Flash CPI: Inflation rate 1.1 percent in September 2026

”The preliminary inflation rate according to the CPI and the CPIF increased in September, mainly due to higher energy prices,” says Carl Holmberg, statistician at Statistics Sweden.

According to preliminary statistics, the inflation rate according to the CPI increased from 0.3 percent in August to 1.1 percent in September. The monthly change for the CPI from August to September was 0.9 percent.

The preliminary inflation rate according to the CPIF (Consumer Price Index with fixed interest rate) increased from 0.7 percent in August to 1.5 percent in September. The monthly change for the CPIF from August to September was 0.9 percent.

CPIF-XE (CPIF excluding energy) was unchanged at 0.5 percent from previous month according to preliminary numbers. The monthly change for the CPIF-XE from August to September was 0.1 percent.

The CPI flash estimates are preliminary estimates published five working days before the official publication. For the flash estimates, only CPI, CPIF, and CPIF-XE at the aggregated level are published as well as rate of changes for divisions and special aggregates. More detailed information and definitive figures will be available on October 14.

Different measures of inflation

Statistics Sweden calculates different measures of inflation for different purposes. In Sweden, the change in the Consumer Price Index (CPI) is the most common measure of inflation, but the CPIF is the measure that the Riksbank uses as its target variable for the monetary policy. The CPIF includes the same goods and services as the CPI. The difference between the CPI and the CPIF is that in the CPIF, household mortgage interest rates are held constant. This means that the effect of changes in household mortgage interest rates is only captured in the CPI and not in the CPIF.
