U.S. crude and Brent futures dropped to fresh 5-1/2-year lows on Monday as worries about a surplus of global supplies amid weak demand continued to drag on oil markets. OPEC's decision in November to maintain output had earlier accelerated oil's losses, while record-high Russian production and the highest Iraqi exports since 1980 added to the concerns about oversupply. The two oil benchmarks, Brent and West Texas Intermediate, have now lost more than half of their value from peaks hit in mid-2014. U.S. crude CLc1 slid as low as $51.40 a barrel on Monday, its lowest since May 2009, and at 0535 GMT was at $51.60 a barrel, still down $1.09. February Brent crude LCOc1 dropped as low as $55.36 a barrel, also its lowest since May 2009, before edging back to $55.51, down 91 cents. Lacklustre economic data from the United States on Friday fuelled worries about the state of the global economy and the strength of oil demand. "Oil demand is unlikely be robust this year when we look at the state of economies in China, Japan and Europe," said Yusuke Seta, a commodity sales manager at Newedge Japan. A weak euro may also have contributed to further oil losses as it reduces the purchasing power of euro holders for dollar-denominated oil. "Theoretically speaking, a weaker euro puts downward pressure on Brent, although quantitative easing in the euro zone could possibly put more liquidity in the region, which may subsequently flow into Brent," Seta said. Ample supply and slowing demand could push Brent into a $50-$55 range, possibly during the first quarter of 2015, said a crude oil trader who declined to be named due to company policy, with WTI about $4 lower. Conflicts in Libya has reduced the OPEC producer's crude output to around 380,000 barrels a day, state-run National Oil Corp (NOC) has said. Fighting was reported near the country's biggest oil export port Es Sider in the east even as a week-long fire at the port's storage tanks was extinguished on Friday. Source : Reuters
