FX.co ★ Spanish Inflation Accelerates as August CPI Climbs to 4.3% Year-on-Year

Spain’s consumer price growth quickened in August, with the country’s CPI rising 4.3% year-on-year, up from 3.6% previously, according to data updated on 15 September 2026.

The August reading, measured on a year-over-year basis, indicates that prices in Spain are now 4.3% higher than in August a year earlier. The prior figure of 3.6% was also based on a comparison with the same month of the previous year, highlighting a clear acceleration in inflation between the two latest data points.

The pickup in the Spanish CPI suggests mounting price pressures in the economy during August 2026. Investors and policymakers will be watching upcoming releases closely for confirmation of whether this marks the start of a renewed inflationary trend or a temporary spike in consumer prices.
