FX.co ★ Thailand’s Core Inflation Edges Up in September, Hinting at Gradual Price Pressures

Thailand’s core Consumer Price Index (CPI) ticked higher in September 2026, suggesting a modest buildup in underlying price pressures in the economy.

Core CPI, measured on a year-over-year basis, rose to 1.50% in September from 1.44% in August 2026. Both figures compare prices in each respective month with the same month a year earlier. The September reading, updated on 06 October 2026, indicates that core inflation continues to move gradually higher, though it remains at a relatively contained level.

For policymakers and markets, the uptick underscores a slow but continuing firming in underlying inflation dynamics, which could factor into expectations for future monetary policy decisions if the trend persists in the coming months.
