So what impact on the European economy will this have. I imagine this will have an impact on Swiss tourism due to the higher prices in Switzerland, but does this destabilize the Euro in general?
It impowerish some people (as example many in Poland have taken loans in Swiss Francs, because the strong Polish Zloty versus the Euro made this a good deal, it's no more) who have borrowed money in Swiss Francs, but for the Euro it means very little, yes it makes the Euro slightly weaker, but it's really by a small margin, and honestly the Euro is too strong right now. This would have been a problem or a good thing if Switzerland had been 10 times bigger.
