastructure rather than a company’s product?

    1. Most used digital public good: After Aadhaar gave every Indian a digital identity, UPI is the most visible piece of digital public infrastructure, and the citizen reaches for it many times a day rather than once.
    2. A protocol, not a platform: It is an open, protocol based public good, a shared language for money instead of any single firm’s product.
    3. What the protocol did to banking: Before UPI each bank ran its own closed application. UPI asked banks only to open their programming interfaces to a shared protocol, so any application can move money between any two accounts at any two banks.
    4. External validation: The model is being studied and adopted by other countries.

    Why is the Merchant Discount Rate the wrong instrument for UPI?

    1. The recoverable costs do not exist: The point of sale machine is the customer’s own phone, running on data he has already paid for. There is no card, no terminal, no credit risk, and settlement is instant.
    2. The work done test: Telecom interconnection regulation pays a network only for the work it actually performs, and the same test applies to a payment rail.
    3. The work actually performed: When A pays B, A’s bank makes a debit entry, the National Payments Corporation of India (NPCI) issues a settlement instruction, and B’s bank makes a credit entry. No cash moves at any point.
    4. What that work costs: NPCI runs the entire switch for about ₹500 crore a year, which is some two paise a transaction.

    The funding gap is real even where the fee is wrong

    1. Providers earn nothing directly: Banks and payment providers bear real costs, and under zero MDR they receive nothing from a UPI transaction itself.
    2. The bridge is being withdrawn: The government has covered the gap with an incentive, and the outlay is projected to fall to about ₹437 crore from about ₹3,631 crore two years ago.
    3. Traffic is moving the other way: The volume the incentive supports is multiplying and the incentive itself is shrinking. The shortfall widens each year without any policy decision being taken.

    Who actually captures the savings digitisation creates?

    1. Currency printing: The Reserve Bank spends some ₹5,000 crore to ₹6,400 crore a year merely printing currency notes, which is more than the government spends keeping UPI free, before storage and movement of cash is counted.
    2. Channel cost at the bank: A counter transaction costs a bank ₹40 to ₹50 and an automated teller machine (ATM) withdrawal costs ₹19 in interchange alone. A UPI transaction costs a small fraction of either.
    3. The float: By making an account as usable as cash, UPI keeps money in accounts rather than idle in pockets, and that low cost float is what banks earn a spread on and lend against.
    4. The mismatch: The beneficiary of digitisation is the state and the bank, and the party a merchant fee would tax is the merchant, so the instrument does not follow the benefit.

    What would a Merchant Discount Rate cost the transition?

    1. Price sensitivity: India is intensely price sensitive, and a digital payment costing even a rupee more than cash sends many users back to cash.
    2. Pass through at the counter: A merchant charged MDR passes it on as a stated surcharge for digital, or refuses digital payment altogether.
    3. Scale of the extraction: Even 0.3 per cent on merchant payments would take some ₹27,000 crore a year out of a thin margin retail economy.
    4. Reversal risk: Telling a hundred crore users that what was always free now costs money is the surest way to slow, and even reverse, a transition still forming, collecting a little and losing a great deal.
    5. A large merchant carve out will not hold: Confining the charge to large merchants offers no lasting protection, because thresholds slip and definitions widen.

    What funding model could cover the cost without charging the user?

    1. Return a share of the savings: The state, as steward of the public good and no longer obliged to print and move the cash UPI displaces, should return a small, defined share of its savings to those who run the rails.
    2. Formula, not discretion: The support should be transparent and formula based, funded specifically from savings in currency management.
    3. Not a subsidy: It is payment for value delivered, on the same principle by which the state pays a transmission company to carry electricity.
    4. The price stays off the citizen: The design keeps the charge out of sight of the user, so no price tag ever appears in front of the person paying.

    Challenges to keeping UPI free

    1. The support is a Budget line, not an entitlement: An annual allocation can be cut without any change in law, so the guarantee is only as durable as one fiscal year. Eg. The incentive allocation has been cut sharply across two consecutive Budgets. Fix. Convert the support into a formula linked to measured currency management savings, so the amount tracks the service rather than the fiscal cycle.
    2. Two applications carry most of the volume: Concentration lets a handful of private applications set the terms of access for banks and merchants. Eg. Two private applications account for roughly 80 per cent of UPI volume, and the market share cap on them has been deferred repeatedly. Fix. Fund interoperable merchant acquisition through smaller banks and the Bharat Interface for Money application to widen the base.
    3. Charged rails already run beside the free ones: Credit products routed over the same interface carry a fee, so the free character of the system is already partial. Eg. From June 2026 a merchant discount rate applies to large value RuPay credit on UPI transactions. Fix. Publish a single schedule stating exactly which flows carry a charge, so a merchant sees the boundary before accepting a payment.
    4. Fraud losses sit outside the pricing debate: The system’s real cost includes reimbursing victims, which no fee structure currently funds. Eg. Digital payment fraud losses have crossed ₹22,000 crore. Fix. Build a lagged credit window for high risk first time transfers, so a fraudulent transfer can be reversed before withdrawal.
    5. Downtime carries no consequence: Bank side outages take users off the network at peak hours with no compensation obligation. Eg. Server downtime at major banks has repeatedly disrupted time sensitive payments. Fix. Set a published per bank uptime standard with penalties credited directly to affected users.

    Conclusion

    The statutory prohibition on charging for UPI is gone and the power to permit a charge now sits with the executive, even though no charge exists today. The cost of running the rails is genuine and the compensating outlay is falling, so the funding question cannot be deferred much longer. The unresolved choice is between recovering that cost from the merchant, which taxes the smallest transactions and risks reversing adoption, and recovering it from the currency management savings the state already books because UPI exists.

    “[2018] Which one of the following best describes the term “Merchant Discount Rate” sometimes seen in news?

    (a) The incentive given by a bank to a merchant for accepting payments through debit cards pertaining to that bank.

    (b) The amount paid back by banks to their customers when they use debit cards for financial transactions for purchasing goods or services.

    (c) The charge to a merchant by a bank for accepting payments from his customers through the bank’s debit cards.

    (d) The incentive given by the Government to merchants for promoting digital payments by their customers through Point of Sale (PoS) machines and debit cards.

  • FDI policy rejig for border nations spur Rs 5k cr investment: DPIIT

    Why in the News

    A relaxation in India’s rules on investment from land bordering countries has drawn 29 foreign direct investment (FDI) proposals worth ₹4,895.65 crore up to 20 August 2026. The relaxation was notified in March 2026. It permits a foreign entity carrying non controlling beneficial ownership of up to 10 per cent from a land bordering country to invest through the automatic route. Press Note 3 of 2020 had required prior government approval for any such investment, however small that land border shareholding was. What is now tested is whether a shareholding threshold can separate incidental Chinese exposure inside a global fund from Chinese strategic control of an Indian asset.

    What is Press Note 3 of 2020?

    1. The restriction: Imposed in April 2020, it made government approval mandatory for investment from any country sharing a land border with India.
    2. Stated purpose: It was aimed at preventing opportunistic takeovers of Indian firms during the Covid-19 pandemic, and stayed in force amid heightened national security concerns after the Galwan clash later that year.
    3. Country neutral drafting: The framework named no country, and China is the largest source of investment among India’s land neighbours.
    4. Uneven bite: Entities of Bangladesh and Pakistan can invest only through the government route. Flows from Nepal, Myanmar, Bhutan and Afghanistan are very small as a share of India’s total foreign investment.

    What conditions does the relaxed route carry?

    1. Indian control retained: The majority shareholding and control of the investee entity must rest at all times with resident Indian citizens, or with resident Indian entities that are themselves owned and controlled by resident Indian citizens.
    2. Threshold is a ceiling, not a waiver: A land border holding above 10 per cent still routes the investment through government approval, so the automatic route covers only diluted exposure.
    3. Time bound clearance for named goods: A 60 day deadline was approved for clearing proposals from land bordering countries, including China, in capital goods, electronic capital goods, electronic components, polysilicon, and ingot wafer for solar cells.

    Where has the relaxed route drawn money from?

    1. Sectors: The proposals span information technology, artificial intelligence, information and communication, manufacturing, pharmaceuticals, data centres and transport services.
    2. Jurisdictions: They were reported by investors and entities based in Mauritius, the United States, the Republic of Korea, Japan, Singapore, Luxembourg and the Cayman Islands, among others.
    3. Stated gain: The government’s own assessment is that the reform gives investors greater certainty, cuts transaction time and strengthens ease of doing business in India.

    Where has the Centre gone further than the ownership threshold?

    1. A strategic sector joint venture: In July 2026 the Centre cleared a joint venture between Dixon Technologies (India) Limited and Vivo Mobile India Limited for manufacturing electronic devices and smartphones, one of the first major approvals to Chinese investment in a strategic sector.
    2. Entry into power tenders: The Finance Ministry in July allowed four Chinese power equipment manufacturers with factories in India to bid for government tenders on critical power projects.
    3. A procurement exemption: TBEA Energy, Nanjing Electric India, New Northeast Electric India and Taikai Electric (India) were exempted from the public procurement rule requiring entities from land bordering countries to register with the relevant Indian authority before bidding.
    4. What is at stake in that equipment: The four firms make transformers, wires, high voltage switchgear and gas insulated switchgear used in transmission lines. New Northeast Electric India lists at least 11 transmission line projects across India.

    Challenges to the revised land border investment framework

    1. Beneficial ownership is hard to trace through layers: A 10 per cent test presumes the ultimate holder is visible, which layered holding structures defeat. Eg. Several of the reported proposals came through Mauritius and the Cayman Islands. The ultimate holder is not on the local register in either jurisdiction. Fix. Require a declaration of the ultimate beneficial owner at every layer, verified against the significant beneficial ownership register maintained under the Companies Act, 2013.
    2. A shareholding cap does not bound influence: Control travels through contracts as much as through equity. Eg. A minority holder with board nomination rights or a sole technology licence can direct a joint venture without owning a majority. Fix. Test control by board composition and contractual veto rights, not by shareholding percentage alone.
    3. Screening capacity is spread thin: No single body owns the security review of an inbound proposal. Eg. Screening runs across the Department for Promotion of Industry and Internal Trade, the Ministry of Home Affairs and the administrative ministry, each with its own timeline. Fix. Constitute a standing inbound investment security review committee with a statutory disposal deadline.
    4. Technology dependence persists in the sectors being opened: Approval eases entry without changing who owns the process knowledge. Eg. India imports most of its polysilicon and ingot wafer requirement for solar cells. Fix. Tie approval in those goods to a phased technology transfer and a rising domestic sourcing commitment.
    5. The government route stays slow for everyone else: Only the notified goods got a deadline, so other proposals still face open ended review. Eg. Land border proposals outside the notified list have historically taken well over a year to clear. Fix. Extend the 60 day discipline to every proposal on the government route, with reasons recorded for any extension.

    Conclusion

    The relaxed framework has been operative since March 2026 and has produced 29 reported proposals in five months. Press Note 3 itself stays on the books for any land border holding above the threshold, so the restriction has been narrowed rather than withdrawn. The next milestone is disposal of proposals under the 60 day window for the notified goods, and whether the Dixon and Vivo clearance becomes a template for a wider, sector by sector opening.

    Foreign Direct Investment in India

    1. About: Foreign direct investment is cross border investment that establishes a lasting interest in an enterprise abroad, in the definition used by the Organisation for Economic Cooperation and Development.
    2. Routes: Most sectors permit 100 per cent foreign investment through the automatic route, and the remainder require prior government approval.
    3. Cumulative scale: India’s cumulative inflows crossed about $1.14 trillion between April 2000 and December 2025, with nearly 70 per cent of that arriving in the last decade.
    4. Recent flows: Gross inflows reached a three year high of $81 billion in 2024-25, led by services and manufacturing.

    Laws and Rules Governing Foreign Investment

    1. Foreign Exchange Management Act, 1999: The parent statute governing cross border transactions and capital account flows into and out of India.
    2. Foreign Exchange Management (Non-debt Instruments) Rules, 2019: Notified by the Finance Ministry, these fix sectoral caps, entry routes and pricing guidelines for equity investment.
    3. Consolidated FDI Policy Circular: A single compiled statement of sectoral policy, which Press Notes amend between editions.
    4. Competition Act, 2002: Acquisitions above notified thresholds need Competition Commission of India clearance.

    Challenges in Attracting Foreign Direct Investment

    1. Policy unpredictability: Rules that change mid cycle force investors to restructure entities already built. Eg. Repeated shifts in e-commerce foreign investment norms forced marketplace operators to redraw their seller structures. Fix. Publish a standstill period between the notification of a sectoral rule change and its taking effect.
    2. Land acquisition: Site control is the binding constraint on greenfield manufacturing. Eg. POSCO abandoned its Odisha steel project after a decade of unresolved land disputes. Fix. Build titled, pre cleared land banks held by state industrial corporations and offered on long lease.
    3. Geographic concentration: Inflows cluster in services and a few urban states. Eg. A handful of states absorb the bulk of equity inflows reported each year. Fix. Offer differential incentives for greenfield investment in aspirational districts.
    4. Intellectual property enforcement: Weak enforcement raises the risk premium on technology intensive investment. Eg. India remains on the United States Priority Watch List on intellectual property enforcement. Fix. Create dedicated commercial intellectual property benches with fixed disposal timelines.
    5. Clearance friction across governments: A central approval does not deliver the state permissions a project actually needs. Eg. The National Single Window System still does not carry every state level clearance. Fix. Make full state onboarding to the single window a condition for central infrastructure co-funding.

    Back2Basics: Department for Promotion of Industry and Internal Trade

    1. Parent ministry: It sits under the Ministry of Commerce and Industry. It was the Department of Industrial Policy and Promotion until internal trade was added in 2019.
    2. Policy mandate: It frames and administers the Consolidated FDI Policy and issues the Press Notes that amend it.
    3. Programmes run: It runs Startup India and Make in India, and maintains the National Single Window System.

    “[2020] With reference to Foreign Direct Investment in India, which one of the following is considered its major characteristic?

    (a) It is the investment through capital instruments essentially in a listed company.

    (b) It is a largely non-debt creating capital flow.

    (c) It is the investment which involves debt-servicing.

    (d) It is the investment made by foreign institutional investors in the Government securities.

  • Centre notifies key scheme to manufacture mobile phones

    Why in the News

    The Ministry of Electronics and Information Technology (MeitY) has notified the Mobile Phone Manufacturing Scheme (MPMS), a ₹62,500 crore programme incentivising domestic assembly of smartphones and greater local value addition. The Union Cabinet approved the scheme on 15 July 2026. It succeeds the Production Linked Incentive Scheme for Large Scale Electronics Manufacturing, which ran from 2020 to the last financial year and rewarded incremental handset output from any qualifying firm. The new scheme splits that single track in two, creating a separate and richer channel for brands owned by Indian citizens and holding their intellectual property in India. What is contested is whether incentive design alone can move India from assembling other countries’ brands to owning its own.

    Components of the Mobile Phone Manufacturing Scheme

    1. Two parts: The notification divides the scheme in two, one part incentivising mobile phone manufacturing and one part supporting Indian mobile phone brands.
    2. Part 1, the assembly incentive: A base incentive on assembly tapers from 2.75 per cent to 2.25 per cent across the five year tenure. Applicable rates run from 2.25 per cent to 5 per cent depending on the year and on incremental sales.
    3. The domestic sourcing add on: An additional 1.5 per cent is payable on domestic component sourcing, built up from individual component incentives ranging from 0.2 per cent to 0.5 per cent.
    4. Part 2, the Indian brand track: An Indian owned brand draws a flat 5 per cent incentive for the full tenure, plus a domestic design and research and development incentive of 3 per cent.

    How does a firm actually earn the incentive?

    1. Turnover gate: Mobile phone companies, including electronics contract manufacturers, need a turnover of ₹10,000 crore in 2025-26 to qualify. Electronics manufacturing services firms with 51 per cent Indian ownership qualify at ₹1,000 crore.
    2. Growth gate: Incentives are disbursed only on sales beyond 115 per cent of the previous financial year’s production. A unit that produced ₹10 crore worth of phones in the preceding year and ₹12 crore in the next draws incentive on ₹50 lakh alone.
    3. Sourcing condition: The 1.5 per cent additional incentive applies only where a firm sources domestically for at least a quarter of the phones it sells in that financial year.
    4. No earmarking: The corpus is fungible overall, so no amount is reserved for domestic players. Foreign phonemakers face a higher bar to draw incentive, and they draw it from the same pool.

    What does the scheme change for Indian brands?

    1. Ownership test: An Indian brand must be majority owned by Indian citizens and incorporated in India, with intellectual property and trademarks held locally.
    2. No sales floor: Indian brands are exempt from the minimum sales threshold that applies to other brands, and their baseline is fixed at 2025-26.
    3. Stated intent: The Union Minister for Electronics and Information Technology framed the shift as one of Indian brand, Indian design and Indian intellectual property.
    4. Discretionary channel: An empowered committee will make recommendations to the government on Indian brand applications for incremental incentives and for non fiscal support.

    What has the assembly led phase achieved, and where has it stopped?

    1. Import to export: Around 70 per cent to 75 per cent of phones sold in India were imports in 2014-15, and the country is now an exporter of finished handsets.
    2. Global position: India is the second largest phone manufacturer in the world, and practically all phones sold in the country are made in it.
    3. Shallow value: Domestic value addition in mobile phone manufacturing stands at 23 per cent, so most of the value in an Indian assembled handset is still created abroad.
    4. A ceiling exists: The benchmark set by Chinese phone assembly units is itself bounded, because components in electronics value chains crisscross the globe several times before a device is finished.

    What does the scheme set out to achieve by 2030-31?

    1. Production: Cumulative production, measured as the combined sale value of finished products, is targeted at ₹39 lakh crore by the end of the scheme.
    2. Exports: Cumulative exports over the same period are targeted at ₹5 lakh crore.
    3. Value addition: The stated goal is to double overall domestic value addition from a band of 18 per cent to 23 per cent up to a band of 35 per cent to 40 per cent.
    4. Employment: The Secretary of the Ministry of Electronics and Information Technology put direct job creation under the scheme at 60,000.

    Why does the government treat phone assembly as a gateway sector?

    1. Skill and technology spillover: Technology and skill transfer from handset lines is stated to enable adjacent hardware production, in laptops, tablets and smart watches.
    2. New device categories: The same capability base is expected to carry into gaming consoles, drone manufacturing and medical devices.
    3. Beyond electronics: Components and automobile windshields are named as further beneficiaries of the manufacturing ecosystem the sector builds.

    Challenges to the Mobile Phone Manufacturing Scheme

    1. Incentive concentrates in a few assemblers: A single fungible pool rewards volume, and volume already sits with a small set of contract manufacturers. Eg. Under the earlier electronics scheme, most disbursed incentive flowed to a handful of contract assemblers serving Apple and Samsung. Fix. Ring fence a defined tranche of the corpus for the Indian brand track instead of leaving the whole corpus open to competition.
    2. The turnover gate excludes the firms the scheme names: A ₹1,000 crore revenue floor sits above what the surviving Indian handset brands turn over. Eg. Micromax and Lava operate at a fraction of the revenue of the contract assemblers they would compete with for the same pool. Fix. Add a staged eligibility ladder with a lower entry threshold and a rising production commitment.
    3. The sourcing bonus has a thin supplier base to draw on: Displays, camera modules and application processors are not made in India at scale. Eg. Display panels and camera modules for handsets assembled in India are imported largely from China, South Korea and Vietnam. Fix. Sequence disbursement under the Electronics Component Manufacturing Scheme ahead of assembly incentive, so a supplier base exists before the bonus is claimed.
    4. A demand slump erases a year’s eligibility: Incentive accrues only above a fixed growth threshold over the prior year, so a flat year pays nothing. Eg. Covid disruption in 2020-21 left applicants under the earlier electronics scheme unable to meet their first year incremental production targets. Fix. Allow an unmet incremental target to be carried into the following year within the same tenure.
    5. Locally held intellectual property can be bought rather than built: The Indian brand test rests on registered ownership, which an assignment satisfies without design capability moving to India. Eg. Contract design houses in Shenzhen supply reference designs that brands across Asia rebadge as their own. Fix. Tie the design and research incentive to audited domestic engineering headcount and to patents filed from India.

    Conclusion

    The Mobile Phone Manufacturing Scheme has moved from Cabinet approval to notification, with operational guidelines issued on 21 August 2026 and a tenure running to 2030-31. The next milestone is the application round. Assemblers file against the turnover gate. Indian brands file separately for the brand track. Whether the second track becomes a genuine channel or a minority claim on a shared pool will be visible in the empowered committee’s first set of recommendations.

    “[2025, GS3, 15 marks] Discuss the rationale of the Production Linked Incentive (PLI) scheme. What are its achievements? In what way can the functioning and outcomes of the scheme be improved?”

  • How will Gaganyaan’s thermal shield protect the crew?

    Why in the News

    The Gaganyaan crew module will hit the atmosphere at 7,500 to 8,000 metres per second on return, with its exterior reaching 1,800 degrees Celsius while the structure must stay below 150 degrees Celsius. The shield chosen to hold that gap is a sacrificial ablative layer 30 to 35 millimetres thick, a choice driven by the mission’s single use design and India’s own re entry heritage rather than by peak performance.

    What is a thermal protection system?

    1. What it does: A thermal protection system is the outer layer that keeps a re entering vehicle’s structure and interior within survivable temperature while its exterior is exposed to the heat of atmospheric entry.
    2. Why it is needed: Almost all of the crew module’s kinetic energy is dissipated into the atmosphere as heat energy, and the small portion directed back towards the module is still intense enough to melt it.
    3. What it protects: It maintains the module’s structural integrity and keeps the interior within the temperature limit the structure and the crew can tolerate.
    4. How it is classified: Systems are grouped by how they remove heat, into ablative, radiative and heat sink types.

    What is heat flux?

    1. Definition: Heat flux is the rate at which heat energy passes through a unit area of a surface, measured in watts per square metre.
    2. Why it varies on a capsule: It is highest at the point of the vehicle that meets the airflow first, which is why the nose cap carries the most demanding shield material.

    What is a boundary layer?

    1. Definition: The boundary layer is the thin region of gas immediately next to a moving vehicle’s surface, where the flow is slowed by contact with that surface.
    2. Why it matters in ablation: Gases escaping from the decomposing shield thicken and cool this layer, which blocks intense heat from being transferred into the module.

    Why is atmospheric re entry harder than ascent for a crewed mission?

    1. Ascent is controlled and gradual: A rocket accelerates slowly through the atmosphere on the way up specifically to keep the mechanical loads on the vehicle to a minimum.
    2. Re entry cannot be aborted: Once the descent begins there is no provision to abort the mission, so every system must work through to splashdown.
    3. The crew cannot intervene: There is only a limited role for the crew to intervene and correct any system non conformance during descent.
    4. The event is too fast for human correction: Atmospheric descent is incredibly fast and the deceleration forces change constantly, and human response times are simply too high to manually correct a sudden system abnormality.
    5. What follows from this: All systems must therefore be made robust enough to withstand the scorching conditions of re entry on their own, since design margin substitutes for intervention.

    What thermal conditions must the Gaganyaan crew module survive?

    1. Entry velocity: The crew module will hit the atmosphere at a speed of 7,500 to 8,000 metres per second on return from its orbit around the earth.
    2. Energy dissipation: More than 99 per cent of that kinetic energy will be dissipated into the atmosphere as heat energy.
    3. Exterior temperature: The exterior of the module will encounter temperatures as high as 1,800 degrees Celsius in some regions.
    4. Shield thickness: The thermal protection system is just 30 to 35 millimetres thick.
    5. Interior limit: That layer must keep the module’s temperature safely below 150 degrees Celsius while performing the task of maintaining structural integrity.

    How do ablative, radiative and heat sink systems each remove heat?

    1. Ablative: A single use system that removes heat energy by sacrificing its own layers through chemical and physical processes, absorbing extreme quantities of thermal energy and chemically decomposing into a protective layer of solid char and outgassing vapours.
    2. The decomposition physically carries heat away from the module as the material burns off, and the escaping gases create a cooler boundary layer that blocks heat transfer into the module.
    3. Carbon phenolic and silica phenolic are examples of ablative materials.
    4. Radiative: A system that absorbs the extreme heat of re entry and then releases it back into space as electromagnetic radiation, primarily in the infrared spectrum and also as visible light when it is extremely hot.
    5. It remains intact and withstands the heat without melting or degrading, which makes it suited to reusable re entry vehicles.
    6. Heat sink: A system that absorbs heat energy and raises its own temperature without melting or changing phase in any other way.
    7. Copper and aluminium are examples of heat sink materials.

    Why has the Indian Space Research Organisation chosen an ablative shield for the crew module?

    1. It matches the mission’s design philosophy: The Gaganyaan crew module is a single use vehicle, and an ablative system is a single use system, so the shield’s life and the module’s life are the same.
    2. It is proven and robust: The Indian Space Research Organisation (ISRO) has selected it as a proven and highly robust solution rather than the highest performing one available.
    3. It tolerates fluctuating heat loads: Ablative heat shields can easily handle fluctuating heat loads to protect the structure underneath, which matters when the descent profile varies.
    4. Radiative systems are less forgiving: Any design error in a radiative system can quickly cause dangerous overheating, so its margin for error is narrower.
    5. It avoids a maintenance burden: An ablative system withstands an extreme thermal load without requiring complex or delicate surface maintenance between flights.
    6. It avoids the reusable system’s cost structure: By avoiding the expensive manufacturing, specialised inspection and complex installation processes associated with a reusable radiative system, ISRO has taken the safer and more cost effective option.

    Does choosing a single use shield trade away reusability for safety?

    1. What is given up: A sacrificial shield is consumed on every flight, so a new heat shield must be manufactured and installed for each mission rather than inspected and reflown.
    2. The recurring cost consequence: Per flight cost stays flat across a programme instead of falling with flight rate, which is the opposite of the economics a high cadence programme needs.
    3. Why the trade is correct for this mission: Reusability only pays back over a high flight rate, and a first generation crewed programme flying occasional missions never reaches that rate.
    4. Where the trade stops working: A sustained crew rotation programme to an orbital station changes the flight rate, at which point the reusable radiative option becomes the economically relevant one.
    5. The safety side of the trade: The ablative system’s tolerance of fluctuating heat loads and its independence from surface inspection are precisely the properties a programme flying its first crew needs most.

    What does India’s own re entry heritage contribute to the Gaganyaan shield?

    1. The first re entry mission: The Space Capsule Recovery Experiment, India’s maiden re entry mission, used a carbon phenolic ablative to protect the module’s nose cap, where heat flux was the highest.
    2. The crew module demonstration: The Launch Vehicle Mark-3 (LVM3) flew the Crew Module Atmospheric Re-entry Experiment (CARE) in 2014. That flight successfully demonstrated crew module re entry using an ablative thermal protection system.
    3. What that established: The 2014 mission established the foundational technology that is now being used in the Gaganyaan programme, so the shield is an inheritance rather than a new development.
    4. Why heritage reduces risk: Material characterisation, manufacturing process and flight data already exist for the ablative route, which removes the qualification uncertainty a new material class would carry.
    5. The programme position: The Gaganyaan crew module is built on this ablative heritage and on the lessons learned from both earlier missions.

    What does the SpaceX Crew Dragon comparison show about ablative shield design choices?

    1. United States, the Crew Dragon shield: The Crew Dragon capsule of SpaceX uses an ablative material named phenolic impregnated carbon ablator, or PICA, a lightweight carbon fibre matrix filled with a phenolic resin.
    2. The shared design logic: A crewed capsule operator with a very different cost structure has arrived at the same ablative class of solution, which indicates the choice follows from the capsule form rather than from budget constraint.
    3. The design feature that differs: PICA’s lightweight carbon fibre matrix trades density for mass saving, while carbon phenolic of the kind flown on India’s first re entry mission is denser and carries higher heat flux at the nose.
    4. The limit of this comparison: This is the single foreign system named in the evidence here, so it establishes that ablative shielding is the standard choice for crewed capsules, not a ranked comparison of national capsule programmes.

    Challenges to the Gaganyaan thermal protection system

    1. Ground testing cannot reproduce full re entry: No ground facility reproduces the combined velocity, heat flux and duration of an orbital re entry, so qualification relies on partial simulation and analysis. Eg. Arc jet plasma facilities test coupons at representative heat flux but not at the full 7,500 to 8,000 metres per second entry velocity.
    2. Bond line integrity over a curved surface: A 30 to 35 millimetre layer must adhere uniformly over the module’s full curvature, and a bond defect creates a local hot path into the structure. Eg. Shuttle era thermal protection failures originated in localised damage to the protective layer rather than in the material’s bulk performance.
    3. Predicting the recession rate: Ablative design depends on predicting how much material burns off, and an over prediction adds dead mass while an under prediction risks burn through. Eg. Nose cap regions carry the highest heat flux and therefore the largest uncertainty in recession estimates.
    4. Mass penalty on the launch vehicle: A sacrificial shield sized with margin is heavy, and every kilogram of shield reduces the payload the human rated launcher can carry. Eg. The human rated LVM3 has to lift the crew module, service module and shield together to a 400 kilometre orbit.
    5. Manufacturing repeatability: Each mission needs a newly manufactured shield, so process variation between production batches becomes a flight safety variable rather than a quality issue. Eg. Carbon phenolic layup is a manual intensive process where resin content and fibre orientation must be reproduced identically each time.
    6. Recovery environment after splashdown: A charred shield must survive water impact and sea recovery without compromising the crew compartment. Eg. India’s first re entry mission was recovered from the Bay of Bengal, which is the recovery zone the crewed programme also plans to use.
    7. Single point criticality: With no abort provision once descent begins and limited crew intervention, the shield has no backup system to fall back on. Eg. Human response times are too high to correct a sudden thermal abnormality during a descent where deceleration forces change constantly.

    Conclusion

    The Gaganyaan crew module’s protection against a 1,800 degrees Celsius re entry rests on a 30 to 35 millimetre ablative layer that sacrifices itself to carry heat away and hold the structure below 150 degrees Celsius. The choice of an ablative over a radiative system follows from the module’s single use design, its tolerance of fluctuating heat loads and the technology base established by India’s first re entry mission and the 2014 crew module demonstration. The programme’s current status is that the shield is qualified on this heritage, with the first uncrewed test flight launching shortly.

    Human Spaceflight Programme of India

    1. What it is: Gaganyaan is India’s human spaceflight programme, aimed at demonstrating the capability to launch a crew to low earth orbit and return them safely to Indian waters.
    2. Mission profile: The mission is designed to carry a crew of up to three to an orbit of about 400 kilometres for a mission duration of up to three days, followed by splashdown recovery.
    3. The launch vehicle: The launcher is a human rated version of the LVM3, designated the Human rated Launch Vehicle Mark-3 (HLVM3), modified with additional redundancy and a crew escape system.
    4. The orbital module: The crew module and the service module together form the orbital module, with the crew module being the pressurised habitable segment that returns.
    5. Institutional base: The Human Space Flight Centre was established at Bengaluru in 2019 to lead the programme, with the Vikram Sarabhai Space Centre responsible for launch vehicle and re entry systems.
    6. The longer roadmap: India’s stated goals extend to the Bharatiya Antariksh Station by 2035 and a crewed lunar landing by 2040.

    Laws and Treaties Governing Space Activities

    1. Outer Space Treaty, 1967: Makes States internationally responsible for national space activities, whether carried on by governmental or non governmental entities, and bars national appropriation of outer space.
    2. Rescue Agreement, 1968: Obliges States to assist astronauts in distress and to return them and any recovered space objects to the launching authority.
    3. Liability Convention, 1972: Makes a launching State absolutely liable for damage caused by its space object on the surface of the earth or to aircraft in flight.
    4. Registration Convention, 1975: Requires launching States to maintain a national registry of space objects and to furnish details to the United Nations.
    5. Moon Agreement, 1979: Declares the Moon and its resources the common heritage of mankind, and India has signed but not ratified it.
    6. Indian Space Policy, 2023: Defines the roles of ISRO, the Indian National Space Promotion and Authorisation Centre, NewSpace India Limited and non governmental entities in the Indian space ecosystem.
    7. Space Activities Bill, 2017: A draft domestic law to license and regulate private space activity in India, which was circulated for comment and never enacted.
    8. Satellite Communications Policy and spectrum rules: Govern authorisation of satellite services, with spectrum assignment handled under the Telecommunications Act, 2023.
