Crude oil rebounded from the lowest close in almost two months, today, after U.S. crude inventories declined and as investors speculated that recent losses were excessive. Prices had fallen 1.5 percent, yesterday, the third consecutive day of declines, over concern that the European debt crisis may worsen and derail the global economy. Spaniards held protests and Greek police fired tear gas when a general strike turned violent. Analysts said the turbulence in Spain and Greece was dampening risk appetite. So oil for November delivery gained 91 cents, to 90.89 dollars a barrel in electronic trading on the NYMEX. Prices are down 3.9 percent this month, and up 6.9 percent this quarter. Brent oil for November settlement rose 96 cents, to 111 dollars a barrel on the London-based ICE Futures Europe exchange.
