Introduction

We explore the implications of introducing a central bank digital currency (CBDC) through commercial banks that differ in size. We focus on two design features of CBDCs: interest-bearing and payment convenience, which correspond to “store of value” and “medium of exchange” properties of currencies. A CBDC that pays interest to users enhances monetary policy passthrough, but it harms small banks by shifting deposits and lending activities to large banks. In contrast, a CBDC that delivers its own convenience value to users levels the playing field by shifting deposits and lending from large banks to small ones, and it can enhance or reduce the transmission of monetary policy. We construct an interest rate-vs-convenience frontier for CBDC design, and show how a central bank’s optimal choice of CBDC can be obtained by interacting the CBDC frontier with its own objective mix between monetary policy passthrough and market competition.
