LONDON, Sept 23 (Reuters) - Global stocks fell on Tuesday and the dollar struggled, weighed down by investor worries about political resistance to Washington's $700 billion bailout plan and whether the deal will work.
Worries about delays as the Bush administration and Congress haggle over details of the package paved the way for a negative start on Wall Street as markets awaited U.S. Treasury Secretary Henry Paulson's questioning by the Senate Banking Committee. [
]Initial exuberance about the plan to buy up toxic mortgage debt has given way to concerns about how the U.S. government would fund it and whether the package would be enough to boost the world's biggest economy, which is facing a recession.
"The focus does remain on the uncertainty surrounding the U.S. bailout package, the details of it and how exactly the final version will look. The recent developments in the U.S. suggest the debating process will be longer than expected," said David Powell, G10 FX strategist at Bank of America in London.
Nervous investors were also eyeing crude oil, which soared nearly 16 percent in its biggest one-day gain ever on Monday due to the expiry of the front-month futures contract and weakness in the dollar.
But November crude oil futures <CLc1> fell $2.47 to below $107 a barrel.
The FTSEurofirst 300 <
> index of top European shares shed 2.1 percent, extending Monday's 2.1 percent slide, while Germany's DAX < > fell 0.8 percent.This followed a decline of 2.2 percent for Asian equities excluding Japan <.MIAPJ0000PUS>. Japanese financial markets were closed for a holiday on Tuesday.
MSCI's world equity index <.MIWD00000PUS> shed 0.6 percent.
U.S. stock futures <SPc1><DJc1><NDc1> were all in the red.
"It'll take some months before people can have confidence again in the financial system and in financial counterparties," said Hans-Juergen Delp, equity strategist at Commerzbank in Frankfurt.
Safe haven government bonds benefited from weakness in equities, pushing yields lower. The 10-year Bund yield <EU10YT=RR> fell 3.2 basis points to 4.219 percent, while the benchmark 10-year U.S. Treasury note yield <US10YT=RR> slid 6.1 basis points to 3.79 percent.
PRESSURE SEEN FOR DOLLAR
The dollar pared early gains versus the Japanese currency to be up just 0.2 percent at 105.59 yen <JPY=>, while the euro slipped 0.2 percent to $1.4761 <EUR=>, but was well off the session low of $1.4681.
"While this bailout package does remove some of the systemic risk from the U.S. financial system, it's also clear that the potential rise in U.S. debt ratios and the effect on their fiscal balance will hurt the dollar in the medium term," said Dankse Bank currency strategist Kasper Kirkegaard.
More weakness in the euro zone economy was revealed by a closely watched survey showing the services sector in Germany, the region's biggest economy, edging into contraction in September for the first time since January and manufacturing industry slumping to its weakest performance in over five years.
However, all eyes are on Paulson and Federal Reserve Chairman Ben Bernanke who will testify before the Senate Banking Committee at 1330 GMT.
"The focus for the market will be on further details that Paulson offers, if any, about the structure of the proposed fund to purchase 'troubled assets'," said analysts at Barclays Capital.
Major central banks around the world have been pumping cash to improve interbank money markets, which practically seized up last week following the collapse of Lehman Brothers.
While there have been signs of improved liquidity, tensions remain high in the interbank money markets as financial institutions stay wary of lending to one another.
The overnight dollar London Interbank offered rate (Libor) was fixed at 2.95 percent on Tuesday, down a touch from around 2.97 percent on Monday and well off the high near 6.5 percent set last week.
Many market participants remain shellshocked after the last two extraordinary weeks in which Fannie Mae <FNM.N> and Freddie Mac <FRE.N> were effectively nationalised, Washington bailed out insurer American International Group <AIG.N> and Bank of America <BAC.N> bought Merrill Lynch <MER.N>.
