Crude oil inventories in the U.S. Strategic Petroleum Reserve have fallen to 282.6 million barrels, their lowest level since October 1982, as Washington continues drawing on emergency stocks to address global and domestic supply disruptions.

MONTREAL (Oil Monster): The U.S. Strategic Petroleum Reserve has fallen to its lowest level in 44 years as the federal government continues using emergency crude inventories to respond to supply disruptions.
SPR stocks declined to approximately 282.6 million barrels last week, according to Department of Energy data cited by Reuters.
The reserve last held less crude in October 1982.
Much of the recent decline reflects the United States' commitment to make 172 million barrels of SPR crude available as part of a broader International Energy Agency response to disruptions in global oil supply.
The international initiative called for IEA member countries collectively to make around 400 million barrels of crude oil and petroleum products available.
DOE has structured much of the U.S. program as exchanges rather than outright sales.
Companies receiving crude through those exchanges are required to return the borrowed barrels later, generally with additional premium volumes.

The Energy Department separately authorized an emergency exchange of up to 400,000 barrels on October 23 to address a crude-supply disruption affecting Phillips 66's Lake Charles refinery in Louisiana.
The crude is being supplied from the West Hackberry SPR site.
DOE said the exchange is intended to support continued refinery operations and transportation-fuel supply in Louisiana and surrounding markets.
Phillips 66 must return the borrowed crude along with additional premium barrels.
The historically low inventory is drawing greater attention to how much additional crude can be removed under different SPR authorities.
Federal law restricts certain limited drawdowns once the reserve contains fewer than 252.4 million barrels.
That restriction does not eliminate the government's ability to use the SPR during a qualifying severe energy-supply emergency or to meet U.S. obligations under the international energy program.
The distinction is important because the reserve's declining inventory does not mean the United States is about to lose access to its emergency stockpile.

The issue is increasingly one of flexibility rather than whether the SPR can still be used.
Washington retains emergency drawdown authority, while barrels supplied through exchanges are scheduled to return to the reserve with premiums.
But with stocks at their lowest level since 1982, every additional release puts more focus on the timing of those repayments and the amount of emergency crude immediately available if another major supply disruption occurs.
The Strategic Petroleum Reserve remains a major U.S. energy-security asset, but its inventory has fallen substantially during the 2026 emergency-release program.
The key issue now is how quickly exchanged barrels return to storage as Washington continues balancing immediate supply needs against maintaining enough crude for future emergencies.
