NEW YORK, Dec 6 (Reuters) - U.S. oil prices eased from a 26-month high near $90 a barrel on Monday as the dollar strengthened and countered support from higher demand caused by cold weather in Europe and parts of the United States.
The euro fell sharply against the dollar, its first decline in four sessions, on renewed fears the euro zone's debt problems could spread. The dollar index <.DXY> against a basket of currencies also strengthened. [
]Cold weather in Europe and the United States and expectations that economic recovery will accelerate and push crude higher in 2012 demand picks up helped push oil to a two-year peak earlier on Monday.
U.S. crude for January delivery <CLc1> fell 24 cents to $88.95 a barrel at 12:42 p.m. EST (1742 GMT), having eased from an earlier peak at $89.76, the highest intraday front-month price since Oct. 9, 2008.
Total U.S. crude trading volume was above 456,000 after midday Monday in New York, 25 percent below the 30-day average.
ICE Brent crude for <LCOc1> fell 22 cents to $91.20 a barrel.
"We've had a bit of a pullback -- $90 is being a sticking point for (U.S. crude) at the moment and we had a little dip because of the euro," said Rob Montefusco, a trader at Sucden Financial.
Euro selling after its rebound last week was helped along by news that IMF chief Dominique Strauss-Kahn will present a report, a copy of which was obtained by Reuters, to euro zone finance ministers meeting in Brussels, saying more action is needed from member states. [
]The dollar's strength and worries about the euro zone economies limited the support for oil from U.S. Federal Reserve Chairman Ben Bernanke's remarks on CBS-TV's "60 minutes" saying it is possible U.S. monetary policymakers might increase the $600 billion in asset purchases announced at the last Fed meeting.

]COLD SNAPS, BACKWARDATION EYED
The U.S. Northeast, top U.S. heating oil consuming region, will average near to below normal temperatures over the next six to 10 days and below normal temperatures were expected in Northeast and Northwest Europe, according to DTN Meteorlogix, a private forecaster. [
] [ ]U.S. heating demand was expected to be 16.3 percent above normal for the week to Dec. 11, according to the U.S. National Weather Service. Heating oil demand was forecast at 16.1 percent above normal for the same period. [
]The wintry weather has allowed Brent crude to move into backwardation -- where the front-month price is more than next month's contract <LCO-1=R> <0#LCO:> -- and many analysts expect the trend to strengthen. [
]Forward futures contracts for U.S. light crude <CLc1> <0#CL:> moved into backwardation from mid-2011, although very prompt contracts stayed at small discounts.
A smaller discount or a price premium for front-month crude versus the near-month, could make it less profitable to store crude and help bring down what are perceived to be bulging stockpiles of crude oil.
U.S. crude inventories were at nearly 360 million barrels in the week to Nov. 26, according to the government, 19.8 million barrels above the year-ago period. [
]"This backwardation, which was rarely evident in the past few years, is likely to bring more buyers into the arena," analysts at Commerzbank said in a report.
At least five banks raised their mid- or long-term price forecasts last week, citing factors such as rising demand in emerging markets, faster global economic growth and OPEC's reluctance to boost output. [
]For example, J.P. Morgan said on Friday oil would top $100 in the first half of 2011 and $120 before the end of 2012, predicting OPEC would be very slow to react to higher prices.
The Organization of the Petroleum Exporting Countries meets on Dec. 11. Rather than raise output to curb prices, OPEC is likely to roll over existing policy, ministers have said. (Additional reporting by Alex Lawler in London and Jennifer Tan in Singapore; Editing by Marguerita Choy)
