Bitcoin and Beyond

The surging price of the world’s best-known cryptocurrency has made some investors rich and prompted skeptics to point to the excesses of the current bull market. Central bank digital currencies (CBDCs) may offer a surer route to greater financial inclusion, but are policymakers and the public prepared for this potentially radical innovation?

In this Big Picture, Harvard University’s Kenneth Rogoff thinks that the COVID-19 pandemic could accelerate the emergence of CBDCs, and outlines two ways in which monetary policymakers could introduce them. The case for a digital dollar, however, is far from clear-cut, says Barry Eichengreen of the University of California, Berkeley, not least because fear that a digital renminbi will challenge the greenback’s global dominance is overblown. But New York University’s Nouriel Roubini makes the case that CBDCs could replace both an inherently crisis-prone banking system and worthless private cryptocurrencies such as Bitcoin.

Chatham House’s Jim O’Neill is similarly unimpressed by the Bitcoin hype, and explains why cryptocurrencies like it will never be anything more than speculative vehicles. For that reason, says Willem H. Buiter of Columbia University, only those with a robust appetite for risk and the wherewithal to absorb heavy losses should consider investing in them. By contrast, Brian Armstrong of cryptocurrency exchange Coinbase argues that cryptocurrencies with strong consumer-privacy protections should be a key feature of the post-pandemic recovery.

Either way, conclude Katharina Pistor of Columbia Law School and Co-Pierre Georg of the University of Cape Town, central banks may soon need to expand their remit and develop a new regulatory infrastructure to manage both public and private digital currencies.
