Spain’s annual inflation rate accelerated to 4.9% in September 2026, its highest level since March 2023, up from 4.3% in August and the 4.7% forecast, according to preliminary estimates. The acceleration was driven mainly by higher prices for fuel and lubricants for personal vehicles, which increased in September 2026 compared with a decline in the same month of 2025. It was also influenced by tour packages, whose prices fell less sharply than they did in September 2025.
