In the context of Singapore REITs, Assets Under Management (AUM) refers to the total gross value of all properties and real estate assets managed by the REIT manager on behalf of unitholders. AUM measures a REIT’s scale, diversification potential, and growth trajectory. Understanding AUM helps Singapore investors compare S-REITs across sectors and assess long-term income sustainability. This is for educational purposes only and does not constitute financial advice.
How AUM Is Calculated for S-REITs
For S-REITs, AUM equals the total Gross Asset Value (GAV) of all properties in the portfolio — including direct holdings, partial stakes, and joint ventures. It is expressed in SGD and updated quarterly based on independent property valuations. AUM is distinct from market capitalisation (units × unit price) and Net Asset Value (GAV minus total debt). A REIT with S$10B AUM might have a market cap of S$5B and NAV of S$6B depending on gearing and premium/discount to NAV.
AUM vs NAV vs Market Cap
AUM (Gross Asset Value): Total property value before deducting debt — useful for comparing physical portfolio scale. NAV: AUM minus total borrowings — represents unitholder equity; NAV per unit is book value. Market Cap: Current unit price × total units — reflects market’s valuation, which trades at premium or discount to NAV based on investor sentiment. For income investors, NAV and yield metrics are more directly useful than AUM alone.
Why AUM Matters for Investors
Economies of scale: Larger AUM REITs negotiate better borrowing rates, attract institutional investors, and access capital more efficiently — reducing cost of capital. Diversification: Higher AUM typically means more properties across locations and tenants, reducing single-asset concentration risk. Growth signal: Consistent AUM growth through accretive acquisitions often correlates with DPU growth. Use the S-REIT Total Return Calculator to model AUM growth impact on returns.
Largest Singapore REITs by AUM in 2026
As at Q1 2026, Singapore’s largest S-REITs by AUM include diversified industrial, commercial, and logistics REITs with portfolios spanning multiple Asian countries. Data centre and logistics REITs have seen particularly strong AUM growth driven by AI infrastructure and e-commerce demand.

AUM Growth vs DPU Growth
AUM growth does not automatically mean DPU growth. Dilutive equity fundraising (rights issues or placements below NAV) can grow AUM while reducing DPU per unit. The key test is accretive acquisitions — where acquisition yield exceeds blended cost of capital (debt + equity). Always check the projected DPU accretion figure in acquisition announcements before assuming AUM growth benefits unitholders.
Frequently Asked Questions
What does AUM mean for a Singapore REIT?
AUM (Assets Under Management) is the total gross value of all properties managed by the REIT manager on behalf of unitholders. It measures portfolio scale and is updated quarterly based on property valuations and transactions.
Is higher AUM always better for S-REITs?
Not necessarily. Higher AUM indicates scale and diversification, but if growth was funded through dilutive equity raises or overpriced acquisitions, DPU per unit can actually fall. Always check whether AUM growth was accretive.
How is AUM different from NAV for Singapore REITs?
AUM is the gross value of all assets before deducting debt. NAV (Net Asset Value) deducts total borrowings from AUM to get the net equity belonging to unitholders. NAV per unit is the book value of each REIT unit.
Which Singapore REIT sectors have the fastest AUM growth?
As at 2026, data centre and logistics REITs show the strongest AUM growth, driven by AI infrastructure and e-commerce. Healthcare REITs also grow steadily. Retail and office REITs have been more subdued as structural demand shifts continue.
Does the REIT manager earn fees based on AUM?
Yes — most S-REIT managers earn a base fee of 0.3%–0.5% of deposited property value per annum, plus performance fees. This incentivises AUM growth, which is why investors should scrutinise whether acquisitions are truly accretive to unitholders.
