The CPF Board has confirmed that interest rates for Q3 2026 (1 July to 30 September 2026) remain unchanged across all four CPF account types. The Ordinary Account (OA) stays at 2.5% per annum, while the Special, MediSave, and Retirement Accounts (SMRA) hold steady at 4% per annum — rates that, with bonus interest, can effectively reach 3.5% and 5% respectively for eligible members.

CPF Interest Rates Q3 2026: The Full Picture
For the third quarter of 2026, Singapore’s Central Provident Fund (CPF) Board has kept interest rates stable, in line with the Government’s commitment to protect members’ retirement savings in a lower-yield environment. Both the OA pegged rate and the SMRA pegged rate remain below their respective floor rates, meaning the floors continue to apply.
Here is the complete breakdown of all CPF interest rates effective 1 July to 30 September 2026:
| CPF Account | Base Rate (p.a.) | Effective Rate with Bonus* (p.a.) | Rate Type |
|---|---|---|---|
| Ordinary Account (OA) | 2.5% | Up to 3.5% | Floor Rate |
| Special Account (SA) | 4.0% | Up to 5.0% | Floor Rate |
| MediSave Account (MA) | 4.0% | Up to 5.0% | Floor Rate |
| Retirement Account (RA) | 4.0% | Up to 5.0% | Floor Rate |
| HDB Concessionary Loan | 2.6% | — | OA + 0.1% |
*Bonus: extra 1% on first $60,000 combined CPF for members below 55 (capped at $20,000 for OA). Members 55+: extra 2% on first $30,000 and extra 1% on next $30,000.
Why Have CPF Rates Stayed Unchanged?
The stability in CPF interest rates is by design. Both the OA and SMRA rates are formula-driven, pegged to market benchmarks, but protected by government-set floors.
The OA rate is computed as a three-month average of major local banks’ interest rates (80% fixed deposit rates + 20% savings rates). With Singapore bank savings rates well below 2.5%, the OA floor continues to shield members from low market yields.
The SMRA rate is pegged to the 12-month average yield of 10-year Singapore Government Securities (10YSGS) plus 1%. With 10-year SGS yields currently below 3%, the SMRA pegged rate falls below the 4% floor — so members enjoy the protected 4% return.
The floor mechanism ensures you are never penalised by falling market interest rates. CPF savings compound at stable, guaranteed rates regardless of what happens in financial markets.

Bonus Interest: The Real Yield for Most Singaporeans
The headline rates of 2.5% (OA) and 4% (SMRA) tell only part of the story. The Government pays additional bonus interest to boost retirement savings — and for most working Singaporeans, the effective yield is meaningfully higher.
Members below age 55:
- Extra 1% interest on the first $60,000 of combined CPF balances (capped at $20,000 for OA)
- OA effectively earns 3.5% on the first $20,000; SA/MA effectively earn 5% on the first $60,000 combined
Members aged 55 and above:
- Extra 2% interest on the first $30,000 of combined CPF balances (capped at $20,000 for OA)
- Extra 1% interest on the next $30,000 of combined CPF balances
- Effective SA/RA yields can reach 6% for the first $30,000 tier
Important nuance: extra interest earned on OA balances goes into your Special Account (or Retirement Account if 55+) — not back into OA. This directs the bonus towards retirement savings.

The 4% SMRA Floor: Guaranteed Until 31 December 2026
One of the most important CPF developments this year is the Government’s extension of the 4% floor rate for SA, MA, and RA monies until 31 December 2026. Without this floor, the formula-based SMRA rate would fall below 4% due to current SGS yields.
The difference is material: a member with $200,000 in their Retirement Account earns $8,000 per year at 4% — versus roughly $5,600 at a formula rate of approximately 2.8% without the floor. The extension is worth approximately $2,400 per year per $200,000 of SMRA balance.
If you are deciding whether to top up your SA or invest, our CPF Top-Up vs Investing Calculator models both scenarios with current rates.
CPF vs Alternatives: How Competitive Is 4%?
In context against other Singapore savings vehicles as of September 2026:
- Bank savings accounts: Most offer 0.05% to ~2% base rates. High-yield accounts require meeting salary credit, card spend, and product conditions. See our UOB Fixed Deposit guide and OCBC Fixed Deposit comparison.
- Fixed deposits: Singapore bank FD rates range from 1.25% to 2.95% p.a. for SGD, with best rates requiring $50,000+ minimums and lock-in periods.
- Singapore T-Bills (6-month): Cut-off yields have moderated to approximately 2.8 to 3.1% in recent auctions, down from 2023 to 2024 peaks.
- CPF SA/RA at 4% (or 5% with bonus): Fully guaranteed, no action required, no reinvestment risk. Beats every listed alternative — but funds are locked until retirement.
HDB Concessionary Loan Rate — Q3 2026
The HDB concessionary loan interest rate remains at 2.6% per annum for Q3 2026, pegged at 0.1% above the CPF OA floor of 2.5%. For existing HDB borrowers, there is no change to their monthly repayment quantum.
The opportunity cost of using OA for housing is just 0.1% — OA earns 2.5% while the HDB loan charges 2.6%. This minimal spread means continuing to service your HDB loan via CPF OA remains financially sensible for most homeowners.
Action Steps for Singapore Investors — September 2026
- Maximise SA/MA bonus interest: If your combined CPF balance is below $60,000, every dollar in SA or MA earns an effective 5% — one of the best risk-free rates in Singapore.
- Consider a voluntary SA top-up before year-end: The 4% floor is confirmed only to 31 December 2026. Top-ups to SA also qualify for CPF Cash Top-Up Relief of up to $8,000 per year in income tax relief.
- Do not over-optimise OA-to-SA transfers: OA-to-SA transfers are irreversible. Preserve OA liquidity if you anticipate needing funds for housing, education, or CPFIS investments.
- Review MediSave utilisation: MediSave earns 4% — same as SA. If approaching the Basic Healthcare Sum cap of $79,000, excess flows automatically to SA/RA. Read our complete MediSave guide.
Bottom Line for SG Investors
CPF interest rates for Q3 2026 are stable: OA at 2.5%, SA/MA/RA at 4%, HDB loan at 2.6%. With bonus interest, effective yields reach 3.5% (OA) and 5% (SA/MA) for members below 55 on the first $60,000 of combined balances. The Government’s 4% SMRA floor is guaranteed through 31 December 2026.
Against Singapore bank FD rates of 1.25 to 2.95% and T-Bill yields of approximately 2.8 to 3.1%, CPF SA/RA offers the highest guaranteed yield available to retail Singapore investors — with zero credit risk and government backing. The tradeoff is illiquidity: these funds are earmarked for retirement.
For most working Singaporeans, the smart approach is to treat CPF SA/RA as the high-yield safe bucket in a broader portfolio — let it compound at guaranteed rates, and direct discretionary capital toward growth assets for market upside.
Frequently Asked Questions
What are the CPF interest rates for Q3 2026?
CPF interest rates for Q3 2026 (1 July to 30 September 2026): Ordinary Account (OA) — 2.5% p.a.; Special Account (SA), MediSave Account (MA), and Retirement Account (RA) — 4.0% p.a. HDB concessionary loan rate — 2.6% p.a. All confirmed by the CPF Board as floor rates.
Why are CPF interest rates unchanged for Q3 2026?
Both the OA and SMRA pegged rates remain below their respective floor rates of 2.5% and 4%. The OA pegged rate (based on major local bank rates) and the SMRA pegged rate (based on 10-year SGS yield plus 1%) both fall below the floors given current market conditions, so the floors apply and rates stay unchanged.
How long is the CPF 4% interest rate floor guaranteed?
The Government has extended the 4% floor for Special, MediSave, and Retirement Account monies until 31 December 2026. Beyond that, there is no guarantee — the decision is made periodically. The floor has been renewed consistently since its introduction.
What is the effective CPF interest rate with bonus interest?
For members below 55: OA earns an effective 3.5% on the first $20,000 of OA balances; SA/MA earn an effective 5% on the first $60,000 of combined CPF balances. For members aged 55 and above, effective rates on SA/RA can reach 6% for the first $30,000 tier (base 4% plus extra 2% bonus).
Is CPF SA better than Singapore fixed deposits in 2026?
