LONDON, March 30 (Reuters) - Oil fell below $51 a barrel on Monday, extending the previous sessions' losses, pressured by a stronger U.S. dollar and a slump on global stock markets.
The U.S. government's rejection of turnaround plans for troubled automakers GM <GM.N> and Chrysler also dampened investor sentiment and encouraged selling.
U.S. oil for May delivery <CLc1> fell $1.85 to $50.53 a barrel by 0926 GMT. The contract fell $1.96 to settle at $52.38 a barrel on Friday, pulling back from Thursday's four-month high. London Brent crude <LCOc1> fell $1.58 to $50.40.
"Stock markets have taken a bit of a pounding, the dollar has improved and the U.S car industry news have all put a lot of pressure on oil markets this morning," said Rob Montefusco, a trader at Sucden Financial in London.
European stock markets followed Asian shares lower on Monday, while U.S. stock futures pointed downwards after the Obama administration's autos task force rejected turnaround plans for GM and Chrysler, raising the prospect of bankruptcies that could further hurt the ailing U.S. economy. [
]This renewed spirit of risk aversion strengthened the U.S. dollar, which rose against other major currencies on Monday, adding downward pressure on oil prices. [
]Oil has had a bullish first quarter of 2009, closing on Friday some 17 percent higher than the start of the year, thanks to rallying stock markets and tightening oil supplies as the Organization of the Petroleum Exporting Countries (OPEC) curbs exports.
However, the global economy remains weak, leaving analysts sceptical over the longevity of oil's rally.
Industrial output from Japan, the world's No. 3 energy consumer, fell by a greater-than-expected 9.4 percent in February, as weak demand weighed on an economy mired in its worst recession since World War Two, but factories forecast a small rise in production in coming months. [
]"The overall demand outlook, at least in the short term, continues to look quite bleak. The rally seen in the last two weeks might perhaps have run its course," said Toby Hassall, head of research at Commodities Warrants Australia.
Also casting a pall over oil prices were comments on Sunday from the Organisation for Economic Cooperation and Development (OECD) that unemployment rates were set to reach double digits in many developing and advanced countries. [
]Still, analysts said hopes that the U.S. economy had finally turned a corner were offering some underlying support for oil, keeping prices above the psychologically important $50-level.
President Barack Obama said in an interview published on Sunday that he saw "glimmers of stabilization" in some areas of the U.S. economy, including pockets of the domestic housing market. [
]Leaders of the Group of 20 developed and developing nations meet on April 2, hoping to restore global growth by the end of 2010, the Financial Times reported on Sunday, quoting a draft communique for a summit this week. [
]OPEC will be eyeing the G20 meeting, hoping it will agree measures to shore up the global economy and bolster oil demand.
