Oil prices fell for a seventh session in a row today, coming close to 11-year lows.
The falls came on growing fears that the global oil glut would worsen in the months to come in a pricing war between leading OPEC and non-OPEC producers.
Brent crude fell by 3.4% to below $36.70 a barrel for the first time since December 2008 and US West Texas Intermediate sank 2.5% below $34.70 a barrel.
Brent traded less than 50 cents above the lows last seen during the 2008 financial crisis of $36.20 a barrel.
If Brent falls below that level, that will be its lowest since mid-2004, when talk of a commodity super-cycle was only beginning. WTI's financial crisis low was $32.40 in December 2008.
Both benchmarks have fallen every day since the Organisation of the Petroleum Exporting Countries on December 4 abandoned its output ceiling. In the past six sessions, they have shed more than 13% each.
OPEC has been pumping near record levels since last year in an attempt to drive higher-cost producers such as US shale firms out of the market.
New supply is likely to hit the market early next year as OPEC member Iran ramps up production once sanctions are lifted as expected following the July agreement on its disputed nuclear programme.
Iran's crude oil exports are set to hit a six-month high in December as buyers ramp up purchases in expectation that sanctions against the country will be lifted early next year, according to an industry source with knowledge of tanker loading schedules.
Iranian news agency Shana quoted the manager director of Iran's Central Oil Fields Company, Salbali Karimi, as saying Iran's cost of production stood $1-$1.5 per barrel, in a clear indication it would ramp up output in any price scenario.
Gulf producers and Russia have previously said they would not cut output even if prices fell to $20 per barrel.
On Friday, the International Energy Agency (IEA) that the global supply glut was likely to deepen next year and put more pressure on prices. But it said it did o't believe the world would run out of storage capacity.
