The Bank plans to begin monthly releases of the 2020 base SPPI from June 25, when preliminary figures for May 2024 are to be published. This paper explains, with respect to the SPPI with the new base, an overview of the number of items and weights, developments of the indexes for newly added and revised items, an analysis of changes in the index for "All items", and initiatives for improving the usability of the SPPI.
