The headline inflation is based on the consumer price index, which in April increased slightly from the previous month by 0.03% to 108.16. Meanwhile, core inflation in April was at 104.66, expanding 0.37% year on year.
Based on the current trend, it is estimated that inflation in May could expand by 1% to 1.5% year on year, TPSO director Poonpong Naiyanapakorn said.
Compared to other countries, Thailand is still classified as a low-inflation economy, he said. As of the end of March, Thailand’s inflation was the fifth lowest among 136 economies that announced their figures, and was the second lowest in ASEAN, said Poonpong.
The TPSO also reported that the positive inflation in April had driven up the prices of some products compared to the previous month, notably foods and non-alcoholic drinks, which have become around 0.28% more expensive.
The prices of vegetables and fruits also rose due to the impact of the hot weather that resulted in lower crop output, said Poonpong, adding that this also resulted in higher prices for dining out.
Meanwhile, food items that saw decreased prices from the previous month include pork, mackerel, vegetable oil, and garlic.
Several non-food and drink products also saw around a 0.12% price hike over the previous month in line with rising prices of petrol and gasohol, said Poonpong. They include personal-care products, toilet paper, alcoholic beverages and cigarettes.
Non-food items whose prices decreased in April included clothes, detergent and diesel fuel.
The TPSO estimated the consumer price index in May to continue to expand due to three contributing factors: higher electricity charges, rising prices of agricultural products, and the price of crude oil in the global market that could stabilise at a high level.
