A mortgage-backed security MBS is an investment similar to a bond that is made up of a bundle of home loans bought from the banks that issued them. Investors in MBS receive periodic payments similar to bond coupon payments. Mortgage-backed securities MBS are variations of asset-backed securities that are formed by pooling together mortgages exclusively.
The investor who buys a mortgage-backed security is essentially lending money to home buyers. An MBS can be bought and sold through a broker. The minimum investment varies between issuers. As became glaringly obvious in the subprime mortgage meltdown of , a mortgage-backed security is only as sound as the mortgages that back it up. An MBS may also be called a mortgage-related security or a mortgage pass-through.
Essentially, the mortgage-backed security turns the bank into an intermediary between the homebuyer and the investment industry. A bank can grant mortgages to its customers and then sell them at a discount for inclusion in an MBS. The bank records the sale as a plus on its balance sheet and loses nothing if the homebuyer defaults sometime down the road. This process works for all concerned as everyone does what they're supposed to do.
That is, the bank keeps to reasonable standards for granting mortgages; the homeowner keeps paying on time, and the credit rating agencies that review MBS perform due diligence. In order to be sold on the markets today, an MBS must be issued by a government-sponsored enterprise GSE or a private financial company.
The mortgages must have originated from a regulated and authorized financial institution. And the MBS must have received one of the top two ratings issued by an accredited credit rating agency.
Mortgage-backed securities loaded up with subprime loans played a central role in the financial crisis that began in and wiped out trillions of dollars in wealth. Mortgage-backed securities played a central role in the financial crisis that began in and went on to wipe out trillions of dollars in wealth, bring down Lehman Brothers , and roil the world financial markets.
In retrospect, it seems inevitable that the rapid increase in home prices and the growing demand for MBS would encourage banks to lower their lending standards and drive consumers to jump into the market at any cost. That was the beginning of the subprime MBS.
With Freddie Mac and Fannie Mae aggressively supporting the mortgage market, the quality of all mortgage-backed securities declined, and their ratings became meaningless. Then, in , housing prices peaked. Subprime borrowers started to default , which is the failure to repay a loan. As a result, the housing market began its long collapse. More people began walking away from their mortgages because their homes were worth less than their loans.
Even the conventional mortgages underpinning the MBS market saw steep declines in value. The avalanche of non-payments meant that many MBSs and collateralized debt obligations CDO based on pools of mortgages were vastly overvalued.
The losses piled up as institutional investors and banks tried and failed to unload bad MBS investments.
Credit tightened, causing many banks and financial institutions to teeter on the brink of insolvency. Lending was disrupted to the point that the entire economy was at risk of collapse. The U. Some of the measures of the bailout included the following:. On October 3, , the authority to initiate new financial commitments ceased, essentially ending any new bailouts under the TARP program.

So can you still afford to invest in these assets? In this article, we'll show you how you can use MBS to complement your other fixed-income assets. Mortgage-backed securities are debt obligations purchased from banks, mortgage companies, credit unions, and other financial institutions and then assembled into pools by a governmental, quasi-governmental or private entity.
These entities then sell the securities to investors. This process is illustrated below:. There are two types of MBS. The pass-through or participation certificate represents direct ownership in a pool of mortgages. You will get a pro-rata share of all principal and interest payments made into the pool as the issuer receives monthly payments from borrowers.
The mortgage pool will usually have a five-toyear maturity. However, the cash flow can change from month to month, depending on how many mortgages are paid off early. This is where the prepayment risk lies. When current interest rates decline, borrowers might refinance and prepay their loans. Investors must then try to find yields similar to their original investments in a lower, current-interest-rate environment.
Conversely, investors can face interest rate risks when interest rates go up. Borrowers will stay with their loans, leaving investors stuck with the lower yields in a rising current-interest rate environment. This is a pool of pass-through mortgages. There are several types of CMOs that are designed to reduce investors' prepayment risk.
In a sequential pay CMO , CMO issuers will distribute cash flow to bondholders from a series of classes, called tranches.
Each tranche holds mortgage-backed securities with similar maturity and cash flow patterns. Each tranche is different from the others within the CMO. For example, a CMO might have four tranches with mortgages that average two, five, seven and 20 years each. When the mortgage payments come in, the CMO issuer will first pay the stated coupon interest rate to the bondholders in each tranche.
Scheduled and unscheduled principal payments will go first to the investors in the first tranches. Once they are paid off, investors in later tranches will receive principal payments. The concept is to transfer the prepayment risk from one tranche to another. Some CMOs may have 50 or more interdependent tranches.
Therefore, you should understand the characteristics of the other tranches in the CMO before you invest. There are two types of tranches:. Fitch Ratings and others provide credit ratings as well as coupon rates and maturity dates for MBS.
You can buy MBS from several different issuers. Investment banks, financial institutions, and homebuilders issue private-label, mortgage-backed securities. Their creditworthiness and safety rating may be much lower than those of government agencies and government-sponsored enterprises. Freddie Mac is a federally regulated, government-sponsored enterprise that purchases mortgages from lenders across the country.
It then repackages them into securities that can be sold to investors in a wide variety of forms. Freddie Macs are not backed by the U.
