Digital currencies like Bitcoin often make headlines for the massive swings in their value, but beyond the intrigue of skyrocketing and plummeting prices the rising popularity of cryptocurrencies poses serious questions for financial institutions and monetary policy. Eswar Prasad joins David Dollar for a conversation on the digitalization of money and what digital currencies could mean for the future of cash, international payments, and the strength of the U.S. dollar. Prasad also explains why some central banks have hesitated to introduce digital currencies while others have embraced them. Dollar & Sense is part of the Brookings Podcast Network.
