The International Monetary Fund has three main functions: ①Establish the codes of conduct that member countries need to abide by in terms of exchange rate policies, payments related to current accounts, and currency convertibility, and implement supervision. Exchange rate supervision is an important function of the International Monetary Fund. Its purpose is to ensure orderly exchange arrangements and the stability of the exchange rate system, eliminate exchange controls that are not conducive to the development of international trade, and prevent member states from manipulating exchange rates or adopting discriminatory exchange rate policies. To seek unfair competitive benefits. It is opposed to member states using macroeconomic policies, export subsidies or any other means to manipulate exchange rates, and it is opposed to member states adopting differential exchange rate policies (such as dual exchange rates, multiple exchange rates, etc.). ② Provide necessary temporary financial facilities to member countries experiencing difficulties in the balance of payments so that they can comply with the above-mentioned code of conduct and avoid adopting economic policies that are not conducive to the economic development of other countries. ③ Provide a venue for member countries to conduct international monetary cooperation and consultation. As global economic integration increases and the economic interdependence of various countries increases, it is an important function of the International Monetary Fund to open a venue for consultation and cooperation on international monetary issues.
