Report Industry Investment Ratings - Propylene, Polyolefins, Styrene, PTA, Short Fiber, Bottle Chip, Methanol, Urea, PVC, and Glass are rated ☆☆☆, indicating a clearer long/short trend and relatively appropriate investment opportunities currently [1]. - Pure Benzene is rated ☆☆☆, suggesting a clearer long/short trend and relatively appropriate investment opportunities currently [1]. - Ethylene Glycol is rated ☆☆☆, meaning a clearer long/short trend and relatively appropriate investment opportunities currently [1]. - Caustic Soda is rated ☆☆☆, indicating a clearer long/short trend and relatively appropriate investment opportunities currently [1]. - Soda Ash is rated ☆☆☆, suggesting a clearer long/short trend and relatively appropriate investment opportunities currently [1]. Report's Core View - In the chemical industry, different products present diverse market conditions. Some products have positive short - term trends but face long - term supply - demand imbalances, while others are affected by factors such as weather, downstream demand, and production capacity changes [2][3][5]. Summary by Related Catalogs Olefins - Polyolefins - Propylene futures rose slightly. Supply is increasing, but lower prices led to better low - price sales. Polyolefins futures also rose slightly. Polyethylene has inventory pressure, and polypropylene's supply is still ample despite some improvement in the packaging sector [2]. Pure Benzene - Styrene - Pure benzene futures rebounded slightly. Its weekly production decreased, and port inventory declined, but high import expectations and poor downstream profits weakened the outlook. Styrene futures rose slightly but remained below the 5 - day moving average, with sufficient supply and weak demand [3]. Polyester - PX's strong supply - demand expectations weakened, but an oil price rebound drove up PX and PTA prices. PTA's profitability is poor. Ethylene glycol prices fell, with weak expectations. Short - fiber new capacity is limited, and demand is improving. Bottle - chip production was affected by typhoons, but long - term over - capacity is a concern [5]. Coal Chemical Industry - Methanol stopped falling. Port unloading was slow, and MTO plant operations increased, leading to port de - stocking. However, high port inventory limited price increases. Urea prices rose, but supply still exceeded demand, and the export window is closing [6]. Chlor - Alkali - PVC's supply - demand is loose, with high inventory. It may show a weak and volatile trend. Caustic soda has a weak current situation but strong future expectations, and the 2510 - 2601 spread may widen [7]. Soda Ash - Glass - Soda ash rose with glass. Soda ash production is expected to increase, and long - term supply is excessive. Glass prices rose due to industry meetings and planned price hikes. In the short - term, it may be strong, but long - term trends depend on capacity reduction [8].

The gap between domestic and imported soybeans widened, and China is accelerating the purchase of Argentine soybeans. The supply gap in Q1 next year may disappear, and the US soybean market may be pressured [2] Soybean & Soybean Meal - The decline of soybean meal futures narrowed. Affected by Argentine policies, it remains weak. Import volume should be continuously monitored. The domestic oil mill operation rate is high, and the inventory is accumulating. The short - term market is bearish, and a long - term cautious bullish view is held [3] Soybean Oil & Palm Oil - After Argentina lifted export taxes, China is speeding up soybean purchases. The supply gap in Q1 next year may disappear. Palm oil is in a production - reduction cycle. The US soybean market may be pressured, and the overall oil and oilseed prices may face downward pressure. In the medium term, soybean and palm oil are expected to trade in a range [4] Rapeseed Meal & Rapeseed Oil - The rapeseed oil - meal ratio is rising. Rapeseed meal is under pressure due to Argentine policies, low protein price difference, and seasonal demand decline. Australian rapeseed will improve domestic supply. The rapeseed oil - meal ratio is expected to rise, and the rapeseed futures price will be under short - term pressure [6] Corn - Dalian corn futures fluctuated strongly. The market is optimistic about the new - season output, but the opening price has been falling. With the increase in new - grain supply, downstream demand is weak, and the futures may continue to be weak at the bottom around the National Day [7] Live Pigs - The live pig futures rebounded with position reduction at a low level, and the spot price was stable. The supply pressure is high in the second half of the year. Attention should be paid to the re - entry of secondary fattening and government policies. There is a plan to reduce production capacity by 1 million heads before the end of January next year. The current futures price is bearish [8] Eggs - Egg futures adjusted weakly, and the spot price was stable. The spot price may not rise significantly before the holidays and will be weak after the holidays. The industry needs to reduce production capacity. The pressure of newly - laid hens will decrease by the end of the year. A long position in the far - month contract for H1 next year can be considered [9]

New cotton sales may be favorable at the beginning of the new cotton listing period due to low old - crop inventory [2] - Xinjiang machine - picked cotton acquisition is expected to gradually start this week, with the acquisition price at 6.1 - 6.4 yuan/kg. The probability of a high - yield cotton crop in Xinjiang is large, but the specific yield estimate ranges from 720 to 770 tons [2] - Ginners are cautious about new cotton acquisition, and there is unlikely to be a situation of grabbing cotton. The domestic production - demand gap may narrow significantly due to the high yield [2] - At the beginning of the new cotton listing, the cost of new cotton strongly supports the futures price, but there is also hedging pressure. The weak demand in the peak season and poor spinning profits drag down the cotton price [2] - Positive signals have been released in Sino - US trade negotiations, but details need further follow - up. After Zhengzhou cotton broke through the support level, it is advisable to wait and see in the short term [2] Sugar - Overnight, US sugar fluctuated. In Brazil, although the sugarcane crushing volume and sugar yield decreased, the increase in the sugar - making ratio compensated for the loss of sugar production, and Brazil's sugar production will remain high [3] - Zhengzhou sugar fluctuated. In terms of production and sales, the sales rhythm this year is fast, and the spot pressure is relatively light [3] - The market's trading focus has shifted to the output estimate of the next sugar - making season. After July, the rainfall in Guangxi has been good, and the vegetation index of sugarcane has increased year - on - year. The sugar output in Guangxi in the 25/26 sugar - making season is expected to be relatively good [3] - Typhoon Koinu will bring wind and rain to Guangxi, with expected limited impact. Follow - up conditions need to be monitored [3] Apple - The futures price fluctuated strongly. In the spot market, the demand for cold - storage apples increased due to Mid - Autumn Festival stocking. For early - maturing apples, the supply of high - quality goods is scarce, and the purchase enthusiasm of merchants is high, with the pre - harvest order price remaining high [4] - Based on the bagging data, the apple production in the 25/26 quarter is expected to change little year - on - year, and there is no bullish driver on the supply side [4] - Apple farmers in Shaanxi are more bullish this year, and the amount of apples left for storage has increased. It is expected that the inventory in cold storage after the late - maturing apples are harvested in October will also increase, and the cold - storage inventory in the new quarter may be higher than market expectations [4] - Although the spot market performs well, funds believe that the cold - storage apple inventory in the new quarter will be higher than expected. It is expected that the futures price will continue to decline in the short term, and a bearish operation strategy is maintained [4] 20 - rubber, Natural Rubber & Synthetic Rubber - Today, RU, NR, and BR all rose slightly, and the sentiment in the futures market improved. The domestic spot price of natural rubber was stable, the spot price of synthetic rubber increased, and the port price of butadiene in the external market was stable [5] - The global natural rubber supply has entered the high - production period, and Super Typhoon Koinu passed through production areas such as China and Vietnam. Last week, the operating rate of domestic butadiene rubber plants continued to decline significantly, and some plants were shut down for maintenance or operating at low loads [5] - Last week, the operating rate of domestic tire plants increased slightly, tire enterprises maintained normal production, and the inventory of finished tire products increased [5] - This week, the total natural rubber inventory in Qingdao decreased to 46.12 tons, with the bonded - area inventory decreasing and the general - trade inventory increasing. Last week, the social inventory of Chinese butadiene rubber decreased to 1.26 tons, and the port inventory of Chinese butadiene continued to decline to 2.31 tons [5] - Overall, demand remains stable, the supply of natural rubber increases while inventory decreases, the supply of synthetic rubber decreases and inventory also decreases, and cost - driven factors strengthen. As the National Day holiday approaches, risk preference is cautious. It is advisable to wait and see and pay attention to typhoon weather [5] Pulp - Pulp futures fluctuated at a low level. The spot price of coniferous pulp was stable, and the price of broad - leaved pulp was also stable [6] - As of September 18, 2025, the inventory of mainstream pulp ports in China was 211.2 tons, a 5 - ton increase from the previous period, a 2.4% month - on - month increase, and the inventory was still at a high level year - on - year [6] - The digestion of warehouse receipts is slow, and the warehouse receipts of Russian coniferous pulp still suppress the near - month contracts. Attention should be paid to changes in warehouse receipts [6] - China's pulp imports in August 2025 were 265.3 tons, a 22.7 - ton month - on - month decrease. Currently, the port inventory in China is relatively high year - on - year, the pulp supply is relatively loose, and the pulp demand is still average. It is advisable to wait and see or adopt a range - trading strategy [6] Timber - The futures price fluctuated. In the spot market, the mainstream quotation was stable [7] - Last week, the arrival volume decreased month - on - month. In September, the quotation of New Zealand radiata pine decreased by $2 month - on - month, the domestic spot price remained weak, and the import willingness of traders decreased [7] - The external quotation is still high, the domestic spot price is difficult to improve, and the pressure on traders has increased. It is expected that imports will not increase significantly in the short term, and the domestic supply may remain at a low level [7] - Although the demand has entered the peak season, the port shipment volume decreased last week, indicating weak peak - season demand. However, the daily average shipment volume during the off - season remained above 60,000 cubic meters, and inventory reduction was smooth [7] - The total log inventory is low, and the inventory pressure is relatively small. Fundamentally, the supply - demand situation has improved, and the spot price is relatively low. However, the peak - season demand is average, and the short - term price increase momentum is insufficient. It is advisable to wait and see [7]

Report Investment Ratings - Crude oil: ★☆☆ (One star, indicating a bullish/bearish bias, with a driving force for price movement but limited trading opportunities on the market) [1] - Fuel oil: Not clearly defined in a comparable way [1] - Low-sulfur fuel oil: ★☆☆ (One star, indicating a bullish/bearish bias, with a driving force for price movement but limited trading opportunities on the market) [1] - Asphalt: ☆☆☆ (White star, indicating a relatively balanced short-term trend and poor trading opportunities, suggesting a wait-and-see approach) [1] - Liquefied petroleum gas: ☆☆☆ (White star, indicating a relatively balanced short-term trend and poor trading opportunities, suggesting a wait-and-see approach) [1] Core Views - The medium-term bearish trend in the crude oil market continues, with expected price drops for Brent and SC crude. However, geopolitical risks around the Iran nuclear negotiation and the Russia-Ukraine conflict may still intensify around the National Day holiday, so the strategy of combining high-level short positions with call options can be maintained [1]. - Fuel oil and low-sulfur fuel oil will mainly follow the weakening cost side due to the unchanged medium-term bearish trend in crude oil. Low-sulfur fuel oil faces supply pressure, while high-sulfur fuel oil may be relatively stronger and is susceptible to geopolitical news [2]. - The asphalt market maintains a tight supply-demand balance, with the BU contract having support below due to factors such as increased pre-holiday demand in the north, expected production increases, and inventory declines [2]. - The LPG market is expected to fluctuate at the bottom, with marginal improvements in supply and demand and expected better import costs [3]. Summary by Industry Crude Oil - Overnight international oil prices rebounded, with the SC11 contract rising 1.94% during the day. Iraqi Kurdish oil exports remain suspended, and there are discussions about a possible Russian diesel export ban. Negotiations between three European countries and Iran to avoid UN sanctions on September 27 have no clear progress [1]. - The medium-term bearish trend continues, with the expected average price of Brent crude dropping from $68 per barrel in Q3 to $63 per barrel, and the SC average price falling from 500 yuan per barrel to around 465 yuan per barrel [1]. Fuel Oil & Low-Sulfur Fuel Oil - Geopolitical factors affect supply expectations, causing a rebound in crude oil-related products. However, the unilateral trend of fuel oil will follow the weakening cost side [2]. - Low-sulfur fuel oil faces low加注 demand, increased domestic quotas, and overseas refinery RFCC accidents, intensifying supply pressure. High-sulfur fuel oil supply is expected to be loose in the medium term, but Russian refinery attacks may support supply expectations and make it relatively stronger [2]. Asphalt - The latest weekly shipment volume increased significantly compared to the previous period. The north has pre-holiday construction demand, while the south is affected by typhoon weather. Attention should be paid to the demand recovery rhythm [2]. - The initial production plans of refineries in October show a significant year-on-year increase but limited month-on-month growth. Factory inventories remain stable, and social inventories decreased by 57,000 tons, with the overall inventory level decreasing [2]. Liquefied Petroleum Gas - Crude oil rebounded, and LPG fluctuated. Refinery self-use of LPG increased, squeezing external supply, leading to a decline in commercial volume compared to last week [3]. - Typhoon weather in the South China region affects imports, while the import volume in East China increased but remains at a low level. Combustion demand is stable, and overall consumption increased slightly [3].
