First, the International Monetary Fund is a tool for the United States to achieve economic expansion and establish dollar hegemony. Through the economic strength accumulated during World War II, the United States established the IMF and had absolute control over it. Through the provisions of the International Monetary Fund agreement, an international monetary system centered on the US dollar has been established, and the hegemonic position of the US dollar in the world has been established. To some extent, the International Monetary Fund has become a tool for the United States to implement its expansion policy, especially in the early post-war period. However, after the 1960s, the use of this tool in the United States was increasingly challenged by other countries.

Second, the implementation of the relevant provisions of the International Monetary Fund, especially the fixed exchange rate system, forced member countries to lift foreign exchange controls, which played a certain role in promoting the rapid development of international trade after the war.

Third, the loans granted by the International Monetary Fund have played a certain role in easing the balance of payments difficulties of member countries and stabilizing the exchange rates of member countries.
