The Energy Information Administration reported on Wednesday that U.S. crude oil stockpiles rose modestly in the week ended August 21, even as inventories of key refined fuels fell.
Crude oil inventories increased by 95,000 barrels to stand at 428.9 million barrels. That build was noticeably smaller than analyst expectations, which had been for an increase of 597,000 barrels.
At the Cushing, Oklahoma delivery hub, inventories expanded by 1.2 million barrels during the week, according to the EIA data.
Refinery activity showed a mixed signal: refinery crude runs were down by 2,000 barrels per day, while overall refinery utilization edged higher by 0.2 percentage points to 97.4%.
Fuel stocks moved in the opposite direction to crude. Gasoline inventories fell by 2.5 million barrels to 206.8 million barrels. That draw exceeded analyst forecasts, which had pointed to a 0.7 million-barrel decline.
Distillate stocks, a category that includes diesel and heating oil, declined by 2.2 million barrels to 103.4 million barrels. Analysts had expected distillates to fall by 1.6 million barrels.
This weekly snapshot shows a small crude build accompanied by sharper-than-anticipated draws in gasoline and distillates, and a refinery sector that reported a slight reduction in crude throughput even as utilization rates moved up marginally.
Markets and industry participants will note the divergence between the modest crude accumulation and the larger declines in fuel inventories, as well as the sizable increase in stocks at the Cushing hub during the reported week.
Because the EIA figures for the week ending August 21 combine movements across crude, refined products, and refinery operations, the data provide a compact view of supply-side dynamics for crude and fuels within that reporting period.
