Update: Oil hits 5-1/2-year low under US$55 on supply glut

[LONDON] Oil prices slumped to new 5-1/2-year lows on Monday on worries about a surplus of global supplies and lacklustre demand.

Russia's oil output hit a post-Soviet high last year, averaging 10.58 million barrels per day (bpd), up 0.7 per cent 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.

But oil producer group OPEC has decided not to cut output, opting to let the market find its own level.

The two crude oil benchmarks - Brent and US light crude, also known as West Texas Intermediate - have now lost more than half of their value since mid-2014.

Brent crude for February dropped as low as US$54.02 a barrel, down US$2.40 from Friday's close and its weakest since May 2009, before edging back to around US$54.50 by 1420 GMT.

US crude slid to US$50.55 a barrel on Monday, down US$2.14 and also its lowest since May 2009. "The easiest path for oil is down," said Carsten Fritsch, senior oil and commodities analyst at Commerzbank in Frankfurt. "Almost all market news and the fundamental backdrop are negative and it is difficult to see much upside at the moment."

Morgan Stanley analyst Adam Longson agreed, saying it was "hard to see much improvement in oil fundamentals near term". "New supply has entered the market, offsetting Libya woes. Additional exports are coming primarily from Russia and Iraq,"Longson wrote in a note to clients.

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.

Investors are also increasing bets on lower oil prices.

Open interest for US$40-US$50 strike puts have risen several fold since the start of December, while US$20-US$30 puts for June 2015 have traded, said Stephen Schork, editor of Pennsylvania-based The Schork Report.

Conflict in Libya has reduced the Opec producer's crude output to around 380,000 bpd, state-run National Oil Corp (NOC) has said.
