SET Index Slides as Investors Monitor Prime Ministerial Vote and Global Developments

Mr. Natapon Khamthakrue, Assistant Managing Director of Securities Analysis at Yuanta Securities (Thailand), stated that the SET Index closed this morning at 1,436.74 points, down 4.11 points (-0.29%), with a trading value of THB 38.56 billion. The market traded relatively flat as investors awaited the results of the prime ministerial vote, which, based on historical data, typically sees the index rise on voting days.

However, the decline was attributed to external factors, including a rise in crude oil prices due to the ongoing conflict in the Middle East and an increase in U.S. government bond yields after the Federal Reserve signaled an upward revision in its 2026 inflation forecast, even before factoring in the potential impact of situations in the Middle East.

As a result, stocks sensitive to higher oil prices and bond yields dragged the market down this morning. Meanwhile, the Thai baht also weakened, and foreign investors continued to sell Thai equities.

Mr. Natapon believes that the downside for the Thai stock market is relatively limited compared to the region, due to speculation surrounding the formation of a new government. For this afternoon, the index is expected to remain stable amid potential pressure for tomorrow from the FTSE index revision.

The analyst sets the support level at 1,425 points and the resistance level at 1,440 points.
