title: America’s strategic oil buffer is rapidly disappearing.
description: "The U.S. Strategic Petroleum Reserve (SPR) fell by another 6.1 million barrels last week, dropping to 298.7 million barrels.\n\nThat pushes the reserve below 300 million barrels for the first time since January 1983, and to its lowest level in more than 43 years.\n\nThe pace of depletion is also accelerating:\n\n• Previous week: -2.8 million barrels\n• Latest week: -6.1 million barrels\n\nSince the Iran war began, Washington has relied heavily on the SPR to offset disruptions to global oil supplies and limit upward pressure on crude prices.\n\nBut that strategy has a limit.\n\nThe reserve is now entering the estimated 250–300 million barrel operational floor, where extracting additional oil can become increasingly difficult.\n\nAt the current pace of withdrawals, the U.S. could move deeper into that critical range within weeks.\n\nThe SPR was built as America’s emergency energy insurance policy.\n\nThat insurance policy is getting dangerously thin.\n\nSource: Global Markets Investor, zerohedge"
