REIT Fund Size and Market Cap Singapore: Complete Guide 2026
For informational purposes only. Not financial advice.
REIT fund size refers to total assets under management (AUM) of an S-REIT, while market capitalisation is the total market value of its outstanding units. Larger S-REITs tend to offer better liquidity, lower borrowing costs, index inclusion, and greater acquisition capacity.
AUM vs Market Capitalisation: Key Differences
AUM (Assets Under Management) represents the total value of a REIT’s property portfolio at book value. Market capitalisation is calculated as unit price × number of units outstanding. A REIT’s market cap may trade at a premium or discount to its Net Asset Value (NAV), which is essentially the book value of assets minus liabilities per unit.
As at Q1 2026, Singapore’s largest S-REITs by market cap include CapitaLand Integrated Commercial Trust (~S$13B), Ascendas REIT (~S$12B), and Mapletree Logistics Trust (~S$8B). These large-cap REITs form part of the STI (Straits Times Index) and iEdge S-REIT Index.
Why Fund Size Matters for S-REIT Investors
Larger S-REITs benefit from: greater liquidity (easier to buy/sell without moving the unit price), lower cost of capital (can borrow at tighter spreads from banks), index inclusion (institutional buying support), economies of scale in property management, and larger war chest for acquisitions. Smaller REITs may offer higher yields but carry liquidity premium risk.
Index Inclusion and Institutional Ownership
S-REITs included in major indices like the STI, MSCI Singapore Index, or iEdge S-REIT Leaders Index benefit from automatic buying by index-tracking funds. This institutional ownership base provides price support and liquidity. REIT managers actively grow their AUM to reach index inclusion thresholds, which is one reason why S-REITs pursue acquisitions aggressively.
Small-Cap vs Large-Cap S-REITs: Trade-offs
Small-cap S-REITs (market cap below S$500M) may offer higher distribution yields but come with: lower liquidity (wider bid-ask spreads), limited analyst coverage, less access to capital markets, and higher relative management costs. Large-cap S-REITs trade at tighter yields but offer better risk-adjusted returns for most retail investors due to lower liquidity risk and stronger governance.

Frequently Asked Questions
What is REIT AUM vs market cap in Singapore?
AUM is the total value of a REIT’s property assets. Market cap is unit price × units outstanding. They differ because market cap reflects investor sentiment and may trade at a premium or discount to NAV (net asset value). Most major S-REITs are currently trading at or below NAV as at Q1 2026.
Which are the largest S-REITs by market cap in 2026?
The largest S-REITs by market cap include CapitaLand Integrated Commercial Trust (CICT, ~S$13B), Ascendas REIT (~S$12B), Mapletree Logistics Trust (~S$8B), Mapletree Industrial Trust (~S$6B), and Frasers Logistics & Commercial Trust (~S$5B). These form part of the STI and major S-REIT indices.
Why do larger REITs have lower borrowing costs?
Larger REITs have stronger credit profiles, broader lender relationships, and better access to bond markets. This allows them to borrow at tighter spreads over benchmark rates. Lower borrowing costs directly improve distributable income and support DPU sustainability.
Should I invest in small-cap or large-cap S-REITs?
Large-cap S-REITs offer better liquidity, institutional support, and lower borrowing costs, making them suitable for most retail investors. Small-cap S-REITs may offer higher yields but carry liquidity risk and require more active monitoring. A diversified REIT portfolio typically includes a mix of large-cap core holdings with some selective small-cap exposure.
How does index inclusion affect REIT prices?
When a REIT is added to a major index (STI, iEdge S-REIT Leaders), index-tracking ETFs and funds must buy units to match the index. This creates a demand-driven price catalyst. Conversely, removal from an index triggers selling. Investors should monitor index rebalancing announcements for S-REIT investment opportunities.
