SINGAPORE, April 15 (Reuters) - Oil futures advanced to all-time peaks on Tuesday, supported by supply disruptions and speculation that the dollar may continue to trend lower.
U.S. light crude for May delivery <CLc1> rose 39 cents to $112.15 a barrel at 0634 GMT, after touching $112.48 a barrel, the highest level ever reached by U.S. crude futures.
U.S. futures are up 17 percent from the start of the year.
London Brent crude <LCOc1> rose 36 cents to $110.20 a barrel, after a record-high of $110.45 earlier in the session.
"It has some self-fulfilling momentum at the moment," said David Moore, commodities strategist at Commonwealth Bank of Australia.
"But there are no specific new fundamental factors that should drive it higher from yesterday."
Tetsu Emori, fund manager at Astmax Co Ltd said prices had risen due to automatically placed buying orders once the previous record had been breached. Emori sees the next resistance target at $115.00 a barrel.
Rising global crude oil demand, such as from rapidly growing China, has put oil in tight supply and driven its rally. The advance has been helped by a low dollar and investment flows from hedge and pension funds into commodities and oil.
But that is balanced against increasing worries that an economic slowdown that mean a sharp drop in U.S. and world demand for commodities.
Underlining supply fears, Mexico -- one of the top exporters to the U.S. market -- kept its three main crude oil exporting ports in the Gulf of Mexico shut on Monday due to bad weather. [
]Those three ports ship about 80 percent of Mexico's crude exports. A smaller port in the Pacific was also shut, the Mexican government said.
"The system is so tight that any supply problems cause real concern," said Robert Nunan of Mitsubishi Corp in Tokyo.
"We just don't have the big cushion any more that we used to have, so it's much easier for money to come in and prop up prices now," he added.
PIPELINE UP AGAIN
Easing some supply concern, oil major Royal Dutch Shell Plc <RDSa.L> restarted the giant U.S. Gulf to Midwest Capline crude oil pipeline on Monday after completing repairs on a small leak discovered on Friday, the company said. [
]Shell had shut the 1.14 million barrels per day (bpd) capacity line on Friday after a worker discovered a crack that resulted in approximately 10 gallons of oil being spilled.
On Tuesday, the dollar edged up against the yen and the euro in cautious trading ahead of U.S. economic data and first-quarter earnings results from financial institutions, which are expected to give clues on the state of the economy and credit markets.
But it was still below highs reached after the Group of Seven financial heads made its strongest expression in seven years about the volatility in major currencies and some dealers said the weak dollar trend would continue.
A weak dollar tends to raise prices for commodities denominated in that currency by boosting non-U.S. spending power and by attracting investors seeking an inflation hedge.
U.S. gasoline futures hitting fresh highs on Monday also helped prices.
They rose as the United States gears up for the summer driving season, when demand traditionally peaks, but the Energy Information Administration has said drivers may use less for the first time since 1991, due to lofty pump prices and a weak economy.
And the U.S. government said U.S. consumers were spending more than ever to fill up at the pump, as the average price for gasoline climbed to a new high of $3.39 a gallon after rising 5.7 cents over the last week. [
]U.S. crude oil inventories figures are due on Wednesday.
They likely rebounded last week after a surprise drawdown the week before, with an increase in imports lifting supply, according to a preliminary Reuters poll of eight industry analysts. [
