Mortgage REITs, or mREITs, are one of the most misunderstood corners of the REIT world — and one of the most important to understand clearly, because they're a distinctly higher-risk, more volatile category than the equity REITs most investors picture. Unlike an equity REIT, which owns buildings and earns rents, an mREIT doesn't own property at all. Instead, it owns mortgages and mortgage-backed securities (MBS), finances them with short-term borrowing, and earns the net interest margin — the spread between the yield on its assets and its cost of funding. To make that spread meaningful, mREITs use significant leverage, which amplifies both returns and risk. The result is a category that can offer high yields but with high volatility: dividends can be cut, book value can swing sharply, and the business is exposed to interest-rate moves, yield-curve shifts, and prepayment risk. This guide explains how mREITs make money, the net interest margin and leverage that drive them, why they're volatile, the rate and prepayment risks, and how to evaluate a mortgage REIT. This is a higher-risk category distinct from equity REITs; demand, returns, and outlook are discussed in general, non-promissory terms — past performance doesn't guarantee future results, and you should verify current conditions; this is educational information, not investment advice.
How mREITs Make Money
Mortgage REITs make money in a fundamentally different way from equity REITs, and grasping that difference is the key to understanding the category. An equity REIT owns physical real estate and earns rents from tenants. An mREIT owns no property; instead, it invests in real estate debt — mortgages and mortgage-backed securities (MBS) — and earns interest income from those assets. So where an equity REIT is a landlord collecting rent, an mREIT is more like a specialized lender or bond investor collecting interest on real estate loans and securities. This is the single most important and most commonly misunderstood fact about mREITs.
The way an mREIT generates profit is through the interest-rate spread. It borrows money at short-term rates and uses that borrowed money, plus its own capital, to buy higher-yielding mortgage assets. The profit comes from the difference between the interest the assets earn and the cost of the borrowing — the net interest margin. To make that spread produce a meaningful return on equity, mREITs borrow heavily, using significant leverage. So an mREIT's income is not rent but the spread between asset yields and funding costs, magnified by leverage. This spread-based, leveraged model is what gives mREITs their high yields and, as we'll see, their high volatility.
So an mREIT earns money from interest on mortgages and MBS — specifically the spread between asset yields and short-term funding costs, amplified by leverage — not from rents. So understanding this distinction frames everything else. How mREITs make money — by owning mortgages and mortgage-backed securities rather than property, financing them with short-term borrowing, and earning the net interest margin (the spread between asset yields and funding costs), magnified by significant leverage — sets them fundamentally apart from rent-earning equity REITs. They are spread-based lenders, not landlords. Understanding this distinction frames the entire category. mREITs earn the interest-rate spread on mortgages and MBS, not rents — financing assets with short-term borrowing and amplifying the spread with leverage.
Net Interest Margin & Leverage
The net interest margin (NIM) is the heart of an mREIT's business. It's the difference between the yield an mREIT earns on its mortgage assets and the cost of the funding it uses to buy them. For example, if an mREIT's assets yield more than the short-term rate at which it borrows, the gap is its margin — the raw spread it captures before expenses. The wider and more stable the margin, the more profitable the mREIT, all else equal. But the margin is not fixed: it changes as asset yields and funding costs move, which can compress or widen it over time, sometimes quickly.
Leverage is what turns a thin spread into a meaningful return — and a meaningful risk. Because the raw net interest margin on high-quality mortgage assets is often small, an mREIT borrows heavily, holding far more assets than its equity alone could buy, so that the spread is earned on a much larger base. This magnifies the return on equity when the spread is positive and stable. But leverage cuts both ways: it equally magnifies losses if the margin compresses or asset values fall, and it creates funding risk, since the mREIT must continually roll over its short-term borrowing. If funding costs spike or lenders demand more collateral, a highly leveraged mREIT can be forced to sell assets at bad prices. So leverage is the amplifier that makes mREITs both high-yielding and high-risk.
So the net interest margin is the spread an mREIT earns, and leverage magnifies that spread into both higher returns and higher risk. So together they define the mREIT engine. Net interest margin and leverage — the spread between asset yields and funding costs, multiplied by heavy borrowing so the spread is earned on a large asset base — are the core of how mREITs generate returns, amplifying gains when the spread is positive and stable but equally amplifying losses when it compresses or asset values fall, while adding funding risk. They make mREITs both high-yielding and high-risk. Understanding NIM and leverage explains the model. The net interest margin is the spread mREITs earn, and leverage magnifies it into higher returns and higher risk, plus funding risk.
- mREITs earn the interest-rate spread on mortgages and MBS — not rents — financing assets with short-term borrowing and amplifying the spread with significant leverage.
- Net interest margin (asset yields minus funding costs) is the core spread, and leverage magnifies both returns and losses, plus adds funding risk.
- mREITs are a higher-risk, more volatile category than equity REITs: dividends can be cut and book value can swing sharply.
- Key risks are interest-rate and yield-curve shifts and prepayment risk; agency mREITs face mainly rate and prepayment risk, while non-agency mREITs add credit risk.
Why mREITs Are Volatile
mREITs are notably more volatile than equity REITs, and the reasons trace directly to their leveraged, spread-based model. Because they use significant leverage, even modest moves in interest rates, spreads, or asset values are magnified at the equity level, so an mREIT's book value — the net value of its assets minus its borrowings — can swing sharply as conditions change. When rates and spreads move against the mREIT, leveraged losses can erode book value quickly; when they move in its favor, book value can recover. This sensitivity makes mREIT share prices and net asset values considerably more variable than those of rent-earning equity REITs.
The high dividends mREITs are known for are also less stable than they may appear. Because the payout depends on a leveraged net interest margin that can compress when rates and the yield curve shift, mREIT dividends can be — and historically have been — cut when conditions deteriorate. A high headline yield can therefore mask the risk that the distribution won't be sustained. Funding risk adds to the volatility: an mREIT relies on continually rolling over short-term borrowing, so a disruption in funding markets can force asset sales and deepen losses. For all these reasons, mREITs should be understood as a higher-risk, higher-volatility category — capable of attractive income but with real potential for sharp swings in both price and distributions. They are not a substitute for the steadier income of many equity REITs.
So mREITs are volatile because leverage magnifies rate, spread, and value moves into sharp swings in book value, share price, and dividends — making this a distinctly higher-risk category. So recognizing the volatility is essential. Why mREITs are volatile — leverage magnifying interest-rate, spread, and asset-value moves into sharp swings in book value, share price, and distributions, with dividends that can be cut and funding risk that can force asset sales — marks them as a higher-risk, higher-volatility category distinct from equity REITs. The high yield comes with real instability. Recognizing this volatility is essential before investing. mREITs are volatile because leverage magnifies rate and spread moves into sharp swings in book value and dividends, making them a higher-risk category than equity REITs.
An mREIT's high yield is not a free lunch: leverage that magnifies the spread in good times magnifies the damage in bad ones, which is why both book value and the dividend can fall hard and fast.
Rate & Prepayment Risk
Interest-rate risk is the central risk for mREITs, because their entire business is built on the spread between asset yields and funding costs. When short-term rates rise, an mREIT's funding costs increase, which can compress the net interest margin if asset yields don't keep pace. Yield-curve shifts matter too: mREITs typically borrow short and lend long, so a flattening or inverted yield curve — where short-term rates approach or exceed long-term rates — can squeeze or even eliminate the spread. Because leverage magnifies these effects, even moderate rate and curve movements can have an outsized impact on an mREIT's earnings and book value, which is why rate risk dominates the category.
Prepayment risk is the other defining risk, and it's somewhat counterintuitive. When interest rates fall, homeowners tend to refinance their mortgages, paying off their existing loans early. For an mREIT holding those mortgages or MBS, that early repayment returns principal that must be reinvested at the new, lower rates — compressing the spread just when falling rates might otherwise seem helpful. So mREITs can be squeezed when rates rise (higher funding costs) and when they fall (prepayments and reinvestment at lower yields). A further distinction matters here: agency mREITs hold government-backed MBS and face mainly interest-rate and prepayment risk, while non-agency mREITs hold non-guaranteed mortgage assets and take on added credit risk — the risk that borrowers default. Hedging can mitigate some rate and prepayment exposure, but it adds cost and complexity and is never perfect.
So rate and prepayment risk define mREITs: rising rates and curve shifts can compress the spread, falling rates trigger prepayments, and agency versus non-agency determines whether credit risk is added. So these risks are central to the category. Rate and prepayment risk — rising short-term rates and yield-curve flattening compressing the spread, falling rates triggering prepayments that force reinvestment at lower yields, all magnified by leverage, with agency mREITs facing mainly rate and prepayment risk and non-agency mREITs adding credit risk — are the defining risks of mortgage REITs. Hedging can mitigate but not eliminate them. Understanding these risks is essential. Rate and prepayment risk define mREITs: rising rates and curve shifts squeeze the spread, falling rates cause prepayments, and non-agency mREITs add credit risk on top.
Agency vs. Non-Agency mREITs
Within the mortgage REIT category, the most important distinction is between agency and non-agency mREITs, because it determines what kinds of risk an mREIT takes on. Agency mREITs invest in mortgage-backed securities that are guaranteed by government-related agencies, so the credit risk — the risk that the underlying borrowers default — is effectively backstopped by the guarantee. As a result, agency mREITs are exposed mainly to interest-rate risk and prepayment risk: their earnings and book value move with rates, the yield curve, and refinancing activity, but they're largely shielded from credit losses. This makes agency mREITs a relatively 'cleaner' rate-and-prepayment play, though leverage still makes them volatile.
Non-agency mREITs invest in mortgage assets that are not government-guaranteed — such as private-label MBS or other non-agency loans — so they take on added credit risk on top of the rate and prepayment risks. If borrowers default, a non-agency mREIT can suffer losses that an agency mREIT would be insulated from, particularly in a weakening economy or housing market. To compensate for that extra credit exposure, non-agency assets typically offer higher yields, but the higher yield comes with higher risk. Many mREITs hold a mix of agency and non-agency assets, so understanding the blend — and how much credit risk the mREIT is taking — is essential. So the agency-versus-non-agency distinction is a key dimension of an mREIT's risk profile, layered on top of leverage and rate sensitivity.
So agency mREITs face mainly rate and prepayment risk while non-agency mREITs add credit risk for higher yield — a distinction central to an mREIT's risk profile. So understanding the mix is essential before investing. Agency versus non-agency mREITs — agency mREITs holding government-guaranteed MBS and facing mainly interest-rate and prepayment risk, versus non-agency mREITs holding non-guaranteed assets that add credit risk in exchange for higher yields — is a defining dimension of mREIT risk, layered on top of leverage and rate sensitivity, and many mREITs hold a blend. The mix determines how much credit risk you're taking. Understanding agency versus non-agency is essential. Agency mREITs face mainly rate and prepayment risk; non-agency mREITs add credit risk for higher yield — so knowing the mix is essential.
The agency-versus-non-agency line is where an mREIT's risk really lives: agency assets carry a government backstop on credit, while non-agency assets pay more precisely because they don't.
Evaluating Mortgage REITs
Evaluating an mREIT requires a different lens than an equity REIT, since there are no rents or properties to assess — the analysis centers on the balance sheet and the spread. Start with leverage: how much is the mREIT borrowing relative to its equity? Higher leverage means higher potential returns but far greater risk and fragility, so leverage is the first thing to size up. Then look at book-value trends: because an mREIT's value is the net of its assets and borrowings, the trajectory of book value over time tells you whether the mREIT has been preserving or eroding shareholder capital through rate and spread cycles. A persistent decline in book value is a serious warning sign that high dividends may be masking capital erosion.
Next, examine the net interest margin and the spread — how wide and stable is it, and how exposed is it to rate and curve shifts? Assess hedging: does management hedge its interest-rate and prepayment exposure, at what cost, and how effectively? Evaluate management quality and track record, since navigating leverage, rates, and prepayments well is difficult and varies greatly by team. Determine whether the mREIT is agency (mainly rate and prepayment risk) or non-agency (added credit risk), since that shapes the risk profile. Finally, read the high dividend with skepticism — it can be cut, and book value can swing — and treat this as a higher-risk category distinct from equity REITs. Past performance doesn't guarantee future results; verify current conditions, leverage, and book-value trends rather than relying on a headline yield.
So evaluating an mREIT means weighing leverage, book-value trends, the spread and net interest margin, hedging, management quality, and agency versus non-agency status. So a disciplined, risk-focused framework is essential. Evaluating mortgage REITs centers on leverage, book-value trends, the net interest margin and spread, hedging effectiveness and cost, management quality, and whether the mREIT is agency or non-agency — with the high dividend read skeptically as it can be cut and book value can swing. This is a higher-risk category requiring a balance-sheet-focused analysis. Understanding this framework guides a disciplined evaluation. Evaluate an mREIT by leverage, book-value trends, the spread, hedging, management quality, and agency versus non-agency status — reading the yield with skepticism.

Frequently Asked Questions
What is a mortgage REIT (mREIT)?
A mortgage REIT, or mREIT, is a Real Estate Investment Trust that finances real estate rather than owning it. Unlike an equity REIT, which owns physical property and earns rents from tenants, an mREIT owns no buildings; instead, it invests in real estate debt — mortgages and mortgage-backed securities (MBS) — and earns interest income from those assets. It finances them largely with short-term borrowing and profits from the net interest margin, the spread between the yield on its mortgage assets and its cost of funding, amplified by significant leverage. So an mREIT is more like a specialized lender or leveraged bond investor than a landlord. This makes mREITs a distinctly different and higher-risk category than equity REITs: they offer high yields but with high volatility, their dividends can be cut, and their book value can swing sharply with interest rates and prepayments. So a mortgage REIT earns the interest-rate spread on mortgages and MBS using leverage, not rents on property — a commonly misunderstood distinction that defines the whole category.
How do mortgage REITs make money?
Mortgage REITs make money from the interest-rate spread, not from rents. An mREIT borrows money at short-term rates and uses that borrowed money, together with its own equity, to buy higher-yielding mortgage assets — mortgages and mortgage-backed securities (MBS). Its profit comes from the difference between the interest those assets earn and the cost of the borrowing, which is called the net interest margin. Because the raw margin on high-quality mortgage assets is often thin, mREITs use significant leverage — borrowing heavily so the spread is earned on a much larger asset base — to turn that thin spread into a meaningful return on equity. So an mREIT's income is the leveraged net interest margin: asset yields minus funding costs, magnified by borrowing. This is fundamentally different from an equity REIT, which owns buildings and collects rent. It also means an mREIT's earnings rise and fall with interest rates, the yield curve, and funding costs, which is why the category is higher-risk and more volatile.
What is the net interest margin?
The net interest margin (NIM) is the core measure of an mREIT's profitability: the difference between the yield it earns on its mortgage assets and the cost of the funding it uses to buy them. If an mREIT's mortgage and MBS holdings yield more than the short-term rate at which it borrows, the gap is its margin — the raw spread it captures before expenses. The wider and more stable that margin, the more profitable the mREIT, all else equal. But the net interest margin isn't fixed: it changes as asset yields and funding costs move, so it can compress or widen over time, sometimes quickly. Rising short-term rates can increase funding costs and squeeze the margin; a flattening or inverted yield curve can squeeze it further; and prepayments when rates fall can force reinvestment at lower yields, also compressing it. Because mREITs use leverage, even small changes in the net interest margin have a magnified effect on returns. So the net interest margin is the spread at the heart of an mREIT, and its stability is central to the mREIT's earnings and dividend.
Why do mortgage REITs use leverage?
Mortgage REITs use leverage because the raw net interest margin on high-quality mortgage assets is often small, and leverage is what turns that thin spread into a meaningful return on equity. By borrowing heavily, an mREIT holds far more assets than its equity alone could buy, so the spread is earned on a much larger base — magnifying the return when the spread is positive and stable. That's the appeal. But leverage is a double-edged sword: it equally magnifies losses when the margin compresses or asset values fall, and it creates funding risk, because the mREIT must continually roll over its short-term borrowing. If funding costs spike or lenders demand more collateral, a highly leveraged mREIT can be forced to sell assets at unfavorable prices, deepening losses. So leverage is the amplifier that makes mREITs both high-yielding and high-risk, and it's the first thing to assess when evaluating one. The more leverage an mREIT uses, the greater both its potential return and its fragility — which is why leverage is central to the category's volatility.
Why are mortgage REITs more volatile than equity REITs?
Mortgage REITs are more volatile than equity REITs because of their leveraged, spread-based model. Since they use significant leverage, even modest moves in interest rates, spreads, or asset values are magnified at the equity level, so an mREIT's book value — the net of its assets minus its borrowings — can swing sharply as conditions change. Equity REITs, by contrast, own buildings and earn relatively stable rents, so their values tend to move less abruptly. mREIT dividends are also less stable: the payout depends on a leveraged net interest margin that can compress when rates and the yield curve shift, so dividends can be — and historically have been — cut when conditions deteriorate. Funding risk adds further volatility, since an mREIT relies on continually rolling over short-term borrowing, and a disruption can force asset sales. So mREITs combine high yields with real potential for sharp swings in price, book value, and distributions, making them a distinctly higher-risk, higher-volatility category that shouldn't be treated as a substitute for the steadier income of many equity REITs.
What is prepayment risk in mortgage REITs?
Prepayment risk is one of the defining risks of mortgage REITs, and it's somewhat counterintuitive. When interest rates fall, homeowners tend to refinance their mortgages, paying off their existing loans early. For an mREIT that holds those mortgages or mortgage-backed securities, the early repayment returns principal sooner than expected — principal that must then be reinvested at the new, lower prevailing rates. This compresses the mREIT's spread precisely when falling rates might otherwise seem favorable. So prepayments mean an mREIT can be squeezed when rates fall, just as it can be squeezed when rates rise (through higher funding costs). Prepayment risk is most associated with agency mortgage assets, where the main exposures are interest-rate and prepayment risk rather than credit risk. mREITs may use hedging to manage some of this exposure, but hedging adds cost and complexity and is never perfect. So prepayment risk is the risk that falling rates trigger early loan repayments, forcing reinvestment at lower yields and compressing the spread — a key reason mREITs are sensitive to rate moves in both directions.
What is the difference between agency and non-agency mREITs?
The difference between agency and non-agency mREITs comes down to credit risk. Agency mREITs hold mortgage-backed securities that are guaranteed by government-related agencies, so the credit risk — the risk that borrowers default — is effectively backstopped. As a result, agency mREITs face mainly interest-rate risk and prepayment risk: their earnings and book value move with rates, the yield curve, and refinancing activity, but they're largely shielded from credit losses. Non-agency mREITs, by contrast, hold mortgage assets that are not government-guaranteed, so they take on added credit risk on top of rate and prepayment risk — if borrowers default, the mREIT can suffer losses. Non-agency assets typically offer higher yields to compensate for that added credit exposure, but they're riskier, especially in a weakening economy or housing market. So the agency-versus-non-agency distinction determines whether an mREIT is exposed mainly to rates and prepayments (agency) or also to credit risk (non-agency). When evaluating an mREIT, knowing which type it is — and its mix — is essential to understanding its risk profile.
Are mortgage REITs risky?
Yes — mortgage REITs are a distinctly higher-risk category, and that should be understood clearly before investing. Their risk comes from several sources working together. They use significant leverage, which magnifies both returns and losses and creates funding risk from rolling over short-term borrowing. They're highly exposed to interest-rate risk and yield-curve shifts, since their entire business is the spread between asset yields and funding costs. They face prepayment risk, where falling rates trigger refinancing that compresses the spread. Non-agency mREITs add credit risk on top. As a result, mREIT book value can swing sharply, share prices are volatile, and dividends can be cut when conditions deteriorate — a high headline yield can mask real instability. So while mREITs can offer attractive income, they are not low-risk or bond-like; they're a leveraged, rate-sensitive, volatile category that requires careful analysis and appropriate sizing. They're best understood as a higher-risk, specialized holding rather than a core income substitute. Past performance doesn't guarantee future results; verify current conditions.
How do interest rates affect mortgage REITs?
Interest rates are the central driver of mortgage REITs, because their entire business is built on the spread between asset yields and funding costs. When short-term rates rise, an mREIT's funding costs increase, which can compress the net interest margin if asset yields don't keep pace, squeezing earnings. Yield-curve shifts matter too: mREITs typically borrow short and lend long, so a flattening or inverted yield curve — where short-term rates approach or exceed long-term rates — can shrink or even eliminate the spread. When rates fall, the problem flips: homeowners refinance, prepaying their mortgages and forcing the mREIT to reinvest principal at lower yields, which also compresses the spread. Because mREITs use significant leverage, even moderate rate and curve movements have an outsized impact on earnings and book value. So mREITs can be squeezed when rates rise and when they fall, and their book values and dividends are highly sensitive to the rate environment. This pervasive rate sensitivity is why mREITs are among the most interest-rate-driven investments in the REIT universe, and why rate risk dominates their evaluation.
Can mortgage REIT dividends be cut?
Yes — mortgage REIT dividends can be, and historically have been, cut, even though mREITs are known for high yields. The dividend depends on a leveraged net interest margin that can compress when interest rates rise, the yield curve flattens, or prepayments force reinvestment at lower yields. When the spread narrows, the mREIT earns less, and the high payout can become unsustainable, leading to a dividend cut. Leverage magnifies these pressures, and funding-market disruptions can force asset sales that further hurt earnings and book value. So a high headline yield on an mREIT should be read with caution — it can mask the risk that the distribution won't be sustained, and an unusually high yield sometimes signals that the market expects a cut. Unlike the steadier income of many equity REITs backed by rents, an mREIT's dividend rides on a volatile, leveraged spread. So mREIT dividends are not guaranteed and can change meaningfully as rates and spreads move. When evaluating an mREIT, look at book-value trends and spread stability, not just the current yield, to judge dividend durability.
What is book value and why does it matter for mREITs?
Book value, for an mREIT, is the net value of its assets minus its borrowings — essentially the shareholders' equity, often expressed per share. It matters enormously because an mREIT's value rests on this net figure rather than on physical buildings. Since mREITs use significant leverage, even modest moves in interest rates, spreads, or the value of their mortgage assets are magnified at the equity level, so book value can swing sharply as conditions change. The trajectory of book value over time is one of the most important indicators when evaluating an mREIT: a stable or growing book value suggests management is preserving shareholder capital through rate and spread cycles, while a persistent decline is a serious warning sign that high dividends may actually be masking erosion of capital. In other words, a generous yield means little if the underlying book value is steadily shrinking. So when analyzing an mREIT, look beyond the dividend to the book-value trend, because it reveals whether the mREIT is genuinely creating value or simply returning — and depleting — capital while rates and spreads move against it.
How do I evaluate a mortgage REIT?
Evaluating an mREIT requires a balance-sheet-focused lens, since there are no rents or buildings to assess. Start with leverage: how much is the mREIT borrowing relative to its equity? Higher leverage means greater potential return but far more risk and fragility. Then study book-value trends, because the trajectory of book value over time shows whether the mREIT has been preserving or eroding shareholder capital through rate and spread cycles — a persistent decline is a red flag. Examine the net interest margin and spread: how wide and stable is it, and how exposed is it to rate and yield-curve shifts? Assess hedging — whether and how effectively management hedges rate and prepayment exposure, and at what cost. Evaluate management quality and track record, since navigating leverage, rates, and prepayments well is difficult and varies by team. Determine whether the mREIT is agency (mainly rate and prepayment risk) or non-agency (added credit risk). Finally, read the high dividend skeptically, since it can be cut. So evaluate an mREIT by leverage, book value, spread, hedging, management, and agency status — not by yield alone.
How are mortgage REITs different from equity REITs?
Mortgage REITs and equity REITs are fundamentally different, and confusing them is a common mistake. An equity REIT owns physical real estate — apartments, warehouses, offices, retail — and earns income mainly from the rents its tenants pay, with property appreciation as an additional source over time; its value rests on buildings and leases, and metrics like FFO, AFFO, and NAV apply. A mortgage REIT owns no property; it finances real estate by holding mortgages and mortgage-backed securities, earning the interest-rate spread between asset yields and funding costs, amplified by leverage. Its value rests on a leveraged balance sheet, and it's analyzed through leverage, book value, and net interest margin rather than rents. As a result, mREITs are far more interest-rate-sensitive and volatile than most equity REITs, their dividends are less stable, and their book values can swing sharply. So an equity REIT is a landlord earning rents, while an mREIT is a leveraged lender earning a spread — a higher-risk, more volatile category that should be understood as distinct from the equity REITs most investors picture when they think of real estate.
What is yield-curve risk for mortgage REITs?
Yield-curve risk is one of the most important risks for mortgage REITs, because of how they make money. mREITs typically borrow at short-term rates and invest in longer-term mortgage assets, so they profit from the gap between long-term asset yields and short-term funding costs — a positive, upward-sloping yield curve is favorable for them. Yield-curve risk is the danger that the shape of the curve changes against the mREIT. When the curve flattens — short-term rates rising toward long-term rates — the spread between what the mREIT earns and what it pays narrows, compressing the net interest margin. When the curve inverts, with short-term rates above long-term rates, the spread can shrink dramatically or even turn negative, which is especially damaging for a leveraged borrow-short-lend-long business. Because mREITs use significant leverage, these curve shifts are magnified at the equity level, hitting earnings and book value hard. So yield-curve risk means an mREIT's profitability depends not just on the level of interest rates but on the relationship between short- and long-term rates, and an adverse change in the curve's shape can squeeze the spread that the whole business relies on.
