Federal Home Loan Mortgage Corp (FMCKN)

Freddie Mac has a simple job: it promises that if a homeowner stops paying their mortgage, Freddie Mac will step in and pay it off instead. Lenders charge borrowers a small extra fee for this promise, and that fee is where Freddie Mac makes its money.

Why Freddie Mac exists at all

Fifty years ago, the mortgage business worked very differently. A bank would lend money to a homebuyer, then hold that loan on its books for thirty years. But banks take in deposits that can be withdrawn on demand. If a bank lends out thirty-year money but has to give back deposits whenever someone asks, it runs into a problem: the money going out does not match the money coming in. Banks could not lend as much as they wanted, and lending was tight and expensive.

Freddie Mac was created to fix that. The idea was simple: let banks originate a mortgage, then sell that mortgage to Freddie Mac immediately. Freddie Mac takes the loan off the bank’s books and passes the risk along to investors by bundling mortgages into securities. The bank gets its money back and can lend again. Investors get a mortgage-backed security paying them a return. And Freddie Mac sits in the middle, charging a small fee for making sure that if the borrower stops paying, the investors still get their money.

This system has become the backbone of American housing credit. Almost no other developed country relies on it as heavily. The system works because the government promises that if things fall apart, it will stand behind Freddie Mac’s promises.

How the guarantee works and why it matters

A typical homeowner takes a thirty-year mortgage for $300,000 at 5% interest. That borrower pays about $1,610 per month. Out of that payment, about 25 to 40 cents goes to Freddie Mac as a guarantee fee. The borrower might not even notice it, because it is bundled into the rate the bank quotes.

Freddie Mac takes that fee—and collects the same fee on thousands of other mortgages—and builds up a guarantee reserve. If borrowers on Freddie Mac mortgages default, Freddie Mac pays the investor the full remaining balance. Over the past fifty years, Freddie Mac has paid out tens of billions of dollars to make good on defaults, especially during the housing crash of 2008. But the fees add up to far more than the losses, so the business is profitable even in bad years.

The government guarantee means Freddie Mac can borrow money and issue securities at rates almost as low as the government itself. That matters because it keeps the cost of mortgages down. If mortgages had to carry a truly private guarantee, they would cost borrowers more. Because the government is ultimately on the hook, the fee is lower, and borrowers benefit.

What Freddie Mac owns and controls

Freddie Mac does not own half the mortgages in America in the sense of holding them all on its balance sheet. Instead, it has a claim on them. When a borrower makes a payment, the payment goes to a servicer (usually a bank), which collects the money and sends it to Freddie Mac. Freddie Mac bundles the payments and sends them to the investors who bought the securities. Freddie Mac also holds a significant portfolio of mortgages and securities on its own books, earning the spread between what borrowers pay and what the company has to pay to borrow.

This portfolio is big—more than a trillion dollars—but it is secondary to the guarantee business. The guarantee business is Freddie Mac’s core: it is where the recurring fees come from, and it is what makes the company essential to the housing market.

The moat that nobody can break

Why does every bank use Freddie Mac? Why not just sell mortgages to private investors directly?

The answer is trust and cost. Investors will buy a Freddie Mac security at a much lower rate than they would buy the same mortgage from a private securitizer because they believe the government stands behind Freddie Mac. That lower rate translates to lower costs for borrowers, so banks steer their mortgages to Freddie Mac because it is the cheapest and easiest path. Freddie Mac then becomes the standard, and no competitor can displace it without offering a guarantee that is equally good and just as cheap. Only the government can do that.

This is called a network effect or, in older language, a moat. Once Freddie Mac is the market standard, banks and investors have no reason to switch, and new entrants have nowhere to begin. The government explicitly protects this moat: Congress will not let Freddie Mac fail, and Congress will not let a private competitor offer a better deal, because housing credit is a policy goal.

The only real competitor Freddie Mac has is Fannie Mae, another government-sponsored enterprise chartered for the exact same purpose. The two are structural twins, which is why they split the market roughly down the middle.

The problem with government ownership

In 2008, during the financial crisis, the government seized Freddie Mac to prevent it from collapsing. The government now owns the company, takes all its profits (after paying for operations and building small capital buffers), and makes all major decisions. Freddie Mac is in what is called conservatorship.

This arrangement means Freddie Mac is stable and profitable, but it also means that if you own a share of the equity, you might not see a return for a long time. The government controls whether Freddie Mac ever pays a dividend, and it currently does not. It also controls whether Freddie Mac will ever be returned to private ownership.

In a normal world, a company that guarantees more than a trillion dollars of mortgages and collects fees on all of them would be incredibly valuable. The shareholders would be rich. But because the government controls Freddie Mac, that value is locked up. Every dollar Freddie Mac earns goes to the Treasury, not to shareholders. This is why Freddie Mac preferred shares trade on obscure over-the-counter markets: they are illiquid and their value is deeply uncertain.

What could go wrong

The biggest risk is a severe housing downturn where a lot of borrowers stop paying their mortgages at once. If defaults spike, Freddie Mac’s losses rise, and the company might need government money to stay solvent. This happened in 2008–2009, and it cost the government nearly $200 billion to keep both Freddie Mac and Fannie Mae from failing. It could happen again.

A second risk is politics. Congress could decide to reform housing finance: to reduce Freddie Mac’s market share, to end the government guarantee, or to force the company to take more risk itself. Any major change would reshape the business.

A third risk is interest rates. Freddie Mac holds a big portfolio of mortgages. If rates spike, the value of those mortgages falls. The company hedges some of this risk, but not all of it. In a scenario where rates rise sharply and quickly, Freddie Mac could show large losses.

What to watch

If you are trying to understand Freddie Mac’s health and future, look at three things. First, watch the mortgage portfolio size and the fees it is collecting. Second, watch for any change in the government’s stance on when or whether to end the conservatorship. Third, monitor housing prices and unemployment: if borrowers are employed and house prices are holding up, Freddie Mac’s defaults stay low and profits hold. If either weakens, losses could spike.

The business itself—the guarantee, the fees, the central role in housing—is unassailable. The uncertainty is purely about ownership and policy. The company is not in danger. The shareholders are in limbo.
