1. Report Industry Investment Ratings No information about industry investment ratings is provided in the given reports. 2. Core Views Copper - The copper market presents a combination of "strong current situation + weak expectation". The short - term price is likely to fluctuate. The main contract price is expected to range between 77,500 - 79,500 yuan/ton. The macro - level factors and the uncertainty of demand in the peak season are the main influencing factors [1]. Aluminum - For alumina, the market is influenced by both positive and negative factors, and the price is expected to fluctuate in the short term. For electrolytic aluminum, the inventory reduction and the easing of tariff sentiment support the price, but the expected weakening of demand and the decline in cost put pressure on the price. The short - term price is likely to fluctuate [3]. Zinc - The short - term zinc price may be supported by the easing of tariff signals. In the future, the price may decline if terminal consumption is insufficient due to tariff policies, or maintain a high - level oscillation if the growth rate of the mining end is lower than expected and downstream consumption exceeds expectations. In the medium - to - long - term, a short - selling strategy is recommended, with the main contract price reference range of 21,500 - 23,500 yuan/ton [4]. Tin - The macro - sentiment improvement may drive the tin price to rebound, but considering the supply - side restoration and the pessimistic demand expectation, short - selling can be attempted in the range of 265,000 - 270,000 yuan/ton. Attention should be paid to the supply - side raw material restoration rhythm [7]. Nickel - The short - term nickel price is expected to fluctuate. The macro - sentiment has improved, and the cost provides some support, but the medium - term supply is expected to be loose. The main contract price is expected to range between 122,000 - 128,000 yuan/ton [8]. Stainless Steel - The stainless - steel market is expected to fluctuate. The raw - material end provides some support, but the short - term supply - demand contradiction has intensified, and the inventory pressure has slightly eased. The main contract price is expected to range between 12,600 - 13,200 yuan/ton [11]. Lithium Carbonate - The short - term lithium carbonate price is expected to show a weak oscillation. The supply pressure is obvious, the demand is relatively flat, and the inventory is still high. The main contract price is expected to range between 62,000 - 66,000 yuan/ton [14]. 3.

1. Report Industry Investment Ratings No investment ratings are provided in the reports. 2. Core Views of the Reports Tin - The current supply of tin ore remains tight, but the supply is expected to recover in July. The demand improvement is limited, and the subsequent demand outlook is pessimistic. The Sino - US tariff negotiation consensus may drive the price to rebound, but considering supply recovery and weak demand, try shorting in the 265,000 - 270,000 range and focus on the supply recovery rhythm [1]. Copper - Macroeconomic factors such as tariffs and the "232" investigation affect copper prices. The supply of raw materials is tight, and domestic inventories are low. The demand in the peak season may not be sustainable. The copper market shows a "strong current + weak expectation" pattern, with prices expected to be volatile in the short - term, and focus on the demand after May and tariff negotiation progress [2]. Aluminum - For alumina, the operating capacity may fluctuate, demand is stable with limited growth, and the cost support is weakening. Prices are expected to be volatile. For electrolytic aluminum, the supply is stable, demand may decline, but the low inventory and tariff relaxation support the price. Overall, the price is expected to be weak, with a support range of 18,000 - 18,500 [4]. Zinc - The supply of zinc ore is loose. Refined zinc supply was affected by over - expected maintenance in April. Downstream demand is weak, and the purchasing index is weakening. Short - term prices may be supported by tariff relaxation. In the long - term, consider shorting, and focus on ore production and downstream demand changes [6]. Lithium Carbonate - The futures market fluctuates. The tariff negotiation result has a short - term impact on sentiment. The supply pressure is clear, demand is relatively flat, and inventory is high. Prices may stabilize in the short - term, but the upside is limited. The overall strategy is to short on rallies, with a reference range of 62,000 - 66,000 [9]. Nickel - The nickel market is affected by the rumored Philippine ore ban and tariff negotiation results. The cost support is strong, but the medium - term supply is loose, restricting the upside. The price is expected to be in a range - bound adjustment, with a reference range of 122,000 - 128,000 [11]. Stainless Steel - The stainless - steel market is affected by tariff negotiation results. The ore price provides support, but the supply is excessive, and demand is slowly recovering. The inventory pressure eases slightly. The price is expected to be volatile, with a reference range of 12,600 - 13,200 [14]. 3.

Core Viewpoint - The article discusses the significant impact of U.S. tariffs on copper imports, initiated by former President Trump, which has led to dramatic fluctuations in copper prices and inventory movements in the global market [1][2][3]. Group 1: Tariff Implementation and Market Reactions - On February 10, 2025, Trump signed an executive order imposing a 25% tariff on all imported steel and aluminum, which quickly raised domestic prices [1]. - Following this, on February 26, the U.S. government extended tariffs to copper, marking it as a new battleground in the trade war [1][2]. - By March 4, the COMEX-LME copper price spread surged to $950/ton, prompting traders to transfer LME Asian inventories to the U.S., with a single-day drop of 9,050 tons in LME Asian inventory [1][2]. Group 2: Price Fluctuations and Inventory Changes - On March 13, copper prices soared to $5.25/pound (approximately $11,574/ton), a 25% increase from the 2024 average, while U.S. copper imports surged to 500,000 tons, far exceeding the normal level of 70,000 tons [2]. - LME copper inventory decreased by 12%, exacerbating supply-demand mismatches [2]. - After the unexpected exemption of copper products from tariffs on April 2, copper prices corrected downward, reaching a low of $8,105/ton amid fears of a global recession [2]. Group 3: Future Implications and Strategic Moves - The U.S. Department of Commerce is set to submit a report on copper tariffs by November 22, 2025, with a final decision expected by March 30, 2026, creating uncertainty in the copper market [3]. - As of May 12, COMEX copper inventory reached 163,400 tons, a six-year high, while LME inventory fell to 190,700 tons, indicating a significant shift in global copper stockpiles [3]. - The COMEX-LME price spread peaked at $1,643/ton on March 26, reflecting the market's volatility due to tariff uncertainties [3]. Group 4: Broader Economic Context - The article highlights the U.S. strategy to manipulate global copper trade through tariffs, aiming to force the return of copper-related manufacturing to the U.S. and curb China's copper industry growth [3][4]. - The relationship between U.S. manufacturing and copper prices is noted, with a strong correlation between China's manufacturing activity and copper prices, as China accounts for 56% of global refined copper consumption [6][7]. - The ongoing trade tensions and tariff strategies are seen as part of a broader effort by the U.S. to maintain its economic dominance amid rising competition from China [6][18].
