PPI Updates Commodity Weight Allocations for the Final Demand–Intermediate Demand Aggregation Structure
Effective with the release of data for January 2026 on February 27, 2026, the Bureau of Labor Statistics (BLS) will update weight allocations used to calculate the Producer Price Index (PPI) Final Demand-Intermediate Demand (FD-ID) indexes to more accurately reflect recent sales patterns. The new allocations will be based primarily on data from the 2017 Input-Output (I-O) Accounts from the Bureau of Economic Analysis (BEA). The allocations were previously based on the 2012 I-O of Accounts data. PPI commodity index weights continue to be based on shipment values from the 2017 economic census, which were applied in January 2023. It is the proportions of these commodity index weights allocated to the various FD-ID categories, including Final demand, Intermediate demand by commodity type, and Intermediate demand by production flow, that will be updated.
This allocation update will not change the PPI commodity classification system, reference base, the FD-ID aggregation structure, or historical index data. It may, however, result in substantial shifts in the relative importance figures of certain commodity components that make up the FD-ID indexes.
Relative importance figure tables for December 2025, which detail the shift in weight allocations, as well as price movements in 2025, will be available on February 27, 2026 on the BLS website at www.bls.gov/ppi/tables/. This information also may be requested from the PPI Section of Index Analysis and Public Information at ppi-info@bls.gov or (202) 691-7705.
