Context Post-pandemic cost-of-living pressures, elevated interest rates, HDB and private property market stress
- Introduction and Background
Singapore presents a compelling and analytically distinct case for studying mortgage delinquency dynamics. As a city-state with one of the world’s highest rates of home ownership — approximately 90% of resident households occupy owner-occupied dwellings, predominantly through the Housing & Development Board (HDB) public housing scheme — the stability of mortgage repayment behaviour is of critical macroprudential importance. Any deterioration in mortgage servicing capacity has wide systemic implications, given the extent to which household wealth and financial identity are bound to residential property.
Globally, data from credit scoring institutions such as VantageScore in the United States have shown early-stage mortgage delinquencies rising by nearly 30.9% year-on-year as of January 2026, driven by sustained cost-of-living pressures even as headline inflation has moderated from 2022 peaks. While Singapore’s mortgage market differs structurally from the U.S. in several material respects — including the predominance of HDB loans, Central Provident Fund (CPF) usage for debt servicing, and macroprudential guardrails such as the Total Debt Servicing Ratio (TDSR) — analogous pressures are observable in the Singapore context.
This case study examines the drivers, scenarios, outlook, and policy responses pertaining to rising mortgage stress in Singapore, drawing on the intersection of housing policy, macroeconomic conditions, and household financial behaviour.
- Singapore-Specific Scenarios Driving Mortgage Stress
2.1 Interest Rate Transmission Through HDB Floating-Rate Loans
The Singapore Interbank Offered Rate (SIBOR) and its successor, the Singapore Overnight Rate Average (SORA), form the benchmark for floating-rate mortgages issued by commercial banks. Between 2022 and 2024, the Monetary Authority of Singapore (MAS) tightened monetary policy via Singapore Dollar Nominal Effective Exchange Rate (S$NEER) appreciation, which fed through to domestic interest rates. Commercial bank mortgage rates rose from approximately 1.3% per annum in early 2022 to above 4.0% by late 2023, before moderating somewhat in 2025.
Households that refinanced or originated loans at peak rates faced materially higher monthly instalments. For instance, a household with an outstanding mortgage of SGD 500,000 refinancing from 1.3% to 4.0% over a 25-year tenor would experience an increase in monthly repayment from approximately SGD 1,940 to SGD 2,638 — an increase of approximately SGD 698 per month, or roughly 36%. For median-income Singaporean households earning approximately SGD 9,500 per month (2024 MOM data), this increment represents a non-trivial consumption compression.
2.2 CPF Shortfall and Cash-Flow Stress
Singapore’s CPF Ordinary Account (OA) ordinarily serves as a buffer for mortgage servicing, with mandatory contributions from both employee and employer channeled into housing repayment. However, when CPF balances are exhausted — as may occur in households that purchased at elevated price points or with large outstanding balances — borrowers must service loans from cash income. This creates a discontinuity in repayment capacity.
A scenario of particular concern involves younger households who purchased resale HDB flats or private condominiums in the 2021–2022 period at historically elevated prices. These cohorts face the dual burden of high absolute loan quantum and elevated interest rates, compressing their CPF balances faster than anticipated and increasing cash-servicing obligations earlier in the loan lifecycle.
2.3 Cost-of-Living Pressures Reducing Residual Income
Singapore’s core inflation, as measured by MAS, peaked at approximately 5.5% in early 2023 before declining to around 2.9% in 2025. However, the cumulative price-level effect remains significant. Categories with above-average price increases include:
Food and beverage costs at hawker centres and food courts, driven by rental and ingredient inflation
Utilities and electricity tariffs, which rose substantially following global energy market disruptions in 2022
Childcare and education-related expenses, including enrichment and school fees
Healthcare and veterinary costs, which have trended structurally upward
Private transport costs including car ownership and ride-hailing fares
For homeowners — particularly those in the sandwiched middle class who do not qualify for government assistance but face these structural cost increases — residual income after mortgage repayment has compressed. This is the proximate mechanism by which households begin to exhibit early-stage delinquency behaviour, missing one or two monthly instalments before entering formal arrears.
2.4 Retrenchment Risk and Gig Economy Vulnerability
Global technology sector retrenchments in 2023–2024 affected Singapore-based employees in multinational corporations, particularly in financial services technology, e-commerce, and professional services. While Singapore’s overall unemployment rate remained low (approximately 2.1% in 2025), involuntary job displacement among PME (Professionals, Managers, and Executives) cohorts — who disproportionately hold larger mortgages on private properties — created pockets of repayment stress.
Additionally, the growth of self-employed and gig-economy workers, whose CPF contributions are not mandated for the employer component, creates structural vulnerability in CPF-based mortgage servicing for this demographic.

- Outlook: Three Scenarios for 2026–2027
4.1 Base Case: Managed Soft Landing
Under the base-case scenario, global interest rates continue on a gradual easing trajectory through 2026, with SORA-based mortgage rates declining to approximately 2.5–2.8% by end-2026. Singapore’s GDP growth remains resilient at 2.0–2.5%, supported by manufacturing and financial services. Household incomes track modest real wage growth, and the HDB’s Build-To-Order (BTO) pipeline alleviates pressure on the resale segment.
Under this scenario, early-stage mortgage delinquencies stabilise below 1% of borrowers, and non-performing loan ratios for residential mortgages remain well within MAS’s prudential comfort zone. The financial system absorbs the adjustment without systemic stress.
4.2 Adverse Case: Prolonged Elevated Rates and Recessionary Shock
Should global trade disruptions — including an escalation of U.S.-China tariff conflict or a regional financial contagion event — dampen Singapore’s externally-oriented economy, GDP growth could contract to below 1% or turn negative. In such a scenario, retrenchment rates among PMEs rise materially, consumer sentiment deteriorates sharply, and households begin to draw down precautionary savings.
Under this adverse scenario, early-stage mortgage delinquencies could approach 2–3% of borrowers by end-2027, and the non-performing residential loan ratio could rise to 1.0–1.5%, levels unseen since the 2009 Global Financial Crisis aftermath. Property price corrections of 8–12% in the private segment are plausible, triggering negative equity for a subset of high-LTV borrowers, particularly those who entered the market at 2021–2022 peak valuations.
4.3 Upside Case: Rapid Rate Normalization and Wage Growth
If global inflationary pressures dissipate faster than anticipated and central banks, particularly the U.S. Federal Reserve, accelerate rate cuts through 2026, SORA could normalise toward 1.5–2.0%. Combined with Singapore’s strategic positioning in AI and advanced manufacturing drawing high-value foreign investment, real wage growth could outpace cost increases, strengthening household balance sheets.
Under this upside scenario, delinquency trends reverse, property transaction volumes recover, and the HDB resale market sees renewed demand from upgraded buyers. Financial system resilience is reinforced, and macroprudential tools may be selectively relaxed.
- Impact Analysis
5.1 Household-Level Impact
At the household level, mortgage stress manifests in multiple reinforcing dimensions. Consumption spending is curtailed, reducing contributions to the domestic economy. Precautionary savings accumulate at the expense of investment and retirement adequacy. In households where mortgage servicing stress is acute, asset liquidation — including the sale of investment properties or CPF Investment Scheme holdings — may be accelerated at sub-optimal valuations.
For HDB owners, the inability to service a concessionary HDB loan triggers escalation mechanisms that can ultimately lead to compulsory acquisition of the flat by HDB, with proceeds used to discharge the outstanding loan. This represents not only a financial loss but a significant social disruption, as public housing tenure is deeply embedded in Singaporean household identity and intergenerational wealth transfer expectations.
5.2 Banking Sector Impact
Singapore’s three major domestic banks — DBS, OCBC, and UOB — carry significant residential mortgage exposures. As of 2024, housing loans constituted approximately 25–30% of total loan books across these institutions. A meaningful deterioration in residential mortgage quality would necessitate increased loan loss provisioning, compressing net interest margins and return on equity.
However, Singapore’s banks are among the world’s best capitalised, with Common Equity Tier 1 (CET1) ratios well above Basel III minimums. This capital adequacy provides substantial headroom to absorb credit losses before systemic solvency is threatened. The greater risk is contagion through confidence channels — falling property valuations reducing collateral values across the loan book — rather than direct credit losses from mortgage defaults alone.
5.3 Property Market and Wealth Effect Impact
Singapore’s property market is structurally supply-constrained, given the city-state’s limited land area. This fundamentally mitigates the risk of sustained price collapse. Nevertheless, if forced selling by distressed homeowners becomes more prevalent, transaction volumes increase at depressed price points, creating a negative price spiral that could erode household net worth broadly.
Given that property assets constitute the single largest component of most Singaporean household balance sheets — often exceeding 50–60% of total wealth — even moderate property price declines have an outsized negative wealth effect. This reduces consumer confidence, discretionary spending, and, in turn, domestic demand, creating a second-order macroeconomic drag.
5.4 Social and Equity Impact
The social dimension of mortgage stress in Singapore must be considered within the context of the Housing Development Board’s foundational role as a vehicle for social equity and national cohesion. Loss of HDB ownership is not merely a financial event; it disrupts community ties, school proximity arrangements, and intergenerational housing plans. Concentrated mortgage stress in lower-income cohorts — who hold proportionally less financial buffers — risks widening socioeconomic disparities and creating spatial concentrations of housing vulnerability.
- Policy Solutions and Recommendations
6.1 MAS Macroprudential Calibration
The MAS should continue to monitor TDSR and Loan-to-Value (LTV) ratio effectiveness as real-time stress indicators. Should early-stage delinquency rates breach a defined threshold (e.g., 2% of residential borrowers), a pre-emptive relaxation of TDSR thresholds or LTV caps for genuine owner-occupier distressed refinancing should be considered. This is distinct from a broad macroprudential loosening that would stimulate speculative demand.
Targeted mortgage relief instruments — analogous to the Mortgage Servicing Ratio relief extended during COVID-19 — should be institutionalised as a standing policy tool, activated by a pre-defined delinquency trigger rather than requiring ad hoc legislative action.
6.2 HDB Financial Counselling and Early Intervention
HDB’s existing Financial Assistance Scheme should be proactively marketed to households exhibiting early-stage stress indicators — missed or partial payments — rather than relying on borrower self-identification. Partnerships with Credit Counselling Singapore (CCS) should be deepened, with referral pathways embedded in HDB’s arrears management process.
A pilot programme for voluntary restructuring of HDB concessionary loans — allowing a temporary shift to interest-only payments for a defined period of up to 24 months, subject to income verification — could serve as a meaningful buffer for households experiencing transient income disruption (e.g., retrenchment, medical emergency).
6.3 CPF Policy Refinements
Policymakers should assess whether the CPF Ordinary Account withdrawal rules appropriately balance retirement adequacy objectives with housing financing flexibility. A targeted enhancement could allow distressed owner-occupiers to temporarily increase the proportion of OA contributions channeled to mortgage servicing, above the current limits, during approved hardship periods. This preserves the household’s payment record while maintaining the CPF system’s integrity.
6.4 Banking Sector Supervisory Guidance
MAS supervisory guidance should encourage domestic banks to adopt proactive customer outreach to borrowers who have missed one instalment, before entry into formal arrears. International evidence strongly supports early intervention as the most cost-effective delinquency resolution mechanism. Banks should be incentivised — potentially through regulatory capital treatment — to offer restructuring solutions at the one-to-two month delinquency stage rather than escalating to recovery processes.
6.5 Targeted Cost-of-Living Support
Beyond the housing financing domain, the government’s broader toolkit of targeted transfers — Community Development Council (CDC) vouchers, Assurance Package offsets, and utilities rebates — should be calibrated with explicit consideration of their indirect role in sustaining mortgage repayment capacity among lower-to-middle-income households. Reducing discretionary cost pressures in food, utilities, and transport directly augments residual income available for debt servicing.
- Conclusion
Singapore’s mortgage market, while structurally resilient by international comparison, is not insulated from the macroeconomic forces driving early-stage delinquency trends globally. The confluence of elevated interest rates, cumulative cost-of-living inflation, and pockets of employment vulnerability has begun to exert measurable pressure on household balance sheets, particularly among middle-income cohorts that lack access to targeted government assistance but face material increases in debt-servicing obligations.
The key analytical insight is that the risk is not one of immediate systemic crisis — Singapore’s macroprudential framework, banking sector capitalisation, and housing market structure provide substantial buffers — but rather of gradual, broad-based financial fragility that increases the economy’s vulnerability to exogenous shocks. The rise of early-stage delinquencies is most usefully interpreted as a leading indicator of systemic stress rather than a current crisis, precisely the stage at which preventive policy intervention is most effective and least costly.
A multi-pronged policy response — encompassing macroprudential calibration, CPF flexibility, proactive bank-level early intervention, and targeted household support — represents the optimal framework for managing this transition while preserving Singapore’s long-established tradition of high homeownership rates and financial system stability.
