IMF paper by Isabelle Mateos y Lago, Rupa Duttagupta, and Rishi Goyal
The current system has its flaws, including occasionally bouts of serious instability, but it also has proved its strength and resilience when the conceivable alternatives have not. As the pressure points in current arrangements are better understood, so the remedies become clearer—a more stable center, stronger policy
frameworks in the periphery countries, and of course less volatile capital flows. These remedies must be pursued, but counting on them alone to achieve lasting stability would be assuming the problem away.
Executive Summary
The global crisis resurrected deep-rooted concerns about the functioning of the international monetary system (IMS). Despite its relative stability, the current “non-system” has the inherent weaknesses of a setup with a dominant country-issued reserve currency, wherein the reserve issuer runs fiscal and external deficits to meet growing world demand for reserve assets and where there is no ready mechanism forcing surplus or reserve-issuing countries to adjust. The problem has amplified in recent years in line with a sharp rise in the demand for reserves, reflecting in part emerging markets’ tendency to self-insure against costly capital account crises. This paper considers options to address these tensions, thereby contributing to the ongoing debate on strengthening the international monetary system. On the demand side, it explores alternative insurance arrangements that could mitigate the precautionary demand for reserves. On the supply side, it assesses a menu of alternative reserve assets that could offer sustained stability and efficiency. Many of the proposals presented would require fundamental changes in the forms and degree of international cooperation, but may gain realism and practical relevance if more incremental efforts at strengthening the current system fail.
