Financial derivatives usually refer to financial instruments derived from basic assets. Because many financial derivatives transactions have no corresponding subjects on the balance sheet, they are also called "off-balance sheet transactions". The same characteristic of financial derivatives is margin trading, that is, as long as a certain proportion of margin is paid, the full amount can be traded without the actual principal transfer, and the contract is generally settled by cash spread. Only contracts performed by physical delivery on the due date require the buyer to pay all the loans. Therefore, financial derivatives trading has leverage effect.
Soybean futures are also financial derivatives.
