It’s being discussed in the comments already but it’s worth giving German Finance Minister Wolfgang Schauble’s letter to the ECB, IMF and Ecofin ministers its own thread. The key proposal:
This means that any agreement on 20 June has to include a clear mandate — given to Greece possibly together with the IMF — to initiate the process of involving holders of Greek bonds. this process has to lead to a quantified and substantial contribution of bondholders to the support effort, beyond a pure Vienna initiative approach. Such a result can best be reached through a bond swap leading to a prolongation of the outstanding Greek sovereign bonds by seven years, at the same time giving Greece the necessary time to fully implement the necessary reforms and regain market confidence.
Just to be parochial about this for a minute, this raises an interesting question. If this approach was implemented successfully and did not trigger a financial crisis (I know some disagree — this is a hypothetical question) what are the chances that a similar restructuring would not be part of any potential second EU-IMF deal for Ireland?
