FX.co ★ Finland Slips Into Monthly Deflation as August CPI Falls 0.2% MoM

Finland’s consumer prices declined in August 2026, with the month‑over‑month Consumer Price Index (CPI) coming in at -0.20%, according to data updated on 14 September 2026. This marks a reversal from July 2026, when prices rose 0.20% compared with the previous month.

On a month‑over‑month basis, August’s negative reading indicates that overall consumer prices were lower than in July, underscoring a shift from modest inflation to mild deflation within just one month. The comparison is based on changes in prices between consecutive months: July’s “previous” figure reflected the change from June to July, while August’s “actual” figure reflects the change from July to August.

The move from +0.20% to -0.20% MoM will likely draw attention from policymakers and market participants, who monitor short‑term price movements for early signals of changing inflation dynamics in Finland’s economy.
