PERTH, Oct 22 (Reuters) - Oil fell by more than $3 to near its lowest in 16 months on Wednesday, dropping back below $70 on mounting worries that output cuts by OPEC will not be enough to offset slackening energy demand in leading consumers.
An expected rise in weekly U.S. crude and fuel stocks in data due later in the day also weighed on oil prices, which tumbled along with other commodities including metals that were walloped by a rising U.S. dollar and renewed stock market selling.
U.S. crude for December delivery <CLc1> fell $2.58 to $69.67 by 0644 GMT, recovering from an earlier trough of $68.90 a barrel, near last week's low of $68.57, the weakest price since late June of 2007 and less than half of the record high in July.
London Brent crude <LCOc1> fell $2.28 to $67.44.
"People are just scared that the economy is going down the tube," said Tony Nunan, assistant manager of risk management at Mitsubishi Corp in Tokyo.
"There is a feeling that we are now going to see problems in the real economy; employment, real estate prices will continue to fall and the big concern now is how much economic growth is going suffer."
Asian stocks slumped to their lowest since December 2004 on Wednesday, with Japan's benchmark Nikkei average <
> down 6.8 percent, tracking losses in U.S. markets as poor U.S. corporate results fanned worries of a protracted slowdown. [ ]The price of oil has more than halved since hitting a record high above $147 in mid-July on worries that the financial crisis would slash energy demand in the United States, the world's largest energy consumer, and other industrial countries, prompting OPEC to scramble an emergency meeting this Friday.
OPEC Secretary General Abdullah al-Badri has led the call for output cuts, telling reporters on Tuesday that the world would face a huge oversupply of oil next year, if leading producers failed to cut supply. [
]More evidence of mounting global supplies is expected to emerge later in the day as U.S. crude oil stocks are expected to have risen by 2.6 million barrels last week, according to a Reuters poll of analysts. [
]A 100,000 increase in distillate stocks and a 2.8 million barrel build in gasoline inventories is also expected in the data due out at 10:35 a.m. EDT (1435 GMT), reinforcing fears that consumer fuel use is in decline.
U.S. weekly retail gasoline demand to Oct. 17 fell 6.4 percent year-on-year, Mastercard Advisors said Tuesday, though it rose compared with the previous week. [
]Though oil prices staged a strong rally earlier this week on expectations that OPEC would make significant cut to output, fears of a global recession have returned to haunt commodities.
The current U.S. economic downturn could be worse than the 1990-91 recession, with growth restrained for as long as one to three years, a top Federal Reserve policy-maker said on Tuesday. [
