FX.co ★ Iceland’s Inflation Momentum Builds as September CPI Doubles Month‑on‑Month

Iceland’s consumer price dynamics strengthened in September 2026, with the month-on-month Consumer Price Index (CPI) increase rising to 0.4%, up from 0.2% in August 2026. The latest data, updated on 29 September 2026, indicate that price pressures have gained pace compared with the previous month.

On a month-over-month basis, the “actual” September reading reflects the change in prices from August to September 2026, while the “previous” 0.2% figure shows the change from July to August 2026. The doubling of the monthly rate suggests a pickup in inflationary momentum, which will be closely watched by policymakers, investors, and businesses assessing the near-term outlook for costs and pricing in Iceland’s economy.
