Over the past eight decades, the status of the United States as an economic and geopolitical superpower and the role of the US dollar as the world’s dominant currency have reinforced each other. As a synonym for the dollar’s preeminent role in international currency transactions and foreign reserve holdings, dollar dominance has long been associated with the United States’ exorbitant privilege to finance large fiscal and current account deficits at low interest rates. This has helped the United States run a large defense budget and conduct extensive military operations abroad. In turn, the United States has used its military capabilities to support the free flow of goods and capital across the globe, boosting global growth while providing investors with confidence that investments in US financial instruments are secure. This virtuous cycle contributed to the long-lasting stability of the post-World War II international order, leading to a sustained rise in economic welfare in the United States and around the world.
