The polyester chain saw a broad uptick in the latest trading session, with PTA futures rising 0.59% as market sentiment warmed. But stripping away the emotional layer reveals a stark contrast between supply-side signals and demand weakness. Upstream PX plant maintenance has intensified, PTA capacity utilization has dropped to its lowest since October 2021, while downstream weaving operating rates fell 8 percentage points year-on-year.
Supply Side: Unprecedented PX and PTA Maintenance
Pressure on the PX supply side is mounting. A 4-million-ton-per-year PX unit at Shenghong was shut down at the end of June for 45 days of planned maintenance. A 660,000-ton-per-year PX line at Hainan Refining & Chemical has also reduced output, expected to last three months. Industry data shows domestic PX operating rates will fall below 60% in early July, a historic low, creating a clear production gap and boosting destocking expectations for downstream PTA.
The PTA maintenance wave has been building since April, with total capacity involved in shutdowns or output cuts exceeding 22 million tons, over 20% of domestic capacity. Daily capacity utilization dipped to around 60%, the lowest since October 2021. The scale of pending maintenance in June-July remains large, keeping utilization low. Two key variables are whether maintenance compliance drops when processing margins recover and the restart pace of idle units.
Demand Side: Off-Season Weakness and Weaving Caution
July marks the traditional off-season for polyester end-users. Weaving operating rates in Jiangsu and Zhejiang averaged 52.4% in June, up 1 percentage point month-on-month but down 8 percentage points year-on-year. This gap highlights the fragility of demand recovery. While autumn/winter fleece fabrics have seen localized improvement, the market lacks bulk orders, and mills show little willingness to raise operating rates. Caution ripples up the chain, pressuring polyester operating rates to stay low.
The market remains in a 'waiting for orders' state. The timing of a turnaround in second-half new orders is critical. Without end-user demand, even strong upstream maintenance won't sustain price rebounds.
Price Outlook: Crude Dominates Short-Term, Demand Drives Medium-Term
In the short term, PTA prices will closely track crude oil. The Strait of Hormuz gradually resuming navigation and a strong dollar have erased all geopolitical risk premiums from oil prices, reducing downward momentum. But crude's direction remains uncertain, making it hard for PTA to trend independently.
Medium-term logic hinges on end-user demand. Industry consensus holds that PX and PTA destocking expectations provide price support, but rebound momentum is lacking. Only when weaving orders pick up and operating rates recover can upstream supply tightening translate into a price uptrend. Key second-half watchpoints are autumn/winter fabric order placements and inventory digestion across the chain.
