Crude supplies had jumped more than analyst forecasts for the previous four weeks. The Energy Department's Energy Information Administration reports its weekly supply data later Wednesday. "If the Energy Department corroborates, this would be a bullish number," energy trader and consultant The Schork Group said in a report. Inventories of gasoline fell 3.6 million barrels last week while distillates also tumbled 3.6 million barrels, the API said. Analysts are worried Europe's debt crisis may force further government spending cuts that would hurt economic growth. Capital Economics expects Europe's economy to shrink 1 percent this year and 2.5 percent in 2013. "Large parts of the euro-zone are fundamentally uncompetitive and have unsustainable debt burdens," Capital Economics said in a report. "We still expect some form of euro-zone break-up to begin in the coming year or so." Investors will also be closely watching comments by the U.S. Federal Reserve about the strength of the recovery and monetary policy after its meeting Wednesday.
