U.S. Drains Emergency Oil Reserves to Prevent Global Supply Chain Collapse
Washington, Friday, 5 June 2026.
As the Strait of Hormuz blockade chokes global energy, the U.S. is draining its emergency oil stockpiles to near 40-year lows to keep European and Asian markets afloat.
Escalation at the Chokepoint
The global energy landscape remains fundamentally shaken following the events of June 3, 2026, when direct military clashes between U.S. and Iranian forces near the Strait of Hormuz escalated regional tensions and raised immediate concerns for global oil supply chains [4]. The fallout from this ongoing conflict has severely constricted one of the world’s most vital maritime transit routes [GPT]. During the first quarter of 2026, daily oil transit through the Strait of Hormuz plummeted by nearly 30 percent year-over-year, dropping from a historical average of 3.18 million cubic meters (20 million barrels) per day to just 2.32 million cubic meters (14.6 million barrels) per day [1].
Draining the Strategic Cushion
To stabilize global energy markets and mitigate the economic shock of the blockade, Washington is aggressively drawing down the U.S. Strategic Petroleum Reserve (SPR) [1]. According to data released by the U.S. Energy Information Administration on June 3, 2026, the SPR declined by an additional 1.27 million cubic meters (8 million barrels) during the week ending May 29 [1]. This most recent drawdown leaves the national emergency stockpile at approximately 56.8 million cubic meters (357 million barrels), which is only about half of its total authorized capacity of 113.5 million cubic meters (714 million barrels) [1]. Concurrently, domestic commercial crude inventories also fell by 1.27 million cubic meters (8 million barrels) to 69.0 million cubic meters (433.7 million barrels), sliding 3 percent below the five-year seasonal average and marking six consecutive weeks of decline [1].
Coordinated International Lifelines
Rather than outright sales, the current Trump administration is utilizing a loan mechanism to inject liquidity into the market [3]. The U.S. Department of Energy recently loaned 8.48 million barrels of crude oil from the SPR to four major energy companies—Gunvor USA, Phillips 66 Company, Trafigura Trading, and Macquarie Commodities Trading [3]. This represents the second allotment in a broader effort to curb surging fuel prices [3]. In the first batch offered last month, energy companies took down 45.2 million barrels, representing approximately 52 percent of the available offer [3].
The Diplomatic Horizon and Market Risks
While these emergency releases have successfully prevented an immediate collapse of the global energy supply chain, they are inherently finite solutions [1]. Washington is actively seeking a lasting diplomatic deal to reopen the Strait of Hormuz and halt Iran’s nuclear program [1]. However, until a geopolitical resolution is reached, the global energy market remains highly vulnerable to further supply shocks [1].
