Federal National Mortgage Association Definition
The United States Federal Government created the Federal National Mortgage Association (FNMA), commonly known as Fannie Mae, in 1938 to establish a secondary market for mortgages insured by the Federal Housing Administration (FHA). Fannie Mae buys mortgages on the secondary market, pools them and sells them as mortgage-backed securities to investors on the open market. This secondary mortgage market helps to replenish the supply of lendable money for mortgages and ensures that money continues to be available for new home purchases.
