LONDON, Dec 2 (Reuters) - Oil prices inched down on Thursday following an increase in new U.S. claims for unemployment benefits and after the ECB kept its interest rate unchanged, and made no commitments to ramp-up its bond purchasing programme.
Front-month U.S. crude oil prices <CLc1> fell by 20 cents to $86.55 a barrel by 1431 GMT, still within sight of three-week highs of $87. ICE Brent <LCOc1> futures rose 15 cents to $89.02.
Despite the increase in new weekly unemployment benefit claims, a drop in the underlying trend suggested an improvement. [
]This is in line with data on Wednesday showing private employers added 93,000 new staff in November, the biggest rise in three years.
Friday's comprehensive non-farm payrolls data is expected to show a rise in overall nonfarm payrolls of 140,000 last month, based on a Reuters poll of analysts. [
]In Europe, the ECB kept its key interest rate at record lows of one percent and pledged to extend its liquidity safety net for banks at least until April next year on continued fears about the health of some euro zone members.
The central bank said its bond purchasing programme was ongoing, but made no commitment to increase the pace despite expectations of further measures to fight the debt crisis. [
]Up until mid-November, the ECB was expected to withdraw its bank crisis support mechanism by switching to competitive auctions, but renewed contagion fears after Ireland's bailout scuppered plans.
The euro slipped versus the dollar, erasing earlier gains, after expectations of an increase of bond purchases went unfulfilled.
"Oil prices are lower because of the stronger U.S. dollar related to Trichet's comments. Some markets expected he would say something about increased bond purchases, and that has not happened, at least in the way market participants had expected," Commerzbank analyst Carsten Fritsch said.
"Apart from that, prices are still showing remarkable signs of strength," Fritsch said, noting that the cold spell in Europe was supporting Brent prices, widening the differential between WTI and Brent. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Prices dipped earlier in the session after a Chinese central bank adviser said that the country's monetary policy will tighten steadily next year to counter inflation and excessive global liquidity. [
]"While we are still wary about going long a number of commodity complexes at these levels, the markets clearly feel otherwise, buoyed by the positive macro data that has been streaming out over the last two days," MF GLobal analyst Edward Meir said, referring to Wednesday's positive job data from the United States.
PRICE OUTLOOK
U.S. crude oil prices are currently less than $2 away from a 25-month peak of $88.63 reached on Nov. 11, while Brent prices are shy of the $89 a barrel mark.
"We seem to be close to the top of the trading range, so we will need something to push it through $90 and cold weather may not be enough," Christopher Bellew from Bache Commodities said.
Investment bank Goldman Sachs said U.S. crude prices are likely to average $100 a barrel in 2011 and $110 a barrel in 2012 on the back of a "new structural bull market". [
]"We expect in 2011 and 2012 that the transition from a cyclical recovery to a new structural bull market will lead to new record annual average prices above the 2008 high of just under of $100 a barrel," Goldman said in a Dec. 1 report.
On Wednesday, U.S. crude oil inventories data from the Energy Information Administration showed weekly a surprise gain of 1.1 million barrels. [
]"The latest data from the U.S. showed that oil inventories actually rose amid weakening consumption. This could pose a risk for prices and limit the upside potential in the coming days, despite the general improvement in market sentiment," Singapore-based Credit Suisse analyst Stefan Graber said.
U.S. gasoline stockpiles rose in line with forecasts last week; while a weekly 937,000 barrel drop in East Coast gasoline stocks lifted gasoline futures to an almost seven-month high on Wednesday.
