Federal Reserve Monetary Policy Tools
Source:Federal Reserve Board of Governors, Policy Tools documentation. The Fed's toolkit has expanded significantly since the 2008 financial crisis, with several tools introduced or modified during the COVID-19 pandemic and 2023 banking stress.
Overview
The Federal Reserve implements monetary policy through a suite of tools designed to influence the federal funds rate and broader financial conditions. The current framework, known as the "ample reserves" regime, relies primarily on administered rates (IORB and ON RRP) rather than active management of reserve supply through daily open market operations.
This is a departure from the pre-2008 "scarce reserves" framework, where the New York Fed's Trading Desk actively managed the supply of reserves through daily repo operations to keep the federal funds rate at its target. The shift occurred because the Fed's balance sheet expanded enormously through quantitative easing programs, flooding the banking system with reserves far beyond required levels.
Policy Tools Reference
Open Market Operations (OMOs)
The purchase and sale of U.S. Treasury securities and agency mortgage-backed securities (MBS) by the Federal Reserve Bank of New York's Open Market Trading Desk. Permanent OMOs (outright purchases/sales) change the size of the Fed's balance sheet. Temporary OMOs (repo and reverse repo) provide short-term liquidity management.
Interest on Reserve Balances (IORB)
Rate paid on balances held by depository institutions at Federal Reserve Banks. Replaced the separate IOER (interest on excess reserves) and IORR (interest on required reserves) rates in July 2021 when reserve requirements were eliminated. Set by the Board of Governors. Currently the primary tool for steering the effective federal funds rate within the target range.
Overnight Reverse Repurchase Agreement Facility (ON RRP)
Facility operated by the New York Fed that offers overnight reverse repos to eligible counterparties (primarily money market funds, banks, and government-sponsored enterprises). Counterparties lend cash to the Fed and receive Treasury securities as collateral. The ON RRP rate acts as a floor for the federal funds rate by providing a risk-free overnight investment alternative.
Discount Window
Lending facility that allows depository institutions to borrow reserves directly from their regional Federal Reserve Bank. Three programs: Primary Credit (for generally sound institutions, at a rate above the fed funds target), Secondary Credit (for institutions not eligible for primary, at a higher rate), and Seasonal Credit (for small institutions with seasonal funding needs). Historically carried stigma -- banks were reluctant to borrow for fear of signaling weakness.
Standing Repo Facility (SRF)
Established in July 2021 to serve as a backstop in money markets. Offers overnight repos to primary dealers and eligible depository institutions at a rate set by the FOMC (currently the top of the target range). Designed to dampen upward pressure on money market rates during periods of stress, as demonstrated by the September 2019 repo market disruption.
Reserve Requirements
Historically, depository institutions were required to hold a fraction of certain deposits as reserves (either vault cash or deposits at the Fed). Required reserve ratios were 10% for transaction deposits above a threshold and 0% for savings and time deposits. In March 2020, the Board reduced reserve requirement ratios to 0% for all deposit categories, effectively eliminating reserve requirements. This has not been reversed.
Quantitative Easing (QE) / Large-Scale Asset Purchases
Large-scale purchases of longer-term Treasury securities and agency MBS to put downward pressure on longer-term interest rates when short-term rates are at or near zero. The Fed conducted QE programs in 2008-2014 (QE1, QE2, QE3/Operation Twist) and again in 2020 (COVID-19 response, purchasing $120 billion per month in Treasuries and MBS at peak). Expands the Fed's balance sheet significantly.
Quantitative Tightening (QT) / Balance Sheet Runoff
The process of reducing the Fed's balance sheet by allowing maturing securities to roll off without reinvestment, or by actively selling securities. The Fed began QT in June 2022 at a pace of up to $95 billion per month ($60B Treasuries + $35B MBS), later slowed to $60 billion per month ($25B Treasuries + $35B MBS) in June 2024. Mechanically the opposite of QE.
Emergency Lending -- Section 13(3)
Under Section 13(3) of the Federal Reserve Act, the Fed can establish emergency lending facilities with approval from the Treasury Secretary during "unusual and exigent circumstances." Used in 2008 (Bear Stearns, AIG, multiple facilities) and 2020 (Municipal Liquidity Facility, Main Street Lending, Corporate Credit Facilities, TALF, PPPLF, among others). Dodd-Frank Act (2010) added the requirement for Treasury Secretary approval and prohibited lending to individual firms.
Bank Term Funding Program (BTFP)
Created in March 2023 in response to the failures of Silicon Valley Bank and Signature Bank. Offered loans of up to one year to depository institutions, pledging Treasuries and agency MBS as collateral valued at par (face value rather than market value). This was significant because many banks held securities with large unrealized losses due to the 2022-2023 rate hikes. The program stopped making new loans on March 11, 2024.
The Ample Reserves Framework
In January 2019, the FOMC announced it would continue to implement monetary policy in a regime of ample reserves. In this framework, the Fed controls short-term interest rates primarily through the IORB rate (which sets the rate banks earn on reserves at the Fed) and the ON RRP rate (which sets the rate available to non-bank counterparties).
The effective federal funds rate typically trades a few basis points below IORB, because some participants in the federal funds market (notably Federal Home Loan Banks) are not eligible to earn IORB and are therefore willing to lend at a slightly lower rate. The ON RRP rate provides the floor -- no institution would lend at a rate below what the Fed offers on overnight reverse repos.
