The PTA main contract fell by 3.17% on January 27. The analysis is as follows: Yesterday's decline and last week's rise share the same origin, both driven by fund flows within the chemical sector. Last week, funds flowed into the chemical sector, and as a variety with relatively favorable fundamental expectations, PTA saw a significant increase in positions and rose sharply; today, funds flowed out of the chemical sector, with PTA positions decreasing by 136,000 lots, leading to another substantial decline. There has been no significant change in PTA's fundamentals; the current fundamentals are weak, but long-term expectations are strong. Against the backdrop of weakening real demand, PTA supply and demand are accumulating inventory, and the basis is weak, making it difficult to pass on rising raw material costs downstream. However, in the medium to long term, there are no new PTA capacity plans for 2026, the period of concentrated capacity commissioning has ended, and there are few planned new PTA installations over the next five years, indicating that capacity growth will slow down significantly. Meanwhile, new downstream polyester capacity continues to be commissioned. Long-term expectations for PTA remain favorable, and the logic supporting the recovery of processing fees remains intact. Looking ahead, PTA's long-term logic provides support, maintaining the view of buying on dips for hedging purposes, but attention must be paid to the follow-through of downstream demand and the realization of PX maintenance schedules. Risk warnings: Impact of macro policies; significant fluctuations in crude oil prices. Demand recovery falls short of expectations.
