Thailand’s economy expanded by 0.70% quarter-over-quarter in the first quarter of 2026, marking a notable slowdown from the 1.90% growth recorded in the fourth quarter of 2025. The latest data, updated on 18 May 2026, underline a weakening short-term growth momentum compared with the previous quarter.
On a quarter-over-quarter basis, the current reading captures how output in the first quarter of 2026 compares to the final quarter of 2025, while the earlier 1.90% figure reflected growth in Q4 2025 relative to Q3 2025. The deceleration suggests that economic activity cooled at the start of 2026, although the economy continued to expand rather than contract.
The shift from 1.90% to 0.70% quarter-over-quarter growth will be closely watched by investors and policymakers as they assess the durability of Thailand’s recovery path and the potential need for policy adjustments if the softer growth trend persists into subsequent quarters.
