DAVOS, Switzerland (AP) — Is the euro crisis over? A leading U.S. economist says not by a long shot.
Even as the head of the European Central Bank talked Friday of "positive contagion" in the markets and predicted an economic recovery for the recession-hit eurozone later this year, economist Barry Eichengreen warned that the debt crisis that has shaken Europe to its core could easily erupt again this year unless European leaders move faster to solve their problems.
While European governments and markets have been breathing easier in recent months after years of turmoil, it's no time for complacency, said Eichengreen, who has chronicled the Great Depression and explored the consequences of a breakup of the euro currency used by 17 nations.
"Nothing has been resolved in the eurozone, where markets have swung from undue pessimism to undue optimism," Eichengreen told The Associated Press in an interview at the World Economic Forum in Davos, Switzerland. "They said all the right things last year ... and they've been backtracking ever since."
He warns that the crisis over too much debt burdening governments and banks in the 17-country currency group "is going to heat up again in 2013."
He urged eurozone leaders follow up on its proposals to steady its banking system and keep failed banks from adding to government debt through expensive bailouts.
European leaders in Davos this week are seeking to reassure investors and corporate leaders that the continent is on the mend after its punishing debt crises.
European Central Bank chief Mario Draghi on Friday forecast a recovery in the eurozone economy in the second half of the year, and spoke of "a new restored sense of relative tranquility" and "positive contagion on the financial markets."
But he acknowledged "we don't see this being transmitted into the real economy yet."
Draghi said governments need to move ahead with structural reforms to make their economies grow faster, which will help reduce government debt.
Heavily indebted countries such as Spain and Italy faced alarmingly high borrowing costs on bond markets last year, as investors wondered whether they would be able to keep paying their debts. Those bond market rates fell after key steps by European leaders. One was the European Central Bank's offer to purchase bonds issued by indebted countries if they promise to reduce their deficits. Another was a proposal to set up a so-called banking union that would keep failed banks from bankrupting any one country by transferring the supervision of bank behavior and finances to a single, central EU supervisor at the ECB.
Europe, meanwhile, is in a recession that is putting added pressure on government finances.
"Europeans will be shocked out of their complacency, I think, soon enough," Eichengreen said. "There will be a relapse to the greater volatility of the first half of last year."
"None of the underlying problems have been solved. There is no economic growth in Europe. Germany itself is on the verge of recession. The banking union doesn't exist. There's less consensus on completing it than we thought last year, so the markets are going to lose patience at some point and the crisis will be back. "
Eichengreen, a professor at the University of California, Berkeley, studied the possibility of a eurozone breakup long before the crisis that started in late 2009 forced other people to consider what was once unthinkable. He concluded that leaving the euro would be disastrously expensive and cause widespread chaos for any country that tries it.
Political leaders are aware of those high costs, which means a country such as debt-strapped Greece leaving the eurozone "is off the table for the moment," he said.
Concerns about Europe's economic future — and the threat that Britain could one day pull out of the European Union, whose 27 members together make up the world's largest economy — clouded this year's gathering in the Swiss Alpine resort of Davos.
The forum pulls together corporate and political leaders who strike business deals, strategize about world problems and attend lavish parties — and comes under regular criticism from activists and workers who say the elite event is disconnected from the world's economic realities.
Activists at Davos took over a Shell station Friday to protest drilling for oil in the Arctic.
