Since World War II, the global currency landscape has remained relatively stable, with the U.S. dollar serving as the dominant currency. Using country-level SWIFT transaction data, our analysis confirms the importance of inertia, trade and financial linkages in shaping the currency landscape, consistent with existing studies. On geopolitical proximity, we find that closer proximity can boost the use of the euro and renminbi, notably among emerging market and developing economies, although the impact is rather muted in the full sample. The effect on RMB usage in the full sample is more pronounced during periods of heightened trade policy uncertainty. These findings suggest that in a more geoeconomically fragmented world, alternative currencies could play a greater role.
