Red Jahncke posits that it should be Germany, and not Greece, that should exit the euro. The stance is controversial, but here is his logic:
A Greek exit from the currency union would make the situation even worse. There is no mechanism to decide, or deal with, whichever nation might be next, and even that presumes that exits could be managed. The more terrifying prospect is that the other afflicted countries might exit in an uncontrollable panic, complete with bank runs, failures and general disarray. The accompanying repudiation of hundreds of billions of euros in debt would overstrain the European financial system, even Germany’s. The global economy would be paralyzed as everyone wondered which domino would be next to fall.
What, then, might a German exit do? With integration and multiple restructurings so unlikely and withdrawal of the weak members so fraught, it might actually be the best of all available options.
A single, powerful nation would have the best shot at executing a relatively swift exit that would be over before anyone could panic. No agonizing over who exits and who doesn’t. Stripped of its German export powerhouse, the euro would depreciate sharply, but would not become a virtually worthless currency, as, for example, any re-issued Greek drachma surely would. With the euro devalued, a Greek exit and devaluation would be relatively pointless. So, no contagion or bank runs. With new exchange rates making all the non-euro financial havens prohibitively expensive, and with the threat of forced conversion into devalued national currencies removed, depositors in southern Europe would lose their impetus to run.
Germany’s exit would provide immediate benefits to all the remaining euro-area nations. The currency depreciation would radically improve their trade competitiveness — exactly what many observers have said the weaker nations in the south need most. The euro area’s balance of payments would improve, providing sorely needed funds to service its external debt. The benefits would accrue to the euro area as a whole, as opposed to serial exits at the weak end of the spectrum, which would crush one weak nation after another, with each exit increasing pressure on the next candidate.
