A major advantage of an SDR-based system is that it would provide a mechanism for the IMF to provide finance with its own resources in an agile way during crises, thus operating in the same way as central banks have been doing on a massive scale in recent months. It would also be a much better mechanism with which to finance the IMF during crises than the credit lines to the IMF from a few countries (“arrangements to borrow”) that the G-20 is again advocating, as it is truly multilateral financing that does not depend on any individual country.
