Mortgage-Backed Securities - What Does It Means?

Mortgage-backed securities (MBS) are an alternative worth considering if you’re trying to broaden your investment portfolio. Mortgage-backed securities (MBS) are bundles of loans that have been purchased from mortgage-issuing banks and then resold to investors.

To profit from the mortgage market, investors might acquire mortgage-backed securities (MBS) instead of individual mortgage loans. Please read on if you are interested in understanding the ins and outs of mortgage-backed securities.

Definition of Mortgage-Backed Securities

MBSs, or mortgage-backed securities, are investments backed by a pool of mortgages purchased from issuing banks. On the secondary market, mortgage-backed securities are traded. An MBS is a mortgage-backed security. Mortgage funding and house loan procedures have been more streamlined as a result of asset-backed securities.

Fannie Mae, Freddie Mac, and Ginnie Mae issue the vast majority of mortgage-backed securities. These companies are backed by the government and buy mortgages. These institutions were established to lower the threshold for people to become homeowners.

Fannie Mae, Freddie Mac, and Ginnie Mae are private firms, not government agencies, but they nonetheless regulate the financial sector.

Background on MBSs (Mortgage-Backed Securities)

The Housing and Urban Development Act was signed into law by President Lyndon B. Johnson in 1968. In the same year that this law was passed, Ginnie Mae was founded to guarantee the first MBS. The idea of MBSs was to facilitate the sale of mortgages by financial institutions, freeing up capital for further consumer lending. Mortgage-backed securities opened the door for non-banks to participate in the mortgage market.

In 2010, the market was worth more than $9 trillion, demonstrating rapid expansion. Bonds secured by the regular repayment of mortgage principal and interest were a huge success with a previously untapped group of investors.

The issue was that MBSs lacked the same oversight as traditional financial instruments like banks and financial institutions. Many financial institutions started accepting borrowers with lower credit scores and incomes as a means of staying in business. Because of this, the 2008 economic crisis was exacerbated. The government increased banking industry rules when the housing market stabilized.

Investors in MBSs are now required to receive mandatory disclosures and other forms of regulation-mandated information. The financial crisis also highlighted the significance of using only high-quality assets in mortgage-backed securities.

What Are the Functions of Mortgage Backed Securities?

The bank mediates the relationship between the homeowners and the investors in MBSs. Banks typically close on and resell single-family mortgages as conventional loans. They are then packaged as a mortgage-backed security with other loans of a similar nature. The mortgages are subsequently placed on the bond market and sold by the banks.

To learn more about MBSs, it can be instructive to examine the steps used by a bank or other financial institution when issuing a mortgage.

To illustrate, let’s imagine you’re interested in purchasing a new house. You would start the mortgage process by applying at a bank. In exchange for loaning you money, the bank would charge you interest, which may be either set or variable. They could keep the mortgage and keep accruing interest and principal payments forever. To free up some capital, the bank might also sell the interest and principal to a group of investors. The bank maintains its revenue stream through creating and maintaining mortgages.

The bank will combine your mortgage with hundreds, if not thousands, of others to make a mortgage-backed security. These loans are packaged together as a bond and sold to an investment bank. The loans are subsequently sorted by the investment bank and sold to other investors. The inclusion of a loan in a mortgage-backed instrument is determined by its characteristics and risk profile.

Mortgage Interest Rate Effects

Mortgage-backed securities (MBSs) trading also has a substantial effect on mortgage interest rates. Bond yields are influenced by mortgage characteristics and credit profiles, which in turn affects mortgage rates.

Pass-throughs and collateral mortgage obligations (CMOs) are the two most common forms of mortgage-backed securities. Let’s have a look at a brief summary of each.


The simplest type of mortgage-backed security is called a “pass-through.” Investors get their cut of the principle and interest that homeowners pay each month.

In other words, the principal and interest are both returned to the investors on a monthly basis. However, homeowners shouldn’t expect any changes to their monthly payments as a result of a mortgage pass-through.

Mortgage Collateral Obligations

Mortgage pass-throughs are simpler than collateralized mortgage obligations (CMOs). Each mortgage pool in a CMO will have its own tranche with its own interest rate, risk profile, and maturity date. Mortgage-backed security interest rates are established based on the credit ratings assigned to the various tranches.

Should You Invest in Mortgage-Backed Securities?

Prior to 2008, the Federal Reserve’s effect on mortgage rates was minimal at best. To boost the economy, bring down mortgage interest rates, and provide market liquidity, the Fed started purchasing MBSs directly around this time. For more than a decade, the Fed amassed more than $2 trillion in MBS holdings through this approach. In recent months, however, the Fed has decided to gradually withdraw from the MBS market by suspending its formerly steady asset purchases.

Since housing costs make up a sizable portion of total economic input, the low mortgage rates made possible by the acquisition of these MBSs were a boon to the economy. But lower interest rates led to higher property values, which is counterproductive right now. The Fed plans to fight inflation by stopping the acquisition of MBSs.

Mortgage-Backed Securities: Pros and Cons for Investors

The benefits and drawbacks of investing in MBSs will vary based on the specific securities and the entity in which the investment is made.

Make sure a mortgage-backed security is a good fit for your investment goals and risk tolerance before making any purchases. Some of the benefits and drawbacks of investing in these assets are outlined below.

Mortgage-Backed Securities’ Pros

Among the many benefits of purchasing an MBS are the following:

Because MBSs are typically fixed-rate loans with prepayment penalties, they are a secure investment option.
Investment returns on MBSs are often more attractive than those on U.S. government bonds. The largest potential benefits are found in securities with greater coupons.
Government-backed mortgage-backed securities (MBSs) are considered to have a low credit risk.
Negatives of Mortgage-Backed Securities

The following are some potential risks associated with purchasing an MBS:

The possibility always exists that borrowers will pay off their mortgages sooner than projected by making larger monthly payments. They could also refinance their mortgage, which is a popular option when interest rates drop.
Because of the potential for a decline in value when interest rates rise, MBSs are not immune to interest rate risk.
Investors run the risk of losing money due to credit and default if borrowers do not pay back their loans’ interest and principal. The strength of the market and the timing of the loan’s issuance determine the degree of risk.
The risk of an extension arises from the possibility that mortgage prepayments will not be made by borrowers. Since the principal has decreased, the coupon on the security may be lower than planned. This is usual once interest rates on Treasuries begin to rise.

The Bottom Line

Over the years, mortgage-backed securities have undergone significant change. MBSs are now a considerably more secure investment option than they were in the past because of tighter financial sector regulation.

The reality, however, is that no investment is 100% safe. You should always know what you’re getting into before putting money into anything.
