Europe Emerges As Key Buyer Of U.S. Strategic Petroleum Reserve Oil

Last month, the International Energy Agency (IEA) announced the coordinated release of over 400 million barrels of oil from global strategic reserves to combat high energy prices amid the Middle East turmoil. The U.S. was to contribute approximately 172 million barrels of this total, with the release taking place over 120 days starting late March 2026 to help lower gasoline costs. And now reports have emerged that theTrump administration has authorized the release of millions of barrels of oil from the Strategic Petroleum Reserve (SPR), with Europe emerging as a key buyer. According to Bloomberg, the U.S. has so far released 79.7 million barrels to 12 companies, with nearly 50 million barrels going to UK’s Vortexa Ltd. Global trading houses and Big Oil companies have been the main recipients of the oil, with Trafigura receiving 21.4 million barrels; Shell Plc (NYSE: SHEL) has received 18.1 million while Marathon Oil (NYSE:MRO) and BP Plc (NYSE:BP) have purchased 9.7 million barrels and 6.0 million barrels, respectively.

According to shipping data and maritime intelligence firm Kpler, supertanker Eagle Versailles is currently en route to Rotterdam, Netherlands, carrying a cargo of approximately 2.1 million barrels of Bryan Mound medium sour crude oil. The oil is sourced from the Bryan Mound Strategic Petroleum Reserve (SPR) site in the US. The Texas SPR site holds approximately 250 million barrels of crude oil, making it the largest repository in the U.S. reserve system. The oil is also flowing to Asia and Latin America, with Peru’s state oil company purchasing a cargo of Bayou Choctaw crude in March to be delivered in May. However, the recent fall in oil prices might dampen Asian demand.

U.S. sour crude from the SPR is being offered to European buyers at discounts of about $5 per barrel relative to local grades, providing some relief as Brent crude remains elevated near $105 per barrel. The oil is being sold on an exchange basis, to be returned at a later date. A Strategic Petroleum Reserve oil exchange is a legal mechanism utilized by the U.S. Department of Energy (DOE) to address supply shortages, such as during severe weather events or pipeline disruptions. Under this mechanism, the government loans oil from the emergency stockpile to refiners or traders, who are then required to return the same quantity of crude oil plus a premium, usually additional barrels, at a specified future date.

The return of loaned oil is expected in tranches. For some 2026 loans, the DOE requires high sulfur (sour) crude to be returned by 2028 with up to 22% interest, often in sweeter, more valuable crude grades. Following the outbreak of the Ukraine conflict in 2022, the Biden administration loaned out millions of barrels, with returns delayed until 2026 to avoid market tightening. Europe was the destination of ~21 million barrels of crude from America’s SPR release four years ago, good for 10% of the total.

The U.S. SPR has a total authorized storage capacity of approximately 727 million barrels of crude oil. These reserves are stored in 60 underground salt caverns located at four sites along the Texas and Louisiana Gulf Coast, designed for long-term emergency supply. The SPR held ~415 million barrels before the release began, good for roughly 60% of total capacity.

That said, SPR releases often fail to significantly impact oil prices because they are short-term, temporary solutions deployed to address structural supply issues.
