The IEA mandates its full member countries to hold oil stocks equivalent to at least 90 days of their net oil imports. As an 'Association country' and not a full member, India is not legally bound by this 90-day mandate. However, India actively participates in IEA discussions and recognizes the importance of strategic reserves. While India aims to increase its reserve capacity, its current strategic reserves (5.33 MMT) provide for a much shorter duration of its crude oil requirement, which is a key area of focus for expansion.

When a global supply shock occurs, international crude oil prices surge due to reduced availability. By releasing oil from strategic stockpiles, governments effectively increase the supply of crude oil into the domestic market. This increased supply helps to offset the global shortage, preventing or mitigating sharp increases in the price of crude oil for domestic refineries. Consequently, this stabilizes the cost of refined products like petrol and diesel, protecting consumers and industries from extreme price volatility and inflation.

• •Global supply shock reduces availability, causing international price surges.
• •Releasing stockpiles increases domestic crude oil supply.
• •Offsets global shortage, stabilizing crude prices for domestic refineries.
• •Prevents sharp increases in petrol/diesel prices, protecting consumers and industries.

Arguments for expansion include enhanced energy security against supply disruptions (like the 2026 Strait of Hormuz closure), greater leverage during international energy crises, and better insulation from global price volatility, which directly impacts inflation and economic stability. However, arguments against significant expansion involve the substantial upfront capital cost for building new caverns, the ongoing maintenance expenses, and the opportunity cost of tying up large amounts of capital in stored oil, which could otherwise be invested. Critics also point to the environmental risks associated with large-scale storage and the potential for oil to become a stranded asset in a future green energy transition.

• •For Expansion: Enhanced energy security, greater geopolitical leverage, better insulation from price volatility, macroeconomic stability.
• •Against Expansion: High capital and maintenance costs, opportunity cost of capital, environmental risks, potential for stranded assets in energy transition.

The Strait of Hormuz is a critical maritime chokepoint through which nearly 50% of India's oil imports traditionally pass. Its vulnerability to geopolitical conflicts, as highlighted by the 2026 West Asia conflict and Iran's actions, poses a significant threat to India's energy security. To mitigate this, India has actively diversified its crude oil import sources, now importing from about 40 countries. Crucially, recent developments in 2026 showed that 70% of India's crude imports now come from routes outside the Strait of Hormuz, a substantial increase from 55%, demonstrating a deliberate and successful strategy to reduce reliance on this single chokepoint.

While crude oil stockpiles are crucial, India employs several complementary strategies. Diversification of import sources is paramount, as evidenced by importing from 40 countries and reducing reliance on the Strait of Hormuz. Secondly, India is aggressively pushing for a transition to renewable energy sources (solar, wind) to reduce overall fossil fuel dependence. Thirdly, enhancing domestic oil and gas exploration and production is a continuous effort. Lastly, measures like increasing domestic LPG production by 25% and prioritizing natural gas allocation (as seen with the Essential Commodities Act in 2026) aim to manage demand and supply of other critical energy sources during disruptions, thereby easing pressure on crude oil.

• •Diversification of crude oil import sources.
• •Accelerated transition to renewable energy.
• •Enhancing domestic oil and gas exploration and production.
• •Demand-side management and ensuring supply of other energy sources (e.g., LPG, natural gas).

The decision to release oil from India's SPR is a high-level government decision, typically taken by the Ministry of Petroleum and Natural Gas, often in consultation with the Prime Minister's Office and other relevant ministries. Key factors considered include the severity and projected duration of the global supply disruption, the potential impact on domestic fuel prices and inflation, the current level of commercial stockpiles, and the broader geopolitical implications. Consultation with international bodies like the International Energy Agency (IEA) is also common, especially during a severe global supply crisis, to ensure a coordinated international response and maximize impact.

The primary criticism is that India's current SPR capacity of approximately 5.33 million metric tonnes (MMT) provides for a relatively limited number of days of crude oil requirement, especially considering India's high import dependence. This capacity falls short of the IEA's 90-day mandate for full members. The government's long-term vision involves expanding this capacity significantly. Phase II of the SPR programme aims to add 6.5 MMT of new storage at Chandikhol (Odisha) and Padur (Karnataka), which would substantially increase the buffer against supply shocks and move India closer to a more robust energy security posture.

• •Current capacity (5.33 MMT) provides limited days of import cover.
• •Falls short of IEA's 90-day mandate.

ISPRL (Indian Strategic Petroleum Reserves Limited) is the special purpose vehicle responsible for the construction, maintenance, and management of India's Strategic Petroleum Reserves. It is a wholly owned subsidiary of the Oil Industry Development Board (OIDB). The OIDB, in turn, functions under the administrative control of the Ministry of Petroleum and Natural Gas. This structure ensures that while ISPRL handles the operational aspects of SPR, it remains accountable to the broader policy framework and oversight provided by the OIDB and the Ministry.

While not a direct part of the physical stockpiles, increased purchases of discounted Russian oil by Indian refiners during the 2026 West Asia conflict served as a complementary strategy to enhance energy security. By diversifying procurement sources and taking advantage of market opportunities, India effectively reduced its immediate reliance on traditional, potentially disrupted supply routes and expensive international markets. This proactive approach ensures a continuous flow of crude oil, reduces the strain on existing stockpiles, and provides a cost-effective way to maintain supply stability, thereby indirectly bolstering the nation's energy resilience alongside its physical reserves.

• •Diversifies procurement sources beyond traditional routes.
• •Reduces immediate reliance on potentially disrupted and expensive markets.
• •Ensures continuous crude oil flow, easing pressure on existing stockpiles.
• •Cost-effective way to maintain supply stability.

Several long-term structural changes could impact India's SPR strategy. The global energy transition towards renewables might reduce overall crude oil demand in the long run, potentially making large stockpiles less critical or even leading to stranded assets. However, during the transition phase, oil market volatility could increase, making strategic reserves even more important as a buffer. The emergence of new oil and gas producers or shifts in geopolitical alliances could also alter supply routes and chokepoint vulnerabilities. Furthermore, advancements in energy storage technologies (e.g., battery storage, hydrogen) could offer alternative forms of energy security, potentially diversifying the 'stockpile' concept beyond just crude oil. India will need to continuously re-evaluate the optimal size and composition of its energy reserves in this evolving landscape.

• •Energy Transition: Reduced long-term crude demand vs. increased short-term volatility.
• •New Producers/Geopolitics: Shifts in supply routes and chokepoint relevance.
• •Technological Advancements: Alternative energy storage technologies (e.g., hydrogen, batteries) as future 'reserves'.
