3:15PM EST: Oil prices spiked more than $25 a barrel Monday – the biggest one-day price jump ever – as anxiety over the government’s $700 billion bailout plan battered the dollar and touched off frenzied buying of safe-haven investments including crude.

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 somewhat to trade at $122.60,up $18.05. The contract was set to expire at the end of the day, adding to the volatility; the October price began accelerating sharply in the last hour of regular trading.

Crude has gained about $40 in a dramatic four-day rally that has at least temporarily halted oil’s steep two-month slide below $100. At this rate, crude is within striking distance of its all-time record of $147.27, reached in July.

Oil’s sharp gains came as energy traders grappled with the implications of the government’s proposed $700 billion initiative to stem the U.S. financial crisis by absorbing billions of dollars of banks’ bad mortgage-related securities. Anxiety over the plan also sent stocks sharply lower Monday; the credit markets were calmer than they were last week, but still showing the effects of investors’ nervousness.

There is still much uncertainty about what impact the U.S. rescue plan will have on energy demand. Oil’s run-up near $150 a barrel in July and a weak U.S. economy has forced Americans to cut back on their driving and led business to scale down operations. Though pump prices have eased from record levels above $4 a gallon, they remain expensive, and more softening in the economy would likely further curtail energy use in the world’s thirstiest consumer.
