The Two Main Rate Types: Fixed and Floating
Singapore home loans are currently offered in two broad formats:
- Fixed-rate packages: The interest rate is locked at a predetermined level for a fixed period — typically 2 or 3 years — regardless of how market interest rates move during that period. After the fixed-rate period ends, the loan typically converts to a floating rate (unless the borrower reprices or refinances).
- Floating-rate (SORA-pegged) packages: The interest rate moves in line with SORA (Singapore Overnight Rate Average), a market benchmark published daily by MAS. SORA-pegged packages are typically expressed as SORA + a spread (e.g., 3-month compounded SORA + 0.80% p.a.). The total rate changes as SORA moves.
Prior to 2024, floating-rate loans were also pegged to SIBOR (Singapore Interbank Offered Rate). SIBOR has been discontinued and all new floating-rate mortgages in Singapore are now SORA-pegged.
Fixed-Rate Packages: How They Work
In a fixed-rate package, the bank commits to a specific rate (e.g., 3.20% p.a.) for the fixed period. The monthly repayment amount is predictable and does not change if SORA rises or falls during the fixed-rate window.
- Lock-in period: Fixed-rate packages almost always come with a lock-in period equal to or slightly longer than the fixed-rate period. Repaying the loan early or refinancing within the lock-in period triggers a prepayment penalty, typically 1.5% of the redeemed amount.
- Rate after the fixed period: When the fixed-rate period expires, the loan typically reverts to the bank's floating rate (often the bank's board rate or a SORA-pegged rate). Borrowers who do not reprice or refinance at this point often end up on a higher revert rate. Setting a calendar reminder to review the loan at the fixed-rate expiry is important.
- Pricing premium for certainty: Fixed-rate loans typically carry a premium over current floating rates to compensate the bank for the interest rate risk it assumes during the fixed period. In a low-rate environment, fixed rates may be priced close to floating rates. When rates are elevated and expected to fall, fixed rates may be noticeably higher than floating rates.
Floating-Rate (SORA-Pegged) Packages: How They Work
SORA is published daily by MAS based on overnight interbank borrowing rates. Most Singapore home loans use the 1-month or 3-month compounded SORA average rather than the overnight rate, which smooths out daily fluctuations.
- Rate moves with market conditions: When SORA rises (typically during monetary tightening cycles), the mortgage rate and monthly repayment increase. When SORA falls, the rate and repayment decrease. Borrowers benefit from rate cuts but face higher costs when rates rise.
- Spread component: The spread (e.g., +0.80% p.a.) is the bank's margin above SORA. Spreads vary by bank and loan package and are typically locked for a defined period (e.g., 2 years). After the spread lock-in period, the spread may be renegotiated at repricing.
- Lock-in periods are shorter or absent for some packages: Some SORA-pegged packages have shorter lock-in periods or no lock-in, giving borrowers more flexibility to reprice or refinance. However, packages without lock-in typically carry a higher spread.
- Transparency: SORA is a published, publicly verifiable rate set by MAS. Unlike bank board rates (which were used before SORA adoption), SORA is not at the discretion of the individual bank. Borrowers can verify the SORA rate themselves.
Key Differences at a Glance
- Certainty vs flexibility: Fixed-rate packages provide certainty of repayment for the fixed period. Floating-rate packages offer potential savings if rates fall but expose the borrower to higher costs if rates rise.
- Rate environment matters: In a rising rate environment, borrowers who locked in a fixed rate early benefit. In a falling rate environment, borrowers on floating rates benefit as their costs decline. Neither type is universally better — it depends on the direction of rates during the holding period.
- Lock-in flexibility: Floating-rate packages (especially without lock-in or with shorter lock-ins) offer more flexibility if the borrower anticipates selling the property, refinancing, or making a significant prepayment in the near term.
- Budgeting and stress tolerance: Borrowers with tighter budgets, less capacity to absorb higher payments, or strong preference for predictability often prefer fixed-rate packages. Borrowers who are comfortable with variability and want to benefit from potential rate cuts may prefer floating.
HDB Loan vs Bank Loan Rate Types
HDB concessionary loans for eligible flat owners carry a fixed rate set by HDB (pegged at 0.1% above the CPF Ordinary Account rate, which has been 2.5% for many years). HDB loan rates are effectively fixed but at HDB's discretion and can be adjusted by HDB with notice.
Bank loans for HDB flat purchases follow the same fixed vs floating structure as private property loans. Buyers choosing between an HDB loan and a bank loan must also consider the rate type as part of the overall comparison.
Guidance for Property Agents
- Frame the trade-off, not the answer: Agents should help buyers understand that neither fixed nor floating is inherently superior — the right choice depends on the buyer's financial position, rate expectations, holding period, and risk tolerance. Present it as a trade-off to discuss with a mortgage broker or bank, not a recommendation.
- Raise the rate type question early in the financing discussion: When advising buyers who are beginning to look for financing, mention that they will need to choose between fixed and floating. This prompts them to discuss the question with their bank or broker before committing to a property.
- Understand lock-in implications for sale timing: Buyers planning to sell within 2–3 years (e.g., upgraders who expect to sell before MOP expiry would not apply, but investors who may exit) face a prepayment penalty if they are in a lock-in period. Help buyers consider their likely holding period when choosing between a fixed-rate (typically longer lock-in) and floating-rate package.
- Do not advise on specific loan packages or predict interest rates: Advising on specific loan packages, comparing bank offers, or predicting where rates will go constitutes financial advice. Agents should explain the concepts and refer buyers to a licensed mortgage broker or their preferred bank for specific recommendations.
Summary
Fixed-rate home loans lock the interest rate for a defined period (typically 2–3 years), providing repayment certainty but usually carrying a premium over floating rates and a lock-in period. Floating-rate (SORA-pegged) loans move with market benchmark rates — borrowers benefit if rates fall but face higher costs if rates rise. The right choice depends on the borrower's financial position, holding period, rate expectations, and tolerance for variability. Agents should help buyers understand this trade-off, raise it early in the financing discussion, consider lock-in implications for sale timing, and refer buyers to a licensed mortgage broker or bank for specific package recommendations.
