The United States has announced plans to release 172 million barrels of oil from its Strategic Petroleum Reserve (SPR) as part of a coordinated effort with allies to ease rising global energy prices.
The move comes amid supply disruptions linked to the U.S.-Israeli war involving Iran, which has caused volatility in global oil markets. The release represents more than 40% of a broader 400-million-barrel emergency action organized by members of the International Energy Agency (IEA).
According to the U.S. Department of Energy, the drawdown will begin next week and continue for approximately four months.
What Is the Strategic Petroleum Reserve?
The Strategic Petroleum Reserve is the largest emergency oil stockpile in the world. It was created to protect the United States from severe supply disruptions caused by geopolitical crises, wars, or natural disasters.
Currently, the SPR holds about 415 million barrels of oil, mostly high-sulfur “sour” crude, which many U.S. refineries are designed to process.
The oil is stored in massive underground salt caverns along the coasts of Texas and Louisiana. These caverns have the capacity to store up to 714 million barrels, making the reserve a crucial buffer during global energy emergencies.
When U.S. Presidents Have Used the SPR
Throughout history, American presidents have turned to the SPR during major geopolitical crises or disruptions to global oil supplies.
Russia’s Invasion of Ukraine (2022)
In March 2022, shortly after Russia invaded Ukraine, President Joe Biden ordered the largest release in SPR history.
The U.S. released 180 million barrels of oil over six months to stabilize global markets and reduce surging fuel prices.
Although the government later began buying oil to refill the reserve, replenishment has been limited because Congress must approve additional funding for large-scale purchases.
Attack on Saudi Oil Facilities (2019)
In 2019, Yemen’s Iran-aligned Houthi rebels attacked Saudi Arabia’s Abqaiq processing facility and the Khurais oil field, temporarily cutting more than half of the kingdom’s oil production.
At the time, President Donald Trump said the United States was prepared to use the SPR if necessary. However, Saudi Arabia restored production faster than expected, and no emergency release was required.
Libya Civil War (2011)
During the Libyan civil war in 2011, global oil markets were shaken by disruptions in Libya’s crude exports.
President Barack Obama authorized the release of 30 million barrels from the Strategic Petroleum Reserve.
The decision was coordinated with the International Energy Agency, which organized an additional 30-million-barrel release from other member nations to stabilize global supply.
Operation Desert Storm (1990–1991)
One of the earliest uses of the reserve occurred during the Gulf War following Iraq’s invasion of Kuwait.
President George H. W. Bush ordered oil releases in two phases:
- October 1990: A 3.9-million-barrel test sale
- January 1991: A 34-million-barrel sale after U.S. and allied forces launched Operation Desert Storm
In total, about 21 million barrels were ultimately sold to help calm markets during the conflict.
Why the SPR Matters in Global Crises
The Strategic Petroleum Reserve is designed as a national safety net for energy security. By releasing oil during supply disruptions, the U.S. can help stabilize fuel prices, maintain domestic supply, and support global markets.
Because oil markets are highly sensitive to geopolitical events, coordinated releases with international partners often have a strong psychological and economic impact, helping reduce panic-driven price spikes.
Conclusion
For decades, U.S. presidents have relied on the Strategic Petroleum Reserve as a powerful tool during wars, geopolitical tensions, and major supply disruptions. From the Gulf War to the Ukraine conflict and current Middle East tensions, the reserve has helped stabilize global energy markets when supply shocks threaten economic stability.
While large releases can ease short-term price pressure, policymakers must also balance the need for emergency relief with maintaining sufficient reserves for future crises.
