SINGAPORE, March 8 (Reuters) - Brent crude fell below $115 on Tuesday on reports Libyan leader Muammar Gadaffi was looking for a way to step down and end the fighting that has slashed the nation's exports, and investors were also soothed by OPEC assurances of supply to the market.
As much as 1 million barrels of Libyan output has been disrupted by clashes between Gaddafi and rebels, or about two-thirds of normal production. That is just above 1 percent of global daily consumption.
Two Arab newspapers and al Jazeera television said on Monday Gaddafi was looking for an agreement allowing him to step down, but there was no official confirmation of the reports.
"I'm not surprised that Brent is running a little bit out of steam," said Matthew Lewis, an analyst at CMC Markets in Sydney.
"In terms of the Libyan crisis, there is a lot of speculation that perhaps Gaddafi is looking to extradite himself. That may put an end to the crisis and the oil price would fall fairly rapidly."
Algerian Oil and Energy Minister Youcef Yousfi told Reuters that the market remained well supplied despite the cut in Libyan exports and that OPEC members had no plans to meet for now.
"I think it is more psychological effect than physical deficit of oil in the market," he said. "I don't think really there is a deficit."
ICE Brent crude for April shed 35 cents to $114.69 a barrel at 0303 GMT, after hitting $119.79 on Feb. 24, the highest prices since 2008. U.S. crude on Tuesday slid 61 cents from a 2-1/2-year peak to $104.83.
U.S. crude closed above $105 on Monday, its highest since September 2008, buoyed by traders who sold Brent and bought West Texas Intermediate, unwinding a popular trade that had blown out to a record $17 a barrel last week.
The Brent/WTI <CL-LCO1=R> spread has shrunk by more than $7 since then, ending Monday at its narrowest since January.
Concern has prevailed that violence and supply disruptions may spread to other countries in the region.
But so far oil is flowing as usual from the world's biggest producers in the Mideast Gulf. Saudi Arabia, the world's top exporter and home to most of OPEC's spare capacity, has increased production to at about 9 million barrels per day.
OPEC ministers are holding informal consultations about oil prices and the Libyan crisis, but the group is not planning to hold an emergency meeting, an OPEC delegate said on Monday.
If crude oil prices stay high for an extended time, analysts said, Asian countries from China to India might not be able to sustain the growth pace that has driven the global economy.
Major U.S. oil companies have halted trade with Libya and big banks have started to pull back from funding such deals because of U.S. sanctions, in moves that will further disrupt oil flows from the torn country.
Major Libyan oil ports Ras Lanuf and Brega in the east of the country are closed as violence in the area has hampered operations at the terminals, shipping sources said on Monday.
But a coordinated release of strategic oil stocks by OECD economies is not yet needed because the oil supply disruption caused by an uprising in Libya remains limited on a global scale, the International Energy Agency (IEA) said on Monday.
The White House said on Monday the price of oil was one factor -- but not the only factor -- that would be used when determining whether the United States will tap its strategic oil reserve.
U.S. crude oil stockpiles could have risen modestly last week as imports likely rose, a preliminary Reuters poll ahead of weekly inventory reports showed on Monday.
On average, crude inventories added 300,000 barrels in the week to March 4, after a surprise drawdown the week before, the poll of nine analysts showed.
Gasoline stocks were forecast down 1.3 million barrels, on average, as demand improved and imports likely fell, the analysts said.
Distillate stocks, which include heating oil and diesel fuel, likely dipped 1.3 million barrels, on average, with demand likely higher on late winter cold.
The industry group American Petroleum Institute will issue its weekly inventory report on Tuesday, at 2130 GMT, followed by government statistics from the U.S. Energy Information Administration on Wednesday, at 1530 GMT. (Editing by Ed Lane)
