Last week, the London Metal Exchange’s copper market rebounded strongly after the early period of sharp decline. It rose for four consecutive trading days. Inventory decreased, spot premium continued to expand, the US dollar weakened, and technical and consumer buying provided support for copper prices. Due to the uncertainty of the future trend of copper prices, market transactions were cautious and transactions were light. Last week, copper market in Shanghai was encouraged by higher copper prices. The overall price of the copper market showed moderate upward trend. At present, domestic copper supply is still tight and the spot premium is relatively large, which provides impetus for Shanghai copper prices to rise. However, copper consumption may become weaker in the future, and the uncertainty in the market will increase. The main 0507 contract closed at 31,160 yuan/ton on Friday, up 390 yuan from last Friday's close. In the week, the cumulative turnover of contracts reached 592,000, with a turnover of 90.76 billion yuan. Last week, the international aluminum market followed the trend of copper, supported by the continuous decline in LME aluminum inventories. The three-month aluminum price also rose for four consecutive trading days. Last week, Shanghai's aluminum market oscillated in a narrow range. At present, domestic supply is sufficient, resulting in weaker Shanghai aluminum prices, while high production costs and other factors limit the space for aluminum prices to fall, the price volatility is limited, and market participation is not enthusiastic. Trading volume was light. The main 0507 contract closed at 16,700 yuan / ton last Friday, up 20 yuan from last Friday's close. A total of 39,000 hand contracts were sold in the week, with a turnover of 3.29 billion yuan.
