SINGAPORE, Oct 18 (Reuters) - Oil fell towards one-week lows on Monday as a rebound in the dollar prompted investors to halt their charge into commodities, while waiting for details about U.S. economic stimulus measures.
U.S. crude for November <CLc1> fell 47 cents to $80.78 by 0030 GMT, extending last week's drop of 1.7 percent. It touched $80.30 on Oct. 8, the lowest price since the beginning of the month, after reaching a five-month high of $84.43 a day earlier. December ICE Brent <LCOc1> fell 48 cents to $81.97.
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 program described as a second round of quantitative easing, or QE2, but gave no details on when, or how aggressively, it might act.
"QE2, which had been progressively bullish for oil over the course of September and into early October, ran out of steam as a driver for prices, at least for the time being, and probably until it is actually announced, along with details of its implementation," by November 3, when the next Fed meeting concludes, said Mike Wittner, Societe Generale's head of oil market research.
U.S. inflation unexpectedly slowed in September, despite a pick-up in retail sales, the government said. A survey showed the country's consumer sentiment unexpectedly dipped in early October to its weakest level since July. [
]Two top Federal Reserve officials over the weekend argued for further aggressive action by the central bank, with one saying the economy needs "much more" help and the other pointing to Japan's painful lessons. [
]The U.S. dollar rose from a more than eight-month low against the euro on Friday, extending gains against a basket of currencies on Monday by more than 0.2 percent, on bets recent declines were overdone, but a sustained rebound is unlikely given expectations for further U.S. monetary easing. [
]World stocks slid on Friday as concerns about a growing U.S. foreclosure crisis undermined the initial boost from Bernanke's speech indicating more monetary stimulus was on the way. [
]Asian stocks were seen likely to open mixed on Monday, as optimism over further policy support for the world's largest economy was offset by concerns over bank exposure to the U.S. mortgage market. [
]In France, President Nicolas Sarkozy is facing a make-or-break week for his unpopular pension reform as rail and refinery workers, truck drivers and street marchers ramp up pressure to scrap it before a crucial Senate vote.
