Types of Mortgage-Backed Securities: Understanding the Differences

Mortgage-backed securities (MBS) are a type of investment that has become increasingly popular over the years. These securities are created when a mortgage lender bundles a group of individual mortgages and sells them to investors. The investors who purchase these securities receive payments based on the principal and interest payments made on the underlying mortgages. However, not all mortgage-backed securities are created equal, and there are several types of MBS that investors should be aware of.

Pass-through securities are the most common type of MBS, and they are considered to be relatively low-risk investments. Collateralized mortgage obligations (CMOs), on the other hand, are a more complex type of MBS that separates the cash flows from the underlying mortgages into different tranches, each with its own risk and return profile.

Commercial mortgage-backed securities (CMBS) are another type of MBS that are backed by commercial real estate mortgages, while stripped mortgage-backed securities separate the interest and principal payments from the underlying mortgages into two separate securities. Lastly, agency mortgage-backed securities are MBS that are guaranteed by a government agency and are considered to be relatively low-risk investments.

Understanding the differences between these types of MBS is important for investors who are looking to add MBS to their investment portfolio. Each type of MBS comes with its own set of risks and potential rewards, and investors should carefully consider their investment objectives and risk tolerance before investing in any type of MBS. In this article, we will provide a comprehensive overview of the different types of mortgage-backed securities and the characteristics that make each type unique.

Mortgage-backed securities (MBS) are investment vehicles that represent ownership in pools of mortgages. These securities are created when mortgage lenders bundle together a group of individual mortgages and sell them to investors. Investors who purchase MBS receive payments based on the principal and interest payments made on the underlying mortgages. There are several types of mortgage-backed securities, each with unique characteristics and risks.

Pass-Through Securities:

The most common type of MBS is a pass-through security. In this type of security, payments made on the underlying mortgages are passed through to the investors in proportion to their ownership of the MBS. The cash flows from the mortgages are collected by a servicer, who then distributes the payments to the investors. These securities are generally considered to be low-risk, as they are backed by a pool of mortgages and provide a steady stream of income.

Collateralized Mortgage Obligations (CMOs):

Collateralized mortgage obligations (CMOs) are a type of MBS that separates the cash flows from the underlying mortgages into different classes or tranches, each with its own risk and return profile. This allows investors to choose a specific tranche that meets their investment objectives and risk tolerance. The cash flows from the mortgages are used to pay interest and principal on the different tranches, with the most senior tranches receiving the highest priority in receiving payments. CMOs can be complex and may involve prepayment risk, interest rate risk, and credit risk.

Commercial Mortgage-Backed Securities (CMBS):

Commercial mortgage-backed securities (CMBS) are a type of MBS that are backed by commercial real estate mortgages. These securities are created by pooling together a group of commercial mortgages and selling them to investors. CMBS can be more complex than residential MBS, as commercial mortgages tend to have different characteristics and risks than residential mortgages. These securities may also involve prepayment risk, interest rate risk, and credit risk.

Stripped Mortgage-Backed Securities:

Stripped mortgage-backed securities are a type of MBS that separate the interest and principal payments from the underlying mortgages into two separate securities: interest-only (IO) and principal-only (PO) securities. The interest-only securities receive only the interest payments from the underlying mortgages, while the principal-only securities receive only the principal payments. These securities can be used by investors to gain exposure to specific risks associated with mortgages, such as prepayment risk or interest rate risk.

Agency Mortgage-Backed Securities:

Agency mortgage-backed securities are MBS that are guaranteed by a government agency, such as Fannie Mae, Freddie Mac, or Ginnie Mae. These securities are considered to be low-risk, as they are backed by the full faith and credit of the U.S. government. Agency MBS are popular among investors who are seeking a low-risk investment with a relatively high yield.

Conclusion

Mortgage-backed securities are investment vehicles that represent ownership in pools of mortgages. There are several types of MBS, each with unique characteristics and risks. Pass-through securities are the most common type of MBS, while CMOs, CMBS, stripped MBS, and agency MBS offer investors different risk and return profiles. Understanding the differences between these types of securities is important for investors who are looking to add MBS to their investment portfolio.

Mortgage-backed securities (MBS) offer investors an opportunity to invest in a diversified portfolio of mortgages. However, not all MBS are created equal, and it’s important for investors to understand the different types of MBS and the risks associated with each type.

Pass-through securities are the most common type of MBS and are considered to be relatively low-risk investments. They provide investors with a steady stream of income, but they also come with prepayment risk and interest rate risk.

Collateralized mortgage obligations (CMOs) are a more complex type of MBS that separate the cash flows from the underlying mortgages into different tranches. These tranches have different risk and return profiles, and investors can choose a tranche that meets their investment objectives and risk tolerance. CMOs come with prepayment risk, interest rate risk, and credit risk.

Commercial mortgage-backed securities (CMBS) are another type of MBS that are backed by commercial real estate mortgages. These securities can be more complex than residential MBS because commercial mortgages tend to have different characteristics and risks. CMBS also come with prepayment risk, interest rate risk, and credit risk.

Stripped mortgage-backed securities separate the interest and principal payments from the underlying mortgages into two separate securities. These securities can be used by investors to gain exposure to specific risks associated with mortgages, such as prepayment risk or interest rate risk.
