India Orders Major Strategic Oil Reserve Upgrade

In a decisive move to strengthen its energy security amid recent global supply disruptions, the Indian government has directed state-owned Oil and Natural Gas Corporation (ONGC) to construct and fill a new underground strategic petroleum reserve (SPR) cavern at Mangaluru in Karnataka. The project, estimated at around $1.6 billion, will add 1.75 million metric tons (MMT) of crude oil storage capacity—roughly a one-third increase to India’s existing dedicated SPR infrastructure.

This announcement comes in the wake of the Iran-related conflict and ensuing oil supply crisis, which exposed India’s vulnerabilities as the world’s third-largest oil consumer and a nation that imports over 85-90% of its crude needs. Soaring energy import bills and rising fuel prices have accelerated long-standing plans to bolster reserves.

Current Capacity and the Scale of the ChallengeIndia’s existing SPR facilities—located at Visakhapatnam (Andhra Pradesh), Mangaluru, and Padur (both in Karnataka)—currently hold a total capacity of 5.33 MMT of crude oil, equivalent to approximately 39 million barrels. This provides roughly 8 days of coverage based on India’s daily crude consumption of around 5.3–5.5 million barrels per day.

This is modest compared to major global players. For context:

The United States Strategic Petroleum Reserve (SPR) currently holds about 340 million barrels (down significantly from higher levels earlier in 2026 due to releases), with an authorized capacity of 714 million barrels.

China maintains the world’s largest combined strategic and commercial oil inventories, estimated at nearly 1.4 billion barrels as of late 2025 (with government-held portions around 360 million barrels).

Japan holds substantial government strategic inventories of around 263 million barrels.

India’s current dedicated SPR is well below the International Energy Agency’s (IEA) recommended 90-day import coverage target for member countries, highlighting the urgency of expansion.

Broader Expansion Plans and International Partnerships

The new Mangaluru facility builds on India’s Phase II SPR expansion program, which includes:

• A 4 MMT facility at Chandikhol in Odisha.
• A 2.5 MMT expansion at the existing Padur site.

These projects, once completed, would raise India’s dedicated SPR capacity to approximately 11.83 MMT (roughly 87 million barrels), providing closer to 15–22 days of coverage depending on consumption levels.

Further momentum comes from a May 2026 strategic collaboration agreement between Indian Strategic Petroleum Reserves Limited (ISPRL) and Abu Dhabi National Oil Company (ADNOC). The deal explores expanding ADNOC-linked crude storage in India up to 30 million barrels, including existing facilities at Mangaluru and potential new sites at Visakhapatnam and Chandikhol. It also includes potential storage linkages in Fujairah tied to India’s SPR system, alongside LNG and LPG cooperation.

Additional concepts under consideration include large salt cavern storage at Bikaner in Rajasthan (around 5.2–5.3 MMT).

A Tale of Two SPR Strategies: US vs. China

The recent global supply stresses have highlighted contrasting approaches to strategic reserves:

United States: America has actively released oil from its SPR (including hundreds of millions of barrels in coordinated actions tied to the Iran conflict) to increase supply in global markets. This helped moderate price spikes and supported refiners and consumers worldwide. However, it has drawn the SPR down to multi-decade lows around 340 million barrels.

China: Beijing took a different path by aggressively building inventories in 2025 (adding an average of ~1.1 million barrels per day) and maintaining large stockpiles. During disruptions, China could draw from these reserves rather than making large additional purchases on the open (spot) market—reducing demand pressure and helping stabilize global prices from the consumption side.

Both strategies ultimately supported market stability, but through opposite mechanisms: one adds barrels to supply, the other avoids adding to demand.

India’s Path: Energy Security Starts at Home

India’s latest move aligns perfectly with the principle articulated by Stu Turley, host of the Energy News Beat Podcast: “Energy Security Starts at Home, and your Energy Dominance is displayed through your exports.”While the United States demonstrates energy dominance through record production and exports, India is prioritizing foundational security by building a robust domestic buffer. A larger SPR will allow India to better weather future supply shocks—such as disruptions in the Strait of Hormuz—without aggressive spot-market buying that could exacerbate global price volatility. In a crisis, India could draw down reserves to meet domestic needs, acting as a demand stabilizer similar to China’s approach, while continuing its role as a major refiner and product exporter.

This trend toward greater energy resilience is visible globally. IEA members have coordinated reserve releases during crises, Japan maintains one of the largest stockpiles relative to consumption, and other nations are reassessing vulnerabilities in an era of geopolitical tension.

What It Means for Global Markets

India’s expanded reserves—potentially reaching well over 100 million barrels when including Phase II, ADNOC-linked storage, and other plans—will not only enhance national security but could also contribute to calmer global oil markets. By reducing the need for panic imports during disruptions, India joins China in helping smooth demand spikes that have historically amplified price swings.

As geopolitical risks persist, the message is clear: countries are doubling down on strategic reserves. India’s upgrade is a pragmatic, forward-looking step that strengthens its position while supporting broader market stability.

Energy security is no longer optional—it’s foundational.
