SET Index closed out a solid first half of 2026 at 1,591.24 points, gaining 1.5 percent from the previous month and 26.3 percent from the end of 2025. Easing tensions in the Middle East, following progress on the peace deal, bolstered investor sentiment. However, sporadic clashes still flaring up signal that the truce remains fragile - alongside the U.S. Federal Reserve (Fed)’s monetary policy maneuvers, another factor markets are watching closely. Global equities, meanwhile, saw heightened volatility amid AI bubble concerns, triggering corrections across major bourses worldwide. Thai equities, however, weathered the storm relatively well, buoyed by solid domestic fundamentals across several fronts.
Exchange of Thailand (SET) Executive Vice President and Head of Research Department Chatchai Thisadoldilok stated that domestic factors supporting the Thai stock market in June 2026 included the Bank of Thailand (BOT)’s upward revision of its 2026 GDP growth forecast to 2.3 percent from 2 percent previously, driven mainly by robust export growth, a limited impact from the Middle East conflict, and government economic stimulus measures. Meanwhile, leading global credit rating agencies Moody's Ratings and S&P Global Ratings have assigned Thailand's sovereign credit rating at a Stable Outlook. Analysts have also raised earnings forecasts for several business sectors in the Thai stock market. Foreign investors were net buyers of over USD 211 million in June, bringing first half net purchases to a total of USD 881 million.
