Introduction:
Geopolitical tensions in the Middle East persisted around the National Day holiday, with negotiation disputes and Strait restrictions simultaneously driving up oil prices. Elevated volatility boosted feedstock costs for naphtha and paraxylene (PX), strengthening the cost side of the PTA market. On the supply front, Zhejiang Petrochemical’s 2-million-tonne PX unit underwent scheduled maintenance, while local units at Jiaxing and Dushan Energy, totaling 4.5 million tonnes of PTA capacity, also entered planned shutdowns. These events realized expectations of supply contraction. Downstream polyester prices rose in tandem with raw materials; however, all polyester categories remained in continuous losses. Facing significant cost pressure, some plants increased production cuts and maintenance schedules, leading to further declines in operating rates. Overall, recent PTA operating rates have fallen again, narrowing the pace of inventory accumulation. The market remains caught between cost-driven support and weak downstream fundamentals. Considering spot prices influenced by maintenance expectations and shipping disruptions, along with concentrated cargo ownership, spot basis levels remain firm.
Core Logic:
Costs: Ongoing geopolitical instability in the Middle East has kept cost-side markets volatile, tracking geopolitical news. Naphtha and PX prices rose concurrently, with weekly changes of +3.67% for naphtha and +2.64% for PX, providing support for PTA. However, monoethylene glycol (MEG) prices weakened, falling -2.70% week-on-week, partially offsetting the rise in total polyester feedstock costs. Overall, upstream cost centers have risen, but transmission to downstream polyester is struggling, placing severe pressure on downstream profits.
Supply and Demand:
I. Industry Profit Distribution: Cost Centers Rise, Upstream Profits Recover, Polyester Sector Faces Deep Losses Across the Board
Driven by crude oil geopolitical disturbances, industry chain prices generally rose this week. Naphtha, PX, and PTA prices increased by +3.67%, +2.64%, and +6.88% respectively. Downstream polyester products followed suit, with POY, polyester staple fiber, PET bottle chips, and polyester chips rising by +1.15%, +4.68%, +3.84%, and +3.06% respectively. Profits concentrated upstream: the PX-Naphtha spread (PXN) widened slightly to USD 357.56 per tonne, while the PTA processing margin dipped slightly by -0.84% to RMB 822.05 per tonne. High costs failed to transmit smoothly to downstream sectors, putting comprehensive pressure on polyester profits. Polyester staple fiber faced the most severe losses, while filament yarn, bottle chips, and chips were all in deficit. Polyester producers continued to hedge against losses through load reductions and production cuts, as high melt-spun costs persistently suppressed downstream production enthusiasm.
II. Supply Environment: Concentrated PTA Unit Maintenance Leads to Phased Supply Contraction and Narrower Inventory Accumulation
Zhejiang Petrochemical initiated maintenance during the National Day holiday, coinciding with the shutdowns at Jiaxing and Dushan Energy. With multiple PTA units undergoing concentrated maintenance, the weekly PTA operating rate fell to 72.22%. Supply increments were phase-restricted, significantly narrowing the pace of PTA inventory accumulation. Upstream PX spot liquidity remained tight due to geopolitical shipping risks and maritime schedule disruptions. While long-term fundamental logic still points toward increased supply, short-term concentrated maintenance has altered immediate supply dynamics, tightening spot liquidity and supporting PTA spot prices and basis levels. Future focus should be on the restart timelines of maintained units, the realization of pending maintenance plans (such as Baihong and Jiatong), and the arrival pace of PX cargoes.
III. Demand Environment: Prices Rise with Costs, but End-User Demand Shows No Substantive Recovery; Production Cuts Provide Passive Support
Polyester product prices rose following PTA increases, yet all varieties remained in loss, causing the polyester operating rate to fall further to 72.12%. Weaving sector loads remained low, with no improvement in jet looms in Shengze and Northern Jiangsu, or circular knitting machines elsewhere; dyeing and printing loads saw limited recovery. Polyester sales performance was characterized by pulses, where volume spikes were largely driven by mandatory restocking due to raw material price hikes rather than a substantive rebound in end-user textile orders. Downstream finished goods inventories remained high, with POY, FDY, and DTY stocks still in elevated ranges. Active inventory building by downstream enterprises was insufficient, with purchasing mainly restricted to just-in-time needs. Polyester factories continued to hedge losses through production cuts and load reductions, passively supporting demand. However, weak terminal consumption makes it difficult to generate sustained strong demand pull.
Conclusion:
In the short term, PTA is expected to fluctuate widely within a broad range, supported by dual factors of geopolitical costs and concentrated maintenance. Conversely, upside potential is capped by weak end-user demand, deep losses in the polyester sector, and plans to increase production cuts. In the medium to long term, once maintained units restart, inventory pressure will return, spot liquidity will improve, and the height of market price increases will be limited. Key variables to monitor include crude oil geopolitics, unit restarts, and downstream weaving demand.
