LONDON, Sept 25 (Reuters) - Oil remained above $106 a barrel on Thursday with a weakening dollar and growing signs of tightening supplies balancing concerns over slowing demand.
Falling demand in the United States, the world's largest energy consumer, and lingering uncertainty over a $700-billion bank bailout plan, will probably keep gains in check, analysts said.
U.S. light crude for November delivery <CLc1> rose 59 cents to $106.32 a barrel by 0744 GMT, after having fallen 88 cents to settle at $105.73 on Wednesday.
London Brent crude <LCOc1> gained 75 cents to $103.23.
"Oil is largely boosted by weakness in the U.S. dollar," said Mark Pervan, an analyst at Australia and New Zealand Bank in Melbourne. "The U.S. may be closer to reaching a deal to approving the bailout but there is still a lot of uncertainty on its overall impact on the economy."
The dollar slid against the euro and the yen on Thursday, hurt by lingering doubts over the U.S. government's proposed $700 billion bank rescue plan. [
]Oil has tumbled about 25 percent since hitting record highs of more than $147 a barrel in mid-July, dragged down by mounting evidence that high energy costs and economic woes were cutting global fuel consumption.
In a further sign of slackening demand, a U.S. government report showed nationwide oil demand over the past four weeks running 5.3 percent below last year in the midst of mounting economic turmoil in the country.
In Japan, the world's third-biggest oil consumer, crude oil imports also fell 3.3 percent to 4.13 million barrels per day in August from the same month last year, data from the Ministry of Finance showed on Thursday. [
]Still, analysts said slow recovery in oil and gas production in the U.S. Gulf of Mexico, falling inventories in the U.S. and lower OPEC supplies would continue to offer support for prices.
Mexico is temporarily cutting its crude oil output by 250,000 barrels per day because of damage to U.S. refineries from Hurricane Ike, state oil monopoly Pemex said on Wednesday. [
]U.S. refinery utilisation fell to the lowest level on record in the week through Sept. 19, U.S. government data show, reflecting shut-ins along the Gulf of Mexico caused by Hurricane Ike this month. [
]Crude stocks tumbled by 1.5 million barrels, less than analysts' expectations for a 2-million-barrel fall, while gasoline stocks fell for the ninth week to their lowest level since 1967.
In the Gulf of Mexico, home to a quarter of U.S. oil output, energy firms continued efforts to restart production at refineries and pipelines after Ike battered U.S. oil infrastructure in the biggest hit to the U.S. energy supplies since the 2005 hurricane season.
Hurricane Ike destroyed 52 offshore platforms in the Gulf of Mexico that produced a total of 13,300 barrels of crude oil and 90 million cubic feet of natural gas each day, the U.S. Mineral Management Service said on Wednesday. [
