Aggregate Leverage Limit (REIT) Singapore: The MAS Rule Capping S-REIT Borrowing

Last updated: August 2026

The aggregate leverage limit is the MAS-imposed ceiling on how much total debt a Singapore-listed REIT can carry relative to its total assets, currently set at 50% for all S-REITs, replacing an earlier two-tier system based on credit ratings.

Key Takeaways

MAS sets a single aggregate leverage limit of 50% of a REIT’s deposited property value for all Singapore-listed REITs, a rule simplified from a prior two-tier structure.
Before the rule was simplified in 2020, REITs with a credit rating and public disclosure of that rating could gear up to 45%, while unrated REITs were capped at 35%.
MAS separately requires REITs to maintain a minimum interest coverage ratio, generally 2.5 times, for gearing above 45%, adding a profitability-based check alongside the pure leverage cap.
Aggregate leverage is commonly referred to in the market simply as a REIT’s “gearing ratio,” and is calculated as total debt divided by total deposited property value.
A REIT operating close to the 50% ceiling has less headroom to raise further debt for acquisitions, often pushing it toward equity fundraising such as rights issues or private placements instead.

What Is Aggregate Leverage Limit (REIT) Singapore?

Singapore REITs are structured to distribute the bulk of their income to unitholders, which limits how much they can retain for growth, making borrowed capital an important funding source for acquisitions and asset enhancement. To manage the systemic and unitholder risk this creates, the Monetary Authority of Singapore sets a regulatory ceiling — the aggregate leverage limit — on how much debt a REIT can carry relative to the value of the properties it holds. This limit is a core plank of Singapore’s REIT regulatory framework, alongside disclosure, related-party transaction and distribution requirements, and directly shapes how much acquisition firepower a REIT has without needing to raise fresh equity.

How Does It Work in Singapore?

Aggregate leverage is calculated as a REIT’s total borrowings divided by its total deposited property value, expressed as a percentage. Historically, MAS allowed REITs with a public credit rating to gear up to 45%, while REITs without a credit rating faced a lower 35% cap, intended to reflect the additional scrutiny a credit rating provides. In October 2020, MAS simplified this to a single 50% leverage limit for all S-REITs regardless of credit rating, alongside introducing a minimum interest coverage ratio requirement of 2.5 times for any REIT gearing above 45%, ensuring that REITs taking on higher leverage can still comfortably service their interest obligations from operating income. A REIT approaching the 50% ceiling has correspondingly less room to add further debt, which often means it needs to fund additional acquisitions through equity fundraising, asset divestments, or by improving asset valuations rather than simply borrowing more.

Example

A REIT holds S$4 billion in total deposited property value and currently carries S$1.8 billion in total borrowings, giving it an aggregate leverage ratio of 45%. Under the current 50% ceiling, the REIT has roughly S$200 million of additional debt headroom before hitting the regulatory cap — though because its leverage already exceeds 45%, it must also maintain an interest coverage ratio of at least 2.5 times to stay compliant, meaning its operating income needs to cover its interest expense by that margin even as it considers further borrowing.

Advantages

Protects unitholders from excessive balance sheet risk by capping how much a REIT manager can leverage the trust’s assets, reducing the risk of forced asset sales or distribution cuts during a downturn.
The simplified single 50% limit, introduced in 2020, removed the complexity and disclosure burden of the prior credit-rating-dependent two-tier system.
The added interest coverage ratio requirement for higher-geared REITs provides a second, profitability-based safeguard on top of the pure asset-based leverage cap.
A known, consistent regulatory ceiling gives investors a clear benchmark to compare gearing discipline across different S-REITs.

Risks and Limitations

A REIT operating close to the 50% ceiling has limited flexibility to respond to opportunistic acquisitions or refinancing needs without turning to equity markets, which can dilute existing unitholders.
Rising interest rates increase debt servicing costs for REITs at any given leverage level, which is a separate risk from the leverage ratio itself but often moves together with it in practice.
The aggregate leverage limit measures asset-based leverage, not liquidity — a REIT can be within the leverage limit yet still face refinancing risk if a large tranche of debt matures during unfavourable market conditions.
Property valuations used in the deposited property value calculation can fluctuate, meaning a REIT’s leverage ratio can rise even without any new borrowing if asset values are revalued downward.

Aggregate Leverage Limit vs Interest Coverage Ratio

Feature	Aggregate Leverage Limit	Interest Coverage Ratio (ICR)
What it measures	Total debt as % of total deposited property value	Operating income relative to interest expense
Current MAS requirement	Maximum 50% for all S-REITs	Minimum 2.5x if gearing exceeds 45%
What it protects against	Balance sheet over-leverage relative to assets	Inability to service debt from operating income
Common market term	Gearing ratio	ICR or interest cover
Effect of rising interest rates	No direct effect on the ratio itself	Directly reduces ICR as interest expense rises
Effect of falling property valuations	Can raise the ratio even without new borrowing	No direct effect unless income is also affected

The Bottom Line

The aggregate leverage limit is the key regulatory guardrail on how much debt an S-REIT can carry, and together with the interest coverage ratio requirement, it shapes how much acquisition capacity a REIT has left before it must turn to equity markets to fund growth.

Frequently Asked Questions

What is the aggregate leverage limit for Singapore REITs?

It is the MAS-imposed ceiling on total borrowings relative to a REIT’s total deposited property value, currently set at 50% for all Singapore-listed REITs.

Has the aggregate leverage limit for S-REITs always been 50%?

No, before October 2020 MAS used a two-tier system allowing rated REITs up to 45% gearing and unrated REITs up to 35%, before simplifying to a single 50% limit for all REITs.

What happens if a REIT's leverage exceeds 45%?

MAS requires the REIT to maintain a minimum interest coverage ratio of 2.5 times, meaning its operating income must comfortably cover its interest expense at that higher leverage level.

Is aggregate leverage the same as gearing ratio?

Yes, aggregate leverage is commonly referred to as a REIT’s gearing ratio in market commentary, and both refer to the same total debt to total deposited property value calculation.

Why does a REIT's leverage ratio matter to investors?

A REIT closer to the 50% ceiling has less capacity to fund further acquisitions with debt, often signalling it may need to raise equity, which can dilute existing unitholders if it happens through a rights issue or placement.

Can a REIT's leverage ratio rise without it borrowing more money?

Yes, since the ratio is calculated against total deposited property value, a downward revaluation of the REIT’s properties can push the leverage ratio higher even without any additional borrowing.
