Platts to update component weighting for Platts Industrial Materials Index for 2025
Platts, part of S&P Global Commodity Insights, will update the weighting used in the Platts Industrial Materials Index [PLINM00], effective Jan. 2, 2025.
The revised weighting reflects an update in market value of the components, following a review conducted by Platts. Market value of the components are approximated by the product of the latest global production or consumption volume of the commodity and its latest two-year average price.
The weightings are reviewed annually to keep the index representative of global supply and demand trends.
