Ellington Financial Inc. (EFC-PC)

Ellington Financial is a company that borrows money, buys mortgages and mortgage securities, collects the interest, and passes most of the money back to shareholders. That is the whole business. No products, no employees making things, no stores or services. Just: borrow cheap, lend at higher rates, keep the difference, and pay it out.

The company was started in 2004 and is structured as a mortgage REIT. REIT is short for real estate investment trust. The idea is simple: a REIT owns real estate or real-estate loans, collects the income from them, and must give away at least 90 percent of the money it makes to the people who own shares. In return, the REIT itself pays almost no taxes. The shareholders pay the taxes instead. That is the deal.

Ellington’s real estate is mortgages—loans people owe on houses and commercial buildings. The company buys these mortgages or the securities that represent them, holds them, and collects the monthly payments. It pays for them by borrowing money at lower rates than the mortgages pay. This spread—the gap between what it earns and what it costs to borrow—is the profit.

Why the spread matters more than anything else

When a mortgage pays 5 percent interest and the company borrows money at 3 percent, the 2 percent spread is what the shareholders get. Multiply that by a huge balance sheet, and it becomes real money. But the moment rates change, everything falls apart. If the company has to refinance its borrowing at 5 percent, the spread vanishes. And if interest rates rise, all the mortgages and mortgage securities it already owns lose value immediately, because a new mortgage paying 5 percent looks bad when the market is offering 7 percent on new ones.

This is the iron law of mortgage REITs: they make money in low-rate environments, and they get crushed in high-rate environments. The company in 2021 and early 2022, when rates were near zero, was a machine that printed money for shareholders. By 2023, when the Federal Reserve jacked up rates to fight inflation, the same company saw the value of its holdings cut in half. Shareholders who expected steady high payouts suddenly saw cuts.

The origination side

Ellington does not just buy mortgages in the market. It also makes mortgages—originates them. The company has people who take applications, underwrite loans, and close them. It charges a fee for doing this, usually one to two percent of the loan amount. Then it either keeps the mortgage and collects the interest, or sells it off and takes the fee.

In booming years like 2020 and 2021, when people were refinancing their houses like crazy because rates were so low, origination was a gold mine. The company made thousands of mortgages and pocketed fees on all of them. Then the boom ended. As rates climbed, refinancing stopped. People who already had mortgages stayed put. New originations slowed to a trickle. That fee income dried up.

How lending on borrowed money creates trouble

The leverage—borrowing to buy mortgages—is the amplifier. If the spread is 2 percent and you are leveraged four-to-one (four dollars borrowed for every dollar owned), your return on the shareholder’s equity is close to 8 percent. That looks great. But it also means that if the spread narrows to one percent, the return is halved. And if the spread turns negative—if you are paying more to borrow than you are earning on the mortgages—you are bleeding out.

When rates rise fast and spreads compress, mortgage REITs can get trapped. They owe money to the banks that lend to them via something called the repo market, a form of short-term borrowing. In a crisis, the repo market can seize up. Lenders can refuse to roll over the loans, and the REIT is forced to sell assets into a bad market, crystallizing losses. The company’s relationship with Ellington Management Group, its parent, helps here—the parent can inject capital if needed—but that is a backstop, not a permanent solution.

The payout trap

A mortgage REIT almost has to distribute its earnings. It is required to give away 90 percent of taxable income. But taxable income and economic profit are not the same thing. A REIT can have great taxable income in year one, pay it all out to shareholders, and then discover in year two that the value of its assets fell in the meantime. The shareholder got paid, but his share of the company is worth less. That is what happened to many mortgage REITs in 2023.

This creates a dangerous psychology. Shareholders buy the stock for the yield—the monthly or quarterly payout. When the payout gets cut, they sell, and the stock tanks. Management knows this and sometimes fights hard to keep the payout stable even when economic conditions are deteriorating. The result is that the payout can mask the real health of the business.

What determines whether Ellington survives good times and bad

Three things matter. The first is the credit quality of the mortgages. If the mortgages are sound and people keep paying, the REIT earns its income reliably. If defaults spike—if people stop paying—the REIT takes losses. Ellington has generally done well here; its mortgage portfolios have had low default rates. But a severe recession, a spike in unemployment, or a crash in house prices could change that.

The second is the borrowing cost. If Ellington can borrow cheaply and stay funded, it survives. If the repo market breaks, or if lenders get nervous and demand higher rates, the REIT is in trouble. The 2023 banking crisis reminded everyone that repo funding is not risk-free; multiple regional bank failures created jitters in short-term lending markets.

The third is rate expectations. If people believe rates will stay high for years, mortgage REITs will struggle, because the value of existing mortgages and securities will stay depressed. If people believe rates will fall, the opposite happens—the value of the held mortgages rises, and the REIT can benefit. Ellington’s stock price is thus a bet on interest rates as much as on the mortgage business itself.

What to watch

Every quarter, check the earnings report. Look at how much interest the company earned versus how much interest it paid on its borrowing. That spread is the business. Look at the size of the mortgage portfolio and whether it is growing or shrinking. A shrinking portfolio usually means the company is trying to reduce risk and lower leverage, often a sign that management thinks the environment is dangerous.

Check the “book value per share.” This is the net worth of the company divided by shares outstanding. If book value is falling, the company is losing money on a per-share basis even if distributions are continuing. That is a red flag.

Watch what the Federal Reserve does with interest rates. Rate cuts help mortgage REITs enormously; rate hikes hurt them. Track the mortgage market; if spreads are widening (the gap between what mortgages pay and what the company pays to borrow), Ellington’s margins are expanding. If spreads are shrinking, margin pressure is building.

Finally, pay attention to the company’s ability to access funding. If management starts talking about asset sales or capital raises, or if Wall Street starts charging higher rates to lend to the company, those are warning signs that trouble might be brewing. Mortgage REITs are creatures of capital markets; when those markets lose confidence, the game ends fast.
