A report published by reports on 16 September 2026 projects that Southeast Asia’s six largest economies will expand at an average rate of 4.8 per cent a year between 2026 and 2035.
The report identifies Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam as the six economies underpinning the regional figure and sets the timeframe for the projection as 2026–2035.
Growth drivers
According to the publication, the projected expansion will be supported by sustained foreign investment and capital formation, continued industrialisation and infrastructure development, and productivity.
The report was released on a Wednesday and frames the 4.8 per cent average as a medium-term outlook for the group of economies rather than an estimate for any single year.
Regional implications
The projection covers a decade-long interval and presents a composite growth rate for the six economies rather than separate forecasts for each country named by the report.
Sources published the item under the heading Report: SE Asia economies set for 4.8% growth annually through 2035, noting the principal drivers that it says will sustain the aggregate expansion over the period cited.
