The global economic recession and the downturn in the real estate and automobile industries have caused the price of non-ferrous metals to "dive from the high platform", the prices of alumina and electrolytic aluminum have dropped by about 50%, and the highest price of copper has dropped by about 70%. The inventory of major non-ferrous metal production enterprises has increased rapidly, the benefits have declined seriously, the liquidity is extremely tight, and the scope of production reduction has been expanding.
The current era is characterized by rising financial attributes, global layout, national strategic reserve of important materials and constant adjustment of market structure. Recently, the price of non-ferrous metals fluctuates frequently, and the mutual restraint of multiple factors determines its weakness. On the one hand, the world economy has returned to the rising cycle, demand has recovered, and inventories have declined; On the other hand, the European sovereign debt crisis triggered a new round of worries, and the US dollar index rebounded strongly. In this context, the financial attributes of non-ferrous metals rapidly affect the market price. After entering the industrialized society, spot and futures co-exist in the major nonferrous metals markets such as copper. The explosion of global informatization has made the prices in various regions more transparent in real time, which has provided a decisive basis for nonferrous metal futures to become a typical derivative financial commodity. At present, the price trend of major non-ferrous metals in domestic and foreign markets has not fully reflected the relationship between supply and demand. Changes in exchange rates, interest rates and tax rates of major countries in the world often have greater impact on their prices than changes in supply and demand. Currency liquidity determines the basic trend of the market price of non-ferrous metals.
