The Department of Energy announced the latest offer Tuesday as part of a broader International Energy Agency response to supply disruptions caused by the Iran conflict. The SPR held just 283.8 million barrels last week, its lowest level since October 1982.
The timing is particularly significant because oil prices remain elevated. Brent traded around $103.19 per barrel Wednesday, while WTI reached roughly $90.57, even as Middle Eastern crude exports continued to recover.
U.S. Has Already Committed 172M Barrels
The 40-million-barrel offer is not a conventional permanent sale.
Companies will receive the crude as a loan and return barrels later, including a premium that can reach 24%. The U.S. committed 172 million barrels as its share of a coordinated 400 million-barrel IEA release announced in March, with the latest tender representing the final U.S. batch under that agreement.
Borrowers have until October 6 to submit proposals, while some returned barrels will not reach the reserve until late 2028.
The drawdown comes after repeated emergency releases under both the Biden and Trump administrations. That has pushed the SPR far below historical levels precisely as the Middle East remains a major source of supply uncertainty.
We have reported how Brent’s move toward and above $100 has been driven by Iran tensions, disruptions around the Strait of Hormuz and tight refined-product markets.
How Much Protection Does the SPR Still Provide?
The larger issue is how much flexibility Washington retains if the oil shock gets worse.
Brent is heading for an approximately 14% September gain, its strongest monthly advance since July, while U.S.-Iran negotiations have yet to produce an agreement capable of restoring normal flows through the region.
Saudi shipments and broader Gulf exports have recovered, but tight diesel markets and high shipping costs continue to keep pressure on energy prices.
That matters beyond the oil market. We have already documented how oil above $100 can intensify inflation and Fed risks, while a previous retreat from nearly $110 provided only temporary relief for Bitcoin and other risk assets.
