Dislikedits almost as saying united states will beak up because you have some states which lose money and others which cover for it....no way it will happen unless some kind of civil war breaks out......
one of the best option in my view would be.....
quetly get a loan of saaay 100bn from EU IMF or even Russia for that matter, create severe panic in the market by spreading the news that everything is going to shits and rumoured haircut going to be 40-50%, bond prices drop they use the loan to buy the bonds at very nice discount (20-30%) then tell...Ignored
A few points here, there is no EU IMF, Russia does not have that kind of money and Greece has no long term debt, it is all short term unlike the UK for example. Also the total debt of Greece exceeds their annual GDP, unlike again UK where it is only 61%. You are missing the sentiment issue, this is no longer a technical macro economic exersise. No investment bank will underwrite a Greek debt issue now. You just can't trust their numbers, they change by the week.
