LONDON, Sept 23 (Reuters) - European shares ended sharply lower for the second straight day on Tuesday as investors fretted about the fate of a $700 billion financial sector rescue plan which the United States is trying to push through Congress.
The pan-European FTSEurofirst 300 <
> index ended 1.6 percent lower at 1,108.54 points, adding to a 2.1 percent loss on Monday after a record surge on Friday when news of the plan emerged and several countries instituted short selling bans.Banks took most points off the index, with UBS <UBSN.VX> falling 7.9 percent and Royal Bank of Scotland <RBS.L> losing 5.9 percent.
Miners also fell sharply, tracking metal prices. Anglo American <AAL.L> was the heaviest-weighted individual loser on the index, falling 8.2 percent, while Rio Tinto <RIO.L> lost 5.1 percent.
Federal Reserve Chairman Ben Bernanke and Treasury Secretary Henry Paulson stressed to Congress the dire consequences of failing to move quickly on the plan for the government to buy up hundreds of billions of dollars of tainted mortgage-related securities.
"Paulson and Bernanke will do their utmost to get a sense of urgency into Congress, but this is particularly sensitive because of the election season, and politicians will take all the room they can have to make populist changes," said Emiel van den Heiligenberg, head of asset allocation at Fortis Investments.
"We would expect the plan to be accepted, perhaps in a slightly amended form, but stay cautious on markets because of the recession and the impact on earnings. That's something that needs more time to work itself out," he said.
Drugmaker Novartis <NOVN.VX> jumped nearly 3 percent after a Credit Suisse upgrade, while chipmaker Infineon <IFXGn.DE> rose 1.3 percent on renewed market talk that it has found a buyer for its memory chip unit Qimonda <QI.N>.
Infineon said it did not comment on rumours and reiterated its position that it wanted to reduce its stake to below 50 percent by the next annual shareholder meeting in 2009.
BIG LOSS
Across Europe, Britain's FTSE 100 <
> lost 1.9 percent, France's CAC < > fell 2 percent and Germany's DAX < > dipped 0.6 percent, outperforming as defensive utilities E.ON <EONGn.DE> and RWE <RWEG.DE> gained 1.4 and 1.7 percent respectively.Energy shares were losers as oil eased after a record surge the previous session. BP <BP.L>, Royal Dutch Shell <RDSa.L> and Total <TOTF.PA> eased 0.1-1.8 percent as oil <CLc1> fell 2.3 percent.
The FTSEurofirst 300 has fallen more than 26 percent this year after five years of gains, punctured by a credit crisis that has driven banks to huge losses and slowed the economy.
Credit Suisse said in a European equity research note that the U.S. authorities' action "has probably called time on the bear market but has not yet signalled a bull market."
"Top-down, the immediate growth outlook is still impeded by a need for the corporate and personal sector to de-lever, suggesting that bottom-up, equity earnings estimates have further to fall," Credit Suisse said.
Van den Heiligenberg said that markets still had plenty to digest.
"We wouldn't advise anyone to buy a bounce -- if you have any ammunition, sell the bounce," he said. (Additional reporting by Peter Starck in Frankfurt; Editing by Jon Loades-Carter)
