Definition of 'Mortgage-Backed Security (MBS)'
A type of asset-backed security that is secured by a mortgage or collection of mortgages. These securities must also be grouped in one of the top two ratings as determined by a accredited credit rating agency, and usually pay periodic payments that are similar to coupon payments.

Also known as a "mortgage-related security" or a "mortgage pass through."

When you invest in a mortgage-backed security you are essentially lending money to a home buyer or business. An MBS is a way for a smaller regional bank to lend mortgages to its customers without having to worry about whether the customers have the assets to cover the loan. Instead, the bank acts as a middleman between the home buyer and the investment markets.
This type of security is also commonly used to redirect the interest and principal payments from the pool of mortgages to shareholders. These payments can be further broken down into different classes of securities, depending on the riskiness of different mortgages as they are classified under the MBS.
Definition of 'Commercial Mortgage-Backed Securities (CMBS)'
A type of mortgage-backed security that is secured by the loan on a commercial property. A CMBS can provide liquidity to real estate investors and to commercial lenders. As with other types of MBS, the increased use of CMBS can be attributable to the rapid rise in real estate prices over the years.

Because they are not standardized, there are a lot of details associated CMBS that make them difficult to value. However, when compared to a residential mortgage-backed security (RMBS), a CMBS provides a lower degree of prepayment risk because commercial mortgages are most often set for a fixed term.
