PTA futures have climbed back above 6,000 yuan per ton, and polyester filament spot prices followed with increases, yet transaction volumes have not expanded correspondingly. This rally, driven by supply contraction and cost escalation, is meeting with "soft resistance" from downstream weaving mills, highlighting profit distribution conflicts across the value chain.
Background
Supply-side contraction is the direct driver of the PTA surge. Since the second quarter, multiple large PTA units entered planned maintenance, coupled with a shortage of PX feedstock, pushing industry operating rates below 60%, a ten-year low. Persistent low operating rates led to inventory drawdowns, tightening spot availability, strengthening basis, and lifting spot premiums, laying a fundamental foundation for price gains. Meanwhile, no new PTA capacity has been added domestically this year, easing long-term supply expansion pressure and shifting market sentiment from bearish to cautiously optimistic.
Rising international crude oil prices have further reinforced cost support. Geopolitical conflicts disrupted energy transport routes, driving up PX prices. Cost pressures cascaded downstream, raising production costs for polyester plants. Theoretically, PTA accounts for over 60% of polyester filament production costs, so feedstock gains should translate into filament price hikes. However, actual price transmission has been sluggish.
Industry Impact
Although filament mills raised offers and some specifications saw temporary sales improvements, weaving mills showed weak willingness to chase higher prices. The terminal market is at a seasonal transition point: domestic autumn/winter fabric stocking has started slowly, while export orders have recovered less than expected, with overseas destocking pressures persisting. Weaving mill operating rates remain low compared with recent years, and greige fabric inventories have not been fully digested. Consequently, the market frequently sees "reported price increases but stagnant transaction prices," prolonging negotiations between upstream and downstream players.
This situation indicates that the current rally is cost-push rather than demand-pull. In the short term, low PTA inventories will persist, providing bottom support for filament prices, making deep corrections unlikely. However, the medium-term price ceiling depends not on upstream feedstocks but on the realization of downstream textile orders. If filament prices rise too quickly, they will squeeze the already thin margins of weaving mills, potentially triggering negative feedback that forces polyester plants to concede price cuts, leading to a pullback.
As maintenance units restart, PTA supply will gradually recover, easing tightness and weakening the upward momentum from feedstocks. If downstream weaving orders continue to improve and greige fabric inventories decline smoothly, filament prices may extend gains. Conversely, if end-demand remains weak, upside potential will be limited, and the market will likely remain rangebound amid cost-demand tug-of-war.
