Fed governor Daniel Tarullo, speaking at a Wall Street Journal/WSJ Pro event, said there have been many changes since the financial crisis, with big banks building up capital, reducing their dependence on shorter-term wholesale funding, and better understanding and manage their risks. But there will be more. “Obviously, our aim is to get to a point where we can say that the financial system is, relatively speaking, stable, safer, sounder – certainly more stable, safer, and sounder than it was a decade ago.”
