MAS: about about 4,000 Singapore home-loan households could run short of cash in a severe stress scenario

Implications for lenders

For lenders in Singapore, the stress test points to a small segment, about about 4,000 households, where an income shock combined with higher mortgage rates may turn into arrears, so early-warning monitoring and restructuring options for that profile can matter more than portfolio-wide tightening. With personal loans to disposable income at 0.31x, unsecured lenders may want to watch applicants who also carry large housing loans.

Implications

Facts

In a written parliamentary reply published on 7 October 2026, MAS chairman Gan Kim Yong said MAS's latest stress test finds that most borrower households with housing loans from financial institutions would remain resilient under a severe adverse scenario. Around about 1% of these borrowers, estimated at about 4,000 households, could face cash shortfalls, with monthly spending above income and too little savings to cover the gap. ¹ The reply says this share has been relatively stable across annual stress tests, and that the figures show who could come under stress if the scenario occurred, not households under stress today.

MAS's Financial Stability Review 2026, published in September, sets out the scenario: household income falls by around 10%, unemployment rises and mortgage rates rise by 200 bps. ² The review describes the vulnerable group as mainly middle-aged HDB dwellers with lower incomes, plus some middle-income borrowers with large private housing loans.

Current indicators in the review are benign. Household debt to personal disposable income was 1.08x in Q2 2026 (1.04x in Q2 2025), against a ten-year average of 1.26x. ³ Personal loans to disposable income were 0.31x (0.28x a year earlier; 10-year average 0.35x), and credit card rollover balances were 2.5% of disposable income, up marginally over the past year. ⁴ The housing loan NPL ratio was 0.2% (10-year average 0.35%). ⁵ Household financial assets grew 9.5% year on year, ahead of liabilities at 8.3%.

On support, the reply says financial institutions monitor repayment and engage borrowers who show early signs of stress; HDB homeowners in arrears can approach HDB or their bank to discuss restructuring; and borrowers already in difficulty can seek help from Credit Counselling Singapore. MAS urged households to borrow prudently and keep savings buffers given an uncertain outlook for interest rates.

Analysis

The vulnerable group is defined by a combined shock, not by today's repayment burden. Rates have moved the other way: fixed-rate bank mortgage packages were around 1.5% in Q2 2026, around 2.5% in Q2 2025. ⁶ The stress test therefore measures how much room borrowers would lose if rates reversed while incomes fell.

Over time, leverage is edging up from a low base: debt to disposable income moved from 1.04x in Q2 2025 to 1.08x, and personal loans grew faster than the total (0.28x a year earlier; 10-year average 0.35x). Revolving card debt is also higher in money terms, with balances that incur interest at SGD 9.64bn (SGD 8.82bn in Q2 2025). ⁷

The policy tools differ across financial centres. Singapore's total debt servicing ratio for mortgages is computed with a medium-term interest-rate floor, while Hong Kong since August 2026 caps licensed money lenders' debt servicing ratios for low-income borrowers at 35%–40%. ⁸ Both approaches limit repayment burdens, which matters most for the segment the MAS stress test identifies: lower-income borrowers with thin buffers.

Counterpoints and uncertainties

The household count is a model estimate under one scenario; MAS gives no share of loan balances affected, so the exposure in money terms is not public. If rates fall further the vulnerable group may shrink, while a sharper rise in unemployment than assumed would enlarge it. The FSR aggregates are national and do not show borrowers who hold debts across several lenders.
