Group One Refinery Closures Tighten Supply Every Year
Refiners have been closing solvent-refining Group One capacity in favour of hydrocracked Group Two and Three base oils for two decades, and each closure removes wax output permanently rather than temporarily. Only 22% of global base oil capacity still produces wax, against well over half in the early 2000s. European and North American closures have been heaviest. The commercial consequence is that supply falls on a schedule set by base oil economics, entirely independent of wax demand, which is why wax pricing has decoupled from crude oil movement since roughly 2019.
