So nobody knows what is going on in Greece. Tspiras seems willing, as he has done all along, to compromise. Meanwhile, Dr Schaubel, which is German for “hell, no”, seems to as willing to be as uncompromising as possible, in between lecturing the ECB
If Greece does GREXIT, which is not certain, this will result in a depreciation of the currency by up to 50% some reckon. And here is the rub. Greece is critically dependent on certain things which will get expensive, while its exports (in trade) are not that large nor perhaps that amenable to rapid rampup in the face of increased demand concomitant on falling prices, or are indeed priced in non Euro currencies anyhow. While tourism and services help, Greece runs a massive CA deficit. The logic of GREXIT is that somehow not only will debt disappear (only if they default in tandem will that happen) but that exports will boom. Well, maybe.
This whole thing has been grossly mishandled, and while the Greeks have a bunch of blame, the TROIKA must take the lions share. If they are, as Lagarde said, the “adults” then its time to start behaving like it.
