Investing.com - Oil prices fell on Thursday in Asia after the American Petroleum Institute (API) said crude stockpiles rose sharply last week.
U.S. Crude Oil WTI Futures lost 0.8% to $52.92. International Brent Oil Futures were down 0.7% to $59.02.
The API said crude inventories rose by 10.5 million barrels to 432.5 million barrels for the week ended Oct. 11.
"An enormous U.S. inventory build hits at precisely the wrong moment when the markets are overly focused on demand devastation due to the latest run of weaker global economic data," Stephen Innes, Asia Pacific market strategist at AxiTrader, said in a note cited by Reuters on Thursday.
If confirmed by the government data, the build-up would be the biggest U.S. inventory swell since February, 2017, Innes said.
The Energy Information Aministration (EIA) weekly report is due at 10:30 AM ET (14:30 GMT). The EIA is expected to report a build of 2.88 million barrels.
Meanwhile, concerns over an escalation in the U.S.-China trade war and weak economic indicators lingered and were cited as headwind for the oil markets, although losses were limited after U.S. Treasury Secretary Steven Mnuchin said China and the U.S. are nailing down a phase one trade deal text for their presidents to sign in November.
The International Monetary Fund said this week that the U.S.-China trade war would cut 2019 global growth to its slowest pace since the 2008-2009 financial crisis.
