Brent oil hits 11-year low as global supply balloons

U.S. crude remained above its 2009 low and settled up a penny a barrel as traders squared positions ahead of the January contract's expiration. The February contract declined and analysts expect stockpiles to build again this week, signaling further oversupply in already glutted market.

Concerns about swelling global crude supply and slow demand sparked by economic weakness in China have been recurring themes during this year's rout. Analysts said the market was still testing for a bottom.

"The key in finding the bottom of the market comes in a tightening of the supply side," said Gene McGillian, senior analyst at Tradition Energy in Stamford, Connecticut.

OPEC and Russia will keep producing at high volumes, increasing pressure on U.S. producers to throttle back production, he said.

"I think we're getting ready for another round of capex cuts in North America," he said.

Heating oil futures weighed down the crude complex, hitting a new July 2004 low warmer-than-expected temperatures have hit seasonal demand.

"The market is waiting for the next announcement," said Tyche Capital Advisors senior research analyst John Macaluso. "The equity markets are waiting on crude oil, and crude oil is waiting for a bounce before shorts will come back into the market."

Crude short-sellers will be reluctant to return before U.S. crude recovers to $35.50, he said.
