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 possible U.S. economic stimulus measures.
U.S. crude for November <CLc1> fell 70 cents to $80.55 by 0603 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 56 cents to $81.89.
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," said Mike Wittner, Societe Generale's head of oil market research.
The Fed next reviews policy on Nov. 2-3, when details about any stimulus moves and their implementation could be revealed.
U.S. inflation unexpectedly slowed in September, despite a pickup in retail sales, the government said on Friday. A survey showed the country's consumer sentiment unexpectedly dipped in early October to its weakest level since July. [

]Key oil producer Saudi Arabia is holding a conference in Riyadh on Monday to mark the 50th anniversary of the Organization of the Petroleum Exporting Countries (OPEC), which the kingdom's oil minister Ali al-Naimi is scheduled to attend.
"Now we are entering growth because we went through a very, very bad recession. OPEC does not want to hinder that growth. We think $75-$85 will not hinder the growth of the economy," OPEC secretary general Abdullah al-Badri said on Friday, a day after the producer group met in Vienna and agreed to hold output steady.
"What really concerns us is the value of the dollar, because member-countries' income is being affected by this low level of the dollar," the secretary general said.
