The historic carnage on Wall Street spread to Asia today, with stocks plunging after Congress rejected a rescue plan that investors had hoped would bolster volatile financial markets.
All major stock markets in the region tumbled sharply, succumbing to heightened fears of a broader global credit crisis.
Japan's benchmark Nikkei 225 index shed more than 544 points, or 4.6 percent, to 11,199.07 after losing 1.3 percent Monday.
Key indices in Australia and New Zealand were down about 4 percent, Seoul's Kospi lost 3.5 percent, and Hong Kong's Hang Seng index declined 5.5 percent.
The weighted price index of the Taiwan Stock market, which was closed Monday because of a typhoon, fell 6.1 percent.
The selling in Asia came after world stock markets -- including the London Stock Exchange, Germany's DAX, France's CAC 40 and the Irish Stock Exchange -- tumbled Monday amid a flurry of government bank rescues.
The markets were responding to news that Dutch-Belgian banking giant Fortis NV was partly nationalized with a 11.2 billion euro ($16.4 billion) rescue from the governments of Belgium, the Netherlands and Luxembourg, after investor confidence in the bank disappeared last week.
Also, the British government nationalized mortgage lender Bradford & Bingley, taking over its 50 billion pound ($91 billion) mortgage and loan books. In a similar move, the Icelandic government bought a 75 percent stake in Glitnir, the country's third-largest bank, for 600 million euros ($878 million) to ensure broader market stability after it suffered liquidity issues.
