Core Viewpoint - The current real estate market in China is undergoing significant adjustments, with varying conditions across different cities, leading to a complex decision-making process for potential homebuyers [1][2][12] Market Overview - In Q1 2025, the national sales area of commercial housing decreased by 8.3% year-on-year, and sales revenue fell by 10.2%. Compared to the peak in 2018, the transaction volume has shrunk by nearly 40%, indicating a deep adjustment period in the real estate market [1][4] - The inventory of commercial housing reached approximately 680 million square meters by the end of March 2025, with a depletion cycle of nearly 22 months, significantly exceeding the reasonable level of 12-18 months [4][5] Price Trends - The housing price differentiation across cities is notable, with three tiers identified: - First-tier cities (e.g., Beijing, Shanghai) have stabilized prices with slight increases in core areas, such as a 1.2% rise in Shanghai's core area in Q1 2025 [4] - Second-tier cities (e.g., Hangzhou, Nanjing) show a trend of stability with some declines, particularly in suburban areas [4] - Third-tier cities are experiencing continuous price declines, with some areas seeing drops exceeding 30% [4][5] Demographic Changes - China's population is undergoing significant changes, with a reported decline of approximately 950,000 in 2024. By 2035, over 20% of the population is expected to be over 65 years old, indicating a shift towards a deeply aging society [7] - The decrease in total population suggests a narrowing of housing demand, while the trend of population concentration in major cities continues, leading to market differentiation [7] Financial Environment - Since the second half of 2024, mortgage rates have been decreasing, with the average rate for first-time homebuyers dropping to around 3.8%, a historical low [7] - Various regions have relaxed purchasing restrictions, including lowering down payment ratios and easing purchase limits, which have somewhat boosted market confidence [7] Housing Affordability - The average housing price-to-income ratio across 50 major cities is now 8.6, down from 11.3 in 2018, indicating improved affordability. The ratios for first-tier cities stand at 12.5, while second-tier cities are at 8.2, and third-tier cities at 6.7 [7] Buyer Strategies - For first-time homebuyers with stable income, now may be a favorable time to enter the market, especially in first and second-tier cities where promotional efforts by developers are strong [9] - Existing homeowners looking to upgrade should consider a "sell first, buy later" strategy to maximize negotiation power in the current market [9] - Investors should be cautious, focusing on prime locations in first-tier and strong second-tier cities, as short-term appreciation is less likely [9][10] - Those unable to afford ideal housing or uncertain about their future location may choose to wait, but should be aware that prime resources in major cities may become scarcer [10] Key Considerations - Personal financial health is crucial, with a recommendation that monthly mortgage payments should not exceed 40% of household income [10] - Location selection is vital, as properties in quality areas tend to retain value better even during market downturns [10] - The quality of the property itself is increasingly important, with well-constructed and well-located properties showing resilience in value [10] - Awareness of urban development plans can significantly influence long-term property value, as infrastructure improvements can enhance desirability [11]

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]

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views Copper - Short - term copper price is expected to oscillate strongly, with the main contract reference range of 79,500 - 82,000 yuan/ton. The short - term improvement in interest - rate cut expectations boosts copper prices, but the long - term impact of interest - rate cuts on copper prices depends on the reasons and macro background. The fundamentals show a state of "weak reality + stable expectations" [1]. Aluminum - Alumina futures are expected to oscillate in the range of 2,900 - 3,200 yuan/ton in the short term. The supply pressure is significant, and the demand stimulation is limited. The price is under pressure from inventory accumulation, but the downside space is relatively limited. Aluminum prices are expected to oscillate around the realization of peak - season expectations and actual consumption, with the main contract reference range of 20,600 - 21,400 yuan/ton. If demand improvement is less than expected, the price may fall after rising [4]. Aluminum Alloy - The price of cast aluminum alloy is expected to remain firm, and the inventory accumulation rate will slow down. The price difference between aluminum alloy and aluminum is expected to further converge. The short - term main contract reference operating range is 20,200 - 20,800 yuan/ton [5][6]. Zinc - Zinc prices are expected to oscillate, with the main contract reference range of 21,800 - 22,800 yuan/ton. Under the background of improved interest - rate cut expectations, non - ferrous metal prices are generally strong, but zinc shows relatively weak performance. The supply is expected to be loose, and the upward space is limited, but the price may be driven up by the macro - environment in the short term [8]. Tin - Tin prices are expected to remain in a high - level oscillation. If the supply from Myanmar recovers smoothly, a short - selling strategy can be considered; if the supply recovery is less than expected, the price is expected to continue to oscillate at a high level, with the operating range of 265,000 - 285,000 yuan/ton [11]. Nickel - Nickel prices are expected to oscillate in a strong range, with the main contract reference range of 120,000 - 125,000 yuan/ton. The macro - environment is favorable, but the medium - term supply is expected to be loose, which restricts the upward space of prices [13]. Stainless Steel - Stainless steel prices are expected to oscillate in the short term, with the main contract reference range of 12,800 - 13,400 yuan/ton. The macro - expectations are improved, and the cost is supported, but the peak - season demand has not been significantly released [15]. Lithium Carbonate - Lithium carbonate prices are expected to oscillate strongly in the short term, with the main price center of reference in the range of 70,000 - 75,000 yuan/ton. Policy windows boost the macro - expectations, and the demand is optimistic, while the supply path is becoming clearer [17]. 3.

Group 1: Natural Rubber Industry Report Industry Investment Rating Not provided Core Viewpoints The fundamentals of natural rubber have changed little. The upstream cost side still provides support, 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 in the peak production season of the main producing areas and the possible impact of the La Nina phenomenon on supply. If the raw material supply is smooth, consider short - selling; if not, the rubber price is expected to remain high [1]. Summary by Relevant Catalogs - **Spot Prices and Basis**: On September 15, the price of Yunnan state - owned standard rubber (SCRWF) was 15,000 yuan/ton, up 0.33% from September 12. The full - latex basis decreased by 14.37%. The price of Thai standard mixed rubber increased by 1.34%. The price of cup rubber in the international market decreased by 0.67%, while the price of glue increased by 0.36%. Some domestic raw material prices remained unchanged [1]. - **Inter - month Spreads**: The 9 - 1 spread decreased by 4.46%, the 1 - 5 spread increased by 75.00%, and the 5 - 9 spread increased by 2.91% [1]. - **Fundamental Data**: In July, Thailand's production increased by 1.61%, Indonesia's by 12.09%, India's decreased by 2.17%, and China's decreased by 1.27%.

Group 2: Glass and Soda Ash Industry Report Industry Investment Rating Not provided Core Viewpoints - **Soda Ash**: The overall sentiment of the commodity market has improved, and soda ash has rebounded due to macro - sentiment. However, the fundamental oversupply problem still exists. In the medium - term, downstream demand will remain at the previous rigid - demand level. After the traditional summer maintenance season, with high supply, if there is no actual production capacity exit or load reduction, inventory will face further pressure. It is advisable to short on rebounds [3]. - **Glass**: The glass market has rebounded due to the improvement of the macro - atmosphere. Last week, the spot market had good transactions and inventory decreased. However, the inventory in the middle reaches has not been significantly reduced. In the long - term, the real - estate cycle is at the bottom, and the industry needs to clear excess capacity. Short - term: stay on the sidelines; medium - term: pay attention to the actual demand in the peak season [3]. Summary by Relevant Catalogs - **Glass - related Prices and Spreads**: The prices of glass in North China, East China, Central China, and South China remained unchanged. The glass 2505 contract increased by 0.16%, and the glass 2509 contract decreased by 2.12% [3]. - **Soda Ash - related Prices and Spreads**: The prices of soda ash in North China, East China, Central China, and Northwest China remained unchanged.

Group 3: Log Industry Report Industry Investment Rating Not provided Core Viewpoints The log market shows a pattern of "weak supply and demand, stable prices, and slightly decreasing inventory". The core contradiction lies in the game between weak demand and fluctuating supply. Prices are temporarily stable with cost support. Follow - up attention should be paid to the improvement of shipment volume in the seasonal peak season. Currently, the 09 contract has new registered warehouse receipts, and the spot market pressure has increased. It is recommended to go long on dips [4]. Summary by Relevant Catalogs - **Futures and Spot Prices**: On September 15, the log 2509 contract decreased by 0.39%, the log 2511 contract increased by 0.81%, and the log 2601 contract decreased by 1.15%.

Group 4: Industrial Silicon Industry Report Industry Investment Rating Not provided Core Viewpoints The cost of industrial silicon is expected to rise as raw material prices increase and the electricity price in the southwest region will go up during the dry season. Although the current output of industrial silicon has increased month - on - month, there are also news of capacity clearance. Considering the possible impact of the polysilicon enterprise self - discipline meeting next week and the increasing demand for downstream replenishment before the National Day, the price of industrial silicon may rise slightly. It is recommended to go long on dips, but also be aware of the inventory and warehouse - receipt pressure. The main price fluctuation range is expected to be 8,000 - 9,500 yuan/ton [5]. Summary by Relevant Catalogs - **Spot Prices and Main - contract Basis**: On September 15, the price of East China oxygen - passing SI5530 industrial silicon remained unchanged, and the basis decreased by 12.09%.

Group 5: Polysilicon Industry Report Industry Investment Rating Not provided Core Viewpoints In the short term, the market is more focused on the expectation of policy implementation in September, and the market is prone to rise and difficult to fall. Fundamentally, the overall supply reduction in September is not obvious as some factories resume production to make up for the supply reduction. The silicon wafer production schedule has increased slightly month - on - month, and there may be a slight inventory build - up in September. The downstream has accepted the price increase of polysilicon, and the spot transmission mechanism is smooth. In the future, the market pays less attention to fundamentals and more to policy expectations, so the price fluctuation risk is high. It is advisable to be cautious and follow the situation of the polysilicon enterprise self - discipline meeting next week [6].
