Crude prices dropped on Wednesday, with Brent reatriting below $70 a barrel and U.S. West Texas Intermediate sliding below $65, dragged down by a sharp rise in U.S. crude supplies.
May Brent crude slipped 0.6 percent to $69.69 a barrel. U.S. WTI crude futures dipped 0.8 percent to $64.72 a barrel.
The falls came after fresh figures from the American Petroleum Institute (API), which showed an unexpected 5.3 million barrels increase in crude stocks in the week to March 23, to 430.6 million barrels.
