Paul Krugman - OK, now it's for real. Quote:
OK, this is real: Greek banks closed, capital controls imposed. Grexit isn’t a hard stretch from here — the much feared mother of all bank runs has already happened, which means that the cost-benefit analysis starting from here is much more favorable to euro exit than it ever was before.
Clearly, though, some decisions now have to wait on the referendum.
I would vote no, for two reasons. First, much as the prospect of euro exit frightens everyone — me included — the troika is now effectively demanding that the policy regime of the past five years be continued indefinitely. Where is the hope in that? Maybe, just maybe, the willingness to leave will inspire a rethink, although probably not. But even so, devaluation couldn’t create that much more chaos than already exists, and would pave the way for eventual recovery, just as it has in many other times and places. Greece is not that different.
Second, the political implications of a yes vote would be deeply troubling. The troika clearly did a reverse Corleone — they made Tsipras an offer he can’t accept, and presumably did this knowingly. So the ultimatum was, in effect, a move to replace the Greek government. And even if you don’t like Syriza, that has to be disturbing for anyone who believes in European ideals.
