  • Long overdue: On coal exchanges 

    Why in the News?

    India has unveiled the Coal Exchange Rules, 2026, marking a major structural reform in the coal sector. For the first time, coal will be traded through regulated exchange platforms similar to power exchanges

    What are the Coal Exchange Rules, 2026?

    The Coal Exchange Rules, 2026, notified by the Ministry of Coal, establish a legally binding framework for transparent, electronic “many-to-many” spot mineral trading. Regulated by the Coal Controller Organisation, the rules aim to improve price discovery and market access for consumers.

    Key Features of the Rules

    1. Electronic Trading: The system transitions coal marketing from the traditional “one-to-many” bilateral model to an efficient, competitive digital trading platform where multiple buyers and sellers can transact.
    2. Mandatory Physical Delivery: All transactions must culminate in physical delivery of the coal. These are supported by independent quality verification to ensure contractual compliance.
    3. Regulatory Oversight: The Coal Controller Organisation acts as the central market regulator, handling the registration, supervision, and auditing of exchanges, as well as enforcing safeguards against market manipulation.
    4. Registration Validity: Eligible entities (incorporated as companies under the Companies Act, 2013) are granted authorizations to establish and operate exchanges for 25 years.
    5. Financial Obligations: Operators pay a ₹50 Lakh one-time registration fee, a ₹3 Lakh application fee, and an annual fee calculated as either ₹30 Lakh or 0.02% of the total trading volume, capped at ₹5 Crore.

    How can coal exchanges transform India’s coal market structure?

    1. Market-Based Trading: Establishes regulated platforms for buying and selling coal through transparent mechanisms.
    2. Price Discovery: Creates market-driven price signals instead of relying primarily on bilateral negotiations.
    3. Transparency: Reduces opacity associated with traditional contractual arrangements.
    4. Competition: Enables broader participation by producers and consumers.
    5. Secondary Markets: Facilitates development of coal trading beyond primary allocation channels.

    Why is the existing coal allocation mechanism considered inadequate?

    1. Long-Term Contracts: Most coal transactions currently occur through long-duration agreements, particularly for the power sector.
    2. Auction Dependence: Significant volumes are allocated through auctions where prices may rise substantially.
    3. Coal India Dominance: Non-regulated consumers often depend on Coal India auctions.
    4. Premium Pricing: Coal is frequently sold at premiums to the highest bidder.
    5. Limited Market Signals: Existing mechanisms provide inadequate real-time information regarding shortages and surpluses.

    What lessons can be drawn from India’s power exchange experience?

    1. Market Signalling: Power exchanges evolved into indicators of scarcity and surplus conditions.
    2. Balancing Function: Initially addressed short-term shortages before becoming broader market institutions.
    3. Reference Prices: Spot prices emerged as benchmarks for the wider power market.
    4. Enhanced Efficiency: Improved resource allocation without replacing long-term Power Purchase Agreements (PPAs).
    5. System Stress Indicator: Exchange prices increasingly reflected grid conditions and demand-supply imbalances.

    Can coal exchanges help balance regional shortages and surpluses?

    1. Inventory Utilisation: Enables idle or surplus coal stocks to be traded efficiently.
    2. Regional Balancing: Allows coal-deficit regions to access supplies from surplus areas.
    3. Supply Optimization: Improves allocation without requiring additional production.
    4. Resource Efficiency: Maximizes utilization of existing inventories.
    5. Market Liquidity: Encourages continuous trading and availability.

    What challenges could limit the success of coal exchanges?

    1. Quality Variation: Coal quality differs significantly across grades and mines.
    2. Non-Fungibility: Unlike electricity, coal is not a uniform commodity.
    3. Standardisation Requirement: Requires robust quality certification mechanisms.
    4. Contract Enforcement: Strong dispute resolution and enforcement systems are necessary.
    5. Liquidity Constraints: Exchanges require adequate trading volume to remain viable.

    What logistical challenges could constrain coal exchanges?

    1. Railway Dependence: Coal transportation relies heavily on railway infrastructure.
    2. Last-Mile Connectivity: Mine-to-consumer logistics remain uneven across regions.
    3. Freight Costs: Transportation costs can significantly influence final coal prices.
    4. Delivery Delays: Physical delivery constraints may reduce exchange efficiency.
    5. Infrastructure Gaps: Inadequate evacuation infrastructure may limit market integration.

    3. Price Benchmarking: Helps establish credible market reference prices.
    4. Supply Assurance: Supports reliability of exchange operations.
    5. Institutional Confidence: Enhances acceptance of the platform.

    Why should retail and smaller consumers be integrated into coal exchanges?

    1. Accessibility: Expands coal access beyond large industrial consumers.
    2. Competition: Reduces concentration of market power.
    3. Inclusiveness: Facilitates participation of smaller industries.
    4. Price Transparency: Provides equal access to market information.
    5. Market Expansion: Increases overall trading activity.

    What institutional safeguards are required for successful implementation?

    1. Volatility Management: Ensures protection against excessive price fluctuations.
    2. Dispute Resolution: Provides mechanisms for conflict settlement.
    3. Logistics Integration: Strengthens transportation and delivery systems.
    4. Regulatory Oversight: Ensures compliance and market integrity.
    5. Settlement Systems: Facilitates efficient trading and delivery.

    Conclusion

    The Coal Exchange Rules, 2026 represent a shift from administrative allocation towards market-based coal governance. Their success will depend on quality standardisation, liquidity creation, Coal India’s participation, efficient logistics, and strong regulatory oversight.

  • Zojila Tunnel: The challenge of digging through the Himalays

    Why in the news?

    The near-completion breakthrough of the Zojila Tunnel, being constructed at an altitude of 11,578 feet, marks one of India’s most ambitious and technically demanding infrastructure achievements.

    What is the Zojila Tunnel?

    1. The Zojila Tunnel is a 13-km bi-directional road tunnel being constructed beneath the Zojila Pass in the Himalayas. 
    2. Located at an elevation of 11,578 feet, it aims to provide all-weather connectivity between Kashmir Valley and Ladakh. 
    3. The project is among India’s most challenging infrastructure undertakings due to the complex geological and environmental conditions associated with Himalayan terrain.

     How does Himalayan geology make tunnel construction exceptionally difficult?

    1. Young Fold Mountains: The Himalayas are geologically young and remain tectonically active, resulting in unstable rock formations.
    2. Variable Rock Strata: Rock composition can change within a few metres, creating unpredictable excavation conditions.
    3. Structural Weaknesses: Rock formations contain fractures, cracks, fault zones, and shear zones that reduce stability.
    4. Loose Geological Material: Engineers encounter loose rocks, boulders, and weak strata requiring different support systems.
    5. Ocean-Floor Origin: Himalayan rocks originated from uplifted seabed deposits, producing highly heterogeneous geological structures.
    FeatureYoung HimalayasOld Mountains (e.g., Aravallis)
    StabilityLowerHigher
    Tectonic ActivityActiveRelatively Stable
    Tunneling RiskHighLower
    Rock UniformityPoorBetter

    Why do altitude and climatic conditions increase construction risks?

    1. High Elevation: Construction occurs at approximately 11,578 feet, reducing worker efficiency and equipment performance.
    2. Extreme Cold: Temperatures may fall to -30°C.
    3. Harsh Winters: Severe weather limits construction windows.
    4. Avalanche Threats: Snow avalanches create risks for workers and infrastructure.
    5. Operational Challenges: Combustion engines and heavy machinery experience reduced efficiency at high altitude.

    Why is water ingress one of the biggest engineering challenges in the Himalayas?

    1. Stored Water Reservoirs: Mountains contain large volumes of groundwater trapped within rock layers.
    2. Snowmelt Contribution: Melting snow continuously adds to underground water systems.
    3. Water Ingress: Excavation frequently intersects water-bearing zones.
    4. Hydrostatic Pressure: Excessive water pressure can destabilize tunnel structures.
    5. Flooding Risk: Uncontrolled seepage may trigger tunnel flooding and structural failures.

    Striking Observation

    1. Massive Water Storage: Geological assessments indicate that Himalayan mountains may contain water volumes comparable to an “ocean’s worth” of stored water.

    Why are shear zones and tectonic stresses particularly dangerous?

    1. Shear Zones: High-strain zones create instability during excavation.
    2. Rock Deformation: Tectonic pressure continuously alters stress distribution.
    3. Collapse Risk: Excavation may trigger localized failures in weak zones.
    4. Dynamic Conditions: Geological conditions often change unexpectedly during drilling.
    5. Engineering Uncertainty: Tunnel design frequently requires real-time modification.

    What safety measures were adopted during the Zojila Tunnel project?

    1. Ventilation Infrastructure: Three shafts were constructed along the tunnel length.
    2. Emergency Response: Shafts provide access for rescue and evacuation operations.
    3. Deep Access Shafts: The first shaft is 474.3 m deep, making it the deepest in India.
    4. Additional Shafts: The second shaft is 367.5 m deep, while the third shaft is 213.5 m deep.
    5. Operational Safety: Ventilation systems ensure worker safety during construction and future operation.

    How does the New Austrian Tunnelling Method (NATM) help overcome Himalayan challenges?

    The New Austrian Tunneling Method (NATM) is a modern, observational tunneling approach that reinforces the surrounding rock or soil, allowing it to deform slightly and become part of the tunnel’s primary load-bearing structure.

    1. Selective Excavation: Facilitates controlled blasting based on rock conditions.
    2. Sequential Construction: Excavation proceeds in stages rather than full-face excavation.
    3. Top-Heading Method: Upper tunnel section is excavated first, followed by the lower section.
    4. Adaptive Design: Allows modifications according to changing geological conditions.
    5. Risk Reduction: Enhances stability in weak and variable rock formations.

    About the NATM

    Principle: “The surrounding rock mass itself becomes part of the support system.”

    Key Components

    1. Shotcrete: Sprayed concrete for immediate stabilization.
    2. Rock Bolts: Reinforce fractured rock.
    3. Monitoring Systems: Continuous assessment of rock behaviour.
    4. Flexible Design: Engineering response adjusted to site conditions.

    How are water and structural stability managed during excavation?

    1. Drainage Pipes: Facilitate controlled water discharge.
    2. Pressure Management: Prevents buildup of hydrostatic pressure.
    3. Rock Bolting: Stabilizes fractured rock masses.
    4. Shotcrete Lining: Binds loose rock surfaces.
    5. Alignment Modification: Tunnel route can be altered to bypass weak geological sections.
    6. Site-Specific Design: Tunnel shape and support configuration vary according to local conditions.

    Why does the Zojila Tunnel have strategic significance beyond engineering?

    1. All-Weather Connectivity: Reduces dependence on the seasonally closed Zojila Pass.
    2. Regional Integration: Strengthens connectivity between Kashmir and Ladakh.
    3. Defence Logistics: Improves movement of military personnel and supplies.
    4. Economic Development: Facilitates tourism, trade, and local livelihoods.
    5. National Infrastructure Capacity: Demonstrates India’s capability to execute mega-projects in difficult terrain.

  • The reality behind falling net FDI 

    Why in the News?

    India’s net FDI has witnessed an extraordinary collapse, falling from almost $44 billion in 2020-21 to less than $1 billion in 2024-25, even as gross FDI inflows recovered to $94.6 billion. This sharp divergence has reignited debate over whether India is becoming a less attractive investment destination. 

    Why has India’s net FDI declined so sharply despite strong gross inflows?

    1. Net FDI Measurement: Net FDI under the Balance of Payments (BoP) framework is calculated after adjusting gross inflows for FDI-related outflows.
    2. Sharp Decline: Net FDI fell from nearly $44.0 billion in 2020-21 to less than $1 billion in 2024-25.
    3. Strong Gross Inflows: Gross FDI inflows recovered to $94.6 billion in 2025-26.
    4. Misleading Interpretation: Weak net FDI is often interpreted as a sign of declining investor confidence, while strong gross inflows are presented as evidence of economic strength.
    5. Underlying Reality: Both views overlook the changing composition of international capital flows and the mechanisms governing inflows and outflows.

    Does the conventional FDI debate overlook important structural changes?

    1. Incomplete Narrative: Public discourse focuses primarily on aggregate FDI numbers rather than the nature of investments.
    2. Changing Policy Priorities: India’s post-1991 FDI policy initially emphasised technology acquisition, export promotion, and foreign exchange conservation.
    3. Shift in Focus: Policy gradually prioritised attracting larger inflows, while concerns regarding future external payment obligations and investment quality received less attention.
    4. Need for Assessment: Evaluating FDI requires examining investor categories, sectoral allocation, and associated outflows rather than focusing solely on inflow volumes.

    What types of FDI are entering India and how do they differ in developmental impact?

    Traditional or Real FDI

    1. Source: Multinational enterprises investing directly in production and services.
    2. Contribution: Brings technology, brands, managerial capabilities, and production know-how.
    3. Impact: Supports long-term industrial development and employment generation.

    Financial Investor FDI

    1. Source: Private equity funds, venture capital funds, sovereign wealth funds, and asset managers.
    2. Objective: Capital appreciation rather than production expansion.
    3. Impact: Provides financial capital but contributes less to technology transfer and industrial capacity creation.

    Diaspora and SPV-Based Investments

    1. Mechanism: Capital raised abroad and channelled through offshore financial centres.
    2. Instrument: Special Purpose Vehicles (SPVs).
    3. Characteristic: Frequently associated with round-tripping of domestic funds.

    How has the composition of FDI changed in recent years?

    1. Real FDI Share: Accounted for only 41.9% of effective inflows between 2022-23 and 2025-26.
    2. Financial Investor Share: Contributed 40.5% of effective inflows.
    3. Diaspora/SPV Share: Represented 17.6% of total inflows.
    4. Developmental Concern: A rising share of financial investors and SPVs reduces the developmental gains usually associated with traditional FDI.
    5. Technology Transfer: Becomes weaker when investments are motivated primarily by financial returns rather than production activity.

    Why do rising investor exits matter for understanding net FDI trends?

    1. Exit Signals: Business model of financial investors involves eventual exits through stake sales and disinvestment.
    2. Large Exit Example: Singapore’s Temasek exited Schneider Electric India in 2025.
    3. Scale of Exit: Exit generated approximately $6.4 billion.
    4. Initial Investment: Around $637 million invested in 2020.
    5. Return Multiple: Approximately 45 times the original investment.
    6. PE and VC Exits: Foreign private equity and venture capital investors accounted for around $29 billion in outflows.
    7. Implication: Such exits substantially increase capital outflows and depress net FDI.

    Are gross FDI figures overstating actual fresh capital entering India?

    1. Accounting Inclusion: Gross FDI statistics include intra-group ownership reorganisations.
    2. Mergers and Acquisitions: Included even when no fresh capital enters the country.
    3. Share Swaps: Recorded as FDI transactions despite limited resource transfer.
    4. ECB Conversions: Conversion of external commercial borrowings into equity inflates inflow figures.
    5. Blind Spot: Gross FDI figures often fail to distinguish between fresh investment and accounting transactions.
    6. Illustrative Example: Large transactions involving Bosch and Mesee Technologies can significantly influence sectoral trends without necessarily bringing new productive capital.

    Why can high gross FDI figures create a misleading picture of investment performance?

    1. Gross FDI Recovery: Gross FDI inflows recovered to $94.6 billion, often cited as evidence of India’s continued attractiveness to foreign investors.
    2. Accounting Transactions: Gross FDI statistics include intra-group ownership restructuring, mergers and acquisitions, share swaps, and conversion of external commercial borrowings (ECBs) into equity.
    3. Limited Fresh Capital: Such transactions may alter ownership structures without necessarily bringing substantial new capital, technology, or productive capacity into the economy.
    4. Sectoral Distortions: Large corporate restructuring exercises can inflate FDI numbers and create an impression of strong investment activity in particular sectors.
    5. Developmental Concern: High gross inflows do not automatically translate into employment generation, manufacturing expansion, technology transfer, or export competitiveness.

    Why is the decline in manufacturing FDI a major concern?

    1. Four-Year Decline: Manufacturing FDI has fallen continuously for four consecutive years.
    2. Low Share: Manufacturing accounted for only 10.6% of total effective inflows during the latest four-year period.
    3. Industrial Consequences: Lower manufacturing investment weakens technology absorption and productive capacity creation.
    4. Employment Implications: Reduces potential for large-scale job creation.
    5. Strategic Concern: Limits India’s ambition to become a major global manufacturing hub.

    Does rising outward FDI represent globalisation or capital flight?

    1. Rapid Growth: India’s outward FDI has increased significantly.
    2. Sectoral Concentration: Around 45% of outward investments during 2023-24 to 2025-26 flowed into financial services, insurance, and business services.
    3. Destination Pattern: Singapore and the UAE accounted for approximately 27% and 11% respectively.
    4. Corporate Example: Tata Motors-owned subsidiary in Singapore invested $405 million to acquire IVECO Group in Italy.
    5. GIFT City Link: FDI routed through GIFT City increased from $246 million in 2023-24 to $1.8 billion in 2025-26.
    6. Extended Route: Total inflows and outward FDI through this channel reached approximately $1.40 billion, indicating expanding two-way flows.
    7. Dual Interpretation: Outward FDI may indicate both global expansion of Indian firms and relocation of capital across jurisdictions.

    How are FDI-related outflows reshaping India’s external sector?

    Disinvestment Outflows

    1. Magnitude: Disinvestment and capital withdrawals totalled approximately $178.9 billion.
    2. Drivers: Secondary sales, IPO exits, and share buybacks.

    Dividend Remittances

    1. Amount: Reached $118.9 billion.
    2. Source: Profits paid by multinational subsidiaries and affiliates, excluding reinvested earnings.

    Intellectual Property Payments

    1. Amount: Totalled $46.6 billion.
    2. Nature: Payments for intellectual property and royalty use.
    3. Estimated Allocation: Around 75% of total IPR payments assumed to be attributable to multinational subsidiaries and affiliates.

    Technical and Service Payments

    1. Amount: Around $250 billion transferred through technical and service/consultancy payments.
    2. Difficulty: Separation between foreign and domestic company payments remains challenging.

    Overall Outflows

    1. Adjusted Outflows: Even after excluding OFDI, technical service payments, dividends and IPR-related outflows, total outflows remained around $344.4 billion.
    2. Deteriorating Ratio: For every dollar of fresh inflow (excluding reinvested earnings), approximately $1.50 flowed out.
    3. Historical Comparison: Outflow per dollar of inflow rose from 56 cents (2014-15 to 2017-18) to 70 cents (2018-19 to 2021-22) before reaching the current high.

    Why should policymakers focus on the quality rather than the quantity of FDI?

    1. Technology Transfer: Real FDI contributes more effectively to technological upgrading.
    2. Industrial Development: Manufacturing-oriented FDI strengthens domestic production capabilities.
    3. External Sustainability: Excessive dependence on financial investors increases future outflow obligations.
    4. Investor Diversity: Different investor categories generate different developmental outcomes.
    5. Policy Evaluation: FDI performance should be assessed through technology gains, industrial capacity creation, employment generation, and external-sector implications rather than gross inflow figures alone.
    6. Core Message: Headline FDI numbers conceal important changes in investor composition, entry modes, exit strategies, and developmental impact.

    Conclusion

    India’s falling net FDI highlights that the quality and composition of foreign investment matter more than headline inflow numbers. Rising disinvestment, profit repatriation, and financial-investor-led flows have weakened net inflows despite strong gross FDI. Going forward, policy must prioritise productive, technology-intensive, and manufacturing-oriented FDI that strengthens industrial growth and external sector sustainability.
