NEW YORK, April 3 (Reuters) - Oil slipped on Thursday after weak U.S. jobs data intensified worries among investors that an economic slowdown could cut deeply into energy demand in the world's top consumer nation.
U.S. crude <CLc1> settled down $1.00 at $103.83 a barrel, while London Brent crude <LCOc1> dropped $1.23 to $102.52.
The losses came after U.S. data showed jobless claims were the highest since 2005, stoking fears of a significant economic slowdown that could further weaken consumption of fuels like gasoline and diesel.
"With the U.S. apparently sliding into a recession, oil market rallies will probably not derive as much strength from gasoline this year," Jan Stuart, economist with UBS, said in a research note.
Oil prices have quintupled since 2002 and remain within range of the record $110.80 hit last month as generally tight global inventories, strong demand from developing Asian economies and a weak U.S. dollar spurred a rush of investment in commodities markets.
But the market has pulled back since the peak on growing uncertainty over future demand -- a factor that has led OPEC to hold the line on its output cuts.
"We are obviously worried about North America's economy slowdown, which could eventually have an effect on demand, but there could be some compensation as countries like China and India increase their demand for crude," said Ecuadorean Oil Minister Galo Chiriboga.
Federal Reserve Chairman Ben Bernanke on Wednesday conceded for the first time that the U.S. economy may fall into recession in the first half of 2008.
Meanwhile, a report from the U.S. Energy Information Administration released Wednesday showed oil demand in the United States over the first 13 weeks of the year down more than 479,000 barrels per day (bpd) compared to a year ago.
"This remains a nervous and volatile market," said Peter Beutel, president of Cameron Hanover.
Tempering the losses, dealers continued to watch supply problems in the Middle East and Africa.
In Nigeria, a fire at the country's major oil export pipeline kept burning for a fifth day. The operator, a Royal Dutch Shell venture, said output and exports were unaffected.
Similar pipeline fires at Shell's pipeline last year led to partial losses of supplies from Africa's largest oil exporter.
In Iraq, officials said they had partially restarted output from southern oil fields that pump around 100,000 barrels per day after they were shut by a bomb attack on a pipeline last week. [
