US API weekly crude oil stocks fell to 3.719 million in the week ending 3 April, down from 10.263 million the previous week.
The change is a decrease of 6.544 million.
We saw the weekly crude oil stock build slow down dramatically, falling from a huge 10.263 million barrel increase to a more modest 3.719 million barrel build. This sharp deceleration is a bullish signal, suggesting the supply glut may be easing faster than anticipated. The market will now be watching the official EIA report closely for confirmation of this trend.
This smaller inventory build is likely tied to refineries increasing their activity ahead of the summer driving season. U.S. refinery utilization rates have already climbed to 91.5%, a seasonal high, as they ramp up gasoline production. This increased crude consumption is a key factor supporting oil prices, which are currently holding firm above $86 per barrel for WTI.
Given this tightening picture, we should consider positioning for higher prices through call options or bull call spreads on June WTI contracts. The data also strengthens the current market backwardation, where near-term prices are higher than future prices, rewarding those holding long positions. This structure signals immediate market tightness that traders can capitalize on.
When we look back at the spring of 2025, we saw a similar seasonal pattern, but the inventory builds were more consistent and the market was less volatile. That period was defined by concerns over a slowing economy which capped price rallies. This year’s sharper inventory shift suggests a fundamentally tighter market compared to what we experienced twelve months ago.
The significant difference between the last two weekly reports could also increase short-term price volatility. This makes options strategies that benefit from price swings, such as long straddles, potentially profitable around the upcoming official inventory report. A surprise in the EIA data could trigger a significant price move in either direction.
