Freddie Mac buys mortgages from lenders, bundles them into securities, and guarantees investors get paid, which keeps money flowing for home loans.
Freddie Mac is one of the two big companies that quietly keep the American mortgage machine running. It buys home loans from banks and other lenders, bundles thousands of them together into tradable securities, and guarantees that investors who buy those securities will get paid even if some borrowers default. That guarantee is the heart of the business: it turns a pile of individual mortgages into something pension funds and bond investors are happy to hold.
Here's the basic problem it solves. A bank that writes a 30-year mortgage has its money tied up for decades, which limits how many more loans it can make. Freddie Mac steps in, buys the loan, and frees the bank to lend again. Lenders pay Freddie Mac a fee for that guarantee, and Freddie Mac keeps a slice of the interest it collects. Multiply that thin margin across trillions of dollars of mortgages, and it adds up to a large, steady business. Freddie Mac works alongside its bigger sibling Fannie Mae, and together the two dominate the market for conventional home loans. They were chartered by Congress but are private, shareholder-owned companies, and since 2008 they have been under government conservatorship after the housing crash nearly wiped them out. That arrangement is the company's central fact of life: it is profitable and systemically important, but its future — whether it gets released from government control, and on what terms — is a political and regulatory question, not a business one.
The company also buys and guarantees loans on apartment buildings, not just single-family homes, which gives it a second steady stream of guarantee fees, especially in a rental market where demand for multifamily housing has been strong. Its main risk is the same one that broke it in 2008: a deep housing downturn that produces a wave of defaults. The government backstop blunts that risk for investors but not for shareholders, whose upside depends on decisions made in Washington as much as on the housing market.
