Generally speaking, after the financial crisis, the price of copper and other commodities fell due to insufficient demand. For example, in the post-crisis recovery process, the infrastructure construction in Daxing, China will promote the demand for copper, which will increase in stages.
In addition, after the crisis, international hot money will choose currencies with high credit ratings and their bonds for investment, and the US dollar is the first choice. International copper prices are priced in dollars, and the rise of dollars will lead to the decline of copper prices. However, when the international community has doubts about the economic recovery in the United States, it will throw out dollars, and the decline of the dollar will lead to the rise in the prices of commodities such as copper.
