U.S. Strategic Petroleum Reserve Hits 43-Year Low Amid Iran Conflict
6/17/2026, 10:48:40 PM
Record Low Levels Amid War-Driven Drawdowns
Federal data released June 12 2026 show Strategic Petroleum Reserve at 340.3 million barrels, the lowest level since July 1983. Since U.S.–Israeli coalition began its war with Iran in late February 2026, the reserve has been drawn down by 75 million barrels (?18 % of capacity). Withdrawals of 8.9 million barrels from the SPR and 8.3 million barrels from commercial storage at Cushing, Oklahoma, left the hub with just 20 million barrels, a level described as operational stress.
Capacity, Past Releases and Current Numbers
The SPR, created in 1975 after the OPEC embargo, holds 714 million barrels. It fell to less than half capacity after the Biden administration released 180 million barrels in 2022 and after President Trump authorized a 172-million-barrel drawdown in March 2026, cutting the reserve by roughly 350 million barrels from its peak.
Official Statements and Policy Response
President Donald Trump announced a peace deal with Iran and said the Strait of Hormuz would reopen “immediately after” the agreement, later revising the timeline to “upon signing of Deal on Friday.” Energy Department data confirmed SPR drawdown and said releases are being used “for the purpose it was created for.” Shipping reports note the strait remained at a near standstill weeks later, and no deal text has been released. Administration aims to add 200 million barrels to SPR within a year.
Criticism and Operational Concerns
The drawdown creates a “concerning pressure point,” and Rory Johnston of Commodity Context flagged Cushing’s low inventory as operational stress. Mike Sommers, chief executive of American Petroleum Reserve, said the SPR must stay at least 20 % full and warned, “we’re raising alarm bells right now.” Gulf Oil’s Tom Kloza dismissed the alarm, saying he is not worried about the reserve’s level.
Implications for Prices and Energy Security
If the SPR falls below the 20 % threshold, a supply shock could push gasoline prices sharply higher, especially during hurricane season when Gulf production may be disrupted. The ongoing closure of the Strait of Hormuz—through which about one-fifth of global oil passes—keeps markets vulnerable to further spikes.
