US Strategic Petroleum Reserve levels have declined sharply to 285 million barrels as of the week ending September 11, 2026—the lowest since late 1982—driven by the ongoing execution of a 172-million-barrel release program coordinated with the IEA to address 2026 Middle East supply disruptions. Weekly EIA draws have averaged several million barrels in recent months, with the latest report showing a 0.4 million barrel reduction amid commercial crude stocks holding near 423 million barrels. Trader focus centers on whether the pace of these policy-driven outflows sustains through late October, with the next inventory update due September 23 and no announced refilling schedule altering the trajectory.
