Oil prices briefly spiked more than $25 a barrel Monday, Sept. 22, 2008, 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. (AP Photo/Seth Perlman, file)
