PTA：供需预期转弱但成本端偏强 PTA僵持震荡

Market Overview - On July 7, PTA futures showed a weak fluctuation, with a quiet spot market and weak basis, primarily driven by traders' negotiations, with sporadic offers from polyester factories [1] - The mainstream spot basis was reported at 09+103, with transaction prices ranging from 4790 to 4830 RMB/ton [1] Cost Analysis - As of July 7, the PTA spot processing fee was around 265 RMB/ton, while the TA2509 contract processing fee was 332 RMB/ton [2] Supply and Demand Dynamics - Supply: Last week, Yisheng New Materials increased its load to 3.6 million tons, Hengli restarted 2.2 million tons, and Weilian Chemical had 2.5 million tons offline, resulting in PTA load rising to 78.2% (+0.5%) [3] - Demand: Some polyester facilities were under maintenance, while others increased their load, leading to a decline in polyester's overall load to 90.2% (-1.2%). On July 7, the price of polyester filament decreased by 50-150 RMB, indicating weak overall sales [3] - The current market is in the off-season with rising fabric inventory, and there is a high probability of continued downward pressure on filament prices [3] Price Outlook - The repair intensity of PTA facilities in July is moderate, and with new PTA facilities operating stably, there are expectations of reduced production in downstream polyester factories and continued weak terminal demand, leading to a bearish supply-demand outlook for PTA [4] - Despite short-term support from strong oil prices and tight PX supply-demand expectations, the absolute price rebound for PTA remains limited due to accelerating negative feedback from the terminal [4] - The strategy suggests that TA will fluctuate in the range of 4600-4900, with a bearish bias at the upper end [4]
