SINGAPORE, Jan 28 (Reuters) - U.S. crude futures fell on Friday to a near two-month low on weak economic data and talk of OPEC raising output to cool prices, while a rosier outlook for Europe supported Brent.
Jobless claims rose in the U.S. overnight while the head of Kuwait Petroleum Corp said OPEC may need to boost output as high oil prices threaten the global economy.
Farouk al-Zanki, head of Kuwait Petroleum Corp, told Reuters at the World Economic Forum in Davos, Switzerland, he is concerned that current high oil prices may contribute to the start of another global downturn as they did in 2008. Kuwait is the fifth largest producer in OPEC.
Royal Dutch Shell's CEO Peter Voser has also voiced similar worries.
"The first signs are emerging that OPEC is responding, with a thinly veiled call for an emergency OPEC meeting by a Kuwaiti official and indications others are unilaterally raising output," JPMorgan analysts led by Lawrence Eagles said in its monthly oil report. The next OPEC meeting is scheduled for June.
U.S. crude oil for March delivery fell 23 cents to $85.41 a barrel at 0828 GMT and is on track to extend its decline for a second straight week.
ICE Brent crude for March rose 40 cents to $97.79 a barrel.
A rosier global economic outlook, especially in the euro zone, is driving Brent, said Ben Westmore, commodities economist at National Australia Bank.
He added that the OPEC price basket has not risen high enough to justify a change in production quotas.
However, "if this price trend continues, it's likely that OPEC will look at raising output within the next six to 12 months," Westmore said.
The divergent price movements for the two oil markers has pushed Brent's premium to West Texas Intermediate <CL-LCO1=R> to more than $12 a barrel on Friday, the highest since January 2009.
Near-record stocks in Cushing, Oklahoma, the delivery point for WTI contracts, have caused prompt-month spreads to collapse "and the market is now firmly in the supercontango zone," JPMorgan said in a Jan. 27 note.
In a contango market, the price of oil is progressively more expensive in future months than the front month.
More Canadian crude is expected to flow into Cushing in March through an extension of the Keystone pipeline even though additional storage capacity is being added, JPMorgan said.
"The risk of a really wide spread of $20-$30 to Gulf Coast crudes is not insignificant during the refinery maintenance season," the bank said.
Reuters markets analyst Wang Tao said technical charts showed that Brent's premium to WTI crude will rise to $15.30-$17.63 per barrel over the next four weeks.
However, some analysts were sceptical that the Brent-WTI premium would stay high given that spikes have collapsed previously.
"I do expect Tapis and Brent prices to be more in line with WTI" which is a better reflection of the fundamentally weak oil market than other benchmarks, Westmore said.
The first reading of U.S. economic growth in the fourth quarter will be released later on Friday.
U.S. economic growth likely accelerated in the fourth quarter of 2010, with consumer spending predicted to have increased at its fastest pace in three years.
The anticipated 3.5 percent annual growth rate would be the quickest since the first quarter of last year. (Reporting by Florence Tan; Editing by Michael Urquhart)
