Three Singapore equity ETFs track the STI index and trade on SGX: Nikko AM STI ETF (ES3), SPDR STI ETF (SPYY), and smaller alternatives. The STI ETF share price fluctuates based on the underlying Straits Times Index — comprised of 30 large-cap Singapore companies like DBS, Singtel, and CapLand Ascott Trust. Nikko AM’s ES3 is the most popular, with the lowest expense ratio (0.32%) and highest trading volume. If you own Singapore’s blue chips via an ETF, tracking the daily price helps you monitor your portfolio’s real-time value and catch dividend distributions.

- Track prices via SGX, Nikko AM’s website, or your broker’s app
- Dividend yields range from 3.2–3.5% annually across all three ETFs
1. What Is an STI ETF? (Why You Should Care)
An STI ETF is a fund that tracks Singapore’s top 30 blue-chip companies — the Straits Times Index. Instead of buying all 30 stocks individually (expensive and time-consuming), you buy one ETF unit that gives you exposure to the entire index.
The three main STI ETFs listed on SGX are:
- Nikko AM STI ETF (ES3) — most popular, 0.32% TER
- SPDR STI ETF (SPYY) — lower fees at 0.30%, less liquidity
- AMOVA STI ETF (AYST) — smallest, rarely traded
Why track the STI ETF price? The share price tells you the current market value of your holding. When the STI index rises, the ETF price rises — and vice versa. Tracking price is how you monitor your portfolio on any given day.
