Thailand’s private investment recorded a sharp upswing in September 2026, with the indicator rising to 21.6% month-over-month, according to data updated on 30 October 2026. This marks a substantial acceleration from August 2026, when private investment had grown by just 2.2% compared with the previous month.
The figures highlight a pronounced month-over-month turnaround: while August’s increase was modest, September’s data point to a strong resurgence in investment activity. Both the current (September) and previous (August) readings represent changes relative to the prior month, underscoring the scale of the latest jump in private-sector spending. Investors and policymakers will now be watching closely to see whether this momentum can be sustained in the coming months.
