Oil prices on Tuesday reached the $91-a-barrel mark in light trading as strong demand and limited supply continues to push up prices toward the end of the year.
Oil for February delivery increased 27 cents to $91.27 a barrel in New York Mercantile Exchange trading Tuesday. It had been trading at about $81 a barrel about a month ago.
With demand from countries such as China and India expected to increase next year, oil may surpass the $100 level in early 2011, the Associated Press reported, citing commodities analysts. Higher oil prices are also pushing up gas prices. The national average gas price for regular unleaded is $3.05 a gallon, up about 18% from a year ago, according to AAA.
