KKP Research upgraded Thailand's 2026 GDP forecast to 2.5% (from 2.1%), driven by AI investment and strong tourism, but warns of widening K-Shape divergence: emerging AI/electronics sectors boom while traditional industries (automotive, petrochemicals) and SMEs struggle.

Policymakers should monitor the 400-billion-baht fiscal stimulus and US trade negotiations.
