The finding marks a notable shift in the stablecoin competitive landscape, particularly given USDT's long-standing dominance in most major markets.Waidmann acknowledged that Tether's USDT continues to hold the top position globally by total holdings, but noted the gap between the two stablecoins is closing at a rapid pace.The data points to a potential geographical bifurcation in stablecoin preference, with USDC gaining ground in regulated Western markets where institutional adoption and compliance considerations may favor Circle's offering over Tether. USDT continues to dominate in emerging markets and regions where dollar access and transaction utility take precedence over regulatory profile.
