Paris: Annual consumer inflation in the Organization for Economic Cooperation and Development (OECD) area edged up to 4.2% in September, from 4.1% in August, according to data released on Wednesday.

According to Anadolu Agency, inflation rose in 17 of the 38 OECD countries in September, with the consumer price index (CPI) at or below 2% in seven countries. On the other hand, it declined in seven countries and remained stable or broadly stable in 14.

The report highlighted that year-on-year energy inflation in the OECD rose sharply to 3.1% in September, from 0.8% in August. This increase is attributed to a base effect from a significant drop in energy prices between August and September 2024. Energy prices rose in 34 countries year-on-year, with nine of these countries experiencing lower energy prices than a year earlier but at a slower pace of decline compared to the previous 12 months.

Meanwhile, food inflation in the OECD area remained stable at 5% in September, following a sharp increase in August. Core inflation, which excludes food and energy, edged down to 4.2% in September, from 4.4% in August.

In the Group of Seven (G7), annual inflation ticked up to 2.8% in September, from 2.7% in the previous month. Energy inflation in the G7 rose markedly, turning positive for the first time since January. In the Group of 20 (G20), inflation was also broadly stable at 3.8% in September, with consumer prices rising in Indonesia and falling in Argentina and India.

In the eurozone, annual inflation as measured by the Harmonized Index of Consumer Prices edged up to 2.2% in September, from 2.1% in August. Food inflation fell, while the decline in energy prices slowed further. According to Eurostat's flash estimate, in October 2025, year-on-year headline inflation in the euro area remained broadly stable at 2.1%, with a decline in energy inflation to minus 1.0% while core inflation is estimated to have been stable at 2.4.
