Sweden’s CPIF (CPI at constant interest rates) rose to 1.5% year-over-year in September 2026, more than doubling from the previously reported 0.7% pace. Both readings are measured as annual changes, comparing each September result with the same month a year earlier.
The latest figure, updated on 14 October 2026, signals a notable pick-up in underlying inflationary pressure as captured by the CPIF gauge. The previous indicator, also for September 2026, showed a significantly softer 0.7% increase versus a year earlier, underscoring the scale of the revision in the annual comparison. Investors and policymakers will now assess whether this stronger-than-expected move in CPIF marks the start of a more sustained firming in Sweden’s inflation backdrop or a temporary adjustment in the data.
The comparison framework used for both the current and previous indicators is strictly year-over-year: the “actual” value reflects the change in prices in the reported month against the same month a year prior, while the “previous” value captures the corresponding year-over-year change as last reported for that month. This consistent basis highlights the sharp step-up in Sweden’s CPIF inflation profile now indicated for September.
