Krungsri Securities said the Thai stock market between 21 and 24 September 2026 moved above the 1,600-point level, supported by positive expectations that the US leader will meet the Chinese leader on 24-25 September, which boosts the prospect of further trade easing.

The refinery and petrochemical group, such as TOP, SPRC and PTTGC, rose on news that the US is preparing to ban or halt diesel exports, which if implemented would tighten diesel supply in the market and push refining margins higher.
