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 carnage was also brutal in Hong Kong, where the blue chip Hang Seng index plunged 5.6 percent to 15,871.

The selling tide was so huge that the Paris stock exchange briefly suspended calculating the benchmark CAC-40 index amid a massive influx of sell orders that caused it to plummet nearly 8.2 percent at one stage. Orders passed a threshold of 35 percent of the total market value of the 40 blue-chip stocks that make up the index, triggering an automatic halt in the calculation under exchange rules, exchange spokeswoman Frederique Vigezzi said.

"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.

"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.
