A country in severe financial trouble, unable to pay its international bills, poses potential problems for the stability of the international financial system, which the IMF was created to protect. Any member country, whether rich, middle-income, or poor, can turn to the IMF for financing if it has a balance of payments need—that is, if it cannot find sufficient financing on affordable terms in the capital markets to make its international payments and maintain a safe level of reserves.

IMF loans are meant to help member countries tackle balance of payments problems, stabilize their economies, and restore sustainable economic growth. This crisis resolution role is at the core of IMF lending. At the same time, the global financial crisis has highlighted the need for effective global financial safety nets to help countries cope with adverse shocks. A key objective of recent lending reforms has therefore been to complement the traditional crisis resolution role of the IMF with more effective tools for crisis prevention.
