US Strategic Reserve More Than Half Depleted as DOE Advances IEA Emergency Drawdown
The SPR is 56% empty as the US executes the IEA's record 400 million barrel emergency release following the Iran war supply disruption.
The U.S. Strategic Petroleum Reserve is more than half empty. A Department of Energy announcement on July 13 (2026-07-13) confirmed the SPR had dropped to 56% depleted, marking what the agency called "the next phase" of the United States' 172 million barrel contribution to the International Energy Agency's emergency release programme, Rigzone reported. ICE Brent crude front-month held at $80.16 per barrel on Wednesday (2026-08-05), off 0.58%, while NYMEX WTI front-month traded at $75.90, down 0.24%.4
The drawdown is part of the IEA's largest-ever coordinated emergency stockpile release, agreed in March 2026 after the Iran war disrupted global energy flows and triggered sharp oil price spikes. The IEA's 32 member countries committed to releasing 400 million barrels of oil and refined products in total. The United States is carrying the bulk of that burden, with the Trump administration authorising 172 million barrels from the SPR, a figure comparable to the 180 million barrels released under the Biden administration between 2022 and 2023.7,5
Execution has been rapid. Between the week ending March 20 (2026-03-20) and the week ending April 24 (2026-04-24), the DOE had already pushed 17.5 million barrels onto the market, EIA data showed. On May 11 (2026-05-11), DOE announced contract awards for the exchange of approximately 53.3 million barrels from the Bayou Choctaw, Bryan Mound, Big Hill, and West Hackberry sites. The July 13 announcement confirmed the programme was advancing through its next tranche.6,4
The supply disruption driving those releases has no modern equivalent. IEA Executive Director Fatih Birol told CNBC on Thursday (2026-05-14) that the world had "lost 13 million barrels per day of oil," calling it "the biggest energy security threat in history." The Strait of Hormuz, through which roughly 20 million barrels of oil and petroleum products moved daily before the conflict, was blocked. Europe, which had sourced around 75% of its jet fuel from Middle East refineries, saw that supply fall to essentially zero.1
Global inventories reflected the severity. IEA data showed on-land commercial and strategic stockpiles fell by more than 250 million barrels between March and May 2026, draining at a record pace. OilPrice.com reported in early June (2026-06-02) that the IEA was warning markets could enter a "red zone" through July and August as those draws met peak summer demand. The Strait of Hormuz closure had removed roughly 10% of global oil supply, making it the largest supply shock in recorded history, the IEA said.3
Current crude prices sit well below what that scale of supply loss might imply. Demand-side weakness from Asia has done much of the work to suppress the price signal. China's oil imports fell to a 10-year low in April, as refiners processed cheaper stocks accumulated before the war rather than seeking new cargoes, Energy Aspects data showed. Asian crude processing was expected to drop 5.6% to 28.7 million barrels per day in May from March levels — a drag running counter to the supply disruption narrative.2
Some traders are positioned for a rebound. Contrarian bullish signals in both ICE Brent and NYMEX WTI front-month contracts are tied to storage arguments and continued geopolitical risk from the unresolved Iran conflict. But those signals are outnumbered when measured against the broader bearish complex.
Each barrel leaving the SPR now is unavailable for the next crisis. The Trump administration's 172 million barrel commitment is comparable in scale to the largest prior US strategic release. The DOE's July 13 (2026-07-13) announcement confirmed the programme is still running, with no completion timeline given.4,7
India's response to the same supply shock illustrates the global reassessment of strategic buffer adequacy. State-owned ONGC announced plans to build a 1.75 million metric ton facility, approximately 13 million barrels, at Mangalore, where its refining subsidiary already operates a 300,000 barrel-per-day plant. India's existing operational reserve of 5.33 million metric tons, roughly 39 million barrels, covers only 8 to 9 days of net oil demand, a number that looked inadequate once the Hormuz blockade took hold. India imports over 80% of its oil, Reuters reported.7
With the US reserve now more than half empty and the Iran disruption ongoing, any further escalation would meet a meaningfully reduced strategic buffer. The IEA's flagged "red zone" period for July and August is here; how much of the inventory squeeze the coordinated release has actually prevented will be visible in crude price action over coming weeks.3,4
