The Federal Reserve is the single largest holder of mortgage-backed securities (MBS). As of October 2021, its total holdings of agency MBS amounted to approximately $2.5 trillion, primarily accumulated through its large-scale asset purchase programs.
Understanding the Federal Reserve's Role
The Federal Reserve, as the central bank of the United States, plays a crucial role in maintaining economic stability and influencing financial markets. Its substantial holdings of mortgage-backed securities are a key component of its monetary policy toolkit, often referred to as quantitative easing (QE).
- Policy Objective: The primary goal of purchasing MBS is to lower long-term interest rates, particularly mortgage rates, thereby stimulating the housing market, encouraging borrowing, and supporting broader economic growth. By increasing the demand for MBS, the Fed helps to push down yields, which translates into lower rates for consumers.
- Market Liquidity: These purchases also aim to ensure smooth functioning and liquidity in the mortgage market, especially during periods of financial stress.
- Economic Stimulus: The large-scale asset purchases were particularly prominent in the aftermath of the 2008 financial crisis and during the COVID-19 pandemic, serving as a powerful tool to inject liquidity into the financial system and provide economic stimulus.
Here's a snapshot of the Federal Reserve's MBS holdings:

What Are Mortgage-Backed Securities (MBS)?
Mortgage-backed securities are financial instruments that represent claims on the cash flows generated by a pool of mortgage loans. Essentially, individual mortgages are bundled together, and investors can buy shares of these bundles.
- Securitization: This process, known as securitization, allows lenders to sell their mortgages to investors, freeing up capital to issue new loans.
- Types of MBS: The Federal Reserve primarily holds agency MBS. These are MBS guaranteed by government-sponsored enterprises (GSEs) such as Fannie Mae, Freddie Mac, and government agencies like Ginnie Mae. The guarantee significantly reduces the credit risk for investors, making them a very liquid and attractive asset class.
- Investor Base: While the Federal Reserve is the largest holder, other significant investors in MBS include banks, insurance companies, pension funds, and asset managers, all seeking stable income streams and portfolio diversification.
