In September 2025, Thailand experienced a 0.72% year-on-year decrease in consumer prices, a more significant decline than the anticipated 0.60% drop and following a 0.79% reduction observed in August. This trend represents the sixth consecutive month of deflation, with inflation remaining well below the central bank's target range of 1%–3%. On the other hand, core consumer prices in September increased by 0.65%, which is less than the projected 0.76% rise and a slowdown from the previous month's 0.81% increase, marking the lowest rate since August of the previous year.
