Prices for U.S. benchmark oil futures settled with a gain Wednesday, at a nearly one-week high, after U.S. government data revealed the biggest weekly decline in U.S. crude supplies since January.
Global benchmark Brent crude prices, however, finished lower as traders monitored comments from major oil producers gathering for the much-anticipated Organization of the Petroleum Exporting Countries meeting at the end of the week.
The U.S. Energy Information Administration reported Wednesday that crude supplies dropped by 5.9 million barrels for the week ended June 15. Analysts surveyed by S&P Global Platts had forecast a fall of 3.7 million barrels, while the American Petroleum Institute on Tuesday reported a decline of 3 million barrels, according to sources.
