Last month, central bankers gathered at the annual Economic Symposium in Jackson Hole, Wyoming. A lot of the talk was about the limits of monetary policy when it comes to boosting economic growth and what negative interests could do to the financial system. Bank of England Governor Mark Carney also gave a speech in which he talked about replacing the U.S. dollar's role in the financial system with something else—maybe even a central bank-run digital currency similar to Facebook's Libra. On this episode of the Odd Lots podcast, we speak with Huw van Steenis, who was senior adviser to Governor Carney and spent the last year chairing a BOE review of the 'Future of Finance.' He talks about how central banks might respond to a number of issues including the rise of new technology, the changing nature of money, and the harmful effects of negative rates.
