NEW YORK, Dec 31 (Reuters) - U.S. crude oil futures turned positive, rising back above $91 a barrel on Friday as a weaker dollar and technical support stopped a bout of year-end profit taking.
NYMEX crude oil for February delivery <CLG1> rose $1.49, or 1.66 percent, to $91.33 a barrel at 12:15 a.m. EST (1715 GMT). ICE Brent crude <LCOc1> rose $1.60 to $94.69 a barrel.
The U.S. dollar fell broadly as investors closed their books on 2010 but still managed to end a volatile year a bit firmer than where it began. [
]A weaker dollar typically lifts dollar-denominated oil prices as it lowers the value of dollars paid to producers and pulls down oil prices in markets using other currencies.
Technical support at $89 a barrel also helped oil price bounce back, traders said.
"The first signal for higher prices was the early firmness in crude spreads, in particular the February and March contracts. Even as flat prices were testing $89 this front spread had rallied," said Michael Korn, President of Skokie Energy in Princeton, New Jersey.
In early trade, oil tested Thursday's lows at $89.02 as long liquidation had overrun bullish economic data and a drawdown in crude inventories.
"This is a sudden reappraisal once the long liquidation was done. We've had this strange situation all morning of oil being lower even as equities and the euro were higher because of what looked like profit taking. I guess people got out of their positions now," said Peter Beutel, president, Cameron Hanover in Connecticut.
"Still, this is a very quiet day and trying to read too much into the market today would be a mistake," he added.
Crude oil was set to close the year up more than 12 percent due to a resurgence in global demand, an unusually cold winter for many heating oil consumers, and falling inventories.
Crude was on track to average $79.60 a barrel for the year, second only to 2008's record average of $99.75.
Analysts said they expected strong demand for raw materials, especially in China, to push oil even higher next year, although the global recovery remained fragile.
U.S. crude stocks fell last week for the fourth straight week, but the drawdown was less than expected and pressured prices.
The fall in gasoline stocks was much bigger than expected, supported by year-end holiday travel demand, possibly signaling rising consumption as the world's largest economy recovers from recession.
"The latest U.S. weekly data release show a continuation of the recent strength in oil demand," said analysts at Barclays Capital in a research note.
"December is set to be the strongest month of the year in demand terms, with particularly strong indications of gasoline demand," they added.
Including all products, the total US implied demand has risen to the highest level of the year and above the levels of 2008, said Olivier Jakob from Petromatrix.
It was, however, soaring demand in Asia that analysts said contributed most to healthy gains in oil and commodities in 2010. Prices in metals and soft commodities also beat records or climbed near multi-year highs.
The Reuters-Jefferies CRB index of 19 commodities is up 16 percent on the year, a more attractive return than on stocks.
OPEC SUPPLIES
Even with crude stocks slipping for four straight weeks and prices peaking at a 26-month high of $91.88 a barrel earlier this week, OPEC output has risen only slightly in December as Nigerian supply has increased, a Reuters survey found.
Core OPEC ministers have indicated they would not provide more oil supplies to arrest the oil rally, saying $100 crude was a fair price.
"With non-OPEC production growth expected to slow down to some 420,000 barrels per day next year, OPEC should face the welcomed opportunity to bring on stream substantial additional volumes," JBC Energy said. "This is particularly true for the second half of 2011, when we project the demand for OPEC crude to average clearly more than 30 million barrels per day," it added.
