HONG KONG, Feb 24 (Reuters) - Asian shares fell to a three-month low on Tuesday and Japan's Nikkei index flirted with a 26-year low, as concerns grew about the global financial system, helping send safe havens such as the dollar higher.
Strong gains in Asian shares on Monday were erased as optimism over reports that the U.S. government could take a bigger stake in Citigroup <C.N> gave way to fresh questions about whether Washington is doing enough to stabilise the ailing banking and credit sectors.
European shares were seen sliding as well, extending a global rout that on Monday sent the Dow Jones industrial average <
> and the S&P 500 indexes to 12-year lows.Emerging Asian currencies continued their recent falls, with the South Korean won pounded again by fears about tight credit conditions amid the weakest global economy in decades.
"The problem is not with only one bank or one country. Investors are losing confidence, seeing U.S. and European stock markets continue to slide," said Hwang Chang-joong, an analyst at Woori Investment & Securities in Seoul.
Problems in the global financial system continue to multiply as massive credit losses and recession weigh on lenders. American International Group Inc <AIG.N> is in talks with U.S. officials for more aid, while in France the government is expected to provide more funding to two mutually owned banks. See [
]But policymakers have yet to convince investors they can successfully tackle the global financial woes that have ignited a worldwide recession.
The MSCI index of Asia-Pacific stocks outside Japan <.MIAPJ0000PUS> dropped at one point to its lowest since Nov. 26, and was down 2.3 percent as of 0645 GMT, thus erasing its 1.7 percent gain on Monday.
The gauge is now down about 13 percent for the year, and about 10 percent above its post-financial crisis low of 194.03 hit in November 21, which had marked a five-year low.
Japan's Nikkei average <
> slid 1.5 percent, threatening to breach levels that would put it at its lowest since 1982.Banking and financial shares led the declines across Asia. Shares in Japan's Nomura Holdings <8604.T>, the country's biggest brokerage, slumped 9.3 percent after it announced a big share sale to shore up its balance sheet.
U.S. regulators on Monday reinforced their willingness to provide extra funds to financial institutions that need them, as they look to begin assessing major institutions' capital needs on Wednesday under a new "stress test" program. [
]But any new government assistance to Citigroup could fuel speculation that Washington will need help other lenders as well, while doubts remain about government efforts to stabilise the plunging housing market, where the credit crisis began.
Key indexes in Seoul <
>, Hong Kong < > and Shanghai < > dropped more than 3 percent each, while Singapore <.FTSTI>, Taiwan < >, and India < > fell around 1 percent each.EMERGING CURRENCY HIT
Market uncertainty stands to benefit safer assets such as gold, which was range-bound on Tuesday but is expected to at some point surpass the record $1,030.80 hit last March, analysts said.
"Despite the correction going on, it is clear that gold is the only class of assets investors can put their money in," said Tatsufumi Okoshi, senior economist at Nomura Securities Co's financial and economic research centre in Japan.
"Stocks are hit hard, other commodities are down, and an expected fall in bond prices keeps new money from flowing into bonds," he said, referring to a glut of global government debt.
Emerging Asian currencies have been hit hard by the market turbulence. The won <KRW=> fell as low as 1,514.9 per dollar, down about 1.7 percent from Monday and bringing its losses so far this year to nearly 17 percent.
The won has been hit hard by a collapse in Asian exports and the economy's reliance on short-term overseas debt that needs to be refinanced amid tough market conditions.
Still Asian currencies have fared less badly than in parts of emerging Europe, which led central European policymakers to take the unprecedented step of joint verbal intervention on Monday to support their currencies. [
]The dollar rose as high as 95.23 yen <JPY=> as of midday, marking its highest against the Japanese currency since Dec. 1 and putting its move up 0.7 percent on the day.
The euro was range-bound at around $1.2715 <EUR=> compared to late U.S. trade on Monday.
The weak outlook for global demand also continued to undermine oil prices, sending oil futures <CLc1> down 32 cents to $38.11 a barrel, extending declines from the previous session.
Gold <XAU=> recovered from earlier falls to stay range-bound at $991.00 an ounce.
