FORTUNE -- David Herro seems awfully relaxed for a man who has more than $1 billion invested in European banks. It's a sunny morning in late May, and I'm sitting across from the boyish 51-year-old fund manager in his downtown Chicago office. He's giving me his full attention, but I can't stop glancing at the headlines blinking on the Bloomberg terminal behind him. The euro is about to hit a two-year low. Greece is on the brink of disaster. Spain's real estate market is in shambles, and Italian sovereign debt is as fragile as stained glass. The global economy is roiling, and Herro is positively beatific.
"Eventually they're going to get these problems solved," he says. "If you look at the economic history of the world, problems come and problems go. There are problems, and they do have to be dealt with. And our view is that all these problems are manageable."
