GS Paper 2:
India–Oman CEPA
Source: ET
Subject: International Relations
Context: India and Oman signed a Comprehensive Economic Partnership Agreement (CEPA) marking India’s second major trade pact in West Asia after the UAE.
About India–Oman CEPA:
What it is?
- A Comprehensive Economic Partnership Agreement (CEPA) aimed at deepening trade, services, investment and mobility between India and Oman.
- It is Oman’s first bilateral trade agreement since the US FTA (2006).
Key features of India–Oman CEPA:
- Zero-duty market access: Oman has eliminated customs duties on 98.08% of its tariff lines, covering 99.38% of India’s exports, making Indian goods significantly more price-competitive.
- Boost to labour-intensive sectors: Sectors like textiles, leather, gems & jewellery, engineering goods, pharmaceuticals and automobiles gain from full tariff elimination, supporting jobs, MSMEs and export-led growth.
- Wide services liberalisation: Oman has opened 127 services sub-sectors, including IT, professional services, R&D, education and healthcare, creating high-value opportunities for Indian service providers.
- Enhanced mobility for professionals (Mode 4): The quota for intra-corporate transferees rises from 20% to 50%, while contractual service suppliers can stay up to two years, extendable further, improving workforce mobility.
- 100% FDI in services: Indian companies are allowed full foreign ownership in major services sectors in Oman, enabling long-term commercial presence and regional expansion.
- AYUSH and traditional medicine access: For the first time globally, a country has committed to traditional medicine across all modes, opening the Gulf market for India’s AYUSH and wellness sectors.
- Faster pharmaceutical approvals: Acceptance of approvals by USFDA, EMA and UKMHRA reduces regulatory delays and costs, speeding up Indian pharma exports to Oman.
Oman deal and India’s West Asia trade strategy:
- Market diversification beyond the West: The Oman CEPA helps India reduce overdependence on the US and EU, where exports face higher tariffs and carbon-linked barriers like CBAM.
E.g. EU’s carbon tax has raised compliance costs for Indian steel and cement exporters, making West Asia a safer alternative market.
- Oman as a gateway economy: Oman’s location near the Strait of Hormuz allows Indian goods to access West Asia, East Africa and trans-shipment hubs efficiently.
E.g. Ports like Duqm and Sohar can serve as re-export bases for Indian engineering and consumer goods.
- Strategic foothold within GCC: With FTAs with UAE (2022) and Oman (2025), India gains leverage despite stalled India–GCC negotiations.
E.g. Two bilateral pacts help India avoid tariff disadvantages in Gulf markets dominated by EU and East Asian exporters.
- Services-led trade expansion: The deal strengthens India’s core strength in IT, healthcare, education and professional services, sectors less affected by tariff barriers.
E.g. Oman’s services imports are USD 12.5 billion, while India’s share is only 5.3%, indicating untapped potential.
- Energy-security complementarity: India secures stable access to crude oil, LNG, fertilisers and petrochemical inputs, vital for domestic energy and agriculture.
E.g. Oman remains a reliable LNG supplier amid global energy volatility after the Ukraine conflict.
Challenges associated with the Oman CEPA:
- Limited market size: Oman’s domestic market is small, which may restrict large-scale export growth beyond niche and re-export segments.
E.g. Oman’s annual imports are around USD 40 billion, far smaller than UAE or Saudi Arabia.
- Competitiveness and quality gaps: Indian exporters must upgrade quality, packaging and branding to sustain long-term market presence.
E.g. Gulf consumers increasingly prefer premium and certified products.
- Implementation and NTB risks: Actual gains depend on smooth implementation of services mobility and non-tariff barrier
E.g. Delays in professional visa processing can dilute Mode 4 benefits.
- Regional geopolitical volatility: West Asia remains exposed to conflicts, energy shocks and shipping disruptions.
E.g. Red Sea tensions have recently raised freight and insurance costs.
- Fragmentation of GCC trade policy: Multiple bilateral FTAs may complicate the path to a comprehensive India–GCC trade agreement.
E.g. Different rules of origin can increase compliance burden for exporters.
Way ahead:
- Develop Oman as a re-export hub: Position Oman as a logistics and redistribution centre for Indian goods entering Africa and the Middle East.
E.g. Leveraging Duqm port under India–Oman industrial cooperation.
- Move up the value chain: Shift focus from raw exports to value-added manufacturing and brand-led exports.
E.g. Engineering goods and finished jewellery instead of raw materials.
- Deepen services and skills integration: Fast-track mutual recognition agreements and professional mobility frameworks.
E.g. Easier entry for Indian doctors, architects and IT professionals.
- Align with domestic growth schemes: Integrate CEPA benefits with PLI schemes, MSME clusters and skilling initiatives.
E.g. PLI-supported auto and electronics exports to Gulf markets.
- Use bilateral success to revive GCC talks: Leverage Oman and UAE pacts to rebuild momentum for an India–GCC FTA.
E.g. Demonstrating mutual gains to other GCC members.
Conclusion:
The India–Oman CEPA strengthens India’s West Asia trade pivot at a time of rising protectionism in the West. By combining tariff-free goods access, deep services commitments and professional mobility, the deal enhances India’s export resilience. If effectively implemented, it can transform Oman into a strategic economic bridge linking India to the wider Gulf and Africa.

Nuclear Energy and the SHANTI Bill: Promise, Peril and Policy Choices
Source: PRS
Subject: Nuclear Energy
Context: Parliament has passed the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Bill, 2025, marking a major overhaul of India’s nuclear governance framework.
About Nuclear Energy and the SHANTI Bill: Promise, Peril and Policy Choices
What is the SHANTI Bill?
- The SHANTI Bill, 2025 replaces the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010.
- It provides a new legal framework to expand nuclear power, permit private participation, and restructure liability and regulation in the nuclear sector.
Key features of the Bill:
- Opening nuclear sector to non-government entities: The Bill allows licences for building, owning and operating nuclear plants to private companies, joint ventures and other permitted persons, under government licensing and regulatory oversight.
- Tiered liability framework: It introduces graded operator liability caps ranging from ₹100 crore to ₹3,000 crore based on reactor capacity, with excess liability borne by the central government.
- Removal of supplier liability for defects: The operator’s right of recourse against suppliers for defective equipment or materials is removed, retaining recourse only for contractual or deliberate acts.
- Statutory status to AERB: The Atomic Energy Regulatory Board (AERB) is granted statutory recognition, tasked with ensuring nuclear and radiation safety.
- Expanded territorial coverage of claims: Compensation claims may now extend to nuclear damage in foreign territories, subject to specified conditions.
- New appellate mechanism: The Bill establishes an Atomic Energy Redressal Advisory Council, with further appeals lying before the Appellate Tribunal for Electricity.
Need for the SHANTI Bill:
- Rising energy demand and decarbonisation goals: India’s growing economy and digitalisation require massive energy expansion, while net-zero commitments demand low-carbon baseload sources like nuclear.
- Limitations of renewables alone: Solar and wind are intermittent, land-intensive and storage-dependent; nuclear provides reliable baseload power for a decarbonised grid.
- Public sector capacity constraints: NPCIL and DAE face financial and execution limits in scaling up nuclear capacity to 100 GW without private capital and expertise.
- Global best practices and investment flows: Opening the sector aligns India with global nuclear markets and enables access to technology, finance and supply chains.
Issues associated with the SHANTI Bill:
- Dilution of liability and public safety concerns: Low liability caps and removal of supplier liability risk socialising catastrophic costs, contrary to the polluter pays principle.
- Lessons from Bhopal and Fukushima ignored: Past industrial disasters underline the need for strong accountability, which critics argue the Bill weakens.
- Regulatory independence questioned: Despite statutory status, AERB remains executive-controlled, raising concerns of regulatory capture.
- Radioactive waste and decommissioning gaps: The Bill lacks a clear funding and responsibility framework for long-term waste management and decommissioning.
- Labour and environmental justice risks: Private participation may increase reliance on contract labour, heightening occupational and environmental risks.
- Energy sovereignty concerns: Higher foreign participation could deepen technology dependence, weakening India’s indigenous nuclear trajectory.
Way ahead:
- Strengthen liability and accountability mechanisms: Revisit liability caps, restore meaningful supplier accountability, and introduce explicit criminal negligence provisions.
- Ensure truly independent regulation: Reform appointment processes and empower AERB with autonomy, transparency and parliamentary oversight.
- Create a nuclear waste and decommissioning fund: Mandate fully funded, ring-fenced mechanisms to manage intergenerational radioactive waste burdens.
- Balance nuclear expansion with renewables: Adopt a diversified energy strategy, prioritising grid modernisation, storage and energy efficiency alongside nuclear.
- Enhance public consultation and trust: Institutionalise community participation, environmental safeguards and transparency in nuclear siting and operations.
Conclusion:
The SHANTI Bill, 2025 represents a transformative shift in India’s nuclear energy governance, driven by decarbonisation and development goals. While it can unlock investment and accelerate capacity expansion, weakened liability, regulatory risks and safety concerns remain significant. A balanced approach—combining nuclear growth with strong accountability, public trust and renewable integration—is essential for sustainable energy security.

El Niño
Source: DTE
Subject: Geography
Context: Climate models and ocean observations show early signals of a possible El Niño return in 2026, as warming in the equatorial Pacific weakens La Niña conditions.
About El Niño:
- What it is?
-
- El Niño is the warm phase of the El Niño–Southern Oscillation (ENSO), marked by abnormal warming of surface waters in the eastern and central equatorial Pacific Ocean.
- It occurs irregularly every 2–7 years and tends to raise global average temperatures.
- How it forms?
-
- Trade winds weaken along the equator, allowing warm surface waters to shift eastward from the western Pacific toward South America.
- The thermocline deepens in the eastern Pacific, suppressing upwelling of cold, nutrient-rich water.
- This alters atmospheric circulation, linking oceanic warming with pressure changes known as the Southern Oscillation.
- Indicators:
-
- Sea Surface Temperature (SST) anomalies in the Niño regions.
- Subsurface ocean heat build-up (warm water pools at 100–250 m depth).
- Oceanic Niño Index (ONI): SST anomalies of ≥ +0.5°C (or +0.9°F) for at least five consecutive three-month periods.
- Weakening or reversal of Walker Circulation and trade winds.
- Factors affecting El Niño:
-
- Strength and persistence of trade winds.
- Subsurface heat content of the Pacific Ocean.
- Interaction between ocean temperatures and atmospheric pressure systems.
- Natural climate variability and long-term global warming, which can amplify impacts.
- Implications:
-
- Global warming boost, often making El Niño years among the hottest on record.
- India: Increased risk of weaker monsoons and droughts.
- South America: Heavy rainfall, floods and coastal erosion.
- Australia & Southeast Asia: Droughts, heatwaves and wildfires.
