 BERLIN (Reuters) - The costs to a country of leaving the 
euro zone  would be so high that many analysts think the bloc will do everything  in its power to prevent an exit, even if that requires the richest  members to keep bailing out weak states.
  German magazine Spiegel  reported on Friday that the Greek government had raised the possibility  of breaking away from the 12-year-old euro area and reintroducing its  own currency in talks with the European Commission and other member  states in recent days.
The report  was vigorously denied by the Greek finance ministry and officials from  other member states. Sources did confirm that a small group of euro zone  finance ministers were meeting in Luxembourg on Friday to discuss 
Greece and other pressing matters.
Leaving  the currency union would carry huge economic, social, reputational and  strategic costs for Greece or any other country. Greece would have to  hive off its bank deposits from the rest of the euro zone banking system  as it introduced a new currency, risking a run on its banks and huge  disruption for its companies.
Banks across Europe would face losses on their Greek debt.
For  the bloc as a whole, it would represent a humiliating setback because  the common currency is broadly viewed as the culmination of half a  century of European integration.
"To  me the euro zone is a one-way street," said Gilles Moec, senior  European economist at Deutsche Bank. "A breakup would have catastrophic  consequences for the country that left. It would precipitate a run on  the banks. I can't see how you do it in an orderly way."
Speculation  about a possible euro zone breakup reached fever pitch in November of  last year, but predictions that the bloc will fracture have come mainly  from Anglo-Saxon skeptics.
Last  summer, British economist Christopher Smallwood of consultants Capital  Economics produced a 20-page paper entitled "Why the euro zone needs to  break up" and U.S. economist Nouriel Roubini, nicknamed Dr. Doom, has  said euro members will be forced to abandon the shared currency.
DEBT RESTRUCTURING RISK
Greece  has struggled to meet the fiscal targets set out for it as part of its  110 billion euro ($160 billion) bailout from the European Union and  International Monetary Fund.
Over  the past month, markets have priced in the sort of default risk that was  once unthinkable for a euro zone state and expectations have risen that  Greece will have to restructure its 327 billion euro debt load while  other countries will have to provide more aid.
Political  opposition in northern Europe to giving Greece more money and rising  anger within the country at the tough austerity measures the government  has put in place have created a dangerous new dynamic that has convinced  more experts an exit may conceivably happen, although probably not for  years.
By reintroducing the  drachma, the argument goes, Greece could sharply devalue its currency  against the euro and keep official interest rates ultra-low, regain  competitiveness, and tackle its debt problem without the political and  social upheaval associated with years of austerity-fueled recession.
"I'm  not suggesting that these stories are right," said Jonathan Loynes,  chief European economist at Capital Economics. "But we have said that we  think it's quite likely that there will be some change to the  membership of the euro area over the next four to five years and that  one possible form will be the exit of a small economy like Greece.
"I don't think the idea is implausible at all."
But  U.S. economist Barry Eichengreen, who authored a 2007 paper arguing  that the single currency could not be undone, reaffirmed that belief  last year as the Greek crisis deepened.
"Adopting the euro is effectively irreversible," he wrote in an article on the economics website Vox.
"Leaving  would require lengthy preparations, which, given the anticipated  devaluation, would trigger the mother of all financial crises," said  Eichengreen, a professor at the University of California, Berkeley.
LEGAL NIGHTMARE
There  is no legal procedure for leaving the euro zone and some economists  argue that treaty changes would have to take place before an exit could  happen.
"You would have to make it  legal in order to leave," said Moec of Deutsche Bank. "You would  probably have years of litigation on all the debt held outside the  country."
Trade flows would  probably be severely disrupted. Business costs would become  unpredictable, inhibiting investment. Labour unrest and social strife  would likely result as citizens faced mass unemployment, inflation and  brutal public spending cuts.
That would far outweigh any potential boost to exports or tourism revenues from a devaluation.
"But  what if the bank runs and financial crisis happen anyway?" Nobel  prize-winning economist Paul Krugman asked on his blog last November.
An  exit that is neither planned nor chosen but imposed by irresistible  market forces would dramatically reduce the marginal cost of leaving the  euro, Krugman contended.
But that economic logic may underestimate the political will that has driven European monetary union since its inception.
