Bangkok: Thai inflation in November 2015 was negative at 0.49%, marking the eighth consecutive month of negative growth.
According to Thai News Agency, this decline was attributed to falling energy prices and government cost-of-living measures, although there were rising prices for fresh vegetables and prepared foods. The Ministry of Commerce projects the general inflation rate for 2016 to be between 0.0 and 1.0%.
Mr. Nantapong Jiralertphong, Director of the Office of Trade Policy and Strategy and spokesperson for the Ministry of Commerce, revealed that Thailand's general consumer price index in November 2025 was 100.15, a decrease from 100.64 in November 2024. This resulted in a 0.49% year-on-year decrease in headline inflation, a slower rate compared to the same period last year. The decline was primarily due to a 0.76% decrease in October 2025. The main reason for the continued decline in headline inflation was the price of energy products, including household electricity and fuel, which decreased in line with the global energy situation and government measures to reduce the cost of living. Meanwhile, food and non-alcoholic beverages saw an increase after three consecutive months of decline, driven by higher prices of fresh vegetables, prepared foods, and non-alcoholic beverages. Prices of other goods and services had a minimal impact on inflation.
Regarding Thailand's general inflation rate compared to other countries, the latest data for October 2025 found that Thailand's general inflation rate decreased by 0.76 percent year-on-year, ranking third among the 132 economies that announced figures and the lowest among the nine ASEAN countries that announced figures, including Brunei, Timor-Leste, Singapore, Malaysia, the Philippines, Indonesia, Vietnam, and Lao PDR.
The general inflation rate decreased by 0.49 percent year-on-year in November 2015, driven by a 1.13 percent year-on-year decrease in non-food and beverage categories, particularly electricity, gasohol, diesel, and gasoline. Non-alcoholic food and beverage categories increased by 0.54 percent year-on-year, including coriander, morning glory, and instant coffee. However, prices of many products decreased, including fresh fruit, chicken eggs, glutinous rice, white rice, pork, and garlic.
Core inflation, excluding fresh food and energy, rose 0.66 percent year-on-year, accelerating slightly from October 2015, which rose 0.61 percent year-on-year.
The Consumer Price Index for November 2025 increased by 0.15 percent month-on-month compared to October 2025, following an increase in the food and non-alcoholic beverage category by 0.28 percent month-on-month and other non-food and beverage categories by 0.06 percent month-on-month. The average Consumer Price Index for the first eleven months of 2025 compared to the same period in 2024 decreased by 0.12 percent annually.
The Ministry of Commerce forecasts that the headline inflation rate in 2026 will be between 0.0 and 1.0 percent, with a median of 0.5 percent. Factors contributing to this upward trend include improvements in agricultural prices due to the policy of stabilizing the prices of key agricultural products, a reduction in the cultivation of low-priced products, and an improving tourism sector. Conversely, factors contributing to the downward trend in headline inflation include declining global crude oil prices, government measures to reduce the cost of living, and a slow expansion of the Thai economy at 1.7 percent in 2026. Additionally, there is a tendency to import low inflation from abroad due to low-level expansions in important economies, leading to decreased production and export prices, coupled with the strong baht causing Thailand to import low-priced goods.
