The reserve release carries a repayment obligation rather than being an outright sale. A 20 million-barrel limit per company has an exception if oil remains after acceptable awards are made.
The United States is accepting bids until Tuesday, October 6, for up to 40 million barrels of crude from its Strategic Petroleum Reserve (SPR). The programme, announced by the Department of Energy on September 29, closes at 11 a.m. Central Time, or 7 p.m. in Türkiye. Deliveries to companies receiving awards are scheduled for November and December 2026.
According to the department’s announcement, the oil will come from the Big Hill and Bryan Mound sites in Texas. The tender forms part of the previously announced 172 million-barrel US reserve release; it is not a separate 40 million-barrel commitment on top of that total.
Borrowed oil must return with extra barrels
The arrangement is an exchange with a repayment obligation, rather than an outright purchase of reserve oil. Participating companies must return the borrowed crude with additional barrels at a later date. The department aims to support near-term supply while eventually replenishing the reserve with more oil than it releases.
The SPR’s official explanation specifies repayment in oil of similar quality, with the additional volume and return date governed by the contract. The initial release and subsequent repayment therefore affect supply at different times.
40 million barrels is a ceiling: No announcement confirms that contracts for the entire amount have been awarded or that the oil has been delivered. The tender document explicitly says the department is not obliged to award an exchange contract.
A 20 million-barrel limit, with an exception
The evaluation section of the request for proposals sets a 20 million-barrel limit on awards to any one company. Section B.1 includes an exception: if oil remains after all acceptable awards have been made, the department can exceed the limit at its discretion. Bids will be assessed first on the additional oil offered in repayment, then on the volume sought.
The competition therefore concerns both who receives the oil and how many extra barrels flow back into the reserve. The final companies and allocations will become clear when offers are accepted. October 6 is the deadline for collecting bids, rather than the date on which the oil enters the market.
Deliveries will determine the supply impact
For commodity markets, the key figures to follow are how much of the ceiling is contracted and how much crude is actually delivered in November and December. Treating the proposed maximum as realised supply would overstate the certainty of the announcement’s market effect.
The pressure that energy costs can exert on monetary policy also featured in Bangladesh’s latest interest-rate decision. However, this tender provides no estimate of how much the US deliveries would change oil prices or inflation. Their effect will also depend on demand and the oil supplied by other producers over the same period.
