Government bonds were long considered a safe investment that offered the potential for high returns. However, after Argentina announced in 2002 that it would no longer service its bond debt and after Greece restructured its sovereign debt in March and December 2012, the question arises as to what investors can do to avoid the significant losses of capital (up to 70% in case of Argentina and over 80% in case of Greece) which almost always accompany sovereign debt restructurings.
