What do you believe/know/speculate about the future of Greece and especially the Euro?(I think a lot about this because I do not want to found a startup in a potential european inflation.)
Of course that says nothing about the timing....
The fiscal policies of Greece are unsustainable. Ditto for some of the PIIGS (Portugal, Italy, Ireland, Greece, Spain). A bailout without an austerity program will only delay the end ... that the latter looks somewhere between unsustainable to a non-starter.
A bailout would be very bad for the Eurozone, since it will increase the moral hazard for the rest of the PIIGS (well, maybe not Ireland). A failure to bailout Greece (now or later) will likely put the rest of the PIIGS in dire straits as their sovereign debt is put into question.
Greece can't make its creditors take an implicit haircut by devaluation as long as it uses the Euro. In the long run it's hard to see it both keep the Euro and not give the creditors an explicit haircut, i.e. they won't get all their money back ... which will make the continued borrowing they need harder to impossible.
I don't see any prospect for a soft landing.
However as d2viant implies, there's a good change that any of the above problems can be managed. The world is a rather open place ... things you have to worry about more than an inflation (which will only happen, at least any time soon, if Greece goes of the Euro, and then only for Greece) are problems like currency export controls.
E.g. if you're in Greece, you might find it impossible to pay e.g. Amazon for AWS services, they might impose controls on your ability to remove money from the country. On the other hand, if you keep enough of a presence outside of Greece including payments going into your company and then out to AWS you might be able to pull it off.
It's all very iffy, we just don't know how the various governments in question will handle these problems. Be flexible, try to keep reserves for problem, avoid single points of failure WRT to individual countries. Also don't obsess on inflation, there's enough deleveraging going on or the potential of that continued deflation is very possible.
The measures demanded by the IMF & EU (which is necessary for political will & arguably 'right') will cause the economy of Greece to contract.
There has been much squabbling within the EU about how to structure a loan and the whole thing has been a mess given differences within the EU.
The stability of the Euro is certainly much on the minds of the Germans given their experiences with the mark and the loan can be challenged in the German supreme court if it undermines the Euro.
I frankly wouldn't worry about which way the Euro will go. Especially when compared to the problems other wealthy nations will face.
