Thailand’s private investment turned sharply negative in March 2026, falling by 3.5% month-over-month, according to data updated on 30 April 2026. The decline marks a notable reversal from February 2026, when private investment had grown by 1.9% compared with January.
The latest figures show that the momentum seen earlier in the year has stalled, with March’s contraction erasing February’s gains on a month-to-month basis. The data are based on a month-over-month comparison, where the current reading measures the change in March versus February, and the previous figure reflects the change in February versus January.
