1. Report Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoints of the Report - The energy and chemical futures market as a whole continues to consolidate in a volatile pattern. The supply pressure in the crude oil market persists, and attention should be paid to geopolitical risks. The prices of various energy and chemical products show different trends, with some being volatile, some weakly volatile, and some expected to experience short - term fluctuations [2][3][4]. 3. Summary According to Relevant Catalogs 3.1 Market Situation and Logic of Energy and Chemical Products - **Crude Oil**: Supply pressure persists, and geopolitical risks are the focus. The freight rate of VLCC from the Middle East to Asia has reached a two - and - a - half - year high. The持仓 of Brent crude oil has reached a record high, indicating a large divergence between long and short positions. The disruption of Ukraine to Russia's oil product exports remains unresolved [2][10]. - **Asphalt**: The futures price fluctuates below 3500 yuan/ton. Saudi Arabia promotes OPEC+ to continue increasing production, and the geopolitical situation in the Middle East escalates. The supply tension problem has been significantly alleviated, and the pricing power of asphalt futures prices is expected to return to Shandong. The hidden inventory in South China is a concern [11]. - **High - Sulfur Fuel Oil**: The price shows a weak and volatile trend. Saudi Arabia promotes OPEC+ to continue increasing production, and the geopolitical situation in the Middle East escalates. The export of Russian fuel oil reaches a record high, and the demand expectation deteriorates [11]. - **Low - Sulfur Fuel Oil**: It fluctuates following crude oil. It is affected by factors such as the decline in shipping demand, green energy substitution, and high - sulfur substitution. The supply is expected to increase, and the demand is expected to decline [13]. - **PX**: The cost support is insufficient, and the processing fee is under pressure. The supply is expected to increase, and the demand from downstream PTA is expected to weaken [14]. - **PTA**: New device commissioning is postponed, and maintenance is implemented, but the market boost effect is limited. The processing fee is expected to be repaired, and attention should be paid to the support around 4600 yuan/ton [14]. - **Pure Benzene**: The price falls intraday due to the realization of macro - benefits and the decline in commodity sentiment. The price is expected to fluctuate narrowly in the short term, and attention should be paid to the change in crude oil prices and the subsequent import volume of pure benzene [14][15][16]. - **Styrene**: The price resumes falling due to the decline in commodity sentiment. The inventory pressure is large in September - October, and the cost - end pure benzene inventory accumulation pressure may drag down the valuation. There may be a small rebound in the short term, but the amplitude is limited by inventory [16][17]. - **Ethylene Glycol (MEG)**: The market sentiment is under pressure due to the expectation of weakening supply and demand. The price is expected to fluctuate in a low - level range, and attention should be paid to the support around 4200 yuan/ton [17][18][19]. - **Polyester Staple Fiber**: The inventory is slightly reduced, and the processing fee is firm. The supply and demand pattern is relatively healthy, and the absolute value follows the raw material fluctuations and fluctuates in the short term [20][21][22]. - **Polyester Bottle Chips**: The driving force is limited, and it follows passively. The price follows the upstream fluctuations, and the absolute value follows the raw material fluctuations and fluctuates [22][24]. - **Methanol**: The port trading volume increases slightly, and the futures price fluctuates and declines. The port inventory pressure is large, and the inland inventory pressure is limited. There may be low - buying opportunities from September to October [25]. - **Urea**: Under the condition of loose supply and demand, the downstream conducts price negotiations, and the futures price fluctuates and consolidates in the short term [25]. - **LLDPE (Plastic)**: The maintenance rate declines, and there is still restocking demand before the festival. The price fluctuates. The macro - support weakens, the oil price fluctuates weakly, and the demand may have certain support [28]. - **PP**: The spot price is at a low level, and there is still restocking demand before the festival. The price fluctuates and declines. The supply side still has an increasing trend, and the inventory pressure in the upper and middle reaches exists [29][30]. - **PL**: It fluctuates following PP, and the price fluctuates and declines in the short term [30]. - **PVC**: It operates in a volatile manner with weak reality and strong expectation. The macro - sentiment is warm, but the fundamental pressure is large, and the cost moves up slightly [33]. - **Caustic Soda**: The spot price decline space is limited, and the futures price fluctuates. The fundamental pressure gradually appears, but the restocking before the National Day may provide certain support [33]. 3.2 Monitoring of Energy and Chemical Indicators - **Inter - period Spread**: Different energy and chemical products show different inter - period spread values and changes. For example, the M1 - M2 spread of Brent is 0.5 yuan/ton with a change of 0.01 yuan/ton, and the 1 - 5 - month spread of PX is 0 yuan with a change of - 8 yuan/ton [36]. - **Basis and Warehouse Receipts**: The basis and warehouse receipt quantities of various products also vary. For example, the basis of asphalt is 93 yuan/ton with a change of 18 yuan/ton, and the warehouse receipt is 65010 [37]. - **Inter - product Spread**: The inter - product spreads of different energy and chemical products have different values and changes. For example, the 1 - month PP - 3MA spread is - 112 yuan/ton with a change of 34 yuan/ton [39]. 3.3 Commodity Index - On September 18, 2025, the comprehensive index of commodities is 2224.80, down 0.94%; the commodity 20 index is 2489.53, down 1.04%; the industrial products index is 2246.67, down 1.06%. The energy index on September 18, 2025, has a daily decline of 1.27%, a 5 - day increase of 2.98%, a 1 - month increase of 0.64%, and a year - to - date decline of 0.86% [281][283].

Steel Industry - The supply-demand contradiction in the steel market is strengthening, making it easier for prices to rise than to fall. The demand is gradually recovering as the peak season approaches, with high demand for plate steel and a low recovery in rebar demand. On the supply side, steel mills are facing narrowing profits, leading to a decrease in overall supply. Plate steel supply remains high, while rebar production has significantly decreased, alleviating supply pressure. Overall, with the arrival of the peak demand season and stricter implementation of industrial policies, the supply-demand contradiction and cost support for steel are expected to gradually strengthen. Short-term steel prices are anticipated to continue a trend of fluctuating increases [1][2]. Iron Ore - The expectations for supply and demand are improving, enhancing price support for iron ore. Steel mills are gradually resuming production, leading to a recovery in iron ore demand. On the supply side, overseas mine shipments have significantly increased, resulting in a moderate growth in overall supply. Iron ore inventories are stabilizing at low levels, indicating minimal inventory pressure. Overall, with the continuous warming of macro policy expectations and the recovery of downstream demand, the outlook for iron ore supply and demand is expected to continue improving, with prices likely to maintain a trend of fluctuating increases [1][2]. Coking Coal - The capacity utilization rate of 523 coking coal mines has increased by 1.9% to 84.7%, with daily raw coal output reaching 1.9 million tons, a month-on-month increase of 44,000 tons. The demand side shows strong rigid support, driven by increased washing plant operating rates and a rebound in iron water production. However, the market is still focused on "anti-involution," and the space for further increases in coal mine operating rates is limited due to strong safety supervision policies. Overall, the coking coal supply-demand structure may be optimized, maintaining a trend of fluctuating strength [2]. Shipping Industry - The European shipping index is currently showing a weak trend. On the spot market, major shipping companies are continuously lowering their quotes, with the average price for a large container around $1,650, indicating a slight discount to the market. The supply-demand imbalance is prominent, with demand entering a low season and a lack of new shipping volume. The average weekly capacity in September has increased by 16% year-on-year, but the scale of empty classes in October is not sufficient to alleviate the oversupply situation. The market sentiment remains pessimistic, and the index is expected to continue running weakly in the short term [3]. Methanol - Methanol futures prices have continued to decline. Domestic methanol capacity utilization and output have unexpectedly decreased this week. However, the operating rates of traditional demand products have mostly increased, with significant recoveries in DME and MTBE. The market is expected to maintain a trend of inventory reduction due to pre-holiday stocking and upstream companies actively reducing inventory to avoid accumulation risks during the holiday. Overall, the methanol market is expected to continue a downward trend in the short term, with some support from supply-side reductions and recovering downstream operating rates [4]. Urea - Urea prices have shown a downward trend this week, with capacity utilization and weekly output increasing. The upcoming recovery in production is expected to exceed maintenance, leading to a significant increase in daily output. However, domestic urea demand remains tepid, and the overall supply-demand imbalance persists, with companies facing challenges related to inventory and costs. Without policy changes, urea futures prices are likely to continue fluctuating downward in the short term [4]. Soda Ash & Glass - Soda ash and glass prices are experiencing a downward trend. The overall supply of soda ash is decreasing slightly, with a capacity utilization rate of 85.53%. The weekly output has dropped by 1.54 million tons. The glass market is stable, but demand is insufficient, leading to a gradual decline in production and sales. The overall supply pressure for soda ash remains high, and prices are expected to continue fluctuating weakly [5]. Asphalt - Asphalt prices are showing a weak trend, influenced by the end of the traditional fuel consumption season in the U.S. and ongoing OPEC+ production increases. However, the inventory of asphalt plants and social stocks continues to decline, which may positively impact prices. The upcoming National Day holiday is expected to drive demand, particularly in northern regions, while southern regions face supply pressures [6][7]. Caustic Soda - Caustic soda prices are experiencing a downward trend, with average capacity utilization at 81.9%. The inventory of liquid caustic soda has increased, and demand from downstream aluminum oxide enterprises remains stable. Overall, the caustic soda market is expected to continue fluctuating weakly due to increased supply and limited demand [8]. Polyolefins - Polyolefin prices are declining, with limited demand from downstream sectors. Despite some replenishment activities, the overall purchasing momentum remains insufficient. The supply side is increasing due to more operational facilities, leading to a rise in inventory levels. The market sentiment is cautious, and prices are expected to continue fluctuating downward [9]. Polyester - The polyester market is stable, with supply and demand remaining balanced. The operating rates of PTA and downstream polyester production have increased slightly, but overall demand remains below expectations. The inventory levels of PTA are at historical lows, indicating a tight supply situation. Prices are expected to fluctuate based on cost movements [10][11]. Nonferrous Metals - The copper market is influenced by the recent Fed rate cut, with domestic supply tightening due to maintenance at smelting plants. The market is closely monitoring consumption patterns leading up to the National Day holiday, with expectations of increased purchasing from large enterprises [14]. Agricultural Products - The oilseed market is under pressure due to high domestic soybean inventories and slow demand recovery. The cotton market is experiencing price pressure from low demand and high import levels, while the sugar market is facing downward pressure from increased production in India and Brazil [18][19]. Rubber - The rubber market is experiencing a weak trend, with increased imports and stable production levels. The demand from processing plants remains strong, but overall market sentiment is affected by macroeconomic factors [22][23].

Report Industry Investment Rating No relevant information provided. Core View of the Report The Fed's monetary policy adjustments and industry - specific factors jointly affect the prices of various non - ferrous metals. Overall, most non - ferrous metals show different trends in price, inventory, and market sentiment, with short - term price trends varying from metal to metal [2][4][5]. Summary by Metal Copper - The Fed's interest rate cut and the rate dot - plot's indication of future cuts led to copper price adjustments. LME copper closed down 1.41% to $9974/ton, and SHFE copper closed at 79880 yuan/ton. LME copper inventory decreased, and the domestic downstream procurement sentiment was weak. Short - term copper prices may turn to a volatile trend, with the SHFE copper main contract running between 79200 - 80800 yuan/ton and LME copper 3M between 9880 - 10100 dollars/ton [2]. Aluminum - After the Fed's interest rate cut, aluminum prices generally declined. LME aluminum closed down 0.83% to $2689/ton, and SHFE aluminum closed at 20750 yuan/ton. Domestic inventories increased, and the market transaction was not ideal. With downstream entering the traditional peak season, aluminum prices are expected to be strongly supported. The domestic main contract is expected to run between 20700 - 21000 yuan/ton, and LME aluminum 3M between 2660 - 2720 dollars/ton [4]. Lead - Lead prices are expected to be strong in the short term. Lead concentrate raw materials are in short supply, and the downstream battery inventory is decreasing. Although there was some emotional disturbance in the non - ferrous metal sector before the Fed's interest rate meeting, the overall sentiment is still positive, and the improved industry data supports the upward breakthrough of lead prices [5]. Zinc - Zinc prices are expected to be strong in the short term. Zinc concentrate inventory is rising, and processing fees are differentiated. The import window is closed, and the zinc ore surplus is alleviated. Although the SHFE zinc increase is limited, if the zinc ingot export window opens and zinc ore imports are restricted, the domestic zinc price may rise with the sector [6]. Tin - Tin prices are expected to be strongly volatile. The supply of tin is significantly reduced due to slow resumption of production in Myanmar and smelter maintenance. Although the traditional consumer electronics and home appliance sectors have weak demand, the demand has marginally improved with the arrival of the peak season, so the price is expected to be strong [7]. Nickel - In the short term, the high inventory of refined nickel drags down the nickel price, but in the long term, factors such as the Fed's easing expectations and the RKAB approval are expected to support the nickel price. It is recommended to buy on dips, with the SHFE nickel main contract running between 115000 - 128000 yuan/ton and LME nickel 3M between 14500 - 16500 dollars/ton [9]. Lithium Carbonate - The price of lithium carbonate is in a volatile adjustment. The fundamental improvement has been reflected in the market, and there is currently no new marginal change to drive the price up. Attention should be paid to industry information and macro - expectation changes. The reference operating range of the GZFE lithium carbonate 2511 contract is 70800 - 75800 yuan/ton [12]. Alumina - In the short term, it is recommended to wait and see. Although the ore price has short - term support, it may be under pressure after the rainy season, and the over - capacity pattern in the smelting end is difficult to change in the short term. However, the Fed's interest rate cut expectation may drive the non - ferrous metal sector to be strong. The domestic main contract AO2601 is expected to run between 2800 - 3100 yuan/ton [14]. Stainless Steel - The demand for stainless steel is weak due to the downturn in the real estate industry. Although the demand from the new energy vehicle industry is increasing, it cannot offset the decline in traditional demand. The downstream consumption has not improved significantly, and the market is waiting and watching [16][17]. Cast Aluminum Alloy - Cast aluminum alloy prices are expected to remain high in the short term. The downstream is transitioning from the off - season to the peak season, and the cost is strongly supported by the supply disturbance of scrap aluminum at home and abroad. With the exchange reducing the margin ratio, market activity is increasing [19].

Report Industry Investment Rating No information provided in the given content. Core Viewpoints - The overall atmosphere in the commodity market has warmed up, but the prices of finished products are showing a volatile and slightly stronger trend. The economic data in August slowed down and were lower than expected, increasing the possibility of more stimulus policies. The real - estate sales are still weak, and it will take time for the real - estate market to stabilize. The export volume decreased slightly last week and remains in a weak and volatile pattern. The demand for rebar is weak, while the demand for hot - rolled coils is relatively firm, and the trends of rebar and hot - rolled coils have diverged. Steel mills' profits are gradually narrowing, and the weak characteristics of the market are becoming more prominent. If the subsequent demand cannot be effectively repaired, steel prices still have the risk of decline. The raw material prices are relatively firm, and continuous attention should be paid to the possible disturbances caused by domestic and overseas macro - policies [3]. - The short - term iron ore price is expected to fluctuate. The overseas iron ore shipments have rebounded to the same - period high, the proximal arrival volume has decreased slightly, and the short - term demand support still exists. The steel mill profitability rate continues to decline, and the port and steel mill inventories have both increased slightly. The terminal data shows that the apparent demand for the five major steel products has increased to some extent, and the inventory accumulation speed has slowed down. The rebar data is weak, and the difference between hot - rolled coils and rebar has been strong recently. Attention should be paid to whether the internal contradictions of finished products will be transmitted to the raw material end [6]. - For manganese silicon and ferrosilicon, the prices of their main contracts fluctuated higher on September 17. From a disk perspective, they are in a range - bound pattern. The fundamentals of manganese silicon are not ideal, mainly due to high - level supply and weak demand in the building materials sector. Ferrosilicon has no obvious contradictions and drivers in its supply - demand fundamentals. Both are likely to follow the trend of the black - sector market, and their operational cost - effectiveness is relatively low [8][9][11]. - The price of industrial silicon fluctuated and strengthened. The fundamentals of over - capacity, high inventory, and insufficient effective demand have not changed fundamentally. The short - term valuation is neutral. If the market continues to discuss topics such as "anti - involution", the price may rise further under the expected drive; otherwise, the weak fundamentals will limit the price increase. The price of polysilicon is more influenced by policy narratives. Before the actual progress of capacity integration, the disk price is prone to fluctuate with the ebb and flow of sentiment [13][14][16]. - For glass, the industry supply has increased slightly, and the enterprise inventory has decreased. The pre - holiday stocking has promoted inventory reduction, but the market supply is still abundant, and the terminal demand is weak. It is recommended to be cautiously bullish. For soda ash, the industry supply has contracted slightly, mainly due to the maintenance of production lines. Some downstream enterprises have pre - holiday stocking needs, but most are still purchasing based on rigid demand. The market trading atmosphere is tepid, and it is expected to fluctuate within a narrow range [18][19]. - Although the black - sector prices still have the risk of short - term phased decline under the influence of real - demand, in the face of the subsequent certainty of overseas fiscal and monetary easing, and the opening of China's policy space after the US enters the interest - rate cut cycle, the black - sector may gradually have the cost - effectiveness of long - allocation in the future, and the key node may focus on the "Fourth Plenary Session" around mid - October [10].

Report Industry Investment Rating - No relevant information provided Core Viewpoints - This week, the reduction in supply is gradually becoming evident. After the price cuts of butadiene and cis - butadiene rubber, the spot offers are gradually declining, which may prompt some downstream enterprises to start stocking up. As a result, the inventories of producers and traders may slightly decrease [2]. - Last week, the capacity utilization rate of domestic tire enterprises increased significantly, and most enterprises that had maintenance at the beginning of the month have returned to normal levels. It is expected that most enterprises will maintain their current production schedules this week to build up inventory for the "National Day" holiday and fill the gaps in previous orders. The overall capacity utilization rate is expected to fluctuate slightly [2]. - The BR2511 contract is expected to fluctuate in the range of 11,500 - 12,000 in the short - term [2].

Group 1: Overall Report Information - The report is a non - ferrous metals morning report released on September 17, 2025, by the non - ferrous metals team of the research center [1] Group 2: Copper - **Price and Inventory Data**: From September 10 - 16, 2025, the spot premium of Shanghai copper increased by 25, the spread between scrap and refined copper increased by 257, and the inventory of the Shanghai Futures Exchange increased by 3049. The LME inventory decreased by 1675 [1] - **Core View**: This week, copper prices fluctuated widely around 80,000, breaking upward on Thursday and Friday. Fundamentally, the domestic social inventory of copper did not accumulate despite the increase in imported copper arrivals. The downstream start - up weakened, and it was in the stage of consuming finished product inventory. Macroscopically, copper currently benefits from the global fiscal and monetary double - expansion. After the FOMC meeting next week, pay attention to the possible phased realization of bullish factors. The copper price is expected to be easy to rise and difficult to fall in the third and fourth quarters. If there is a callback after short - term bullish factors are realized, consider laying out medium - term long positions below 79,500 or selling put options below 78,000 [1] Group 3: Aluminum - **Price and Inventory Data**: From September 10 - 16, 2025, the price of Shanghai aluminum ingots remained unchanged, the domestic alumina price decreased by 9, and the aluminum exchange inventory remained unchanged. The aluminum LME inventory decreased by 1500 [1] - **Core View**: Supply increased slightly, with imports of aluminum ingots providing an increment from January to July. Downstream start - up improved, but overseas demand declined significantly. In September, inventory is expected to decline. In the short - term, the fundamentals are okay. Pay attention to demand. Hold at low prices in the low - inventory pattern and pay attention to inter - month and internal - external reverse arbitrage [1] Group 4: Zinc - **Price and Inventory Data**: From September 10 - 16, 2025, the spot premium remained at - 60, the price of Shanghai zinc ingots increased by 30, and the zinc social inventory remained unchanged. The LME zinc inventory decreased by 1175 [1][2] - **Core View**: This week, zinc prices fluctuated narrowly. On the supply side, the domestic TC decreased slightly, and the imported TC increased. In September, smelting production decreased slightly due to concentrated maintenance. On the demand side, domestic demand was seasonally weak, and overseas demand had some production resistance. The domestic social inventory continued to rise, and the overseas LME inventory decreased. The current pattern of strong overseas and weak domestic may further differentiate. In the short - term, it can be used as a short - side configuration, and the internal - external positive arbitrage can be continued to hold [2] Group 5: Nickel - **Price and Inventory Data**: From September 10 - 16, 2025, the price of 1.5% Philippine nickel ore remained unchanged, the price of Shanghai nickel spot increased by 50, and the LME inventory increased by 1950 [3] - **Core View**: On the supply side, the production of pure nickel remained at a high level. On the demand side, it was weak overall, and the premium was stable recently. In terms of inventory, there was a slight accumulation in the domestic market and an increase in overseas warehouse receipts. In the short - term, the fundamentals are weak, and the anti - involution sentiment in the macro - aspect has rebounded. Pay attention to the news that the Indonesian Forestry Bureau has taken over part of the world's largest nickel mine [4] Group 6: Stainless Steel - **Price and Inventory Data**: From September 10 - 16, 2025, the price of 304 cold - rolled coils increased by 50, and the price of 201 cold - rolled coils increased by 50 [5][6] - **Core View**: On the supply side, steel mills in the north are expected to resume production gradually. On the demand side, it is mainly for rigid demand. In terms of cost, the price of nickel iron remained stable, and the price of ferrochrome increased slightly. In terms of inventory, the inventory in Xijiao and Foshan remained stable, and the warehouse receipts decreased slightly. Fundamentally, it is still weak. Pay attention to the news that the Indonesian Forestry Bureau has taken over part of the world's largest nickel mine [6] Group 7: Lead - **Price and Inventory Data**: From September 10 - 16, 2025, the spot premium decreased by 5, the Shanghai - Henan price difference decreased by 25, and the LME inventory increased by 2225 [7] - **Core View**: This week, lead prices rose due to macro - factors. On the supply side, the scrap volume was weak year - on - year, and the supply of waste batteries was tight. On the demand side, the inventory of battery finished products was high, and the market was not prosperous in the peak season. The supply is expected to be tight, and the LME registered warehouse receipts decreased by 10,000. In September, there is an expectation of a peak season, but the terminal consumption and lead ingot procurement are weak this week. It is expected that lead prices will fluctuate significantly next week, in the range of 16,800 - 17,200 [7] Group 8: Tin - **Price and Inventory Data**: From September 10 - 16, 2025, the spot import earnings decreased by 2200.06, the spot export earnings increased by 1949.49, and the LME inventory remained unchanged [9] - **Core View**: This week, tin prices fluctuated widely. On the supply side, the processing fee of tin ore was at a low level, and some domestic smelters reduced production. Overseas, the import from Wa State was less than 200 metal tons in August, and the supply of raw materials is expected to increase gradually after October. On the demand side, the elasticity of solder is limited, and the domestic inventory fluctuates. The LME inventory has rebounded from a low level. In the short - term, the domestic fundamentals are in a situation of weak supply and demand. It is recommended to wait and see in the short - term and hold at low prices close to the cost line in the long - term [9] Group 9: Industrial Silicon - **Price and Inventory Data**: From September 10 - 16, 2025, the 421 Yunnan basis decreased by 15, the 421 Sichuan basis decreased by 65, and the number of warehouse receipts decreased by 33 [10] - **Core View**: This week, the leading enterprises in Xinjiang continued to resume production. Currently, the production in Sichuan and Yunnan is stable. In the short - term, the supply and demand in September and October are still in a tight balance state. In the long - term, the over - capacity of industrial silicon is still large, and the price is expected to fluctuate at the bottom of the cycle based on the seasonal marginal cost [10] Group 10: Lithium Carbonate - **Price and Inventory Data**: From September 10 - 16, 2025, the SMM electric carbon price increased by 400, the SMM industrial carbon price increased by 400, and the number of warehouse receipts decreased by 139 [12] - **Core View**: This week, lithium carbonate prices fluctuated widely. Affected by the expectation of CATL's resumption of production, the futures price dropped significantly in the middle of the week. On the raw material side, miners are not willing to sell at low prices. On the lithium salt side, upstream salt factories also have the sentiment of holding prices. The current basis level has strengthened slightly, and the supply of large - discount goods has decreased. The current contradiction is that under the background of over - capacity, the resource side faces phased compliance disturbances. In the seasonal peak season, the monthly balance after CATL's gradual production reduction turns to continuous inventory reduction, but the amplitude is small. The price elasticity is high after the speculation of supply - side disturbances is realized, and the price has strong downward support before the disturbances are realized [12]
