Government debt stabilized at 90 percent of economic output in the 17 nations sharing the euro in the third quarter, barely changed from 89.9 percent in the second, the EU's statistics office Eurostat said on Wednesday.
With public debt expected to peak at 94.5 percent in all of 2013, according to European Commission forecasts, the stabilization is another sign the euro zone has a chance to emerge from a banking and debt crisis that nearly destroyed it.
But while the Commission expects debt to start falling from 2014, it is still above the 90 percent level that economists consider damaging for growth.
It is also well above the EU's limits for a healthy economy and will take decades to pay down.
Europe's debts soared from the EU-mandated limits of 60 percent of gross domestic product following the introduction of the euro in 1999, as countries from Spain to Ireland indulged in massive borrowing at very low rates of interest.
A divide now exists between France and Germany on the one hand, where debt fell slightly in the third quarter from the second, and the economies of Ireland, Greece, Portugal, Spain and Italy, whose debt-to-GDP ratio rose in the July-September period.
Debt in Ireland, where a burst real estate bubble forced the country into an international bailout, reached 117 percent of economic output in the quarter, while the number was 127 percent in Italy. Spain saw its burden tick up to 77 percent of GDP, and the Commission sees it reaching 97 percent in 2014.
Greece's debt rose to 153 percent of GDP in the quarter and will reach 189 percent in 2014, although a deal struck by euro zone finance ministers and the International Monetary Fund in November aims to take it down to 124 percent by 2020.
Italy's Economy Minister Vittorio Grilli admitted as much in Brussels this week, saying the country's economic recovery from 2014 would be "inadequate".
Compared to the United States and Japan, the euro zone looks better off, with economists seeing U.S. debt at 115 percent of GDP by 2016 and the Japanese burden climbing to an eye-watering 250 percent by then.
But the European Commission, which has powers to police countries' debts and wants to avoid the borrowing binges of the past, says that is no excuse, and its top economic official warned earlier this month of the costs to growth.
"When public debt levels rise above 90 percent they tend to have a negative impact on economic dynamism, which translates into low growth for many years," EU Economic and Monetary Affairs Commissioner Olli Rehn told diplomats in a speech. "That's why consistent fiscal consolidation remains necessary."
