PRAGUE, Feb 20 (Reuters) - Concerns that the European Union's eastern members could see a broader economic crisis rose this week as ratings agencies and mainstream western media warned over plummeting growth and financial imbalances.
The region's economists and governments have cut growth outlooks sharply in recent months, with the worst off economy, Latvia, set to contract by double digits this year and the best off, Poland, hoping to eke out an expansion of just over 1 pct.
The gloom has sparked a selloff of Czech, Hungarian, Polish and Romanian assets, cutting up to a third off their currencies, and also caused some contraction in financing from the big Western-owned banks that are the region's main lenders.
But economists also say the dire warnings may be overplayed, and stress the importance of differentiating between countries -- mainly in the Baltics and the Balkans, plus Hungary which has had an IMF rescue -- with big external exposure and those that will be hit but should avoid balance of payments or banking crises.
They say Poland and the Czech Republic, which have kept relatively low external and budget deficits, have the best chance of riding out the storm although the chances of any country returning to 5-percent economic growth in the next few years are low. Policymakers also stress that EU membership differentiates the region from Russia and Ukraine.
Following are good, middle and worst-case scenarios for how the crisis and policy response could play out.
GOOD CASE
In the best-case scenario, banks manage to contain rising default risks and continue lending. Companies manage to pay debt, stay afloat and households tighten their belts but stave off mass problems with repaying foreign-currency mortgages or other debt.
Currencies stabilise in the next few weeks and European Union policymakers and the International Monetary Fund take steps to shore up the worst hit economies and, if necessary, back big foreign banks.
Either way, analysts say more funds will be needed to shore up the banking sector by raising liquidity and making other loan facilities available, boosting confidence and telling western banks they must keep lending both in home countries and abroad. Most say that would best be a unified response.
"It would have to be very soon, or we'd flip into the negative scenarios very quickly," said Koon Chow, strategist at Barclay's Capital.
There would be capital injections into banks, swap deals, and other liquidity measures from the European Central Bank and the European Bank for Reconstruction and Development -- some of which have already been floated.
It would require broad, EU-wide political backing. There would be no outright bailouts but if a bank did have trouble, there would be quick action to shore it up.
The measures would give time for countries to adjust, possibly including consumers and firms switching to domestic-currency loans from euro and Swiss franc loans, and possibly for governments to create new bankruptcy laws to allow for an orderly unwinding of bad loans and assets.
MIDDLE BAND
In the middle scenario, the EU and its eastern newcomers would avoid a serious crisis but constrained lending from the West and wide imbalances would force the EU and International Monetary Fund to extend loans to several countries.
"Forget the total meltdown. It's going to be a muddle-through situation, with the length of the crisis depending on the timing of the policy reaction," said Simon Quijano-Evans, CEE economist with C.A. Cheuvreux.
Economies would slow more sharply than currently expected, current account gaps would shrink. Currencies could fall further, forcing central banks to defend their currencies with high interest rates and other measures, exacerbating the slowdown. Western-owned parent banks would stay in the region -- seeing it as more profitable to ride out the storm -- but could reduce balance sheets in the countries seen as most risky.
Central banks would inject liquidity and possibly reduce reserve requirements to free up more funds for lending, while slowly weaning borrowers off loans in foreign exchange.
Governments would have to pay higher yields, and euro zone ambitions could move to the sidelines while governments ramp up debt and budget deficits to pay for more spending and keep their economies sputtering along.
WORST CASE
Most analysts expect policymakers to step in before the region gets anywhere near this scenario.
In the worst case, debt-refinancing grinds to a halt, defaults rise sharply, causing companies to go bankrupt and households to fail to cover mortgages, thanks in part to further currency falls. Banks hit serious difficulties, creating knock on effects for parent institutions or vice-versa. Countries are unable to agree on a coordinated response, and take a range of independent action which fails to stave off further trouble.
Foreign parent banks would not roll over debt for their subsidiaries in the region and credit growth would be negative, hurting households and companies, and exacerbating the economic slowdown and a selloff of regional assets.
Loan default risk would rise, hitting bank capital and increasing the risk of failures. Some banks in the EU would have to be nationalised and their governments would ask them to use capital injections only for domestic lending.
That could trigger failures or bank runs on subsidiary banks in the most exposed economies and could cause EU newcomer governments, already struggling with financing, to have to seek ways to save the banks or let them fail. The EU and the IMF would mop up the damage only after the crisis starts.
Currencies would fall, and those countries with currency boards might have to abandon their pegs to the euro due to the high cost of bailouts.
"To assume that a group of states with 600 million people goes bankrupt because it can't refinance its debt anywhere in the world no matter at what price -- that to me is an exaggeration," said Matthias Siller, Fund Manager Emerging Markets, Barings Asset Management.
"If it's not possible to refinance emerging Europe's short-term debt then we'll have a global problem that will end in a global catastrophe. If that were to happen, Italy is next in line and you'll find no credit anymore, anywhere." (Reporting by Michael Winfrey and Boris Groendahl; editing by David Stamp)
