Finland’s consumer prices moved sharply higher in September 2026, with the Month-over-Month Consumer Price Index (CPI) rising 0.70%, according to data updated on 14 October 2026. The move marks a notable turnaround from August 2026, when prices had fallen by 0.20% compared to July.

The latest reading signals a clear shift in short-term price dynamics: after a brief period of month-on-month deflation in August, inflationary pressures resurfaced in September. On a MoM basis, the “actual” figure for September represents the change versus August, while the “previous” figure reflects the August change versus July, underscoring how quickly price momentum has reversed within just one month.

For markets and policymakers, the swing from -0.20% to 0.70% will likely draw attention to the underlying drivers of the renewed price growth, as investors reassess expectations for inflation trends in Finland heading into the final quarter of 2026.
