The Government National Mortgage Association (Ginnie Mae) is a U.S. government agency within the Department of Housing and Urban Development (HUD). Established in 1968, Ginnie Mae plays a vital role in the mortgage market by guaranteeing mortgage-backed securities (MBS) issued by approved private lenders. These securities are backed by pools of federally-insured or government-guaranteed mortgages, primarily those insured by the Federal Housing Administration (FHA), the Department of Veterans Affairs (VA), and the Rural Housing Service (RHS). Ginnie Mae's mission is to ensure that low- to moderate-income individuals and families have access to affordable housing by providing a secondary market for government-backed mortgage loans.

4. Federally-Insured Mortgages: Ginnie Mae's MBS primarily consist of mortgages insured by the FHA, VA, and RHS. These government agencies provide insurance or guarantees to lenders against borrower default.
