The International Monetary Fund (IMF) is an organization of 188 countries that works to foster global monetary cooperation and financial stability. It aims to facilitate international trade, promote employment and economic growth, and reduce poverty. The IMF manages a reserve asset called Special Drawing Rights (SDRs) that can supplement its members' official foreign exchange reserves. SDRs are allocated to IMF members in proportion to their quotas and can be exchanged for freely usable currencies. The value of SDRs is based on a basket of currencies and is recalculated every five years by the IMF.
