UniBe Discussion Paper 22-12, October 2022. PDF. We analyze retail central bank digital currency (CBDC) in a two-tier monetary system with bank deposit market power and externalities from liquidity transformation. Resource costs of liquidity provision determine the optimal monetary architecture and modified Friedman (1969) rules the optimal monetary policy. Optimal interest rates on reserves and CBDC differ. A calibration for the U.S. suggests a weak case for CBDC in the baseline but a...

VoxEU, February 5, 2021. HTML. Based on CEPR DP 15457, I assess possible implications of the introduction of retail CBDC for bank profits. The model implies annual implicit subsidies to U.S. banks of up to 0.8 percent of GDP during the period 1999-2017.

CEPR Discussion Paper 15457, November 2020. PDF (local copy). We analyze policy in a two-tiered monetary system. Noncompetitive banks issue deposits while the central bank issues reserves and a retail CBDC. Monies differ with respect to operating costs and liquidity. We map the framework into a baseline business cycle model with “pseudo wedges” and derive optimal policy rules: Spreads satisfy modified Friedman rules and deposits must be taxed or subsidized. We generalize the...

In the FT, Sam Fleming and Demetri Sevastopulo report that the White House considers Marvin Goodfriend for the Federal Reserve’s Board of Governors. He has criticised the Fed’s crisis-era balance sheet expansion, saying the central bank should generally not purchase mortgage-backed securities, and has advocated the use of monetary policy rules to guide policy, as has Mr Quarles. … At the same time, however, Mr Goodfriend has been willing to contemplate the use of deeply negative rates to...

In another excellent post on Moneyness, J P Koning likens the monetary system to the plot in the movie Inception, featuring a dream piled on a dream piled on a dream piled on a dream. Koning explains that [l]ike Inception, our monetary system is a layer upon a layer upon a layer. Anyone who withdraws cash at an ATM is ‘kicking’ back into the underlying central bank layer from the banking layer; depositing cash is like sedating oneself back into the overlying banking layer. Monetary...

In the FT, Mehreen Khan reports about the resurgence of deposit flight.

The Federal Council aims at strengthening the deposit insurance system and has asked the ministry of finance to work out new rules. Banks will have to pledge securities as collateral, rather than solely contribute cash ex post. The council rejects the proposal to prefund a deposit fund.

On VoxEU, Charles Calomiris and Matthew Jaremski discuss the origins of bank liability insurance. They argue that it is redistribution, not the aim to boost efficiency, which explains a lot of the action. … there are two theoretical approaches to explaining the creation and expansion of deposit insurance. The first is an economic approach grounded in potential efficiency gains from limiting bank runs (i.e. the public interest motivation). The second is a political approach grounded in the...
