CEPR Discussion Paper 21141, February 2026. PDF.

We review the macroeconomic literature on retail central bank digital currency (CBDC), organizing the discussion around a CBDC-irrelevance result. We identify both fundamental and policy-related sources of relevance, or departures from neutrality. Bank disintermediation—the crowding out of deposits—does not, by itself, constitute such a source. We argue that the literature has primarily focused on policy-related sources of non-neutrality, often without making this focus explicit. From a macroeconomic perspective, CBDC is, at its core, a matter of monetary architecture, and political economy considerations are central to understanding CBDC policy design.
