No one has the right to not assume that the business cycle will turn! Every five years or so, you have got to assume that something bad will happen.

Europe is the most complicated place, in my opinion.

If you were a corporation needing financial services, and I can give you something better, faster, and cheaper across 12 products as opposed to eight, that's business. I'm doing it because I'm serving you; I'm not doing it because I want to be universal.

I also think you have to be very careful. I mean, the heritage of our company is very strong, and building some of these businesses into leading players is extremely tough. You and I can both build a trading business, and it looks like you're doing OK, and it looks like I'm doing OK. But, really, I am, and you aren't. It comes down to the quality of clients, quality of systems, quality of risk controls.

You've seen certain credit type products that are going to be in nonbanks, like sophisticated CLO [collateralized loan obligation] tranches and stuff where the capital charge is so high that a bank simply will not own it. Someone will buy it, hedge it, trade it. But it won't typically be a bank.

My operating assumption is we will always have very tough competition. And even with some European banks struggling right now, some of them can reemerge - and maybe even stronger.

The yen is trading where it's trading because people are guessing about people's future interest rates, dollar and yen and about the future growth potential of the economies. And, if this policy works, then the yen will probably strengthen.
