LONDON, Jan 27 (Reuters) - Brent crude oil pushed towards its biggest premium over U.S. crude in two years on Thursday as high inventories weighed on U.S. crude, while Brent remained supported by tight supplies and investors' momentum bets.
By 1016 GMT, the premium of Brent to U.S. crude was at $11.19, close to its highest since January 2009 after earlier touching $11.27.
U.S. benchmark crude oil for March delivery <CLc1> was down 96 cents to $86.37. ICE Brent for March <LCOc1> was down just 35 cents to $97.56 after rising 2.8 percent on Wednesday.
"The front month of U.S. crude is very weak due to high inventories at Cushing," said Christophe Barret, global oil analyst at Credit Agricole Corporate & Investment Bank.
According to the Energy Information Administration, stocks at the Cushing, Oklahoma terminal rose by 862,000 barrels week-on-week due to a fall in refinery utilisation and rising imports.
Cushing is the delivery point for the New York Mercantile Exchange's benchmark West Texas Intermediate (WTI) crude futures.
Overall U.S. crude inventories rose more than expected in the week to Jan. 21, up 4.84 million barrels compared with a forecast for 1.2 million in a Reuters analyst poll. [
]"The statistics published yesterday were globally relatively bearish. They showed strong increases in crude oil stocks on the U.S. Gulf Coast, and in the week before we saw a big increase too. It seems that high prices are now impacting demand," said Barret.
Investors also attributed the wide spread to a combination of high U.S. inventories and momentum chasing by traders.
"It's partly fundamentals-driven and partly market-driven, as the momentum chasers have been following Brent, but U.S. crude inventories are also more extended," said Gavyn Davies, chairman of Fulcrum Asset Management, a UK-based hedge fund manager.
JP Morgan analysts said in a note that Brent tightness reflected the ongoing decline in North Sea crude supplies and "the increased pull of Middle Eastern, Russian and West African crudes by Asia".
SUPERCONTAGOS
They added that pipeline flows would have to be reconfigured to ease high U.S. inventories, but the forward Brent-WTI spread indicated that the market does not see a solution by 2012.
"Prompt WTI spreads have to remain wide for some time to come, and supercontangos will remain a recurring feature on the landscape," they said.
An executive at Valero Energy Corp <VLO.N> said West Texas Intermediate had "almost become irrelevant" because of its deep discount. [

Brent was also supported by positive sentiment on the back of the U.S. Federal Reserve's commitment to maintain its economic stimulus package.
On Wednesday Fed policymakers voted unanimously to maintain a $600 billion bond-buying plan to fuel the economic recovery, boosting liquidity across the commodities complex and helping Asian equities to one-week highs [
]."In this sort of environment, you look for growth assets. As a result, equities and commodities are high up on the list," said Craig James, chief economist at CommSec in Sydney.
In addition, China's top 24 refineries are expected to process 170,000 barrels more crude oil per day this year than in 2010, or an increase of 4 percent, due to planned heavy maintenance, a Reuters survey found [
