If you’re scratching your head when I say the words “mortgage backed securities”, you’re not alone. But these may be the words that will lead to you to a financial breakthrough, not only in terms of understanding, but also your investments. To take the risk or not take the risk? To answer this, one must define first what a mortgage backed security, or MBS, is. So, what exactly is a mortgage backed security?
A mortgage backed security is a type of bond that is supported by a pool of personal loans that may be used to pay for the buying of home or other types of real estate property. While these loans are being paid off, the mortgage payments then are passed to the bondholder. These bondholders will be the ones to receive payments which typically are made up of principal and interest. Take note, these types of security are also called “mortgage related security” or “mortgage pass through”.
When a mortgage loan is extended by bank, commonly a commercial, savings and loan, or thrift bank, this process starts. The lender can sell these loans one by one and have them pooled by the purchaser, or the lender can group similar mortgages before selling. What happens subsequently is that after these mortgages have been pooled into their different groups, they are then securitized and eventually sold.
Sorted into how the payment process is done, there are three main types of mortgage backed securities: collaterized mortgage obligations, stripped mortgage backed securities and traditional pass-through securities.
First, collaterized mortgage obligations are characterized by the way they permit the creation of bonds with a possibility of risk and return. Cash flows are taken from a pass-through security into what are called “tranches”. These tranches are formed to accomplish distinct return goals, and manage risks efficiently.
Secondly, the stripped mortgage back securities create one or two new securities with cash flows from the original mortgage pass-through. Each of these new securities receives either principal, interest of a combination.
Lastly, traditional pass-throughs are known to give each investor in the pool a proportional distribution of the principal and interests formed by the homeowners.
Mortgage backed securities are beneficial because they usually give a higher yield than many other types of fixed income securities. However, the risks involved with mortgage backed securities are the sensitivity of the type to interest rate movements. Prepayment speeds, in particular, have a great hand in these types of securities, because if prepayment speeds are faster than planned, the bondholders are risking that their principal will be returned earlier than expected, as well as in a lower interest rate environment.
All in all, the essence of mortgage backed securities is that they are a type of asset-backed security that secures itself through a mortgage or a set of mortgages. You are in fact lending money to a home buyer or business, or vice versa. They are often used to redirect the interest and principal payments from a pool of mortgages to shareholders.
