(Adds OPEC comment, hedge fund manager comment, updates prices)
By Jane Merriman
LONDON, Jan 31 (Reuters) - Oil fell more than one percent on Thursday, pressured by concerns over troubles in financial markets despite another cut in U.S. interest rates, while rising fuel inventories in the top energy consumer also weighed.
U.S. light crude for March delivery <CLc1> dropped $1.06 to $91.27 a barrel by 1250 GMT, more than reversing a gain of 69 cents on Wednesday.
London Brent crude <LCOc1> lost 86 cents a barrel to $91.67.
European stock markets [
] were down on Thursday despite the hefty 50 basis point cut in interest rates from the U.S. Federal Reserve to try to avert an economic slowdown.Gold, a traditional safe haven for investors, was firmer, boosted by the U.S. rate cut and a weak dollar.
"The likelihood of OPEC adding any additional barrels to the market are rapidly diminishing amidst all the economic gloom from the U.S.," said Rob Laughlin, analyst at broker MF Global.
Iran Oil Minister Gholamhossein Nozari said on Thursday oil markets were well supplied and he saw no need for the Organization of the Petroleum Exporting Countries to boost production when it meets in Vienna on Friday. [
]The prospect of a cut in OPEC output levels at some stage has even been raised.
"With the lower seasonal crude oil requirement, then perhaps we should take off the market what we have been recently increasing," a delegate from one of OPEC's bigger producers said.
U.S. SLOWDOWN
The prospect of a downturn in the U.S. economy alongside seasonal supply/demand factors has contributed to a decline in speculative flows into oil.
"There will be a seasonal stock build in the coming weeks and the long-awaited exit of speculative fund capital seems to have begun," said Markus Mezger, a partner at hedge fund Tiberius Asset Management.
"We are not too optimistic that prices above $80 a barrel could be sustained in 2008."
U.S. Department of Energy inventory data published on Wednesday showed higher-than-expected builds in crude and gasoline stocks.
The Energy Information Administration said U.S. crude stocks rose by a bigger-than-expected 3.6 million barrels last week, while gasoline stocks rose by 3.6 million barrels, also more than expected. [
]The Fed's latest rate cut has brought U.S. rates to their lowest since June 2005. But it was overshadowed by speculation of more credit rating downgrades of U.S. bond insurers, which could bring further pain for the banking sector, already nursing big losses from bad housing-related loans.
Oil has been supported by positive supply/demand fundamentals and reached a record of $100.09 a barrel on Jan. 3, buoyed partly by expectations of long-term supply constraints.
But prices have fallen back since then, largely due to fears of a U.S. slowdown and the its impact on demand.
"The Department of Energy data continues to point to comfortable flows that fail to confirm the market's larger bullish hypothesis," said Tim Evans, oil analyst at Citi. (Additional reporting by Felicia Loo in Singapore; editing by James Jukwey)
