SDR, or Special Drawing Rights, is a type of international reserve asset created by the International Monetary Fund (IMF) to supplement the existing official reserves of member countries. It is a basket of currencies that includes the US dollar, euro, Chinese yuan, Japanese yen, and British pound, and is used as a unit of account for international transactions. SDRs are not a currency themselves, but rather a tool for countries to manage their foreign exchange reserves and promote global financial stability. They are allocated to member countries based on their IMF quotas and can be exchanged for freely usable currencies when needed. SDRs play a crucial role in the international monetary system and are often used as a measure of a country’s economic strength and stability.
