LONDON, Feb 9 (Reuters) - Oil ticked up above $40 a barrel on Monday as expectations of a giant U.S. economic stimulus package balanced signs of declining oil demand and a lower opening on European stock markets.
Tough talk from the Organization of Petroleum Exporting Countries (OPEC) that it would cut output again if needed at its March meeting, violence in Nigeria and renewed tensions between Iran and the West also lent some support.
U.S. crude for March delivery <CLc1> rose 23 cents to $40.40 a barrel by 1002 GMT. London Brent <LCOc1> climbed 22 cents to $46.43.
Christopher Bellew, broker at Bache Commodities in London, said both of the main oil futures contracts were trading within well established boundaries.
"The market is essentially range-bound," Bellew said.
European equities fell in early trade on Monday, with banks and oils leading losses as investors awaited the approval of Washington's massive stimulus plan and bank rescue package. [
]. Japanese stocks also fell [ ].Top aides to President Barack Obama on Sunday urged Democratic and Republican lawmakers to set aside political differences and quickly approve a massive economic stimulus package this week, as the world's largest economy suffers from the worst financial crisis in 70 years. [
]Later on Monday, the Democratic-led Senate, with the help of a handful of Republicans, was due to vote to end debate on the $827 billion plan to clear the way for its passage on Tuesday.
Oil prices fell on Friday after news of steep job cuts in the United States, where nearly 600,000 jobs were slashed last month, the most severe cut since December 1974 prompting worries of still weaker demand in the world's biggest oil consumer. [
]The financial malaise, which first sprang from home loan defaults in the United States, has swiftly spread to Europe and Asia, pushing a string of industrialised nations into recession.
The economic slowdown has depressed energy demand around the world, causing prices to plummet more than $100 from a peak of near $150 struck last July.
OPEC will take whatever action is necessary to balance the oil market when it next meets on March 15, the group's president said in a statement on Friday. [
]OPEC sources have indicated the group could cut a further 1 million bpd from output when it next meets, adding to the 4.2 million bpd in cuts announced since September.
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. [
]On the geopolitical front, Western powers said on Saturday Iran risked isolation and more sanctions if it did not comply with demands to rein in its nuclear programme, but Washington also reaffirmed its offer for talk with Tehran. [
