The Department of Energy reported Monday that the Strategic Petroleum Reserve (SPR) fell to 340.3 million barrels, marking the smallest inventory level recorded since 1983.
The most recent reduction was 8.9 million barrels, which the agency identified as the third steepest draw in the SPR's recorded history. That draw is one component of a broader, planned release of 172 million barrels announced in March by the Trump administration.
According to the Energy Department, the release was coordinated with partner nations and occurred less than two weeks after the United States and Israel launched attacks on Iran. Officials said the move was intended to help address rising fuel prices that resulted from the war in Iran.
If the full 172 million-barrel program is carried through, the department says the reserve will be reduced to about 243 million barrels, which it describes as roughly one-third of the stockpile's authorized capacity. The department alsonotes that such a full release would represent the second-largest drawdown in the reserve's history.
The SPR was created following the Arab oil embargo of the early 1970s. The Energy Department spokesman reiterated that the administration is deploying the reserve in line with its intended purpose - to help stabilize oil markets and to protect the United States from supply disruptions.
The ongoing drawdown coincides with diplomatic developments: the United States and Iran reached an interim peace agreement that will reopen the Strait of Hormuz and begin steps toward ending what the department described as a 15-week war.
To execute the release, the administration is using an exchange program. Under that arrangement, private companies borrow barrels from the SPR and are obligated to return them with interest. The Energy Department spokesman reported that the return rate on borrowed barrels has reached about 26 percent, a figure the department said has generated more than $3 billion in savings for taxpayers.
Looking ahead, the agency outlined plans to refill the reserve within the next year. The department stated it intends to replenish the stockpile with approximately 200 barrels, described as 20 percent more than what was released.
Context and immediate implications
The reported decline to 340.3 million barrels and the authorization of a large-scale coordinated release underline a policy choice to use the SPR actively in response to short-term price pressures linked to geopolitical conflict. The exchange mechanism used to deliver oil into markets has delivered measurable taxpayer savings via returned barrels with interest, per the Energy Department spokesman.
The department's stated plan to partially refill the reserve within a year was presented alongside the acknowledgment that, if the release is completed as planned, the reserve would be left at roughly one-third of its capacity - a level not seen since the early 1980s.
What the department has said
"The administration is using the reserve as intended to help stabilize oil markets and protect the US from supply disruptions," an Energy Department spokesman said.
Additional details provided by the Energy Department include the role of international coordination in the release decision, the timing of the release relative to military actions in the region, and the mechanics and fiscal outcome of the exchange program. The department's statements also note an interim diplomatic development between the United States and Iran aimed at reopening a critical shipping lane and moving toward an end to the 15-week conflict.
