US Strategic Reserve at 43-Year Low After Hormuz Emergency Releases
EIA data show the SPR at 319 million barrels as of July 3, the lowest since April 1983, limiting Washington's emergency buffer.
The U.S. Strategic Petroleum Reserve fell to 319.48 million barrels in the week ending July 3, EIA data published on July 8 show, a level not seen since April 29, 1983, when holdings stood at 317.45 million barrels. Against the DOE's authorized storage capacity of 714 million barrels, the reserve is now 56 percent empty. Rigzone reported the milestone on Monday (2026-07-13).4
The weekly pace of drawdown was steep. SPR holdings declined 6.2 million barrels, or 1.9 percent, in the most recent reporting period and are down 83.5 million barrels (20.7 percent) compared with a year earlier, according to EIA's weekly petroleum status report released July 8.4
The depletion reflects a coordinated international emergency release launched in response to Middle East supply disruptions. On March 11, Energy Secretary Chris Wright announced the DOE would make 172 million barrels from the SPR available to markets. The same day, 32 IEA member countries agreed to release a combined 400 million barrels from allied emergency reserves, describing the action as addressing disruptions stemming from the region. Wright framed Washington's contribution as demonstrating President Trump's commitment to managing the SPR "responsibly."4
The proximate cause was military action on February 28 that led to what EIA's first-quarter petroleum market review called the de facto closure of the Strait of Hormuz. Prices surged toward $120 per barrel in March. The Persian Gulf had been supplying approximately 20 million barrels per day to world markets before the disruption.1,2
The emergency release helped deflate the price spike. By late June (2026-06-22), NYMEX WTI crude front-month had consolidated below $74.30 as U.S.-Iran negotiations advanced and the prospect of restored Strait flows weighed on futures, according to FX Empire analysis. On Monday (2026-07-13), WTI front-month traded at $78.00, while ICE Brent crude front-month stood at $83.25. Both remain above most pre-crisis benchmarks but well below the March highs.3
The DOE supplemented the initial commitment in May with contract awards covering the exchange of approximately 53.3 million barrels from four SPR cavern sites: Bayou Choctaw, Bryan Mound, Big Hill, and West Hackberry.4
The arithmetic is uncomfortable. The 172-million-barrel release commitment already exceeds half of the 319 million barrels currently in store. A comparable drawdown in response to a second supply shock would push the reserve toward levels requiring allied stocks from the outset, rather than as a backstop.4
Trader positioning on NYMEX WTI crude front-month reflects the expectation that supply pressure will continue easing. A bearish signal weighting of 74 percent, drawn from 39 signals, suggests the market treats the Hormuz risk premium as fading. Contrarian signals on ICE Brent crude front-month retain a bullish case at 45 percent confidence based on tail risk of renewed Strait disruption, but the balance of signals points to further consolidation barring a diplomatic breakdown.
EIA's next weekly petroleum status report, covering the week ending July 10, will show whether the SPR drawdown pace moderated after July 3. The more telling signal will be any DOE announcement on replenishment contracts: at $78 per barrel, the economics of refilling look materially more attractive than they did near the March peak near $120, and the pace of any buyback program will determine how quickly Washington rebuilds a meaningful emergency buffer.4
