The Thai stock market has transitioned from rangebound behavior to facing increased downward pressure and volatility. While the SET Index was previously expected to trade sideways between 1,600 and 1,640 points—supported by high crude oil prices benefiting the energy and petrochemical sectors—recent shifts in global financial conditions have intensified market instability.

A significant driver of this volatility is the surge in U.S. bond yields, with the 10-year Treasury yield reaching a 20-month high of approximately 4.7% to 4.8%. This trend is pressuring risk assets and prompting investors to pivot toward commodities and defensive stocks. Market participants are also closely monitoring U.S. economic data and employment reports to gauge Federal Reserve policy, with a 67% market probability of a rate hike in September following hawkish signals.

Geopolitical tensions continue to influence the market, specifically regarding the Middle East and missile testing by Russia. Domestically, the market is navigating political uncertainty alongside international trade tensions, including U.S. tariffs and sanctions. While events like ‘Thailand Focus 2026’ were expected to provide support, the combination of rising yields and global instability has led experts to recommend caution and a focus on defensive growth and recovery stocks.
