Core Viewpoint - Recent fluctuations in copper prices have shown a trend of initial decline followed by recovery, influenced by U.S. tariff policies and market sentiment [1][2].

Group 3: Copper and Scrap Price Dynamics - The price difference between refined copper and scrap copper has narrowed significantly, reaching a low of 450 yuan/ton in mid-April, the lowest since October 2023 [4]. - The decline in copper prices has led to reduced sales volumes from scrap copper holders, impacting production levels [4]. - Despite negative processing fees for imported copper concentrate, domestic smelting rates have increased, reaching 87.68% by the end of March [4]. Group 4: Consumption Trends - The operating levels of refined copper rod enterprises are higher than in previous years, primarily due to insufficient scrap copper production rather than increased end-user demand [5]. - Seasonal trends in the air conditioning industry suggest a potential decline in copper demand in May, as production enters a down cycle [5]. - The automotive sector is expected to see a seasonal uptick in May, but the actual demand may be limited due to prior fulfillment of needs through subsidies [6].

铜价接连上涨沪铜今天小幅回落 近期，沪铜期货主力合约整体经历了一轮明显的升势，并于3月26日创出年内新高。3月27日，国内沪铜期货有所调整主力合约下跌1.03%，报81560元/吨，但 年内累计涨幅仍超过10%。 铜价近期凌厉的涨势引起市场广泛关注。 LME铜期货也有类似的表现，COMEX铜期货的涨势则更为凌厉。行情数据显示，截至当地时间3月26日，LME铜期货主力合约年内累计涨幅也超过10%，而 COMEX铜期货主力合约3月以来累计涨幅约15%，年内累计涨幅则已达到约三成，价格已于近期创出历史新高。 对于近期铜价总体上涨的原因，中信期货研究所有色与新材料组资深研究员郑非凡在接受证券时报记者采访时认为，近期铜价强势上涨受到了供应端紧张、 需求端改善和政策扰动三个方面的强力推动。从供应端来看，全球铜矿供给仍然紧张，供应扰动频发，例如：3月25日嘉能可旗下的智利阿尔托诺特 （Altonorte）冶炼厂因熔炉故障停产，产能约34.9万吨，占据了不小的市场份额。而此次停产正值特朗普在全球范围内抢先征收潜在关税之际，其减产预计 会加剧全球精炼铜市场的供需紧张。同时，铜矿现货加工费（TC）持续下滑，目前已经降至负20美元 ...

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The US is about to impose copper and reciprocal tariffs, which will lead to a general decline in non - ferrous metals. However, the impact on different metals varies. For example, the market for copper will quickly adjust the price difference, and the upward trend of copper prices may be near the end [2]. - The alumina market is expected to be volatile. Although the number of alumina plant overhauls is increasing, the impact on monthly production is limited. There is a possibility of a marginal decline in alumina production capacity from April to May [5][8]. - The aluminum market is supported by strong domestic demand. Despite the expected tariff increase in the US, LME aluminum shows a narrow - range sideways movement. Domestic aluminum processing enterprises'开工 rate is rising, and the demand for aluminum profiles is expected to be boosted [14][17][18]. - The zinc market is in a state of range - bound oscillation. Although there is an expectation of a large increase in zinc ingot supply, the current inventory is relatively low, and domestic consumption is expected to be boosted by policies [21][23]. - The lead market is affected by factors such as high prices of waste batteries and changes in supply and demand. The price of lead is running at a high level, but the profit of secondary lead smelters is shrinking, and there is a certain willingness to reduce production [26][28]. - The nickel market is expected to be strong in the short - term. The price of nickel ore is expected to be firm due to concerns about policies and production shortages. However, in the medium - term, high prices may stimulate over - supply [31][32]. - The stainless - steel market is affected by raw material prices and demand. The price of NPI is relatively high, and the supply of 300 - series stainless steel is still tight, but the upward space is gradually narrowing [38][39]. - The tin market is in a state of high - level wide - range oscillation. The shortage of tin concentrate is intensified, but the possible resumption of production in Wa State may relieve the supply pressure to some extent in the future [44][48]. - The industrial silicon market is expected to decline. The rumor of joint production cuts by industrial silicon manufacturers is false, and the market is in a state of oversupply with weak demand [50][54]. - The polysilicon market is expected to be volatile. Although there is information about production cuts, the overall supply pressure is not large, and the market may be affected by factors such as inventory and demand expectations [56][58]. - The lithium carbonate market is expected to decline. The price of lithium carbonate may continue to fall due to factors such as a decrease in imported ore prices and weak demand [63][64]. 3.
