宏观氛围回暖，铜强铝弱

Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Views - Copper: The macro - atmosphere has warmed up, and capital attention has increased. Last week, copper prices fluctuated upwards, with the main contract price once reaching the 79,000 - yuan mark on Thursday. The rise is due to the easing of Sino - US relations and financial attribute - driven catch - up growth. However, after the holiday, the social inventory of electrolytic copper increased slightly, and the spread between July and August contracts continued to narrow, pressuring the futures price. In the short term, the warming macro - atmosphere will drive copper prices to fluctuate upwards. Looking ahead to June, there are signs of a recovery in the macro - level [3][60]. - Aluminum: The macro - atmosphere has warmed up, but capital attention has decreased. Last week, aluminum prices fluctuated around the 20,000 - yuan mark with a narrowing amplitude and a decline in open interest. Trump's statement on May 30 to raise steel and aluminum tariffs to 50% may increase market tariff expectations and is bearish for aluminum prices in the long - term globally. In the short - and medium - term, the continuous increase in bauxite port inventory at the industrial upstream, good downstream demand, continuous depletion of electrolytic aluminum social inventory, and low downstream initial inventory support aluminum prices. It is expected that the futures price will maintain a volatile trend [4][60]. 3. Summary by Directory 3.1 Macro Factors - On the evening of June 5, Chinese President Xi Jinping had a phone call with US President Trump. Trump expressed respect for President Xi, and both sides recognized the importance of Sino - US relations. The Geneva economic and trade talks were successful. - The Chinese Vice - Premier He Lifeng will visit the UK from June 8 - 13 and will hold the first meeting of the Sino - US economic and trade consultation mechanism with the US [8]. 3.2 Copper - Volume and Price Trends: Last week, copper prices fluctuated upwards, with the main contract price once reaching the 79,000 - yuan mark on Thursday. Various price - related charts such as copper futures price trends, copper's Shanghai - London ratio, and others are presented [3][10][11]. - Declining Copper Ore Processing Fees: Since January, copper ore processing fees have been continuously decreasing, indicating a tight copper ore supply and over - capacity in smelting. The domestic copper ore port inventory is similar to that of the same period last year, reflecting an expected tightness in the domestic ore end [24]. - Slowing Electrolytic Copper De - stocking: The de - stocking of electrolytic copper has slowed down, as shown by the trends of domestic electrolytic copper social inventory and overseas futures inventory [28][29]. - Downstream Initial Demand: The monthly capacity utilization rate of copper downstream industries is presented, including data on refined copper rods, copper tubes, copper bars, and copper strips [31][32]. 3.3 Aluminum - Volume and Price Trends: Last week, aluminum prices fluctuated around the 20,000 - yuan mark, with a narrowing amplitude and a decline in open interest. Multiple price - related charts such as aluminum price trends, aluminum's Shanghai - London ratio, and others are provided [4][33][34]. - Upstream Industry Chain: The port inventory of bauxite has been continuously increasing, and the price trend of alumina is also shown [45][46][49]. - Seasonal De - stocking of Electrolytic Aluminum: The overseas electrolytic aluminum inventory (LME + COMEX) and domestic electrolytic aluminum social inventory show a trend of change, indicating seasonal de - stocking [50][51]. - Downstream Initial Demand: The capacity utilization rate of aluminum rods and the processing fee and inventory of 6063 aluminum rods are presented [53][54][57]. 3.4 Conclusion - Copper: In the short term, the warming macro - atmosphere will drive copper prices to fluctuate upwards. In June, there are signs of a macro - level recovery. However, the industrial end is in the off - season, with poor consumption expectations and rising inventory, which will put pressure on copper prices [3][60]. - Aluminum: The futures price is expected to maintain a volatile trend. In the long - term, Trump's tariff increase statement is bearish for aluminum prices globally, but in the short - and medium - term, the increase in upstream bauxite inventory, good downstream demand, and low downstream inventory support aluminum prices. If the domestic macro - situation continues to improve, aluminum prices will show a stronger volatile trend [4][60].
