Updated base year for CPI and effect on Debt Office’s inflation-linked bonds

News 16 lokakuuta 2025

As of 2026, Statistics Sweden (SCB) will update the base year for the Swedish Consumer Price Index (CPI), from 1980 to 2020. The change of base year will affect how the pricing of the Debt Office’s inflation-linked bonds is calculated as of March 2026.

In conjunction with the change of base year, SCB will publish a rebasing factor on its website. To calculate the index factor for outstanding inflation-linked bonds, the rebasing factor can be applied to re-scale the CPI with base year 2020 to reflect the former series. Accordingly, the base index will not be updated.

For more information on SCB’s rebasing factor and instructions on calculating the index factor, see the Debt Office's Terms for government bonds.

When the Debt Office introduces new inflation-linked bonds, the base index will be obtained using CPI with base year 2020.
