Crude Oil is trading today in the European session below the $81 level.
Crude prices edged lower on Wednesday as an unexpected increase in U.S. crude inventories raised concerns about demand.
According to data from the American Petroleum Institute released late Tuesday, U.S. crude stocks rose by 2.26 million barrels in the week ending June 14, contrary to analysts' expectations of a 2.2 million barrel draw.
Official U.S. inventory data from the Energy Information Administration is scheduled for release on Thursday, a day later than usual due to the U.S. holiday.
