Investing.com - Oil slipped more, nearing $49 per barrel on Thursday, staying weak after a jump in U.S. stockpiles shown in industry data the day before.
U.S. crude was down 1.31% at $46.00 a barrel by 1110 GMT while Brent fell 0.6% to $49.41 a barrel.
Data on Tuesday from industry group the American Petroleum Institute showed U.S. crude stocks rose by 9.4 million barrels in the week to October 9 to 465.96 million, versus analyst forecasts for a 2.8 million barrels build.
The oil market has been volatile in recent months amid uncertainty about how quickly the global glut of crude is set to shrink.
Some analysts pointed to further weakness in the months ahead with a possible eventual interest rate rise in the U.S. pushing the dollar higher, which makes oil more expensive for holders of other currencies.
The U.S. Energy Information Administration was to release its weekly report on oil supplies at 11:00AM Eastern time.
