Yet it is hard to believe that Greece can avoid debt restructuring. First, assume, for the moment, that all goes to plan. Assume, too, that Greece's average interest on long-term debt turns out to be as low as 5 per cent. The country must then run a primary surplus of 4.5 per cent of GDP, with revenue equal to 7.5 per cent of GDP devoted to interest payments. Will the Greek public bear that burden year after weary year? Second, even the IMF's new forecasts look optimistic to me. Given the huge fiscal retrenchment now planned and the absence of exchange rate or monetary policy offsets, Greece is likely to find itself in a prolonged slump.
