How did mortgage-backed securities contribute to the financial crisis of 2007 & 2008? Banks lost money on mortgages they still held.

Traditional lenders were forced to lower their credit standards to compete for home loan business. At the same time, the U.S. government was pressuring lending institutions to extend mortgage financing to higher credit risk borrowers. This led to the creation of massive amounts of mortgages with a high risk of default.

Securitization of home mortgages fueled excessive risk-taking throughout the financial sector, from mortgage originators to Wall Street banks. When U.S. housing prices began to fall, mortgage delinquencies soared, leaving Wall Street banks with enormous losses on their mortgage-backed securities.

Which of the following best describes a mortgage-backed security? A mortgage-backed security is a combination, or bundle, of mortgages. The new security is then available for resale in secondary markets.

Mortgage-backed security (MBS) is a variation of an asset-backed security but one that is formed by pooling together mortgages exclusively. The investor who buys a mortgage-backed security is essentially lending money to home buyers. An MBS can be bought and sold through a broker.

The four major classes of mortgage-backed securities are mortgage-backed bonds (MBBs), mortgage pass-through securities (MPTs), mortgage pay-through bonds (MPTBs) and collateralized mortgage obligations (CMOs) [for our class, you do not need to be familiar with MPTBS].

An asset-backed security (ABS) is a type of financial investment that is collateralized by an underlying pool of assets—usually ones that generate a cash flow from debt, such as loans, leases, credit card balances, or receivables.

Nobody coerces a borrower into taking out a mortgage loan, just as no financial institution is legally obligated to make additional loans and no investor is forced to purchase an MBS. The MBS allows investors to seek a return, lets banks reduce risk and gives borrowers the chance to buy homes through free contracts.

Mortgage-backed securities can be an appropriate choice for bond investors seeking a monthly cash flow, higher yields than Treasuries, generally high credit ratings, and geographic diversification.

Hedge funds, banks, and insurance companies caused the subprime mortgage crisis. Hedge funds and banks created mortgage-backed securities. When the Federal Reserve raised the federal funds rate, it sent adjustable mortgage interest rates skyrocketing. As a result, home prices plummeted, and borrowers defaulted.

However, if a significant number of mortgagors begin to default on their loans, the mortgagee may default on their MBS. This level of default will cause investors to suffer, demonstrating the need for some form of insurance or a guarantee. Depending on the issuer, an MBS may or may not be guaranteed.

When MBS prices drop, lenders raise interest rates, and when prices rise, they drop their rates. In general, lenders are quicker to respond to price drops than increases, because lending at below-market rates costs them money.

A collateralized mortgage obligation, or CMO, is a type of MBS in which mortgages are bundled together and sold as one investment, ordered by maturity and level of risk. A mortgage-backed security, or an MBS, is a kind of asset-backed security that represents the amount of interest in a pool of mortgage loans.

A CMO is a type of mortgage-backed security (MBS) with separate pools of pass-through security mortgages that contain varying classes of holders and maturities (tranches).

Collateralized Debt Obligations. Like CMOs, collateralized debt obligations (CDOs) consist of a group of loans bundled together and sold as an investment vehicle. However, whereas CMOs only contain mortgages, CDOs contain a range of loans such as car loans, credit cards, commercial loans, and even mortgages.

They are guaranteed to receive the full return of face-value principal even if the underlying borrowers default on their loans. To the extent that private-label CMOs use agency mortgage pass-through securities as collateral, their agency collateral carries the respective agency’s guarantees.

Some private institutions such as subsidiaries of investment banks, financial institutions and home builders also issue mortgage backed securities. “Private label” CMOs issued by financial institutions are often collateralized with specialized types of loans, loan pools, letters of credit or credit enhancements.

while CDOs are private labeled. The CMO is a little easier to understand as the cash flow it provides is from a specific pool of mortgages while the CDO cash flows can be backed by automobile loans, credit card loans, commercial loans and even some tranches from a CMO.

CMO bonds are highly rated; because they are often based on government-backed mortgages and other top-grade loans, there is little default risk involved. CMO bonds are issued by the Federal Home Loan Mortgage Corporation (FHLMC), the federally sponsored corporation that also issues Freddie Mac pass-throughs.

Investors in CMOs wish to be protected from prepayment risk as well as credit risk. This prepayment risk cannot be removed, but can be reallocated between CMO tranches so that some tranches have some protection against this risk, whereas other tranches will absorb more of this risk.

CMOs are very complicated fixed-income investments that carry significant risks, including prepayment and extension risk, as well as market risk.

Because they are a type of security sold to investors, CMOs are usually created by investment banks.
