Mortgage-backed securities are bonds that use a pool of home loans, including residential mortgages, as collateral. Once created by a bank or investment company, the pool is sold to a federal agency, state institution, or investment firm where it is then used as collateral for a mortgage-backed security.
Investing in an MBS can be a complicated process for investors. It is important to find trustworthy issuers and understand the rules that will determine your investment return.
How Mortgage-Backed Securities (MBS) Work
Mortgage-backed securities are created when a bank or other financial company that owns mortgage loans consolidates multiple mortgages based on similar characteristics such as the interest rate and repayment period. Fixed rate mortgages, variable rate mortgages, and residential mortgages can form an MBS.
Once a pool is created, it is sold to an MBS issuer to securitize the pool and create an MBS. Issuers include government agencies (like Ginnie Mae), state-sponsored institutions (like Fannie Mae and Freddie Mac), or private investment firms (known as private label MBS). Government agencies offer the strongest guarantee of payments on their MBS as private or government sponsored entities.
After that, you can buy an MBS through a broker.
“When you invest in mortgage-backed securities, you are lending money to home buyers,” said Lyle Solomon, bankruptcy attorney with Oak View Law Group in California. “So in return you have the right to the money (or homebuyer mortgage) that you lend.”
Essentially, MBS bond holders are rewarded with monthly payments of interest and principal. In the early days of the MBS investment, the monthly payments consist mainly of interest. Over time, they contain more capital in the amount.
An MBS makes monthly payments to investors as the secured mortgage homeowners make their mortgage payments on a monthly basis. Much like mortgage payments, MBS payment amounts vary from month to month.
Types of Mortgage Backed Securities
The two main types of mortgage-backed securities are pass-throughs and collateralized mortgage obligations (CMOs).
Pass-through are a standard MBS in which the issuer collects mortgage payments in a trust and distributes – or forwards – the money to the investors. Pass-through MBS usually have a term of five, 15 or 30 years. On average, however, they last significantly shorter than the specified term, as the payments depend on how the underlying mortgages are repaid.
Secured Mortgage Liabilities are more complicated because they consist of several pools of securities, the so-called tranches or slices, and not a pool of similarly characterized mortgages. Each pool in a CMO has its own characteristics, including interest and capital allocation rules. These payments are made to the various classes of security according to a specific payment priority.
Advantages and Disadvantages of Mortgage-Backed Securities
Mortgage-backed securities can offer great diversification to an investment portfolio. They are an investment that also offers monthly payouts, which can appeal to investors who want extra income every month. However, these payments vary in size, which does not provide the consistency some investors want from their income streams.
MBS are subject to the risks inherent in the secured mortgages. Homeowners can refinance their loans, which can result in early repayment or early withdrawal of capital to investors. As an investment, an MBS also exposes investors to the market and
MBS vs. Bonds
MBS differ greatly from other bonds in terms of their payment structure. Bonds typically redeem principal semi-annually or when due, while MBS make both interest and principal payments monthly.
Government bonds such as Treasury and EE savings bonds tend to have lower investment thresholds. For example, a government bond requires a minimum of $ 100 to purchase and an EE bond only requires $ 25 to purchase. MBS are known for having higher minimum investment requirements, typically around $ 10,000.
The financial souvenir
Mortgage-backed securities are complex investments that require a great deal of research and care. First, you want to make sure that you are buying from a legitimate issuer. You can also enlist the help of an investment professional to find an MBS that will deliver the returns you want.
It also takes a considerable amount of money to buy an MBS, which makes these bonds very difficult for beginners.
