When Are Central Bank Reserves Ample?
The Federal Reserve (Fed) implements monetary policy in a regime of ample reserves, whereby short-term interest rates are controlled mainly through the setting of administered rates. To do so, the quantity of reserves in the banking system needs to be large enough that everyday changes in reserves do not cause large variations in the policy rate, the so-called federal funds rate. As the Fed shrinks its balance sheet following the plan laid out by the Federal Open Market Committee (FOMC) in 2022, how can it assess when to stop so that the supply of reserves remains ample? In the first post of ...

Banks’ Balance-Sheet Costs and ON RRP Investment
Daily investment at the Federal Reserve’s Overnight Reverse Repo (ON RRP) facility increased from a few billion dollars in March 2021 to more than $2.3 trillion in June 2022 and has stayed above $2 trillion since then. In this post, which is based on a recent staff report, we discuss two channels—a deposit channel and a wholesale short-term debt channel—through which banks’ balance-sheet costs have increased investment by money market mutual funds (MMFs) in the ON RRP facility.

The Over-the-Counter Theory of the Fed Funds Market: A Primer
We present a dynamic over-the-counter model of the fed funds market and use it to study the determination of the fed funds rate, the volume of loans traded, and the intraday evolution of the distribution of reserve balances across banks. We also investigate the implications of changes in the market structure, as well as the effects of central bank policy instruments such as open market operations, the discount window lending rate, and the interest rate on bank reserves.

Stressed, not frozen: the Federal Funds market in the financial crisis
We examine the importance of liquidity hoarding and counterparty risk in the U.S. overnight interbank market during the financial crisis of 2008. Our findings suggest that counterparty risk plays a larger role than does liquidity hoarding: the day after Lehman Brothers? bankruptcy, loan terms become more sensitive to borrower characteristics. In particular, poorly performing large banks see an increase in spreads of 25 basis points, but are borrowing 1 percent less, on average. Worse performing banks do not hoard liquidity. While the interbank market does not freeze entirely, it does not seem ...

Monetary Policy Transmission and the Size of the Money Market Fund Industry: An Update
The size of the money market fund (MMF) industry co-moves with the monetary policy cycle. In a post published in 2019, we showed that this co-movement is likely due to the stronger response of MMF yields to monetary policy tightening relative to bank deposit rates, combined with MMF shares and bank deposits being close substitutes from an investor’s perspective. In this post, we update the analysis and zoom in to the current monetary policy tightening by the Federal Reserve.

Scarce, Abundant, or Ample? A Time-Varying Model of the Reserve Demand Curve
What level of central bank reserves satiates banks’ demand for liquidity? We estimate the slope of the reserve demand curve in the U.S. over 2010–2024 using a time-varying instrumental-variable approach at the daily frequency. When reserves exceed 12-13 percent of banks’ assets, demand for reserves is satiated and reserves are abundant; below this threshold, the curve’s slope becomes increasingly negative as reserves decline from ample to scarce. We also find that reserve demand has shifted over time, both vertically and horizontally, and identify important drivers of vertical shifts. ...

How Have High Reserves and New Policy Tools Reshaped the Fed Funds Market?
Over the last decade, the federal funds market has evolved to accommodate new policy tools such as interest on reserves and the overnight reverse repo facility. Trading motives have also responded to the expansion in aggregate reserves as the result of large-scale asset purchases. These changes have affected market participants differently since, for instance, not all institutions are required to keep reserves at the Fed and some are not eligible to earn interest on reserves. Differential effects have changed the profile of participants willing to borrow and lend in this market, and this ...

Mission Almost Impossible: Developing a Simple Measure of Pass-Through Efficiency
Short-term credit markets have evolved significantly over the past ten years in response to unprecedentedly high levels of reserve balances, a host of regulatory changes, and the introduction of new monetary policy tools. Have these and other developments affected the way monetary policy shifts “pass through” to money markets and, ultimately, to households and firms? In this post, we discuss a new measure of pass‑through efficiency, proposed by economists Darrell Duffie and Arvind Krishnamurthy at the Federal Reserve’s 2016 Jackson Hole summit.

Monetary Policy Implementation with an Ample Supply of Reserves
We offer a parsimonious model of the reserve demand to study the trade-offs associated with various monetary policy implementation frameworks. Our model considers a reserve demand function that encompasses banks' preferences for reserves in the post 2007-2009 financial crisis world and incorporates shocks to the demand for and the supply of reserves. We find that the best policy implementation outcomes are realized when reserves are somewhere in between scarce and abundant. This outcome is consistent with the Federal Open Market Committee's 2019 announcement to implement monetary policy in a ...

How the Fed’s Overnight Reverse Repo Facility Works
Daily take-up at the overnight reverse repo (ON RRP) facility increased from less than $1 billion in early March 2021 to just under $2 trillion on December 31, 2021. In the second post in this series, we take a closer look at this important tool in the Federal Reserve’s monetary policy implementation framework and discuss the factors behind the recent increase in volume.
