Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints - Methanol: Port inventory has increased significantly, with high imports and actual inventory. The supply in the inland region is expected to return, and the traditional demand will enter the peak season later. It is necessary to pay attention to whether the demand can be supported after the supply in the inland region returns. If the inventory deteriorates significantly, methanol is expected to see a valuation correction [2]. - Polyethylene: The inventory of the two major oil companies is neutral year - on - year. The two major oil companies are accumulating inventory, while the coal - chemical industry is reducing inventory. The overall inventory is neutral. The 09 basis is around - 150 in North China and - 100 in East China. The import profit is around - 100, with no further increase for the time being. The non - standard HD injection molding price is stable, and other price differences are fluctuating. The number of maintenance in August has decreased month - on - month, and the domestic linear production has increased month - on - month. Attention should be paid to the LL - HD conversion and the US quotation. The pressure from new plants in 2025 is relatively large, and the commissioning of new plants should be monitored [7]. - Polypropylene: The upstream two major oil companies are accumulating inventory, while the middle - stream is reducing inventory. In terms of valuation, the basis is - 60, the non - standard price difference is neutral, and the import profit is around - 800. Exports have been performing well this year. The non - standard price difference is neutral. The PDH profit is around - 200, propylene is fluctuating, and the powder production start - up rate is stable. The拉丝 production scheduling is neutral. The supply in June is expected to increase slightly month - on - month. The current downstream orders are average, and the raw material and finished - product inventories are neutral. Under the background of over - capacity, the 09 contract is expected to face moderate to excessive pressure. If exports continue to increase or there are many PDH plant maintenance, the supply pressure can be alleviated to a neutral level [7]. - PVC: The basis is maintained at 09 - 150, and the factory - pick - up basis is - 450. The downstream start - up rate is seasonally weakening, and the willingness to hold inventory at low prices is strong. The inventory reduction of the mid - upstream has slowed down. The northwest plants are undergoing seasonal maintenance in summer, and the load center is between the spring maintenance and the high production in Q1. Attention should be paid to the commissioning and export sustainability from July to August. The recent export orders have decreased slightly. The coal sentiment is positive, the cost of semi - coke is stable, and the profit of calcium carbide is under pressure due to PVC maintenance. The FOB counter - offer for caustic soda exports is 380. Attention should be paid to whether the subsequent export orders can support the high price of caustic soda. The comprehensive profit of PVC is - 500. Currently, the static inventory contradiction is accumulating slowly, the cost is stable, the downstream performance is average, and the macro situation is neutral. Attention should be paid to exports, coal prices, commercial housing sales, terminal orders, and start - up rates [7]. 3.
