Mortgage-Backed Securities (MBS)
What Are Mortgage-Backed Securities?
Mortgage-backed securities (MBS) are investment products created by pooling together multiple mortgage loans and selling shares of that pool to investors.
When lenders sell mortgages into the secondary market, those loans are often bundled into securities. Investors who purchase MBS receive payments derived from borrowers’ monthly mortgage payments.
Major participants in this market include Fannie Mae and Freddie Mac, which issue securities backed by conforming loans.
Why It Matters in a Mortgage
Mortgage-backed securities influence:
- Mortgage interest rates
- Loan availability
- Lending standards
- Market liquidity
When investor demand for MBS is strong, mortgage rates tend to remain competitive. When demand weakens, rates can rise.
MBS connect individual home loans to global financial markets.
How It Works
- Lender originates mortgage.
- Loan is sold into the secondary market.
- Loans are pooled together.
- Investors buy securities backed by those loans.
Borrowers continue making payments to their loan servicer, unaware of the investor structure behind the loan.
