PTA capacity utilization fell to 60%, the lowest since October 2021, while weaving sector operating rates dropped 13 percentage points year-on-year—these two figures highlight the extreme divergence in the current polyester supply chain: upstream actively contracts supply, while downstream end demand remains mired in difficulty. On June 30, PX and PTA futures recorded gains of 0.87% and 0.91% respectively. Is this modest rebound a signal of an inventory cycle bottom, or merely a technical correction?
Maintenance Wave and Inventory Inflection
Since April, China's PTA industry launched an unprecedented wave of concentrated maintenance. Industry data shows that maintenance and capacity reduction involved over 22 million tons, accounting for more than 20% of total domestic capacity. This wave directly pushed daily PTA capacity utilization from normal levels to around 60%, the lowest in nearly four years. Social inventories subsequently entered a continuous decline, and the industry officially began a de-stocking phase.
On the PX side, the recent decline briefly broke through pre-geopolitical conflict price levels, highlighting its own tight supply situation. Hormuz Strait navigation volume has recovered to about 75% of pre-conflict levels, but shipping insurance rates remain high. As navigation conditions improve marginally, previously idled PX units may restart early, laying the groundwork for future supply increases.
Downstream Profit vs. Operating Rates
In contrast to upstream's active contraction, the downstream polyester segment presents a complex picture of 'decent margins but cautious operations.' Currently, except for polyester chips and DTY, most polyester products enjoy profit margins of 200-300 yuan per ton. However, as of June 18, the average polyester operating rate was only 80.19%, down 8.44 percentage points year-on-year, corresponding to a weekly PTA demand of about 1.34 million tons.
Weaving sector performance is even weaker. The weaving operating rate during the same period was 57%, down 13 percentage points year-on-year. Weakened end-user purchasing intentions have caused polyester filament yarn inventories to continue climbing, further suppressing the demand transmission upward. The market overall presents a three-layer structure of 'tight upstream, squeezed midstream, and weak downstream recovery,' with weak cost and demand sides remaining the main constraints on price recovery.
Seasonality and Restocking Expectations
Although currently in the traditional consumption off-season, recent orders have shown signs of recovery. With strategic reserves of various countries at low levels, there is theoretically strong restocking momentum in the market. Improved Hormuz Strait navigation conditions also provide marginal support for the PX supply side.
For buyers, current PTA prices are in a four-year low range, coupled with supply contraction from concentrated maintenance, limiting short-term downside risk. However, substantive recovery in downstream demand still requires observation of weaving operating rates and the sustainability of end-user orders. If the July-August off-season proves not so weak, restocking may start early.
