Oil falls below $80 a barrel

Oil has fallen nearly 1 percent to below US$80 a barrel, as doubts about a recovery in oil demand outweighed positive economic signals.

US crude for December lost 78 cents to settle at US$79.62. London Brent crude fell 90 cents to settle at US$77.99

"Economic indicators continue to show an economy on the mend, but we are not seeing any real signs of that in energy demand," said Peter Beutel, president at Cameron Hanover in New Canaan, Connecticut.

The number of US workers filing new claims for jobless insurance fell more than expected last week to a 10-month low, the Labor Department said, with continuing claims dropping to the lowest since March.

US non-farm productivity in the third quarter rose at its fastest pace in six years, government data showed on Thursday.

Oil markets have been looking to equities and wider macroeconomic data in recent months for signs the economic crisis is easing and energy demand may rebound.

These external factors have been largely responsible for this year's price rally, which has seen prices nearly double since lows near US$40 a barrel in January.

But rallying US equity prices on Thursday had a limited impact on oil as the market instead focused on ballooning product stocks.

US distillate stocks - often taken as a more faithful snapshot of demand than crude oil - fell 400,000 barrels compared to analyst expectations for a 1 million-barrel decline. They remain near 26-year highs and analysts said this will cap price rises in the event of a cold winter.

"The economy is still muddled. While the EIA data had crude supply lower, product supplies weren't very much lower even though refinery use fell 1.2 percentage points," said Gene McGillian, analyst at Tradition Energy.

The oil price initially bounced after data showed US jobless claims fell more than expected to a 10-month low of 512,000 but oil's price gains were short-lived.

Analysts said US monthly jobs data on Friday will be more comprehensive and is likely to give prices a steer.

US employers in October cut payrolls by the smallest amount in 14 months as the economy's resumption of growth boosted optimism, but the jobless rate rose to a 26-year high, a Reuters survey predicts.
