Oil prices fall for fourth day after stockpile build

Crude oil prices fell for a fourth day on Wednesday, with jittery investors awaiting official U.S. stockpile figures later in the day after less comprehensive industry data showed a surprise build in inventories. The American Petroleum Institute (API) said crude stockpiles increased by 9.3 million barrels in the week to Oct. 28, more than nine times the amount expected by analysts polled by Reuters. U.S. West Texas Intermediate (WTI) crude was down 28 cents, or 0.6 percent, at $46.39 by 0014 GMT
