The International Monetary Fund issued a report Thursday on a possible replacement for the dollar as the world's reserve currency. The IMF said Special Drawing Rights, or SDRs, could help stabilize the global financial system. SDRs represent potential claims on the currencies of IMF members. They were created by the IMF in 1969 and can be converted into whatever currency a borrower requires at exchange rates based on a weighted basket of international currencies. The IMF typically lends countries funds denominated in SDRs While they are not a tangible currency, some economists argue that SDRs could be used as a less volatile alternative to the U.S. dollar. The goal is to have a reserve asset for central banks that better reflects the global economy since the dollar is vulnerable to swings in the domestic economy and changes in U.S. policy. In addition to serving as a reserve currency, the IMF also proposed creating SDR-denominated bonds, which could reduce central banks' dependence on U.S. Treasuries. The Fund also suggested that certain assets, such as oil and gold, which are traded in U.S. dollars, could be priced using SDRs. Fred Bergsten, director of the Peterson Institute for International Economics, said at a conference in Washington that IMF member nations should agree to create $2 trillion worth of SDRs over the next few years.
