Introduction
Mortgage-Backed Securities (MBS) are an essential segment of U.S. government securities covered under the FINRA Series 7 exam. This guide dives into MBS, providing insights into pass-through certificates and the associated prepayment risks. Enhance your understanding through detailed explanations and quizzes tailored to help you succeed in the Series 7 exam.
What are Mortgage-Backed Securities?
Mortgage-Backed Securities (MBS) are investments composed of a collection of home loans bought from the banks that issued them. They offer a way for investors to earn from the mortgage market.
Pass-Through Certificates
Pass-through certificates are a type of MBS where mortgage payments from borrowers are directly passed through to investors. These securities represent a partial ownership in the pool of mortgages and typically pay principal and interest monthly.
This process can be represented through the following flowchart:

Prepayment Risk
One significant risk inherent in MBS is prepayment risk. This occurs when homeowners pay off their mortgages faster than expected, usually due to refinancing during a decline in interest rates. As a result, investors may receive their principal back sooner but might miss out on higher interest earnings.
Key Considerations for Investors
Investors need to balance their pursuit of steady income from MBS with the potential for sudden prepayments, which could necessitate reinvesting at lower interest rates.
Mathematical Representation
To understand this risk better, the yield calculations for MBS might involve adjustments for prepayment speeds, often expressed using the formula:
$$
\text{Adjusted Yield} = \frac{\text{Expected Coupon Payment} - \text{Prepayments}}{\text{Investment Principal}}
$$
Conclusion
Mortgage-Backed Securities offer a diversified and potentially rewarding investment opportunity, but they come with inherent risks such as prepayment. Understanding these aspects is crucial for aspiring securities representatives.
