Fannie Mae and Freddie Mac at Work in the Secondary Mortgage Market

by Michael Padhi, senior economic analyst

hen financing home purchases, consumers deal primarily with their lenders at the time of obtaining mortgage loans and through the loans’ term. Behind the scenes, though, is a very important secondary market for mortgages, in which banks and other mortgage originators sell claims to the mortgage payments to third parties. This secondary market provides valuable liquidity to mortgage originators and, in turn, benefits consumers by expanding the availability of mortgages.

Among the most active participants in the secondary market are Fannie Mae and Freddie Mac, both of which are government-sponsored enterprises. In gaining a better insight into the secondary mortgage market, it is important to understand the functions of these organizations, their unique relationship to the government and how commercial banks use their services.

Getting to know Fannie, Freddie and Ginnie

Fannie Mae and Freddie Mac are the popular names for the Federal National Mortgage Association (FNMA), chartered by Congress in 1938, and the Federal Home Loan Mortgage Corp. (FHLMC), chartered in 1970.

While both Fannie Mae and Freddie Mac currently have similar charters, congressional mandates and regulatory structure, they were originally formed with different focuses. Fannie Mae was formed to support the secondary market for Federal Housing Administration loans after the Great Depression, while Freddie Mac was created to provide a secondary market for conventional mortgages during the severe credit crunch of 1969–70 in the thrift industry. Today both Fannie Mae and Freddie Mac deal with all types of depository institutions and conventional as well as government-insured mortgage loans.

As government-sponsored enterprises, Fannie Mae and Freddie Mac — which are both publicly traded companies — receive explicit and implicit government subsidies. This mix of private and public involvement means that these organizations need to fulfill a public mission as well as provide investors with acceptable rates of return.

The federal government maintains its ties to Fannie Mae and Freddie Mac by providing various explicit subsidies: a $2.5 billion line of credit with the Treasury, exemption from registration with the Securities and Exchange Commission, and exemption from state and local income taxes.

Though obligations of Fannie Mae and Freddie Mac are not backed by the full faith and credit of the federal government, investors have indicated that they believe the government would provide any support necessary to keep these companies solvent because of their public sponsorship and mission. Fannie Mae and Freddie Mac benefit from this implicit guarantee through lower funding costs: Investors in their stock, general obligations and mortgage-backed securities (MBSs) accept lower rates of return in exchange for perceived lower risk.

Ginnie Mae, spun off from the FNMA in 1968 as the Government National Mortgage Association (GNMA), performs a similar role to Fannie Mae and Freddie Mac. It differs in two major ways, however: Ginnie Mae’s securities are backed by the full faith and credit of the U.S. government, and Ginnie Mae may purchase only federally insured Federal Housing Administration and Veterans Administration nonconventional mortgages.

Fannie, Freddie and the secondary mortgage market

Loan originators free up more funds for making additional loans by selling mortgages to Fannie Mae, Freddie

Mac and other purchasers in exchange for cash to possibly originate more loans. Fannie Mae and Freddie Mac either hold these purchased loans in their own portfolios or sell them in the secondary market in the form of MBSs, which are obligations to the security holder of the principal and interest payments from a pool of mortgages, less certain fees. The creation of securities based on a pool of underlying assets such as mortgages is known as “securitization.”

Fully private companies also buy mortgages and create MBSs backed by mortgages insured against credit loss through various credit enhancements. Private issuers of MBSs play an important role by securitizing conventional mortgages that do not qualify — also known as nonconforming mortgages — for Fannie Mae’s or Freddie Mac’s programs. Typically, a nonconforming mortgage’s loan amount exceeds the maximum limit that Fannie Mae or Freddie Mac may purchase, which is currently $275,000 for a single-unit home sold in the continental United States.

Relationship to commercial banks

Commercial banks interact extensively with Fannie Mae and Freddie Mac as mortgage sellers, mortgage servicers, and investors in Fannie Mae and Freddie Mac debt securities and, to a very limited degree, equity securities.

Banks as sellers of mortgages. Banks benefit from selling their mortgages to Fannie Mae or Freddie Mac by receiving liquid funds that can be used to originate more loans. Banks are also able to reduce the credit and prepayment risks of a mortgage that has an uncertain future cash flow in exchange for less risky assets, like MBSs. This management of risk allows the bank to free up some capital for lending or investing while meeting capital adequacy standards.

In 1999, commercial banks and their mortgage company affiliates sold to nonaffiliated purchasers $41.7 billion in mortgages originated by homebuyers in Southeastern metropolitan areas. Of this amount, 29.3 percent were sold to Fannie Mae, 24.5 percent to Freddie Mac and 22.7 percent to Ginnie Mae. (To obtain more data on sales of mortgages, see to download Home Mortgage Disclosure Act reports.)

Banks as servicers of sold mortgages. The servicing rights of mortgages sold to Fannie Mae and Freddie Mac can be retained by the originators, which have the facilities and the relationships with borrowers that allow them to service at a profit. Servicing a loan includes collecting the principal and interest from borrowers, monitoring delinquencies and executing necessary foreclosures. Contracts with Fannie Mae and Freddie Mac make up 62.5 percent of the outstanding principal of serviced mortgages by commercial banks. Ginnie Mae contracts constitute 19.2 percent.

The servicing agreements place the obligation to cover borrower defaults on either the servicer or the securitizer. Only a small percentage of Freddie Mac and Fannie Mae servicing agreements with U.S. commercial banks place this obligation on the bank servicers (4.2 percent), showing that an important motive for banks to sell mortgages is to reduce credit risk.

Since the mid-1990s, commercial banks have securitized mortgages to overcome liquidity constraints, allowing them to greatly increase mortgage originations. The percentage of banks’ single-family mortgage loans to total assets has remained mostly constant at about 15 percent during this time even though total mortgage originations significantly increased, demonstrating the usefulness of securitization in overcoming liquidity constraints (see the chart ).
