The global oil market faces a potential wave of new demand for storage as nations move to bolster their strategic reserves following recent supply shocks. During the Iran-US conflict, the near-total blockade of the Strait of Hormuz cut off a fifth of the world's crude oil and liquefied natural gas supply for over three months, pushing Brent crude prices close to $120 per barrel. The release of strategic petroleum reserves (SPR) by major nations served as a critical stabilizer, preventing the energy crisis from escalating into a more severe disaster.

The International Energy Agency (IEA) coordinated a record release of 400 million barrels of strategic crude from its 32 member countries, with the United States leading the effort. This marked the sixth such coordinated action since the IEA's founding, reinforcing the rule established after the 1973 oil crisis that mandates members hold emergency stocks covering at least 90 days of net imports.

However, countries with weak domestic reserves, such as India, Pakistan, and Thailand, suffered significant economic impacts due to the lack of a buffer. These nations were forced to rely on measures like fuel subsidies, rationing, and reduced working hours to curb consumption.

Energy analyst Ron Bousso notes that a consensus has emerged among vulnerable energy importers post-crisis: financially capable nations will aggressively expand their strategic reserves, while those with limited resources will implement more robust energy conservation and efficiency programs.

Expansion Plans Across Nations

Multiple countries have announced plans to expand storage capacity, which could generate incremental demand for up to a billion barrels of crude oil.

As the world's third-largest crude importer and most populous nation, India is projected by the IEA to become the top source of global oil demand growth before 2030. Yet, its current strategic reserves cover only about 8 days of imports. To meet the IEA's 90-day standard, India would need to add approximately 400 million barrels of inventory, an investment of around $28 billion at $70 per barrel. The country has already directed its national oil company to build new storage facilities for 1.75 million metric tons (nearly 13 million barrels), increasing emergency capacity by one-third.

Pakistan, which relies on the Middle East for 90% of its oil and gas imports, would require an additional 35 million barrels to reach the 90-day reserve target. Singapore, a key Asian refining hub, is also evaluating plans to construct new strategic storage for oil and gas.

Australia, the only full IEA member that has long failed to meet the reserve requirement, plans to invest A$7 billion to build reserves, aiming for at least 50 days of fuel stock coverage.

In Europe, existing natural gas storage primarily addresses seasonal winter shortages. With liquefied natural gas now constituting over 40% of regional supply—more than 60% of which comes from the US—the continent is considering new government-controlled oil and gas storage initiatives.

Oil-producing nations are also accelerating their storage strategies. Gulf national oil companies are establishing additional storage facilities overseas to ensure flexible export channels during crises. Saudi Aramco already operates storage hubs in Japan, South Korea, Egypt, and Northwestern Europe and plans further expansion.

Calculating the New Demand

Analyst estimates suggest that new national reserve projects could collectively create demand for approximately 500 million barrels of additional storage for crude and refined products. Furthermore, IEA data indicates that global strategic inventories have been drawn down by about 400 million barrels since the onset of the recent conflict. Even with the Strait of Hormuz reopening, stockpiling is expected to continue through the summer.

Combined, these two factors could generate nearly one billion barrels of additional global crude demand. Even if phased in over several years, this sustained inventory building would provide ongoing support for oil prices, establishing a firmer price floor.

Market Balancing Factors

However, fundamental supply and demand dynamics are expected to mitigate upward price pressure. The IEA forecasts a significant surge in global oil supply next year following the restoration of Middle East production capacity, potentially creating a daily surplus exceeding 4 million barrels. Consequently, the incremental demand from stockpiling is unlikely to drive a sharp, sustained price spike. That said, if geopolitical stability in the Middle East fractures and capacity recovery lags behind expectations, inventory purchases could once again push prices higher.

The Long-Term Outlook

From a broader perspective, the global expansion of strategic reserves will enhance the world's resilience to energy shocks and help moderate extreme price volatility. Countries like India will be better positioned to reduce spot purchases during periods of tight supply and high prices, using their reserves to smooth demand and significantly dampen the sharp, pulse-like price surges triggered by geopolitical crises.
