U.S. oil futures settled lower Wednesday after the government reported a weekly decrease in domestic crude supplies, the first in three weeks, but smaller than the market expected.

Concerns over energy demand also continued to pressure prices.

Looking at the inventory data from a trend standpoint, “it appears the stretch of steep draws in crude supply, which were offering fundamental price support to the oil market earlier in the summer, have abruptly ended according to the last three EIA reports, as stockpiles have actually risen modestly since late July,” said Tyler Richey, co-editor at Sevens Report Research. 

“Demand concerns linked to a potential global economic slowdown remain the No. 1 headwind for oil right now,” he added.
