Robert Triffin at the beginning of the 1960s warned that the Bretton Woods system (BWS) was unsustainable due to the inability of the reserve currency issuer to run current account deficit and surplus at the same time. Both were necessary to provide, respectively, international liquidity and trust in the status of the reserve currency. Contradictionary character of the dilemma finally led to the collapse of the BWS. Even though the contemporary system is entirely different in nature, the dilemma still applies. Vast accumulation of dollar reserves undermines confidence in the US fiscal capacity to repay its debt. Therefore, it is crucial to promote international cooperation and evolution towards a multipolar system, or system based on one supranational currency.
