Supreme Court’s Revival of Sedition Trials
Why in News?
The Supreme Court of India clarified in Kamran v. State of Madhya Pradesh (2026) that proceedings under Section 124A IPC (Sedition) may continue if the accused voluntarily consents, partially modifying the protective freeze imposed in S.G. Vombatkere v. Union of India (2022).

Practice Question
“The sedition debate in India reflects the constitutional tension between national security and democratic dissent.” Examine in light of recent Supreme Court developments and Section 152 of the Bharatiya Nyaya Sanhita. (250 words)
Issue in Brief
Limited Revival of Sedition Proceedings
The Supreme Court clarified that pending sedition-related trials and appeals can proceed only if the accused explicitly consents, ensuring that the 2022 freeze under Section 124A IPC does not unintentionally prolong incarceration or delay appellate relief.
Accused-Centric Clarification
The clarification emerged from cases where prolonged suspension of proceedings harmed accused persons awaiting appeals or bail, especially in multi-charge prosecutions involving sedition alongside offences under the Unlawful Activities (Prevention) Act and Arms Act.
Constitutional Uncertainty Continues
The constitutional validity of Section 124A remains unresolved and is pending before a proposed seven-judge Constitution Bench, while challenges to Section 152 of the Bharatiya Nyaya Sanhita (BNS), 2023 have now become the new focal point.
What is Sedition?
Section 124A IPC
Section 124A criminalised words, signs, representations, or acts that brought or attempted to bring hatred, contempt, or disaffection against the government established by law, carrying punishment up to life imprisonment.
Colonial Origins
The provision was introduced in 1890 by the British colonial administration primarily to suppress nationalist dissent, political mobilisation, and anti-colonial movements challenging imperial authority in India.
Use Against Freedom Fighters
Sedition was extensively used against leaders such as:
Bal Gangadhar Tilak
Mahatma Gandhi
with Gandhi famously describing sedition as the “prince among political sections” designed to suppress liberty.
Landmark Judicial Developments
Kedar Nath Singh v. State of Bihar (1962)
The Supreme Court upheld Section 124A constitutionally but restricted its application only to speech involving:
Incitement to violence
Public disorder
Threats to State security
thereby protecting legitimate criticism of government policies.
Balwant Singh v. State of Punjab (1995)
The Court ruled that casual anti-national slogans without resulting violence or public disorder do not amount to sedition, reinforcing protection for political speech under Article 19(1)(a).
S.G. Vombatkere v. Union of India (2022)
The Supreme Court kept Section 124A in abeyance, directing:
No new FIRs
No ongoing investigations
No coercive measures
Suspension of pending proceedings
while the Union reconsidered the colonial-era provision.
Why the 2026 Clarification Matters
Preventing Procedural Injustice
The blanket suspension imposed in 2022 unintentionally trapped several accused persons in prolonged detention because appeals, bail applications, and trials involving sedition could not progress despite urgent liberty concerns.
Example: Kamran Case
In the Kamran case, the accused reportedly remained incarcerated for nearly 17 years, with appellate proceedings stalled because sedition charges formed part of a broader conviction involving UAPA and Arms Act offences.
Shield, Not Shackle
The Court clarified that the 2022 order was intended as a protective shield against coercive prosecution, not as a procedural barrier preventing accused persons from pursuing acquittal, bail, or appellate remedies.
Key Constitutional Dimensions
Article 19(1)(a) – Freedom of Speech
Sedition directly affects the constitutional guarantee of free speech and expression because vague definitions of “disaffection” risk criminalising dissent, criticism, satire, journalism, and political opposition.
Article 19(2) – Reasonable Restrictions
The State justifies sedition laws under reasonable restrictions relating to:
Sovereignty
Integrity
Public order
Security of the State
but proportionality remains constitutionally contested.
Article 21 – Personal Liberty
Prolonged trials, indefinite detention, and delayed appeals under sedition provisions raise serious concerns regarding:
Due process
Fair trial
Speedy justice
Human dignity.
Article 14 – Arbitrary State Action
Critics argue that vague sedition provisions permit arbitrary police action and selective targeting of dissenters, potentially violating equality before law and non-arbitrariness principles under Article 14.
Transition from IPC to BNS
Repeal of Section 124A
With the enactment of the Bharatiya Nyaya Sanhita, the term “sedition” was formally removed from statutory language, signalling an attempt to distance the law from its colonial legacy.
Introduction of Section 152 BNS
Section 152 criminalises acts endangering:
Sovereignty
Unity
Integrity of India
including secessionist, subversive, or armed rebellion-related activities.
Expanded Scope Concerns
Critics argue Section 152 may actually broaden State powers because it includes:
Electronic communication
Financial means
Visible representations
Other undefined activities
potentially expanding prosecutorial discretion.
Major Concerns with Sedition Revival
Chilling Effect on Free Speech
Sedition laws can create a “chilling effect” where journalists, activists, students, academics, and opposition voices self-censor due to fear of criminal prosecution or prolonged legal harassment.
Questionable Nature of Consent
Critics argue consent by undertrials or prisoners may not always be truly voluntary because prolonged incarceration and desperation for relief may pressure accused persons into agreeing to proceedings.
Multi-Accused Complexity
The clarification does not fully address situations where:
One accused consents
Co-accused refuse
potentially leading to fragmented trials and inconsistent judicial outcomes.
Misuse by Law Enforcement
Sedition provisions have historically faced allegations of misuse for suppressing:
Political criticism
Peaceful protests
Student activism
Journalistic investigations.
National Security Perspective
State Security Concerns
Supporters argue India continues facing:
Separatism
Extremism
Insurgency
Radicalisation
Terrorism
requiring legal mechanisms protecting sovereignty and constitutional order.
Law Commission’s Position
The 22nd Law Commission recommended retaining sedition with safeguards, arguing repeal may force authorities to use even harsher counter-terror laws such as the Unlawful Activities (Prevention) Act.
Proposed Safeguards
The Commission suggested:
Mandatory preliminary inquiry
Approval before FIR registration
Explicit requirement of violence incitement
to reduce misuse while preserving national-security protection.
Governance and Criminal Justice Issues
Delayed Judicial Resolution
Despite years of litigation, the constitutional fate of sedition remains unresolved because the proposed seven-judge Constitution Bench has not yet been constituted by the Supreme Court.
Colonial Legacy Debate
Critics note that even the United Kingdom abolished sedition laws in 2009, questioning their compatibility with modern democratic constitutionalism.
Overcriminalisation Concerns
Broadly worded national-security laws risk normalising criminalisation of dissent, potentially weakening democratic accountability and constitutional culture in the long term.
Way Forward
Expedite Constitutional Adjudication
The Supreme Court should urgently constitute the proposed seven-judge bench to conclusively determine the constitutional validity of Section 124A and establish clear free-speech standards under modern constitutional jurisprudence.
Narrowly Define Section 152 BNS
Terms such as:
“Subversive activities”
“Separatist activities”
“Electronic communication”
must be narrowly and precisely defined to prevent arbitrary interpretation and misuse.
Strengthen Procedural Safeguards
Sedition-related prosecutions should require:
Senior-level approval
Preliminary judicial scrutiny
Evidence of violence incitement
Strict accountability for misuse.
Protect Democratic Dissent
Courts and legislatures must clearly distinguish between:
Criticism of government
Anti-State violence
ensuring democratic dissent remains protected under constitutional free-speech guarantees.
Police Sensitisation
Law-enforcement agencies require regular constitutional training to distinguish legitimate political expression from genuine threats to national sovereignty and public order.
Conclusion
Sedition in Constitutional Limbo
Section 124A currently occupies an unusual constitutional position: it is neither fully operational nor fully invalidated, remaining suspended, litigated, and selectively revivable at the instance of the accused.
Balancing Liberty and Security
India’s challenge lies in balancing:
National security
Sovereignty protection
Democratic dissent
Constitutional liberties
without permitting colonial-style criminalisation of political criticism.
Prelims Pointers
Section 124A IPC dealt with sedition and carried punishment up to life imprisonment.
Kedar Nath Singh v. State of Bihar (1962) upheld sedition but restricted it to incitement of violence or public disorder.
S.G. Vombatkere v. Union of India (2022) kept sedition proceedings in abeyance.
Section 152 of the Bharatiya Nyaya Sanhita (BNS), 2023 addresses acts threatening sovereignty, unity, and integrity of India.
The Supreme Court of India recently clarified that sedition proceedings may continue if the accused voluntarily consents.
Centre issues draft rules for VB-GRAMG
Why in News?
The Union Government released draft rules for the Viksit Bharat–Guarantee for Rozgar and Ajeevika Mission (VB-GRAMG) Act, 2025, which will replace the Mahatma Gandhi National Rural Employment Guarantee Act framework from July 1, 2026, fundamentally restructuring India’s rural employment architecture.

Practice Question
“The transition from MGNREGA to the VB-GRAMG framework reflects a shift from rights-based welfare to performance-linked rural employment governance.” Critically examine. (250 words)
Issue in Brief
Replacement of MGNREGA
The Centre officially notified that Mahatma Gandhi National Rural Employment Guarantee Act and associated schemes, guidelines, and notifications will cease from July 1, 2026, with VB-GRAMG becoming the new rural employment and livelihood framework.
New Funding Architecture
The draft rules introduce a “normative allocation” model linked to the 16th Finance Commission devolution criteria, replacing MGNREGA’s open-ended demand-driven funding structure with predetermined expenditure ceilings and performance-based allocations to States.
Public Consultation Process
The draft rules remain open for public comments for 30 days, after which the Centre may finalise implementation mechanisms governing rural employment guarantees, fund allocations, governance structures, and digital payment systems under the new framework.
About VB-GRAMG Act, 2025
Expanded Employment Guarantee
The VB-GRAMG Act increases guaranteed rural wage employment from 100 days to 125 days annually for rural households willing to undertake unskilled manual labour, while mandating wage payments within 15 days of completion of work.
Infrastructure-Focused Rural Development
The programme seeks to integrate employment generation with creation of durable rural infrastructure including:
Water conservation assets
Rural connectivity
Livelihood infrastructure
Climate-resilient public works.
Spatial and Digital Planning
The Act mandates preparation of Viksit Gram Panchayat Plans using geospatial technologies such as the Yuktdhara portal and integration with national planning systems including PM Gati Shakti.
Major Changes from MGNREGA
Shift from Demand-Driven to Normative Allocation
Unlike MGNREGA’s legally enforceable demand-based funding model, VB-GRAMG introduces predetermined “normative allocations” based on Finance Commission criteria, effectively converting central funding into a capped expenditure framework for States.
Revised Cost-Sharing Formula
Under the new framework, wage and programme costs will follow a:
60:40 Centre-State sharing ratio for most States
90:10 ratio for Northeastern and Himalayan States
unlike MGNREGA’s largely centralised wage funding structure.
State Liability Beyond Allocation
Any expenditure exceeding centrally determined normative allocations must reportedly be borne entirely by State governments, potentially increasing fiscal pressure on poorer States during periods of high rural distress or employment demand.
Funding Formula and Federal Dimensions
Strong Weightage to Income Distance
The allocation formula reportedly assigns:
42.5% weight to GSDP distance
17.5% weight to population
Remaining criteria carrying 10% weight each
thereby favouring relatively poorer and more populous States.
Priority to Economically Weaker States
The formula aims to direct larger allocations toward fiscally weaker States whose per-capita income remains substantially below wealthier States, reflecting broader equalisation principles used in Finance Commission devolution frameworks.
Fiscal Federalism Concerns
Critics argue that tying rural employment allocations to Finance Commission-style formulas may reduce flexibility and responsiveness during localised economic distress, droughts, migration crises, or sudden increases in rural unemployment demand.
Performance-Linked Funding
Conditional Central Allocations
From the second year onward, a portion of central allocations will reportedly depend upon State-level performance indicators such as:
Timely wage payments
Social audit compliance
Percentage of completed public works.
Incentivising Administrative Efficiency
The government argues that performance-linked funding may improve:
Transparency
Accountability
Asset quality
Administrative efficiency
while reducing leakages and implementation delays within rural employment programmes.
Risk of Penalising Weaker States
Experts caution that poorer States with weaker administrative capacity may receive lower allocations because of implementation constraints, thereby worsening regional inequalities in employment support and rural welfare outcomes.
Governance Structure under Draft Rules
National Level Steering Committee (NLSC)
The draft rules propose a 16-member National Level Steering Committee chaired by the Secretary, Department of Rural Development, to oversee implementation, allocation decisions, monitoring systems, and inter-ministerial coordination under the programme.
Composition of Committee
The committee includes officials from:
Panchayati Raj Ministry
Agriculture Ministry
Environment Ministry
Water Resources Ministry
NITI Aayog
National Informatics Centre
Five State governments.
Limited Civil Society Representation
Researchers and civil-society groups criticised the draft because the proposed Steering Committee reportedly excludes:
Workers’ unions
Community organisations
Civil society representatives
from direct implementation oversight mechanisms.
Social Audit and Participation Concerns
Reduced Participatory Governance
Critics argue that the new governance structure weakens the participatory and rights-based ethos of MGNREGA, which historically emphasised:
Gram Sabha participation
Social audits
Community oversight
Worker accountability mechanisms.
Contrast with Central GRG Council
Unlike the Steering Committee, the proposed Central Gramin Rozgar Guarantee Council reportedly includes representation from:
Panchayati Raj institutions
Workers’ organisations
SC/ST groups
Minorities
Persons with disabilities.
Centralisation Concerns
The draft rules reportedly allow the Union Government to alter the composition of the Steering Committee through notification without formal amendment procedures, raising concerns regarding excessive executive centralisation.
Technology and Digital Governance
Aadhaar-Based Payments
The draft rules emphasise:
Direct Benefit Transfer (DBT)
Aadhaar-based Payment Systems (APBS)
Management Information Systems (MIS)
for wage payments and unemployment allowances under the programme.
Digital Infrastructure Integration
The programme seeks to integrate:
Geospatial mapping
Digital monitoring
Asset tracking
Real-time reporting
into rural employment governance frameworks.
Inclusion Challenges
Excessive dependence on digital payment systems may create exclusion risks for:
Migrant workers
Elderly populations
Remote tribal communities
Workers facing Aadhaar authentication failures.
Agricultural and Labour Dimensions
60-Day Agricultural Pause
States may notify a combined 60-day no-work period during peak sowing and harvesting seasons to avoid labour shortages in agriculture while still ensuring workers receive the guaranteed 125 days annually.
Balancing Labour Markets
The provision reflects attempts to balance:
Rural employment guarantees
Agricultural labour availability
Farm productivity
Seasonal labour-market stability.
Rural Livelihood Implications
Reduced programme flexibility during agricultural off-seasons or rural distress periods may affect livelihood security among vulnerable households heavily dependent on public employment programmes.
Economic and Governance Implications
Shift from Rights-Based Welfare
Analysts argue the framework reflects a broader transition from a legally enforceable employment guarantee under MGNREGA toward a more administratively managed, fiscally controlled, and performance-oriented welfare architecture.
Fiscal Rationalisation
The Centre may seek to:
Cap expenditure liabilities
Improve efficiency
Enhance asset creation
Reduce fiscal unpredictability
associated with open-ended demand-driven employment guarantees.
Impact on Rural Safety Net
Concerns remain that limiting central liability through normative allocations could weaken rural social protection during:
Droughts
Economic slowdowns
Agrarian crises
Migration shocks.
Way Forward
Preserve Rights-Based Principles
Rural employment programmes should continue protecting legally enforceable employment guarantees while integrating efficiency and infrastructure objectives without undermining livelihood security for vulnerable populations.
Strengthen Participatory Governance
Worker unions, civil-society organisations, Gram Sabhas, and community institutions should be integrated meaningfully within monitoring, grievance-redressal, and implementation structures to strengthen accountability.
Ensure Fiscal Adequacy
Allocation frameworks must remain sufficiently flexible to respond rapidly during:
Rural distress
Natural disasters
Droughts
Economic slowdowns
without excessively burdening State finances.
Build Inclusive Digital Systems
Digital governance mechanisms should incorporate:
Offline alternatives
Grievance systems
Human oversight
Inclusion safeguards
to prevent exclusion of vulnerable rural workers from wage payments and employment access.
Prelims Pointers
VB-GRAMG increases guaranteed rural employment from 100 days to 125 days annually.
The new programme introduces a 60:40 Centre-State cost-sharing ratio for most States.
The allocation formula reportedly assigns 42.5% weight to GSDP distance.
Mahatma Gandhi National Rural Employment Guarantee Act was originally enacted in 2005.
The draft rules emphasise:
DBT
Aadhaar-based Payment Systems (APBS)
Geospatial planning
Digital monitoring systems.
Russia’s Hypersonic Oreshnik Missile System
Why in News?
Russia reportedly used the Oreshnik hypersonic intermediate-range ballistic missile (IRBM) during large-scale strikes against Ukraine, marking one of the latest deployments of advanced hypersonic missile systems in the ongoing Russia-Ukraine conflict.

Practice Question
“Hypersonic missile systems are transforming modern strategic deterrence and missile defence dynamics.” Examine in the context of Russia’s Oreshnik missile system and the global hypersonic arms race. (250 words)
Issue in Brief
Third Reported Operational Use
Reports indicate that Russia employed the Oreshnik missile during major coordinated missile and drone attacks on Ukrainian targets, reflecting increasing operational reliance on advanced precision long-range strike systems in contemporary warfare.
Advanced Hypersonic Capability
Oreshnik is reportedly a road-mobile hypersonic intermediate-range ballistic missile (IRBM) capable of carrying both conventional and nuclear warheads while travelling at extremely high speeds difficult for existing missile-defence systems to intercept effectively.
Strategic Significance
The missile demonstrates the growing strategic importance of:
Hypersonic technologies
Long-range precision strikes
MIRV capability
Rapid-response deterrence
in modern geopolitical and military competition.
What is Oreshnik?
Intermediate-Range Ballistic Missile
Oreshnik is classified as an Intermediate-Range Ballistic Missile (IRBM) with an estimated range reportedly between 3,000 and 5,500 kilometres, placing much of Europe and surrounding regions within operational strike range.
Hypersonic Weapon System
The missile reportedly travels at speeds between Mach 10 and Mach 11, equivalent to nearly 12,000–13,500 km/h, enabling extremely rapid target engagement and reducing enemy response time significantly.
Russian Meaning
The term “Oreshnik” reportedly means “hazel tree” or “hazelnut tree” in Russian and is believed to be associated technologically with the earlier Russian RS-26 Rubezh missile system.
Key Technical Features
Multiple Independently Targetable Reentry Vehicles (MIRVs)
Oreshnik reportedly possesses MIRV capability, enabling deployment of multiple independently targetable warheads capable of striking separate targets or expanding the area of destruction from a single missile launch.
Nuclear and Conventional Capability
The missile is reportedly dual-capable, meaning it can carry:
Conventional warheads
Nuclear warheads
thereby enhancing its role within both tactical warfare and strategic nuclear deterrence architectures.
Road-Mobile Launch Platform
Oreshnik reportedly uses a road-mobile launcher system, improving survivability through mobility, concealment, and rapid deployment while reducing vulnerability to pre-emptive enemy strikes.
Why Hypersonic Missiles Matter
Extremely High Speed
Hypersonic weapons travel at speeds exceeding Mach 5, dramatically reducing interception time and limiting the effectiveness of conventional missile-defence systems designed primarily against slower ballistic or cruise missiles.
Difficult to Intercept
Existing air-defence and anti-ballistic missile systems struggle to intercept hypersonic weapons because of:
Extreme velocity
Unpredictable trajectories
Manoeuvrability
Reduced detection-response windows.
Strategic Deterrence
Hypersonic systems strengthen strategic deterrence by enabling rapid precision strikes against:
Command centres
Air bases
Missile silos
Strategic infrastructure
before adversaries can effectively respond.
MIRV Capability and Strategic Implications ?
What is MIRV?
Multiple Independently Targetable Reentry Vehicles (MIRVs) allow a single missile to release multiple warheads capable of striking different targets independently during terminal descent phases.
Defence Saturation
MIRV systems complicate missile-defence interception because defending systems must intercept multiple warheads simultaneously, greatly increasing the probability of successful penetration through defensive shields.
Traditionally Associated with ICBMs
MIRV technology has historically been associated mainly with:
Intercontinental Ballistic Missiles (ICBMs)
Strategic nuclear deterrence systems
making its integration into hypersonic IRBMs particularly significant.
Strategic Role in Russia-Ukraine War
Precision Long-Range Strike
Oreshnik reportedly targets:
Military infrastructure
Command centres
Air bases
Deeply buried installations
enabling rapid high-intensity strikes deep inside enemy territory.
Psychological Warfare
Deployment of hypersonic systems also carries psychological and geopolitical significance by demonstrating technological superiority and creating uncertainty regarding interception capabilities among adversaries and allied defence systems.
Escalation Concerns
Use of nuclear-capable hypersonic systems increases concerns regarding:
Strategic escalation
Miscalculation risks
Arms-race dynamics
Nuclear threshold ambiguity
during ongoing geopolitical conflicts.
Global Hypersonic Arms Race
Major Powers Developing Hypersonic Weapons
Countries actively pursuing hypersonic weapon systems include:
Russia
China
United States
India
Changing Nature of Warfare
Hypersonic technologies are transforming strategic warfare by:
Compressing response time
Weakening traditional missile defence
Increasing first-strike capability
Enhancing precision deep-strike operations.
Strategic Stability Concerns
Analysts warn that widespread deployment of hypersonic systems may undermine existing strategic deterrence frameworks and increase instability because adversaries may perceive reduced warning time during crises.
India-Specific Relevance
India’s Hypersonic Programmes
India is also developing indigenous hypersonic technologies through programmes such as:
Hypersonic Technology Demonstrator Vehicle (HSTDV)
Advanced long-range missile systems
under the leadership of Defence Research and Development Organisation.
Regional Security Dynamics
Development of hypersonic systems by major powers affects India’s strategic calculations regarding:
Missile defence
Nuclear deterrence
Space security
Indo-Pacific military balance.
Need for Counter-Hypersonic Defence
India may increasingly require:
Advanced radar systems
Space-based surveillance
Directed-energy weapons
Integrated air-defence networks
to counter emerging hypersonic threats.
Governance & Arms-Control Concerns
Weak Existing Arms-Control Frameworks
Current international arms-control treaties inadequately regulate hypersonic weapons, creating growing concerns regarding strategic instability and absence of effective verification or transparency mechanisms.
Nuclear Ambiguity
Dual-capable hypersonic missiles carrying either conventional or nuclear warheads create ambiguity during conflict situations because adversaries may struggle to distinguish the nature of incoming strikes.
Reduced Decision Time
Hypersonic systems significantly compress military and political decision-making time during crises, increasing risks of accidental escalation or unintended retaliatory responses.
Challenges & Concerns
Missile Defence Limitations
Existing anti-ballistic missile systems remain relatively ineffective against highly manoeuvrable hypersonic weapons travelling at extremely high speeds and unpredictable flight trajectories.
Arms Race Escalation
Growing deployment of hypersonic weapons risks triggering a new strategic arms race among major powers competing for technological superiority and deterrence advantage.
High Development Costs
Hypersonic systems require:
Advanced propulsion technology
Heat-resistant materials
Precision guidance systems
Sophisticated testing infrastructure
making development technologically and financially demanding.
Strategic Instability
Faster strike capability and reduced warning times may weaken crisis stability by increasing incentives for pre-emptive action during geopolitical confrontations.
Way Forward
Strengthen Arms-Control Dialogue
Major powers should initiate international discussions regarding:
Hypersonic weapon regulation
Transparency mechanisms
Confidence-building measures
Strategic stability frameworks
to reduce escalation risks.
Invest in Counter-Hypersonic Systems
Countries must develop:
Advanced early-warning systems
Space-based tracking
AI-enabled interception technologies
Directed-energy defence systems
capable of responding to emerging hypersonic threats.
Enhance Strategic Communication
Clear doctrinal communication regarding deployment and use of dual-capable hypersonic systems is essential to reduce miscalculation risks during crises.
Accelerate Indigenous Research
India should continue strengthening indigenous aerospace and missile research ecosystems to maintain credible deterrence capability amid rapidly evolving strategic technologies.
Prelims Pointers
Oreshnik is a Russian hypersonic intermediate-range ballistic missile (IRBM).
Hypersonic weapons travel at speeds greater than Mach 5.
MIRV stands for Multiple Independently Targetable Reentry Vehicles.

Why is the Indian rupee falling?
Why in News?
The Indian rupee reportedly crossed nearly ₹96 per U.S. dollar in May 2026, compared to around ₹85 a year earlier, reflecting intensified external-sector pressures arising from rising crude oil prices, geopolitical tensions, higher U.S. interest rates, and sustained foreign capital outflows from emerging economies.

Practice Question
“A currency’s exchange rate reflects deeper structural realities of an economy’s external sector.” Examine the causes and consequences of rupee depreciation in the context of India’s balance-of-payments dynamics and global capital flows. (250 words)
Issue in Brief
Sharp Rupee Depreciation
The rupee-to-dollar exchange rate reportedly weakened sharply during 2025–26 because of rising oil import costs, persistent trade deficits, geopolitical uncertainty in West Asia, and large foreign capital outflows driven by global financial tightening and investor preference for safer dollar-denominated assets.
External-Sector Vulnerability
The depreciation highlights India’s continuing vulnerability arising from:
High crude oil import dependence
Persistent merchandise trade deficits
Dependence on volatile foreign portfolio investment
Exposure to global financial and geopolitical shocks affecting capital flows and energy markets.
RBI Intervention
Reserve Bank of India has intervened actively in currency markets by deploying foreign exchange reserves to smooth volatility, prevent speculative attacks, and stabilise investor confidence amid heightened uncertainty in global financial markets.
What is Exchange Rate?
Meaning
Exchange rate refers to the value or price of one currency relative to another currency. The rupee-dollar exchange rate specifically indicates how many Indian rupees are required to purchase one U.S. dollar in foreign exchange markets.
Demand-Supply Determination
Like commodity prices, exchange rates are determined through demand and supply conditions in global currency markets. Demand for rupees rises with exports and investment inflows, while imports and capital outflows increase demand for foreign currencies such as the U.S. dollar.
Economic Importance
Exchange-rate movements significantly affect:
Export competitiveness
Import costs
Inflation levels
External debt burden
Foreign investment flows
Overall macroeconomic and balance-of-payments stability.
Trade Deficit and Rupee Depreciation
Exports Increase Rupee Demand
When Indian firms export goods or services, foreign buyers pay in dollars or euros, which are converted into rupees for domestic payments such as wages and inputs, thereby increasing demand for the Indian currency.
Imports Weaken Rupee Demand
Imports require Indian companies to exchange rupees for foreign currencies, especially dollars. Large imports of crude oil, electronics, and gold therefore increase demand for dollars and place downward pressure on the rupee’s exchange rate.
Persistent Merchandise Trade Deficit
India consistently runs a merchandise trade deficit because imports, particularly crude oil, gold, machinery, and electronics, exceed exports. This persistent deficit increases external vulnerability and contributes to long-term depreciation pressure on the rupee.
Current Account Dynamics
Components of Current Account
India’s current account includes:
Merchandise trade
Services trade
Remittances
Investment-income flows
and reflects the country’s overall foreign exchange earnings and payment obligations with the rest of the world.
Role of Invisibles
India partly offsets its merchandise trade deficit through strong “invisibles” earnings generated from:
Software exports
Business services
Overseas remittances
especially from migrant workers in West Asia and advanced economies.
Current Account Deficit (CAD)
Despite strong services exports, India often records a Current Account Deficit (CAD) because total foreign exchange outflows on imports and payments exceed overall foreign exchange earnings from exports and remittances.
Capital Account and Rupee Stability
Importance of Capital Inflows
India finances its current account deficit through capital-account inflows such as:
Foreign Direct Investment (FDI)
Foreign Portfolio Investment (FPI)
External commercial borrowings
Banking capital flows
which support external-sector financing and forex reserve accumulation.
FDI vs FPI
FDI generally represents long-term productive investment in factories and businesses, whereas FPI mainly involves investment in financial assets such as stocks and bonds and therefore remains highly volatile and sentiment-driven.
Dependence on Volatile Flows
Heavy dependence on foreign portfolio flows exposes India to sudden exchange-rate instability because investors may rapidly withdraw capital during periods of global uncertainty, geopolitical tensions, or rising interest rates in advanced economies.
Foreign Portfolio Investment (FPI) and Rupee
Nature of FPI
Foreign Portfolio Investors move capital rapidly across countries seeking higher short-term financial returns. Such flows are highly sensitive to:
Global risk perception
Interest-rate differentials
Geopolitical instability
Currency expectations.
Impact of Capital Outflows
When FPIs sell Indian assets and convert rupees into dollars for repatriation, demand for dollars rises sharply while demand for rupees declines, leading to depreciation pressure on the Indian currency.
Recent FPI Outflows
The recent weakness in the rupee has reportedly been driven substantially by foreign investors retreating from emerging markets amid:
Higher U.S. bond yields
Global geopolitical tensions
Uncertainty regarding energy prices and global growth.
Historical Phases of Rupee Depreciation
2013 Taper Tantrum
During the 2013 “Taper Tantrum,” fears regarding U.S. Federal Reserve monetary tightening triggered large capital outflows from emerging economies, causing sharp depreciation of the rupee alongside widening current account deficits.
COVID-19 Shock
During the early phase of the COVID-19 pandemic in 2020, global investors shifted rapidly toward safer dollar assets, causing significant rupee depreciation amid heightened uncertainty and capital flight from emerging markets.
Recent Depreciation Episodes
Major depreciation phases also occurred during:
2018 global financial tightening
2022 energy-price shocks
2024–26 geopolitical tensions and sustained foreign capital outflows linked to global uncertainty and rising oil prices.
Economic Impact of Falling Rupee
Higher Import Costs
Rupee depreciation increases the domestic cost of imports. For instance, crude oil priced at $100 per barrel costs nearly ₹9,600 at ₹96/$, compared to about ₹8,500 at ₹85/$, thereby worsening India’s import bill significantly.
Imported Inflation
Higher import costs raise prices of:
Fuel
Fertilisers
Electronics
Industrial raw materials
contributing to inflationary pressures that affect households, industries, transportation costs, and overall economic stability.
Rising External Debt Burden
A weaker rupee increases repayment obligations on:
External commercial borrowings
Foreign-currency loans
Sovereign liabilities
thereby worsening financial stress for companies and institutions with significant dollar-denominated debt exposure.
Potential Benefits of Rupee Depreciation
Improved Export Competitiveness
A weaker rupee makes Indian exports cheaper in global markets, potentially improving competitiveness of sectors such as:
Textiles
Pharmaceuticals
Information Technology services
Engineering goods
Tourism-related services.
Services and Tourism Gains
Rupee depreciation can increase demand for Indian services and tourism because foreign consumers and travellers perceive Indian goods and services as relatively cheaper compared to competing international destinations.
Structural Constraints
However, depreciation alone cannot substantially boost exports without improvements in:
Manufacturing productivity
Logistics infrastructure
Supply-chain efficiency
Technological competitiveness
Global market access.
Role of RBI
Forex Market Intervention
Reserve Bank of India intervenes in foreign exchange markets by selling dollars from its reserves to increase demand for rupees and reduce excessive volatility during periods of sharp depreciation pressure.
India’s Forex Reserves
India’s foreign exchange reserves reportedly stood near USD 691 billion in March 2026, sufficient to cover approximately 10.8 months of imports, providing an important external-sector buffer against financial instability.
Preventing Speculative Attacks
RBI intervention helps prevent:
Panic depreciation
Currency speculation
Self-fulfilling capital-flight spirals
that could destabilise financial markets and weaken confidence in the Indian economy.
Oil Dependence and External Vulnerability
Heavy Crude Oil Dependence
India imports nearly 85% of its crude oil requirements, making the economy highly vulnerable to fluctuations in global oil prices, geopolitical instability in West Asia, and exchange-rate depreciation.
Double External Shock
Rising crude oil prices combined with rupee depreciation create a “double burden” because India must pay:
More dollars per barrel of oil
More rupees per dollar
worsening inflation and external deficits simultaneously.
West Asia Linkages
Geopolitical tensions in West Asia directly affect India’s:
Energy security
Current account deficit
Inflation levels
Shipping costs
Overall external-sector stability.
Challenges & Concerns
Volatile Capital Flows
Heavy dependence on short-term foreign portfolio investment exposes India to rapid financial instability because global investors can quickly withdraw funds during periods of uncertainty, thereby intensifying exchange-rate volatility and external-sector stress.
Inflationary Pressures
Persistent rupee depreciation can worsen:
Fuel inflation
Food inflation
Transportation costs
Industrial input prices
thereby affecting household welfare, industrial profitability, and macroeconomic stability.
External Debt Risks
Companies with substantial foreign-currency borrowings face higher repayment burdens when the rupee weakens, increasing financial vulnerability and potentially affecting banking-sector stability through rising debt-servicing pressures.
Weak Export Capacity
India’s manufacturing and export sectors continue facing structural constraints such as infrastructure gaps, logistics inefficiencies, and limited technological competitiveness, reducing the potential gains from rupee depreciation.
Way Forward
Reduce Oil Import Dependence
India should accelerate:
Renewable energy deployment
Electric mobility
Ethanol blending
Domestic energy diversification
to reduce vulnerability arising from imported crude oil dependence and external energy-price shocks.
Strengthen Export Competitiveness
Improving:
Manufacturing productivity
Logistics infrastructure
Ease of doing business
Global value-chain integration
is essential for converting exchange-rate depreciation into sustained export growth and external-sector resilience.
Manage Volatile Capital Flows
Policymakers may require stronger macroprudential safeguards and regulatory measures to reduce vulnerability arising from destabilising speculative capital flows while continuing to attract stable long-term investments.
Maintain Adequate Forex Reserves
Sustaining strong foreign exchange reserves remains critical for defending the rupee during periods of external stress and ensuring confidence in India’s macroeconomic and financial stability.
Prelims Pointers
Exchange rate refers to the value of one currency relative to another currency in foreign exchange markets.
A Current Account Deficit (CAD) occurs when a country’s import payments and external outflows exceed export earnings and inward transfers.
Foreign Portfolio Investment (FPI) mainly involves investment in stocks and bonds and is generally more volatile than Foreign Direct Investment (FDI).
Reserve Bank of India intervenes in forex markets using foreign exchange reserves to stabilise excessive currency volatility.
India imports nearly 85% of its crude oil requirements, making the economy highly vulnerable to external energy-price shocks.
Rice feeds billions of people — but its role in fuelling climate change is growing
Why in News?
A recent global study warned that greenhouse gas emissions from rice paddies have nearly doubled since the 1960s, reaching approximately 1.1 billion tonnes CO₂-equivalent annually during the 2010s, roughly comparable to emissions generated by 239 million cars every year globally.

Issue in Brief
Rice as Global Staple Food
Rice remains the primary food source for more than half of the global population, particularly across South Asia, Southeast Asia, and East Asia, making rice cultivation critically important for food security, nutrition, rural employment, and agricultural livelihoods.
Massive Emission Source
Scientists estimate that rice paddies emitted nearly 1.1 billion tonnes CO₂-equivalent annually during the 2010s, making rice cultivation one of the largest agricultural greenhouse-gas sources globally outside livestock-related emissions.
Emissions Nearly Doubled
The study found that greenhouse gas emissions from rice cultivation have nearly doubled globally since the 1960s because of expanding cultivation areas, intensive farming practices, higher fertiliser usage, and climate-induced increases in microbial activity.
Why Rice Paddies Emit Greenhouse Gases
Flooded Soil Conditions
Rice cultivation usually occurs under flooded conditions where oxygen-deficient soils create an ideal environment for anaerobic microbes that generate large quantities of climate-warming gases, particularly methane and nitrous oxide.
Methane Emissions
Waterlogged rice fields promote anaerobic decomposition of organic matter, releasing methane (CH₄), a greenhouse gas possessing significantly greater short-term warming potential than carbon dioxide.
Nitrous Oxide Emissions
Intensive application of nitrogen-based fertilisers increases emissions of nitrous oxide (N₂O), especially when fields alternate between wet and dry conditions during irrigation cycles.
Key Drivers of Rising Emissions
Expansion of Rice Cultivation
More than half of the increase in rice-related greenhouse gas emissions reportedly resulted from expansion of rice-growing areas, especially in Africa and Asia where rising population and food demand increased rice cultivation significantly.
Intensification of Farming
Farmers increasingly adopted:
High-yielding varieties
Dense planting
Fertiliser-intensive cultivation
Organic soil amendments
improving productivity but simultaneously increasing greenhouse gas emissions from agricultural soils.
Straw & Residue Management
Leaving rice straw and stalks in flooded fields after harvest reportedly contributed around 18% of the increase in overall rice emissions since the 1960s because decomposing organic matter increases methane generation.
Rising Global Temperatures
Climate change itself accelerates microbial activity in flooded soils, thereby increasing methane production and creating a dangerous positive feedback loop between agricultural emissions and global warming.
Fertiliser & Irrigation Dimensions
Rising Fertiliser Use
Global synthetic nitrogen fertiliser use reportedly increased by approximately 76% after 2000, significantly increasing nitrous oxide emissions from rice cultivation systems across major rice-producing economies.
Continuous Flooding Problem
Traditionally, rice paddies remained continuously flooded throughout the growing season, creating persistent anaerobic conditions that favour constant methane generation by soil microbes.
Intermittent Flooding Practices
Increasing adoption of intermittent flooding or periodic drainage has reduced methane emissions in several regions, although slight increases in nitrous oxide emissions may occur because of changing soil oxygen conditions.
Scientific Methodology of the Study
Ecosystem Modelling
Researchers used advanced ecosystem computer models to simulate:
Crop growth
Water conditions
Soil chemistry
Greenhouse gas emissions
across global rice production systems.
Artificial Intelligence Integration
Artificial intelligence and machine-learning techniques improved estimation accuracy in regions lacking sufficient observational data, enabling more comprehensive assessment of global rice-related greenhouse gas emissions.
Meta-Analysis Approach
Scientists analysed evidence from more than 1,200 field experiment sites worldwide to understand how irrigation methods, fertiliser usage, and residue-management practices influence greenhouse gas emissions from rice cultivation.
Climate-Smart Mitigation Strategies
Improved Water Management
Periodic draining of rice fields can significantly reduce methane generation by interrupting anaerobic microbial activity responsible for methane production under continuously flooded conditions.
Optimised Fertiliser Application
Reducing excessive nitrogen fertiliser use lowers:
Nitrous oxide emissions
Water pollution
Farmer input costs
without substantially affecting crop productivity in many regions.
Biochar Application
Converting crop residues into biochar before incorporation into soils can improve soil fertility, stabilise soil carbon, and reduce methane emissions compared to direct straw decomposition in flooded fields.
Reduced Tillage
Reduced tillage may improve soil-carbon retention in cooler climates, though its effectiveness varies considerably depending upon local climatic conditions and irrigation practices.
Limits of Current Mitigation
Modest Emission Reduction Potential
Researchers estimated that currently available climate-smart practices could reduce global rice-related greenhouse gas emissions by only around 10% by mid-century, indicating the need for more advanced mitigation technologies.
Regional Variability
No single mitigation strategy works effectively everywhere because:
Climate conditions
Soil properties
Irrigation systems
Farming methods
differ substantially across rice-growing regions globally.
Food Security Constraints
Significant emission reductions cannot compromise rice productivity because billions of people remain dependent on rice as a staple food source for nutritional and livelihood security.
India-Specific Relevance
India as Major Rice Producer
India remains one of the world’s largest rice producers and exporters, making rice cultivation crucial for:
Food security
Rural employment
Agricultural exports
Livelihood generation
Methane Emission Concerns
Paddy cultivation contributes substantially to India’s agricultural methane emissions, particularly in:
Punjab
Haryana
Eastern India
Coastal rice-growing regions
Groundwater Stress
Continuous flooding practices in northwestern India have intensified:
Groundwater depletion
Electricity consumption
Soil degradation
Environmental stress
alongside rising greenhouse gas emissions.
Governance & Policy Dimensions
Climate-Smart Agriculture
India increasingly promotes:
Climate-smart agriculture
Precision farming
Water-efficient irrigation
Sustainable nutrient management
under broader agricultural sustainability and climate-adaptation frameworks.

Agricultural emission reduction forms an important component of global climate objectives under frameworks such as the Paris Agreement and UN climate negotiations.
Balancing Food & Climate Goals
Policymakers face the difficult challenge of balancing:
Food security
Farmer incomes
Export competitiveness
Climate mitigation
within rice-dependent developing economies.
Challenges & Concerns
Food Security vs Emission Reduction
Rice cultivation remains essential for feeding billions of people, making aggressive emission-reduction strategies politically and economically difficult without ensuring stable agricultural productivity.
Farmer Adoption Barriers
Adoption of climate-smart technologies often remains constrained because of:
High costs
Weak extension services
Limited awareness
Inadequate irrigation infrastructure
Regional Disparities
Effectiveness of mitigation strategies varies significantly depending upon:
Temperature
Soil quality
Water availability
Farming systems
making universal solutions difficult.
Climate Feedback Risks
Rising global temperatures may further increase methane generation in flooded soils, worsening agricultural greenhouse gas emissions and intensifying long-term climate risks.
Way Forward
Promote Climate-Smart Rice Cultivation
Governments should expand support for:
Alternate Wetting and Drying (AWD)
Precision nutrient management
Sustainable irrigation systems
Low-emission rice cultivation technologies
Strengthen Agricultural Research
Greater investment is needed in:
Methane-resistant rice systems
Biochar technologies
Climate-resilient agriculture
Soil-carbon management
to improve sustainability outcomes.
Improve Farmer Awareness
Agricultural extension systems should actively promote:
Scientific fertiliser usage
Water-saving techniques
Residue management
Low-emission farming practices
especially among small and marginal farmers.
Integrate Climate & Food Policies
Agricultural policies must simultaneously prioritise:
Food security
Climate mitigation
Farmer livelihoods
Water conservation
through integrated long-term planning approaches.
Prelims Pointers
Flooded rice paddies emit significant quantities of:
Methane (CH₄)
Nitrous oxide (N₂O)
Methane possesses much higher short-term warming potential than carbon dioxide.
Alternate Wetting and Drying (AWD) irrigation can reduce methane emissions from rice cultivation systems.
Biochar is produced through low-oxygen burning of biomass and can improve soil-carbon stability.
Rice cultivation is among the largest agricultural greenhouse-gas sources outside livestock production globally.

Issue in Brief
New Mathematical Framework
The study proposes a nonlinear mathematical model capable of explaining nearly 12,000 years of human population growth by integrating different historical population-growth regimes into a single analytical and feedback-based framework.
Hypothetical Worst-Case Scenario
Under a deliberately conservative assumption where Earth’s sustainable carrying capacity abruptly declines to nearly 2 billion people, the model projects a rapid global population decline with possible halving by approximately 2064.
Clarification by Researchers
The researchers clearly emphasised that the study is not a prediction or forecast, but rather an illustrative mathematical scenario intended to demonstrate the sensitivity of human population systems to sudden environmental or societal disruptions.
About the Mathematical Model
Nonlinear Dynamical Equation
The model uses a nonlinear differential equation incorporating feedback relationships between population growth, resource availability, and ecological carrying capacity, thereby capturing both expansionary and stabilising phases of demographic evolution.
Unified Population Theory
The framework combines major demographic theories including:
Malthusian exponential growth
Logistic growth
Hyperbolic population growth
within a single compact mathematical structure explaining long-term demographic behaviour.
Origin in Physics
Interestingly, the equation was originally developed in the context of the physics of disordered systems, before being adapted to analyse global population dynamics and long-term sustainability scenarios.
Concept of Carrying Capacity
Carrying capacity refers to the maximum population size that Earth’s ecological systems can sustainably support without causing irreversible environmental degradation, biodiversity collapse, or exhaustion of critical natural resources.
Key Determinants
Carrying capacity depends upon multiple interconnected factors including:
Food production
Freshwater availability
Climate stability
Energy systems
Technological efficiency
Ecosystem resilience
Environmental Constraints
Climate change, soil degradation, biodiversity loss, freshwater scarcity, pollution, and ecosystem collapse could significantly reduce Earth’s long-term carrying capacity if environmental pressures continue intensifying globally.
Classical Population Theories
Malthusian Theory
Thomas Robert Malthus argued that population tends to grow geometrically while food production increases arithmetically, potentially resulting in famine, disease, and population corrections through natural checks.
Logistic Growth Theory
Logistic growth theory proposes that population growth initially accelerates rapidly but eventually slows and stabilises near environmental carrying capacity because of resource constraints and ecological limitations.
Demographic Transition Theory
Modern demographic transition theory explains how societies transition from:
High birth and death rates
To low birth and death rates
during industrialisation, urbanisation, and socio-economic development.
Global Population Trends
Current Global Population
According to the United Nations, global population crossed approximately 8 billion in 2022, though overall growth rates are gradually slowing because of declining fertility in many regions.
Declining Fertility Rates
Several developed and emerging economies are witnessing:
Population ageing
Shrinking workforce
Declining fertility rates
especially across Europe, East Asia, and parts of Latin America.
Regional Population Growth
Future population growth is expected to remain concentrated largely in:
Sub-Saharan Africa
South Asia
due to relatively higher fertility rates and younger demographic structures.
