We develop a new framework to examine the effects of retail central bank digital currencies (CBDCs) on financial inclusion and stability, particularly how the results depend on an economy's existing degree of financial development. We demonstrate that when offering CBDCs in underdeveloped economies, some households migrate from cash to CBDCs. However, the competition between CBDCs and non-bank-issued electronic money (e-money) poses a significant threat to disintermediate banks. When offering CBDCs in developed economies, few households migrate from cash to CBDCs. Nevertheless, CBDCs can effectively constrain non-bank e-money and hence strengthening financial stability. Overall, our findings suggest that retail CBDCs can be useful for promoting financial inclusion only in underdeveloped economies and strengthening financial stability in terms of curbing non-bank e-money only in developed ones. An economy needs to consider the motivations and existing degree of financial development when offering CBDCs.
