CPF Ordinary Account Investment Returns Singapore 2026
The CPF Ordinary Account (OA) earns a guaranteed interest rate of 2.5% per annum (with an additional 1% on the first S$20,000 for CPF members below age 55, and additional interest for older members). For many Singapore investors, the key question is whether to keep funds in the OA at this guaranteed rate, or invest via the CPF Investment Scheme (CPFIS-OA) in higher-returning but riskier assets such as ETFs, unit trusts, bonds, or shares.
Understanding what CPF OA investment returns actually look like in practice — and how they compare to the guaranteed 2.5% floor — is essential for making an informed decision about your CPF strategy in 2026.
The CPF OA Guaranteed Rate: A High Bar to Beat
The 2.5% p.a. OA rate is fully guaranteed by the Singapore government, with zero volatility and zero capital risk. This is not a trivial hurdle — comparable risk-free returns (e.g., Singapore Savings Bonds or T-bills) have fluctuated significantly, and in low-rate environments (2015–2021), the CPF OA’s 2.5% was actually higher than many comparable instruments.
For CPFIS-OA investments to be worthwhile, they must consistently beat 2.5% after accounting for fees, taxes, and the cost of staying out of the guaranteed return. Research by MAS and CPF Board has historically shown that a majority of CPFIS investors underperform the OA’s guaranteed rate, often due to poor fund selection, high expense ratios, or poorly timed entries/exits.
CPFIS-OA Investment Options
Approved CPFIS-OA investments include unit trusts/mutual funds, ETFs listed on SGX, Singapore government bonds and T-bills, corporate bonds, endowment insurance policies, investment-linked insurance products (ILPs), and shares listed on SGX. Notably, CPFIS-OA cannot be used to invest in overseas stocks directly (only via approved unit trusts or ETFs), and certain high-risk instruments are excluded.
The most cost-effective CPFIS-OA investment for retail investors is typically a low-cost broad market ETF — for example, the LION-OCBC Securities Hang Seng TECH ETF or STI ETF via FSMOne at zero commission. See our guide on CPFIS in Singapore for the full list of approved products.
Historical Performance: CPFIS vs. OA Rate
CPF Board publishes an annual analysis of CPFIS-OA investor returns. Consistent findings across multiple years:
- In bull market years (e.g., 2019, 2021), the majority of CPFIS-OA investors outperformed the 2.5% benchmark, driven largely by equity market gains.
- In volatile or bear market years (e.g., 2018, 2022), many CPFIS-OA investors underperformed, with some losing capital in absolute terms.
- Long-term analysis (10+ years): Investors in diversified low-cost index ETFs generally outperformed 2.5% over full market cycles, but with significant year-to-year volatility. Actively managed unit trusts with high expense ratios fared poorly on a net-of-fee basis.
The 35% Cash Residual Rule
Under CPFIS-OA rules, you must maintain at least S$20,000 in your OA before investing (or keep 35% of investable savings in cash/fixed deposits). This ensures you retain some OA liquidity for housing needs or retirement. When calculating potential CPFIS-OA investments, factor in this reserve requirement.
When It May Make Sense to Invest OA
Investing your CPF OA via CPFIS may make sense if: you have a long investment horizon (10+ years), you select low-cost, diversified instruments (expense ratio < 0.5%), you can tolerate short-term volatility, and you do not need the OA balance for housing in the near term. Conversely, if you're within 5–10 years of retirement or actively using your OA for housing, the guaranteed 2.5% is a strong argument for keeping funds invested there. For retirement income planning, also explore CPF retirement drawdown strategies.
