David Hendler made his reputation as a bank analyst at the independent research firm CreditSights Inc., foreseeing many of the problems that led to the financial crisis of 2008 and vocally criticizing the "too good to be true" trading profits posted by big financial institutions. Today he runs his own consultancy, Viola Risk Advisors LLC. He joins us this week to talk bank business models of the past, present, and future. We tackle some of the biggest topics in the financial industry — are bond trading desks permanently broken or just on an extended vacation? What will the lender of the future look like? And where do current risks in banking lie?
