India’s “8-week buffer”: Carnegie India flags structural risks in oil security

Summary

• A report by Carnegie India estimates India’s total oil cover at around 50–60 days, significantly lower than peers like China and Japan.
• India’s refining system is optimized for medium-to-heavy crude, limiting flexibility to switch quickly to lighter grades during supply disruptions.
• Experts recommend a hybrid strategic-commercial storage model to expand reserves without placing the full financial burden on the government.

NEW DELHI, April 14, 2026 — A new analysis by Carnegie India has raised concerns over India’s oil security framework, warning that the country remains structurally vulnerable to prolonged disruptions in global crude supply—particularly from West Asia.

The storage gap

India’s energy security buffer is a combination of Strategic Petroleum Reserves (SPR) and commercial inventories held by refiners and oil marketing companies.

According to the report:

• India’s SPR capacity covers roughly 9–10 days of demand, based on current storage levels.
• When combined with commercial stocks, total oil cover rises to about 50–60 days (around 7–8 weeks).

This remains below the 90-day benchmark recommended by the International Energy Agency for energy security preparedness.

In comparison, countries such as Japan and China maintain significantly larger buffers due to long-term investments in storage infrastructure and coordinated stockpiling strategies.

Refinery configuration constraints

Beyond storage, the report highlights a structural limitation in India’s refining ecosystem.

Many Indian refineries—operated by firms like Indian Oil Corporation and Bharat Petroleum Corporation Limited—are configured to process medium and heavy crude grades, commonly sourced from the Middle East and Russia.

This creates a degree of “crude lock-in”:

• Switching to lighter crude (e.g., from the U.S. or West Africa) may reduce efficiency
• Diesel and distillate yields could be impacted
• Technical adjustments require time and capital investment

While Indian refineries are generally considered complex and flexible by global standards, rapid large-scale substitution is not seamless.

Rethinking storage: a hybrid model

To strengthen resilience, Carnegie India proposes a “commercial-strategic hybrid” model for expanding reserves.

Under this approach:

• Global oil producers (such as national oil companies) could lease storage space in Indian caverns
• The oil would remain commercially owned but accessible to the Indian government during emergencies
• This would reduce upfront public investment while increasing total available reserves

India has already experimented with similar arrangements in limited form, but scaling it could accelerate SPR Phase II expansion.

Why this matters

• Energy vulnerability: A relatively smaller buffer increases exposure to supply shocks, especially in volatile regions like the Strait of Hormuz.
• Economic sensitivity: Oil disruptions can quickly translate into higher fuel prices and inflation in an import-dependent economy.
• Policy urgency: Expanding storage and diversifying crude sourcing are becoming central to India’s long-term energy strategy.

FAQs

Q1. Where are India’s strategic oil reserves located?

India’s Phase I SPR facilities are located at Visakhapatnam, Mangaluru, and Padur, with a combined capacity of about 5.3 million metric tonnes.

Q2. Why hasn’t India built larger reserves already?

Constraints include high capital costs, land acquisition challenges, and budget prioritization, though expansion plans are ongoing.

Q3. Does this mean India is at immediate risk of fuel shortages?

No immediate risk is indicated. However, prolonged global disruptions could tighten supply and raise costs, given the current buffer levels.
