SINGAPORE, June 9 (Reuters) - U.S. oil prices fell more than $1 to below $138 in early trade on Monday after rocketing nearly $11 higher to a record high last Friday, their biggest ever one-day gain, on the falling dollar and Middle East jitters.
U.S. light, sweet crude for July delivery <CLc1> fell as much as $1.42, or over 1 percent, to $137.12 a barrel in opening trade on the Global electronic platform. By 2223 GMT, it was trading at $137.79, down 75 cents.
The contract surged $10.75 or 8.4 percent on Friday, hitting a new record of $139.12 a barrel as the slumping dollar and mounting tension between Israel and Iran fuelled a buying frenzy.
A forecast by investment bank Morgan Stanley that oil prices could top $150 a barrel by the July 4 U.S. holiday added to Friday's speculative ferver, taking two-day gains to more than $16 a barrel and reversing two weeks of losses.
Oil's six-year-long rally has gathered pace this year, with prices rising more than 40 percent since January as funds hedge against the dollar and some bet that long-term oil supplies will struggle to keep up with demand in the decades ahead.
At the weekend key OPEC officials maintained they saw no need to consider pumping more oil now, despite the surge.
"I think there is enough oil in the market, I did not hear anybody calling for a meeting," Shokri Ghanem, head of Libya's National Oil Corporation and the country's top oil official, told Reuters in an interview. [
]OPEC, supplier of more than a third of the world's oil, is next scheduled to meet on Sept. 9 to discuss oil policy.
Saudi Oil Minister Ali al-Naimi and his Pakistani counterpart agreed in a meeting on Sunday that oil's surge was not linked to fundamentals, the Saudi Press Agency reported. [
]While consumer nations have often urged the cartel to tame prices by pumping more crude, Group of Eight energy ministers meeting in Japan at the weekend urged domestic efficiency and technology as the long-term solution to record oil, refraining from a call to pump more crude now. [
]Oil's latest boom has heightened the risk to economic growth in major consumer countries including the United States, whose economy already is hobbled by a housing crisis.
U.S. oil demand is also in decline as high prices bite, but many traders have focused instead on the falling greenback, which extended losses on Friday on data showing the U.S. economy lost jobs for the fifth straight month and the unemployment rate shot up to its highest in more than three years. [
]The AAA travel group on Sunday said U.S. average prices for regular gasoline topped $4 for the first time. [
]Further support last Friday came from remarks by Israel's transport minister that an attack on Iran's nuclear sites looked "unavoidable." It was the most explicit threat yet against Tehran from Prime Minister Ehud Olmert's government. [
]Some warned of worse to come.
"I think it will go higher," said Ghanem, who is also head of Libya's OPEC delegation. "The easy, cheap oil is over, peak oil is looming." (Reporting by Jonathan Leff; Editing by Bernard Woodall)
