OECD annual inflation ticks up to 4.2% in September

ISTANBUL

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.

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.

"Year-on-year energy inflation in the OECD rose sharply to 3.1% in September, from 0.8% in August. While recent month-on-month changes have remained subdued, this year-on-year rise reflects a base effect from a significant drop in energy prices between August and September 2024," the OECD said in a statement.

The energy prices rose in 34 countries year-on-year. In nine of these, energy prices were still lower than a year earlier but declined at a slower pace than in the 12 months to August.

Meanwhile, the food inflation in the OECD area was stable at 5% in September, following the sharp increase seen 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. The consumer prices rose in Indonesia and fell 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," it added.
