While the G-20 leaders have decided to support an SDR allocation of $250 billion, this will increase the share of SDRs in total international reserves to no more than 4%. In order to make the SDR the principal reserve asset via the allocation route, close to $3 trillion in SDRs would need to be created, an unrealistic proposition.
如果在IMF的成员国中大量地推出以SDR为基础的交易，SDR的地位将会逐渐加强，在近期的20国峰会上，参会的领袖们决定推出2500亿SDR的金融方案，这将SDR在国际金融储备市场的份额增加到了4%。如果SDR要成为市场的主要货币的话，市值至少要到3万亿SDR，现在看来这种可能性不大。
