“Money and Banking with Reserves and CBDC,” CEPR, 2023

CEPR Discussion Paper 18444, September 2023. HTML (local copy).

Abstract:

We analyze the role of retail central bank digital currency (CBDC) and reserves when banks exert deposit market power and liquidity transformation entails externalities. Optimal monetary architecture minimizes the social costs of liquidity provision and optimal monetary policy follows modified Friedman (1969) rules. Interest rates on reserves and CBDC should differ. Calibrations robustly suggest that CBDC provides liquidity more efficiently than deposits unless the central bank must refinance banks and this is very costly. Accordingly, the optimal share of CBDC in payments tends to exceed that of deposits.

  • Banks increasingly face competition in bread-and-butter businesses like term deposits, lending and payments.
  • Two trends shape the sector’s changes: Falling trust in banks, both at the political level and by individual clients; and the rise of the internet.
  • Trust has been squandered. But with cheap access to information, it also has lost importance.
  • Asymmetric information in financial markets might become less of a friction. This could turn into an existential threat for banks.
  • When trust is less important and technology more versatile, increasing returns to scale in the provision of financial services might be a thing of the past. And so the universal bank. New regulatory and tax regimes could foster the process of structural change.
