U.S. crude oil futures fell on Wednesday ahead of a government inventory report expected to show crude supplies rose last week and amid gloomy economic data that pressured equities. A report of accelerating U.S. private sector job losses that helped push Wall Street lower at the open and a Reuters survey showing OPEC output fell in March but remained above an agreed-upon target also provided pressure on oil. "Crude and products futures slumped overnight on light volume as traders brace themselves for possible news for a large build in crude stockpiles and world equity markets retreat before the G20 leaders meet today in London," Addison Armstrong, analyst at Tradition Energy, said in a note. The U.S. Energy Information Administration will release its inventory report Wednesday at 10:30 a.m. EDT (1430 GMT). The American Petroleum Institute on Tuesday said that in the week to March 27, crude supplies rose 3.3 million barrels to 357.8 million barrels. Gasoline stocks fell 451,000 barrels and distillate stocks rose 1.8 million barrels. [API/S] A Reuters analyst survey yielded a forecast for crude stocks to have risen 2.5 million barrels last week while gasoline stocks fell 1.4 million barrels and distillate supplies declined 800,000 barrels.
