Crude oil dips under $50 a barrel, lowest since April 2009

New York: The selloff in global oil markets showed little signs of slowing in the new year, with prices down as much as 6% on Monday, the lowest since spring 2009, as fears deepened a supply glut that has vexed the market for six months would continue. US crude crashed below $50 a barrel while benchmark Brent tumbled under $53 after data showed Russian oil output at post-Soviet era highs and Iraqi oil exports near 35-year peaks.

US driller ConocoPhillips added to the bearish mood by announcing it struck first oil at a Norwegian North Sea project.

Top crude exporter Saudi Arabia revealed it made deep cuts to its monthly oil prices for European buyers, the sixth time since June it has slashed prices, corresponding with the rout in crude futures markets over the period. Analysts read the latest cut as reflecting Saudi Arabia's fierce defence of its market share. The Organization of the Petroleum Exporting Countries kingpin also trimmed its prices for US refiners for a sixth straight month, while raising rates for Asia.

The euro's tumble to 2006 lows, and slower-than-expected growth in US manufacturing, completed the perfect storm for the oil markets. "There's no doubt that we have a combination of supplies hitting their zenith at a time when demand is weakening," said Phil Flynn, an analyst at Price Futures Group in Chicago. U.S. crude settled down $2.65, or 5%, at $50.04 a barrel, and was at a post-settlement low of $49.77 by 3:15 p.m. ET (2015 GMT). The last time US crude traded below $50 was in April 2009. Front-month Brent closed down $3.31, or almost 6%, at $53.11 a barrel. It dropped earlier to $52.66, its lowest since May 2009. Oil has plunged nearly 55% in value since June, when Brent traded above $117 a barrel and US crude above $107.

The selloff, which began on concerns of oversupply in high quality US shale crude, accelerated after the OPEC meeting in November, when Saudi Arabia ruled out production cuts as a means of boosting prices. The kingdom reasoned that reducing output will hurt its market share instead. Some traders seem certain that US crude will be trading in the $40 region later in the week if weekly oil inventory numbers for the United States on Wednesday show another supply build.

"We're headed for a four-handle," said Tariq Zahir, managing member at Tyche Capital Advisors in Laurel Hollow in New York. "Maybe not today, but I'm sure when you get the inventory numbers that come out this week, we definitely will." Open interest for $40-$50 strike puts in US crude have risen several fold since the start of December, while $20-$30 puts for June 2015 have traded, said Stephen Schork, editor of Pennsylvania-based The Schork Report. Russia's oil output hit a post-Soviet high last year, averaging 10.58 million barrels per day (bpd), up 0.7% thanks to small non-state producers, Energy Ministry data showed.

Iraq's oil exports were at their highest since 1980 in December, an oil ministry spokesman said, with record sales from the country's southern terminals. The Russian and Iraqi data overshadowed reports of drops in Libya's oil output because of conflict in that country. Libya's oil output has fallen to around 380,000 bpd after the closure of the OPEC producer's biggest oil port, Es Sider, along with another oil port, Ras Lanuf.
