Is Greek government debt really 177% of GDP?

The triumph of the anti-austerity Syriza party in Greece’s general election has put back on the table the vexed question of what to do with Athens’ debt. Economists tend to disagree over how sustainable this burden really is: some point to the sheer size of the liabilities, saying Athens will never be able to pay them back. Others emphasise the favourable conditions which the Greek government has secured on official sector loans in two rounds of restructuring: these include heavily subsidised interest rates and a lengthening of the average maturity of the debt, which now stands at 16.5 years, double Italy’s or Germany’s.

One figure on which everyone tends to agree, however, is that Greece’s public debt is 177 per cent of gross domestic product, the highest level in the eurozone. Well, everyone but a private equity group and a number of accountants, who think the relevant figure could be as low as 68 per cent.
