  • ISRO launches advanced imaging satellite EOS-05

    ISRO launches advanced imaging satellite EOS-05

    Why in the News

    The Indian Space Research Organisation (ISRO) has launched the advanced earth observation satellite EOS-05 aboard the Geosynchronous Satellite Launch Vehicle (GSLV-F17).

    What is EOS-05?

    1. What makes it a first: It is India’s first dedicated imaging satellite operating from geosynchronous orbit, where a satellite’s orbital period matches the earth’s rotation so it holds position over the same region.
    2. What it carries: The satellite has multi band operating capabilities and an operational life of nine years.
    3. What it replaces: It takes the place of EOS-03, lost in the unsuccessful GSLV-F10 mission of August 2021.
    4. Where it is now: ISRO has confirmed that the valves are operating, the solar panel is deployed and the satellite’s health is intact, and the orbit will be raised over the coming days to place it on the geo platform.

    Why does imaging from geosynchronous orbit matter?

    1. It removes the revisit gap: A low earth orbit imaging satellite passes over a given area only periodically, while a geosynchronous platform holds the same region in view continuously.
    2. The applications are time sensitive: Near real time imagery serves agriculture, environment monitoring and disaster management, where the value of an image collapses if it arrives days after the event.
    3. The data is described as strategic: ISRO has stated that the platform will supply important strategic data supporting “national activities”, which is the standard formulation for defence and security use.
    4. The trade off is resolution: Ground resolution falls as orbital distance rises, so a geosynchronous imager buys persistence at the cost of the fine detail a low orbit satellite returns.

    What does the mission say about the launch vehicle?

    1. It was the heaviest payload the vehicle has carried: The 2,367 kg satellite is the heaviest ISRO has injected using this launch vehicle.
    2. The growth is measurable against the first flight: The first GSLV flight, GSLV-D1, carried a payload of 1,536 kg.
    3. The gain came from two specific changes: ISRO has attributed the improvement to optimising the vehicle’s structural mass and improving its propulsion systems.
    4. The vehicle configuration: The GSLV is a three stage, 51.7 metre vehicle with a lift off mass of 420.5 tonnes, and its third stage is cryogenic (using propellants stored as liquids at extremely low temperatures, which yields higher efficiency than conventional stages).
    5. The mission count: This was the 19th GSLV mission and the 107th launch from Sriharikota.

    Why had ISRO stopped launching?

    1. Two consecutive vehicle failures: The PSLV-C61 mission failed on 18 May 2025, and the PSLV-C62 mission carrying the EOS-N1 earth observation satellite failed on 12 January 2026.
    2. The response was a deliberate halt: ISRO adopted a cautious approach after the back to back failures and refrained from carrying out further launches.
    3. The cost was an entire quarter: Seven missions, including this one, had been scheduled for the first quarter of 2026, and no satellite was launched during the period.

    Challenges to India’s earth observation programme

    1. Launch cadence lags the manifest: A single quarter of stood down launches pushes an entire year’s schedule, and satellites waiting for a slot age against their design windows. Eg. Seven missions planned for the first quarter of 2026 were carried forward without a single flight.
      The Fix: Move routine earth observation payloads onto the Small Satellite Launch Vehicle and commercial providers, so a review of one vehicle does not freeze the whole manifest.
    2. The cryogenic stage remains the vehicle’s hardest element: The GSLV’s performance depends on a stage that took India close to two decades to prove. Eg. The first fully successful flight of the indigenous cryogenic upper stage came only with GSLV-D5 in January 2014.
      The Fix: Sustain a parallel production line and ground test cadence for cryogenic stages, so a flight failure does not idle the vehicle for want of a qualified replacement stage.
    3. Optical imaging fails when it is needed most: An optical imager cannot see through cloud, and India’s worst flood and landslide events occur during the monsoon under continuous cloud cover. Eg. Disaster response during the monsoon depends on radar imaging satellites such as EOS-04 rather than on optical payloads.
      The Fix: Pair the geosynchronous optical platform with a scheduled radar imaging constellation, so persistent coverage survives the cloud season.
    4. Imagery is only as useful as its downstream users: Data value depends on agencies and states being able to ingest and act on it rather than on the satellite alone. Eg. Access to national imagery is routed through the Bhuvan platform and the National Remote Sensing Centre, and uptake varies sharply across state departments.
      The Fix: Fund state level remote sensing application centres with standing analyst posts, so imagery reaches district administrations as advisories rather than as raw files.

    Conclusion

    The satellite is in a transfer orbit and not yet at its station, so the mission’s outcome is settled only once orbit raising is complete and the platform is commissioned. The capability it brings is persistence over one region rather than sharper pictures, which suits warning and monitoring more than reconnaissance. The launch pause has ended on the vehicle that had the weaker record, which is the more demanding of the two returns to flight. What to watch is whether the remaining missions deferred from the first quarter of 2026 now fly on schedule, since a single successful launch does not by itself restore a cadence.

    “[2018] With reference to India’s satellite launch vehicles, consider the following statements :

    1.PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites.

    2.Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth.

    3.GSLV Mk III is a four-stage launch vehicle with the first and third stages using solid rocket motors, and the second and fourth stages using liquid rocket engines.

  • WMO warns of ‘very’ strong El Nino, to last until February 2027

    WMO warns of ‘very’ strong El Nino, to last until February 2027

    Why in the News

    The World Meteorological Organization (WMO) has warned of an impending very strong El Nino that is expected to strengthen and last until February 2027. Its Secretary General stated that El Nino is firmly established and has the potential to deliver a massive blow to communities and economies across the world.

    How does El Nino work?

    1. The mechanism: El Nino is a periodic warming of sea surface temperatures in the equatorial and eastern Pacific Ocean, caused by a weakening of the trade winds.
    2. Why it travels: The warming moves the region where heat and moisture rise into the atmosphere, which alters temperature and rainfall patterns far from the Pacific.
    3. Its rhythm: The phenomenon recurs every two to seven years and a single event lasts up to about twelve months.
    4. What it produces: It is known to trigger heatwaves, wet spells and extreme temperatures.

    How strong is this event, and how is that graded?

    1. The index used: Intensity is determined by the sea surface temperature averaged over three months in the Nino 3.4 region along the equatorial Pacific Ocean.
    2. The readings so far: The index surpassed 1.5 degrees Celsius above normal during May to July and crossed 2 degrees Celsius above normal in July.
    3. The persistence forecast: The likelihood of El Nino continuing through February 2027 is put at close to 100 percent, the first time the agency has forecast an event at that degree of certainty.
    4. A possible record: Exceptionally warm Pacific temperatures make this potentially the strongest El Nino since monitoring began.

    What does it mean for India this season?

    1. The monsoon largely escaped: The India Meteorological Department (IMD) confirmed that rainfall in the later half of August came under the influence of the developing El Nino. With three fourths of the season over, the monsoon has largely escaped it.
    2. A countervailing signal: A positive phase of the Indian Ocean Dipole is expected to develop during September to November, with a seasonal mean value of 0.9 degrees Celsius.
    3. Why the offset matters: A positive Dipole strengthens rainfall over the Indian region and can therefore work against El Nino’s drying influence.
    4. The offset is not assured: The Dipole swung briefly towards the positive phase in late August and then returned to neutral.

    What is the WMO doing about it?

    1. A mobilisation without precedent in the agency: The Secretary General described this as the largest mobilisation with National Meteorological and Hydrological Services in the WMO’s fifty year history.
    2. Why those agencies: National meteorological services are the bodies that convert a global seasonal outlook into forecasts and warnings people can act on.
    3. Impacts are already visible: Droughts and floods are already causing disruption, and the agency expects these to intensify as the event strengthens.
    4. The recent record: Europe recorded one of its hottest summers in recent decades this year, and August brought record temperatures in many parts of the globe.

    Challenges to acting on an El Nino warning

    1. A seasonal outlook is not a local forecast: El Nino shifts the odds of dry conditions across a season and cannot say what a particular district receives in a particular week. Eg. The 2023 monsoon closed about 6 percent below normal for India as a whole, and several subdivisions still recorded surplus rain.
      The Fix: Issue impact based forecasts at district level that translate the seasonal outlook into expected effects on sowing dates, reservoir filling and power demand.
    2. The Indian Ocean modifies the Pacific signal: El Nino’s effect on the Indian monsoon depends on the state of the Indian Ocean, so an El Nino year is not automatically a drought year. Eg. The 1997 event was among the strongest recorded and the Indian monsoon that year was normal.
      The Fix: Publish the El Nino and Dipole outlooks as one combined regional signal rather than as two separate advisories a user has to reconcile.
    3. Warnings stop short of the last mile: Early warning coverage remains uneven for small farmers and fishing communities who cannot act on a technical bulletin. Eg. The United Nations Early Warnings for All initiative exists because a large share of the world’s population is still not covered by any early warning system.
      The Fix: Route advisories through State agriculture extension and fisheries departments in local languages, tied to one specific recommended action.
    4. Reservoirs are operated on inflows, not on forecasts: Storage decisions respond to water already received, so a deficit is managed only after it has appeared. Eg. Southern region reservoirs stood far below their ten year average through the summer of 2024, after the previous year’s deficient monsoon.
      The Fix: Write seasonal forecasts into reservoir rule curves so storage is conserved in advance of a forecast dry season.
    5. The consequences outlast the monsoon: El Nino affects the rabi season and global crops, so the exposure continues well after the Indian monsoon withdraws. Eg. India restricted rice exports during the 2023 El Nino year on domestic supply concerns.
      The Fix: Set buffer stock and import cover decisions against the forecast horizon rather than against the harvest just completed.

    Conclusion

    The forecast has settled the question of whether the event arrives and left open only what is done before it peaks. India’s monsoon has escaped this season, so the exposure shifts to the rabi crop, to reservoir storage and to the summer that follows. The marker to watch is whether the Indian Ocean Dipole holds its positive phase long enough to blunt the Pacific signal over the region.

    Back2Basics: Indian Ocean Dipole

    1. What it is: The Indian Ocean Dipole is the difference in sea surface temperature between the western and the eastern parts of the tropical Indian Ocean.
    2. Positive phase: The western Indian Ocean is warmer than the eastern part near Indonesia, which favours stronger rainfall over the Indian subcontinent and East Africa.
    3. Negative phase: The eastern part is warmer, which suppresses rainfall over India and shifts it towards Indonesia and Australia.
    4. How it is tracked: It is measured as the Dipole Mode Index, the temperature gradient between the two poles of the ocean.

    [2017] With reference to ‘Indian Ocean Dipole (IOD)’ sometimes mentioned in the news while forecasting Indian monsoon, which of the following statements is/are correct?

    1. IOD phenomenon is characterized by a difference in sea surface temperature between tropical Western Indian Ocean and tropical Eastern Pacific Ocean.

    2. An IOD phenomenon can influence an El Nino’s impact on the monsoon.

    Select the correct answer using the code given below:

    (a) 1 only

    (b) 2 only

    (c) Both 1 and 2

    (d) Neither 1 nor 2

  • In a first, Rlys to build 6 freight lines with pvt firms using highways’ hybrid funding model

    Why in the News

    The Public Private Partnership Appraisal Committee under the Ministry of Finance has approved six railway lines spanning 647 km along freight corridors, to be built under the Hybrid Annuity Model. This is the first time Indian Railways will implement a project under the model, which was developed for the highways sector to split project costs and risks between the government and the private builder. The Committee had earlier given in principle approval to the same projects under the Design, Build, Finance, Operate and Transfer (DBFOT) model, and switched to the Hybrid Annuity Model after market feedback. The tension is that attracting private capital required Indian Railways to keep the traffic and tariff risk on its own books, so the financing burden moves. The demand risk does not move with it.

    How does the Hybrid Annuity Model work here?

    1. The construction cost is split: Indian Railways pays 40 percent of the bid project cost as a grant during the construction period. The private party finances the remaining 60 percent.
    2. Repayment begins after commissioning: Once the line is operational, Indian Railways repays the private party’s 60 percent through annuity instalments, plus interest on the annuity.
    3. Maintenance is paid separately: Indian Railways also makes regular payments to the concessionaire for maintenance of stations, tracks and other assets.
    4. Operations stay public: Indian Railways operates the trains and collects all freight revenue.

    Which lines were cleared and what will they carry?

    1. Four of the six lines are in Odisha: These are the 49.58 km Balaram-Putgadia-Tentuloi inner corridor, the 112.56 km Budhapank-Tentuloi-Luburi outer corridor, the 101.26 km Jajpur-Keonjhar Road-Aradi-Dhamara Port line, and the 48.96 km line from Tikiri Station to the Waltair bauxite mines.
    2. Telangana carries the longest line: The 207.80 km Manuguru to Ramagundam line is the single largest of the six.
    3. Jharkhand carries the sixth: The 126.52 km Pakur to Godda line completes the set.
    4. Coal dominates the freight mix: The key commodities on these routes are primarily coal, along with iron ore, bauxite, coke, chemical manure, cement and food grains.

    What does the switch away from DBFOT change?

    1. Risk allocation moved to the public side: The Ministry of Railways would bear the traffic and tariff risks under the proposed structure, per the minutes of the Committee meeting held on 1 August.
    2. The private party is insulated from demand shortfalls: If freight loading or revenue falls below target, the private party is not penalised.
    3. Bid conditions remain to be fixed: The request for proposal will specify the minimum tenure of the agreement, the roles of the engineering, procurement and construction contractor, and the circumstances in which such arrangements are permitted.

    What is the money and the sequence?

    1. Two cost figures govern the projects: The total bid project cost of the six lines is Rs 15,976 crore, and the total capital cost covering the entire concession period is Rs 40,866 crore.
    2. The concession runs 17 to 19 years: That period covers construction, operation and the annuity repayments.
    3. Approval is not yet final: The projects go to the Union Cabinet before bids are invited.
    4. The build starts at the end of the decade: Bidding is expected in the 2027-28 financial year and construction of all six projects is proposed to commence from April 2028.

    Where does this sit in the Railways’ private investment record?

    1. Completed projects are modest in value: 18 projects worth Rs 16,686 crore have been completed through the public private partnership model in Indian Railways.
    2. Seven are under implementation: These are worth Rs 16,362 crore and include coal and port connectivity projects.
    3. The pipeline is far larger than the record: 49 other projects, costing around Rs 1.80 lakh crore, await execution under the partnership mode.
    4. The policy menu was widened deliberately: Indian Railways recently added the Hybrid Annuity Model and the Development Partner Model to its participative policy, to overcome financial bottlenecks and attract long term private capital.

    Challenges to the Hybrid Annuity Model in railways

    1. Annuity payments create long dated committed liabilities: Deferring 60 percent of the cost converts a capital expenditure decision into a fixed claim on operating revenue for nearly two decades. Eg. The National Highways Authority of India’s annuity and deferred payment obligations under its hybrid annuity projects have become a standing charge on its balance sheet. Fix. Publish a consolidated annuity liability statement alongside the Railway budget so the future claim is visible when the project is sanctioned.
    2. Freight demand is concentrated in a single commodity: Corridors built primarily for coal are exposed to a policy driven decline in thermal coal movement over the concession period. Eg. Coal accounts for roughly half of Indian Railways’ freight tonnage and a larger share of its freight earnings. Fix. Structure the corridors for multi commodity handling and terminal access rather than dedicated colliery to plant movement.
    3. Land acquisition and forest clearance drive the delay risk: Mineral corridors in Odisha and Jharkhand cross forest land and scheduled areas where consent and clearance timelines are unpredictable. Eg. Rail connectivity projects to mining belts have run past a decade waiting on forest clearance and rehabilitation settlements. Fix. Make financial closure conditional on prior possession of a defined share of the alignment, as the highways sector now requires.
    4. Dispute resolution has been the weak link in the highways precedent: Disagreements over cost variation, change of scope and delay attribution have taken years in arbitration. Eg. Arbitration claims against the highways authority have run into tens of thousands of crore rupees across concession disputes. Fix. Provide for a standing independent engineer with binding interim determinations written into the concession agreement.

    Conclusion

    The design question the model leaves open is whether shifting the financing burden to private balance sheets actually reduces the state’s exposure or merely reschedules it. Demand risk is retained on the public balance sheet either way. What to watch is the bid response once the Union Cabinet clears the projects and the request for proposal is issued, since the number of qualified bidders is the only real test of whether the risk split is priced as attractive.

    Back2Basics

    1. Location: It functions under the Department of Economic Affairs in the Ministry of Finance.
    2. Mandate: It appraises and approves central sector public private partnership projects above a specified cost threshold.
    3. Composition: It is chaired by the Secretary, Department of Economic Affairs, with the sponsoring ministry and the planning and legal departments represented.
    4. Process: It grants in principle approval at the project structuring stage and final approval before the project is placed before the Union Cabinet.

  • India, Kuwait hold inaugural key dialogue in Delhi to bolster defence ties

    Why in the News

    India and Kuwait held the inaugural meeting of the India-Kuwait Joint Defence Committee in New Delhi on August 28. Both sides agreed to expand bilateral defence cooperation across training, military exercises, industry, and research and development. The meeting operationalises the Memorandum of Understanding (MoU) on Defence Cooperation signed during Prime Minister Narendra Modi’s visit to Kuwait in December 2024.

    Why does an institutionalised defence dialogue with Kuwait matter for India?

    1. A first standing forum with a Gulf monarchy on defence: The Joint Defence Committee gives India and Kuwait a recurring institutional channel, rather than one-off visits, to advance training, joint exercises, defence industry links and research and development.
    2. Extends India’s Gulf defence footprint beyond energy ties: India’s engagement with the Gulf has historically centred on energy imports and the diaspora; a dedicated defence committee with Kuwait signals a broadening of the relationship into security cooperation, alongside similar frameworks India already runs with Saudi Arabia and the United Arab Emirates.
    3. Kuwait sits at a sensitive maritime chokepoint: Kuwait’s location near the head of the Persian Gulf and the Strait of Hormuz gives India a stake in the security of a route through which a large share of its crude oil imports transit.

    Challenges to the India-Kuwait defence relationship

    1. Limited defence-industrial base on the Kuwaiti side: Kuwait’s domestic defence manufacturing capacity is minimal, so cooperation is likely to stay import and training-oriented rather than co-production, unlike some of India’s other defence partnerships. Eg. India’s co-production discussions with the United States on the Javelin missile system have no current parallel in the Kuwait relationship. Fix. Use the Joint Defence Committee’s industry track to identify smaller co-development areas, such as maintenance, repair and overhaul services, where Kuwait’s capacity constraints are less binding.
    2. Competing suppliers already entrenched in the Gulf: Gulf states, including Kuwait, have longstanding defence procurement relationships with the United States, the United Kingdom and France, which limits the near-term scope for India to secure large equipment sales. Eg. Kuwait’s air defence and fighter fleets are built around US and European platforms, leaving India’s defence exports pitch centred on niche systems and services rather than big-ticket sales.

    Conclusion

    The inaugural Joint Defence Committee meeting converts the 2024 MoU into a standing institutional mechanism, marking a modest but concrete step in India’s effort to deepen security ties with the Gulf beyond energy and trade. The substantive test will be whether the committee produces actual joint exercises, training exchanges or industry tie-ups before its next meeting.

    What is the Gulf Cooperation Council (GCC)?

    1. A regional grouping, not Kuwait’s own body: The Gulf Cooperation Council is a political and economic union of six Gulf Arab states, Kuwait, Saudi Arabia, the UAE, Qatar, Bahrain and Oman, formed in 1981 to coordinate economic, security and foreign policy matters among them.
    2. India engages the GCC bilaterally, not as a bloc: India does not have a defence framework with the GCC as a single entity; agreements such as the Joint Defence Committee are negotiated bilaterally with individual member states like Kuwait.

  • FCNR(B) deposits push forex reserves to all-time high of $729 bn in August

    Why in the News

    The Reserve Bank of India’s concessional swap window for Foreign Currency Non-Resident (Bank), or FCNR(B), deposits has propelled India’s foreign exchange reserves to a record $729.33 billion as of 21 August, surpassing the previous all-time high of $728.49 billion recorded on 27 February, just a day before the United States and Israel struck Iran and touched off the West Asia conflict that drove global energy prices sharply higher. Reserves rose by $12.42 billion in the week ended 21 August alone, with FCNR(B) inflows of $65.4 billion accounting for most of the $72.85 billion that has entered India since three concessional swap windows opened on 8 June.

    What is driving reserves to a record, and what does the FCNR(B) window actually do?

    1. Scale of inflows: FCNR(B) deposits outstanding rose from $34.04 billion at the end of May to $65.4 billion by 21 August, since the window opened on 8 June, and reserves themselves jumped $12.42 billion in the week ended 21 August.
    2. Mechanism: Under the FCNR(B) scheme the central bank bears the full exchange rate risk on these non-resident deposits, since the money is held in foreign currency rather than converted into rupees, which let banks offer interest rates as high as 7.4 percent.
    3. Leveraged NRI participation: Non-resident Indians have also borrowed at lower interest rates abroad to deposit the proceeds into FCNR(B) accounts, earning returns of as much as 15 percent on the resulting spread.

    Why did reserves need rebuilding in the first place?

    1. The rupee was already under stress before the record: The rupee came under intense pressure from large foreign portfolio outflows, with $19 billion leaving Indian markets in 2025 and a further $24 billion in the first five months of 2026, pushing the currency to near 97 per dollar in mid-May.
    2. The West Asia conflict added an oil import shock: Since roughly 85 percent of India’s crude oil needs are met through imports, the conflict’s closure-driven spike in global energy prices raised the country’s import bill and added further pressure on the rupee just as reserves were near their earlier February high.
    3. The rupee remains down year-on-year despite the record reserves: The rupee closed at 95.39 per dollar on Friday, little changed from its 95.79 level on 4 June and still 8.1 percent weaker than a year earlier, showing the reserve build has stabilised rather than reversed the currency’s decline.

    What other measures accompanied the FCNR(B) window?

    1. Two additional swap windows: Announced alongside FCNR(B) on 5 June, swap facilities for Overseas Foreign Currency Borrowings and External Commercial Borrowings have together brought in $4.86 billion and $2.59 billion respectively since 8 June.
    2. Tax relief for foreign portfolio investors: The government removed capital gains and withholding taxes on foreign portfolio investment in government securities as part of the same package meant to pull in capital and support the rupee.
    3. An accelerated closure timeline: Because inflows arrived faster than expected, the RBI moved the FCNR(B) window’s closing date to 31 August, a month earlier than the originally announced 30 September deadline.

    Challenges to relying on FCNR(B)-driven reserve accumulation

    1. Weak currency response relative to precedent: The rupee has barely moved during this swap window, compared with the 2013 episode when the rupee rose 10.3 percent, from 67.6 to 61.3 per dollar, in the first 40 days after the RBI’s then-Governor introduced a similar FCNR(B) swap facility. Eg. The rupee moved from 95.79 to 95.39 per dollar between 4 June and 29 August this year, a fraction of the 2013 currency response to a comparable scheme. Fix. Pair reserve accumulation with structural measures that improve the current account, such as diversifying energy import sources, rather than treating swap-driven capital inflows alone as sufficient to support the currency.
    2. Reversal risk from leveraged hot money: A meaningful share of FCNR(B) inflows has been driven by non-resident Indians borrowing cheaply abroad to arbitrage into high-yield deposits, a flow that can reverse quickly once interest rate differentials narrow or the window closes. Eg. The window’s early closure on 31 August, a month ahead of schedule, was itself driven by inflows arriving faster than expected, which cuts both ways once the scheme ends and deposits mature. Fix. Stagger FCNR(B) maturities and monitor the redemption schedule closely to avoid a sudden reserve drawdown when large deposit tranches come due.

    Conclusion

    The FCNR(B) swap window has pushed India’s foreign exchange reserves past their previous February high to a record $729.33 billion, giving the Reserve Bank of India greater capacity to defend the rupee after a period of heavy foreign portfolio outflows and an oil price shock from the West Asia conflict. The rupee’s limited appreciation despite the record inflow, unlike the sharper rupee gains seen after the comparable 2013 swap window, signals the current build is cushioning rather than reversing currency pressure.

    Back2Basics: What are FCNR(B) deposits?

    1. FCNR(B) deposits are foreign currency accounts that non-resident Indians can hold with Indian banks, where the deposit and its returns stay denominated in the foreign currency rather than in rupees.
    2. The scheme shifts exchange rate risk onto the Reserve Bank of India rather than the depositor or the bank, which lets banks offer higher interest rates to attract inflows during periods of currency pressure.
    3. India last used a similar concessional FCNR(B) swap window in 2013, under then RBI Governor Raghuram Rajan, to stabilise the rupee following a sharp depreciation.

  • FM: Closer India-Canada economic ties important amid global uncertainty

    FM: Closer India-Canada economic ties important amid global uncertainty

    Why in the News

    The Union Finance Minister has said closer economic cooperation between India and Canada carries greater significance amid a rapidly changing global landscape marked by geopolitical uncertainty, and called for stronger partnerships to build resilient, sustainable and inclusive economies. The remarks came after the inaugural India Canada Economic and Financial Dialogue, the first such dialogue between the two countries. The Finance Minister said the dialogue reflects a shared ambition to move beyond traditional trade in goods and services toward a deeper partnership covering investment, finance, capital markets and regulatory cooperation.

    What is the India Canada Economic and Financial Dialogue?

    1. About: It is a bilateral mechanism between the Indian and Canadian finance ministries to coordinate on macroeconomic policy, financial sector cooperation and multilateral economic issues, launched with its inaugural round.
    2. Scope of discussions: The inaugural round covered three areas, macroeconomic developments and domestic policy priorities in both countries, avenues for financial sector cooperation, and broader international and multilateral cooperation on shared interests.
    3. Anchored in a wider strategic goal: The Prime Minister and his Canadian counterpart have set an ambitious goal for strengthening bilateral ties, and the dialogue is meant to give that goal fresh momentum and direction.

    What case did the Finance Minister make for closer India Canada cooperation?

    1. Global uncertainty is the backdrop: The Finance Minister described the world as going through a profound transformation with constantly evolving geopolitical and economic realities, making resilient partnerships more important.
    2. India’s economy was presented as a stable partner: The Finance Minister highlighted India’s “remarkable macroeconomic resilience” and pointed to complementarities between the two economies as grounds for expanding investment and economic cooperation.

    What specific areas of financial cooperation did the two sides identify?

    1. Cross border payments and financial stability: The two sides explored cooperation on cross border payment systems and measures to safeguard financial stability.
    2. Fintech and capital markets: Discussions also covered cooperation in financial technology and capital markets, part of the plan to move beyond goods and services trade into deeper financial integration.

    Conclusion

    The inaugural dialogue has set out macroeconomic policy coordination, financial sector cooperation and multilateral engagement as its three working areas. No date has been set for the next round, but the framework is intended to carry forward the broader bilateral goal the Prime Minister and his Canadian counterpart have set for the relationship.

    1. PSBs improved significantly: During 2014-15 to 2025-26, PSBs recorded average efficiency of 88.53%, compared with 85.62% for private banks. Foreign banks led over the full period: Foreign banks had the highest 12-year average of 88.98%, but their efficiency declined from 95.86% in 2014-15. Most efficient banks:
    2. HSBC and JPMorgan Chase: 100% efficiency in all 12 years.
    3. HDFC Bank: 97.54% average efficiency among private banks.
    4. State Bank of India (SBI): 97.49%, highest among PSBs.
    5. DBS Bank India: Lowest single-year efficiency of 40.12% in 2021-22, linked to its merger with Lakshmi Vilas Bank.
    6. Impact of PSB mergers: PSBs were relatively less efficient than private banks during FY2019 to FY2022, partly due to the merger and rationalisation of branches, employees and business operations.

    Data Envelopment Analysis (DEA)

    1. DEA is a method for measuring the relative efficiency of units, here banks, that produce the same kind of output from different combinations of inputs.
    2. An efficiency score below 100% means the unit could reduce its inputs by that shortfall and still produce the same output. Eg. A score of 85% means the unit could cut inputs by 15% without any loss of output.

  • Russia turns to India to meet petrol demand after oil infra takes a hit in Ukraine strikes

    Russia turns to India to meet petrol demand after oil infra takes a hit in Ukraine strikes

    Why in the News

    Repeated Ukrainian strikes on Russian oil refineries, combined with routine maintenance, strong summer demand and logistical bottlenecks, have cut Russia’s domestic petrol supply. Russia imported over one million barrels of petrol from India, mainly from Nayara Energy’s Vadinar refinery, over June and July 2026, according to ship tracking data.

    What does the trade data show?

    1. Rising volumes over two months: Gasoline exports from India to Russia rose from about 12,000 barrels per day in June 2026 to about 21,000 barrels per day in July 2026, together close to a million barrels, with the trend reported to have continued into August.
    2. Vadinar as the main Indian source: Three cargoes of around 320,000 to 350,000 barrels each were shipped to Russia from the Vadinar refinery, which has significant Russian shareholding. Additional volumes may have reached Russia through ship-to-ship transfers and vessels with undeclared destinations.
    3. Belarus and Kazakhstan remain the largest suppliers: Most of Russia’s imported gasoline still comes from Belarus, where one of two refineries is 42% owned by a Russian consortium and processes only Russian crude. Kazakhstan is a net petrol importer itself and cannot supply large volumes.
    4. Russia has restricted its own exports to protect domestic supply: Moscow has curbed diesel exports ahead of winter and placed volume limits on petrol sold per vehicle at fuel stations in several regions, since its refining system produces a comfortable diesel surplus but only a thin petrol buffer over domestic demand.

    Why does this mark a reversal in the India-Russia energy relationship?

    1. India’s established role has been as buyer, not supplier: Russian crude, discounted after Western sanctions cut off Moscow’s traditional European buyers following its invasion of Ukraine, now makes up the largest share of India’s crude import basket.
    2. The new flow runs in the opposite direction: India is now supplying a refined product back to Russia, derived in part from the same Russian crude it imports, a flow that did not exist before June 2026.

    Petrol vs Diesel Situation

    Petrol

    • More vulnerable to supply disruptions.
    • Domestic refinery output normally only slightly exceeds demand.
    • Russia has:
      • Restricted exports.
      • Limited petrol supplies at some fuel stations.
      • Adjusted product specifications to protect domestic availability.

    Diesel

    • Russia is relatively better supplied.
    • Its refining system produces more diesel than domestic consumption requires.
    • Nevertheless, Russia has also restricted diesel exports to build a cushion before winter.

    Why is India Important?

    • India has substantial refining capacity and exportable petroleum products.
    • Indian refineries continue to receive large quantities of Russian crude oil.
    • Some petrol exported to Russia may therefore be produced from Russian crude refined in India.
    • This creates an increasingly complex two-way India-Russia energy relationship.

    Conclusion

    The shift shows India’s refining capacity, especially at plants processing discounted Russian crude, has become a swing supplier for Russia’s own domestic fuel shortfall. Whether the flow continues depends on how quickly Russia can repair refining capacity damaged by continuing strikes.

  • Global space norms find a firm footing in India’s new re-entry rules

    Global space norms find a firm footing in India’s new re-entry rules

    Why in the News

    The Indian National Space Promotion and Authorisation Centre (IN-SPACe) has released India’s first guidelines on planned re-entry, requiring any Indian entity undertaking such a re-entry to obtain its authorisation, whether the re-entry occurs within or outside Indian territory.

    What is a planned re-entry?

    1. The defining test is intent and survivability: Objects designed to survive re-entry, or intentionally controlled towards a particular landing or impact area, require separate authorisation. This is what makes a re-entry planned.
    2. What falls outside the definition: Objects expected to burn up, melt or fragment sufficiently during natural orbital decay do not count as a planned re-entry.
    3. Why the distinction carries regulatory weight: The category separates a return that must be assessed and cleared in advance from one that requires no clearance, so the definition determines the reach of the entire framework.

    Why has re-entry become a governance problem now?

    1. The historical baseline was negligible: For many decades there were few rocket launches and few new satellites in orbit each year, so there were also few re-entries.
    2. The consequences used to be trivial: Most of those re-entries simply burned up in the atmosphere with little consequence.
    3. The orbital population has changed: Low-earth orbit, the band of orbits closest to the earth where most satellites operate, now hosts several thousand satellites, with private companies planning for many more.
    4. Deliberate de-orbiting has become routine: Satellite operators are also deliberately bringing satellites down at the end of their operational lives as part of post-mission disposal, in great numbers.
    5. The physical risks are specific: A spacecraft returning to the earth has to negotiate many risks, including deviating from its planned path and breaking up into smaller pieces.
    6. The risks cross jurisdictions: A returning object may affect airspace and maritime zones, and may potentially crash in the territory or jurisdiction of another state, which makes re-entry a governance problem as well as a physics problem.

    What are the three important elements of the guidelines?

    1. Accountability: Any Indian entity undertaking a planned re-entry, whether within or outside Indian territory, now requires IN-SPACe authorisation.
    2. Foreign operators must route through an Indian entity: Non-Indian entities seeking to undertake planned re-entry over Indian territory must route the activity through an Indian-incorporated entity, such as a subsidiary, joint venture or partnership.
    3. The Indian entity carries the compliance duty: That Indian entity is responsible for complying with Indian laws, regulations and national security requirements.
    4. Why the accountability gap exists: Commercialisation separates ownership from consequence, since the spacecraft may belong to a private company and the effects of its return lie across maritime zones and jurisdictions. India has responded by attaching regulatory responsibility to a re-entering entity before the risk materialises.
    5. Risk must be acceptable: The expected casualty risk must remain below 1 in 10,000, supported by survivability and ground-casualty assessments.
    6. Failure scenarios must be modelled and shared: Operators have to analyse and share failure scenarios, fragmentation patterns, ballistic coefficients, de-orbit plans, flight-path angles and danger zones.
    7. Surviving and hazardous components must be identified: They must identify components likely to survive re-entry, and hazardous systems such as batteries and pressure vessels.
    8. A number makes sustainability measurable: By requiring quantitative studies and attaching a figure to the acceptable risk threshold, the guidelines make sustainability measurable and therefore trackable.
    9. Permissions: IN-SPACe will re-verify the latest re-entry parameters approximately three months before the proposed operation.
    10. A post-launch decision needs six months’ notice: If a planned re-entry is decided upon after launch, the operator must apply at least six months in advance.
    11. Airspace and maritime warnings at 45 days: Operators must obtain an IN-SPACe advisory note to issue warnings to airborne and marine vessels in the re-entry area at least 45 days before the re-entry begins.
    12. A foreign jurisdiction requires that state’s clearance: If a re-entry site falls within the territorial control of a non-Indian state, including its exclusive economic zone, the applicant must submit the relevant clearance or authorisation from that state.
    13. The checkpoints are intervention windows: These checkpoints give the regulator fixed windows and mechanisms to intervene when re-entry parameters change after the mission has launched, or when the risk pattern changes.

    What international framework do the guidelines translate?

    1. The development period: For nearly two decades the international community has developed principles for sustainable space activities.
    2. The two leading instruments: They are the Inter-Agency Space Debris Coordination Committee’s Space Debris Mitigation Guidelines, and the Guidelines for the Long-term Sustainability of Outer Space Activities of the United Nations Committee for the Peaceful Uses of Outer Space.
    3. The treaty foundation: Article IX of the Outer Space Treaty 1967 provides an important foundation for environmental responsibility in the conduct of space activities.
    4. The working definition of sustainability: The UN Guidelines define sustainability as maintaining space activities while preserving the outer space environment for future generations.
    5. The structural weakness of that architecture: Most of the contemporary sustainability architecture works on guidelines and other similar forms of soft law, which operators are not obligated to follow.
    6. How the national regulator closes it: The IN-SPACe guidelines solve this problem for India by tying an operator’s fragmentation analysis and insurance policies to the national regulator, which converts a voluntary standard into a condition of permission.

    How do the guidelines handle liability?

    1. The treaty position on liability: The Space Liability Convention 1972 places absolute liability on a launching state for damage caused by its space object on the surface of the earth, or to aircraft in flight.
    2. The state carries the claim, not the operator: Absolute liability means the launching state answers for the damage regardless of fault, so a private failure becomes a sovereign liability by default.
    3. The guidelines invert that internally: Operators must undertake planned re-entries at their own risk, and they remain liable for third-party damage and claims.
    4. Indemnity to the government: Operators indemnify the Government of India and its agencies for liability incurred under India’s international commitments.
    5. Insurance as the backing: Operators must satisfy the applicable third-party insurance requirements, so the indemnity is funded rather than merely promised.

    Challenges to the IN-SPACe planned re-entry guidelines

    1. The regulator has no statutory backing: IN-SPACe functions as the sector’s regulator without legislative authority, so its guidelines rest on executive policy rather than on an Act. Eg. India has no dedicated space activities legislation, and the Indian Space Policy 2023 is a policy document. Fix. Enact a space activities law placing authorisation, liability and penalties on a statutory footing.
    2. The regulator sits inside the body it regulates: IN-SPACe authorises activities of private companies and government entities including ISRO, and it operates under the Department of Space. Eg. The same department is both the policy custodian and the parent of the entity it must clear. Fix. Place IN-SPACe under an independent appointments and reporting structure, with appeals lying outside the Department of Space.
    3. No appellate route for a refused authorisation: An operator refused authorisation, or held to a risk finding it disputes, has no defined appeal forum. Eg. The guidelines fix a casualty risk threshold without naming any forum before which an operator may contest a risk finding. Fix. Constitute a space disputes appellate tribunal with technical members, on the model used for telecom and electricity regulation.
    4. Verification capacity lags the requirement: A casualty risk below 1 in 10,000 must be independently verifiable, and that requires tracking and modelling capability the regulator does not itself hold. Eg. Debris tracking rests on ISRO’s Project NETRA, which is oriented to collision avoidance rather than to re-entry survivability audit. Fix. Build an independent re-entry analysis cell with access to radar and optical tracking data, empanelling accredited third-party assessors.
    5. Insurance capacity is untested at Indian scale: Third-party space insurance is a thin market, and a small operator may be unable to price cover for a low-probability, high-consequence event. Eg. Indian space startups have grown from a handful to around 200, most of them without balance sheets that carry catastrophic risk. Fix. Create a graded liability cap with a government-backed pool above it, on the model used for civil nuclear liability.

  • China lands a rocket first stage for the first time with Zhuque-3

    Why in the News

    China has recovered the first stage of a rocket on land for the first time, using the reusable rocket Zhuque-3, which was launched on Wednesday morning. It is the country’s second rocket stage recovery overall, after a sea platform recovery in July, and the first to use deployable landing legs. State media described the result as a major breakthrough in the country’s reusable rocket technology.

    What is a reusable rocket?

    1. About: A reusable rocket is a launch vehicle whose stages are recovered intact after flight and flown again, instead of being discarded once the payload is delivered.
    2. Why it lowers cost: The first stage carries most of the engines and structure, so recovering it avoids rebuilding the most expensive part of the vehicle for every launch.
    3. How recovery works: The stage separates after boost, reorients, uses engine burns to slow its descent and lands vertically on a pad or on a sea platform.
    4. What landing legs add: Deployable landing legs stabilise the stage at touchdown on ground, which is why their first use is treated as a distinct technical milestone.

    What did the Zhuque-3 flight achieve?

    1. Launch and recovery: Zhuque-3 was launched on Wednesday morning and its first stage was recovered afterward.
    2. First on land: This marks China’s first successful recovery of a rocket first stage on land.
    3. Second overall: It is the second time the country has recovered a rocket stage, following a successful recovery on a sea platform in July.
    4. New hardware: The recovery marked China’s first use of deployable landing legs.
    5. Official assessment: The state news agency deemed the result a major breakthrough in the country’s reusable rocket technology.

    How does this compare with earlier recoveries?

    1. China’s July recovery: On 10 July, the first stage of a Long March-10B rocket separated from the second stage after lift off and returned to a platform at sea.
    2. The difference land makes: A sea platform recovery avoids overflight of populated areas, while a land recovery removes the need for a recovery vessel and shortens the turnaround.
    3. United States, SpaceX: SpaceX has been recovering rockets since 2015 and has driven down launch costs by reusing hardware that would otherwise be discarded after carrying satellites and other payloads toward space.
    4. United States, Blue Origin: Blue Origin has likewise been recovering boosters since 2015, establishing vertical landing as a repeatable rather than experimental technique.
    5. What the comparison shows: China is closing a capability gap that has stood for a decade, and the operator here is a private launch company rather than the state programme.

    Why does reusability decide launch economics?

    1. Cost per launch: Reuse spreads the cost of building a stage across several flights, which is the single largest lever on the price of access to orbit.
    2. Launch cadence: Recovery shortens the interval between flights, which matters for deploying large satellite constellations.
    3. The payload penalty: Propellant reserved for the landing burn and the mass of legs and grid fins reduce the payload the same vehicle can carry.
    4. The break even condition: Reuse pays only when the same stage flies many times, so refurbishment cost and inspection time determine whether the saving is real.
    5. Strategic consequence: Cheaper and more frequent launch capacity translates directly into faster deployment of communication, navigation and remote sensing assets.

    Conclusion

    Zhuque-3’s flight gives China its first land recovery of a rocket first stage and its second stage recovery in six weeks, after the Long March-10B sea platform recovery of 10 July. The flight also carried the country’s first use of deployable landing legs, which is the hardware element that makes routine ground landings possible. The state news agency has called it a major breakthrough in reusable rocket technology. The next measure of the achievement is whether the recovered stage is refurbished and reflown, since recovery without reflight does not deliver the cost saving that reusability exists to produce.
