NEW YORK (CNNMoney) -- 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.

"Over time, there may also be a role for the SDR to contribute to a more stable international monetary system," he said.

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.

Oil prices usually go up when the dollar depreciates. Supporters say using SDRs to price oil on the global market could help prevent spikes in energy prices that often occur when the dollar weakens significantly.

The dollar alternatives

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.

SDRs, he said, "will further diversify the system."
