Japan's stock market plummeted 9.4 percent — its biggest one-day drop in 21 years — Tuesday as investors rushed for the exits on deepening fears over the global financial crisis.
The benchmark Nikkei 225 index nose-dived 952.58 points to 9,203.32, a five-year low. That was its third-biggest drop in percentage terms and largest plunge since October 1987.
The massive sell-off in Tokyo follows a plunge on Wall Street Tuesday, when the Dow Jones industrial average lost more than 5 percent despite steps by the Federal Reserve to reinvigorate dormant credit markets.
"Selling on Wall Street triggered further selling in Tokyo. It's like a chain reaction," said Kazuhiro Takahashi, general manager at Daiwa Securities SMBC Co. Ltd.
"No one knows the bottom of the ongoing financial crisis, and investors were really spooked by growing uncertainty over the global credit crisis," he said.
Selling accelerated as investors were pessimistic that the finance ministers and central bankers from the Group of Seven industrialized nations would announce any effective measures at their meeting in Washington on Friday to tackle the global financial crisis, Takahashi said.
"Investors were taking a wait-and-see approach over the upcoming meeting, but today's massive selling indicated that they were not so hopeful for concrete action by the G7," he said.
The Nikkei index has lost a staggering 24 percent in the last two weeks.
Among biggest losers, Toyota Motor Corp. plunged almost 12 percent to 3,280 yen on media reports that Japan's top automaker's operating profit would fall 40 percent this fiscal year through March due to sluggish demand in the U.S. market.
Toyota's rival, Nissan Motor Co., also dropped 9.9 percent, to 501 yen. Honda Motor Co. lost 10.31 percent to 2,305 yen.
The dollar briefly fell below the 100-yen level for the first time in six months as jittery investors dumped the greenback.
"Institutional investors are selling the dollar. Investors are simply spooked by a meltdown on Wall Street and its severe impact on the global market," said Mitsuru Sahara, vice president of foreign exchange division at Bank of Tokyo-Mitsubishi UFJ Ltd.
The dollar fell as low as 98.58 and was trading at 100.21 yen in Tokyo late afternoon trade, down from 101.38 yen in New York late Tuesday.
Among other stocks, Sony Corp. plunged 12.3 percent to 2,385. Toshiba Corp. also fell 7.2 percent to 359 yen.
Mizuho Financial Group shed 7.7 percent to 361,000 yen.
The broader Topix index dropped 8.04 percent to 899.01.
