Not only does securitization of mortgages provide increased liquidity for investors, lenders and borrowers, it also offers a way to support the housing market, which is one of the largest engines of economic growth in the U.S. A strong housing market often bolsters a strong economy and helps employ many workers. In the case of CMOs, when prepayments occur more frequently than expected, the average life of a security is shorter than originally estimated. CMOs take the cash flow from pass-throughs and segregate it into different bond classes known as tranches, which provide a time frame, or window, during which repayment is expected. The tranches prioritize the distribution of principal payments among various classes and serve as a series of maturities over the life of the mortgage pool. CMOs are repackaged pass-through mortgage-backed securities with the cash flows directed in a prioritized order based on the structure of the bond.

Issuers must also provide investors with disclosures including sharing information about their risks. Government-sponsored entities such as Fannie Mae and Freddie Mac play a significant role in the MBS market. They purchase mortgages from lenders, package them into securities, and guarantee payments to investors, thus providing liquidity to the housing market. The implicit and sometimes explicit government support provides a level of confidence in MBS, making them attractive to investors. A collateralized mortgage obligation — usually referred to as a “CMO” — is a bit more complex than a pass-through.

The Role of Government in MBS

Firstly, not only does securitization of mortgages provide increased liquidity for investors, lenders, and borrowers, but it also offers a way to support the housing market. A strong housing market often bolsters a strong economy and helps drive growth. Today, an MBS can only be issued by a government-sponsored enterprise (GSE) or a private financial company to be sold on the markets. In addition, the mortgages have to originate from a regulated and authorized financial institution. Moreover, the MBS must have received one of the top two ratings issued by an accredited credit rating agency.

Who Sells Mortgage-Backed Securities?

Fannie Mae and Freddie Mac do not have the same guaranteed backing, but they can borrow directly from the Treasury when needed. After the housing crisis, the U.S. government increased regulations in several areas, including residential MBSs. In response to the new requirements, there are fewer registered MBSs other than the ones offered by Fannie Mae and Freddie Mac. The federal government regulated banks to make sure their depositors were protected, but those rules didn’t apply to MBSs and mortgage brokers. President Lyndon Johnson paved the way for modern-day mortgage-backed securities when he authorized the 1968 Housing and Urban Development Act, which also created Ginnie Mae. Johnson wanted to give banks the ability to sell off mortgages, which would free up funds to lend to more homeowners.

Conversely, if thousands of people cannot make their mortgage payments and go into foreclosure, the CMO mortgage backed securities meaning loses money and cannot pay the investor. Fannie Mae and Freddie Mac are both publicly traded GSEs, with their primary difference being that Fannie Mae buys mortgage loans from major retail or commercial banks, while Freddie Mac gets its loans from smaller banks. Mortgage-backed security and mortgage bond are the terms that sound and seem similar and mostly, amateur investors mistakenly use them synonymously.

1. The least risky tranches have more certain cash flows and a lower degree of exposure to default risk.
2. This risk can be particularly significant for investors in long-term MBS, as changes in interest rates can have a greater impact on the value of longer-term securities.
3. Their presence helps keep money flowing throughout the financial system, keeping it running smoothly.
4. However, amid Covid 19 pandemic, the Federal Reserve currently holds a large portion of the MBSs to protect the economy.
5. While mortgage-backed securities offer several benefits to investors, they also carry several risks.
6. In other words, they’re a kind of bond that’s backed by real estate like a residential home.

In short, many borrowers got into loan obligations that they could not afford. A mortgage-backed security (MBS) is a type of asset-backed security (an “instrument”) which is secured by a mortgage or collection of mortgages. The mortgages are aggregated and sold to a group of individuals (a government agency or investment bank) that securitizes, or packages, the loans together into a security that investors can buy. A collateralized mortgage obligation (CMO) is a financial product backed by a pool of mortgages bundled together and sold as an investment. CMOs generate cash flow as borrowers repay the mortgages that act as collateral on these securities.

1. If interest rates rise, fewer people will take out mortgages, causing the housing market to decline.
2. As each homeowner pays off their loans, the loan payments provide a steady income stream for investors who hold MBS.
3. The securitization process involves converting the cash flows from a pool of mortgages into securities that can be sold to investors.
4. The widespread default on these mortgages led to significant losses for investors and financial institutions, triggering a global financial crisis.
5. Around the time CDOs were created, investment banks also developed a more complex version of the mortgage-backed security, the collateralized mortgage obligation (CMOs).
6. Mortgage-backed securities (MBS) are investment products created by pooling individual mortgages together and selling them to investors.

This is related to duration risk, which arises from the sensitivity of MBS prices to changes in interest rates. MBS typically have extended maturities and pay fixed coupons, resulting in high duration and significant price sensitivity to interest rate movements. However, unlike traditional fixed-income securities, the duration of MBS is not fixed but remains uncertain because of the potential for borrowers to prepay their loans at any time. Mortgage-backed securities are also considered relatively low-risk, given the government backing for most of them. If an MBS is guaranteed by the federal government, investors do not have to absorb the costs of a borrower’s default.

Ginnie Mae’s goal is to ensure affordable home loans for underserved consumers in the mortgage market. Typical buyers of MBS include individual investors, corporations, and institutional investors. Two primary types of MBSs are pass-throughs and collateralized mortgage obligations (CMO). An MBS is traded on the secondary market and can be bought and sold through a broker. Government agencies or sponsored enterprises, Central banks, and private investment banks can issue MBSs.

Each rating determines the amount of principal and interest each tranche receives. Fannie Mae and Freddie Mac were bailed out by the U.S. government following the financial crisis and delisted from the NYSE. Today, Fannie Mae’s and Freddie Mac’s shares are traded over-the-counter (OTC), meaning you can’t buy them on a major stock exchange. While entities such as Fannie Mae and Freddie Mac can issue and guarantee mortgage-backed securities, the guarantee provided by Freddie Mac is not supported by the government. Lewis S. Ranieri, often hailed as the father of mortgage-backed securities, along with Anthony J., is credited with founding mortgage-backed securities.
