A single agency responsible for systemic risk would be accountable in a way that no regulator was in the run-up to the 2008 crisis. With access to all necessary information to monitor the markets, this regulator would have a better chance of identifying and limiting the impact of future speculative bubbles.

It's a safe banking system, a sound banking system. Our regulators are on top of it. This is a very manageable situation.

My preference is for the Federal Reserve to be the systemic risk regulator, because the responsibility for identifying and limiting potential problems is a natural complement to its role in monetary policy.

I didn't get the charm gene.

Even if you don't have the authorities - and frankly I didn't have the authorities for anything - if you take charge, people will follow.

As a child, I could beat most kids in sprints, but overall, wrestling was the most natural sport for me. In fact, I was a pretty good high school wrestler. I was unusually quick and strong.

In just about every area of society, there's nothing more important than ethics.
