Monetary Policy Implementation with Ample Reserves
We offer a parsimonious model of the reserve demand to study the tradeoffs associated with various monetary policy implementation frameworks. Prior to the 2007–09 financial crisis, many central banks supplied scarce reserves to execute their interest-rate policies. In response to the crisis, central banks undertook quantitative-easing policies that greatly expanded their balance sheets and, by extension, the amount of reserves they supplied. When the crisis and its aftereffects passed, central banks were in a position to choose a framework that has reserves that are (1) abundant—by ...

Can the US Interbank Market be Revived?
Large-scale asset purchases by the Federal Reserve as well as new Basel III banking regulations have led to important changes in U.S. money markets. Most notably the interbank market has essentially disappeared with the dramatic increase in excess reserves held by banks. We build a model in the tradition of Poole (1968) to study whether interbank market activity can be revived if the supply of excess reserves is decreased sufficiently. We show that it may not be possible to revive the market to pre-crisis volumes due to costs associated with recent banking regulations. Although the volume of ...

A Price-Differentiation Model of the Interbank Market and Its Application to a Financial Crisis
Rate curves for overnight loans between bank pairs, as functions of loan values, can be used to infer valuation of reserves by banks. The inferred valuation can be used to interpret shifts in rate curves between bank pairs, for example, in response to a financial crisis. This paper proposes a model of lending by a small bank to a large monopolistic bank to generate a tractable rate curve. An explicit calibration procedure for model parameters is developed and applied to a dataset from Mexico around the 2008 financial crisis. During the crisis, relatively small banks were lending to large ...

Balance Sheet Policies in an Evolving Economy: Some Modelling Advances and Illustrative Simulations
Once considered "unconventional," balance sheet policies have become an integral part of the toolkit of many central banks. Increased reliance on balance sheet policies reflects in part a decline in the neutral level of interest rates, which limits central banks' ability to cut their policy rates to support the economy during downturns, and many observers expect that neutral level to remain low relative to its historical average in the coming decades.

Identification of Monetary Policy Shocks with External Instrument SVAR
We explore the use of external instrument SVAR to identify monetary policy shocks. We identify a forward guidance shock as the monetary shock component having zero instant impact on the policy rate. A contractionary forward guidance shock raises both future output and price level, stressing the relative importance of revealing policymakers' view on future output and price level over committing to a policy stance. We also decompose non-monetary structural shocks, and find that positive shocks to output and price level lead to monetary contraction. Since information on output and price level is ...

The Macroeconomic Implications of CBDC: A Review of the Literature
This paper provides an overview of the literature examining how the introduction of a CBDC would affect the banking sector, financial stability, and the implementation and transmission of monetary policy in a developed economy such as the United States. A CBDC has the potential to improve welfare by reducing financial frictions in deposit markets, by boosting financial inclusion, and by improving the transmission of monetary policy. However, a CBDC also entails noteworthy risks, including the possibility of bank disintermediation and associated contraction in bank credit, as well as potential ...

Monetary Policy Implementation with an Ample Supply of Reserves
Methods of monetary policy implementation continue to change. The level of reserve supply—scarce, abundant, or somewhere in between—has implications for the efficiency and effectiveness of an implementation regime. The money market events of September 2019 highlight the need for an analytical framework to better understand implementation regimes. We discuss major issues relevant to the choice of an implementation regime, using a parsimonious framework and drawing from the experience in the United States since the 2007–09 financial crisis. We find that the optimal level of reserve supply ...
