Report Summary 1. Report Industry Investment Rating - No investment rating information is provided in the report. 2. Core View of the Report - It is expected that Shanghai Tin will fluctuate upwards, and attention should be paid to the resistance level at 305,000 yuan/ton. The market shows a bullish atmosphere with increasing volume, open interest, and price. However, the downstream has low acceptance of current high prices and is mostly in a wait - and - see state.

The overall outlook is basically unchanged, but some people point out an increased risk of slower economic activity in the next few months. Six departments jointly issued an implementation plan to enhance the adaptability of consumer goods supply and demand and promote consumption, aiming to optimize the supply structure of consumer goods by 2027. The number of initial jobless claims in the US last week decreased by 6,000 to 216,000, the lowest in seven months. The initial value of US durable goods orders in September increased by 0.5% month - on - month as expected, and the growth rate of core capital goods orders accelerated to 0.9% more than expected [3]. 3.7 Fundamental Situation - The first batch of reopened mines in Myanmar's Wa State has entered the production capacity ramp - up period. However, two tin mines in Malaysia have suspended production, and the production in Africa and Australia has declined unexpectedly. Africa is about to enter the rainy season, so there are still concerns about tin ore supply. Indonesia's refined tin exports decreased significantly in October, alleviating the previous concerns about supply growth. In the smelting end, the raw material shortage in Yunnan is still severe, and the tin ore processing fee remains at a low level. The waste recycling system in Jiangxi is under pressure, and the operating rate remains at a low level, so the production of refined tin is still restricted. On the demand side, there is only a small amount of rigid demand procurement, and the downstream has a low acceptance of current high prices and is basically in a wait - and - see state. The domestic inventory has increased slightly, with a spot premium of 200 yuan/ton. The LME inventory has increased slightly, and the spot premium has risen [3].

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - For precious metals, although central bank gold purchases and growing investment demand will push up the price center in the long - term, the unclear prospect of interest rate cuts in December and short - term technical weakness suggest a possible short - term adjustment. Attention should be paid to the retracement of the 200 - day moving average [3]. - For copper, as the delivery date approaches, the registered warrant volume has rapidly increased. The spot price of electrolytic copper has declined, the premium has strengthened, and the purchasing sentiment has increased but not significantly. The futures price has shown narrow - range fluctuations and lacks driving forces [15]. - For aluminum, the expected tightening of overseas electrolytic aluminum supply has given rise to a bullish sentiment among funds, leading to an influx of capital into Shanghai aluminum futures and an increase in prices. However, downstream demand may not support such high prices, so Shanghai aluminum is expected to fluctuate at a high level. Alumina has seen price - increasing orders due to environmental production restrictions and short - covering, but it still follows an oversupply logic. Cast aluminum alloy has strong follow - up characteristics with Shanghai aluminum and has strong downside support [33][34]. - For zinc, the expectation of interest rate cuts has cooled down, and the smelting sector's willingness to reduce or halt production in November has increased due to intense competition for ores and a significant decline in TC. The impact needs to be observed through inventory changes in November. There is a possibility of inventory reduction if demand remains stable. Currently, there are significant differences between bulls and bears, and the bottom space can be observed at the end of the month [57]. - For nickel, the expectation of interest rate cuts in December is uncertain, and the progress of Sino - US tariffs has affected risk preferences. Nickel ore prices may remain strong in the short term due to the approaching rainy season in the Philippines and the impact of typhoons on production and shipping. The prices of nickel - iron and stainless steel have declined due to weak downstream demand, and both are experiencing inventory accumulation [73]. - For tin, although there has been some resumption of production in Yunnan, the supply is still weaker than demand due to the under - expected resumption of production in Wa State and a sharp reduction in concentrate imports. Shanghai tin is expected to maintain a high - level oscillation, with support predicted around 276,000 yuan [88]. - For lithium carbonate, the price has far exceeded expectations, and downstream buyers have no intention to replenish inventory. There is an expectation of a decline in production in December. Technically, the price has broken through the 90,000 - yuan mark and reached 95,000 yuan, posing a high risk for chasing the price. There is an over - rising sentiment, and the risk of chasing the price should be vigilant [104]. - For the silicon industry chain, the supply - demand pattern of industrial silicon is generally weak, and it is expected to have wide - range fluctuations. The polysilicon industry chain is experiencing production cuts and inventory accumulation, with a weak fundamental outlook and wide - range weak fluctuations [115]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - Gold prices are driven up by the strengthened expectation of a Fed rate cut in September, geopolitical risks in the Middle East and Eastern Europe, and the continuous gold - buying trend of global central banks [3]. - Copper prices are in a state of multi - factor intersection and remain volatile. The upside is limited by weak demand in the automotive, home appliance, and real estate sectors, while the support at 79,000 yuan/ton is solid [15]. - Aluminum prices are expected to be oscillatingly strong in the short term, but there is pressure above. Breaking through the 21,000 pressure level requires the fulfillment of peak - season expectations, a significant improvement in demand, and inventory reduction [35]. - Zinc prices are expected to oscillate in the short term, with the supply in an oversupply state and the demand awaiting the performance of the "Golden September and Silver October" [63]. - Nickel and stainless - steel prices are expected to oscillate within a range, with macro factors leading the market and little change in fundamentals [76]. - Tin prices have an upward driving force due to the tight supply, despite the demand pressure [93]. - Carbonate lithium futures are expected to enter an oscillating and consolidating stage, with attention paid to the environmental protection situation on the supply side and the continuation of downstream restocking [111]. - Industrial silicon prices are expected to oscillate at the bottom in the short term, with a relatively narrow price - fluctuation range [122]. - Polysilicon futures are expected to be oscillatingly strong, supported by the improved fundamentals from industrial integration [123]. 3. Summary by Related Catalogs Precious Metals - **Gold**: The expectation of a Fed rate cut in September has been strengthened to 89%, which suppresses the US dollar and boosts the financial attribute of gold. Geopolitical risks in the Middle East and Eastern Europe increase the demand for hedging, and the continuous gold - buying trend of global central banks provides long - term support, jointly driving up the gold price [3]. - **Silver**: No specific daily - view analysis provided, mainly shows relevant price and inventory data [4][12]. Copper - **Price**: The latest price of Shanghai copper futures shows an increase, with the daily increase of the main contract being 0.47%. The price of LME copper 3M also increases by 0.68%. The support at 79,000 yuan/ton is solid, but the upside is limited by weak demand [15][16]. - **Supply - demand**: The spot premium increases with the price increase, and the refined - scrap price difference is close to a reasonable level. The demand in the automotive, home appliance, and real estate sectors is weak, and the supply may shrink after September due to Fed rate cuts and maintenance [15]. Aluminum - **Aluminum**: The expectation of a Fed rate cut in September and domestic policies are beneficial to the price. The start - up rate of electrolytic aluminum has increased slightly, and the demand shows signs of recovery in the peak season, but the production and transportation control during the September parade may affect inventory reduction. The possible reduction in recycled aluminum supply supports the consumption of primary aluminum [35]. - **Alumina**: The supply of alumina is expected to be in a state of oversupply in the second half of the year, which suppresses the price. The environmental protection limit order for some alumina plants in Henan has only a short - term impact on production [36]. - **Casting Aluminum Alloy**: The supply of scrap aluminum is tight, and the cancellation of tax - return policies for some recycled aluminum enterprises may lead to a decline in the capacity utilization rate of waste - using enterprises, providing support for the price of aluminum alloy [37]. Zinc - **Supply**: The supply is in an oversupply state. The domestic zinc - ore price has an advantage, and the overseas zinc - ore supply is relatively loose. The increase in domestic processing fees in September may not be large, and the overseas refined - zinc increment is small [63]. - **Demand**: The demand is not significantly affected by the parade and remains stable. It is expected to improve during the "Golden September and Silver October", and there is a strong positive correlation with black varieties [63]. - **Inventory**: The LME inventory continues to decline, and the pattern of strong overseas and weak domestic zinc prices is more obvious [63]. Nickel - **Market Trend**: The nickel and stainless - steel markets oscillated last week, with macro factors leading the market and little change in fundamentals. The support of nickel ore continues, and the upward space of nickel iron needs attention. The new - energy sector was relatively strong last week [76]. Tin - **Supply - demand**: Tin prices are rising due to tight supply. Yunnan Tin plans to stop production for maintenance for 45 days starting from August 30. In August 2025, the output of refined tin decreased both month - on - month and year - on - year, mainly due to enterprise maintenance and the decrease in tin - concentrate imports in July [93]. Carbonate Lithium - **Market Sentiment**: The sentiment in the futures market declined last week, and the spot - market trading volume decreased. The production - scheduling data of downstream lithium - battery material enterprises increased by 5% month - on - month this month, providing support for the peak - season expectation. The futures market is expected to enter an oscillating and consolidating stage [111]. Silicon Industry Chain - **Industrial Silicon**: The downward space of industrial silicon is limited, and it is expected to oscillate at the bottom in the short term, with a relatively narrow price - fluctuation range [122]. - **Polysilicon**: Polysilicon futures are expected to be oscillatingly strong, supported by the improved fundamentals from industrial integration [123].

Report Summary 1. Report Industry Investment Rating - No investment rating provided in the report. 2. Report's Core View - The tin price has been fluctuating recently. The downstream enterprises mostly make rigid - demand purchases when the price is low, and there are some post - point - price orders.

Fundamentally, although Myanmar's Wa State has restarted the mining license approval, actual ore production will not start until the fourth quarter; the Congo Bisie mine plans to resume production in stages, and the tin ore processing fee remains at a historical low. On the smelting side, the output increase in July was affected by multiple factors such as the resumption of production by some enterprises and the cleaning of intermediate products, but the raw material shortage in Yunnan is still severe, and the waste recycling system in Jiangxi is under pressure, with the operating rate remaining at a low level. On the demand side, downstream processing enterprises are in the traditional off - season, with most enterprises only maintaining rigid - demand production and receiving goods, and the orders are unsatisfactory. Recently, the tin price has been fluctuating, with most downstream enterprises making rigid - demand purchases at low prices, and some post - point - price orders.

Technically, the open interest has decreased, both long and short are cautious, and the lower - shadow positive line indicates support, with the price expected to fluctuate within a range [3] 3.8重点关注 - There is no news today [3]
