LONDON/WASHINGTON, Feb 27 (Reuters) - Three development banks launched a 24.5 billion euro loan programme on Friday for central and Eastern European banks and firms, but officials said the region could need more than 10 times that to avoid a crisis.
The announcement came ahead of a European Union summit on Sunday at which leaders hope to bridge differences hindering unified action on the financial crisis.
The World Bank, European Bank for Reconstruction and Development (EBRD) and European Investment Bank (EIB) said the two-year plan will provide quick, large-scale financing to banks and ensure smaller companies would not be shut off from capital.
That gave a lift to the region's battered currencies, but they soon retreated as markets judged there was not that much new money in the deal compared to the funds already announced and the kind of financing needed to keep growth going.
"(It) sounds like a lot of money, but when (commercial) banks have lent Eastern Europe about 1.7 trillion dollars, 25 billion is peanuts," said Nigel Rendell, emerging markets strategist at Royal Bank of Canada in London.
"Ultimately we will have to get a much bigger package and a coordinated response from the IMF, the European Union and maybe the G7."
Concerns centre around some countries' reliance on external borrowing and that the region's largely foreign-owned banks could shut off lending due to the global credit crunch and their need for money at home.
The package is the development banks' contribution to EU efforts to help the region, which has seen some of the bloc's newer members seek emergency funding from the International Monetary Fund.
EBRD President Thomas Mirow told French newspaper Le Figaro that eastern European banks could need some $150 billion in recapitalisation and $200 billion in refinancing to stave off the risk of a banking failure in the region. [
]"The institutions are working together to find practical, efficient and timely solutions to the crisis in eastern Europe," Mirow said earlier in a statement.
"The deep integration of the banking sector across Europe has proven to be one of the crucial drivers in forging the economic unity of the region," he said.
Ratings agency Standard & Poor's said the package was good news but added it would have no direct sovereign ratings impacts, and warned of persistent risks in the region.
EU BILLIONS
Some member states are seeking to discuss a proposal for a "platform" to help eastern European economies and their banks at the weekend EU summit.
"You can reasonably infer that this (package) could be the first part of a more global answer from the European Union," Philippe Maystadt, president of the European Investment Bank, the EU's long-term lending bank, told Reuters in an interview after Friday's loan package was announced. [
]Hungary's Prime Minister Ference Gyurcsany told Bloomberg on Friday he would present a plan to arrange an 180 billion euro ($228.2 billion) package for eastern Europe. [
]That was up from an earlier figure of 100 billion euros.
The IMF welcomed the development banks announcement, and said it would continue to support regional economies on a macroeconomic level. [
]A massive expansion of international banks into eastern Europe has made the region's banking system vulnerable to credit strains that arose from the U.S.-led housing collapse that spread into Western Europe.
Austrian banks, which have been particularly exposed to the region, could withstand worst-case loss scenarios by using existing capital cushions and drawing on the government's bank rescue package, the Austrian central bank said. [

WHAT'S IN IT?
Under the development bank plan, the EBRD will provide up to 6 billion euros this year and next to the region's financial sector and will include trade finance through banks.
The EIB said it will lend 11 billion euros to businesses in central, eastern and southern Europe, of which 5.7 billion euros is ready to be disbursed, and a further 2.8 billion euros should be approved by the end of April.
The Washington-based World Bank said it intends to propose lending and political risk guarantees of up to 7.5 billion euros for banks, infrastructure projects and trade financing.
The three banks said they will mobilise other resources for the region through their lending and guarantees, and work with Western parent banks that have promised support for their struggling subsidiaries in the region.
The lenders said their aid will be in the form of equity and debt finance, credit lines and political risk guarantees.
They welcomed the support of the IMF, which has approved $50 billion in emergency packages for Iceland, Hungary, Latvia, Ukraine, Serbia and Belarus in recent months.
