Platts to update weightings used for global petrochemical indices
Platts, part of S&P Global Commodity Insights, will update the weightings used in the Platts global petrochemical indices to reflect production capacities in 2025, effective Sept. 1, 2025.
The updates will reflect the changes in production capacities within each region, including shifts in global production ratios amid increasing capacities in Asia.
Platts first proposed the change on July 10 in a subscriber note available here: https://www.spglobal.com/commodity-insights/en/pricing-benchmarks/our-methodology/subscriber-notes/071025-platts-proposes-to-update-weightings-used-for-platts-global-petrochemical-indices
Currently, the weightings for Platts daily global petrochemical indices for ethylene, propylene, benzene, toluene, paraxylene, low density polyethylene and polypropylene homopolymer are based on production capacity as of 2022. These indices are calculated as weighted averages of daily assessments for Asia, Europe, and the US.
The Platts Global Petrochemical Index is the weighted average of seven basic global indices, described above.
Under the change, Platts will update the weightings for each index by region as follows:
