Oil investors are waiting for fresh information on U.S. stockpiles of crude and fuels when the Energy Department's Energy Information Administration releases its report — the market benchmark — later.
On Tuesday, a report from the American Petroleum Institute said that U.S. stocks of crude oil rose by a surprisingly large 5.1 million barrels last week, far above the increase of 1.4 million barrels expected by analysts surveyed by Platts, the energy information arm of McGraw-Hill Cos.
An annual 2.1 percent drop in March of crude oil imports by China also weighed on oil prices.
Brent crude, which sets the price of oil used by many U.S. refineries to make gasoline, was down 48 cents to $105.75 per barrel on the ICE Futures exchange in London.
