If this estimate is confirmed, year-on-year inflation (price rises compared to the same period in the previous year) in Spain in September increased by two tenths this month, after remaining at 2.7 per cent in July and August.

The rise in prices this month was mainly due to fuel and electricity, which fell, but less than in the same month in 2024, according to the INE.

As for the underlying inflation rate (without energy and fresh food products, traditionally the most volatile in the shopping basket), it fell by a tenth in September, to 2.3 per cent, according to the same estimate.

In chain evolution (comparison with the previous month), the estimate is that prices in Spain fell by 0.4 per cent in September.
