Singapore: Record-Breaking STI Performance
Singapore’s benchmark stock market indicator, the Straits Times Index (STI), rose 22.67% in 2025, marking one of its strongest annual performances in over a decade. The STI broke decisively above the 4,500 mark, reaching historical highs due to broad-based strength across multiple sectors including financials, industrials, telecommunications, and real estate.

- Enhanced liquidity programs, improving market depth and bid-ask spreads.
- Encouragement of high-quality listings, attracting fast-growing regional companies.
- Global investor engagement, via roadshows and educational campaigns.
- Retail market support, making the stock market more accessible and transparent.
Sector Drivers of Growth
