Thai Stock Market Outlook: Investors Await GDP Revision
Pi Securities forecasts the SET index to trade between 1,590 and 1,620 points today, with market attention focused on upcoming GDP data.
According to a report by Prachachat Business on August 17, 2026, Pi Securities has projected that the Stock Exchange of Thailand (SET) index will fluctuate within a range of 1,590 to 1,620 points. Market sentiment is currently influenced by a slight gain of 0.5% in the Japanese stock market, which analysts view as a positive psychological factor for regional trading.
The primary focus for investors today is the upcoming announcement from the Office of the National Economic and Social Development Council (NESDC) regarding potential revisions to Thailand's Gross Domestic Product (GDP) figures. These adjustments are critical as they provide a clearer picture of the nation's economic health and growth trajectory.
For residents and expatriates, fluctuations in the SET index often reflect broader economic confidence. While stock market movements do not directly impact daily living costs, significant shifts in GDP projections can influence future economic policy, currency stability, and the overall business environment in Thailand. At this stage, the market remains in a wait-and-see mode. Observers are waiting for the official NESDC release to confirm whether the economic outlook will be adjusted upward or downward, which will likely dictate the market's direction in the coming sessions.
