Or, as Krugman puts it, Eurodämmerung:

Some of us have been talking it over, and here’s what we think the end game looks like:

1. Greek euro exit, very possibly next month.

...

4b. End of the euro.

And we’re talking about months, not years, for this to play out.

Good thing I only have about €15 in cash. Though I do have some escudos and pesetas somewhere...
