In foreign trade, improper choice of pricing currency will often cause losses. Choosing pricing currency to prevent risks is considered from three aspects: (1) using convertible currency as pricing currency. Convertible currency can be converted into other currencies at any time, which is convenient for risk transfer when exchange rate risk occurs;

(2) The principle of hard payment and soft payment. Strive to use hard currency (currency expected to appreciate) for pricing and settlement in export trade of export and loan capital, and strive to use soft currency for pricing and settlement in import and loan capital investment;

(3) Consider the changing trend of interest rate and exchange rate. When financing in the market, debt with low interest rate is not necessarily low-cost debt.
