FX.co ★ U.S. API Crude Inventories Surge, Posting Sharp Build to 9.072M Barrels

U.S. crude oil inventories recorded a sharp increase in the latest weekly data, with American Petroleum Institute (API) figures showing a build of 9.072 million barrels, up from a previous rise of 2.690 million barrels. The updated data were released on 11 August 2026.

The substantial jump in stockpiles suggests a markedly looser balance between supply and demand compared with the prior reading. While the earlier figure pointed to a moderate build, the latest number indicates a significantly stronger accumulation of crude in storage across the United States.

Market participants will be watching subsequent official data and upcoming weeks’ readings to assess whether this surge in inventories reflects a temporary fluctuation or a developing trend in U.S. oil market fundamentals.
