CBDC remuneration in a world with low or negative nominal interest rates
The prospect of central bank digital currency (CBDC) has raised concerns over its potential to cause structural (i.e. permanent) or cyclical (i.e. crisis-related, temporary) bank disintermediation. Moreover, negative interest rate policy is incompatible with the unconstrained supply of zero-remunerated CBDC. This column argues that a two-tier remuneration system for CBDC would be an efficient solution to these issues. It would allow households to access the CBDC as a means of payment with non-negative remuneration and would also make it possible to overcome the perceived dichotomy between retail and wholesale CBDC.
