Is the eurozone crisis over? The answer is: “yes and no”. Yes, risks of an immediate crisis are reduced. But no, the currency’s survival is not certain. So long as this is true, the possibility of renewed stress remains.

The best indicator of revived confidence is the decline in interest-rate spreads between sovereign bonds of vulnerable countries and German Bunds. Irish spreads, for example, were just 205 basis points on Monday, down from 1,125 points in July 2011.
