In the context of Singapore REITs, Assets Under Management (AUM) refers to the total value of all properties and real estate assets managed by the REIT manager on behalf of unitholders. AUM is a key measure of a REIT’s scale, diversification, and growth trajectory — larger AUM generally indicates a more established REIT with greater income stability. Understanding AUM helps Singapore investors compare S-REITs across sectors and assess their long-term growth potential.

How AUM Is Calculated for Singapore REITs
For S-REITs, AUM typically equals the total gross asset value (GAV) of all properties in the portfolio, including both direct property holdings and any partial stakes in properties or joint ventures. It is expressed in Singapore dollars and updated quarterly based on independent property valuations and acquisitions or divestments during the period.
AUM is distinct from market capitalisation (total units × unit price) and net asset value (GAV minus total debt). A REIT with S$10 billion in AUM might have a market cap of S$5 billion and a NAV of S$6 billion, depending on its gearing and unit price premium or discount.
AUM vs Net Asset Value vs Market Cap
These three metrics measure different aspects of a REIT’s size:
AUM (Gross Asset Value): Total value of all properties before deducting debt. Useful for comparing the physical scale of property portfolios across REITs.
Net Asset Value (NAV): AUM minus total borrowings. Represents the unitholders’ equity in the portfolio. The NAV per unit is the book value of each unit.
Market Capitalisation: Current unit price × total units outstanding. Reflects the market’s valuation, which can trade at a premium or discount to NAV depending on investor sentiment and yield expectations.
For income investors, NAV and yield-based metrics are more directly useful than AUM. But AUM is important for assessing REIT scale and the manager’s ability to source deals and negotiate debt terms.
Why AUM Matters for S-REIT Investors
Economies of scale: Larger REITs with higher AUM can negotiate better borrowing rates, attract institutional investors, and access capital markets more efficiently. This reduces the cost of capital and can support higher distributions.
Diversification: Higher AUM typically means more properties across more locations or tenants, reducing concentration risk. A REIT with only 3 properties is far more exposed to single-asset risk than one with 30 properties.
Growth runway: AUM growth over time — through acquisitions, asset enhancement initiatives (AEIs), or development completions — indicates that the REIT manager is actively deploying capital to grow the portfolio. Consistent AUM growth often correlates with DPU (distribution per unit) growth.

Largest S-REITs by AUM in Singapore
As at Q1 2026, Singapore’s largest S-REITs by AUM include several mega-cap diversified and industrial REITs. CapitaLand Integrated Commercial Trust (CICT), Mapletree Pan Asia Commercial Trust (MPACT), and Frasers Logistics & Commercial Trust (FLCT) are among the largest by total GAV, each with portfolios spanning multiple Asian countries.
Data centre and logistics REITs have seen particularly strong AUM growth in recent years, driven by robust demand from e-commerce and technology sectors. Retail and office REITs have faced more muted AUM growth as hybrid work and online shopping reshape demand for physical space.

AUM Growth vs DPU Growth: What to Prioritise
AUM growth does not automatically translate into DPU growth. If a REIT grows AUM through highly dilutive equity fundraising (rights issues or placements at a price below NAV), unitholders may actually see DPU per unit decline even as the total portfolio grows.
The ideal scenario is accretive acquisitions — where the acquisition yield (property income ÷ purchase price) exceeds the cost of financing (blended debt + equity cost). In this case, AUM growth drives both NAV and DPU higher.
Always examine the acquisition announcement for the projected DPU accretion (or dilution) figure — this tells you directly whether AUM growth is beneficial for unitholders.
Frequently Asked Questions
What does AUM mean for a Singapore REIT?
AUM (Assets Under Management) for a Singapore REIT refers to the total gross value of all properties in its portfolio, managed by the REIT manager on behalf of unitholders. It measures the portfolio’s physical scale and is updated quarterly based on valuations and transactions.
Is higher AUM always better for a REIT?
Not necessarily. Higher AUM indicates scale and diversification, but if growth was funded through dilutive equity raises or overpriced acquisitions, it can hurt DPU per unit. Always check whether AUM growth was accretive — i.e., it added to DPU rather than diluting it.
How does AUM differ from NAV for Singapore REITs?
AUM is the gross value of all assets before deducting debt (also called Gross Asset Value or GAV). NAV (Net Asset Value) deducts total borrowings from AUM to arrive at 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 have shown the strongest AUM growth, driven by AI infrastructure investment and e-commerce demand. Healthcare REITs have also grown 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 management fee calculated as a percentage of AUM (typically 0.3%–0.5% per annum of deposited property value) plus a performance fee. This structure incentivises managers to grow AUM, which is why investors should scrutinise whether acquisitions are truly accretive to unitholders.
