Thailand Inflation Climbs to Over 3-Year High

Thailand’s annual inflation rate surged to 3.9% in October 2026 from 2.82% in September, exceeding market expectations of 3.33% and breaching the Bank of Thailand’s 1%-3% target range for the first time in more than three years. The reading marked the highest level since January 2023. The acceleration was driven largely by higher oil prices and flood-related increases in food costs, reflecting elevated raw material costs and the impact of the conflict in the Middle East. Meanwhile, annual core inflation rose to 1.58% from 1.50% in September, remaining its highest level since May 2023 but remaining slightly below market forecasts of 1.6%. The Commerce Ministry expects headline inflation to average 1.8%-2.2% in 2026, although price pressures may remain elevated through year-end partly due to a low base effect. Despite the breach, officials expect the increase to be temporary, while the Bank of Thailand has maintained its policy rate at 1% amid subdued domestic demand.

Thailand’s annual inflation rate rose to 2.82% in September 2026 from 2.53% in August, but came in below market expectations of 3.10%. The reading marked the highest level since April, bringing inflation closer to the upper end of the Bank of Thailand’s 1%-3% target range. The acceleration was driven largely by higher oil and processed food prices, reflecting elevated raw material costs and the impact of the conflict in the Middle East. Meanwhile, annual core inflation rose to 1.50% from 1.44% in August, reaching its highest level since May 2023 but remaining slightly below market forecasts of 1.54%. Headline inflation is expected to accelerate further in the fourth quarter, with October’s rate projected to rise from September’s level, Trade Policy and Strategy Office chief Nantapong Chiralerspong said. He added that recent flooding is expected to have only a limited impact on inflation. The Commerce Ministry expects headline inflation to average 1.80%-2.20% this year.

Thailand’s annual inflation rate accelerated for the first time in four months to 2.53% in August 2026, from 1.95% in July, surpassing market expectations of 2.2%. It was the fastest increase since May, boosted by higher domestic fuel prices amid rising oil prices due to the ongoing conflict in the Middle East. However, the latest reading remained within the Bank of Thailand’s 1%-3% target range. Non-food inflation rose by 2.23%, while food and non-alcoholic beverages inflation increased by 2.99%. Meanwhile, the annual core inflation rate, which excludes volatile energy and fresh food prices, accelerated to 1.44% in August 2026 from 1.34% in July, marking the highest reading since May 2023 and exceeding forecasts of 1.33%. Thailand's Ministry of Commerce maintained its 2026 headline inflation forecast at 1.5%-2.5%, with a 2.0% midpoint. On a monthly basis, consumer prices rose 0.56%, rebounding from a 0.73% decline in July and marking the fastest increase in four months.
