HONG KONG, Sept 29 (Reuters) - The U.S. dollar edged up and gold prices slipped on Monday as Washington lawmakers prepared to vote on a plan to save the financial system from ruin, but Asian stocks fell on persistent questions on its effectiveness.
The proposal to establish a $700 billion fund to buy illiquid securities will be sent to Congress later on Monday after days of tense negotiations and compromises. At the same time, instability in Europe's bank industry has worsened, with the Belgian, Dutch and Luxembourg governments forced to rescue financial firm Fortis <FOR.BR> over the weekend. [
]In addition, the British government will take over mortgage lender Bradford & Bingley <BB.L>, people in the bank industry familiar with the matter told Reuters, sending the pound and the euro lower across the board.
After the U.S. financial system nearly imploded this month in the wake of the bankruptcy of Lehman Brothers <LEHMQ.PK>, the rescue of American International Group <AIG.N> and the demise of the investment banking model, the plan to stem the crisis met strong resistance from some policymakers who balked at cutting such a big check to the White House.
"Now the devil is in the details. There have been so many constraints put on the deal that any one of those could completely limit its effectiveness," said Tim Rocks, equity strategist with Macquaries Securities in Hong Kong.
"Ultimately for the banks to believe each other again, trust each other and start lending, they just all need more capital. The big question is whether this plan actually achieves that."
Hong Kong's Hang Seng index led the region lower, falling 2.1 percent largely on weakness in financial sector shares. Ping An Insurance stock <2318.HK> dropped 9 percent after the bailout of Fortis, in which the second-largest Chinese insurer has a 5 percent stake.
Japan's Nikkei share average <
> slipped 0.5 percent, erasing earlier gains, as exporter stocks like Toyota Motor Corp <7203.T> accelerated their decline.The MSCI index of Asia-Pacific stocks outside of Japan <.MIAPJ0000PUS> fell 1.4 percent, after posting four consecutive weeks of declines.
The December U.S. S&P 500 future was down 0.9 percent <SPc1>, reversing initial gains on news the plan was set to be presented in the House of Representatives.
SAFETY VS RISK
Washington's bailout package, though unpopular with the public and doubted by some analysts, is the biggest effort yet by the U.S. government to ease the worst global financial crisis since the Great Depression. Yet it alone has not been enough to reverse a powerful move by global investors to purge their portfolios of risk.
"The package will improve liquidity in the system. But I don't think lenders are going to go out carte blanche and provide new capital to the market in an aggressive way," said Leigh Gardner, head of equities distribution for ABN AMRO in Australia. "The availability of credit has definitely changed, and this is not going to avert that situation."
For investors, safety is highly prized, and for now that is being found in U.S. assets and highly-liquid short-term funds. Last week, U.S. equity funds took in $10 billion in fresh investment and money market funds saw $11 billion in new money, according to Boston-based EPFR Global, a research firm that tracks $10 trillion in assets.
Global emerging market equity funds posted inflows for the first time in nine weeks, but Eastern European, Latin American and Asia ex-Japan funds all recorded redemptions.
The euro fell 0.1 percent to $1.4505 <EUR=>, down almost 4 cents from a one-month high hit a week ago.
Sterling dropped 0.6 percent to $1.8283 <GBP=> after touching a one-month high on Thursday.
The dollar was largely unchanged against the yen at 106.30 <JPY=> and up 0.1 percent against the Swiss franc at 1.0952 francs <CHF=>.
CAUTION REIGNS
Some measures of money market tension and fear among investors have come down from extreme levels reached in the last few weeks, but they remain elevated. The spread of the rate on 3-month eurodollar futures over the 3-month U.S. Treasury bill yield, also known as the TED spread <TED>, narrowed to 245 basis points from 272 basis points late on Friday.
Still, the cost of non-investment grade credit protection against default or corporate restructuring in Asia, as measured by the Asia iTRAXX high-yield index <ITAHY5Y=IE>, was not far below all-time highs reached two weeks ago. And financial firms continued to battle for survival of the fittest.
Wachovia Corp <WB.N> was in talks with rivals Citigroup <C.N> and Wells Fargo <WFC.N> over a possible takeover, sources said. [
]"Markets are likely to take a cautiously positive tone to the plan and the much greater prospect of passage through Congress," Calyon analysts said in a note.
"Nonetheless, there remain many questions about agreeing valuations on toxic assets as well as many other operational issues. Any easing in risk aversion could be limited until its effectiveness becomes clearer," they said.
Spot gold <XAU=> fell 0.7 percent to $877.50 an ounce, though it is up around 14 percent in the last two weeks, living up to its traditional role as a safe haven. (Additional reporting by Sonali Paul in MELBOURNE; Editing by Lincoln Feast)
