How Interest Rates Affect Mortgage REITs
This tool shows how changing interest rates impact mortgage REITs' spreads, book value, and dividend sustainability. Based on article analysis of spread risk and volatility.
Projected Impact
When you see a mortgage REIT offering a 10% dividend yield, it’s easy to think you’ve found a goldmine. But behind that high payout is a complex, high-stakes game driven by interest rates, leverage, and the ever-shifting value of mortgage-backed securities. Unlike equity REITs that own apartment buildings or shopping centers, mortgage REITs make money by lending money - specifically, by buying mortgages and mortgage-backed securities (MBS) and earning the spread between what they earn on those loans and what they pay to borrow money. That spread is everything. And when it narrows, your dividends can vanish.
How Mortgage REITs Actually Make Money
Mortgage REITs don’t buy houses. They buy loans. Think of them as middlemen between the Fed and homeowners. They borrow money at short-term rates - often using overnight repurchase agreements (repos) - and use that cash to buy long-term mortgages or MBS that pay higher interest. The difference between the two rates? That’s their profit. If they borrow at 4% and earn 6% on their MBS, they make a 2% spread. Simple, right? But here’s the catch: they borrow 8 or 9 times more than their own capital. That’s leverage. And leverage turns small spreads into big returns - or big losses.
Because they’re legally required to pay out 90% of their taxable income as dividends, mREITs have no choice but to distribute nearly all their earnings. That’s why yields are so high - often double or triple what you’d get from a 10-year Treasury. But that same rule means they can’t hold onto profits to weather storms. When spreads shrink, they don’t have a cushion. They cut dividends.
Book Value Volatility: The Hidden Roller Coaster
Every quarter, mortgage REITs must mark their mortgage portfolios to market. That means if interest rates rise, the value of their existing MBS drops - because new bonds pay more, so old ones become less valuable. A 1% increase in rates can wipe out 2% to 5% of their book value, depending on how long the underlying mortgages are. This isn’t theoretical. In Q1 2020, AGNC Investment Corp’s book value fell 31.5% in just three months. That’s not a paper loss - it’s real capital erosion.
And here’s the kicker: stock prices often fall even harder than book value. Why? Because investors panic. If a REIT’s book value drops 15%, its stock might drop 30% because people fear the dividend will be cut next. That’s what happened to Annaly Capital Management in early 2024 - book value fell 19.6% in six months, and while the dividend stayed the same, the stock price tanked. Investors weren’t just reacting to the numbers - they were reacting to fear.
Spread Risk: The Silent Killer of Dividends
The biggest threat to mREIT dividends isn’t inflation. It’s not even a recession. It’s a flattening yield curve. When the Fed raises short-term rates faster than long-term rates, the spread between borrowing costs and mortgage yields collapses. In 2018-2019, the 2-year/10-year Treasury yield curve inverted. Result? mREIT dividends fell 18.3% on average. Meanwhile, equity REITs - which earn rent - saw their dividends rise 2.1%.
Today, the spread between 10-year Treasuries and mortgage rates sits at around 170 basis points - near its lowest level since 2000. Historically, it’s been 225. That’s a 55-basis-point cushion gone. If rates rise another 25-50 basis points, many mREITs will be barely breaking even after funding costs. And if funding markets freeze - like they did in March 2020 - borrowing costs can spike to 10% overnight. That’s not a risk. That’s a guarantee of dividend cuts.
Why mREITs Are Different from Equity REITs
Equity REITs own buildings. Their income comes from leases. Even if interest rates rise, rent increases can offset higher borrowing costs. They’re slow-moving, stable, and predictable. mREITs? They’re like hedge funds dressed as real estate companies. Their income depends entirely on the spread between two rates they can’t control. And their assets - MBS - are marked to market every day. That’s why in 2022, when the Fed hiked rates, mREITs lost 23.7% in book value. Equity REITs? Only 14.2%. The dividend yield gap was huge - 10.2% for mREITs versus 3.8% for equity REITs - but the risk wasn’t just higher. It was structurally different.
Equity REITs can raise rents. mREITs can’t raise mortgage rates. They’re stuck with the loans they bought. If those loans get paid off early - because homeowners refinance - their income drops. That’s called prepayment risk. A 10% jump in refinancing can slash net interest margins by 15 basis points. And there’s nothing they can do about it.
What Smart Investors Watch For
If you’re holding mREITs, you’re not just holding a dividend. You’re holding a bet on interest rates, funding markets, and hedge effectiveness. Here’s what to track:
- Book value per share: Is the stock trading at a 20% discount to book? That’s often a sign of overselling. If it’s trading at a 10% premium? Watch out - the dividend might be at risk.
- Dividend coverage: Look at core earnings, not GAAP earnings. Core earnings strip out one-time gains or losses. If core earnings cover the dividend by less than 100%, the payout is vulnerable.
- The TED spread: This measures the gap between 3-month LIBOR and 3-month Treasury yields. When it climbs above 50 basis points, mREITs have cut dividends 82% of the time within six months.
- Hedge ratios: Do they use interest rate swaps to lock in spreads? As of 2024, top mREITs hedge 65% of their duration risk - up from 35% in 2018. That’s good. But swaps aren’t perfect. They cost money. And they expire.
- Funding concentration: If a REIT relies too heavily on repo markets - which 62% of them do - a single shock can freeze their ability to borrow.
Real Investor Stories
One investor on Reddit held AGNC since 2019. The dividend fell from $0.45 per quarter to $0.15 in 2022 - a 67% cut. He didn’t sell. He waited. By 2024, the dividend had recovered to $0.30. His total return? Still positive, thanks to the high yield during the cut and the eventual rebound.
Another investor held Chimera Investment Corp (CIM) since 2020. Book value dropped 12.3%. But the 8.5% average yield over that time gave him a 22.1% total return. He didn’t chase yield - he understood the risk. He held through the volatility.
But then there’s the 68% of negative reviews on StockAnalysis.com that say: “The dividend cuts are unpredictable.” That’s the real problem. You can’t rely on mREIT dividends the way you can on Coca-Cola or Johnson & Johnson. They’re cyclical. They’re volatile. And they’re not for passive investors.
Should You Invest in mREITs?
If you’re looking for stable, growing income - stick with equity REITs or dividend aristocrats. If you’re comfortable with volatility, understand interest rate mechanics, and have the patience to ride out dividend cuts, mREITs can deliver outsized returns. The key is knowing when to buy and when to walk away.
Look for mREITs trading at a 15-25% discount to book value. Check their hedge ratios. Watch the TED spread. Monitor core earnings. And never assume the dividend is safe just because it’s been paid for 10 quarters.
The sector has shrunk from 32 mREITs in 2021 to 24 today. The survivors are smarter. They hedge more. They borrow less. But the core risk hasn’t changed. Interest rates move. Spreads shrink. Book values fall. Dividends cut. That’s the cycle. And it always repeats.
As of mid-2024, the Federal Reserve’s Financial Stability Report still labels mREITs as “elevated vulnerability to interest rate shocks.” That’s not a warning you can ignore. It’s a fact of life in this market.
What’s Next for Mortgage REITs?
The sector’s future depends on two things: interest rate stability and investor tolerance for volatility. If the 10-year Treasury stabilizes between 4.0% and 4.5%, mREIT assets could grow to $158 billion by 2026. But if the Fed hikes again, or if funding markets tighten, expect another wave of book value declines and dividend cuts.
New tools are emerging - like the first actively managed mREIT ETF, Global X MREI, launched in June 2024. It tries to shift between residential and commercial mREITs based on value signals. That’s smart. But it doesn’t eliminate risk. It just tries to manage it.
For now, mREITs remain a high-risk, high-reward play. They’re not for everyone. But for those who understand the mechanics, they offer one of the few remaining sources of double-digit yields in a low-rate world. Just don’t forget: the higher the yield, the more you’re paying for risk.
Why do mortgage REITs pay such high dividends?
Mortgage REITs are required by law to distribute at least 90% of their taxable income as dividends to avoid corporate taxes. Since their profits come from narrow interest rate spreads, they must pay out nearly all earnings to remain profitable. This forces them to offer high yields - often 8-12% - to attract investors despite the high risk.
Can mortgage REITs cut their dividends?
Yes, and they do - often. Dividend cuts happen when interest rate spreads shrink, funding costs rise, or mortgage prepayments increase. In 2022, the average mREIT dividend was cut by 23.4%. Some, like AGNC, cut dividends by over 60%. Unlike equity REITs, mREITs can’t raise rents to offset losses - their income is tied directly to interest rate movements.
What is book value volatility, and why does it matter?
Book value is the net asset value of a mortgage REIT’s portfolio, calculated by subtracting debt from the market value of its mortgage holdings. Because these assets are marked to market daily, rising interest rates cause their value to drop - sometimes sharply. A 1% rise in rates can reduce book value by 2-5%. This volatility scares investors, causing stock prices to fall even more than book value, which can trigger dividend cuts or forced asset sales.
How do interest rate hikes affect mortgage REITs?
Interest rate hikes hurt mREITs in two ways: First, they raise borrowing costs immediately, squeezing the spread between what they earn and what they pay. Second, they reduce the market value of existing mortgage-backed securities, lowering book value. While equity REITs can pass higher costs to tenants, mREITs can’t adjust mortgage rates on loans they already own. This makes them uniquely sensitive to Fed policy.
Are mortgage REITs a good hedge against inflation?
Not directly. While rising inflation often leads to higher interest rates, which can boost mREIT yields, the lag in mortgage rate adjustments and the compression of spreads usually hurt them more than help. Historically, mREITs have performed poorly during rapid rate hikes, even when inflation is high. Their correlation with 10-year Treasury yields is 0.87 - meaning they move closely with rates, not inflation.
What’s the difference between core earnings and GAAP earnings in mREITs?
GAAP earnings include one-time gains or losses from selling assets, changes in fair value, and other non-recurring items. Core earnings strip those out and show only the recurring income from interest spreads - the true measure of a mortgage REIT’s ability to pay dividends. Investors should always compare dividends to core earnings, not GAAP earnings, to assess sustainability.
Should I invest in individual mREITs or an ETF?
For most investors, an ETF like VanEck MORT or Global X MREI is safer. Individual mREITs carry heavy company-specific risk - one bad hedge, one funding shock, or one misjudged prepayment rate can destroy value. ETFs spread that risk across 15-20 companies. Plus, ETFs offer lower minimums and better liquidity. Only experienced investors who track quarterly reports and hedge ratios should consider single stocks.

10% yield?? Bro, that’s not income-that’s a dare 😅 I held AGNC in 2022 and watched my dividend get slashed like a horror movie. But hey, I still got my 8% average yield over 5 years. Risk? Yeah. Reward? Also yeah. 🤑📈
