Since the outbreak of the financial crisis in 2008 Keynes's proposal has been revived: In a speech delivered in March 2009 entitled Reform the International Monetary System, Zhou Xiaochuan, the governor of the People's Bank of China called Keynes's bancor approach "farsighted" and proposed the adoption of International Monetary Fund (IMF) special drawing rights (SDRs) as a global reserve currency as a response to the financial crisis of 2007–2010. He argued that a national currency was unsuitable as a global reserve currency because of the Triffin dilemma—the difficulty faced by reserve currency issuers in trying to simultaneously achieve their domestic monetary policy goals and meet other countries' demand for reserve currency.[5][6] A similar analysis can be found in the Report of the United Nation's "Experts on reforms of the international monetary and financial system"[7] as well as in the IMF's study published on 13 April 2010.[8]
