An ETF in Singapore is a basket of stocks or bonds you buy in one trade on an exchange, priced live like a share. Most ETFs are index funds wearing a different wrapper: both track a market index passively, but an ETF trades all day at SGX or overseas prices, while a traditional index fund (a unit trust here) is bought once a day at its closing value through a platform. That one structural gap decides your fees, how you buy it, and how badly the taxman dents your dividends. This guide gives you the 2026 numbers a beginner needs: what to pay, what to avoid, and the cheapest legal way to own a slice of the whole market.
People use "index fund" and "ETF" as if they fight each other. They mostly do not. An index fund is any fund that copies an index instead of trying to beat it. An ETF is one way to package that fund so it lists on an exchange. The opposite of an index fund is an actively managed fund, not an ETF.
In Singapore the practical fork is ETF versus unit trust. An ETF trades live during market hours, so you set the price with a limit order through a broker. A unit trust (including index unit trusts on platforms like Endowus or FSMOne) prices once daily at net asset value, and you buy it in dollar amounts without a stock exchange. Both can be passive. The wrapper changes the plumbing, not the underlying basket.
If you want the mechanics behind any term here, the ETF glossary entry and the index fund definition spell them out in one line each.
| Feature | ETF | Index unit trust |
|---|---|---|
| How you buy | Live order through a broker | Dollar amount through a platform |
| Pricing | Real-time during market hours | Once a day at closing NAV |
| Typical fee (TER) | 0.05%-0.60% a year | Often 0.10%-1.0% a year |
| Minimum | One board lot or fractional | From around S$50-100 |
| Best for | Lump sums, control over price | Hands-off monthly investing |
There are hundreds of ETFs but only a handful do real work for a Singapore portfolio. The job splits two ways: Singapore-dollar income, and global growth.
For local income, the two SGX-listed Straits Times Index trackers cover the 30 largest local stocks. The SPDR Straits Times Index ETF (SGX: ES3) carries a total expense ratio of 0.30% a year, and the Amova STI ETF (SGX: G3B, the fund formerly run by Nikko AM) charges 0.25%, both as of June 2026. Same index, so the cheaper one wins on cost alone.
For global growth, Singapore investors lean on Ireland-domiciled UCITS funds listed in London, bought through a global broker. The iShares Core S&P 500 UCITS ETF (CSPX) runs at a 0.07% ongoing charge. The Vanguard FTSE All-World UCITS ETF (VWRA) holds roughly 3,600 stocks across developed and emerging markets at a 0.19% ongoing charge, cut by Vanguard from 0.22%. The reason Singaporeans pick Ireland-domiciled over the cheaper US-listed versions is tax, covered next.
If you want a fund-by-fund breakdown with yields and tickers, our best ETFs in Singapore guide goes deeper than this overview.
| ETF | Ticker | Covers | Expense ratio |
|---|---|---|---|
| SPDR Straits Times Index ETF | SGX: ES3 | 30 largest SG stocks | 0.30% |
| Amova STI ETF | SGX: G3B | 30 largest SG stocks | 0.25% |
| iShares Core S&P 500 UCITS | CSPX (LSE) | 503 large US companies | 0.07% |
| Vanguard FTSE All-World UCITS | VWRA (LSE) | ~3,600 global stocks | 0.19% |
Singapore charges no tax on capital gains or on dividends you receive. The leak happens overseas, before the money reaches you. When a fund holds US stocks, the US withholds tax on the dividends those companies pay.
A US-listed S&P 500 ETF held by a Singaporean faces 30% withholding on US dividends, because Singapore has no tax treaty with the US that lowers it. An Ireland-domiciled fund holding the same US stocks pays only 15%, under the US-Ireland treaty. That 15-point gap compounds for decades, which is why CSPX and VWRA beat their cheaper US cousins on after-tax return despite a slightly higher headline fee.
There is a second reason to avoid US-listed funds for large holdings: US estate tax. A non-resident's US-situated assets above US$60,000 can be taxed at rates climbing toward 40% on death. Ireland-domiciled funds sidestep that exposure. None of this touches SGX-listed ETFs like ES3, whose Singapore dividends arrive untaxed.
The buying path depends on whether the ETF is local or overseas. For SGX-listed ETFs you can hold them in your own name through a Central Depository account, or in a broker's custody. For overseas UCITS ETFs you use a global broker that holds them under custody for you.
Local bank brokers (DBS Vickers, OCBC Securities, UOB Kay Hian) charge roughly 0.12%-0.28% with minimums around S$10-25 a trade. Global and fintech brokers (Interactive Brokers, Tiger, moomoo) run far cheaper, from about S$0.99-3 a trade plus tight FX spreads, which matters most for overseas funds. On SGX, a board lot is 100 units; at around S$3.30 a unit, ES3 starts near S$330, though regular savings plans and fractional shares lower that floor.
If a live order feels intimidating, a robo-advisor builds an ETF portfolio for you for roughly 0.2%-0.8% a year. Weigh the trade-off in our robo-advisor vs DIY ETF comparison, and if you are choosing a platform, the Endowus vs StashAway vs Syfe breakdown does the legwork.
Two government schemes let you invest with money that would otherwise sit idle, but each has fences.
Under the CPF Investment Scheme, you can buy approved SGX-listed ETFs, such as STI, bond and REIT ETFs, with Ordinary Account savings. You must keep the first S$20,000 in your OA untouched, and shares plus ETFs are capped at 35% of investible OA savings. US-listed and UCITS ETFs are not allowed under CPFIS, so CSPX and VWRA are off the table for CPF money. Your OA already earns a guaranteed 2.5%, so the bar to beat is real. The CPFIS glossary entry has the fine print.
The Supplementary Retirement Scheme is more flexible. You can buy a wide range of ETFs through SRS, and contributions cut your taxable income, up to S$15,300 a year for citizens and PRs. The catch: idle SRS cash earns about 0.05%, and withdrawing before the statutory retirement age triggers a 5% penalty plus tax. See the SRS tax-savings calculator to size the relief first.
ETFs are the right default for most people, not a free lunch. A market-cap index ETF owns the bubble as eagerly as the bargain, so you ride every drawdown in full. Buying overseas funds layers on FX spreads and conversion friction every time you add money or take dividends.
Cheap is also not free. A 0.30% fee on a S$100,000 holding is S$300 a year, which the compound interest calculator shows compounding into real money over 30 years, so chasing the lowest TER is worth the few minutes. And an ETF only diversifies within what it tracks; an STI ETF is 30 Singapore stocks heavy in banks, not a world portfolio.
The deeper choice is passive versus active, which our active vs passive investing comparison settles with the long-run data. For most Singaporeans, a low-cost index ETF held for years still wins.
Not exactly. An index fund is any fund that tracks an index instead of trying to beat it. An ETF is one way to package a fund so it lists and trades on an exchange. Most ETFs are index funds, but an index fund can also be a unit trust that prices once a day rather than trading live.
For overseas UCITS ETFs, a low-cost global broker such as Interactive Brokers, Tiger or moomoo keeps commissions near S$1 a trade with tight FX spreads. For SGX-listed ETFs like the STI ETF, fintech brokers and regular savings plans cost far less than the local bank brokerages, whose minimums of S$10-25 hurt small trades.
Ireland-domiciled UCITS funds pay 15% US dividend withholding tax under the US-Ireland treaty, half the 30% a Singaporean pays on US-listed funds. They also avoid US estate tax, which can hit US-situated assets above US$60,000. Over decades that tax saving outweighs the slightly higher expense ratio.
Yes, with limits. CPF Ordinary Account money can buy approved SGX-listed ETFs only (not US or UCITS funds), after keeping S$20,000 in your OA and within a 35% shares-and-ETF cap. SRS is more flexible and gives income-tax relief up to S$15,300 a year, but early withdrawals carry a 5% penalty plus tax.
