Iceland’s consumer price inflation accelerated in September 2026, with the year-on-year Consumer Price Index (CPI) climbing to 5.9%, up from 5.6% recorded in August 2026. The latest data, updated on 29 September 2026, indicate a renewed increase in price pressures after a brief period of relative stability.
Both the current and previous readings are measured on a year-over-year basis, comparing each month’s price levels to the same month a year earlier. The move from 5.6% in August to 5.9% in September suggests that inflationary momentum has strengthened slightly, underscoring ongoing challenges for households and policymakers in managing rising living costs.
The uptick may refocus attention on Iceland’s inflation outlook and monetary policy stance, as the latest figures show that price growth remains elevated and is no longer easing on a yearly comparison basis.
