Federal National Mortgage Association FNMA

FNMA Company Overview

The Federal National Mortgage Association (FNMA), commonly known as Fannie Mae, is a government-sponsored enterprise operating in the U.S. housing finance and mortgage-backed securities industry. The company’s core function is to provide liquidity, stability, and affordability to the U.S. mortgage market by purchasing residential mortgages from lenders and either holding them in its portfolio or packaging them into mortgage-backed securities (MBS) with credit guarantees. Fannie Mae does not originate loans directly to consumers; instead, it operates in the secondary mortgage market, supporting banks, credit unions, and mortgage lenders.

Fannie Mae’s primary revenue drivers are guarantee fees earned for credit risk protection on MBS and interest income from its retained mortgage portfolio. Its key customers are U.S. mortgage originators and institutional investors, while its ultimate beneficiaries are homeowners and renters. A distinguishing strategic advantage is its federal charter, which mandates a public mission to support affordable housing while operating as a shareholder-owned company. Established in 1938 as part of the New Deal, Fannie Mae was reorganized in 1968 into a publicly traded entity to remove its debt from the federal balance sheet, and it has since evolved into a central pillar of the U.S. housing finance system.
