What are Mortgage-Backed Securities?

Mortgage-Backed Securities (MBS) are created when financial institutions bundle together a large number of mortgage loans into a single investment product. These loans can include residential mortgages, such as those used for purchasing homes or refinancing existing mortgages. The MBS are then sold to investors, who essentially become the owners of a portion of the underlying mortgage loans.
Investors in MBS receive periodic payments, primarily in the form of interest and principal repayments made by the homeowners. These payments are distributed among the investors based on their proportionate ownership of the MBS. By investing in MBS, individuals can indirectly participate in the housing market and earn income from the mortgage payments made by homeowners.

Types of Mortgage-Backed Securities

Pass-Through Securities

Pass-Through Securities are the most common type of MBS. They provide investors with a pro-rata share of the cash flows generated by the underlying mortgage loans. The principal and interest payments made by the homeowners are passed through to the investors, who receive regular payments based on the pool of mortgages.

Collateralized Mortgage Obligations (CMOs)

Collateralized Mortgage Obligations (CMOs) are a type of MBS that offer different risk and return profiles through tranches. Tranches represent different segments of the mortgage pool, each with its own characteristics. CMOs allow investors to choose tranches that align with their risk tolerance and investment objectives.

Mortgage-Backed Bonds

Mortgage-Backed Bonds are securities backed by a pool of mortgage loans. They typically offer fixed interest rates and maturities ranging from several years to several decades. These bonds provide investors with predictable cash flows over the life of the investment.
