The ICIS Global Petrochemical Index (IPEX) provides a capacity-weighted measure of the average change in petrochemical prices over time.
Dating back to January 1993, historical ICIS prices for a basket of 12 essential petrochemical products in the US, western Europe and northeast Asian markets have been weighted by regional nameplate capacity to generate a monthly index value.
The ICIS Petrochemical Index (IPEX) product basket comprises ethylene, propylene, benzene, toluene, paraxylene (PX), styrene, methanol, butadiene (BD), polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) and polystyrene (PS).
