Individual bundles represent security similar to bonds and are tradeable in the secondary market. Mortgage-Backed Securities (MBS) play a significant role in the financial world, shaping investment strategies. These securities are instrumental in the housing market and impact both institutional and individual investors. Credit risk of the issuer itself may also be a factor, depending on the legal structure and entity that retains ownership of the underlying mortgages. Mortgage-backed securities reduce lenders’ risk, encouraging them to originate and offer loans, and providing them with the capital to do so. Their presence helps keep money flowing throughout the financial system, keeping it running smoothly.
As these prepayments occur, the amount of principal retained in the bond declines faster than originally projected, shortening the average life of the bond by returning principal prematurely to the bondholder. Because this usually happens when interest rates are falling, the reinvestment opportunities can be less attractive. Prepayment risk can be reduced when the investment pools a large number of mortgages, since each mortgage prepayment would have a reduced effect on the total pool. Mortgage-backed securities typically offer yields that are higher than government bonds. Securities with higher coupons offer the potential for greater returns but carry increased credit and prepayment risk, meaning the realized yield could be lower than initially expected.
They then bundle hundreds or thousands of these loans into mortgage-backed securities. With MBS, investors benefit from the mortgage business without needing to buy or sell home loans themselves. We’ll help you learn more about what mortgage-backed securities are and how these investments work.
Defragmenting Markets: Evidence from Agency MBS
These complicated investments are constructed by slicing a pool of mortgages into similar risk categories, known as tranches. The least risky tranches have more certain cash flows and a lower degree of exposure to default risk, while riskier tranches have more uncertain cash flows and greater exposure to default risk. However, the elevated level of risk is compensated with higher interest rates, which are attractive to some investors. In short, the mortgage-backed security meaning depicts it as a bond-like security created by bundling mortgages. In this market, banks connect property buyers, usually clients seeking home mortgage loans, and investors. As a result, the borrower’s monthly payment against the mortgage will ultimately reach investors.
Commercial mortgage-backed securities (CMBS) vs. residential mortgage-backed security (RMBS)
- Selling mortgages to the secondary market allows banks to have the capital to continue offering loans to new homeowners, according to Ginnie Mae.
- In the 2020s, most MBS have the backing of the U.S. government; these are called agency MBS.
- They are a type of asset-backed security that is secured by a collection of mortgages.
- A strong housing market often bolsters a strong economy and helps employ many workers.
- At the same time, the impact of certain events like default in payment, interest rate fluctuations, and prepayment will fall on the investors, not the intermediary banks.
By pooling so many mortgages, there’s less investment risk with MBS if someone defaults on their mortgage. Prepayments can be either voluntary, such mortgage backed securities meaning as when borrowers refinance or relocate, or involuntary from defaults. Refinancing is the most significant source of prepayment, as borrowers can pay off their remaining balance at par without penalty when market interest rates decline. This makes MBS callable securities, limiting their price appreciation potential and resulting in negative convexity. The weighted average coupon (WAC) can estimate the prepayment characteristics of a pool of underlying mortgages. An MBS is a bond that is collateralised by a mortgage or a collection of mortgages and traded on the secondary market.
- The Federal Reserve is the single largest holder, followed by GSEs like Fannie Mae and Freddie Mac.
- The senior tranche is the first to soak up cash flows and the last to absorb loan defaults or missed payments.
- Before MBSs, only banks had significant enough deposits to make long-term loans or the capacity to wait until these loans were repaid decades later.
We operate in 14 countries and manage CHF 16.3 billion in assets for our clients as at 31 December 2024. As of 31 January 2024, Fund Management Services were successfully transferred to the Carne Group. Private-label MBSs comprised more than 50% of the mortgage finance market in 2006.

Investing in MBS comes with advantages and disadvantages, which will vary depending on the security and entity you invest in.
What is the relationship between a mortgage-backed security and a bank?
Derivatives, on the other hand, are financial instruments whose value is derived from the value of an underlying asset, index, or interest rate. To be sold on the markets today, an MBS must be issued by a GSE or a private financial company, and the MBS must have received one of the top two ratings issued by an accredited credit rating agency. Non-agency MBS, meanwhile, are issued by private financial institutions and are not guaranteed. Instead, securities are grouped by seniority and sold to investors with different appetites for risk.
Mortgage-Backed Securities and the Financial Crisis of 2007 to 2008
Investment banks created more complicated investment products to attract customers. For example, they developed collateralized debt obligations (CDOs) which could include any type of loan. To the investor, these products function like an MBS, even though they may or may not contain mortgages. Mortgage-backed securities are a specific type of asset-backed security. In other words, they’re a kind of bond that’s backed by real estate like a residential home.
MBSs are also sensitive to changes in interest rates on loans and mortgages. If interest rates rise, fewer people will take out mortgages, causing the housing market to decline. For investors, mortgage-backed securities have some advantages over other securities. They pay a fixed interest rate that is usually higher than U.S. government bonds. Moreover, they typically offer monthly payouts, while bonds offer a single lump-sum payout at maturity. In what follows, we take you through the details of what these investments are, why they exist, and their place in the markets of the 2020s.
How are Mortgage-Backed Securities Created?
We all grew up with the idea that banks make loans and then hold those loans until they mature. But the reality is that there’s a high chance your lender is selling the loan into what’s known as the secondary mortgage market. Here, aggregators buy and sell mortgages, finding the right kind of mortgages for the security they want to create and sell to investors. If your loan servicer changes soon after you’ve gotten a mortgage, it’s probably because the loan’s been packaged into a mortgage-backed security.
This structure was perceived to mitigate the impact of defaults on any single investor or the issuing bank. Collateralized mortgage obligations are organized by slicing a pool of mortgages into similar risk profiles known as tranches. Tranches are given different credit ratings and generally have different principal balances, interest rates, maturity dates, and the potential for repayment defaults.
The payment individual investors receive is proportional to their investment. This is the risk that homeowners will decide not to make prepayments on their mortgages to the extent initially expected. This usually occurs when interest rates are rising, which gives homeowners little incentive to refinance their fixed-rate mortgages.
Since so many investors, pension funds, and financial institutions owned mortgage-backed securities, everyone took losses. One of the reasons behind the ease of the loan availing process is the evolution of MBS. Bank provides loans to Ben, and they sell this mortgage to government-backed entities like Fannie Mae or Freddie Mac supporting the United States home finance system.
Risky lending practices, subprime mortgages packaged into MBS, and complex financial instruments contributed to the housing market collapse. The widespread default on these mortgages led to significant losses for investors and financial institutions, triggering a global financial crisis. This type of security is not backed by government entities and is instead issued by private entities/financial institutions.
