FX.co ★ Spain’s Monthly Inflation Cools as September CPI Slows to 0.3%

Spain’s consumer price inflation eased markedly on a month-over-month basis in September, with the CPI rising 0.3%, down from a 0.7% increase previously recorded. Both the prior and current readings refer to September 2026, highlighting a clear moderation in the pace of price growth when comparing the latest month to the one before it.

The data, updated on 14 October 2026, show that while prices are still rising, they are doing so at a slower monthly rate than in the previous comparison period. The current 0.3% figure reflects the change in prices from August to September, whereas the earlier 0.7% reading captured the change from July to August, indicating a cooling inflation momentum in Spain as the third quarter progressed.
