This year, the world commemorates the anniversaries of two key events in the development of the global monetary system. The first is the creation of the International Monetary Fund at the Bretton Woods conference 75 years ago. The second is the advent, 50 years ago, of the Special Drawing Right (SDR), the IMF’s global reserve asset.
When it introduced the SDR, the Fund hoped to make it “the principal reserve asset in the international monetary system.” This remains an unfulfilled ambition; indeed, the SDR is one of the most underused instruments of international cooperation. Nonetheless, better late than never: turning the SDR into a true global currency would yield several benefits for the world’s economy and monetary system.
The idea of a global currency is not new. Prior to the Bretton Woods negotiations, John Maynard Keynes suggested the “bancor” as the unit of account of his proposed International Clearing Union. In the 1960s, under the leadership of the Belgian-American economist Robert Triffin, other proposals emerged to address the growing problems created by the dual dollar-gold system that had been established at Bretton Woods. The system finally collapsed in 1971. As a result of those discussions, the IMF approved the SDR in 1967, and included it in its Articles of Agreement two years later.
