Special Drawing Rights:

The Special Drawing Rights (SDR) was created by the IMF in 1969 to support the Bretton Woods fixed exchange rate system and a part of a country's foreign reserves. A country participating in this system needed official reserves government or central bank holdings of gold and widely accepted foreign currenciesthat could be used to purchase the domestic currency in foreign exchange markets, as required to maintain its exchange rate. The SDR is neither a currency, nor a claim on the IMF. Rather, it is a potential claim on the freely usable currencies of IMF members. Holders of SDRs can obtain these currencies in exchange for their SDRs in two ways: first, through the arrangement of voluntary exchanges between members; and second, by the IMF designating members with strong external positions to purchase SDRs from members with weak external positions. In addition to its role as a supplementary reserve asset, the SDR, serves as the unit of account of the IMF and some other international organizations. The value of the SDR was initially defined as equivalent to 0.888671 grams of fine gold which, at the time, was also equivalent to one U.S. dollar. After the collapse of the Bretton Woods system in 1973, however, the SDR was redefined as a basket of currencies, today consisting of the euro, Japanese yen, pound sterling, and U.S. dollar. IMF members often need to buy SDRs to discharge obligations to the IMF, or they may wish to sell SDRs in order to adjust the composition of their reserves. The IMF acts as an intermediary between members and prescribed holders to ensure that SDRs can be exchanged for freely usable currencies. For more than two decades, the SDR market has functioned through voluntary trading arrangements. Under these arrangements a number of members and one prescribed holder have volunteered to buy or sell SDRs within limits defined by their respective arrangements. Following the 2009 SDR allocations, the number and size of the voluntary arrangements has been expanded to ensure continued liquidity of the voluntary SDR market.
