* EBRD cuts emerging Europe 2010, 2011 GDP forecasts
* Southeast Europe 2010, 2011 GDP forecasts cut
* Hungary/IMF standoff could hit regional economies, markets
(Adds details, background)
LONDON, July 22 (Reuters) - The European Bank for Reconstruction and Development (EBRD) on Thursday cut its 2010 and 2011 economic growth forecasts for emerging Europe, warning of greater uncertainty due to fiscal tightening measures across the euro zone.
It also said the suspension of the International Monetary Fund's talks with Hungary on its aid programme could affect markets and economies in the rest of the region.
The development bank cut its projected 2010 gross domestic product growth rate for emerging Europe to 3.5 percent from the 3.7 percent it predicted in May, and also lowered its 2011 forecast to 3.9 percent from 4 percent.
"Given the weakening outlook for the euro zone -- as fiscal austerity programmes are implemented and financial markets are likely to remain volatile -- the external environment is likely to be less benign than previously projected," the EBRD said.
Monetary tightening in China could also trigger a sharper-than-expected slowing of global growth, the bank said.
Credit growth in the region will stay weak as bank balance sheets remain under pressure and the cost of capital is expected to stay elevated, it said.
With the exception of Turkey, the outlook for southeastern Europe has weakened, the bank said, noting that the region was suffering from near zero or negative output growth as well as financial-market pressures due to worries over sovereign debt.
On average, the EBRD expects the economies of southeast Europe to shrink 1.5 percent, compared with its more optimistic projection in May of 0.3 percent growth.
The revision is sharper in 2011, with southeast Europe GDP expected to expand 1.2 percent, less than half the 2.9 percent growth rate seen in May.
Emerging Europe is recovering from its steepest recession since the collapse of communism in the region two decades ago, when the EBRD was set up to help former communist economies adjust to free markets.
HUNGARIAN CONCERNS
The EBRD said there was a growing disparity in the pace of recovery across the 29 economies where it operates.
It expects the recent stronger than projected economic growth in eastern Europe to fade in 2011.
Eastern European economies are seen expanding at an average of 3.9 percent next year instead of the 4.2 percent previously forecast.
The commodity-focused economies of Russia and Mongolia, however, are expected to continue to benefit from strong commodity prices.
Noting "poorly communicated" fiscal-policy statements by Hungary's new government in June, the EBRD warned that the country's revenue-raising plans, which include a bank levy, risked undermining its economic recovery.
"Measures announced in the financial sector, including a temporary levy on all financial institutions, risk derailing any recovery in credit, which would further set back the recovery in domestic demand," the EBRD said.
The breakdown of talks with the IMF over the continuation of Hungary's 20 billion euro multilateral financing package could also "cause additional volatility and dampen growth in the country and beyond", it added.
Hungarian Prime Minister Viktor Orban signalled on Thursday that he would not renew the country's safety net with the IMF and would row back on a commitment to cut the budget deficit to European Union-prescribed levels next year. [
