Frankfurt - Central banks pumped more dollars into the banking market Wednesday, and the European Central Bank (ECB) said it would supply as much liquidity as was needed to stop the financial crisis.

As part of the central banks' joint infusion of dollars, which began earlier in Japan, the ECB stepped up its offer of overnight money from 30 billion dollars on Tuesday to 50 billion dollars Wednesday.

The British and Swiss central banks also dumped dollars into markets to relieve strains. Commercial banks have been reluctant to lend to one another money in the crisis.

ECB President Jean-Claude Trichet said in Frankfurt, "The ECB will support access by solvent banks to sufficient liquidity and the functioning of the money markets for as long as necessary."

But Trichet appeared to reject calls for the ECB governors to cut interest rates when they meet Thursday.

He said there was a danger of inflation in euro zone, and warned against increasing money supply, saying that supplying banks with liquidity was not the same thing.

Meanwhile Germany's government rejected calls for the European Union to mount a US-style bail-out of banks.

"I don't know anybody who is seriously proposing such a European model," said Thomas Steg, a spokesman for the German government. He said it was better for nations to intervene case by case in their own national interest.

Germany posted a 35-billion-euro guarantee this week for Hypo Real Estate, the first German bank to stumble in the latest crisis.

France is to host talks with G8 members Germany, Britain and Italy this Saturday about the turmoil, but Steg said it would be wrong to call it a "crisis summit."

The German spokesman said the agenda was still being discussed. Chancellor Angela Merkel of Germany would attend if the Paris meeting took place. (dpa)
