Key drivers behind the polyester price surge

Polyester, also known as polyethylene terephthalate fiber, is a downstream petrochemical textile raw material. The sharp uptick on September 7th stems primarily from rising crude oil prices, which have pushed upstream feedstock costs higher, notably for PX and PTA. This has strengthened cost-side support across the entire polyester supply chain.

Simultaneously, downstream buyers are rushing to secure inventory amid fears of further price increases, accelerating the drawdown of existing stockpiles and adding yet another layer of upward pressure on spot prices.
