Amid efforts to restore confidence in Thailand's capital market the Stock Exchange of Thailand (SET) has issued clarifications on three key issues attracting investor attention, namely
These three issues reflect challenges facing the Thai capital market, including the volatility of large-cap stocks affecting the overall market, handling information that may impact investor decisions, and raising regulatory standards to prevent risks and maintain market credibility.
SET executives have explained their approaches and perspectives on each issue as follows:
Regarding the volatile movements of DELTA shares impacting the overall SET Index, Assadej Kongsiri, Director and Managing Director of the SET, stated that, in practice, the SET cannot apply criteria targeting any individual or company specifically and prefers to let market mechanisms operate and drive the market.
However, if unusual trading patterns or price movements lack clear fundamental support are detected, the SET will step in to issue warnings and advise investors to analyze information before making trading decisions.
Moreover, the SET acknowledges that DELTA significantly affects the SET Index and has worked to improve the SET50 and SET100 indices by adopting a capped weight approach to better reflect market conditions.
Meanwhile, the overall SET Index remains a composite index calculated at 100% weight per international standards.
Nonetheless, investors are strongly urged to thoroughly study the business details of companies before investing.
Rumors about JAS acquiring World Cup broadcast rights remain closely watched by investors, as no official announcement has been made by the listed company amid speculative price movements.
Assadej explained that the SET continuously monitors related developments and coordinates with listed companies to watch for information that might influence investor decisions.
However, when news lacks clarity or verifiable references, the SET must exercise caution in ordering companies to disclose information to avoid directing investors toward any particular conclusion.
Although not requiring immediate public clarification, the SET generally maintains ongoing discussions with listed companies to closely track situations when concerns arise.
Regarding the Securities and Exchange Commission (SEC) charging Finansia Syrus Securities Public Company Limited to the Economic Crime Suppression Division for insufficient customer identification and due diligence (KYC/CDD), including failure to conduct enhanced KYC/CDD for suspicious transactions, violating Section 113,
Assadej noted that the SET is aware of the SEC's announcement and is closely following the matter, although direct talks with the broker have not yet occurred. He acknowledged concerns in recent months questioning whether the Thai capital market is a money laundering venue. Hence, frontline systems like KYC/CDD are crucial for preventing improper funds and behaviors from entering the market.
To maintain market confidence, the SET will enforce and engage with member companies and brokers to enhance rigor in these processes moving forward.
Meanwhile, Dr. Saraphol Tulayasathien, Deputy Managing Director and Head of Corporate Strategy and Finance at the Stock Exchange of Thailand (SET), revealed that investor confidence issues arising from securities companies’ problems or corporate governance matters present an opportunity to improve procedures and review regulations to strengthen the system and build trust among investors.
Dr. Saraphol reported that the Thai stock market performed well in May, with the index rising about 5%, and since the start of 2026, it has increased roughly 25%, ranking third globally after Taiwan and South Korea.
Key drivers included easing Middle East war concerns, stronger-than-expected Q1 2026 GDP figures, clearer government policies supporting the economy and purchasing power, and solid corporate earnings.
Additionally, average daily trading value remained robust at around 63 billion baht, with foreign fund inflows exceeding 20 billion baht after outflows in April due to war concerns.
Looking ahead to June, Dr. Saraphol noted that previously eased concerns have resurfaced, including ongoing war conflicts and inflation worries.
Recently, strong U.S. employment numbers led markets to expect the Federal Reserve to shift focus from recession fears to inflation control, raising the possibility of interest rate hikes this year if inflation remains high.
These concerns pressured technology and AI stocks with long-term revenue projections, evident in the NASDAQ index dropping about 5%, along with declines in Korean and Taiwanese markets.
Investors are advised to be cautious, diversify risks, and closely monitor information. Nonetheless, while global markets fluctuate, the Thai stock market has been relatively shielded.
Moreover, foreign investors increasingly view Thai stocks as a “safe haven,” especially high-dividend and traditional economy stocks, supported by economic stability strengths.
