LONDON, Oct 26 (Reuters) - Oil prices were broadly stable on Wednesday, moving in and out of negative territory after industry data showed U.S. crude stockpiles rose more than expected, though supply concerns and a weaker dollar gave support.
Brent crude futures for December were down 4 cents, or 0.04%, to $93.48 a barrel by 0849 GMT.
U.S. West Texas Intermediate (WTI) crude futures for December were up 25 cents, or 0.3%, to $85.57 a barrel.
But ongoing supply constraints, highlighted by the International Energy Agency's head warning of the "first truly global energy crisis", gave prices a floor.
Meanwhile Biden, facing criticism over high inflation, has warned that Saudi Arabia would face consequences for aligning with Russia and agreeing to reduce crude supply.
