Bulk commodities refer to material commodities that can enter the circulation field, but are not retail links, and have commodity attributes and are used in industrial and agricultural production and consumption for large-scale transactions. In the financial investment market, bulk commodities refer to commodities that are homogeneous, tradable, and widely used as basic industrial raw materials, such as crude oil, nonferrous metals, agricultural products, iron ore, coal, etc. Commodities include three categories, namely energy commodities, basic raw materials and bulk agricultural products. Commodities can be designed to be traded as futures and options as financial instruments, which can better realize price discovery and avoid price risks. Since bulk commodities are mostly industrial bases and are at the most upstream, changes in futures and spot prices that reflect their supply and demand conditions will directly affect the entire economic system. For example, rising copper prices will increase production costs in the electronics, construction and power industries, while rising oil prices will lead to higher prices for chemical products and drive up the price and supply of other energy sources such as coal and alternative energy sources. Investors, especially those in investment-related industries, should pay close attention to the supply, demand and price changes of commodities.
