The polyester chain saw a collective uptick in early July, with PTA futures edging up 0.59%. However, stripping away short-term sentiment, the rebound lacks a solid foundation—crude oil has erased all geopolitical risk premiums, while downstream weaving is entering a traditional off-season. The market is caught in a classic 'strong middle, weak ends' pattern.
Supply Side: PX Maintenance Wave Fuels Destocking Expectations
Concentrated PX plant maintenance from late June to early July is the core driver of this polyester chain rebound. Sinopec's 4-million-ton PX unit in Shenghong has been shut down as planned for about 45 days, while Hainan Refining & Chemical's 660,000-ton line is running at reduced capacity for three months. Industry data shows that domestic PX operating rates will fall below 60% in early July, the lowest on record.
This means the PX market will enter a substantive destocking phase in July. From a chain perspective, PX supply contraction directly bolsters PTA cost support. But this destocking is driven by supply-side contraction, not demand pull, which inherently limits price elasticity.
PTA: Low Capacity Utilization but Margin Recovery Raises Concerns
The intensive maintenance wave in the PTA sector since April continues. Over 22 million tons of capacity—more than 20% of domestic total—have been idled or reduced. Daily capacity utilization once fell to about 60%, the lowest since October 2021. With June-July maintenance schedules still heavy, utilization is expected to stay low.
Two variables require attention: first, if processing margins recover to high levels, maintenance fulfillment rates may decline as some plants delay shutdowns for higher profits; second, the restart pace of idled units. If destocking expectations materialize but terminal orders remain weak, early restarts could reverse the destocking rhythm.
Weaving Sector: Clear Off-Season Signs, Lack of Bulk Orders
The downstream weaving segment sends a clearer signal. In June, the average operating rate in Jiangsu and Zhejiang was 52.4%, up 1 percentage point month-on-month but down 8 points year-on-year. While demand for autumn/winter fleece fabrics showed localized improvement, the market lacks bulk order support, limiting mills' willingness to raise operating rates.
July is the traditional off-season for polyester end-users, which was already consensus. The key question is when autumn/winter order inflection will arrive. Historically, July-August is the window for seasonal orders, but this year brands generally carry high inventories and place orders slowly, potentially pushing the inflection point later.
Outlook: Short-Term Tracks Oil, Mid-Term Awaits Demand
Overall, PX and PTA destocking expectations provide a floor for prices. In the short term, PTA will likely track crude oil. With crude having shed geopolitical premiums and downside momentum weakening, the risk of a sharp PTA drop is low.
However, a true upward driver requires terminal demand release. If autumn/winter orders materialize in bulk by August-September, combined with low midstream inventories, the polyester chain could see a trend rally. Until then, the market will oscillate in a range with demand as the ceiling and cost as the floor.
