In mid-August, China's polyester staple fiber (PSF) industry witnessed a collective action: major producers jointly cut production to support prices and repair processing margins. This move comes against a backdrop where cost-driven gains from July have been eroded by weak demand, and industry losses are widening. Whether the cuts can truly reverse the situation hinges on one key variable: whether downstream orders are willing to pay higher prices.
Event Background
In July, PSF prices were disturbed by international geopolitical tensions, with East China spot prices hitting 7,675 yuan/ton. However, easing US-Iran tensions in early August reduced the geopolitical risk premium in crude oil, weakening the feedstock pull. Meanwhile, expectations of PTA and MEG unit restarts weighed on the polyester chain's valuation. By mid-August, feedstock strength lifted PSF prices again.
Feedstock markets showed a differentiated but strong pattern. Two core PTA units delayed restarts, and rainfall disrupted port loading in East China, tightening spot supply, with basis approaching 300 yuan/ton. August social inventory is expected to hit a 44-month low. MEG also remained strong, with import arrivals declining due to Middle East tensions and strait navigation issues, coupled with concentrated domestic maintenance, pushing East China port inventory to a 15-year low. In early August, spot premium reached as high as 540 yuan/ton. However, both PTA and MEG have planned restarts later, posing a risk to cost support.
The root cause of industry losses is supply-demand mismatch. In July, PSF industry operating rate rose to 70.36%, with ample spot supply and new capacity planned for H2. Downstream demand remained weak, with limited order growth, high finished goods inventories at yarn mills, and procurement limited to just-in-time replenishment, lacking active stockpiling.
Industry Impact
On August 15, major PSF producers jointly launched a self-rescue plan, including controlling new capacity, postponing restarts of existing units, increasing production cuts, and abandoning vicious price competition. Leading enterprises in Jiangsu, Zhejiang, and Fujian all participated, covering mainstream direct-spun capacity, marking the industry's entry into a production-cut profit-protection cycle.
In the short term, supply contraction can provide bottom support. If the self-discipline measures are effectively implemented, the operating rate could fall from 70.36% to around 67%, reducing monthly supply by about 30,000 tons, alleviating spot oversupply. Coupled with low inventories of some brand products, tighter spot circulation could prevent deep price declines.
However, execution flexibility exists. Once prices rebound and margins improve, some cash-strapped enterprises may reduce cut levels and restore loads. New capacity is only postponed, not canceled; once the industry turns profitable, shelved capacity will still be released. Demand remains the core constraint for upward movement. If September terminal orders do not improve significantly, supply contraction alone cannot sustain a strong rally.
Keqiao Textile City, a core trading hub, reflects downstream weakness. In August, a traditional off-season, grey fabric transactions contracted, weavers and traders remained cautious, operating rates stayed low, and purchasing was mostly on-demand. PSF-related fabric sales were dominated by small and scattered orders, with only a few foreign directional orders. Upstream price increases are difficult to pass through to downstream fabric terminals.
Practical Recommendations
Overall, the coordinated production cuts can provide clear bottom support for PSF prices. From late August to early September, cuts will stabilize and strengthen the market, gradually repairing processing margins. From mid-to-late September, the market will fluctuate between weakening costs and demand recovery, maintaining an upward but volatile trend. The biggest risk lies in supply rebound after margin recovery.
