The leverage of each futures product is different. For example, the margin rate of commodity futures is generally 8%- 15%, and the corresponding leverage is 6- 15 times. The leverage of stock index futures in financial futures is 5 times, the leverage of treasury bonds futures can reach 50 times, and the leverage of crude oil futures can reach 20 times. The calculation method of leveraged futures is 1÷ margin. For example, if the margin ratio of commodity futures is 15%, then the futures leverage is 1÷ 15%=6.67 times. It is worth mentioning that many futures companies control the leverage ratio of accounts in order to prevent and control risks when opening accounts.

The leverage effect in finance, that is, the financial leverage effect, refers to the phenomenon caused by the existence of fixed fees. When a financial variable changes in a small range, another related variable will change in a large range. That is to say, when enterprises adopt debt financing methods (such as bank loans, issuing bonds and preferred shares), the change rate of earnings per share of common stock is greater than that of earnings before interest and tax. Because the financial expenses such as interest expense and preferred stock dividend are fixed, when the income before interest and tax increases, the fixed financial expenses per common stock will decrease relatively, thus bringing additional income to investors.
