Weighted Average Lease Expiry (WALE)
How WALE Signals Income Stability for Singapore REIT Investors â Singapore investing guide with key metrics, examples and 2026 data.
Weighted Average Lease Expiry (WALE) is a metric used to assess the income stability of a property portfolio by measuring the average remaining lease term across all tenants, weighted by their contribution to the REIT’s gross rental income (GRI) or net lettable area (NLA). A higher WALE means leases are locked in for longer â providing more predictable and stable rental income for S-REIT investors.

What Is WALE?
Weighted Average Lease Expiry (WALE) â sometimes called Weighted Average Lease to Expiry (WALTE) or Weighted Average Unexpired Lease Term (WAULT) in some markets â is a standard metric reported by S-REITs in their quarterly and annual financial results. It tells investors how long, on average, existing tenants are contracted to stay in the REIT’s properties.
The “weighted” aspect is critical: a tenant who contributes 20% of gross rental income (GRI) has 20 times more influence on the WALE figure than a tenant who contributes 1% of GRI. This income-weighted approach (WALE by GRI) is the most commonly used version for S-REIT analysis, though some REITs also disclose WALE by net lettable area (NLA), which gives equal weight to space rather than income.
WALE is expressed in years. A WALE of 5.0 years means that, on average weighted by income, the existing leases across the portfolio won’t expire for another 5 years. A WALE of 1.5 years indicates that a large proportion of income is at risk of non-renewal in the near term â requiring management to re-lease properties and introducing income uncertainty.
WALE is closely related to other occupancy and lease metrics but differs from occupancy rate (which measures what proportion of space is currently leased) â WALE measures how long those leases last.
How It Works
To calculate WALE by gross rental income:
WALE = Σ (Remaining Lease Term à Tenant GRI as % of Total Portfolio GRI)
Example:
A retail REIT has three major tenants:
| Tenant | GRI Contribution | Remaining Lease | Weighted |
|---|---|---|---|
| NTUC FairPrice | 40% | 8 years | 3.2 yrs |
| Smaller retailer A | 35% | 3 years | 1.05 yrs |
| Smaller retailer B | 25% | 2 years | 0.5 yrs |
WALE = 3.2 + 1.05 + 0.5 = 4.75 years
The large anchor tenant (NTUC FairPrice) significantly boosts the WALE because of its dominant GRI weighting and long remaining lease. This is why anchor tenants matter enormously for retail and industrial REIT WALE stability.
WALE for S-REITs in Singapore
WALE benchmarks differ significantly by S-REIT sub-sector, reflecting the typical lease structures of different property types in Singapore:
| Sector | Typical WALE (by GRI) | Key Driver |
|---|---|---|
| Industrial (logistics/hi-spec) | 3â6 years | Long built-to-suit leases |
| Commercial/office | 2â5 years | 3-year typical office leases |
| Retail malls | 1.5â4 years | Anchor vs specialty mix |
| Healthcare/data centres | 10â25+ years | Long master leases |
| Overseas/pan-Asia | Varies widely | Market-specific norms |
Singapore industrial REITs like Mapletree Logistics Trust and Mapletree Industrial Trust often carry WALEs of 3â5 years for their Singapore assets, underpinned by logistics and data centre tenants. Healthcare REITs like Parkway Life REIT have exceptionally long WALEs (often 15â20+ years) because of master lease agreements with hospital operators like IHH Healthcare.
When comparing REITs within the same sub-sector, a higher WALE generally signals greater near-term income predictability â which typically supports a higher valuation and lower distribution yield premium.

Real-World Examples
Mapletree Industrial Trust (MIT) â Q3 FY2025/26:
MIT reported a WALE of approximately 4.1 years by GRI for its Singapore portfolio and 5.3 years for its US data centre assets. The longer WALE for data centres reflects the 10â15 year typical lease terms with hyperscale tenants like Microsoft and Amazon Web Services â locking in stable, growing income for years. This is a key reason data centre REITs command premium valuations relative to traditional industrial REITs.
CapitaLand Integrated Commercial Trust (CICT) â Q4 2025:
CICT’s retail assets in Singapore showed a WALE of approximately 2.0â2.5 years, reflecting the shorter lease terms typical of Singapore retail malls. This lower WALE is normal for retail REITs and is balanced by CICT’s strong occupancy rates (94%â97%) and brand-name anchor tenants like FairPrice, H&M, and NTUC. Short WALE is only a risk if occupancy falls â at near-full occupancy, lease renewals convert to new income at market rates.
Why It Matters for Investors
For Singapore retail investors evaluating S-REITs for dividend income, WALE is a critical indicator of near-term Distribution Per Unit (DPU) stability. A REIT with a very short WALE (under 1.5 years) faces significant lease expiry risk â if a large tenant doesn’t renew or downsizes, rental income falls and DPU gets cut. This is especially relevant for office REITs in a post-COVID environment where tenants are consolidating space.
WALE should always be read alongside occupancy rate, tenant concentration, and rent reversion expectations. A REIT with a 2-year WALE but a proven track record of 95%+ occupancy and positive rent reversions (rents going up at renewal) is less risky than the raw WALE number suggests. Conversely, a REIT with a 5-year WALE but a single tenant representing 80% of GRI concentrates lease expiry risk despite the long average.
When analysing S-REITs, combine WALE with the gearing ratio, interest coverage ratio, and Net Asset Value (NAV) for a complete financial health picture. Our Dividend Calculator and Retirement Calculator can help you model the impact of REIT income on your long-term wealth plan.
Frequently Asked Questions
What is a good WALE for a Singapore REIT?
A “good” WALE depends on the sub-sector. For industrial and logistics REITs, a WALE above 3 years is generally healthy. For retail REITs, 2+ years is typical given shorter mall lease tenures. Healthcare REITs and those with master leases often have WALEs above 10 years, indicating very long-term income visibility. The key is to compare WALE within the same sub-sector rather than across different property types.
What is the difference between WALE by GRI and WALE by NLA?
WALE by gross rental income (GRI) weights leases by how much income they generate â this is the most important version for investors because it shows the income-risk profile. WALE by net lettable area (NLA) weights leases by physical space, which can differ significantly from GRI-weighted WALE if some tenants pay much higher rent per square foot than others (e.g., premium retail space vs storage). GRI-weighted WALE is generally more meaningful for assessing DPU stability.
Does a low WALE mean a REIT is risky?
Not necessarily. A low WALE is only a risk if accompanied by high vacancy risk or falling market rents. Retail and hospitality REITs typically operate with low WALEs (1â3 years) by sector norm. The risk increases when a low WALE coincides with: high vacancy, deteriorating tenant credit quality, falling market rents, or a single large tenant whose renewal is uncertain. Assess WALE alongside occupancy rate and rent reversion trend for a complete picture.
Where can I find the WALE for a specific S-REIT?
S-REITs disclose WALE in their quarterly earnings presentations and financial statements filed on SGX (sgx.com). It typically appears on the portfolio summary or debt/lease profile slide in the quarterly results slide deck. You can also find WALE data aggregated on financial research platforms like ShareInvestor, Refinitiv, or the SGX’s own REIT data portal.
How does WALE relate to rent reversion for S-REITs?
When leases expire (i.e., as WALE counts down to zero for individual leases), the REIT must re-sign or re-lease the space. If market rents are rising, short WALE can actually be positive â leases renew at higher rates, increasing income. This is called positive rent reversion and boosts DPU. Conversely, if market rents are falling, expiring leases renew at lower rates â negative rent reversion hurts income. WALE combined with rent reversion guidance tells you whether near-term lease expiries are headwinds or tailwinds.
