Dans quelle mesure une monnaie numérique de banque centrale (MNBC) concurrence-t-elle les dépôts bancaires? Pour répondre à cette question, nous élaborons et estimons un modèle structurel dans lequel chaque ménage choisit l’institution financière où déposer son argent numérique. Les ménages évaluent les intérêts servis sur l’argent numérique, la possibilité d’obtenir des produits financiers complémentaires et l’accès aux services en succursale. Une MNBC ne portant pas intérêt et non assortie de produits financiers complémentaires ne peut évincer dans une large mesure les dépôts bancaires que si elle est associée à un réseau de services étendu. L’imposition d’une limite élevée à la détention de MNBC atténuerait efficacement cet effet d’éviction.
To what extent does a central bank digital currency (CBDC) compete with bank deposits? To answer this question, we develop and estimate a structural model where each household chooses which financial institution to deposit their digital money with. Households value the interest paid on digital money, the possibility of obtaining complementary financial products, and the access to in-branch services. A non-interest-bearing CBDC that does not provide complementary financial products can substantially crowd out bank deposits only if it provides an extensive service network. Imposing a large limit on CBDC holding would effectively mitigate this crowding out.
