HONG KONG, Feb 17 (Reuters) - Asian stocks fell on Tuesday, with Japan's Nikkei sinking to a near 4-month closing low, while the U.S. dollar surged as investors scrambled for safety from deteriorating global economic conditions and volatile banks.
Major European stocks were expected to open as much as 0.4 percent lower, financial bookmakers said, after Moody's Investors Service warned severe recessions in emerging Europe will pressure financial strength ratings of some Western European banks. [
]Fiscal strains across Portugal, Ireland, Greece and Spain gave dealers more incentive to push the euro to a two-month low against the dollar and scoop up U.S. Treasuries and gold -- both viewed by investors as places of refuge during market turmoil.
"The risk aversion trades are likely to keep making money -- albeit amid volatility -- until new measures are unveiled by governments and central banks in key economies," said Dariusz Kowalczyk, chief investment strategist with SJS Markets in Hong Kong, in a note.
"Judging by the insufficient policy response so far, the near-term market outlook remains negative."
Countless economic stimulus packages and open promises to take more action by policymakers have so far all been met with disappointment by investors, with not even the $787 billion rescue bill passed this week in Washington helping sentiment.
Exports across Asia have collapsed and the latest Reuters Tankan poll of Japanese manufacturers shows confidence remains mired near record lows. [
].Japan's Nikkei fell 1.35 percent, closing at the lowest since October 2008, as financial shares such as banks and property firms slid on continued credit worries.
Japanese Finance Minister Shoichi Nakagawa said on Tuesday he would resign after being forced to deny he was drunk at a G7 news conference, dealing a fresh blow to unpopular Prime Minister Taro Aso in an election year. The yen slipped on the news, but did not faze stocks.
Shares of top lender Mitsubishi UFJ Financial Group <8306.T> lost 4 percent, in the wake of a big loss at HBOS, a unit of Britain's Lloyds <LLOY.L>.
Losses in the energy, technology and financial sectors dragged the MSCI index of Asia-Pacific stocks excluding Japan <.MIAPJ0000PUS> down 3.2 percent.
Hong Kong's Hang Seng index <

Investors were awaiting news from General Motors Corp <GM.N> and Chrysler LLC <CBS.UL>, which were expected to hand in their restructuring plans by a Tuesday deadline, a requirement after receiving $13.4 billion in U.S. government aid.
"Investors are selling stocks not only in Japan but in other Asian markets as they wait for restructuring plans from GM and Chrysler. There's a view in the market that they might not be able to submit it on time," said Soichiro Monji, chief strategist at Daiwa SB Investments in Tokyo.
SCHIZOPHRENIC
The dollar shot higher as investors cut down risks and held on to liquidity amid volatile global markets.
The yen, which has often gained during periods of heightened market stress, slid against dollar and briefly extended losses after Nakagawa said he would resign after parliament passed budget bills. [
]Heavy euro selling tripped automatic sell orders planted just below $1.27 and the currency fell more than 1 percent to about $1.2630 <EUR=>, its lowest since early December.
The dollar rose to around 92.75 yen <JPY=>, its strongest since early January.
Emerging Asian currencies broadly weakened against the dollar.
"We believe there is more to come as the schizophrenic gap between rather resilient Asian currencies recently and ugly economic data closes," said Sebastien Barbe, currency strategist with Calyon in Hong Kong, in a note.
The renewed focus on safety funnelled investors into U.S. government debt, pushing yields lower across maturities. The benchmark 10-year yield <US10YT=RR> tumbled to 2.81 percent from about 2.89 percent late on Friday.
The 2-year yield fell to 0.89 percent from 0.97 percent.
Japanese government bonds also rose on the back of the rally in Treasuries, with the March 10-year future up by 0.38 point <2JGBv1>.
U.S. crude futures <CLc1> for March delivery fell to $36.76 a barrel, 75 cents off last Friday's settlement. London Brent crude for April <LCOc1> rose 72 cents to $44 in thin trading.
The sharp declines in equity markets and rush to safety sparked strong demand for gold. The spot market price climbed to a seven-month high of $958.80 an ounce <XAU=>.
