"Within the class of high- and middle-income countries, only three restructuring cases were harsher on private creditors: Iraq in 2006 (91%), Argentina in 2005 (76%) and Serbia and Montenegro in 2004 (71%). There are a number of cases of highly indebted poor countries, such as Yemen, Bolivia, and Guyana, that imposed higher losses on their private creditors. However, the Greek haircut exceeds those imposed in the Brady deals of the 1990s (the highest was Peru 1997, with 64 per cent), and it is also higher than Russia’s coercive 2000 exchange (51%)....the 2012 Greek exchange was exceptional in size, exceeding the next largest sovereign credit event in modern history, which to our knowledge wasRussia’s default on 1.7 billion British pounds in 1918, equivalent to just under 100 billion in 2011 Euros. The Greek exchange also easily surpasses the German default of 1932-33, the largest depression-era default on foreign bonds, comprising 2.2bn US$ at the time, or approximately 26 billion in 2011 Euros."
