“There has been widespread liquidation across the grains, metals and oil markets ahead of the German Bundestag lower house of parliament vote on Thursday on whether to back new powers for the euro zone’s rescue fund,” said Phillip Streible, analyst at MF Global in Chicago.

Brent futures fell $2.96 to $104.18 by 2:18 p.m. EDT (1818 GMT). US crude dropped $3.24 to settle at $81.21, wiping out much of Tuesday’s gains.

Weekly data from the United States’s Energy Information Administration (EIA) showed a 1.9 million barrel increase in crude oil inventories, higher than the 800,000 rise expected by a poll of analysts.

Wall Street fell ahead of an audit of Greece’s finances to decide whether the nation gets more aid to avoid bankruptcy.

Eyes are on Germany to see if it will agree to a bailout.
