Energy Department officials issued a request for proposals on Sept. 29, 2026, for an exchange of up to 40 million barrels of crude oil from the Strategic Petroleum Reserve, and bids closed at 11:00 a.m. Central Time on Tuesday, Oct. 6. The oil comes from the reserve’s Big Hill and Bryan Mound sites on the Texas Gulf Coast.
Energy Secretary Chris Wright framed the offer as part of a coordinated international effort, saying the United States “continues to lead the coordinated efforts to stabilize oil markets.” The department had announced no award for this solicitation as of Oct. 9.
The Sept. 29 request for proposals
The department’s release says the solicitation continues the execution of the 172-million-barrel release President Trump announced, which forms part of the 400-million-barrel commitment by member nations of the International Energy Agency. It adds that the action builds on five previous solicitations that collectively awarded more than 133 million barrels across four completed exchanges, and that earlier exchanges returned barrels at a 25 percent premium. The department said those exchanges also showed the reserve can deliver crude quickly, which is the case it made for using the exchange tool again rather than a conventional sale.
Wright also pressed other IEA members in the release, urging every member country to fulfill its commitments. He noted that Japan and the United States are delivering on theirs, while several European members have released only a fraction of what they pledged.
The previous solicitation in the series, a June 10 request for proposals that the department described in its own release, also offered up to 40 million barrels from Big Hill and Bryan Mound, with bids due June 15. Curt Coccodrilli, the department’s acting assistant secretary for hydrocarbons and geothermal energy, said then that the exchange “will help move oil swiftly to refiners, ease short-term supply pressures.”
Exchange mechanics and the Big Hill and Bryan Mound caverns
An exchange is a loan, not a sale. Under the department’s description, participating companies borrow the crude and return the 40 million barrels plus additional premium barrels, so the reserve ends up with more oil than it released. The department says the structure supplies the market now while adding to the reserve’s long-term inventory at no cost to taxpayers. The department’s program page says the reserve has an authorized storage capacity of 714 million barrels at four Gulf Coast sites and that the Secretary of Energy’s exchange authority is separate from the presidential authority for emergency sales under the Energy Policy and Conservation Act.
The two sites named in the solicitation are both salt-cavern facilities in Texas. According to the department’s storage-site descriptions, Big Hill in Jefferson County, about 26 miles southwest of Beaumont, has 170.0 million barrels of authorized storage across 14 caverns. Bryan Mound in Brazoria County, about three miles southwest of Freeport, has 247.1 million barrels across 19 caverns. Oil moves in and out by displacement, since it floats on the water used to push it. The department calls salt caverns the most secure and lowest-cost storage among the reserve’s facilities, and both sites became operational decades ago, Bryan Mound in 1986 and Big Hill in 1991.
The November and December delivery sentence
The delivery language in the release is narrow. It states: “Deliveries under awarded exchanges are scheduled for November and December 2026.” The sentence sits in the paragraph that describes the five earlier solicitations and does not say in so many words that it governs the 40 million barrels just offered.
Trade coverage read it more broadly. Rigzone, in an Oct. 5 report, listed the delivery months for the latest solicitation as November and December 2026, and reported no award yet. The department’s text supports the schedule for exchanges that have been awarded; whether the new barrels flow on the same calendar depends on awards the department had not announced.
The exchange lands while the reserve is low. Roic.ai, summarizing the solicitation, reported that the reserve held less than 284 million barrels in late September, its lowest level since 1982, and that borrowed barrels are not expected to be fully returned until late 2028. Those are the outlet’s figures rather than the department’s, and the release itself states only the 25 percent premium achieved on earlier exchanges. A June 10 release from the department put the premium on earlier exchanges at 26 percent, so the two releases differ by a point on the same history.
The department has not named bidders, volumes or companies for the 40-million-barrel solicitation. Bids for the June offer were due June 15, and the release for this one gives Oct. 6 as the only dated step after issuance, which leaves the award date, the premium negotiated and the final volume as the unpublished figures.
