Switzerland’s consumer price inflation accelerated modestly in September 2026, with the Consumer Price Index (CPI) rising 1.0% year-on-year, up from 0.8% in August 2026. The latest data, updated on 1 October 2026, indicate a slight firming of price pressures in the Swiss economy.

The figures are based on a year-over-year comparison, where the current reading measures price changes in September 2026 relative to September a year earlier, while the previous indicator reflected the change in August 2026 versus the same month a year before. The uptick from 0.8% to 1.0% suggests that inflation, though still subdued by international standards, has edged higher as the third quarter draws to a close.

This gradual increase will be closely watched by financial markets and policymakers, as it may influence expectations around the Swiss inflation trajectory heading into the final quarter of 2026. With inflation still contained, the data provide a nuanced picture of a price environment that is firming but remains far from levels seen in many other advanced economies.
