Treasury notes and mortgage-backed securities (MBS) are both fixed-income investments, but they differ in several key aspects. Understanding these similarities and differences is crucial for investors seeking to diversify their portfolios and manage risk effectively.
Similarities:
1. Fixed-Income Nature: Both Treasury notes and MBS are fixed-income investments that provide regular interest payments to investors. They are considered relatively safer investments compared to equities due to their fixed returns.
2. Government-Backed: Treasury notes are issued by the U.S. Department of the Treasury and are backed by the full faith and credit of the U.S. government. Similarly, MBS are indirectly backed by the U.S. government through government-sponsored enterprises (GSEs) such as
Fannie Mae and
Freddie Mac. This backing enhances the creditworthiness of both investments.
3. Liquidity: Both Treasury notes and MBS are highly liquid investments, meaning they can be easily bought or sold in the secondary market. This liquidity allows investors to quickly convert their investments into cash if needed.
Differences:
1. Issuer: Treasury notes are issued directly by the U.S. government, while MBS are created by financial institutions such as banks or
mortgage lenders. The U.S. government issues Treasury notes to finance its operations, while MBS are created by pooling together individual mortgages.
2. Risk Profile: Treasury notes are considered one of the safest investments available because they are backed by the U.S. government. They have virtually no credit risk, meaning the likelihood of default is extremely low. On the other hand, MBS carry credit risk as they are dependent on the performance of the underlying mortgages. If borrowers default on their mortgage payments, it can impact the value and returns of MBS.
3.
Interest Rate Sensitivity: Treasury notes are highly sensitive to changes in interest rates. When interest rates rise, the value of existing Treasury notes decreases, leading to potential capital losses for investors who sell before maturity. In contrast, MBS are also sensitive to interest rate changes, but in a different way. When interest rates fall, homeowners may
refinance their mortgages, resulting in the early repayment of the underlying loans. This can lead to a decrease in the expected duration of MBS, affecting their price and returns.
4.
Cash Flow Structure: Treasury notes pay interest semi-annually and return the principal amount at maturity. In contrast, MBS provide monthly cash flows to investors, consisting of both interest and principal payments from the underlying mortgages. The cash flow structure of MBS can be more complex due to factors such as prepayments and defaults.
5. Market Accessibility: Treasury notes are widely accessible to individual investors through various channels, including auctions, brokers, and financial institutions. MBS, on the other hand, are primarily traded in institutional markets and are less accessible to individual investors.
In summary, while both Treasury notes and mortgage-backed securities are fixed-income investments, they differ in terms of issuer, risk profile,
interest rate sensitivity, cash flow structure, and market accessibility. Treasury notes are considered safer with lower credit risk and higher liquidity, while MBS carry credit risk and are influenced by changes in interest rates and mortgage prepayments. Understanding these similarities and differences is essential for investors to make informed decisions when constructing a diversified fixed-income portfolio.
