Group 1: Rubber Industry Report Industry Investment Rating Not provided Core Viewpoint The fundamentals of natural rubber (NR) have not changed significantly. There is still cost support from the upstream, while downstream players are resistant to high - priced raw materials. The reference range for the 01 contract is 15,000 - 16,500. Follow - up attention should be paid to the raw material output during the peak season in the main production areas and whether the La Nina phenomenon affects the supply. If the raw material supply is smooth, consider short - selling at high levels; if the supply is not smooth, the rubber price is expected to remain high [1]. Summary by Directory - **Spot Prices and Basis**: On September 11, the price of Yunnan state - owned whole - miscible rubber (SCRWF) in Shanghai was 14,900 yuan/ton, down 150 yuan/ton or 1.00% from the previous day. The price of Thai standard mixed rubber remained unchanged at 15,000 yuan/ton. The basis of some varieties showed significant changes, such as the basis of Panjingxing, which decreased by 8.06% [1]. - **Inter - month Spreads**: The 9 - 1 spread was - 82 yuan/ton, down 0.51% from the previous day; the 1 - 5 spread was - 35 yuan/ton, up 22.22% [1]. - **Fundamentals**: In July, the production of Thailand, Indonesia, and India showed different trends, with Thailand's production increasing by 1.61%, Indonesia's by 12.09%, and India's decreasing by 2.17%. China's production decreased by 1.30%. The weekly开工率 of semi - steel and all - steel tires increased. The domestic tire production in July decreased by 8.16%, while the tire export volume increased by 10.51%. The total import volume of natural rubber in July increased by 2.47% [1]. - **Inventory Changes**: The bonded area inventory decreased by 0.64%. The factory - warehouse futures inventory of natural rubber on the SHFE increased by 1.99%. The出库率 of warehouses increased due to downstream holiday stocking, and there is still an expectation of further inventory reduction [1]. Group 2: Log Industry Report Industry Investment Rating Not provided Core Viewpoint Currently, logs are in a volatile pattern. The spot market continues to weaken, and the enthusiasm of traders for imports has declined. The arrival volume remains low, and it is expected that the supply in September will continue to be at a low level. The inventory is low and has been decreasing for several consecutive weeks. The demand remains above 60,000 cubic meters but has not shown an obvious improvement trend. After entering the seasonal peak season, observe whether the shipment volume improves significantly. Currently, the valuation of the futures market is relatively low, and it is in a stage of volatile bottom - seeking. It is recommended to go long at low levels [3]. Summary by Directory - **Futures and Spot Prices**: On September 11, the 2511 log contract closed at 804.5 yuan/cubic meter, down 2 yuan/cubic meter from the previous day. The spot prices of major benchmark delivery products remained unchanged. The new round of FOB quotes has loosened to the range of 114 US dollars/JAS cubic meter [3]. - **Supply**: Last week, the total arrival volume at 12 ports was about 170,000 cubic meters, a record low for the year. This week, 11 ships of New Zealand logs are expected to arrive at 12 ports in China, an increase of 6 ships from last week, and the total arrival volume is about 402,000 cubic meters, a week - on - week increase of 136% [3]. - **Demand**: The shipment volume last week decreased slightly but remained above 60,000 cubic meters. As of September 5, the average daily shipment volume of logs was 61,200 cubic meters [3]. Group 3: Industrial Silicon Industry Report Industry Investment Rating Not provided Core Viewpoint From the cost side, raw material prices are rising, and the electricity price in the southwest region will gradually increase during the dry season, which will lift the cost center of industrial silicon. Although the current production of industrial silicon has increased month - on - month, there are also news of capacity clearance, and small furnaces may be shut down. From the supply - demand side, both supply and demand increased in August, maintaining a tight balance. If some capacity is cleared in the long - term, the supply pressure will be reduced. It is recommended to go long at low levels, but also pay attention to the inventory and warehouse receipts while production increases. The main price fluctuation range is expected to be 8,000 - 9,500 yuan/ton [4]. Summary by Directory - **Spot Prices and Basis**: On September 11, the price of East China SI4210 industrial silicon was 9,500 yuan/ton, up 100 yuan/ton or 1.06% from the previous day. The basis of some varieties showed significant changes, such as the basis of SI4210, which increased by 38.46% [4]. - **Inter - month Spreads**: The 2509 - 2510 spread decreased by 5032.35% [4]. - **Fundamentals**: The national industrial silicon production in the current period was 385,700 tons, an increase of 14.01% from the previous period. The production in Xinjiang, Yunnan, and Sichuan all increased. The production of organic silicon DMC increased by 11.66%, while the production of recycled aluminum alloy decreased by 1.60%. The industrial silicon export volume increased by 8.32% [4]. - **Inventory Changes**: The social inventory increased by 0.37%, and the order - form inventory increased by 0.10% [4]. Group 4: Polysilicon Industry Report Industry Investment Rating Not provided Core Viewpoint In September, although there is some production reduction on the supply side, there are also factories resuming production to make up for the supply, so the overall supply reduction is not obvious. The silicon wafer production plan has increased slightly month - on - month, and the supply - demand situation in September may show a slight inventory accumulation pattern. Since late August, downstream players have carried out obvious inventory replenishment, and the price increase of polysilicon has been gradually accepted by the downstream, with a smooth spot price transmission mechanism. In the follow - up, the futures market pays less attention to the fundamentals and more to policy expectations. Short - term price fluctuations may be significant, so caution is required [5]. Summary by Directory - **Spot Prices and Basis**: On September 11, the average price of N - type re - feedstock remained unchanged at 51,550 yuan/ton. The average price of N - type granular silicon also remained unchanged at 48,500 yuan/ton. The basis of N - type materials decreased by 61.80% [5]. - **Futures Prices and Inter - month Spreads**: The main contract price was 53,710 yuan/ton, up 1.56% from the previous day. The spreads between different contracts showed different degrees of change [5]. - **Fundamentals (Weekly)**: The silicon wafer production was 13.88 GW, an increase of 0.73% from the previous week; the polysilicon production was 31,200 tons, an increase of 3.31% [5]. - **Fundamentals (Monthly)**: The polysilicon production was 131,700 tons, an increase of 23.31% from the previous month. The polysilicon import volume increased by 40.30%, and the export volume increased by 5.96% [5]. - **Inventory Changes**: The polysilicon inventory increased by 3.79%, and the silicon wafer inventory decreased by 1.78% [5]. Group 5: Glass and Soda Ash Industry Report Industry Investment Rating Not provided Core Viewpoint - **Soda Ash**: The futures market lacks a main trading logic and is in a narrow - range volatile pattern. The fundamental oversupply problem still exists. Although the inventory did not accumulate this week, it has actually been transferred to the middle and lower reaches, and the trade inventory continues to rise. The previously reduced production capacity has resumed, and the weekly production has returned to a high level of 750,000 tons. In the medium - term, there is no expectation of a significant increase in downstream capacity, so the overall demand for soda ash will continue the previous rigid - demand pattern. After the traditional summer maintenance season in the soda ash industry, with high supply, if there is no actual capacity exit or production reduction in the future, the inventory will be further pressured. Follow the implementation of policies and the production adjustment of soda ash plants. It is recommended to short - sell at high levels when the price rebounds [6]. - **Glass**: The spot market had good trading this week, and the inventory decreased. At the beginning of the week, the news of the conversion of coal - gas production lines to clean energy in the Shahe area triggered a rise in the futures market. The specific conversion time is to be determined, and the expected shutdown time is limited. There are still some plans for production resumption and ignition in the future. Currently, the inventory of manufacturers in the Shahe area is gradually increasing, while the inventory in the middle reaches has not significantly decreased. In terms of industry supply - demand, the deep - processing orders have improved seasonally but are still weak, and the operating rate of low - emissivity glass has remained low, showing no obvious peak - season characteristics. In the long - term, the real - estate cycle is at the bottom, and the completion volume is shrinking. Eventually, the industry needs to clear excess capacity. Follow the implementation of policies in different regions and the inventory replenishment performance of the middle and lower reaches approaching the peak season. Short - term: stay on the sidelines; medium - term: pay attention to the actual peak - season demand [6]. Summary by Directory - **Glass - related Prices and Spreads**: On September 12, the price of glass 2505 was 1282 yuan/ton, up 0.23% from the previous day; the price of glass 2509 was 686 yuan/ton, down 0.60% [6]. - **Soda Ash - related Prices and Spreads**: The price of soda ash 2505 was 1359 yuan/ton, up 0.44% from the previous day; the price of soda ash 2509 was 1168 yuan/ton, up 0.44% [6]. - **Supply**: The soda ash operating rate was 86.22%, down 1.24% from the previous day. The weekly soda ash production was 761,100 tons, up 1.25%. The daily melting volume of float glass was 160,200 tons, up 0.38% [6]. - **Inventory**: The glass inventory decreased by 2.33%, the soda ash factory inventory decreased by 1.35%, and the soda ash delivery warehouse inventory increased by 2.70% [6]. - **Real - estate Data**: The year - on - year growth rate of new construction area was - 0.09%, up 0.09% from the previous period; the growth rate of construction area was 0.05%, down 2.43% [6].

Report Industry Investment Rating - The mid - term outlook for the black building materials industry is "oscillation" [7] Core Viewpoints - The improvement of fundamentals and policy expectations help the sector stabilize periodically. The rapid recovery of hot metal output after the parade boosts the demand for furnace materials, supporting steel prices. Steel enterprises' rapid resumption of production and frequent policy expectations on the supply - side jointly lead to the price stabilization of sector varieties [2]. - The short - term prices of most varieties in the black building materials sector are expected to oscillate. Although there are some supporting factors, there are also limitations and uncertainties in demand and supply [3][7][8] Summary by Related Catalogs 1. Overall Situation of the Black Building Materials Sector - The main futures prices of the sector oscillated strongly yesterday, and the night - session prices oscillated. The statements in the NDRC report triggered small fluctuations in the market. The resumption of production by steel enterprises and policy expectations on the supply - side led to the price stabilization of sector varieties [2] 2. Raw Material Analysis Iron Element - In terms of iron ore, port maintenance led to a significant decline in Brazilian shipments, but the impact on annual shipments is expected to be small. The current demand has returned to the level before the parade restrictions, supporting iron ore demand. However, the peak - season demand for finished products needs to be continuously verified, limiting the upside space of iron ore. It is expected that the short - term iron ore price will oscillate. For scrap steel, the fundamental contradictions are not prominent. The pressure on finished product prices leads to low electric - furnace profits, but resources are still tight, and the short - term price is expected to oscillate [3] Carbon Element - The recovery of steel mills' imported ore consumption to the pre - parade level indicates the recovery of hot metal production. Steel mills still have restocking demand before the National Day, and the short - term price is expected to remain oscillating. The recovery of coal mines is slower than that of downstream hot metal, and safety accidents continue to disrupt the coal - mine production increase rhythm. Under this supply - demand pattern, coal - mine inventories are being depleted at a low level, and there is still restocking expectation downstream before the National Day, so the coking coal price is expected to be supported [3] Alloys - For manganese silicon, a new round of steel tenders has started, and the market is waiting and seeing. The first - round inquiry price in September decreased by 400 yuan/ton month - on - month. The fundamentals lack upward drivers. In the short term, the cost side and peak - season expectations support the futures price, but the medium - and long - term price has a large downward pressure. For ferrosilicon, the first - round inquiry price in September decreased by 330 yuan/ton month - on - month. The short - term cost side still supports the price, and the downward space of the futures price may be limited in the peak - season expectation, but the medium - and long - term price center will tend to decline [4] 3. Individual Product Analysis Steel - The spot market trading volume of steel is average, and the inventory is at a moderately high level. The fundamentals are weak, especially for building materials. Although the cost side has support and there is restocking demand during the peak season, it is expected that the performance of rebar will be weaker than that of hot - rolled coils [8] Iron Ore - The overseas mine shipments and arrivals at 45 ports decreased month - on - month, mainly due to port maintenance in Brazil. The demand has support in the short term as the small - sample hot metal output has recovered. The overall inventory level is moderate. The demand is expected to recover, and steel enterprises' inventories are at a low level, but the peak - season demand for finished products has not been verified, so the short - term price is expected to oscillate [8][9] Scrap Steel - The arrival volume of scrap steel decreased this week. The pressure on finished product prices led to low electric - furnace profits, and the total daily consumption of scrap steel in both long - and short - flow processes decreased. The factory inventory decreased slightly, and the inventory - available days are at a low level. The short - term price is expected to oscillate [10] Coke - The first - round price cut has been implemented, but the coking profit is still considerable, and the supply has basically returned to normal. After the parade, steel mills' production enthusiasm is high, and they maintain on - demand procurement. The coke supply will gradually become loose. With the support of high hot - metal production, steel mills still have restocking demand, and the short - term price is expected to oscillate [11] Coking Coal - Coal mines have basically resumed production, and Mongolian coal imports remain high. The downstream steel and coking enterprises' procurement is cautious, and the upstream inventory is accumulating, but the overall inventory pressure is not prominent. After the parade, the production of coking coal and coke will gradually recover, and the downstream restocking on - demand will support the coking coal price [11] Glass - The actual demand is weak, but there are peak - season and policy expectations. After the mid - stream destocking, there may be another wave of oscillations. In the medium and long term, market - oriented capacity reduction is needed, and if the price returns to fundamental trading, it is expected to oscillate downward [12] Soda Ash - The supply - surplus pattern remains unchanged. After the futures price decline, the spot - futures trading volume increased slightly. It is expected to oscillate widely in the future. In the long term, the price center will decline to promote capacity reduction [15] Manganese Silicon - A new round of steel tenders has started, and the market is waiting and seeing. The first - round inquiry price in September decreased by 400 yuan/ton month - on - month. The fundamentals lack upward drivers. In the short term, the cost side and peak - season expectations support the futures price, but the medium - and long - term price has a large downward pressure [16] Ferrosilicon - The first - round inquiry price in September decreased by 330 yuan/ton month - on - month. The short - term cost side still supports the price, and the downward space of the futures price may be limited in the peak - season expectation, but the medium - and long - term price center will tend to decline [17] 4. Index Information - On September 10, 2025, the comprehensive index of CITIC Futures commodities was 2222.49, down 0.11%; the commodity 20 index was 2487.89, down 0.16%; the industrial products index was 2232.18, up 0.10%.

Domestic asphalt inventory levels increased to 27.11%, a rise of 0.66% week-on-week [4] - The operating rate of domestic asphalt plants decreased to 39.59%, down 0.63% week-on-week [4] - The upcoming demand peak in September is expected to ease supply-demand conflicts, potentially leading to further price increases [4] Rubber - The main rubber contract RU2601 rose by 40 yuan/ton to 15980 yuan/ton, while NR main contract fell by 20 yuan/ton to 12715 yuan/ton [5] - China's natural rubber social inventory decreased by 0.7 million tons, a decline of 0.57% [5] - The market is expected to remain strong due to stable demand and inventory depletion [5] PX, PTA, and MEG - TA601 closed at 4698 yuan/ton, up 0.43%, while EG2601 closed at 4319 yuan/ton, down 0.07% [6] - PX main contract closed at 6770 yuan/ton, up 0.65%, with spot prices at $838 per ton [6] - The PX supply is recovering, and downstream TA is expected to improve as maintenance is completed [6] Methanol - Methanol prices in Taicang were at 2295 yuan/ton, with CFR China prices between $261-$265 per ton [7] - Domestic supply is expected to gradually recover as production resumes, while Iranian shipments remain stable [7] - The market is anticipated to reach a temporary bottom as inventory levels peak after mid-month [7] Polyolefins - Mainstream prices for East China PP were between 6750-6960 yuan/ton, with various production margins reported [8] - Demand is expected to improve with the arrival of the "golden September and silver October" demand season [8] - The market is transitioning towards a balanced supply-demand scenario, but cost pressures remain [8] PVC - PVC market prices in East China are stabilizing, with electric stone method prices ranging from 4620-4730 yuan/ton [9] - Domestic construction activity is recovering, but overall demand remains weak compared to last year [9] - The market faces high inventory pressure, leading to a gradual compression of production profits [9] Urea - Urea prices continued to trend weakly, with the main contract closing at 1669 yuan/ton, down 1.01% [10] - The supply level remains stable, but demand sentiment is weak, with low sales rates reported [10] - The market is under pressure due to inventory increases and limited new export expectations [11] Soda Ash - Soda ash futures prices remained firm, with the main contract closing at 1281 yuan/ton, down 0.47% [12] - The market is stable, with production levels declining due to increased maintenance and equipment changes [12] - Overall, the market lacks new driving forces, but macro sentiment continues to support prices [12] Glass - Glass futures prices showed stability, with the main contract closing at 1181 yuan/ton, down 1.5% [13] - The domestic float glass market average price was 1164 yuan/ton, with a slight increase [13] - Demand sentiment remains positive, but no significant improvements in supply-demand balance are observed [13]

1. Natural Rubber Industry - **Report Industry Investment Rating**: Not provided - **Core View**: The fundamentals of natural rubber have changed little. There is still support from the upstream cost side, while downstream enterprises are resistant to high - priced raw materials. The reference range for the 01 contract is 15,000 - 16,500. Follow - up attention should be paid to the raw material output in the peak season of the main producing areas and whether the La Niña phenomenon affects the supply. If the raw material supply is smooth, consider short - selling at high prices; if the supply is poor, the rubber price is expected to remain high [1]. - **Summary by Section**: - **Spot Price and Basis**: On September 10, the price of Yunnan Guofu mobile phone glue (SCRWF) in Shanghai dropped to 15,050 yuan/ton, a decrease of 1.31%.

Log Industry - **Report Industry Investment Rating**: Not provided - **Core View**: The log market is in a volatile pattern. The spot market is weakening, and the enthusiasm of traders for imports is decreasing. The arrival volume remains low, and the supply in September is expected to continue at a low level. The inventory is continuously decreasing, and the demand remains above 60,000 cubic meters but has not improved significantly. The futures valuation is relatively low, and it is in the stage of bottom - seeking. It is recommended to go long at low prices [4]. - **Summary by Section**: - **Futures and Spot Price**: On September 10, the 2509 contract of logs increased by 0.12%, the 2511 contract increased by 0.06%, and the 2601 contract decreased slightly.

Glass and Soda Ash Industry - **Report Industry Investment Rating**: Not provided - **Core View**: - **Soda Ash**: The futures market continues to be weak and volatile. The fundamental logic of oversupply persists. Although the inventory has not increased significantly this week, it has actually transferred to the middle and lower reaches, and the trade inventory has increased significantly. The weekly production has returned to a high level of 750,000 tons. In the medium - term, the downstream demand for soda ash will remain at the previous rigid - demand level. After the traditional summer maintenance season in the soda ash industry, the supply is high. If there is no actual capacity exit or load reduction, the inventory will be further pressured. It is recommended to short - sell at high prices on rebounds [5]. - **Glass**: The news of the conversion of coal - gas production lines to clean energy in the Shahe area at the beginning of the week triggered a rise in the futures market, but the specific conversion time is undetermined, and the expected shutdown time is limited.

昨日有消息称几内亚政府可能要求矿业公司建设本土冶炼厂，此举或影响西芒杜铁矿的发运预期，推动铁矿盘面大幅上涨，但目前事件仍存在较大不确定性。从交 易逻辑看，市场更倾向于解读为阅兵结束后钢厂复产补库，叠加本期巴西矿发运量下降，情绪面助推价格上行，当前铁水产量预计仍将快速回升至高位，而成材端 仍处于超季节性去库阶段，这种状态下应该收缩利润压供给，但旺季需求尚未被证伪，成材价格继续向下有阻碍，在这个维度下原料借机向上挤压利润。目前成材 仍受超季节性累库压制，盘面上行乏力。打破僵局需等待两类信号，一是旺季需求实质性改善，能够承接高供给并带动去库；二是供给端出现实际收缩，形成成本 强支撑。目前两者均未明朗，反内卷情绪也有所降温，预计近期盘面或仍呈现震荡偏弱，等待旺季需求验证。 | 螺纹、热卷盘面价格. | | | 螺纹、热卷月差. | | | | --- | --- | --- | --- | --- | --- | | | 2025-09-10 | 2025-09-09 | | 2025-09-10 | 2025-09-09 | | 螺纹钢01合约收盘价 | 3109 | 3123 | 螺纹01-05月差 | -47 ...
