LONDON, Oct 18 (Reuters) - Oil rose towards $82 a barrel on Monday, after earlier hitting its lowest in over a week, as strikes at French refineries made up for losses wrought by a rallying dollar and doubts over the U.S. economic outlook.
The week-old action, which has brought operations at France's 12 refineries to a near-standstill, lifted refined products futures and in turn sent crude oil prices up, offsetting the effects of a stronger dollar. [
]U.S. crude for November <CLc1> up 61 cents to $81.86 by 1402 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.
"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.
He was referring to a Mediterranean oil hub which has been blocked for 3 weeks by a protest against pension reform.
Oil defied a bounce in the U.S. dollar, which came back from a 10-month low against a basket of currencies on Monday as investors trimmed bearish bets against the greenback due to uncertainty over the extent and impact of further monetary easing. <.DXY>.
U.S. Federal Reserve Chairman Ben Bernanke on Friday gave his most explicit signal yet that the U.S. central bank was set to loosen monetary policy further in a debt purchase programme described as a second round of quantitative easing, or QE2, but he gave no details about the Fed's next step.
"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.
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.
The Fed next reviews policy on Nov. 2-3, when details about any stimulus moves and their implementation could emerge.
U.S. industrial production unexpectedly fell in September, while capacity utilization eased slightly, according to a report on Monday that supported expectations of further monetary easing next month. [
