LONDON, March 2 (Reuters) - Oil prices fell below $44 per barrel on Monday on worries the deteriorating state of the world economy would further damage oil consumption.
The U.S. government threw a new $30 billion lifeline to American International Group <AIG.N> on Sunday as the insurer prepared to report the biggest quarterly loss in corporate history. AIG is expected later on Monday to report a fourth-quarter loss of about $60 billion. [
]In London, HSBC <HSBA.L> launched a $17.75 billion rights issue -- Britain's largest ever -- to shore up its balance sheet after profits fell and bad debts soared in the United States.
Stocks fell sharply in Europe and Asia. [
] [ ]Comments from Iran, the second-biggest producer in the Organization of the Petroleum Exporting Countries, that the producer group was unlikely to cut production again at a meeting this month, added further downward pressure on prices.
U.S. crude <CLc1> fell $1.65 to $43.11 by 0900 GMT. The contract snapped a three-day rally on Friday to settle down 46 cents at $44.76.
London Brent crude <LCOc1> fell $1.55 to $44.80 a barrel.
"Economic pessimism and weak equities are dragging us lower today," said Christopher Bellew, oil broker at Bache Commodities in London. "The AIG bailout and HSBC rights issue are again focusing attention on the fragility of the financial system."
CONFLICTING OPEC SIGNALS
Oil is being undermined by persistent worries about the U.S. economy. Data on Friday showed it shrank by 6.2 percent in the fourth quarter from a year ago, the deepest slide since 1982. [
]Conflicting signals from some OPEC members on whether the group would reduce output at its March 15 meeting encouraged the sell-off.
Algerian Energy and Mines Minister Chakib Khelil said it was quite possible that OPEC would cut oil output at its next meeting scheduled for March 15. [
]But Iran's oil minister, Gholamhossein Nozari, said he did not expect OPEC to slash output again because an 80 percent commitment by the group to recent curbs had helped stem price falls, media reported on Sunday. [
]Oil prices have plunged by more than $100 a barrel since a peak of nearly $150 last July as demand has tumbled. To shore up prices, OPEC has pledged to cut output by a total of 4.2 million barrels per day (bpd) since September.
The U.S. Department of Energy said on Friday it hoped OPEC would consider the "global economic situation" when it reviewed its output policy in Vienna.
In a sign that investors were becoming more bearish, there were more open interest positions at the $25 and $30 put options on the NYMEX April crude oil contract compared with the previous week, Reuters data showed on Friday. [
]And crude oil investors on the New York Mercantile Exchange cut net long positions in the week to Feb. 24, according to data from the U.S. Commodity Futures Trading Commission. [
]The market was awaiting key data on Monday, including U.S. personal income and consumption and construction spending for January as well as the U.S. February ISM manufacturing index. (Reporting by Christopher Johnson; editing by Anthony Barker)
