Which currencies dominate global payments?

Swift is a globally integrated financial messaging network that connects more than 11,500 institutions across over 200 countries and territories. Its pivotal role in facilitating cross-border transactions underscores the enduring dominance of the US dollar in the international monetary system—a supremacy rooted in the 1944 Bretton Woods Agreement, which loosened the tie between gold and currency and cemented the dollar as the world’s leading reserve currency.
