IMF上调全球经济增长，有色暂获支撑

1. Report Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Viewpoints of the Report - IMF's upward revision of the global economic growth forecast provides temporary support for the non - ferrous metals sector. However, the uncertainty of US tariffs and the expectation of weakening demand still suppress prices, while policy stimulus expectations and supply disruptions support prices. Attention should be paid to structural opportunities, such as short - term long positions in aluminum and tin at low prices and short positions in zinc ingots at high prices. For the long - term, short - selling opportunities at high prices can be considered for some varieties with supply surpluses or expected surpluses [1]. - Different non - ferrous metal varieties have different market trends. Copper is expected to fluctuate due to the approaching expiration date of reciprocal tariffs; alumina will continue to fluctuate widely; aluminum prices will fluctuate narrowly with a continuous inventory accumulation trend; aluminum alloy will fluctuate in a weak off - season atmosphere; zinc prices will fluctuate weakly; lead prices will fluctuate with stable cost support; nickel prices will fluctuate widely; stainless steel will fluctuate; and tin prices will fluctuate with inventory accumulation [1][2]. 3. Summary by Relevant Catalogs 3.1行情观点 3.1.1 Copper - Viewpoint: As the expiration date of reciprocal tariffs approaches, copper prices will fluctuate. - Information Analysis: The Chilean Finance Minister hopes that the 50% tariff on copper can be exempted. Trump plans to impose a 50% tariff on imported copper, and the new tariff may be implemented at the end of July or August 1st. In June, China's electrolytic copper production decreased slightly month - on - month but increased year - on - year. As of July 28th, copper inventory increased. On July 29th, the spot price of 1 electrolytic copper had an average premium of 110 yuan/ton over the 2508 contract [8]. - Main Logic: Macroscopically, investors are becoming more cautious as the tariff expiration date approaches, weakening the upward momentum of copper prices. The supply of raw materials is still tight, increasing the risk of smelter production cuts. The copper rod operating rate has declined, and inventory has increased. - Outlook: Copper supply constraints remain, and inventory is still low, but demand is weakening marginally. The implementation of US copper tariffs is not conducive to Shanghai copper prices, so copper is expected to show a fluctuating pattern [9]. 3.1.2 Alumina - Viewpoint: With a large - scale cancellation of warehouse receipts, alumina will continue to fluctuate widely. - Information Analysis: On July 29th, the spot price of alumina increased in various regions. The supply of Guinea's bauxite may tighten during the rainy season, but the overall market surplus pattern will suppress prices. On July 29th, the alumina warehouse receipts decreased by 4823 tons to 4208 tons [9][10]. - Main Logic: In the short term, the alumina market is dominated by anti - involution sentiment and low warehouse receipts. Fundamentally, smelter production capacity is increasing, and the market is in a surplus state with rising inventory. However, the large - scale cancellation of warehouse receipts and the low level of warehouse receipt inventory may support prices. - Outlook: In the short term, alumina is expected to maintain high - volatility and wide - range fluctuations. Attention should be paid to anti - involution sentiment and warehouse receipt issues [10][11]. 3.1.3 Aluminum - Viewpoint: With the continuous inventory accumulation trend, aluminum prices will fluctuate narrowly. - Information Analysis: On July 29th, the average price of SMM AOO aluminum decreased by 40 yuan/ton. As of July 28th, the inventory of electrolytic aluminum ingots and aluminum rods in the main consumption areas in China changed. On July 29th, the Shanghai Futures Exchange's electrolytic aluminum warehouse receipts decreased by 524 tons. Relevant policies for the stable growth of key industries are expected to be introduced. Hydro's Q2 production data shows a slight increase in aluminum production. The US has reached trade agreements with the EU, the Philippines, and other countries [11][12]. - Main Logic: In the short term, the approaching tariff deadline, a slight rebound in the US dollar, and the cooling of anti - involution policy expectations. The supply - side production capacity and operating rate are at a high level, while the demand - side off - season atmosphere is emerging, and the operating rate of primary processing is declining. Inventory is accumulating, and the spot basis is flat. - Outlook: In the short term, the consumption situation and inventory accumulation rhythm need to be observed, and prices are expected to fluctuate within a range. In the long term, there are concerns about consumption, and a short - selling strategy at high prices can be considered based on the premium and inventory inflection point [12]. 3.1.4 Aluminum Alloy - Viewpoint: In a strong off - season atmosphere, the market will fluctuate. - Information Analysis: On July 29th, the price of Baotai ADC12 remained unchanged. In June 2025, China's scrap aluminum imports decreased year - on - year. Thailand plans to implement carbon tax policies. An aluminum alloy project in Anhui started construction with a total investment of about 2 billion yuan [13]. - Main Logic: In the short term, ADC12 is in a game between strong cost support and weak demand. The supply of scrap aluminum is tight, but the previous imports have increased, and the anti - involution sentiment has cooled, resulting in a marginal decline in scrap aluminum prices. The operating rate of recycled aluminum alloy is low, and inventory is accumulating. The demand is in the off - season, and downstream enterprises purchase on a just - in - time basis. - Outlook: In the short term, ADC12 and the ADC12 - A00 spread will fluctuate at a low level, and the market will follow electrolytic aluminum. In the future, there is room for the spread to rise, and cross - variety arbitrage can be considered [13][15]. 3.1.5 Zinc - Viewpoint: With the cooling of anti - involution sentiment, zinc prices will fluctuate weakly. - Information Analysis: On July 29th, the spot price of zinc in different regions had different discounts to the main contract. As of July 29th, the inventory of zinc ingots in seven regions increased. The Xinjiang Huoshaoyun lead - zinc smelting project was put into production, with an annual zinc production capacity of 560,000 tons [15]. - Main Logic: Macroscopically, the anti - involution sentiment has cooled, but there are still expectations of domestic policy stimulus. The US dollar index has support, but its rebound is limited. The supply of zinc ore has become looser, and smelters' profitability is good, with strong production willingness. The demand is in the traditional off - season, and the overall demand expectation is average. - Outlook: In July, zinc ingot production will increase, and demand will weaken, leading to inventory accumulation. Zinc prices are expected to fluctuate weakly [16]. 3.1.6 Lead - Viewpoint: With stable cost support, lead prices will fluctuate. - Information Analysis: On July 29th, the price of waste electric vehicle batteries remained unchanged, and the price difference between primary and recycled lead was stable. The average price of SMM1 lead ingots remained unchanged, and the spot premium increased by 25 yuan. As of July 28th, lead ingot inventory increased slightly. The supply of primary lead is still tight, while the production of recycled lead has recovered [16][17]. - Main Logic: In the spot market, the spot discount has narrowed slightly, and the price difference between primary and recycled lead is stable. The price of waste batteries is stable, and the operating rate of recycled lead smelters has increased. The production capacity of primary lead smelters has not fully recovered, and the weekly production of lead ingots has increased slightly. The demand is in the transition period from the off - season to the peak season, and the operating rate of lead - acid battery factories has increased [17][18]. - Outlook: Although the US reciprocal tariff suspension period has been postponed to August 1st, the announced tariff is high, causing macro - level fluctuations. As demand transitions from the off - season to the peak season, the battery factory operating rate has recovered. The supply of lead ingots may continue to increase slightly this week. The cost of recycled lead is supported at a high level, so lead prices are expected to fluctuate [18]. 3.1.7 Nickel - Viewpoint: With fluctuating market sentiment, nickel prices will fluctuate widely. - Information Analysis: On July 29th, LME nickel inventory increased, and Shanghai nickel warehouse receipts decreased. Indonesia plans to invest in the nickel downstream industry, and some companies have adjusted their production forecasts. Vale Indonesia plans to raise funds for nickel projects. The Indonesian Nickel Mining Association proposes to revise the HPM formula, and the Indonesian government will implement a new RKAB system. The export volume of the Philippines to Indonesia is expected to increase [18][19][20]. - Main Logic: Currently, market sentiment dominates the market, and the static valuation of the market is stable. The industrial fundamentals are weakening marginally. After the rainy season, the supply of raw materials may be looser. The production of intermediate products has recovered, and the price of nickel salts has declined slightly. The inventory of electrolytic nickel is accumulating, and the upward pressure is significant. - Outlook: In the short term, nickel prices will fluctuate widely, and in the long term, they will face downward pressure [22]. 3.1.8 Stainless Steel - Viewpoint: With the cooling of sentiment, the stainless - steel market will fluctuate. - Information Analysis: The stainless - steel futures warehouse receipt inventory remained unchanged. SMM expects the HPM of Indonesian domestic trade ore to rise slightly in the first half of August. The spot price of 304 stainless steel in Foshan had a discount to the main contract. The average price of high - nickel pig iron remained unchanged [23][25]. - Main Logic: The price of nickel iron has stopped falling and rebounded, and the price of chrome iron is stable. Due to the traditional consumption off - season, the improvement in spot trading volume is limited. In June, stainless - steel production decreased month - on - month but remained at a high level, and there is a risk of weakening apparent demand. Last week, social inventory and warehouse receipts decreased, alleviating the structural surplus pressure. - Outlook: The overall sentiment in the commodity sector has cooled. Attention should be paid to the possibility of increased production cuts by steel mills due to long - term profit compression and policy expectations. In the short term, stainless - steel prices are expected to fluctuate within a range, and attention should be paid to inventory changes and cost - side changes [24]. 3.1.9 Tin - Viewpoint: With inventory accumulation in both markets, tin prices will fluctuate. - Information Analysis: On July 29th, LME tin warehouse receipt inventory increased by 35 tons to 1855 tons, and Shanghai tin warehouse receipt inventory increased by 160 tons to 7529 tons. The trading volume decreased by 2289 lots to 52135 lots. The average spot price of 1 tin ingots decreased by 2700 yuan/ton to 266100 yuan/ton [24]. - Main Logic: After the mining license is issued, tin ore production is expected to gradually increase, but the tight supply situation in China will not change in the short term. The supply - demand fundamentals provide strong support for tin prices. However, the terminal demand for tin has weakened marginally in the second half of the year, limiting the upward momentum of tin prices. - Outlook: With the tight supply of tin ore, tin prices have bottom support and are expected to fluctuate. In August, the volatility of tin prices may increase due to possible changes in macro, capital, and supply - demand factors [26]. 3.2行情监测 The report does not provide specific content for this part.
