India's Push for Energy Security: Building Strategic Oil Reserves

The urgent need for India to strengthen its energy security has intensified due to ongoing global tensions and unreliable supply chains. While recent domestic measures like fuel tax cuts and ethanol blending offer temporary help for consumers, the nation's long-term strategy heavily depends on the strong expansion of its Strategic Petroleum Reserves (SPRs). This initiative is a costly shift aimed at meeting global energy security standards, particularly the International Energy Agency's (IEA) recommendation of 90 days' net import cover. India's current combined strategic and commercial stocks provide about 74 days of cover, falling short, with specific reserves contributing only around 9.5 days. Global volatility, worsened by events like disruptions in shipping lanes, highlights the strategic importance of these reserves, even as financial and operational challenges grow.

High Costs of Building Strategic Oil Reserves

India's SPR program, managed by Indian Strategic Petroleum Reserves Limited (ISPRL), involves significant investment and long timelines for expansion. Phase I, completed by 2019, established 5.33 million metric tons (MMT) of capacity across three underground caverns. Phase II, approved in 2021, aims to add another 6.5 MMT, targeting completion by 2028-2029. Building these special facilities, especially underground rock caverns, is inherently slow and expensive. Furthermore, India's mix of imported oil, which includes heavier crudes from regions like the Middle East and Russia, requires special infrastructure adjustments that add to the cost and complexity. The government's strategy to involve private players through public-private partnerships (PPPs), using models like 'design, build, finance, operate, and transfer' (DBFOT), is an important factor, but getting significant private investment remains a challenge.

How India's Reserves Compare Globally

India's SPR capacity, while growing, is smaller than those of major players. China has the world's largest strategic oil reserves. The United States holds the second-largest SPR with a capacity of 714 million barrels, alongside large commercial reserves. Japan, which has few domestic resources, maintains significant reserves. In contrast, India's strategic reserves stood at 21.4 million barrels (approximately 3.37 MMT) as of March 2025, using about 64% of its SPR capacity. While the IEA requires members to hold 90 days of net import cover, India's combined reserves are around 74 days, with specific reserves providing only about 9.5 days. Other Asian nations like South Korea also maintain substantial reserves. This shows the scale of investment and commitment needed for India to meet global standards.

Challenges and Financial Strain in SPR Expansion

Despite the strategic necessity, India's SPR expansion faces major challenges that could affect its effectiveness on time. The slow pace of project completion, made worse by issues like land acquisition and environmental approvals, could delay vital capacity increases for energy security. Getting private investors involved in SPR development has been difficult, as early profit models have struggled to attract participation. A single private contract with Megha Engineering & Infrastructures Ltd. (MEIL) for a build-to-operate facility shows that private sector involvement is still in its early stages. Most Indian oil companies are state-owned (PSUs), meaning much of the cost for maintaining reserves could fall on the government or the PSUs, potentially straining their finances.

The strategy's reliance on storing diverse crude types also presents logistical and financial challenges. While lighter crudes like US WTI help diversify supply, they require major changes to India's refinery infrastructure, which is mostly built for heavier, sour crudes from the Middle East and Russia. Importing heavier crudes from Brazil and Venezuela could be cheaper for immediate use and help offset costs for lighter SPR crudes. Long-term storage and handling costs for these heavier oils are also factors. The need to diversify away from vital shipping lanes like the Strait of Hormuz, where about 52% of India's crude imports pass, adds complexity, potentially requiring longer and costlier shipping routes. The coordinated release of 400 million barrels by IEA members in March 2026, the largest ever, shows the scale of global disruption but also highlights that these strategic buffers are limited and costly to replenish.

Future Plans and Financial Realities

India's SPR program is on track for expansion, with Phase II aiming to reach 11.83 MMT, potentially covering 86 days of supply. Plans also include overseas storage, with talks underway with Oman, a strategy allowed by IEA agreements. Achieving these ambitious plans depends on navigating complex financial matters, effectively attracting private investors, and adjusting refinery setups. Global energy markets are shaped by geopolitical volatility and the energy transition. India's ability to maintain energy security depends on sustaining these costly SPR efforts while also building a more diverse and resilient energy system. The focus is shifting from affordability to resilience, a trend likely to drive domestic capital spending across the energy supply chain.
