NEW YORK — Oil prices briefly spiked more than $25 a barrel Monday, shattering the record for the biggest one-day gain as unease about the government's $700 billion bailout plan pummeled the dollar and spurred investors to buy safe-haven assets. An expiring crude contract added fuel to the frenzied rally.

Light, sweet crude for October delivery jumped as much as $25.45 to $130 a barrel on the New York Mercantile Exchange before falling back to settle at $120.92, up $16.37. The contract expired at the end of the day, adding to the volatility as traders rushed to cover positions; the October price began accelerating sharply in the last hour of regular trading, a common occurrence when a contract is about to go off the board.

Still, the rally, which shattered crude's previous one-day price jump of $10.75, set June 6, showed the intensity of emotion in the market. The Nymex temporarily halted electronic crude oil trading after prices breached the $10 daily trading limit. Trading resumed seconds later after the daily limit was increased.
