Thailand’s SET Index Edges Lower as Southern Floods Dampen Economy

Mr. Vathan Jitsomnuk, Director of Strategy Analysis at Pi Securities, stated that the Stock Exchange of Thailand (SET) Index decreased by 0.15% or 1.96 points to 1,266.82 points this morning, moving against most regional markets.

Most markets extended gains on expectations that the U.S. Federal Reserve (Fed) may reduce interest rates in December after recent economic data showed signs of slowing. As for the Thai market, this factor has not provided significant support as it remains under pressure from concerns over the growth outlook for the Thai economy.

Previously, it was expected that the overall economy and tourism sector would recover in the fourth quarter of 2025 during the high season. Yet, the flooding situation in the southern region has become a negative sentiment.

Although the impact on listed companies with operations or branches in the affected area is limited, it still poses a risk to economic growth and may lead to downward revisions to forecasts, particularly as southern tourism is affected and recovery will take time.

For this afternoon, the index is expected to continue its decline with thin trading volume. The support level is set at 1,258 points, with resistance at 1,280 points.
