From Colombia to Vietnam and beyond, the US dollar is the currency in which much of international business is conducted, and which many people outside the US use as a means of exchange and a store of value.

When the position of the US dollar as the linchpin of global commerce was confirmed at the end of the Second World War, not everyone was happy with this state of affairs: the French soon spoke of the Americans having an ‘exorbitant privilege’. Did they have a point? And what of the more recent efforts to replace the Greenback with other currencies?
