FX.co ★ US API Crude Stocks Swing Sharply Back to Surplus at +13.4M Barrels

U.S. crude oil inventories tracked by the American Petroleum Institute (API) posted a sharp reversal in the latest weekly data, shifting from a steep drawdown to a substantial build. According to figures updated on 10 February 2026, API Weekly Crude Oil Stock rose by 13.400 million barrels, compared with the previous reading of a 11.100 million barrel decline.

The move from a large draw to a sizeable build highlights a pronounced change in the weekly supply-demand balance for U.S. crude. Such swings in inventories can influence market expectations around domestic supply conditions and, in turn, shape short-term sentiment in oil prices and energy-related assets.

With traders and analysts closely watching U.S. stock levels as a gauge of underlying demand and production trends, the latest API data will likely feed into positioning ahead of other key market indicators and official government inventory reports.
