There is a big difference between the futures price and the spot price. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts based on commodities such as cotton, soybeans and oil, as well as standardized tradable contracts for financial assets such as stocks and bonds. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments. Futures can be delivered in a week, a month, three months or even a year. A contract or agreement to buy or sell futures is called a futures contract. The place where futures are traded is called the futures market. Investors can invest or speculate in futures. The background of China futures market is the reform of grain circulation system. With the cancellation of the policy of unified purchase and marketing of agricultural products and the liberalization of most agricultural products prices, the market is playing an increasingly important role in regulating the production, circulation and consumption of agricultural products. The price fluctuation of agricultural products, the secrecy distortion of spot prices, the fluctuation of agricultural production and the lack of hedging mechanism of grain enterprises have attracted the attention of leaders and scholars. Whether we can establish a mechanism that can not only provide price signals to guide future production and business activities, but also prevent market risks caused by price fluctuations has become the focus of attention. The market price refers to the market price. It also refers to the rise and fall of interest rates or exchange rates in financial markets.
