The main reason behind the high CPI rise was that energy prices in Thailand remained high.
The country’s headline inflation rate in August rose slightly from the previous month to a 14-year high, in line with forecast and reinforcing expectations of a further interest rate hike later this month.
The pace, the fastest since July 2008, was far above the central bank's target range of 1% to 3%.
Ronnarong Phoolpipat, an official of the ministry said the inflation rate may have peaked in August, citing that inflation stayed at 7% levels for three months in a row, suggesting it has peaked and will come down if the price situation continues to stay at current levels.
The ministry expects inflation at around 5% in the fourth quarter and a range of 5.5% to 6.5% in the whole of 2022, he said.
In August, the core CPI index, which does not include energy and fresh food prices, rose 3.15% from a year earlier, lower than a forecast 3.20%, but faster than July's 2.99%.
In the January-August period, headline inflation of the Southeast Asian nation was 6.14% and the core rate was 2.16%./.
