The Consumer Price Index rises to 4.9% year-on-year in September, the highest rate since February 2023. Diesel prices increase by 34% and petrol by 27.5%, while eggs rise by 12.3%.
The Consumer Price Index (CPI) stood at 4.9% year-on-year in September, the highest rate since February 2023, according to data confirmed by the National Institute of Statistics (INE). This spike breaks the trend of moderation seen in previous quarters and puts pressure back on family budgets.
The increase in energy and transport costs explains this shift, as reported by noticiasciudadanas.com. Over the past year, the price of diesel has risen by 34%, while petrol has seen a 27.5% year-on-year increase. This rise not only affects individual mobility but also imposes immediate cost pressures on the distribution chain and goods transport.
In supermarkets, the high prices persist. Eggs have recorded a year-on-year increase of 12.3%, solidifying their position as one of the fresh foods that have become most expensive over the past twelve months.
The sharp rise in energy and transport costs has been the main trigger for this spike, interrupting the moderation path that inflation had been showing in previous quarters.
The impact is not uniform across the territory. Castilla-La Mancha and Galicia lead the regional scale with a CPI of 5.5% year-on-year, six tenths above the national average. Both communities are more severely affected by the rising costs of transport and agro-food inputs.
Economic analysts warn that a CPI close to 5% directly erodes the purchasing power of wages and family savings, and threatens to slow down internal consumption in the last part of the year. The focus is now on the evolution of international prices of energy commodities and on possible corrective measures from administrations to mitigate the impact on the most vulnerable sectors.
