* Chinese rate rise could slow demand
* No OPEC action expected for now
* World economy can withstand $100 oil - Kuwait (Updates prices, adds delayed start of NYMEX floor trade in paragraph 3)

LONDON, Dec 27 (Reuters) - Oil fell on Monday, unravelling gains that took it to a 26-month high, after uncertainty about Chinese fuel demand following a surprise interest rate rise countered the impact of a blizzard in the U.S. Northeast.
U.S. crude for February <CLc1> traded down 55 cents at $90.96 a barrel by 9:44 a.m. EST (1444 GMT), after hitting an intraday peak of $91.88 -- the highest since October 2008. ICE Brent crude <LCOc1> eased 26 cents to $93.51 a barrel.
Floor trading on the New York Mercantile Exchange was delayed until 11 a.m. EST after a snowstorm snarled travel in the U.S. Northeast.
Oil prices have climbed 35 percent since this year's low in May, driven by the combination of a weakened U.S. dollar and then unusually cold weather in Europe and the United States that has boosted heating fuel demand and eroded inventories.
The rise in the price of oil and other commodities has raised concerns of inflation in major fuel-importing countries.
As it strives to prevent its economy overheating, China, the world's second-biggest oil burner after the United States, on Saturday raised interest rates for the second time in just over two months. [
] Markets had expected a rate rise, but the timing came as a surprise.When China last raised interest rates in mid-October, oil fell 4 percent, although the market soon recovered.
Analysts said this time the immediate impact was difficult to judge because trade is very thin over the year-end holiday period, but in general a slower Chinese economy implied reduced oil consumption.
"What it does show is that China is serious when it says 2011 is going to be the year of prudent fiscal policy," said Olivier Jakob of Petromatrix.
"Further Chinese interest rate hikes will now be expected for 2011."
WIDER COMMODITIES RALLY INTACT?
Longer-term and especially for other commodities with more fundamental strength than oil, analysts predicted a raw materials rally had further to run.
"This certainly doesn't spell the end of the commodities boom or the strong China story. It's a smart move that may have caught the market off guard," said Mark Pervan, senior commodities analyst at ANZ. [
]Commodities began to rise around September, coinciding with a wider financial markets rally, following U.S. quantitative easing that weakened the dollar.
A weaker dollar stokes buying in dollar-denominated commodities, made relatively cheap for holders of other currencies.

In December, the rally has also drawn strength from strong heating oil demand because of unusually cold weather in the northern hemisphere.
The first widespread blizzard of the season slammed into the northeastern United States, the world's top heating oil market, on Sunday. [
]Any real increase in demand and a subsequent drop in inventories could eventually persuade oil producers' group OPEC to act. But at a conference in Quito earlier in December, OPEC left existing output targets unchanged.
Ministers have said they would not increase output if a price rally were based on speculation rather than fundamentals of supply and demand.
Arab members of the Organization of the Petroleum Exporting Countries met at the weekend in Cairo when Kuwait's oil minister said the global economy could withstand an oil price of $100 a barrel.
Other exporters indicated OPEC might decide against increasing output throughout 2011 as the market was well supplied. [
]Regardless of OPEC output policy, production could rise from Iraq, which is excluded from OPEC's system of supply curbs as it recovers from war and sanctions.
Iraq's new Oil Minister Abdul Kareem Luaibi on Monday said the nation's production exceeded 2.6 million barrels per day for the first time in 20 years. [
