CRUDE oil traded near a one-week low in New York amid speculation a report today will show US supplies last week rose to their highest in almost seven years.
Stockpiles probably gained for a sixth week, climbing 0.8 per cent in the period ended March 17, according to a survey. This would increase inventories to their highest since April 1999.
"People are talking about a glut now," said Mark Waggoner, president of Excel Futures in Huntington Beach, California.
Crude oil for April delivery was at $US60.05 a barrel, down US37c, in after-hours electronic trading.
The contract plunged $US2.35, or 3.7 per cent, to $US60.42 on Monday, the biggest one-day decline since August 17 and the lowest close since March 10.
Oil futures on January 23 rose to $US69.20, the highest since September 2, on fear that Iran, the world's No.4 producer, could cut exports if the UN imposes sanctions to stop the Islamic Republic's nuclear research.
Insurgent attacks in Nigeria have cut production in the No.5 oil supplier to the US.
Petrol stockpiles in the US have fallen in the past two weeks and demand is running 2.5 per cent higher than a year ago, the Energy Department said.
"When prices are at these heights you need fresh worrisome news to keep us moving higher," John Kilduff, vice-president of risk management at Fimat USA in New York, said on Monday. "We'll be paying attention to gasoline because there is a question about supplies as summer approaches."
The US, the world's biggest oil consumer, uses about 10 per cent of the global supply to make petrol. Demand for the motor fuel usually peaks between the Memorial Day holiday in late May and Labor Day in early September.
Petrol stockpiles fell in the US Energy Department's past two reports as refiners closed refineries for seasonal maintenance and demand rose to its highest this year.
