Singapore Stock Market Today: STI Jumps 1.5% to 4,586 as Banks Rally; Sembcorp-Alinta Deal and Seatrium Contract in Focus (Dec 12, 2025)
SINGAPORE (Dec 12, 2025) — The Singapore stock market ended the week on a strong note on Friday, with the Straits Times Index (STI) climbing 1.5% (up 65.62 points) to 4,586.45. Market breadth was firmly positive, as gainers outpaced losers 360 to 200, with 1.3 billion securities changing hands for roughly S$1.7 billion in turnover. The Business Times Today’s upswing came as Asian equities broadly advanced, even while global investors continued to debate the “next leg” of the rally after renewed volatility in big tech — a theme reignited by Oracle’s weak forecast and heavier AI-related spending plans.
