There are many kinds of financial derivatives in the world, and more and more things belong to this category because of the continuous introduction of new varieties in financial innovation activities. Judging from the current basic classification, there are mainly the following three categories:

(1) can be divided into four categories according to product form: forward, futures, options and swaps.

(2) Classification by primary assets, namely, stocks, interest rates, exchange rates and commodities. If subdivided, stock categories include specific stocks (stock futures, stock option contracts) and stock index futures and option contracts formed by stock combinations. Interest rates can be divided into short-term interest rates represented by short-term deposit rates (such as interest rate futures, interest rate forwards, interest rate options and interest rate swap contracts) and long-term interest rates represented by long-term bond rates (such as bond futures and bond option contracts); Currency categories include the ratio between different currencies; Commodities include all kinds of bulk physical commodities.

(3) According to the transaction method, it can be divided into on-site transaction and off-site transaction. On-the-spot trading is usually called exchange trading, which refers to the trading mode in which all the supply and demand sides concentrate on the exchange for bidding trading. OTC means that both parties directly become counterparties, and their participants are limited to customers with high credit.
