Which entity issues mortgage-backed securities that are fully guaranteed by the U.S. government?

The Government National Mortgage Association (GNMA), commonly known as Ginnie Mae, is the entity responsible for issuing mortgage-backed securities that are fully guaranteed by the U.S. government. This guarantees investors the timely payment of principal and interest, which provides a level of security that encourages investment in these instruments.

Ginnie Mae focuses specifically on the backing of mortgage loans made to homeowners and provides an essential role in the housing finance system, particularly by ensuring that capital is available for federally insured or guaranteed mortgage loans. This backing helps to stabilize the mortgage market and provide liquidity, which can lead to lower interest rates for consumers.

In contrast, the Federal Housing Administration primarily insures loans but does not issue securities itself. The Securities and Exchange Commission oversees securities markets and protects investors but does not guarantee any mortgage-backed securities. The Federal Reserve, while it plays a significant role in monetary policy and sometimes interacts with mortgage-backed securities, does not issue these securities or guarantee them.
