For example, compared with ordinary futures trading, the cash-out period in futures is conducive to the smooth receipt of goods between management, processing and production enterprises, and saves the expenses of loading, unloading, sorting and packaging. Cash conversion can not only make production, management and processing enterprises avoid price risks, but also improve the efficiency of capital utilization. If the processing enterprises concentrate on delivery when the contract expires, they must spend a large sum of money to buy raw materials at one time. Installment payment can enable enterprises to buy back raw materials in batches according to processing needs, reduce capital pressure and reduce inventory. Production and operation enterprises can also receive funds for production in advance and in batches.
