Stablecoins have quietly become a crucial component of global financial infrastructure, with transaction volumes surpassing $33 trillion in 2025, marking a 72% increase from the previous year. This surge highlights the shift from market cap focus to velocity, as stablecoins are increasingly used for settlements, payments, and treasury functions. Latin America, in particular, has embraced stablecoins as a hedge against local currency volatility, with Argentina and Brazil leading in on-chain activity. As stablecoins integrate into financial systems, issuers, exchanges, and custodial services are capturing significant revenue through reserve management and transaction fees. Tether, for instance, has become one of the most profitable companies per employee. The ongoing challenge lies in aligning incentives to ensure that users, who drive economic activity, also benefit from the value generated by stablecoin transactions. The evolution of stablecoins into invisible infrastructure marks a new era in digital finance, with the focus now on who will control and profit from this burgeoning ecosystem.
