Special Drawing Rights (SDR) refers to an asset created by the IMF to help bolster member countries' currency reserves. When it was initially created in 1969, each SDR was worth 0.88671 grams of fine gold. Today, the IMF adjusts SDR valuation every five years using a basket of fixed conversion rates with the dollar, euro, yuan, yen, and pound sterling. SDRs can be exchanged with member countries for these currencies.
