Bishan-Toa Payoh MP Saktiandi Supaat pressed the Government on Monday to spell out how sustained rises in United States Treasury yields could flow through to Singapore home loans, even as local benchmark rates have moved more slowly than in other markets.
In an oral reply filed for the 7 October sitting, Minister for National Development and MAS deputy chairman Chee Hong Tat said Singapore’s interest rates are market-determined and have not climbed as sharply as elsewhere. The prevailing 10-year Singapore Government Securities yield stood at 2.5%, he noted, against a 10-year average near 2.2%. The discount of 10-year SGS to 10-year US Treasuries had widened from about 170 basis points in January 2025 to about 250 basis points by September 2026.
Mr Chee said three-month compounded SORA, a key reference for floating mortgages, was around 1.2%, below its 10-year average of 1.5%. Credit growth remained firm, loan quality sound and banks well capitalised, according to MAS stress tests cited in the reply.
What the safeguards already do
Households are not unprotected on paper. The Total Debt Servicing Ratio caps total monthly debt repayments at 55% of income. For public housing purchases, the Mortgage Servicing Ratio limits mortgage payments to 30% of income. Banks must assess affordability at a 4% mortgage rate even when market quotes are lower.
About 60% of HDB households with outstanding loans hold concessionary HDB loans pegged to the CPF Ordinary Account rate, which Mr Chee said provides more stability than purely market-linked mortgages when global yields spike.
MAS also works with lenders to monitor repayment performance and encourage early engagement. In September 2026 the Government raised its risk-share on eligible Enterprise Financing Scheme loans from 50% to 70% to support firms facing tighter credit.
Why MPs still asked
Mr Saktiandi’s questions focused on borrowers who sit just inside the affordability buffers. A slower pass-through in Singapore does not mean zero pass-through, especially for buyers on SORA-linked packages who refinanced during the low-rate window.
Parliamentary records from the same sitting week show separate questions on lower-income HDB borrowers at risk of negative cash flow, with ministers pointing to loan restructuring, employment support and temporary financial aid. The politics desk read that as a signal that rate risk and income risk are being handled as linked problems, not separate spreadsheets.
What to watch next
No new housing policy was announced in the reply. The actionable line for households is unchanged: stress-test your own budget at higher rates, and approach your lender before arrears accumulate. For investors, the widening SGS–Treasury gap is the local story inside the global bond shock — Singapore fiscal credibility is doing work, but floating-rate homeowners still live on SORA, not Washington’s auction results.
SORA-linked borrowers
Floating-rate packages tied to three-month compounded SORA reset on a quarterly rhythm. A borrower who locked in during 2024’s softer prints may still face higher absolute payments if SORA grinds higher even while the SGS–Treasury gap widens. Mortgage brokers say refinance inquiries rose in September when US long yields jumped, even though local fixed-rate promotions continued for qualified applicants.
HDB’s concessionary loan peg gives a different profile: payments move with the CPF Ordinary Account rate, which policymakers adjust on a separate calendar from global bond markets. That split means parliamentary answers about “Singapore borrowing costs” land differently in a Bukit Batok five-room flat than in a downtown condo on a bank board rate.
Enterprise support is the other half of Mr Chee’s reply. The higher Enterprise Financing Scheme risk-share is aimed at firms whose working capital lines price off the same rate complex as household loans. If credit tightens for SMEs, household income shocks can follow — another reason MPs asked for a joined-up picture rather than a bond-market lecture alone.
