1. Report Industry Investment Rating - No information provided in the given content 2. Core View of the Report - The plastic futures 2601 contract is expected to maintain a volatile and stable trend, driven by the cost support from stable crude oil prices, reduced polyethylene supply due to plant maintenance, and improved downstream demand during the peak season [2][5] 3. Summary by Related Catalogs 3.1 Crude Oil Price and Cost Support - The trading logic in the crude oil futures market comes from three aspects: macro - factor drive with a "tight - to - loose" macro - environment, increased supply as OPEC+ continues to expand production, and rising geopolitical premiums in the oil market. After the game between supply increase and enhanced geopolitical risks, the domestic and international crude oil prices are expected to be volatile and stable, providing cost support for plastic futures [3] 3.2 Domestic Polyethylene Supply - Since September, the weekly output of domestic polyethylene has declined slightly due to the maintenance of devices such as Yulong Petrochemical, Liaoyang Petrochemical, and Yangzi Petrochemical. As of the week of September 12, 2025, the domestic polyethylene enterprise maintenance loss was 14.62 tons, a week - on - week increase of 2.28 tons. However, considering the planned restarts and new maintenance in the second half of the month, the supply decline momentum is expected to weaken, and the weekly output may stabilize and rebound [4] 3.3 Downstream Demand - With the arrival of the "Golden September" peak season, the profits of films and packaging films have improved.

Report Industry Investment Rating No relevant content provided. Core Views Chlor - Alkali Industry - The caustic soda futures market is stabilizing, with overall commodity sentiment positive. Supply may decline due to planned maintenance, and demand from the alumina industry is weakening, while non - alumina demand is improving but with limited price support. Spot prices may stabilize, and the downside of futures prices is limited [27]. - The PVC futures market is rebounding, driven by macro - sentiment. Supply is expected to decrease due to more maintenance this week, and demand from downstream products is slightly increasing. The cost side is providing bottom support, and it is expected to stop falling in the peak season from September to October [27]. Polyester Industry Chain - For PX, supply is increasing to a relatively high level, and short - term demand has some support, but the upside is limited. It is expected to fluctuate between 6600 - 6900 in the short term [30]. - PTA's spot market liquidity is good, and the medium - term supply - demand is weak. It is expected to fluctuate between 4600 - 4800 in the short term, and TA1 - 5 should be rolled in a reverse spread [30]. - Ethylene glycol's supply - demand pattern is strong in the near - term and weak in the long - term. It is expected to reduce inventory in September but increase inventory in the fourth quarter. It is recommended to wait and see on the single - side and use EG1 - 5 reverse spread [30]. - Short - fiber's short - term supply - demand is weak, and it mainly follows raw material fluctuations. The single - side strategy is the same as PTA, and the processing fee is expected to fluctuate between 800 - 1100 [30]. - Bottle - chip's supply increases slightly, and demand may decline. It mainly follows cost fluctuations, and the processing fee is expected to fluctuate between 350 - 500 yuan/ton [30].

Demand is mainly supported by export and industrial needs, and the futures increase is mainly due to short - covering and expectation differences [39][40]. Methanol Industry - Methanol's supply in the inland is at a high level, and demand is weak due to the traditional off - season. The inventory pattern is relatively healthy, and the overall valuation is neutral. The market is swinging between high - inventory reality and overseas gas - restriction expectations, and the inventory inflection point should be monitored [42]. LLDPE - PP Industry - PP's PDH and propylene - purchasing profits are suppressed, with more unplanned maintenance and falling inventory, but the basis is still weak. PE's maintenance is at a relatively high level, with short - term low supply pressure, rising basis, and inventory reduction. Demand for new orders is poor, and the market is in a state of "decreasing supply and increasing demand" [45]. Crude Oil Industry - Overnight oil prices rose due to geopolitical conflicts, which increased concerns about supply disruptions of Russian refined oil and crude oil. The market's focus has shifted to immediate supply risks, and the oil price is likely to run along the upper edge of the shock range in the short term. It is recommended to wait and see on the single - side, and look for opportunities to widen spreads on the options side after volatility increases [48] Summary by Directory Chlor - Alkali Industry - **PVC, Caustic Soda Spot & Futures**: On September 16, Shandong 32% liquid caustic soda's price decreased by 3.0%, and Shandong 50% liquid caustic soda's price decreased by 4.4%.
