The No. 2 2.2 million-ton PTA unit of Yisheng Ningbo was shut down on November 20 and restarted on December 24. PriceSeek's analysis of PTA, Bull-Bear Score: -1 The restart of Yisheng Ningbo's 2.2 million-ton unit significantly increases PTA supply, exerting downward pressure on spot prices. Combined with PTA futures data (e.g., the settlement price of the 2605 contract at 5,142 yuan/ton, down 10 yuan for the day), the expectation of increased supply reinforces short-term bearish sentiment, potentially suppressing price rebounds in near-month contracts. Polyester Staple Fiber, Bull-Bear Score: 0.5 Increased PTA supply reduces raw material costs, benefiting the decline in polyester staple fiber production costs. Based on futures data (e.g., the settlement price of the 2605 contract at 6,576 yuan/ton, with a decrease in open interest), improved cost conditions may support spot profit margins. However, weak terminal demand limits upward momentum, resulting in a neutral-to-slightly positive overall impact. Polyester FDY, Bull-Bear Score: 0.5 The restart of PTA reduces raw material procurement costs, providing a slight positive impact on the production side of polyester FDY spot prices and potentially alleviating cost pressures for enterprises. However, due to the lack of direct futures data, attention should be paid to changes in downstream textile demand. Under the current market supply-demand balance, the impact remains limited. Polyester POY, Bull-Bear Score: 0.5 The cost reduction resulting from increased PTA supply provides marginal support for polyester POY spot prices. However, constrained by high overall inventory and weak demand in the chemical fiber industry, the actual price-boosting effect is neutral. It is recommended to evaluate in conjunction with terminal order dynamics. Polyester DTY, Bull-Bear Score: 0.5 The downward pressure on raw material PTA prices translates to reduced production costs for polyester DTY spot prices, benefiting processing margins. However, sluggish consumption in the downstream textile market may partially offset the positive effects, resulting in a neutral-to-slightly positive short-term price movement.
