LONDON, Oct 18 (Reuters) - Oil hovered near $81 a barrel on Monday, after earlier hitting its lowest in over a week, pressured by uncertainty over the U.S. economic outlook and as the battered dollar rallied.
Federal Reserve chief Ben Bernanke cemented expectations of more U.S. monetary easing on Friday but his comments lacked detail, raising doubts over the impact the measures will have on the economy of the world's largest fuel consumer.
U.S. crude for November <CLc1> fell 10 cents to $81.15 by 1059 GMT, after earlier hitting a session trough of $80.35, the lowest point since Oct. 8. December ICE Brent <LCOc1> fell 4 cents to $82.41.
Oil pared earlier losses after strikes at France's 12 refineries extended into a 7th day ahead of a nationwide march scheduled for Tuesday and the final Senate vote on President Nicolas Sarkozy's unpopular pension reform on Wednesday.
"I think that the only thing that is really supporting prices for now is the strike at Fos-Lavera that is removing product out of the market and supporting refinery activity elsewhere in Europe," said Christophe Barret, oil analyst at Credit Agricole.
Hundreds of French petrol stations have run out of fuel, forcing the government to dip into 30-day industry stocks. The head of the emergency policy division of the IEA said France can tap its strategic oil stocks without IEA approval if need be.
The U.S. dollar bounced from a 10-month low against a basket of currencies on Monday, as investors trimmed bearish bets against the greenback on some uncertainty as to how much easing the Federal Reserve will implement. <.DXY>
A stronger dollar makes commodities, like oil, more expensive for buyers using alternative currencies.
U.S. Federal Reserve Chairman Ben Bernanke on Friday offered his most explicit signal yet that the U.S. central bank was set to ease monetary policy further in a debt purchase programme described as a second round of quantitative easing, or QE2.
Oil pierced the upper end of a $70-$80 trading range this month that had held for much of the last year, on optimism a boost to the U.S. economy would improve weak fuel demand but the rally fizzled out at the end of last week.

"It looks like we are revising down the possible impact of QE2 and I think prices will return to the $70-$80 range in the coming days or weeks," Barret said.
The Fed next reviews policy on Nov. 2-3, when details about any stimulus moves and their implementation could emerge.
U.S. industrial output numbers will be carefully eyed later on Monday after data at the end of last week highlighted the fragile state of recovery in the world's largest economy.
