U.S. Strategic Petroleum Reserve at 282.683 Million Barrels as New Exchange Reaches 40 Million

Key Facts

1The U.S. Strategic Petroleum Reserve held 282.683 million barrels in the week ended October 16, 2026.
2The Department of Energy offered an exchange of up to 40 million barrels, as part of a U.S. commitment to release 172 million barrels and an overall international pledge of 400 million barrels.
3Total U.S. crude oil, including the reserve, stood at 695.2 million barrels, while commercial stocks were 412.517 million barrels on October 16, 2026.
4On October 23, the Department of Energy authorized an emergency exchange of up to 400,000 barrels for a Louisiana refinery.

The U.S. Strategic Petroleum Reserve held 282.683 million barrels in the week ended October 16, 2026, according to data from the U.S. Energy Information Administration. The reading comes as the Department of Energy carries out an exchange program offering up to 40 million barrels from the reserve. The department said the program is part of fulfilling a previous U.S. commitment to release 172 million barrels, coordinated with a total pledge of 400 million barrels from International Energy Agency member countries. The exchanges are intended to bring supplies to market to address short-term disruptions and strengthen energy security, the department said. The public data do not describe the October reading as a historical low; the series shows stocks at 280.802 million barrels on October 15, 1982, then 283.393 million a week later.

U.S. Energy Information Administration data show total U.S. crude oil, including the Strategic Petroleum Reserve, stood at 695.2 million barrels on October 16. Commercial crude stocks, a separate measure that excludes the reserve, reached 412.517 million barrels. The reserve therefore held 282.683 million barrels in the weekly series, while the Department of Energy reports a total of 282.2 million barrels in its site-by-site breakdown for the same period. The difference between the two figures reflects their presentation and update sources: the weekly series records total stocks, while the site table provides a separate breakdown. Distinguishing the reserve from commercial stocks highlights that the two figures measure different holdings within total U.S. crude.

The reserve is stored in underground salt caverns across a federal network of four sites on the Gulf Coast in Texas and Louisiana. Its authorized storage capacity is 714 million barrels, according to the Department of Energy. Stocks reached full capacity on December 27, 2009, after a final shipment that began its journey on Christmas Day arrived, the department said. Authorized capacity allows the current stock level to be compared with official storage capabilities, but does not mean all capacity is occupied. The department describes the reserve as an emergency stockpile of crude oil, while current exchanges are used to deliver supplies during short-term disruptions.

On October 23, the Department of Energy authorized an emergency exchange of up to 400,000 barrels for a Phillips 66 refinery in Lake Charles, Louisiana. The department said the volume would be drawn from the West Hackberry site for immediate delivery. The measure aims to offset a temporary disruption in crude supplies to the refinery and support continued transportation-fuel production. The department added that the borrowed oil would be returned with additional barrels. The action is part of using exchanges to meet specific supply needs, alongside the broader program announced in September.

The Department of Energy said companies participating in the September program would return 40 million borrowed barrels, plus premium barrels. It said previous exchanges had returned volumes 25% above the barrels withdrawn. Volumes awarded under the exchanges are scheduled for delivery in November and December 2026. The current withdrawal is therefore tied to an arrangement to return oil to the reserve with an increase, under the terms of the program announced by the department. The upcoming delivery dates are the next milestone in carrying out the planned exchanges.

The Energy Information Administration typically releases its weekly petroleum report on Wednesday at 10:30 a.m. Eastern time. The agency set October 28, 2026, as the next release date. The report is expected to provide an updated reading on U.S. oil stocks, including the reserve and commercial inventories. The American Petroleum Institute's page says its bulletin is typically released on Tuesday afternoon and does not list a confirmed date specifically for October 27. The EIA report on October 28 therefore remains the next date officially listed on its schedule.
