World reserve currency status follows the leader in manufacturing and trade. Maintaining dollar hegemony was never going to be feasible after de-industrialization, but short-sighted decisions like weaponizing SWIFT have accelerated its decline. As the dollar is gradually shunted out of world trade, the US will be less able to export its inflation abroad. The implications won’t be pretty.
For all of its current very high profile issues of uncertainty in the US, who would actually trust China in any way shape or form as an alternative? It’s a totalitarian state who has been jailing its wealthiest businesspeople on a whim, causing many to flee, and it’s about to embark on an invasion of its peaceful neighbor. Which part of any of that screams “that currency will be a stable place to store my money?”
Most of the Asian countries (except South Korea, Japan and Taiwan) and African countries. They’re already getting tons of investments and loans from China.
