Report Summary 1. Report Industry Investment Rating The report does not explicitly mention an overall industry investment rating. However, it provides specific views and strategies for glass and纯碱 (soda ash) separately: - **Glass**: Short - term: Oscillate weakly; Medium - term: Oscillate [2] - **Soda Ash**: Trend: Weakly [3] 2. Core Views - **Glass**: Short - term pressure comes from the unclear implementation of anti - deflation and anti - involution policies and the weak real - estate market. Although the policy factors are not clearly falsified, the demand is still not optimistic. The market is expected to be weakly oscillating in the short term and oscillating in the medium term [2]. - **Soda Ash**: The problems of high production and high inventory persist. Without large - scale production cuts or continuous improvement in the glass market, the price will be under pressure. The market is expected to be in an oscillating or weakly - priced state, depending on the actual situation of the glass industry and the implementation of anti - involution measures [3]. 3. Summary by Related Catalogs Glass - **Supply**: A 700 - ton/day production line in Dalian resumed ignition, with no water - draining or plate - guiding production lines. The weekly production remained stable. As of October 16, 2025, there were 296 glass production lines (200,000 tons/day) in China after excluding zombie lines, with 226 in production and 70 cold - repaired and shut down. The daily output was 161,300 tons, the same as on the 9th [2]. - **Demand**: As of October 15, 2025, the average order days of national deep - processing sample enterprises were 10.4 days, a 5.5% week - on - week decrease and a 21.2% year - on - year decrease. Some enterprises reported a decline in orders, and some were in a no - order state, while others had project orders that could last for 20 - 40 days. Enterprises with pre - stocked raw materials were mainly digesting their inventories [2]. - **Inventory**: As of October 16, 2025, the total inventory of national float - glass sample enterprises was 64.276 million heavy boxes, a 2.31% week - on - week increase and an 11.14% year - on - year increase. The inventory days were 27.3 days, an increase of 0.6 days from the previous period. Inventories in North China, East China, and Central China increased, while those in South China decreased slightly [2]. - **Price and Profit**: Recent spot transactions were poor, and prices in some regions decreased. The basis strengthened as futures prices fell more than spot prices. The profit for petroleum - coke fuel was about 91 yuan/ton, - 80 yuan/ton for natural - gas fuel, and 139 yuan/ton for coal fuel [15][20][23]. - **Inventory and Downstream开工率**: Recent spot transactions weakened, and the market mainly accumulated inventory. The impact of seasonal factors in the fourth quarter has weakened, but the inventory - reduction situation in the fourth quarter continues [31][34]. Photovoltaic Glass - **Price and Profit**: Recent market transactions began to weaken, and this situation is expected to continue. The mainstream order price of 2.0mm coated panels was about 13 yuan/square meter, and that of 3.2mm coated panels was about 20 yuan/square meter, both unchanged from the previous week [41][43]. - **Capacity and Inventory**: Market transactions weakened, and inventories in some regions began to rise. The sample inventory days were about 18.87 days, a 25.64% week - on - week increase [44][51]. Soda Ash - **Supply and Maintenance**: There were phased maintenance and production cuts in soda - ash enterprises. The production capacity utilization rate was 85%, down from 88.4% last week. The weekly output of heavy soda ash was about 415,500 tons. Some enterprises had maintenance plans, and the total maintenance volume in the fourth quarter was generally low [55][56]. - **Price and Profit**: The quotations of futures - cash merchants decreased by about 50 yuan/ton, and the low - end price in the Shahe area was 1,150 yuan/ton. Enterprise quotations changed little. The profit of the joint - alkali method in East China (excluding Shandong) was - 129 yuan/ton, and that of the ammonia - alkali method in North China was - 30 yuan/ton [72][77]. - **Inventory**: The total inventory of soda - ash manufacturers was about 1.7 million tons.

1. Report Industry Investment Rating There is no information provided in the report regarding the industry investment rating. 2. Core View of the Report - The risk appetite has declined, and the iron ore price has corrected from its high level. The supply - side disturbances of iron ore have been fully priced in the previous period. The market has now returned to trading the potential macro - negative impacts of Sino - US trade frictions. Coupled with the further erosion of industrial chain profits by the coking coal end, the relative strength of iron ore prices has weakened [3][5]. 3. Summary by Relevant Catalogs 3.1 Supply - **Overall Shipping Volume Data**: The global shipping volume in the recent week was 3207.5 million tons, a week - on - week decrease of 71.5 million tons and a year - on - year increase of 186.6 million tons. The cumulative shipping volume from the beginning of the year to the current period was 126,682.6 million tons, a year - on - year increase of 1.2%. The Australian shipping volume was 1854 million tons, a week - on - week decrease of 48.3 million tons and a year - on - year increase of 212.6 million tons.

FMG's shipping volume to China was 342.9 million tons, a week - on - week decrease of 22.3 million tons and a year - on - year decrease of 114 million tons. Vale's global shipping volume was 600.7 million tons, a week - on - week increase of 0.9 million tons and a year - on - year decrease of 54.2 million tons [4]. - **Supply - side Situation Analysis**: The recent shipping volume of mainstream iron ore has recovered to a year - on - year high, and freight rates have increased. In Q4, the shipping volume of Rio Tinto and Vale is still expected to increase. The shipping volume from Peru and Ukraine has not recovered yet, and the capacity utilization rate of domestic mines in the southwest region has not recovered [5][16][20][27]. 3.2 Demand - **Downstream Demand**: The hot metal production remains at a relatively high level, but its marginal impact on ore prices has weakened. The scrap steel price has risen and then fallen, and the price difference between scrap steel and hot metal has shrunk again [5][30][34]. 3.3 Market Performance - **Contract Performance**: The price of the main 01 contract fluctuated weakly, closing at 771.0 yuan/ton. The open interest was 545,000 lots, an increase of 69,200 lots. The average daily trading volume was 369,000 lots, a week - on - week increase of 136,000 lots [7]. - **Spot Price Performance**: The spot price has fallen from its high level following the futures market. For example, the price of Carajás fines (64.5%) in Qingdao Port decreased from 923 yuan/ton last week to 901 yuan/ton this week [11]. 3.4 Inventory - The port inventory shows a seasonal accumulation trend in Q4 [38][40]. 3.5 Downstream Profit - The downstream industry has a high operating rate, but the profit has been continuously declining [42]. 3.6 Spot Category Price Difference - This week, the high - grade Carajás fines have corrected significantly, and the price difference between Carajás fines and PB fines has weakened. The price of domestic iron ore concentrate is still relatively strong compared to imported PB fines [45]. 3.7 Futures Monthly Spread - The valuation of the calendar spread for the bull spread is relatively high year - on - year. Recently, attention can be paid to the opportunity of spread narrowing caused by the macro - risk appetite correction [51]. 3.8 Basis Performance - This week, the futures price has fallen rapidly from its high level, and the basis has increased significantly [53].

Group 1: Industry Investment Rating - No relevant content found Group 2: Core Views - The fundamentals of Shanghai nickel show a fierce game between smelting - end inventory accumulation and the Indonesian nickel ore logic, with contradictions still accumulating. In the short - term, it's difficult to break through the narrow - range pattern, while long - term volatility is expected to increase. The core support lies in the cost of the pyrometallurgical path and the uncertainty of the Indonesian nickel ore supply governance policy [2]. - The fundamentals of stainless steel make it difficult to find an upward driving force, but the downward space is limited. The market may marginally stabilize and fluctuate. The long - term and short - term, as well as reality and expectation, are involved in the long - short game [3]. Group 3: Summary by Related Catalogs Nickel Fundamental Analysis - **Supply - demand situation**: The smelting end has returned to steep inventory accumulation, with the surplus concentrated in the refined nickel segment. The marginal supply of refined nickel increases while demand is weak, and the expected new production of pure nickel in the second half of the year exerts pressure. Although the fundamentals of non - standard nickel have marginally improved, the conversion of refined nickel production has not effectively alleviated the inventory accumulation contradiction of refined nickel [2]. - **Supporting factors**: The uncertainties in the cost of the pyrometallurgical path and the Indonesian nickel ore supply governance policy support the price. For example, some areas of the WBN park were taken over due to violations of forestry license regulations, and mines failing to pay reclamation deposits were ordered to suspend production. The Indonesian government also urged enterprises to resubmit the 2026 RKAB budget online, which may lead to increased market inventory and support the nickel ore price [2]. Stainless Steel Fundamental Analysis - **Demand side**: The overdraft effect of early export rush has been basically digested, but demand is still suppressed by the resonance of tariff barriers and weak real - estate post - cycle consumption. The cumulative year - on - year growth rate of apparent demand is only half of the previous year, 2.6% [3]. - **Supply side**: The supply growth rate has declined compared with previous years but has a marginal increase. The production plan for October is 3.45 million tons, a month - on - month increase of 3% and a cumulative year - on - year increase of 3.0%. The 300 - series is about 1.77 million tons, with a cumulative year - on - year/month - on - month increase of 4.2%/3.5%. The total supply (including imports) cumulative growth rate is expected to be 1.8% [3]. - **Supply - demand balance**: The cumulative surplus (inventory accumulation) has converged compared with previous years. In the long - term, the stainless - steel industry may shift from a one - sided valuation - reduction logic of strong supply and weak demand to a bottom - seeking thinking of both weak supply and demand. In the short - term, there is no upward driving force in the fundamentals, but the cost limits the downward space [3]. Inventory Tracking - **Refined nickel**: On October 17, China's refined nickel social inventory increased by 1,875 tons to 47,505 tons. Among them, the warehouse receipt inventory increased by 1,814 tons to 27,042 tons, the spot inventory increased by 261 tons to 16,573 tons, and the bonded - area inventory decreased by 200 tons to 3,890 tons. LME nickel inventory increased by 13,152 tons to 250,530 tons [6]. - **New energy**: On October 17, the inventory days of SMM nickel sulfate's upstream, downstream, and integrated production lines changed by - 1, - 1, + 1 month - on - month to 4, 8, 7 days respectively; the precursor inventory on October 17 changed by - 1 month - on - month to 13.0 days; the ternary material inventory on October 9 remained unchanged month - on - month at 7.1 days [6]. - **Nickel - iron and stainless steel**: On October 15, the SMM nickel - iron inventory was 29,062 tons, with a stable and slightly increasing month - on - month trend and a year - on - year increase of 41%. In September, the SMM stainless - steel mill inventory was 1.532 million tons, a year - on - month/month - on - month increase/decrease of 4%/ - 1%. On October 16, the Mysteel stainless - steel social inventory was 1.0412 million tons, a week - on - week decrease of 1.18%, and the 300 - series inventory was 655,200 tons, a week - on - week increase of 1.02% [6]. Market News - **Indonesian mining sanctions**: Due to violations of forestry license regulations, the Indonesian forestry working group took over a 148 - hectare mining area of PT WedaBav Nickel. The Indonesian government also imposed sanctions on 190 mining companies for failing to provide claim and refund guarantees [7][8]. - **Policy regulations**: The Indonesian Ministry of Energy and Mineral Resources issued a ministerial order regarding the preparation, submission, and approval procedures of the mining RKAB and the reporting procedures for activity implementation. The approval plan for the next - year's RKAB is expected to be completed by November 15 this year [9]. - **Trade news**: China suspended an unofficial subsidy for imported copper and nickel from Russia. Trump claimed to impose an additional 100% tariff on China from November 1 and implement export controls on "all key software" [8][9]. Weekly Key Data Tracking - **Futures prices**: The closing price of the Shanghai nickel main contract was 121,160, and that of the stainless - steel main contract was 12,630. There were also corresponding price changes compared with previous periods [11]. - **Trading volume**: The trading volume of the Shanghai nickel main contract was 76,335, and that of the stainless - steel main contract was 147,948, with different volume changes compared with previous periods [11]. - **Industrial chain data**: Data such as the price of 1 imported nickel, Russian nickel premium, nickel bean premium, and various product spreads and import profits were provided, showing different trends compared with previous periods [11].
