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.
