How many barrels of oil are in India's SPRs?

India's Strategic Petroleum Reserves hold roughly 39 million barrels of crude oil across three underground caverns, enough to cover about 9 to 10 days of national consumption. That number sits at the heart of how the country thinks about energy security, and it matters whenever you read about the crude oil and energy market in news headlines.

The exact figure has shifted over the years as new caverns are commissioned and old ones top up. Here is the full picture, the math behind it, and why this stockpile is much smaller than you might expect.

What India's strategic reserves currently hold

The Indian Strategic Petroleum Reserves Limited, a subsidiary of the Oil Industry Development Board, runs the programme. As of the latest official data, the three operational underground reserves are:

• Visakhapatnam, Andhra Pradesh — capacity of 1.33 million tonnes (about 9.8 million barrels)
• Mangaluru, Karnataka — capacity of 1.5 million tonnes (about 11 million barrels)
• Padur, Karnataka — capacity of 2.5 million tonnes (about 18.3 million barrels)

Total Phase I capacity comes to roughly 5.33 million tonnes, which translates to about 39 million barrels. The fill level varies, but the caverns are typically held at or near full capacity for emergency readiness.

The math, explained without jargon

One metric tonne of crude oil works out to roughly 7.33 barrels, depending on the grade. So 5.33 million tonnes multiplied by 7.33 gives about 39 million barrels.

India consumes roughly 5.5 million barrels of crude oil per day. Divide 39 million by 5.5 million and you get about 7 days of consumption from the strategic stockpile alone. If you add the working stocks held by oil marketing companies and refiners, total emergency cover stretches to about 65 to 75 days.

The IEA standard for member countries is 90 days of net imports. India is not a full IEA member, but it is an associate, and the country is working toward that benchmark gradually.

Why the number is smaller than people expect

Many readers assume a country with 1.4 billion people and rapid energy demand growth would hold massive reserves. The current figure looks modest because:

• Underground caverns are expensive to build, with each site costing thousands of crore rupees
• Filling reserves at high oil prices is politically and financially painful
• India lacked the foreign exchange muscle to build large reserves through the 2000s
• The strategic reserve programme only started serious construction in the late 2000s
• Day-to-day buffer stocks at refineries reduce the urgency for very large strategic caverns

By contrast, the United States Strategic Petroleum Reserve has held over 700 million barrels at peak levels, while China is estimated to hold over 700 million barrels across multiple sites. India is starting from a much smaller base.

The Phase II expansion plan

The government has approved a Phase II expansion to add about 6.5 million tonnes (roughly 47 million barrels) at two new locations:

• Chandikhol, Odisha — proposed capacity of 4 million tonnes
• Padur (Phase II) — proposed additional capacity of 2.5 million tonnes

Once Phase II is operational, the combined storage will rise to nearly 12 million tonnes or roughly 87 million barrels. Adding refinery and pipeline working stocks, total cover would approach the 90-day IEA benchmark.

Construction timelines have slipped multiple times, partly due to land and tendering delays. Targeted commissioning has been pushed to the second half of this decade for the new caverns.

Why this matters for energy security and the market

India imports about 87 percent of its crude oil. Any disruption in the Strait of Hormuz, the Bab-el-Mandeb Strait or major Gulf producers can hurt fuel supply within days. The strategic reserves are the country's first line of defence during such a shock.

For energy markets, the SPR also acts as a buyer of last resort. When global prices crashed in 2020, India accelerated SPR fills at low prices, locking in cheap inventory. That kind of countercyclical buying saves billions in the long run, though it requires fiscal headroom to act fast.

How SPRs interact with global crude prices

Strategic reserves rarely move physical prices, but they shape market psychology. When the United States announced large SPR releases in 2022, the headlines themselves nudged global prices lower for weeks. India's reserves are too small to influence world prices in the same way, but they do influence domestic fuel availability and refinery scheduling during a crisis.

For Indian refiners, the SPR also functions as a long-term supplier-of-flexibility. When a contracted supply is delayed, refiners can lift from strategic stocks and replace later when global prices ease.

Frequently Asked Questions

How many days of oil consumption do India's SPRs cover?

About 9 to 10 days at current consumption rates. Once Phase II is complete, that number will more than double.

Who owns the oil stored in India's strategic reserves?

The Indian government, through Indian Strategic Petroleum Reserves Limited. Some space has historically been leased to foreign producers under tolling arrangements, with first right of refusal to the Indian government during emergencies.

Are India's reserves part of the IEA system?

India is an IEA Association country, not a full member. It coordinates with the IEA on emergency response but is not bound by the 90-day mandatory cover rule that applies to full members.

Where can I see the latest SPR data?

The Petroleum Planning and Analysis Cell publishes periodic updates on stocks and consumption, and you can verify ministry-level numbers on official portals such as the International Monetary Fund commodity data pages.
