On 30 Sep 2026, the SET index closed at 1,559.01 points, down 35.29 points (−2.21%), on selling in large-cap banking and telecom stocks. Foreign investors cut positions after the Thai market had run harder than its regional neighbors.
Why it moves markets, and what history says
High bond yields and the possibility that the Fed will raise interest rates again are driving foreign capital out of emerging markets, so large-cap stocks with heavy foreign ownership were sold first.

In a rising-rate cycle the dollar is usually the winner, while assets that rely on cheap money (growth stocks, crypto) tend to struggle. When the Fed keeps signalling tightening, be careful trading against the dollar trend. See details

Deeper view and what to watch
The 1,600-point level has become short-term resistance. Analysts see a chance of a short-term rebound, but as long as foreign investors remain net sellers and the baht stays weak, a rebound tends to be limited. Watch the daily net foreign buy/sell figures and the outcome of the Fed meeting in late Oct.
