NEW YORK, Feb 9 (Reuters) - Oil prices rose slighty on Monday after the Organization of Petroleum Exporting Countries said it was willing to cut oil output further if needed to counter slumping demand.
The market also drew support from optimism that the administration of U.S. President Barack Obama would secure Congressional passage this week for a giant U.S. economic stimulus plan.
U.S. crude for March delivery <CLc1> rose 43 cents to $40.60 a barrel by 12:45 p.m. (1745 GMT). London Brent <LCOc1> climbed 54 cents to $46.75.
"The stimulus and OPEC talking tough, signs from Saudi Arabia that they're going to cut production-- these are all things that are adding to the bottom line right now," said Phil Flynn, an analyst at Alaron Trading in Chicago.
Secretary-General Abdullah al-Badri reiterated OPEC's willingness to cut oil production further to steady prices at the group's next supply policy meeting on March 15 in Vienna.
"If we think we still need more action, I'm sure the conference will take more action to stabilize the market," he said.
Badri also said the 12-member group appeared to be implementing promises of production cuts more thoroughly than expected by some, with 80 percent compliance.
OPEC has said it will cut oil supply by 4.2 million barrels per day (bpd) from September's level in an attempt to bolster oil prices that have fallen from a record high of almost $150 a barrel last July.
STIMULUS
Top aides to President Obama on Sunday urged Democratic and Republican lawmakers to set aside political differences and quickly approve the stimulus package this week, as the world's largest economy suffers from the worst financial crisis in 70 years. [
]"Basically the market knows that the stimulus package is coming in one form or another, and last week when President Obama spoke about it, we got a nice little rally, but it's going to be more difficult to rally on that every day."
The Democratic-led Senate, with the help of a handful of Republicans, was due to vote to end debate on the $827 billion plan on Monday to clear the way for passage on Tuesday.
Crude prices were also lifted by a weaker dollar, which slid on Monday as investors anticipated a financial rescue package.[
]Renewed violence in Nigeria also helped buoy oil prices. Nigerian militants attacked a gas plant operated by Royal Dutch Shell <RDSa.L> in the Niger Delta on Saturday and warned of more attacks to come, but the army said it had repelled the raid and killed three gunmen. [
]Despite Monday's gains, oil prices were limited by worries that demand could weaken further in the U.S., the world's biggest oil consumer.[
]Oil prices have tumbled from a record high above $147 per barrel in July as the global economic downturn slashed demand for fuel.
