Thailand's Q2 2026 GDP growth slowed to 1.9% YoY from 2.8% in Q1, making it the weakest performer in ASEAN—trailing Vietnam (8.4%), Malaysia (6.0%), Singapore (5.9%), Indonesia (5.3%), and Philippines (2.3%). Weakness stemmed from declining private consumption, reduced government spending, contracting public investment, and broad production slowdowns. However, the National Economic and Social Development Council revised full-year 2026 growth forecast upward to 2.0–2.5% (midpoint 2.2%), citing recovery in exports, tourism, and private investment.
