• The Energy Department's sixth solicitation, announced September 29, 2026, offers up to 40 million barrels from the Big Hill and Bryan Mound sites. Bids were due October 6, 2026 at 11:00 A.M. Central Time, with delivery in November and December 2026.
• The Energy Department says five previous solicitations awarded more than 133 million barrels across four completed exchanges, so awards and offers are not the same number.
• The solicitation is part of a 172-million-barrel U.S. release inside a 400-million-barrel IEA commitment.
• The Energy Department describes the exchanges as returning barrels with a 25 percent premium, and says this saves taxpayers more than $3 billion.
• Rigzone reports SPR inventory of 283.8 million barrels on September 25, 2026, 39.69% of the 714-million-barrel authorized capacity. This is analysis, not trading advice.

The U.S. Department of Energy opened a sixth Strategic Petroleum Reserve solicitation on September 29, 2026, offering up to 40 million barrels, with bids due October 6 and delivery in November and December. Rigzone reported it on October 5. Energy Secretary Chris Wright said the United States "continues to lead the coordinated efforts to stabilize oil markets." The origins describe a U.S. and IEA supply measure. They contain no reaction from any Gulf national oil company.

What the sixth round adds

The sixth solicitation offers up to 40 million barrels from the Big Hill and Bryan Mound sites. The Energy Department says five previous solicitations awarded more than 133 million barrels across four completed exchanges. The origins do not say why five solicitations produced four completed exchanges. The 133 million awarded plus 40 million offered slightly exceeds the 172-million-barrel commitment, but a solicitation is an offer, and awards can come in below it.

Why these are exchanges, not sales

The Energy Department describes the program as exchanges that return barrels to the reserve with a 25 percent premium, and says this saves taxpayers more than $3 billion. Those are the department's own figures, and Rigzone repeats them. Exchanged barrels are scheduled to come back, so the program is a loan rather than a permanent sale. The cited origins do not give a return schedule.

Where the reserve stands

Rigzone reports SPR inventory of 283.8 million barrels on September 25, 2026, down 122.9 million barrels (30.2%) from a year earlier and equal to 39.69% of the 714-million-barrel authorized capacity. The article does not name the data series behind those figures, and they come from a secondary report rather than a primary inventory release. Readers should check them against the Energy Department's own inventory data before relying on them.

The IEA pledge and the gap to delivery

The Energy Department describes the U.S. release as a 172-million-barrel share of a 400-million-barrel commitment. Rigzone reports that around 325 million barrels, about 80% of the pledge, had been released as of October 3, 2026. It attributes to Wright the statement that several European members have released only a fraction of what they pledged. The 325 million figure is a Rigzone report, not a figure from the IEA or the Energy Department pages cited here.

What to watch

The next data points are the award results for the October 6 bids, the Energy Department's inventory updates, and the pace of European releases. For Gulf producers, the origins support only one narrow point: this is a stated, dated Western stock measure. Whether it affects any Gulf national oil company's pricing or volume decisions is not addressed in them, and this desk does not infer it. This is analysis, not trading advice.
