The financier of the Bretton Woods system from inception until now is the United States. The United States offered to run perpetual deficits and open its domestic markets in exchange for managing the defense policies of its allies to confront the Soviet Union. Since the collapse of the Soviet Union, the United States has started piece by piece to walk away from the Bretton Woods agreement.
No new agreement without the United States to finance it, protect it with its Military, and to guarantee it with its institutions' strength is viable. Since the United States is reverting to its historical position of isolationist strength, expect this to go nowhere. Gold will remain a safe haven but never again will it be the world reserve standard.
