FX.co ★ US Crude Oil Inventories Swing Back to Build, Rising 2.969M Barrels

US crude oil inventories reversed course, posting a build of 2.969 million barrels after a prior draw of 0.640 million barrels, according to data updated on 23 September 2026. The latest figure marks a notable change in direction from the previous decline in stockpiles.

The shift from a modest drawdown to a sizable increase in crude inventories may signal a loosening in near-term supply-demand conditions in the US oil market. While the earlier decrease suggested stronger draw or tighter supply, the current build points to either softer demand, higher production, or a combination of both.

Market participants will be watching subsequent weekly reports closely to determine whether this inventory build is the start of a new trend or a temporary fluctuation, as changes in US crude stock levels can influence price expectations and trading strategies across global energy markets.
