Polyester Industry Chain Faces Promotion Fatigue, Inventory Elasticity Could Be Key in H2

Promotional discounts are failing to generate orders, as the polyester industry chain experiences unprecedented 'rational coldness.' A late-June promotion saw production-to-sales ratios hover around 70%, plunging to near 30% the following day, with downstream weaving mills showing little interest. This is not an isolated event but a signal of deep structural adjustments.

Cost Ceiling Lowers Crude oil premiums are being stripped away. With the reopening of the Strait of Hormuz and stranded tankers departing, the short-term energy supply shock from Middle East tensions has eased significantly. Morgan Stanley downgraded its oil price forecast twice in two weeks, shifting focus back to global oversupply, with Q3 and Q4 Brent crude averaging $75 per barrel. This means the rigid cost support for polyester filament yarn has weakened substantially, making the wild price surges seen earlier this year unlikely. Although polyester plants still face high raw material costs, the future cost curve is likely to flatten or even decline, altering their room and incentive for price concessions.

Downstream 'Extreme Rationality' and Inventory Overhang Demand-side weakness is more concerning than costs. Downstream weaving mills have entered an 'extreme rational' mode, refusing to restart machines without confirmed orders. Profits over the past two years have been severely squeezed, leaving companies with zero flexibility. Fabric price elasticity is poor, and the breakeven point between inventory and fresh grey fabrics remains in fierce contention. Polyester plant inventories are accumulating: POY at 30 days, FDY at 35.7 days, and DTY at 41.8 days, with stocks still rising. If downstream demand remains sluggish, polyester filament yarn may face continued gradual price declines or a more aggressive inventory clearance.

Inventory Elasticity Opportunity in H2 Yet risks also harbor opportunities. Current stockpiling across the chain is cautious, with limited capacity utilization in H1, leaving overall market inventories relatively low compared to the past two years. Once demand recovers—whether through a hit fabric category or seasonal release—short-term supply-demand mismatches could restore fabric price elasticity. Last year's 'New Chinese-style' fabric boom is a case in point. The most likely trigger now is summer sun-protection apparel, but frequent heavy rainfall this year has delayed high temperatures and thus demand. If weather improves in H2 or another category emerges, inventory elasticity could quickly translate into price elasticity.

Practical Recommendations ### For Buyers - Current polyester prices are in a cost-bargaining zone. Focus on concentrated promotional periods from polyester plants to build positions in batches, avoiding chasing highs. - Monitor weather and end-user apparel orders closely. If summer sun-protection fabric demand picks up in July-August, lock in some low-cost raw materials early. - Establish flexible monthly procurement agreements with suppliers to leverage their inventory pressure for better pricing and reduce cost volatility.

For Exporters - Overseas clients are increasingly price-sensitive. Include raw material price fluctuation buffers in quotes to protect margins. - While short-term Middle East risks have eased, long-term stability of the Strait of Hormuz remains uncertain. Diversify sourcing channels. - Use potential H2 supply-demand mismatches to proactively pitch high-value inventory fabrics to clients, capturing market share early.
