PERTH, Sept 29 (Reuters) - Oil extended its decline and fell towards $106 a barrel on Monday, pressured by gains in the U.S. dollar amid optimism that a vote on a $700 billion bailout to rescue the U.S. financial system is near.
Congressional leaders from both parties said they had reached a tentative agreement on Sunday, but questions abound as to whether the rescue plan, which would use taxpayer funds to buy up toxic mortgage debt, would restore confidence to shaky markets and head off a deep recession.
U.S. light crude for November delivery <CLc1> fell 50 cents to $106.39 a barrel by 0027 GMT, narrowing earlier losses of as much as 99 cents. The contract settled down $1.13 at $106.89 on Friday.
"Oil is down because of the U.S. dollar. I think the markets are also cautious about the bank bailout and there is some sense that the risky package could be bearish for oil demand," said Mark Pervan, a senior resource analyst at the Australia & New Zealand Bank (ANZ), based in Melbourne.
U.S. lawmakers were gearing up to vote on Monday on creating a $700 billion government fund to buy bad debt and to help ease the financial crisis, while two troubled European banks looked set for nationalisation. [
]The U.S. dollar rose against the euro and the yen on Monday, and hopes a bailout bill would soon be passed also spurred a rally in the U.S. stock index futures.
Oil prices have risen about 11 percent since the start of the year on geopolitical tensions in the Middle East, supply disruptions in Nigeria and a falling U.S. dollar. But they are down 28 percent from record highs above $147 a barrel struck in July as the economic crisis and high fuel costs hurt demand in the United States and other developed economies.
Further pressure has come as investors, who flocked into oil and other commodities earlier this year as a hedge against inflation and the weak dollar, shift into safer havens.
News that Iran, the world's fourth-largest exporter of oil, has avoided new sanctions in a United Nations vote over the weekend also kept prices in check.
The U.N Security Council unanimously passed a resolution on Saturday that again orders Iran to halt its nuclear enrichment work but imposes none of the new sanctions Washington and its allies wanted [
].But analysts said a slow recovery in oil and gas production in the U.S. Gulf of Mexico, home to a quarter of U.S. output, would offer some support for prices in the short term.
Some 57.4 percent of oil production and 52.8 percent of natural gas output in the Gulf of Mexico remained shut as of Sept. 25, the Minerals Management Service said on Friday. [
]Shell Oil <RDSa.L>, the largest producer in the Gulf of Mexico, expects the bulk of its offshore fields back on line within two weeks [
].Separately, the Organisation of the Petroleum Exporting Countries (OPEC) has no further plans to alter production levels as oil prices remain outside of control of fundamental factors like supply and demand, Venezuelan Oil Minister Rafael Ramirez said on Saturday [
