Report Overview - The report is a methanol polyolefin morning report released on September 2, 2025, by the Energy and Chemicals Team of the Research Center [1] Methanol Data Summary - From August 26 to September 1, 2025, the power coal futures price remained at 801, while the prices of methanol in different regions showed some fluctuations. For example, the Jiangsu spot price decreased from 2275 to 2230, and the Northwest discounted price decreased from 2680 to 2645 [2] Core View - The trading logic is that the port pressure is transmitted to the inland. Although the inland has seasonal stocking demand and new device stocking increments from Lianhong, the port will continuously form a backflow impact. Currently, the price on the disk is benchmarked against the inland price, and the inland's actions are crucial. Xingxing is expected to start operation in early September, but the inventory is still accumulating. The backflow can resolve the port pressure but will affect the inland valuation. Currently, the valuation and inventory are average, and the driving force is weak. Therefore, it is necessary to wait before bottom - fishing [2] Plastic (Polyethylene) Data Summary - From August 26 to September 1, 2025, the prices of polyethylene in different regions and forms showed a downward trend. For example, the Northeast Asia ethylene price remained stable at 840, while the North China LL price decreased from 7270 to 7170, and the East China LL price decreased from 7400 to 7290 [6] Core View - The inventory of Sinopec and PetroChina is neutral year - on - year. The upstream Sinopec and PetroChina and coal chemical industries are destocking, the social inventory is flat, and the downstream raw material and finished product inventories are also neutral. The overall inventory is neutral. The 09 basis is about - 110 in North China and - 50 in East China. The overseas markets in Europe, America, and Southeast Asia are stable. The import profit is around - 200, with no further increase for the time being. The price of non - standard HD injection molding is stable, other price differences are fluctuating, and LD is weakening. The maintenance in September is the same as the previous month, and the domestic linear production has decreased recently. Attention should be paid to the LL - HD conversion situation and the US quotation. The pressure from new devices in 2025 is large, and attention should be paid to the commissioning of new devices [6] Polypropylene (PP) Data Summary - From August 26 to September 1, 2025, the prices of polypropylene in different regions and forms showed a downward trend. For example, the Shandong propylene price increased from 6450 to 6580, while the East China PP price decreased from 6985 to 6845 [7] Core View - The upstream Sinopec and PetroChina and the middle - stream of polypropylene are destocking. In terms of valuation, the basis is - 60, the non - standard price difference is neutral, and the import profit is around - 700. The export situation has been good this year. The non - standard price difference is neutral, and the markets in Europe and America are stable. The PDH profit is around - 400, the propylene price is fluctuating, and the powder production start - up rate is stable. The drawing production scheduling is neutral. The subsequent supply 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 pressure on the 01 contract is expected to be moderately excessive. If the export volume continues to increase or there are many PDH device maintenance, the supply pressure can be alleviated to a neutral level [7] PVC Data Summary - From August 26 to September 1, 2025, the prices of PVC in different regions and forms showed some fluctuations. For example, the Northwest calcium carbide price decreased from 2350 to 2300, and the Shandong caustic soda price decreased from 887 to 882 [7] Core View - The basis is maintained at 01 - 270, and the factory - pickup basis is - 480. The downstream start - up rate is seasonally weakening, and the willingness to hold goods at low prices is strong. The inventories of the middle and upstream are continuously accumulating. The Northwest devices have seasonal maintenance in summer, and the load center is between the spring maintenance and the high production in Q1. In Q4, attention should be paid to the commissioning of new devices and the sustainability of exports. The recent export orders have slightly decreased. The coal market sentiment is good, the cost of semi - coke is stable, and the profit of calcium carbide is under pressure due to PVC maintenance. The counter - offer for caustic soda exports is FOB380. Attention should be paid to whether the subsequent export orders can support the high - price caustic soda. The comprehensive profit of PVC is - 100. Currently, the static inventory contradiction is accumulating slowly, the cost is stable, the downstream performance is average, and the macro - environment is neutral. Attention should be paid to exports, coal prices, commercial housing sales, terminal orders, and start - up rates [7]

It is advisable to consider short - term long - position opportunities on dips [6]. - For rubber, NR and RU have shifted from a stagnant - rise to a decline. Bulls focus on potential production cuts, while bears are concerned about weak demand.

Demand is in the off - season, and the price is expected to be bearish in June [20]. - For PX, the maintenance season has ended, and the load remains high. In the third quarter, PX is expected to continue to reduce inventories due to new PTA device production. After the geopolitical situation eases, it is advisable to consider long - position opportunities on dips following the trend of crude oil [22][23]. - For PTA, the load remains stable, and downstream load has decreased. In the future, supply is expected to decrease slightly, and demand is under slight pressure. After the geopolitical situation eases, it is advisable to consider long - position opportunities on dips following the trend of PX [24]. - For ethylene glycol, the supply load has decreased, and the downstream load is expected to decline from its high level.
