Essentially, mortgage backed securities (MBS) are the backbone of the American housing market. By turning groups of home loans into bundled securities that can be traded and sold, lenders can create more loans, keeping the mortgage market stable. Accordingly, the American financial system and housing market revolve around leveraging assets to access cash flow or capital (liquidity).
With this purpose, as banks lend money to financial institutions and individuals to buy property. These institutions will sell these mortgages to investment banks for a fee. The investment banks, called issuers, then bundle all these mortgages into a pool. In a nutshell, MBSs come as federal government backed loans, non-agency, and private-label. Let’s dive in and break down the basics of MBS investing.
Mortgage-backed securities (MBSs) sell on the secondary market or directly from the issuer. Government agencies like Freddie Mac, Fannie Mae, and Ginnie Mae offer MBSs with securitization, making them less risky for investors. In turn, Government agencies and providers use residential mortgage-backed securities to finance the housing market in America.
Since each pool contains thousands of different mortgage loans, the pools of mortgages become an investment product called mortgage backed securities or fixed-income securities, which is essentially ownership interest in the pool of mortgages.
Buying Mortgage Backed Securities
Buying MBSs involves varied levels of risk and return based on the volatility of loan defaults from each borrower’s home loan, called tranches. Investors choose tranches based on their risk appetite. The mortgages generate cash flows from the monthly payments of principal and interest the borrowers make.
These less risky cash flows are distributed to senior tranches first. The equity tranche is the highest risk level. (last to get payment.) The risk is the credit quality of borrowers. Lenders and underwriters assess the risk and return of their loans to offset default potential.
The To-Be-Announced market (TBA) allows MBS holders to trade securities before receiving all details regarding specific loans, making security trading efficient.
The History of Mortgage Backed Securities
The Great Recession and the housing crisis of 2008 woke America up. Lenders offering homeownership to unqualified borrowers through subprime loans weaken the housing market and devalue MBSs and related derivatives.
Like bonds, mortgage backed securities generate interest payments and principal payments. The steady stream of interest and payouts from underlying mortgages provide income for further investing. Since each tranche brings varying levels of risk, applicant vetting and loan approval processes are essential in ensuring that borrowers continue making their monthly mortgage payments.
Issuers and lenders learned a hard lesson during the financial crisis. Excessive issuance of subprime loans led to widespread defaults, causing turmoil in capital markets. The crisis highlighted the risks of poor credit quality and the need for better regulation of MBS issuance. Subsequently, borrowers with high credit risk, subprime loans, and non-agency MBS pose the most significant risk for investors.
To mitigate this risk, investors often diversify with MBS, stock market, or jump into the bond market, buying corporate bonds to balance investments and hedge their risk levels. Since fixed-income securities offer security with regular payments or coupons, their maturity date is very low risk to the investor. Considering the risk and cost of commercial property investment, it’s unsurprising that commercial mortgage securities are more challenging to trade than residential-backed mortgage securities (RMBS.)
The Role of the Government in Mortgage Backed Securities
Let’s discuss agency MBSs and the U.S. government’s role in MBSs. The U.S. Treasury supports them, ensuring their issuance throughout the market. The Federal Reserve (Fed) plays a vital role in stabilizing the MBS market because of the volume of loans it can purchase; these agencies balance interest rates.
Ginnie Mae (the Government National Mortgage Association) is foundationally anchored and backs up MBS comprised of FHA, VA, USDA, and other government-backed loans. Investors buying agency MBSs receive guaranteed repayment regardless of loan defaults from the underlying mortgages.
Although Fannie Mae and Freddie Mac are government-sponsored enterprises, their loans differ from Ginnie Mae. Investors face higher risks since the government doesn’t fully back conventional loans.
Non-agency or Private-Label (PLMBS) are issued by financial institutions without government backing, carrying higher credit risk. For investors, the bottom line is their return on investment. From conservative to risk-seeking investors, the bottom line is the ultimate payoff. Here’s how they get that ROI.
Making Money on MBS Investments
Investors looking for a quick return choose Pass-through securities, which allow investors to receive principal and interest payments directly from a pool of mortgages.
Collateralized Mortgage Obligations (CMOs) resemble layers on a cake. Each layer of the cake is a level of a tranche. Each layer or tranche has a payout schedule, and the rank depends on risk level. Investors receive payments based on priority. CMOs help manage prepayment risk and ensure timely payment to different classes of bondholders.
Interest Rates and Mortgage Backed Securities
Interest rates significantly impact MBS. Refinance affects MBS investors’ monthly payments. Since many homeowners pay off underlying mortgages when mortgage rates plunge, a balance in interest rates is crucial. Additionally, many homeowners with ARM loans take advantage of the lower interest rate by refinancing to a fixed-rate mortgage. Prepayment risk directly affects investor cash flows.
Mortgage Backed Securities and Mortgage Lenders
The U.S. mortgage market relies on homeowners prioritizing consistent loan repayment, and the credit quality of borrowers is essential in balancing interest rates throughout the economy. The consistent and steady payments from fixed-income MBSs create the capital for large banks, money markets, investors, and mutual funds. Additionally, when MBSs flow smoothly, the American economy is in sync with mortgage repayment, and the housing market is stable.
MBS are essential in the housing market because their liquidity allows lenders to issue more loans to Americans. Since pass-through securities offer straightforward payouts, they are ideal for low-risk investors. In contrast, CMOs attract strategic investors by providing a balance of control and payout.
