LONDON, July 10 (Reuters) - U.S. crude prices sank a dollar to below $60 a barrel on Friday, their lowest since mid-May and were poised for their biggest weekly fall since January as traders focused on economic uncertainty.
The latest report from the International Energy Agency predicted an increase in oil consumption in 2010, but expected it to stay negative in 2009 and saw limited demand for OPEC crude. [
]U.S. light crude for August delivery <CLc1> was trading $1.13 a barrel lower at $59.28 a barrel by 1154 GMT, its lowest since $58.55 on May 19.
London Brent crude <LCOc1> was down 96 cents at $60.14 a barrel.
Oil rose to more than $73 at the end of June, its highest level this year, but since then the market has dropped around $10 as expectations of a swift economic recovery faltered.
Although the IEA predicted world oil use would grow in 2010, it added that depended on expected economic recovery materialising.
Prices briefly edged higher immediately after the agency's report, but then resumed their slide.
"While 2010 oil demand and economic activity figures are expected to show better-than-expected growth, the world is still in for recession in 2009 and that is hard to reconcile with a high oil price tag," said Harry Tchilinguirian of BNP Paribas.
"The oil market is beginning to focus again on its weak fundamentals."
Oil has fallen in six of the previous seven sessions. So far this week, prices have dropped nearly 10 percent, slightly less than an 11 percent weekly drop in January.
The latest wave of selling began after much worse than expected U.S. unemployment data [
] on Thursday and has been sustained by a steady stream of negative economic news.An announcement this week from U.S. regulator the CFTC that it was considering tighter controls on excessive speculation in the commodity markets added to the bearish mood, although analysts said it would take months to implement changes. [
]"A strong incentive was created for market participants of all types to draw back from the market, particularly from the long side of U.S. markets," Barclays Capital said in its weekly oil review.
One supportive factor for the oil market has been disruption of supplies by militants in Nigeria. That has helped tighten OPEC supplies, although the group's discipline has declined to roughly 70 percent from an estimated peak of 80 percent of promised supply curbs earlier this year.
But some analysts thought news that Nigerian President Umaru Yar'Adua could be freed in the next few days after the revel leader welcomed the government's amnesty offer could lead to less frequent supply disruptions. [
