The recent decline in international oil prices has failed to deliver the anticipated benefits to the polyester supply chain. As the Strait of Hormuz gradually resumes navigation, crude oil costs have fallen, but the industry chain has become mired in a zero-sum game over volume, price, and margins. The three key players—upstream raw material suppliers, midstream filament yarn producers, and downstream weaving mills—hold conflicting demands: upstream wants filament yarn plants to raise operating rates to absorb PTA inventory, downstream expects filament yarn prices to correct before restocking, while midstream producers are defending their profit margins through output cuts. This standoff defines the current polyester market.
Background: Cost Channel Weakens, but Transmission Breaks
The direct trigger for the oil price drop was the US-Iran peace agreement facilitating Hormuz Strait navigation, raising expectations of restored crude supply and pushing prices back to pre-conflict levels. For the polyester industry, this should have been a cost relief, but pricing battles across the chain prevented smooth transmission. In July, PX and PTA plants underwent heavy maintenance, further reducing operating rates. However, from August onward, as refineries restart and shipping resumes, raw material supply shortages will gradually ease. This means that if the polyester end does not lift operating rates, upstream destocking pressure will intensify.
China Customs data shows PTA exports grew about 15% year-on-year in the first half, yet domestic polyester operating rates fell from 92% in June to 86% in July. This divergence indicates that upstream supply cuts have not effectively translated into downstream demand. Industry data reveals that PTA social inventory, though down from its year-high, remains at a multi-year high for the same period.
Industry Impact: Filament Yarn Cuts Become Core Leverage, Downstream Wait-and-See Spreads
Filament yarn producers are the toughest players in this game. In past years, every time raw material prices dropped, they followed with promotions, compressing processing margins and turning them into mere 'conveyors' for upstream. Now, they have proactively cut operating rates to about 70%, aiming to lift per-ton processing profits from around CNY 100 to over CNY 500. The logic is clear: if they cut prices, downstream will expect further declines and delay purchases, worsening inventory pressure. Thus, they prefer to sacrifice volume to protect margins.
Downstream weaving mills are stuck in a 'loss on every order' situation. Before the oil crash, filament yarn prices were high, and terminal orders could not raise prices, making every purchase a loss. Now that costs have collapsed, filament yarn prices remain stubborn. Downstream believes current processing margins are 'unreasonable' and refuses to restock. In clusters like Shaoxing and Wujiang, operating rates for texturing and weaving have fallen from 75% in June to 65% in July, with mills adopting a wait-and-see approach, waiting for filament yarn prices to correct below breakeven.
- Upstream (PTA): Producers want filament yarn plants to raise operating rates to absorb inventory, but output cuts have weakened direct PTA demand, compressing PTA processing margins below CNY 300/ton, near breakeven.
- Midstream (Filament Yarn): The output-cut strategy works short-term, but inventory days have risen from 15 to 22. If downstream remains on the sidelines, inventory pressure will force a strategy shift.
- Downstream (Weaving): Waiting for price corrections is rational, but prolonged waiting may miss the peak season order window.
Practical Advice
For Buyers - Monitor filament yarn inventory: If it exceeds 25 days, producers may be forced to offer discounts, creating buying opportunities. - Lock in costs via forward contracts: PTA futures contango reflects bearish expectations; consider hedging on futures. - Negotiate price protection agreements with filament yarn mills: Some may accept 'price protection + phased delivery' to reduce single-purchase risk.
For Exporters - Evaluate combined impact of FX and freight: RMB exchange rate fluctuations and rising shipping costs may offset raw material savings; calculate total cost before quoting. - Watch Southeast Asian capacity: New polyester capacity in Vietnam and India may divert orders; preemptively develop differentiated products. - Leverage export tax rebates: Some chemical fiber product rebates have been raised to 13%; optimize pricing strategies to enhance competitiveness.
The current polyester supply chain standoff is essentially a profit redistribution game. In the short term, filament yarn producers hold the upper hand through output cuts, but if downstream demand remains weak, inventory pressure will force one side to blink. For market participants, tracking filament yarn inventory and PTA processing margins will be key to identifying the turning point.
