France's annual inflation rate accelerated to 3.1% in September, up from 2.4% in August, rekindling economic concerns. This surge is primarily driven by a sharp 21.3% year-on-year increase in energy prices. Final data from the National Institute of Statistics and Economic Studies confirmed figures higher than initial estimates, fueling worries over household purchasing power and mounting production costs. Additionally, the harmonized European index rose to 3.4%, underscoring the growing inflationary pressures impacting the second-largest economy in the Eurozone.
