FX.co ★ Spanish Inflation Momentum Cools in September as MoM CPI Slows to 0.3%

Spain’s inflation momentum eased in September 2026, with the month‑over‑month Consumer Price Index (CPI) rising 0.3%, down from a 0.7% increase recorded in August. The fresh data, updated on 29 September 2026, point to a noticeable deceleration in short‑term price pressures across the Spanish economy.

The comparison is based on monthly changes: the current 0.3% figure reflects the change in prices from August to September 2026, while the previous 0.7% reading captured the movement from July to August 2026. The slowdown suggests that, on a month‑to‑month basis, price growth has roughly halved, potentially easing some immediate inflationary concerns for households and policymakers.

While the data do not provide details on individual components, the softer overall MoM print may indicate a more balanced pricing environment heading into the final quarter of the year. Market participants will be watching upcoming releases to see whether September’s moderation marks the start of a trend or a temporary pause in inflationary pressures.
