Special Drawing Rights (SDRs) International reserve assets created by the International Monetary Fund and allocated to its members to supplement existing reserve assets. They represent each holder's assured and unconditional right to obtain other reserve assets, especially foreign exchange. IMF cannot allocate SDRs to itself but receives them from members through various financial transactions and operations. The SDR can be used for a wide range of transactions and operations, including the acquisition of other members' currencies, the settlement of financial obligations, the making of donations, and the extension of loans. Forward as well as spot transactions may be conducted in SDRs. The SDR is the unit of account for the Fund. The value of the SDR is determined daily by IMF on the basis of a basket of currencies with each currency assigned a weight in the determination of that value.
