PTA spot prices in East China hit 6,185 yuan per ton on July 24, significantly retreating from earlier highs. This price point reflects a rapidly tilting supply-demand balance in the industry. The basis for July main port deliveries was reported at a 168-point premium over the September futures, while August contracts settled at a 110-160 point premium, with the backwardation structure signaling a bearish outlook. Major suppliers actively sold, but buyers only replenished on dips for essential needs, resulting in subdued market negotiations.
Supply-Demand Imbalance Drives Price Correction
On the supply side, the PTA plant maintenance season has passed, with operating rates gradually rising and new capacity releases adding to supply. On the demand side, although downstream polyester plants maintain relatively high operating rates, insufficient orders in the final weaving sector have led to continuous inventory accumulation at polyester product levels. This supply-increase, demand-weakness pattern directly suppresses the upside potential of PTA spot prices. Even with high crude oil prices, cost support cannot fully transmit to the PTA segment, as downstream capacity to absorb high-priced raw materials has reached its limit.
Basis Structure Reflects Market Expectation Divergence
The current PTA futures-spot basis shows a near-strong, far-weak pattern. July delivery cargoes maintain a 168-point premium over September futures, while August cargoes drop to a 110-160 point premium, with some low-priced cargoes near the lower end. This basis structure indicates that while spot markets still have some urgent demand support, speculative sentiment on forward contracts is clearly turning bearish. Major suppliers are actively selling in the spot market, essentially locking in profits at the current favorable basis to hedge against future price declines. For traders, the backwardation means limited arbitrage opportunities, with speculative demand significantly suppressed.
Downstream Weaving Firms Shift to Conservative Procurement
Sharp price fluctuations in raw materials are changing the procurement habits of downstream weaving firms. The past 'buy on rising, not on falling' mentality has faded, replaced by a conservative 'buy as needed, replenish on dips' strategy. Fabric mills and garment factories have significantly shortened order cycles, reducing willingness to stockpile raw materials. This shift not only affects short-term PTA demand but also challenges inventory management across the polyester chain. If end-consumer markets fail to show significant recovery before the traditional peak season, midstream inventory pressure could further shift to the PTA segment, forcing upstream production cuts or price reductions.
