IMF calls for dollar alternative

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.

Dominique Strauss-Kahn, managing director of the IMF, acknowledged there are some "technical hurdles" involved with SDRs, but he believes they could help correct global imbalances and shore up the global financial system. (more)
