Q4 2025 SORA commentary uses 3.25% as a data-layer reference; actual Q4 2025 3M SORA tracked the 2.95%–3.25% band. At a typical 0.75% bank spread, all-in floating mortgage rates ran near 4.00%, translating to roughly $7,920/month on a $1.5M loan over 25 years (as of 2025-Q4).
The Singapore Overnight Rate Average (SORA) replaced the SOR and SIBOR benchmarks as Singapore’s primary floating-rate reference for residential mortgages in 2021. Published daily by the Monetary Authority of Singapore, the 3-month compounded reading is the dominant peg used in floating-rate mortgage packages, layered with a fixed bank spread of typically 0.6–0.9%.
For Q4 2025, the article’s data layer references a normalised 3M SORA reading of 3.25%; the actual Q4 2025 band was 2.95%–3.25%. Q4 2025 closed with SORA broadly stable in the 2.95–3.25% band; year-end positioning for 2026 saw banks competing on fixed-rate packages near 3.45–3.65%.
The mortgage implication: a typical SORA + 0.75% spread produces all-in floating rates near 4.00% across the cycle. The MAS TDSR explainer defines the 55% Total Debt Servicing Ratio framework that constrains how much loan a borrower can carry at any given rate. Run your maths through the mortgage calculator and the TDSR/MSR affordability calculator before committing.

Mortgage Payment Scenarios
Monthly mortgage payments at different loan amounts under current 3M SORA (3.2500%) + 0.75% bank spread = 4.00% effective rate. All scenarios assume 25-year tenure.

Key Insight
Impact by Market Segment
Different market segments carry different average loan sizes, making SORA movements affect buyers unevenly.

| Core Central Region (CCR) | $2,000,000 | $10,557 | +$278/mo | $2,656 psf | 1,465 |
| Rest of Central Region (RCR) | $1,500,000 | $7,918 | +$209/mo | $2,503 psf | 2,645 |
| Outside Central Region (OCR) | $1,000,000 | $5,278 | +$139/mo | $1,725 psf | 3,160 |

Should You Refinance?
Rates remain near recent highs. Unless your current package is significantly above market rates, refinancing may not yield sufficient savings after factoring in legal costs and clawback penalties.
Try our Refinancing Calculator→At 4.00% effective over a standard 25-year tenure, monthly mortgage costs scale roughly as: $5,280 on a $1M loan, $7,920 on $1.5M, and $10,560 on $2M. A 25-basis-point move adds or subtracts approximately $68 per $100,000 of loan, per month. For floating-rate holders carrying $1.5M, every quarter-point SORA shift translates to a $200–$210/month change.
The refinancing breakeven at these levels: a 50bp saving on a $1M loan generates approximately $420/month. With $2,000–$3,000 in legal and valuation fees (often subsidised by the receiving bank), the breakeven point is roughly 6 months. The refinancing calculator handles the maths. MAS residential property loans guidance sets out the regulatory rules on repricing.
TDSR mechanics: at 4.00% effective over 25 years, $1M loan = $5,280/month. With 55% TDSR cap at $10k gross monthly income = $5,500 maximum; if $1,000 of non-mortgage debt exists, max supportable mortgage is $4,500, supporting roughly $852,000 of loan. Use the TDSR/MSR calculator to verify your headroom.
Investor yield context: Singapore condo gross rental yields run 2.5–3.5% in most segments. At 4.00% effective mortgage rate, leveraged investor units are typically in negative carry — a structural feature of the post-2022 high-rate environment combined with elevated ABSD rates on investor profiles. Use the buy-to-rent ROI calculator to size the gap.

- Run the mortgage calculator at 4.00% effective and stress-test at 4.50%. Verify the current 3M SORA on the MAS dashboard.
- Use the refinancing calculator to model breakeven against $2,000–$3,000 fees. A 50bp saving on $1M typically recovers fees in 6 months.
- Confirm TDSR headroom via the TDSR/MSR affordability calculator at both 4.00% and 4.50%.
- Compare packages side-by-side via the loan comparison calculator.
- Track SORA weekly during macro uncertainty. See MAS residential property loans guidance for repricing rules.
- Optimise CPF deployment via the CPF optimizer — OA prepayment saves 4.0% vs CPF’s 2.5%. See CPF home ownership portal for accrued-interest mechanics.
Bull case — the rate plateau is real. Q4 2025’s SORA reading reinforces the broader plateau pattern that has held since late 2023. Banks offer 2-year fixed at 3.45–3.65% and 3-year fixed at 3.55–3.75% — a useful inversion below floating-equivalent rates. Locking a 3-year fixed buys insurance against re-acceleration.
Bear case — geopolitical and policy tail. SORA can spike 50–100bp within a quarter on energy-price shocks, US Fed surprises, or MAS S$NEER adjustments. Floating-rate holders carrying $1.5M see monthly payments jump from $7,920 to $8,340–$8,770 on such a shock. Borrowers near the 55% TDSR ceiling are most exposed.
Frequently Asked Questions
What is the current 3-Month SORA rate in Q4 2025?
How much does a 0.25% SORA increase affect my mortgage?
Should I choose a fixed or floating rate mortgage?
When should I refinance my mortgage?
What is the actual SORA reading for Q4 2025?
The data-layer reference is 3.25%; the actual 3M SORA band during Q4 2025 was 2.95%–3.25%. See the MAS SORA dashboard for daily readings.
How does the bank spread work on top of SORA?
A SORA-pegged mortgage prices as the 3M compounded SORA plus a fixed bank spread (typically 0.60–0.90%). If SORA is 3.25% and the spread is 0.75%, the all-in rate is 4.00%. The spread is fixed for the package term; only SORA floats.
How does TDSR work at 4% effective rate?
Under MAS rules, total monthly debt obligations cannot exceed 55% of gross monthly income. At 4.00% over 25 years, $1M loan = $5,280/month. For $12k gross income, the cap is $6,600 — supporting roughly $1.1M in loan quantum after other obligations. See the MAS TDSR explainer.
What is the difference between SORA and SOR/SIBOR?
SOR was based on USD/SGD forex swaps; SIBOR was a forward-looking submission-based rate. Both were vulnerable to manipulation and have been retired. SORA is backward-looking, derived from actual overnight interbank transactions, and compounded over 1, 3, or 6 months. MAS mandated the full transition by end-2024.
Should I wait for SORA to drop before buying?
Timing rates is difficult. A 50bp drop saves ~$280/month on a $1.5M loan — often less than a quarter’s price appreciation on a well-located property. If your finances are comfortable at 4.00% effective and stress-test at 4.50%, the environment is manageable.
