Just as only four short years ago it was All Subprime, All the Time, and then it was the Credit Crisis, now it is Europe. (When) will Greece default and which banks will implode as a result? Is there another banking crisis in our future? I just came back from a whirlwind four-country visit to Europe, and I will try to offer a few insights. This week we start with Ireland, move to the problem of Europe at large and, if we’re not out of space (and your patience!), we’ll visit some last-minute data points.
