The US dollar has been the predominant global reserve currency since the design of the Bretton Woods system after the second world war. Even the move from fixed exchange rates in the early 1970s did not challenge the greenback’s “exorbitant privilege”.

But given the increased weaponisation of the dollar for national security purposes, and the growing geopolitical rivalry between the west and revisionist powers such as China, Russia, Iran and North Korea, some argue that de-dollarisation will accelerate. This process is also driven by the emergence of central bank digital currencies that could lead to an alternative multipolar currency and international payment regime.
