Oil prices slip after rise in U.S. crude oil stocks | Reuters

Oil prices slipped on Thursday after an unexpected rise in U.S. crude oil inventories and as rising COVID-19 infections threaten demand, but prices held on to most of their gains from the previous session on expectations that supplies will remain tight through year-end.

Brent crude fell 11 cents, or 0.2%, to $72.12 a barrel at 0644 GMT, after rising 4.2% in the previous session. U.S. West Texas Intermediate (WTI) crude fell 6 cents, or 0.1%, to $70.24 a barrel, after rising 4.6% on Wednesday.

"Volatility in energy remains elevated as traders grapple with short-term demand weakness from Delta variant concerns and expectations the crude deficits will last till the end of the year," said Edward Moya, senior analyst at OANDA.

"Oil will struggle to recoup all of its losses until the trend of new curbs or restrictions starts to ease across Southeast Asia, Australia, and Europe," he said.
