LONDON, Oct 15 (Reuters) - Emerging European economies will likely grow an average 2.5 percent next year as a "fragile and patchy" recovery takes hold but the risk of a banking collapse remains high in some countries, the European Bank for Reconstruction and Development (EBRD) said on Thursday.
Senior economists at the development bank said the likelihood of a region-wide meltdown from any bank failure was low but stressed economies need to reform a growth model that has left them over-reliant on foreign capital.
"Foreign banks contributed to higher debt levels (in the region) and had some role in fuelling credit bubbles. They also have played a role in increasing foreign exchange exposure which has turned out to be a major vulnerability during the crisis," EBRD Chief Economist Erik Berglof told a media briefing.
"We need to find ways of addressing the failures of this model without fundamentally changing it...There are aspects of it we need to control."
The London-based lender revised its 2009 forecast for the region as a whole to a 6.3 percent contraction, steeper than the 5.2 percent decline previously forecast, but said positive third-quarter signs suggested the downturn was bottoming out in some economies.
The EBRD said its current 2010 growth forecast, up from its previous 1.5 percent estimate, reflects the deeper-than-expected downturn in the first half of 2009 rather than a vigorous recovery in 2010.
The forecasts were previously revised in May, the second time after a January adjustment. In November, it predicted a three percent 2009 economic expansion for the region.
"There is a tendency to equate 'normal' growth with the boom phase of 2006-2007 but I don't think we will return to that for a long time, if ever. And I don't think we should as that was unsustainable," said Jeromin Zettelmeyer, Director for Policy Studies at the development bank told Reuters.
BANK RISKS
Set up at the end of the Cold War to help former communist economies adjust to free markets, the EBRD has come under criticism from some of its 60-odd country shareholders for failing to warn eastern Europe and Central Asia about the dangers of overexposure to foreign borrowing.
But the bank said it remained concerned that reduced levels of Western-bank lending, in addition to a weakened export sector, would constrain growth in its 29 countries of operation.
Rising non-performing loans, underreported in some countries posed a particular threat. The pace of economic recovery in Russia and Kazakhstan, in particular, could be affected by their weak banking systems, the EBRD said.
"The risk that individual banking systems (in the region) could go down remains high as NPLs (non-performing loans) test the ability of institutions," Zettelmeyer said, highlighting Ukraine as an example of a country where bad debt is under-reported.
But contagion risk arising from any banking failure had receded with the overall stabilisation of the global financial system, he said.
The EBRD warned the region would face the social costs of its economic crisis in earnest next year, when corporate bankruptcies and unemployment will continue to rise.
Differences in gross domestic product (GDP) performance of countries in the region will also be stark next year, with the currency pegs adopted by Bulgaria, Latvia and Lithuania likely slowing the recovery for these economies, the EBRD said.
The bank said Russia's economy would shrink 8.5 percent in 2009 before rebounding 3.1 percent next year.
Countries that have sound banking systems such as Albania, Poland, Slovakia and Slovenia are likely to enjoy faster 2010 GDP growth of 2-5 percent.
The EBRD revised down its 2010 GDP forecast for Hungary to a 0.9-percent decline, saying slower growth was a result of a continued credit crunch and necessary fiscal adjustments. (Reporting by Sebastian Tong and Sujata Rao)
