Stocks in Asia fell sharply Tuesday. Hong Kong's Hang Seng index plummeted nearly four percent, while Japan's benchmark Nikkei 225 index fell two percent to its lowest level in more than three months.
 
Across Asia, analysts say investors dumped shares, worried about the health of the U.S. financial sector and its effect on Asian companies.
 
Kingston Lin, associate director at Prudential Brokerage in Hong Kong, says the U.S. government's move to help troubled mortgage lenders Fannie Mae and Freddie Mac failed to dispel those fears.
 
"It's useless, because the confidence is not coming back. So I think the market will continue to drop," he said.

Shares in China's biggest bank, ICBC, also declined more than five percent.
 
Taiwan's weighted index closed four and a half percent lower to a 22-month low. Taiwan financial institutions hold an estimated $23 billion in Fannie Mae and Freddie Mac bonds.
 
South Korea's KOSPI fell 3.2 percent, to its lowest close in 15 months.
