The question of debt forgiveness, or a "haircut," can be revisited after the current bailout program will be successfully concluded and the government in Athens no longer takes on new debt, Merkel said in an interview with the German Sunday tabloid Bild am Sonntag.
Merkel's government had previously ruled out forgiving debt, arguing that Greece must implement the agreed-upon austerity measures and structural reforms in return for its bailout loans. But the International Monetary Fund and many economists say eurozone nations must also forgive Greece some of its debt to allow the country to overcome its debt crisis.
Greece is trapped by an unsustainable debt level — forecast to reach 190 per cent of the country's economic output next year — which forces it to drastically slash its budget. That, in turn, deepens the country's recession, and makes Greece's debt load rise even more in relation to its gross domestic product.
When asked about a haircut on Greece's debt as a way out of the situation, Merkel told the newspaper "when Greece one day again manages with its revenue, without taking on new debt, then we have to look anew at the situation and reevaluate."
"That won't be before 2014-2015 if all goes as planned," she added.
Greece has promised its international creditors to achieve a budget surplus of 4.5 per cent of its GDP by 2016, which would enable the country to start paying back part of its debt.
Greece, which is about to enter its sixth consecutive year of a deep recession that has pushed unemployment up to 25 per cent, is being kept afloat with rescue loans from its European partners and the International Monetary Fund.
German opposition leaders and analysts have accused Merkel of playing down the need to write off some of Greece's debt held by eurozone governments before national elections in Germany next year for fear of voter retribution.
Merkel did not directly address that charge, noting only that Greece's current bailout programs runs through 2014, hinting that she sees no need for yet new measures before then.
The hawkish head of Germany's central bank, Jens Weidmann, last month said that Greece will eventually need a haircut, but it should only be granted after a prolonged period of budgets cuts and labour reforms there.
Earlier this year, Greece reached a deal with its private creditors to wipe some €100 billion ($130 billion) off its national debt, or about half of the country's GDP.
Still, a second haircut on Greece's debt from the eurozone rescue loans might be necessary. Analysts say such a haircut could cost Germany, the main contributor to the bailouts, up to €17 billion ($22 billion) — more than 5 per cent of Berlin's annual budget.
Merkel's comments came only two days after Germany's parliament voted in favour of granting Greece more lenient terms on its bailout program, clearing a necessary hurdle for disbursing a €44 billion ($57 billion) rescue loan payment in December that Athens needs to avoid bankruptcy.
