Copper can be divided into brass and red copper. The current price of brass in bulk transactions is 13 yuan per catty, and that of red copper is about 20 yuan per catty. The price of scrap copper in the market is unstable. The main reasons include: factors of regional differences and factors of various types of copper. Types of copper include fired wire, motor copper, brass copper, white copper, bronze, pure copper, aluminum brass, etc. The valuation is based on the quality of the copper. Spot copper prices fluctuate due to market factors such as international and domestic futures, and prices vary daily.

1. Copper stock prices

1. Shanghai copper fluctuated within a narrow range during the day, and the market recovered slightly, but it still closed down 0.07%, and the center of gravity of futures prices shifted slightly downward. Copper inventories on domestic and foreign exchanges continue to be reduced, providing solid support for copper prices. However, the atmosphere for industrial products is still hardly optimistic, and copper prices are unlikely to perform well. Copper concentrate processing fees continued to rise in the latest week, currently rising to above US$62/ton. According to SMM, the fundamentals of raw materials have not changed much. Overland transportation continues to interfere with the transportation of copper concentrate in the northwest region, and shipping in Africa remains slow. In terms of inventory, the LME copper inventory is still being depleted at a relatively fast pace. Registered warehouse receipts have rebounded from a low level, but the extent is still limited, and the proportion of write-offs has fallen. Weekly copper inventories on the Shanghai Stock Exchange continued to decline, continuing to hit a more than 12-year low, but the decline narrowed. Copper domestic and foreign inventories continue to decline, with spot premiums remaining at around 400. Downstream prices are generally stable. Spot supply may be subject to voltage restrictions, and we are waiting for the inflection point to replenish inventories. Taken together, although low domestic and foreign inventories continue to support the bottom of copper prices, copper prices do not have the conditions for a sharp rise, so short-term copper prices may return to a volatile range.

2. Copper: Copper prices fluctuated during the day, and the LME spot premium shrank significantly after hitting a historical record. Domestic restrictions on goods have suppressed market sentiment. The early rise in copper prices was supported by global energy tensions and low domestic inventories. Power shortages not only occur in China, but also in Europe. Not only did LME inventories decline, domestic stock exchange inventories were also at low levels, and the State Reserve sold limited quantities. Some surveys show that copper production is affected by power restrictions, while power grid investment rebounds month-on-month. Short-term copper prices may continue to adjust. It is recommended to pay attention to Chilean mine production, copper downstream operations, inventory and spot status.
