Combined retail assets under management in Straits Times Index (STI) exchange-traded funds increased fivefold from $884m to $4.2b, according to the Singapore Exchange (SGX). SGX said an indicative monthly investment of $1,000 in the SPDR STI ETF from December 2019 to July 2026 would have accumulated 27,093 units from total contributions of $80,000. Based on the ETF’s July 2026 closing price of $5.751, the investment would have been valued at $155,812.

If the ETF had ended July 2026 at $3 per unit instead of $5.751, the indicative annual return would have been approximately 0.2%.
