Securitization – the bundling of bank loans to create tradeable bonds – started in the mortgage industry in the 1970s, when Government Sponsored Enterprises (GSEs) began to pool relatively safe, conventional, "conforming" or "prime" mortgages, create "mortgage-backed securities" (MBS) from the pool, sell them to ...
The first mortgage-backed security (MBS) was issued in 1968. Thereafter, the MBS market grew rapidly with outstanding issuances exceeding $9 trillion by 2010.
Improved Liquidity and Risk Argument
In this way, an MBS is a liquid product. Mortgage-backed securities also reduce risk to the bank. Whenever a bank makes a mortgage loan, it assumes risk of non-payment (default). If it sells the loan, it can transfer risk to the buyer, which is normally an investment bank.
The purchase activity began on January 5, 2009 and continued through March 31, 2010. How were MBS purchases conducted? MBS were purchased in the secondary market on a daily basis, with the primary dealers as counterparties.
Most mortgage-backed securities are issued by Fannie Mae, Freddie Mac and Ginnie Mae. These are government-sponsored enterprises that buy mortgage loans. These companies were designed to make homeownership more accessible to consumers.
Ultimately, as house prices declined nationwide and mortgage defaults began rising, the value of all the mortgage-backed securities deteriorated. The rise in defaults, by undermining the value of trillions of dollars of mortgage-backed securities, severely disrupted the securitization funding mechanism itself.
Lewis Ranieri is considered by some critics as a pioneer who revolutionized the mortgage industry and the way that mortgages were packaged and sold. 7 He played a key role in the creation of the mortgage-backed securities market.
The Federal Reserve is the single largest agency MBS investor through its large-scale asset purchase program, with total holdings of $2.5 trillion as of October 2021.
When the COVID crisis hit in March 2020, the Fed decided to reinstate its 2008 financial crisis rescue plan. It resumed purchasing MBS as well as Treasury notes and bonds. By the time it stopped its purchases in the spring of 2022, it owned $2.7 trillion in MBS.
The institution that buys the mortgage loan pools the mortgage with other mortgages having similar characteristics, such as interest rates and maturities. It then sells these mortgage-backed securities to interested investors. It uses the funds from the sale to buy more securities and float more MBS in the open market.
Mortgage-backed securities are still bought and sold today. There is a market for them again simply because people generally pay their mortgages if they can. The Fed still owns a huge chunk of the market for MBSs, but it is gradually selling off its holdings.
More complicated mortgage-backed securities, known as collateralized mortgage obligations (CMOs) or real estate mortgage investment conduits (REMICs), consist of multiple classes of securities designed to appeal to investors with different investment objectives and risk tolerances.
If the Fed sells mortgage securities that pay low rates at a time when prevailing rates are much higher, it will incur big financial losses that reduce the funds the central bank returns to the Treasury.
Many analysts blame the recent financial crisis on the increased use of securitisation, which, they argue, weakened the credit standards of banks, encouraged them to take excessive risks and, subsequently, pass those risks on to other investors.
To combat this, in 1970, Ginnie Mae developed the very first mortgage-backed security (MBS), which allowed for many loans to be pooled and used as collateral in a security that could be sold in the secondary market.
When mortgage rates go up, the price of MBS goes down by a greater amount than the price goes up when rates go down by the same amount. As rates fall, MBS prices go up less (compared to other bonds) because of refinancing, where the maturity of mortgages becomes shorter.
The Fed currently holds about $2.6 trillion of MBS as part of its roughly $8 trillion securities portfolio. That is about a quarter of the total MBS market, what George referred to as an "enormous" share that raises questions about the appropriate extent of the central bank's presence.
The biggest buyer was the Fed itself, which purchased swaths of the bond markets to stimulate the economy during the pandemic. Its holdings of mortgage-backed securities roughly doubled from before the pandemic to $2.7 trillion.
Credit risk is one significant risk, which refers to the risk that borrowers will default on their mortgages, reducing the cash flows to investors. If a large number of borrowers default, investors may lose a significant portion of their investment.
Fannie Mae creates MBS that represent beneficial ownership interests in a pool of mortgage loans secured by multifamily (5 or more units) residential properties.
The Great Recession refers to the economic downturn from 2007 to 2009 after the bursting of the U.S. housing bubble and the global financial crisis. The Great Recession was the most severe economic recession in the United States since the Great Depression of the 1930s.
Attractive yields
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.
What Is A Mortgage REIT? Mortgage REITs, or mREITs, are investments in purchased or originated mortgages and mortgage-backed securities (MBS) that earn income from the interest paid on those assets.
MBSs are created by companies called aggregators, including government-sponsored entities such as Fannie Mae or Freddie Mac. They buy loans from lenders, including big banks, and structure them into a mortgage-backed security.
