Foreign exchange banks are the most important participants in the foreign exchange market. In the United States, more than a dozen large commercial banks located in new york and dozens of other major cities actually act as "market makers". Because they often buy and sell various currencies on a large scale in the foreign exchange market, the foreign exchange market can be formed and run smoothly.

In addition, the strength and seriousness of foreign exchange management laws and regulations implemented by designated foreign exchange banks in handling foreign exchange settlement and sale business will directly affect the smooth operation of the foreign exchange market and have a significant impact on the balance of payments. Therefore, on the one hand, the designated foreign exchange banks should strengthen the awareness of law-abiding and compliance management, strengthen internal management, and promote the healthy development of their foreign exchange business on the premise of compliance with laws and regulations; On the other hand, it is necessary to strengthen communication with the foreign exchange bureau, give timely feedback and further improve various foreign exchange management policies and regulations.
