The US dollar is still the most stable, most widespread reserve currency and as long as they are the biggest global economy they will have the most physical money in circulation, making the US dollar a sensible reserve currency. No other currency is stable or widespread to the same level and technological alternatives are currently both less stable and less widely used. Debt bonds is what are traded now, not US dollars, but bonds are paid in US dollars because of trust in the currency, this trust has allowed America to monetise debt and issue debt bonds a lot more quickly than any other country or currency, and this is unlikely to change. Do you think the dollar is likely ton be replaced ?
