Why the Straits Times Index matters today
It gives investors a simple way to gain exposure to various sectors through a single benchmark
The Straits Times Index (STI), Singapore's benchmark stock index, turns 60 this year, marking a significant milestone in the nation's corporate history. Like Singapore itself, the STI has evolved alongside the country's industrialization, financial growth, and expansion into a global business hub. Today, the STI comprises 30 of the largest and most liquid companies listed on the Singapore Exchange, reflecting the diverse sectors that have shaped the Singaporean economy.
From financial institutions like DBS, OCBC, and UOB to telecom giant Singtel and aviation leader Singapore Airlines, these companies have played a crucial role in financing businesses, connecting households, supporting travel, and enhancing the nation's infrastructure. With a recent total return of about 23 per cent in 2025, outpacing major global indices like the S&P 500 and Nasdaq Composite, the STI has garnered renewed attention from investors.
Its recent performance has also reached a milestone, crossing the 5,000 mark for the first time in February 2026. This growth has been attributed to the index's constituents, which have adapted to Singapore's evolving economy, transitioning from traditional sectors to embrace digital infrastructure, sustainability, and advanced manufacturing.
As the STI celebrates its diamond jubilee, it serves as a reminder of how Singapore's corporate champions have grown hand-in-hand with the country, and how the index continues to provide investors with exposure to both the domestic and regional growth story.
