NEW YORK, Oct 21 (Reuters) - Oil tumbled 4 percent on Tuesday amid worries a global recession will crush fuel demand, limiting the impact of any supply cuts by OPEC.
U.S. crude for November delivery <CLc1>, which expired on Tuesday, settled down $3.36 at $70.89 a barrel.
London Brent crude <LCOc1> traded down $2.33 at $69.70 at 2:38 p.m. EDT (1838 EDT).
The slide came as U.S. stocks fell on concern that earnings could be driven down by slower consumer demand. [
]"Crude prices are down on demand consideration, with weakness being stoked by bearish economic data," said Kyle Cooper, director of research at IAF Advisors.
U.S. weekly retail gasoline demand to Oct. 17 fell 6.4 percent year-on-year, Mastercard Advisors said Tuesday, though gains were seen on the previous week. [
]Total Asian demand for West African crude was down 27 percent to 918,000 barrels per day (bpd) in November from 1.25 million bpd in October as demand from India, Indonesia and Taiwan decreased, according to traders. [
]The oil market has slid 50 percent since hitting a record high above $147 in mid-July. The fall came as demand slumped in the United States, the world's largest energy consumer, and other industrial countries hit by the credit crisis.
The Organization of the Petroleum Exporting Countries is due to meet in Vienna on Friday. The producer group is expected to reduce output to defend prices and temper the effects of the financial crisis.
Iran has said a drop in demand could push OPEC to cut output by 2 million to 2.5 million barrels per day (bpd), while other members have said a smaller cut may be needed.
OPEC could face an intense debate on how much oil members should take off global markets as they balance their price needs against risks to a fragile world economy. [
]OPEC Secretary General Abdullah al-Badri has led the call for output cuts, telling reporters Tuesday that the world faces an over-supply of oil next year if leading producers fail to cut supply. [
]"If things stay as they are, there will be a huge excess of supply in 2009," Badri said.
The International Energy Agency, which advises industrialized countries, has said an OPEC output cut could prolong a global economic slowdown.
