U.S. crude oil inventories at the Cushing, Oklahoma storage hub increased to 1.564 million barrels, up from a previous level of 0.881 million barrels, according to data updated on 4 March 2026. The rise in stocks at Cushing, the delivery point for West Texas Intermediate (WTI) futures, suggests a loosening in physical supply conditions at the key benchmark hub.
The build in inventories may reflect stronger inflows, softer refinery runs, or a combination of both, and will be closely monitored by traders as an indicator of underlying market balance. Changes at Cushing can influence WTI futures pricing and spreads, with higher inventories typically associated with reduced immediate supply tightness. Investors and analysts will now watch subsequent weekly data to determine whether this increase marks the start of a broader stock-building trend or a short-term fluctuation in U.S. crude logistics.
