Report Industry Investment Rating - Unilateral: Cautiously bullish. - Arbitrage: Neutral. [5] Core View - Overseas premiums have strengthened further, LME inventories have continued to decline, and the risk of warehouse receipts has intensified. The export profit of refined zinc in China has continued to expand, and the profit of overseas selling for delivery has emerged, which will stimulate later exports and help reduce domestic social inventories. The domestic smelters are still actively purchasing domestic ores, and the domestic ore TC has continued to decline. Although imported ores are still expensive due to the internal and external zinc price ratio, there is also a possibility that the processing fees will follow suit. In the spot market, with the opening of the export window, the later social inventory is expected to accumulate less than expected, or even show a seasonal de - stocking trend, and the actual consumption performance exceeds expectations. Although smelting still has profits, the comprehensive smelting profit has narrowed due to the decline of domestic TC. If this situation persists or the sulfuric acid price drops, it will also hit the smelting enthusiasm, and the domestic supply pressure is expected to ease. The macro - positive factors still exist, and the previous bearish logic of zinc prices has begun to change. [4] Summary by Related Catalogs Important Data Spot - LME zinc spot premium is $338.74 per ton. SMM Shanghai zinc spot price increased by 200 yuan/ton to 22,100 yuan/ton compared with the previous trading day, and the SMM Shanghai zinc spot premium/discount is - 55 yuan/ton.

Report Summary 1. Report Industry Investment Rating - Unilateral: Cautiously bearish. [5] - Arbitrage: Neutral. [5] 2. Core View - Zinc prices have declined, and there is restocking behavior in the spot market, but social inventories are increasing and are about to exceed the average of the past five years. Spot liquidity has improved, but procurement remains cautious. The TC of domestic and imported zinc ores continues to rise, leading to higher smelting profits and sustained smelting enthusiasm. The supply is expected to increase, and the pressure on the supply side is becoming more prominent. Even during the peak consumption season, the domestic inventory accumulation is expected to continue, and if the consumption peak expectations are not met, zinc prices will face significant pressure. [4] 3. Summary by Related Catalogs Important Data - **Spot**: The LME zinc spot premium is $139.83 per ton. The SMM Shanghai zinc spot price is -90 yuan/ton to 21,920 yuan/ton compared to the previous trading day, with a spot premium of -40 yuan/ton.

[3] Market Analysis - Zinc prices have dropped, and there is restocking in the spot market, but social inventories are increasing and are approaching the five - year average. Spot liquidity has improved, but procurement remains cautious. The TC of domestic and imported zinc ores continues to rise, smelting profits are increasing, and smelting enthusiasm is high. The supply is expected to increase, and the inventory accumulation in China is expected to continue even during the peak consumption season. If the consumption peak expectations are not met, zinc prices will face significant pressure. [4] Strategy - Unilateral: Cautiously bearish. [5] - Arbitrage: Neutral. [5]

1. Report Industry Investment Rating - The rating for unilateral trading is cautiously bullish, and the rating for arbitrage is neutral [5] 2. Core View of the Report - LME inventory has slightly increased, but the absolute value remains below 40,000 tons, leading to a rapid increase in overseas premiums. The domestic supply pressure persists, but the opening of the export window has reversed the short - allocation logic. The linkage between domestic and overseas zinc prices will strengthen, and there's no need to be overly pessimistic about the long - term impact of tariffs [4] 3. Summary by Related Catalogs Important Data - **Spot**: LME zinc spot premium is $201.60 per ton. SMM Shanghai zinc spot price is 22,210 yuan per ton, with a premium of - 55 yuan per ton; SMM Guangdong zinc spot price is 22,210 yuan per ton, with a premium of - 55 yuan per ton; Tianjin zinc spot price is 22,220 yuan per ton, with a premium of - 45 yuan per ton [1] - **Futures**: On October 14, 2025, the main SHFE zinc contract opened at 22,330 yuan per ton, closed at 22,220 yuan per ton, down 65 yuan per ton from the previous trading day. The trading volume was 124,307 lots, and the position was 95,194 lots. The highest price was 22,335 yuan per ton, and the lowest was 22,210 yuan per ton [2] - **Inventory**: As of October 14, 2025, the total inventory of SMM seven - region zinc ingots was 163,100 tons, a change of 12,900 tons from the previous period. The LME zinc inventory was 38,600 tons, a change of 1,125 tons from the previous trading day [3] Market Analysis - LME inventory has a slight rebound, but the absolute value is still low, causing the overseas premium to quickly break through $200 per ton. The domestic smelting profit has narrowed, but the supply pressure remains. The opening of the export window has changed the short - allocation logic, and the linkage between domestic and overseas prices will strengthen. There's no need to be overly pessimistic about the long - term impact of tariffs [4] Strategy - Unilateral trading is recommended to be cautiously bullish, and arbitrage is neutral [5]

Report Title - **Title**: Nonferrous Metals Weekly - Zinc [1] - **Date**: October 13, 2025 [2] - **Author**: Qi Yurong [2] Investment Rating - No investment rating provided in the report. Core Viewpoint - The current domestic zinc market has no substantial improvement in demand, while the supply remains loose. The fundamental situation maintains a pattern of strong supply and weak demand. Coupled with macro - sentiment disturbances, zinc prices may face pressure. Considering the continuous inventory reduction of LME zinc and the deepening of the back structure, the downward space of SHFE zinc may be limited under the boost of the external market. The operating range is expected to be between 22,000 - 23,000 yuan/ton. Continued attention should be paid to changes in macro - sentiment and the opening of the ingot export window [3].

Copper prices are expected to adjust in the short - term but remain optimistic in the long - run; aluminum prices may face short - term pressure; zinc prices are likely to remain weakly volatile; lead prices are expected to oscillate within a range; nickel prices are subject to supply uncertainties; tin prices are supported by supply tightness and demand recovery; industrial silicon and polycrystalline silicon markets are in a wait - and - see state; and lithium carbonate prices are expected to fluctuate widely [2][3] 3. Summary According to Relevant Catalogs 3.1 Macro - **Global Market Flash Crash**: On the night of October 10, Trump's announcement of a 100% tariff on China led to a global market sell - off. US stocks, crude oil, metal futures, and cryptocurrencies all tumbled. The US will raise the tariff on Chinese goods to 130% and implement key software export controls on November 1 [11]. - **US Government "Shutdown"**: The US government "shutdown" entered its 10th day, with federal employee lay - offs starting. The Department of Labor's data release was affected, and high - frequency economic data was difficult to obtain [12]. - **China's Economic Data**: China's September official manufacturing PMI rose to 49.8, the non - manufacturing business activity index was 50.0%, and the composite PMI output index was 50.6%. The central bank increased its gold reserves by 40,000 ounces in September, the 11th consecutive monthly increase [15][16]. - **US Economic Data**: US economic data in September was generally weak. The ADP employment number decreased by 32,000; the ISM manufacturing PMI contracted for the seventh consecutive month; and the ISM services PMI was 50, significantly lower than expected [19][20][21] 3.2 Metal Market Copper - **Price Trend**: Copper prices showed a pattern of rising and then falling. After Freeport declared force majeure at its Grasberg copper mine in Indonesia in late September, prices rose significantly but were limited by weak demand. On October 10, due to the escalation of Sino - US trade tensions, copper prices dropped sharply [2]. - **Market Outlook**: In the short - term, the market is expected to be weakly volatile and may adjust further. However, in the long - run, the supply - demand balance remains tight, and prices are likely to stabilize after the short - term adjustment. It is recommended to reduce long - position holdings to avoid short - term risks [2] Aluminum - **Price Trend**: Aluminum prices fell from high levels. The price of Guinea's bauxite decreased, and the alumina market was under pressure. Trump's tariff signal led to short - term pressure on aluminum prices [2]. - **Market Outlook**: Although short - term prices may continue to decline, the demand peak season remains unchanged, and downstream开工 rates are expected to rise. It is recommended that long - position holders pay attention to risk avoidance and monitor the development of events [2] Zinc - **Price Trend**: Zinc prices rose and then fell. The weak US employment data increased the market's expectation of an interest rate cut, leading to a rebound in zinc prices. However, the overall terminal consumption was weak [2]. - **Market Outlook**: The domestic refined zinc output is expected to remain high, but demand is weak. It is expected that zinc prices will remain weakly volatile, with the main contract operating in the range of 21,500 - 22,500 yuan/ton. It is recommended to conduct range - based short - biased trading [2] Lead - **Price Trend**: Lead prices oscillated horizontally. The domestic lead supply showed a downward trend, and the price recovered after a sharp drop. However, due to the new round of Sino - US trade confrontation, there is a risk of sharp fluctuations [2]. - **Market Outlook**: It is expected that lead prices will oscillate within the range of 17,000 - 17,800 yuan/ton. It is recommended to conduct range - based trading [2] Nickel - **Price Trend**: Nickel prices oscillated within a range. The new RKAB approval policy in Indonesia has brought uncertainties to the nickel ore market. The supply of refined nickel is in an oversupply situation, and the price of nickel iron has limited upside potential [3]. - **Market Outlook**: It is recommended to wait and see or moderately hold short positions at high prices. The main contract of nickel is expected to operate in the range of 120,000 - 122,000 yuan/ton; for stainless steel, range - based trading is recommended, with the main contract operating in the range of 12,600 - 13,000 yuan/ton [3] Tin - **Price Trend**: Tin prices oscillated within an upward channel. The supply of tin ore is tight, and the downstream semiconductor and photovoltaic industries are showing signs of recovery. However, the short - term tariff increase expectation has a negative impact on prices [3]. - **Market Outlook**: It is recommended to conduct range - based trading, with the reference range for the SHFE tin 11 contract being 260,000 - 290,000 yuan/ton. Attention should be paid to the supply resumption and downstream demand recovery [3] Industrial Silicon and Polycrystalline Silicon - **Price Trend**: Industrial silicon prices fluctuated widely, and polycrystalline silicon prices oscillated at high levels. The production and inventory of industrial silicon and polycrystalline silicon showed different trends, and the photovoltaic industry's anti - involution policy has not been implemented [3]. - **Market Outlook**: Given the current supply - demand expectations for October, it is recommended to wait and see until the policy becomes clear [3] Lithium Carbonate - **Price Trend**: Lithium carbonate prices oscillated horizontally. The supply is in a tight - balance state, and the demand from the energy storage terminal is good. However, there are risks related to mining permits [3]. - **Market Outlook**: It is expected that the price will continue to fluctuate widely. It is recommended to trade cautiously and pay attention to the progress of mining permits in Yichun and the resumption of production at the Ningde Jianxiawo lithium mine [3]

Report Industry Investment Rating - Unilateral: Cautiously bullish. Arbitrage: Neutral [4] Core View - The opening of the export window weakens the short - allocation value of SHFE zinc. Although the domestic supply pressure remains, the export window opening and the change in domestic TC make the short - allocation logic change marginally. The SHFE zinc price will be more sensitive to overseas macro - positive factors, and the linkage between domestic and overseas markets will strengthen. With the LME inventory below 38,000 tons and the overseas premium rising, there is still a warrant risk. Despite short - term fluctuations caused by the tariff trade war, the long - term interest rate cut expectation remains unchanged, and there is no need to be overly pessimistic about the tariff impact [3] Summary by Related Catalogs Important Data - On October 10, 2025, the SHFE zinc main contract closed at 22,270 yuan/ton, with a fluctuation of 0.32%, and the LME price closed at $2,984.5/ton, with a fluctuation of - 0.01%. The spot prices in East China, Guangdong, and Tianjin were 22,300 yuan/ton, 22,320 yuan/ton, and 22,310 yuan/ton respectively, with different changes in the premium/discount to the main contract compared to the previous period. The LME (0 - 3) premium was $66.80/ton, with a weekly change of + $7.69/ton [1] - The weekly processing fee for domestic zinc concentrates by SMM was 3,500 yuan/metal ton, with a weekly change of - 150 yuan/ton, and the weekly processing fee index for imported zinc concentrates was $118.50/dry ton, with a weekly change of $2.60/dry ton. The import profit and loss of zinc concentrates was - 2,379.03 yuan/ton [1] - The operating rates of galvanizing, die - casting zinc alloy, and zinc oxide enterprises were 46.83% (a change of - 1.83% compared to last week), 46.51% (a change of - 0.35% compared to last week), and 56.08% (a change of - 1.24% compared to last week) respectively [1] Inventory - As of October 9, 2025, the total inventory of zinc ingots in SMM's seven major regions was 150,200 tons, an increase of 8,800 tons compared to the previous week. The warrant inventory was 60,644 tons, and the LME zinc inventory was 37,950 tons [2] Profit - As of October 10, 2025, the production profit of smelting enterprises (excluding by - product income) was about - 436 yuan/ton. The sulfuric acid price in Inner Mongolia was 735 yuan/ton, with no change compared to the previous week. After adding by - product income, the profit was about 1,100 yuan/ton [2] Market Analysis - Domestic smelters have low enthusiasm for purchasing domestic zinc ores. The domestic TC and imported TC continue to diverge, and the domestic TC declines. Although the domestic supply has not changed significantly, the opening of the export window changes the short - allocation logic marginally. The LME inventory is below 38,000 tons, and the overseas premium is rising, with a warrant risk. The tariff trade war causes short - term fluctuations, but the long - term interest rate cut expectation remains unchanged, and there is no need to be overly pessimistic about the tariff impact [3] Strategy - Unilateral: Cautiously bullish. Arbitrage: Neutral [4]
