Key Takeaways
- U.S. crude oil inventories saw a substantial and unexpected build of 13.4 million barrels for the week ended February 7, 2026, according to the American Petroleum Institute (API). This figure significantly surpassed analyst expectations for both the API and the upcoming official EIA report.
- Gasoline stockpiles also recorded a notable increase of 3.3 million barrels, indicating potentially softening demand for motor fuel [cite: tweet].
- In contrast to crude and gasoline, distillate inventories, including diesel and heating oil, experienced a draw of 2.0 million barrels [cite: tweet].
- The key storage hub at Cushing, Oklahoma, saw its crude inventories rise by 1.4 million barrels [cite: tweet].
U.S. crude oil inventories surged by an unexpected 13.4 million barrels in the week ending February 7, 2026, according to the latest data from the American Petroleum Institute (API). This significant build defies market expectations, which had anticipated a much smaller increase in crude stocks for the API report and even a draw for the upcoming official U.S. Energy Information Administration (EIA) data. The substantial rise in crude inventories often signals weaker demand or ample supply, which could exert downward pressure on oil prices.
Gasoline inventories also saw a considerable increase, rising by 3.3 million barrels over the same period [cite: tweet]. This build in gasoline stocks suggests a potential softening in demand for refined products, despite earlier analyst forecasts for a minor rise or even a decline in gasoline inventories.
Conversely, distillate stockpiles, encompassing diesel and heating oil, registered a draw of 2.0 million barrels [cite: tweet]. This reduction in distillates is broadly in line with analyst expectations for a decline, reflecting ongoing demand or tighter supply in this segment. The primary crude oil storage hub in Cushing, Oklahoma, also contributed to the overall inventory build, with its stocks increasing by 1.4 million barrels [cite: tweet]. Cushing inventories are closely watched as they represent the delivery point for West Texas Intermediate (CL=F) crude futures.
The API data, released ahead of the official EIA report, often serves as a precursor to market sentiment. Oil futures, including West Texas Intermediate (CL=F) and Brent (BZ=F), had already been experiencing some downward pressure earlier in the day as traders pared risk ahead of the inventory figures. While geopolitical tensions, particularly concerning Iran, and past supply disruptions have recently supported oil prices, this unexpected and large inventory build could shift market focus towards demand concerns. Investors in energy-related exchange-traded funds like the United States Oil Fund (USO) and the Energy Select Sector SPDR Fund (XLE) will be closely monitoring the official EIA report due on Wednesday for confirmation and further market direction.
