Recently proposed (21st century)

On March 16, 2009, in connection with the April 2009 G20 summit, the Kremlin called for a supranational reserve currency as part of a reform of the global financial system. In a document containing proposals for the G20 meeting, it suggested that the "IMF (or an Ad Hoc Working Group of G20) should be instructed to carry out specific studies to review the following options:
Enlargement (diversification) of the list of currencies used as reserve ones, based on agreed measures to promote the development of major regional financial centers. In this context, we should consider possible establishment of specific regional mechanisms which would contribute to reducing volatility of exchange rates of such reserve currencies.
Introduction of a supra-national reserve currency to be issued by international financial institutions. It seems appropriate to consider the role of IMF in this process and to review the feasibility of and the need for measures to ensure the recognition of SDRs as a "supra-reserve" currency by the whole world community."[4][5]
On March 24, 2009, Zhou Xiaochuan, President of the People's Bank of China, called for "creative reform of the existing international monetary system towards an international reserve currency," believing it would "significantly reduce the risks of a future crisis and enhance crisis management capability."[6] Zhou suggested that the IMF's Special Drawing Rights (a currency basket comprising dollars, euros, yen, and sterling) could serve as a super-sovereign reserve currency, not easily influenced by the policies of individual countries. US President Obama, however, rejected the suggestion stating that "the dollar is extraordinarily strong right now." [7] At the G8 summit in July 2009, the Russian president expressed Russia's desire for a new supranational reserve currency by showing off a coin minted with the words "unity in diversity". The coin, an example of a future world currency, emphasized his call for creating a mix of regional currencies as a way to address the global financial crisis.[8]

On March 30, 2009, at the Second South America-Arab League Summit in Qatar, Venezuelan President Hugo Chavez proposed the creation of the Petro as a supranational currency, in order to face the instability that the generation of fiat currency has caused in the world economy.[9] The petrocurrency would be backed by the huge oil reserves of the oil producing countries
