As announced on July 8, the Final Demand-Intermediate Demand price indexes (FD-ID price indexes) has been rebased, changing the base year from 2015 to 2020.
The Bank plans to begin monthly releases of the 2020 base FD-ID price indexes from July 29, when figures for June 2025 are to be published.

The following series are available on the page of <Satellite series> Final Demand-Intermediate Demand price indexes (FD-ID price indexes) (2020 base).

Basic Series: Indexes of January 2015-May 2025

Special Series: Indexes of January 1970-May 2025

  1. *1 Indexes for both series before December 2019 are long time-series constructed using the linkage coefficient.
  2. *2 In the Corporate Goods Price Index and the Services Producer Price Index, which are used to calculate the FD-ID price indexes, preliminary figures of the monthly (quarterly) indexes are subject to revision in each of the subsequent three months (one quarter) as additional information becomes available. Consequently, the FD-ID price indexes may also be revised based on the revision of these underlying data.

For detailed information on the rebasing, please refer to the Explanation of Final Demand-Intermediate Demand price indexes (FD-ID price indexes) (2020 base) [PDF 660KB].
