The Thai stock market extended gains for second consecutive month in October 2025, buoyed by multiple catalysts including expectations of government stimulus measures targeting domestic consumption and tourism, better-than-expected banking sector earnings, stronger-than-estimated export figures and tourist arrivals, and upward revisions to listed companies’ net profit forecasts for 2025. Driven by these favorable conditions, the Stock Exchange of Thailand (SET) Index rose 2.8 percent from the previous month to close at 1,309.50 points at the end of October. The upward momentum gained additional support in late October as U.S.-China trade tensions eased following the APEC meeting in South Korea and the Federal Reserve (Fed) decided to trim interest rates by 25 basis points to a range of 3.75-4.00 percent in a bid to buffer against economic risks. However, analysts maintained a cautious note on long-term global economic prospects, citing uncertainties around shifting trade and monetary policies, technology-related risks and inflated AI stock valuations, and elevated public debt levels.
SET Senior Executive Vice President Soraphol Tulayasathien noted that government initiatives targeting at directly benefit citizens had delivered quick wins with measurable economic impact, effectively boosting broad-based incomes nationwide. In addition, last month’s export and tourism performance exceeded analysts’ projections, prompting upward revisions to profit estimates for Thai listed companies across various industries. Historical trading patterns also suggest that net selling by Long-Term Equity Funds (LTF) unit holders typically eases during each year’s final two months while tax-saving Thailand ESG Funds (ThaiESG) attract stronger inflows.
