Strategic Petroleum Reserve (SPR) Capacity
The U.S. SPR, the world’s largest emergency crude oil stockpile, has an authorized capacity of approximately 714–715 million barrels, with actual inventory around 415 million barrels following the March 2026 emergency release during the U.S.-Israel conflict with Iran . The SPR can be drawn down at a maximum rate of 4.4 million barrels per day, which means that, if used alone, it could supply oil for roughly 94 days at full drawdown capacity However, this rate is insufficient to fully offset major global supply disruptions, such as the closure of the Strait of Hormuz, which blocked 11–16 million barrels per day
Total U.S. Oil Reserves
Beyond the SPR, the United States holds tens of billions of barrels in proven underground reserves, primarily in Texas, New Mexico, North Dakota, Alaska, and the Gulf of America . These reserves, combined with commercial inventories, support a daily crude production capacity of over 12 million barrels . Under normal domestic consumption and production patterns, these reserves could sustain U.S. oil needs for several months to over a year, depending on consumption rates, production adjustments, and emergency drawdowns.
