Perhaps Greece - a country with a debt to GDP already approaching 150 percent and set to move even higher - avoids a debt restructuring. Perhaps not. 

What are the possible scenarios if Greece cannot return to the capital markets to refinance this gargantuan debt stock once its EU/IMF bailout package expires in two years time? What would a Greek debt restructuring look like after mid-2013? And (sharp intake of breath here) what would happen if such a debt restructuring were undertaken before that point?
