对等关税博弈延续，有?维持震荡

1. Report Industry Investment Rating - The report does not explicitly provide an overall industry investment rating. However, individual metal ratings include: Copper - "震荡" (Oscillation); Alumina - "震荡" (Oscillation); Aluminum - "短期仓单数量和累库仍需观察，预计价格区间震荡；中长期消费仍有隐忧，视库存和升贴水拐点区间思路偏逢高空" (Short - term: Observe warehouse receipts and inventory accumulation, expect price range - bound oscillation; Medium - to long - term: Consumption has concerns, consider shorting on rallies based on inventory and premium/discount inflection points); Aluminum Alloy - "震荡" (Oscillation); Zinc - "震荡偏弱" (Oscillation with a weak bias); Lead - "震荡" (Oscillation); Nickel - "震荡偏弱" (Oscillation with a weak bias); Stainless Steel - "震荡" (Oscillation); Tin - "震荡" (Oscillation) [1][5][6][9][10][13][14][16][17][20][21] 2. Core Viewpoints of the Report - The US tariff game continues, and the expectation of domestic policy stimulus is increasing. Overall, the macro - expectation is volatile, and non - ferrous metals will continue to oscillate. In terms of supply and demand, the supply and demand of basic metals are gradually seasonally loosening, and domestic inventories are gradually rising seasonally. In the short - to medium - term, tariff uncertainty and weakening demand expectations suppress prices, while policy stimulus expectations and supply disruptions support prices. Focus on structural opportunities, cautiously consider short - term long positions in aluminum and tin on dips, and short zinc ingots on rallies. In the long - term, the demand prospects of basic metals are still uncertain, and shorting opportunities on rallies for some varieties with excess or expected excess supply and demand can be considered [1] 3. Summary by Related Catalogs 3.1 Copper - Viewpoint: The time for the US copper tariff to take effect may be advanced, and the price of Shanghai copper is under pressure. - Logic: Macroscopically, Trump's claim to impose a 50% tariff on imported copper has led to a significant increase in COMEX copper prices. The US Secretary of Commerce said the tariff may be implemented at the end of the month, weakening the siphon effect on copper in the US and alleviating the tight supply - demand situation in non - US regions, putting pressure on LME and Shanghai copper prices. In terms of supply and demand, copper ore processing fees continue to decline, and raw material supply is still tight. The demand is weakening as the consumption off - season approaches. Domestic and foreign inventories are accumulating again, and the risk of LME squeeze has eased. - Outlook: Copper supply constraints still exist, and inventories are at a low level, but demand is marginally weakening, and the US copper tariff is unfavorable to Shanghai copper prices. It is expected to show an oscillatory pattern [5][6] 3.2 Alumina - Viewpoint: Market rumors suggest that the mining permit issue has eased, and the alumina futures price has declined. - Logic: In the short - to medium - term, there is no shortage of ore, and operating capacity and inventories are gradually rising. The Guinean government's new policies may increase corporate costs and affect the bottom - line expectation of ore prices. - Outlook: Cautious reverse arbitrage [6] 3.3 Aluminum - Viewpoint: Inventory has significantly accumulated, and aluminum prices have declined under pressure. - Logic: The short - term tariff negotiation deadline is postponed, but there is still strong uncertainty. The fundamentals have shown marginal weakening signs, with inventory accumulation, spot discounts, and a decrease in the risk of near - month squeeze. - Outlook: Short - term: Observe warehouse receipts and inventory accumulation, expect price range - bound oscillation; Medium - to long - term: Consumption has concerns, consider shorting on rallies based on inventory and premium/discount inflection points [9] 3.4 Aluminum Alloy - Viewpoint: Demand has entered the off - season, and the futures price has corrected. - Logic: Short - term, ADC12 faces a game between strong cost support and weak demand. The supply of scrap aluminum is tight, while demand is in the off - season. The price difference between ADC12 and A00 is expected to rise in the future. - Outlook: Short - term, ADC12 and ADC12 - A00 oscillate at low levels, following the trend of electrolytic aluminum. There is room for an increase in the future, and cross - variety arbitrage can be considered [10][12] 3.5 Zinc - Viewpoint: Supply and demand are in excess, and zinc prices oscillate weakly. - Logic: Macroscopically, the prices of black - series products are rebounding. The supply of zinc ore is loosening in the short - term, and smelters' profitability is good. Domestic consumption has entered the traditional off - season, and demand expectations are general. Zinc ingot inventories are accumulating, and the support for zinc prices is weakening. - Outlook: In July, zinc ingot production will continue to increase, and downstream demand will enter the off - season. Zinc prices are expected to oscillate weakly [13][14] 3.6 Lead - Viewpoint: Cost support is stable, and lead prices oscillate. - Logic: In the spot market, the discount has narrowed, and the price difference between primary and recycled lead is stable. On the supply side, the price of scrap batteries has decreased slightly, and the production of recycled lead is at a low level. On the demand side, the off - season has not completely passed, but the start - up rate of lead - acid battery factories is higher than the same period in previous years. - Outlook: The US tariff suspension period is postponed to August 1st, but the announced tariffs are high, and the macro - situation is still uncertain. As demand transitions from the off - season to the peak season, the start - up rate of battery factories is recovering. The supply of lead ingots may continue to increase slightly this week. The cost support of recycled lead is stable, and lead prices are expected to oscillate [14][15][16] 3.7 Nickel - Viewpoint: Philippine nickel enterprises are increasing nickel ore exports, and nickel prices will oscillate widely in the short - term. - Logic: Market sentiment still dominates the market, and the industrial fundamentals are marginally weakening. After the rainy season, the supply of raw materials may loosen. The production of intermediate products has recovered, and the price of nickel salts has slightly declined. The inventory has significantly accumulated, and the upward pressure is significant. - Outlook: Philippine nickel enterprises are increasing nickel ore exports to Indonesia. Nickel prices will oscillate widely in the short - term, and long - term trends need further observation [16][17][18] 3.8 Stainless Steel - Viewpoint: Nickel iron prices continue to weaken, and the stainless - steel futures price is running weakly. - Logic: Nickel iron and chrome iron prices are weakening. Although the futures price is rising, the improvement in spot trading volume is limited. In terms of supply and demand, stainless - steel production decreased in June but remained at a high level historically. As demand exits the peak season, there is a risk of weakening demand. Inventory has decreased, and the pressure of structural surplus has been alleviated. - Outlook: The weakening cost weakens the support for steel prices, but beware of the possibility of an expanded scale of production cuts due to long - term profit compression and policy expectations. The demand side is putting pressure on steel prices as it exits the traditional peak season. Focus on inventory changes and cost changes in the future. Stainless steel is expected to oscillate in the short - term [20] 3.9 Tin - Viewpoint: The supply - demand fundamentals are resilient, and tin prices oscillate. - Logic: The shortage of domestic tin ore is intensifying, and the replacement of Indonesian refined tin export licenses has brought new supply problems. The supply - demand fundamentals are tightening, strengthening the bottom support for tin prices. However, the impact of the short - term interruption of Indonesian exports may be limited, and the terminal demand for tin will weaken marginally in the second half of the year. - Outlook: The tightness of the ore end supports the tin price. Whether the tightness at the ore end can further accelerate the transmission to the ingot end will determine the height of the tin price in July. Tin prices are expected to oscillate [21]
