Interest Coverage Ratio (REIT): Can Your S-REIT Actually Afford Its Debt?
Interest coverage ratio (ICR) measures how many times over a REIT’s earnings before interest and tax (EBIT) can cover its interest expense, calculated as EBIT divided by interest expense, and is a key indicator of how comfortably a REIT can service its debt obligations.

Key Takeaways
- ICR = EBIT (or a similar earnings measure) ÷ Interest Expense, with a higher number indicating a larger buffer before interest payments become a strain on the REIT’s finances.
- MAS requires S-REITs to maintain a minimum ICR of 2.5 times if they wish to gear up (borrow) beyond 45% of total assets, up to the overall 50% aggregate leverage cap.
- Rising interest rates directly reduce ICR by increasing interest expense, even if a REIT’s underlying rental income (and therefore EBIT) stays unchanged — making ICR especially sensitive during rate-hiking cycles.
- A REIT with a large proportion of fixed-rate debt or interest rate hedges is generally more protected from ICR deterioration during a rising rate environment than one with mostly floating-rate debt.
- ICR works alongside gearing ratio: a REIT can have moderate gearing but a weak ICR if its cost of debt is unusually high, or vice versa — both metrics are needed for a complete risk picture.
What Is Interest Coverage Ratio (REIT)?
While gearing ratio tells an investor how much debt a REIT is carrying relative to its assets, interest coverage ratio answers a related but distinct question: given the REIT’s current earnings, how easily can it actually afford to pay the interest on that debt? A REIT could have moderate, seemingly safe gearing, but if its average cost of borrowing is unusually high (perhaps because its debt was taken on during a period of elevated interest rates), its interest coverage ratio could still be uncomfortably thin.
ICR is calculated as EBIT (earnings before interest and tax) divided by total interest expense for the period. A REIT with an ICR of 4.0 times means its earnings are four times larger than what it needs to pay in interest — a comfortable buffer. A REIT with an ICR of 1.5 times has much less room; even a moderate drop in rental income or a rise in interest rates could push it close to breaching loan covenants or straining its ability to maintain distributions.
ICR became a particularly important metric for Singapore REIT investors during the 2022–2023 global rate-hiking cycle, when many S-REITs saw their average cost of debt rise meaningfully as fixed-rate loans matured and had to be refinanced at much higher prevailing rates, compressing ICR across the sector even where underlying rental income remained healthy or grew.
How Does It Work in Singapore?
MAS directly ties ICR to a REIT’s ability to take on additional leverage: under the current framework, an S-REIT can only gear up beyond 45% of total assets (up to the 50% ceiling) if it maintains a minimum ICR of 2.5 times, based on a look-forward basis that accounts for interest expense on new committed capital. This rule was specifically designed to prevent REITs from maximising leverage without also maintaining an adequate buffer to service that debt comfortably.
REIT managers in Singapore typically report ICR each quarter alongside gearing ratio, and many also disclose the proportion of their total debt that is hedged or fixed-rate versus floating-rate, since this detail helps investors judge how exposed the REIT’s ICR is to further interest rate movements. A REIT with, say, 80% of its debt on fixed rates is considerably more insulated from near-term ICR deterioration than one with the reverse mix.
| ICR Level | General Interpretation |
|---|---|
| Above 4.0x | Strong buffer; low near-term servicing risk |
| 2.5x–4.0x | Adequate; meets MAS’s minimum requirement to gear beyond 45% |
| Below 2.5x | Weak; restricts further gearing beyond 45% under MAS rules |

Interest Coverage Ratio (REIT) Example
Suppose a hypothetical S-REIT, “DEF REIT”, reports EBIT of SGD 120 million for the financial year and total interest expense of SGD 30 million.
ICR = SGD 120,000,000 ÷ SGD 30,000,000 = 4.0 times.
This comfortably exceeds MAS’s 2.5x minimum requirement for REITs wishing to gear beyond 45%, giving DEF REIT flexibility to take on additional leverage for future acquisitions if it chooses to.
Now suppose interest rates rise and DEF REIT needs to refinance SGD 500 million of maturing fixed-rate debt (previously at 2.5% per annum) at a new rate of 4.5% per annum. This alone adds SGD 10 million in annual interest expense (SGD 500 million × 2.0 percentage point increase), bringing total interest expense to SGD 40 million. If EBIT stays flat, the new ICR = SGD 120,000,000 ÷ SGD 40,000,000 = 3.0 times — still above the 2.5x minimum, but a meaningfully thinner buffer than before, illustrating how refinancing at higher rates can erode ICR even without any change in underlying property performance.
Advantages
Directly measures debt-servicing comfort. Unlike gearing ratio, which only looks at the debt-to-asset relationship, ICR shows whether current earnings can actually support the interest payments on that debt.
Tied to a clear regulatory threshold. MAS’s 2.5x minimum ICR requirement for REITs gearing beyond 45% gives investors a clear, enforced benchmark to assess whether a REIT has room to take on more leverage.
Highlights refinancing risk early. Tracking ICR trends over time can reveal early warning signs if a REIT’s cost of debt is rising faster than its earnings, before the situation becomes a more serious financial strain.
Complements gearing ratio for a fuller risk picture. Combining ICR with gearing ratio gives a more complete view of a REIT’s financial risk than either metric could provide on its own.
Risks and Limitations
Highly sensitive to interest rate cycles. ICR can deteriorate meaningfully during a rate-hiking cycle, even without any change in a REIT’s underlying rental income, simply because the cost of refinancing maturing debt rises.
EBIT can be affected by one-off items. Because ICR uses EBIT as its numerator, one-off gains or losses (such as from a property divestment) can temporarily distort the ratio, making it important to look at adjusted or recurring EBIT where disclosed.
Doesn’t capture the full debt maturity profile. A REIT might show a healthy current ICR, but if a large proportion of its debt matures within the next year and needs refinancing at much higher rates, future ICR could deteriorate sharply.
Varies significantly by reporting methodology. Different REIT managers may calculate EBIT or adjusted earnings slightly differently for ICR purposes, making like-for-like comparisons across REITs less straightforward than they first appear.
A high ICR doesn’t guarantee a safe DPU. Even with a comfortable ICR, a REIT’s distribution could still be pressured by other factors such as high capital expenditure needs, declining occupancy, or large upcoming lease expiries.
The Bottom Line
For Singapore REIT investors, interest coverage ratio reveals whether a REIT can comfortably afford the debt shown on its balance sheet — a metric that matters even more during periods of rising interest rates, and one that should always be read together with gearing ratio and debt maturity profile.
