What is a mortgage-backed security?
A mortgage-backed security (MBS) is a type of asset-backed security that is secured by a mortgage or collection of mortgages. The mortgages are sold to a group of individuals (a government agency or investment bank) that securitizes, or packages, the loans together into a security that can be sold to investors. The principal and interest payments from the underlying mortgages are passed through to the MBS holder.
How do mortgage-backed securities work?
Mortgage-backed securities are created when a lender (such as a bank) originates a mortgage loan and then sells the loan to an entity (such as a government agency or investment bank) that securitizes the loans. The entity that securitizes the loans packages the loans together into a security that can be sold to investors. The entity that securitizes the loans also provides a guarantee that the payments on the underlying mortgages will be made even if some of the borrowers default on their loans.
The benefits of investing in mortgage-backed securities
Mortgage-backed securities offer a number of benefits to investors. First, they are backed by a physical asset - a mortgage - which provides some level of security in the event of default. Second, they offer a higher yield than other types of fixed-income securities, such as government bonds. And third, they offer the potential for capital appreciation if the underlying mortgages are paid off early or if interest rates decline.
The risks of investing in mortgage-backed securities
Mortgage-backed securities are not without risk, however. The most significant risk is credit risk - the risk that the borrowers will default on their loans. This risk is mitigated to some extent by the fact that the loans are typically securitized by a government agency or investment bank, but it cannot be completely eliminated. Interest rate risk is also a concern, as rising interest rates can lead to lower prices for MBS. And finally, prepayment risk - the risk that the underlying mortgages will be paid off early - can also lead to lower prices for MBS.
Top tips for investing in mortgage-backed securities
If you're considering investing in mortgage-backed securities, here are a few things to keep in mind:
- Understand the risks. Be sure to understand the risks involved before you invest. Credit risk, interest rate risk, and prepayment risk can all lead to losses.
- Diversify your portfolio. Don't put all your eggs in one basket. Diversifying your portfolio with different types of investments can help reduce your overall risk.
- Work with a financial advisor. A financial advisor can help you understand the risks and potential rewards of investing in mortgage-backed securities and make sure they're appropriate for your investment goals.
