In December 2025, consumer prices in Thailand experienced a modest decline of 0.28% compared to the same period a year earlier. This reduction was slightly less than the anticipated 0.40% drop and marked an improvement from the 0.49% decrease recorded in November. Notably, this represented the ninth consecutive month of declining prices, with inflation remaining significantly below the central bank's target range of 1% to 3%. In contrast, core consumer prices, which exclude volatile categories such as food and energy, continued to exhibit a positive trend. These prices rose by 0.59% on an annual basis, falling short of the projected 0.69% increase and down from November's 0.66% rise.
