When processing margins fall below breakeven, collective industry action often proves more direct than policy intervention. On August 15, major Chinese polyester staple fiber (PSF) producers jointly launched a self-rescue plan centered on coordinated output cuts, controlling new capacity, and abandoning vicious low-price competition. This move came against a backdrop of a 70.36% industry operating rate in July, ample spot supply, persistently weak downstream demand, narrowing processing fees, and widening losses.
Cost vs. Supply Dynamics
Raw materials show a differentiated but firm pattern. For PTA, delayed restarts of key units and port disruptions due to rainfall in East China pushed spot basis to near RMB 300/ton, with August social inventory expected to hit a 44-month low. MEG is similarly tight, with reduced imports due to Middle East tensions and concentrated domestic maintenance, pulling East China port inventories to a 15-year low and spot premiums up to RMB 540/ton in early August. Low inventories provide solid cost support for PSF.
However, this support is not sustainable. Later, restart of maintenance units will increase feedstock supply, weakening cost support. This implies the current high basis and low inventory may be temporary. Once supply recovers, PSF prices will rely more on its own supply-demand fundamentals.
Can Output Cuts Reverse the Downturn?
This round of cuts is proactive, unlike passive shutdowns from equipment failures. Leading producers in Jiangsu, Zhejiang, and Fujian—core production areas—are all participating, covering mainstream direct-spun capacity. Industry estimates suggest that if cuts are effectively implemented, the operating rate could drop from 70.36% to around 67%, reducing monthly supply by about 30,000 tons, which would ease spot oversupply and prevent deep price declines.
Yet medium- and long-term uncertainties remain. Execution may be flexible: once prices rebound and processing margins recover, cash-strapped firms might reduce cut intensity. New capacity is postponed, not canceled; once the industry turns profitable, shelved capacity could return. More critically, demand is the core constraint. If September downstream orders fail to improve, supply contraction alone cannot sustain a rally.
Transmission to Keqiao Market
As a national textile trading hub, Keqiao Light Textile City saw subdued gray fabric transactions in August, with weavers and traders cautious, operating rates low, and purchasing on a need-basis. PSF-related fabric sales were dominated by small, scattered orders, with only a few foreign directional orders. Raw material price increases are difficult to pass through to fabric end-products, and fabric price hikes face significant resistance.
After output cuts, tighter feedstock supply and higher procurement costs for traders may limit fabric price cuts and ease low-price competition. However, without a clear order recovery, fabric price increases remain difficult. Keqiao's trading activity is a key window to gauge the realization of the "golden September" demand. If new and repeat orders do not pick up materially, and weavers' restocking remains need-based rather than proactive, the price-boosting effect of upstream cuts will be greatly diminished.
Price Outlook
Overall, this coordinated output cut can provide significant support to PSF prices. From late August to early September, output cuts will stabilize and strengthen the market, with processing margins gradually recovering. In mid-to-late September, the market will oscillate upward as it balances weakening costs and demand recovery. A one-sided rally is unlikely; the biggest risk is supply rebound after margin recovery.
For industry participants, key indicators to monitor include the actual implementation of output cuts, restart progress of upstream units, yarn mill operating rates, terminal orders, and downstream restocking willingness. First-tier signals from Keqiao's gray fabric transactions, weaving utilization, and fabric export orders will be critical to validate demand realization.
