Special Drawing Rights (ISO 4217 currency code XDR, also abbreviated SDR) are supplementary foreign - exchange reserve assets defined and maintained by the International Monetary Fund (IMF). The XDR is the unit of account for the IMF, and is not a currency per se. XDRs instead represent a claim to currency held by IMF member countries for which they may be exchanged. The XDR was created in 1969 to supplement a shortfall of preferred foreign - exchange reserve assets, namely gold and the U.S. dollar.
