Now if they end up writing off the Greek debt, will other countries in the EU want a "Greek deal"...
This is one of the problems with the idea of a write-off of Greek debt.
The other problem is that it is absolutely illegal under the Treaties. Now in fairness the EU has a very casual approach to law, and what everyone who reads the Treaties thinks is illegal and what really is illegal may be different. QE is illegal under the Treaties but now we have massive QE and it isn't illegal under the Treaties. If the EU nations wanted they could find a way of making this illegal activity legal.
Both of these problems are aspects of the idea of debt mutualisation within a single sovereign state. This was indeed envisaged by the architects of the euro - indeed the primary function of the euro was to create the "beneficial crisis" that would force the creation of a single sovereign state. France is indicating that this might well be the direction of travel, and Spain and Italy are likely to be sympathetic. Nothing can happen quickly (and anything that happens will be too late for Greece) but it is a possibility nonetheless. The big nation set against it is Germany.
A few weeks ago we all thought that the Greek crisis had reached a peak where either there would be a solution or Greece would leave the euro. The deal inflicted on Greece did appear to be a solution within the concept of a debt colony. However this is unravelling. The UN has suggested it may be a crime in international law. The IMF is saying it won't work and refusing to take part without debt relief. Greece is frustrating the process as much as any debt colony can. I think we must very soon be back to crisis.
There are solutions but they are all solutions that people say are impossible. Which impossible solution do we want:
1) Greece becomes entrenched as a debt colony, a practice illegal in international law and one which may even constitute a crime against humanity.
2) There is a proper write-down of Greek debts, as required to satisfy the IMF. This has to be a write-down (not a deferral), it has to be of debts owed to the ECB and EZ nations and banks, and it has to be huge, perhaps 50%. In effect this is debt mutualisation within the Eurozone, and if it is done once the markets will expect and require it subsequently.
3) Greece defaults on 100% of its debt and reintroduces the drachma. This would be difficult for Greece. It would be the end of the euro. It would create a global depression.
4) Germany leaves the euro and the euro is unwound in an orderly fashion.
Option 1 is horrific, yet this is what we are bungling towards. 2 is a bit better though it's just kicking the can - the problem will be back either in Greece or elsewhere and will be even worse. 3 is better still - but realise I'm saying a global depression is better than two other options. 4 is the only good option. Does Germany have the guts to do the right thing? Twice in the last century Germany has destroyed Europe. Now it has the chance to save Europe.
