VIENNA, Jan 19 (Reuters) - Private credit growth, the main fuel for emerging Europe's economic motors, has started to show up in "green shoots" including Poland, the Czech Republic and the Balkans, a senior EBRD official said on Tuesday.
But for a sustainable recovery from the financial crisis that hit the former Communist bloc hard, banks had to thoroughly clean up their balance sheets, said Piroska Nagy, a senior advisor at the European Bank for Reconstruction and Development.
Non-performing assets piled up in countries that had excessive credit booms before the crisis still burden balance sheets and hamper banks' ability to provide funding needed in the region to emerge from the crisis, she said.
"We do see credit recovery in several cases, in some cases we even see the return of fx lending to households," Nagy told Reuters in an interview on the sidelines of a conference.
"We do also see that credit returns where there had not been a massive boom beforehand, which points to the need to clean up balance sheets," said Nagy, who is advising the EBRD's Chief Economist Erik Berglof on issues including the banking sector.
"No crisis cleanup and recovery in the past 50 years has happened without balance sheet cleanup," Nagy said. "If you don't do it, you go the Japanese way. So there is not too much of a choice."
Nagy acknowledged that banks were right to start the cleanup slowly during the peak of the crisis, it seemed to put the entire banking system at risk.
"There was a good reason why the cleanup wasn't that fast in the systemic phase of the crisis because you really had to keep things together," she said. "But it has to happen now that the systemic phase is over."
GROWTH RETURNS
In August to November, private sector credit in the EBRD region grew by an annualised 4.2 percent on average, after a 3.8 percent contraction in the March to August period, Nagy said.
Credit growth in many countries correlated with the recovery from recession, Nagy said. The EBRD is currently in the process of revising its outlook for the region, with results due in a few weeks. Nagy declined to discuss the revision in detail.
"We see a correlation between (economic) growth and private sector credit growth returning," Nagy said.
"That underlines the point that this region really needs private sector credit because there is no fiscal space and there are no other sources of funding," she said.
Credit growth returned to some of eastern Europe's most important economies including Poland and the Czech Republic, both by an annualised 2.6 percent, in which countries credit had dropped before, she said.
Credit also expanded in Serbia, Bulgaria and even crisis-struck Ukraine, she said, while it continued to contract in the Baltics, Kazakhstan and Russia.
