Does the SDR have a role to play in the future evolution of the IMS, either as a complement to the existing reserve instruments or, in a longer-term perspective, as a forerunner of a true global currency on which the IMS could be centered? –  At present, the role of the SDR is very limited.
Allocated SDRs cannot be used directly to conduct interventions. More than a true reserve asset, they are a tool for redistributing reserves, for countries that cannot borrow them on the market. There is strong resistance to expanding the SDR’s role on the part of several IMF member countries. The SDR is seen as an unconditional form of credit, giving rise to moral hazard.
