Analysts attribute the downturn to a combination of external pressures, including rising U.S. interest rates and weaker demand from China, Thailand’s largest trading partner. “The SET is particularly sensitive to global risk appetite, and investors are pulling back amid uncertainty,” said Somchai Amornthum, chief economist at Krungthai Bank. “Domestically, concerns over fiscal stimulus delays and corporate earnings have added to the pressure.”

The Thai government has sought to reassure markets, with Finance Minister Arkhom Termpittayapaisith pledging measures to stabilize the economy. However, skepticism remains, particularly as inflation continues to outpace wage growth, squeezing household spending. Some experts argue that the market correction could present buying opportunities for long-term investors, while others warn of further declines if global conditions worsen.

Looking ahead, market participants will closely monitor upcoming central bank decisions, including the Bank of Thailand’s next interest rate meeting, for signals on monetary policy direction. With no immediate resolution to global economic headwinds, the SET’s performance in the coming weeks will hinge on both domestic policy responses and international market trends.
