In any case, dedollarisation is happening whether some people or even US itself accepts it or not. It didn't start last year and it won't mature soon but it is happening.
And after covid times dedollarisation became even stronger and faster, I think. The very idea of the dollar as a world leader rested on globalization, the blurring of borders between countries, especially the Western type of development states. The pandemic has contributed to a return to closed structures, both public and private. Localization is back again. Countries were forced to adjust their economies within themselves, often without the support of export. And because of this, they were forced to rely on their own tools. I think this trend will only continue, because the globalization of the world shows its inability.
