September 11, 2026. According to OK Energy Today, throughout the month of August, the inventory fluctuated around 21 million to 22 million barrels of oil.
Cushing Hub inventories stayed critically tight: EIA put stocks at 21.824 million barrels as of Sept. 4, down from 22.508 million a week earlier and far below the hub’s ~73–75 million-barrel tank farm capacity.
Crude is not building in storage; it is being pushed through northern Oklahoma toward Gulf Coast refineries and export terminals, a flow the article ties to tight global supply from the U.S.–Israel war with Iran.
August inventories hovered around 21–22 million barrels; the recent low was 18.757 million on June 19 and the 2026 high was just over 31 million on April 3.
The hub remains the WTI futures delivery point and a pipeline crossroads: nearly two dozen inbound/outbound lines with more than 6.5 million b/d of capacity move crude from Western Canada, the Permian, Bakken, and Rockies.
Those barrels are then redirected to landlocked Midwest refineries or south to Gulf Coast export terminals—so low tank levels at Cushing signal a throughput-heavy supply chain, not idle storage.
