WASHINGTON (AP) – Oil prices settled at a record high above $70 a barrel on Monday, rising more than $1 on concerns about supply disruptions in Nigeria and diplomatic tensions between the West and Iran over Tehran’s nuclear ambitions.

So long as these and other geopolitical issues persist, analysts said it will be difficult for prices to fall too far – unless there is a significant drop-off in demand, which they aren’t yet seeing. In the short-term, oil prices could climb above $75, they said.

“Where the top is is pretty hard to say at this point,” said New York-based oil broker Tom Bentz.

Light sweet crude for May delivery settled at $70.40 a barrel on the New York Mercantile Exchange, an increase of $1.08 from Thursday’s close and 59 cents above the previous closing record set last August. The exchange was closed Friday.

The gasoline market was also delivered a jolt on Monday, with Nymex gasoline futures jumping 6.18 cents to settle at $2.1697 a gallon – the highest level since late September. At the retail level, the nationwide average for regular unleaded is $2.78 per gallon, or 55 cents higher than last year, according to the Energy Department.

Crude futures first surpassed $70 a barrel on Aug. 30 in the immediate aftermath of Hurricane Katrina. Prices climbed as high as $70.85 a barrel during the day, and then settled at $69.81.

On an inflation-adjusted basis, oil prices would have to rise above $90 to exceed the all-time highs set a quarter century ago when supplies became tight in the aftermath of a revolution in Iran and a war between Iraq and Iran. In 2005 dollars, the average price of crude in 1980 was just under $77 a barrel.

ABN Amro broker Lee Fader said the trigger for Monday’s rally was “heightened fear about military action” against Iran, which has said it would go ahead with plans to enrich uranium, defying the United States, Europe and United Nations nuclear experts. Iran says its nuclear ambitions are peaceful, but the West fears the country is intent on arming itself with nuclear weapons.

“If somehow this got resolved diplomatically,” Fader said, “that would definitely take a few dollars off” the price of crude oil.

The market was also driven by the disruption of crude supplies in Nigeria, where more than half a million barrels a day of crude production capacity are being blocked due to militant violence. There has been production added in other parts of the country, though, and that has offset the impact. According to Platts, Nigeria produced 2.15 million barrels per day in March, down from 2.37 million barrels per day in February.

In the Gulf of Mexico, more than 300,000 barrels a day remains shut because of damage from last summer’s vicious hurricane season.

Underlying the nervousness about supplies in the Middle East, Africa and the U.S. is the global industry’s thin margin for error. Worldwide demand is expected to average 85 million barrels per day in 2006, leaving just 1.9 million barrels per day of excess production capacity that could be called upon in an emergency, according to Cambridge Energy Research Associates.

CERA oil analyst James Burkhard said this supply cushion shows no sign of growing anytime soon. “So far we’re not at the point where demand is pulling back,” he said.

However, global oil demand is growing at a slower rate than last year, according to the International Energy Agency.

The U.S. Energy Department forecast last week that gasoline demand would rise this summer by 1.5 percent to 9.4 million barrels per day, and that prices would average $2.62 a gallon from now through September.

On London’s ICE Futures exchange, Brent crude oil futures settled 89 cents higher at a record $71.46 a barrel.

In other Nymex trading, heating oil futures rose 3.98 cents to close at $2.0229 a gallon while natural gas finished 44.2 cents higher at $7.577 per 1,000 cubic feet.
