NEW YORK, June 16 (Reuters) - Oil hit a record near $140 a barrel on Monday on weakness in the U.S. dollar and an emergency shutdown of a North Sea oil production platform that stirred supply worries.
The rally came despite expectations top world oil producer Saudi Arabia will soon boost output to its highest rate in decades amid calls from consumer countries like the United States for more output to ease an economic downturn.
"The week has started off with a bang, ... apparently on participants' lack of confidence in the Saudi's ability to stem rising prices," John Kilduff, senior vice president at MF Global wrote in a note.
U.S. light, sweet crude for July delivery <CLc1> was up $2.01 at $136.87 a barrel by 1630 GMT, off a record high of $139.89 set earlier in the session. London Brent crude <LCOc1> was up $1.54 at $136.55.
Prices leapt as the dollar fell versus the euro, snapping a three-day winning streak, amid expectations the European Central Bank will hike interest rates to fight inflation.
Commodities markets tend to have an inverse relationship with the dollar as it impacts the purchasing power of buyers using other currencies.
Dealers added that the shutdown of Norwegian oil producer StatoilHydro's Osenberg A oil platform in the North Sea due to a fire was also encouraging buying.
Earlier in the session, prices had dipped into negative territory after United Nations chief Ban Ki-moon said over the weekend that Saudi Arabia was set to increase output to 9.7 million barrels per day in July, its second supply boost in as many months. [
]That would be a rise of 550,000 bpd or over 6 percent since May and would take Saudi output to its highest monthly rate since August 1981, according to U.S. government data.
U.S. Energy Secretary Sam Bodman said Monday the United States, the world's largest energy consumer already hard-hit by soaring gasoline prices and a slumping housing market, would welcome the move. [
]Saudi Arabia's plans emerged ahead of a meeting of oil producers and consumers on June 22 to find a solution to record oil prices that have caused widespread consumer protests.
Some analysts said, however, the move may not be enough to stem oil's rally.
"The (Saudi) move does not seem to be enough to reverse the recent strength in prices, as it does little to repeal the longer-term expectations for tight demand-supply balances on the back of robust non-OECD demand and faltering non-OPEC supply," Barclays Capital said in a research note.
U.S. oil refiners said on Monday that they would not be interested in buying any additional Saudi oil unless the price was steeply discounted. [
]Oil has doubled in the last year and risen 40 percent since the start of this year, boosted by expectations that supply will struggle to meet demand from newly industrialising countries such as China and India.
Saudi Arabia is the only member of OPEC with the spare capacity to boost supplies quickly and significantly. It could pump around 2 million bpd more than it does.
The rapid price increase has spurred demands from politicians to introduce curbs on so-called speculators in the oil futures markets. (Reporting by Jane Merriman and Ikuko Kao in London and Jonathan Leff in Singapore; editing by Marguerita Choy)
