US commercial crude inventories fell by 4.45 million barrels in the week ending August 21, 2026, according to the Energy Information Administration, exceeding analyst estimates centered on a draw of about 4 million barrels. The decline followed a modest build of roughly 95,000 barrels the previous week and reinforced a broader pattern of drawdowns during 2026. Commercial stocks outside the Strategic Petroleum Reserve have fallen to levels not recorded in years, pressured by refinery utilization frequently exceeding 95%, elevated US crude exports and late-August peak driving-season demand. The SPR has declined to between 286 million and 307 million barrels, multi-decade lows not seen since the 1980s, reducing the government’s ability to release emergency supplies during a disruption. Larger-than-expected inventory draws generally support oil prices, with WTI and Brent often reacting within minutes of EIA data. The next report, scheduled for September 2, 2026, will be watched for evidence of whether the latest draw was unusual or part of the continuing trend. Market participants are also monitoring refinery throughput, export volumes and global demand, particularly in major Asian consuming economies.
