Thailand’s SET Index closed at 1,576.25 points, decreased 27.88 points or 1.74%, with a trading value of THB 97.96 billion. The analyst stated that the Thai market plunged as investors sold off equities to mitigate risks after the Middle East situation re-escalated. This followed the Iranian attacks on ships in the Strait of Hormuz, and President Donald Trump declared the end of the U.S.-Iran ceasefire.
Furthermore, oil prices rose following the renewed tension, which is a negative factor for stock markets.
For tomorrow, the analyst expects the Thai market to move sideways, recommending investors closely monitor the situation in the Middle East.
The U.S. military initiated a campaign of powerful strikes against Iranian targets. The action was taken in response to incidents on Tuesday, when three commercial vessels traveling through the Strait of Hormuz were assaulted.
Furthermore, the U.S. Treasury Department removed a waiver that previously permitted Iranian oil exports, signaling a shift to a stricter policy amid rising tensions.
President Trump announced that the memorandum of understanding with Iran aimed at solving the conflict had ended, stating that he does not wish to pursue engagement with Tehran. Trump indicated that although U.S. officials might continue negotiations, he doubted they would achieve any results, signaling he personally considered the ceasefire efforts concluded.
South Korea’s Kospi index fell sharply into bear market territory, dropping 20% from its record high set earlier this year. Persistent losses in leading technology shares have fueled investor caution and underscored mounting volatility, making Kospi the world’s most turbulent major market in 2026.
