The Dow closed Thursday down 512.76 points, at 11,383.68. It was the steepest point decline since Dec. 1, 2008.
Japan's Nikkei 225 stock average slid 3.7 percent to 9,303.95 and Hong Kong's Hang Seng dived 4.8 percent to 20,844.59. China's Shanghai Composite Index lost 1.9 percent to 2,633.52.Europe fared no better, with stocks falling across regional markets and Italian and Spanish bonds trading at levels that threaten their ability to raise money in the bond markets to pay off debts.

Oil extended sharp losses Friday to fall below $86 a barrel amid expectations a slowing global economy will undermine demand for crude.
"Losses today have been indiscriminate," said IG Markets strategist Ben Potter in a report. "The big question on everyone's mind is what will happen across European and U.S. markets tonight and will there be any form of emergency policy response?"MoneyWatch: Will recent signs of weakness prompt the Fed to act?

Thursday's decline was the ninth-worst by points for the Dow. In percentage terms, the decline of 4.3 percent does not rank among the worst. On Black Monday in 1987, for example, the Dow fell 22 percent.

"It's a general fear that is clouding the markets at the moment," Kaan said.
