The international monetary system: evolution and revolution

Since the collapse of the Bretton Woods system in 1973, evolution has been the defining feature of changes in the IMS. The IMS has always been dominated by the US dollar. With it comes four structural issues: imbalance, lack of coordination, inade quacy, and weaponization of financial infrastructure. The Russia-Ukraine conflict will further accelerate the diversification and fragmentation of the IMS. But it might also lead to revolutionary changes such as balkanization of the IMS and even the end of financial globalization. Diversification of reserve currency could alleviate the imbalance and inadequacy problems of the IMS, restraining the dollar weaponization to some extent, but could not solve the problem of incoordination. Without a fair and inclusive IMS, ever larger financial spillovers will come from center countries to peripheral ones, and the global economy and financial system will face greater challenges in both efficiency and stability.
