U.S. Crude Stocks See Largest Weekly Build in 3.5 Years

U.S. crude inventories surged 17.4 million barrels to 424.4 million in the week ended August 7, 2026 — the biggest weekly build in 3.5 years, per EIA data reported by Reuters. Weekly swings typically run a few million barrels; a double-digit build is an outlier that forces traders to rethink positions across physical and paper crude markets.
