Allium: stablecoin payments rose 45% YoY to $482B YTD through September 30, with transactions up 71% to 1.04B, while circulating supply grew just 0.4%

You can now spend stablecoins on cards from major networks like Visa and Mastercard, which was not previously the case.

Stablecoin payments have surged by 45% year-over-year, reaching $482 billion year-to-date through September 30, according to analytics firm Allium. Despite this significant increase in payment volume, the total circulating supply of stablecoins grew by a minimal 0.4% over the same period. The number of stablecoin transactions saw an even more dramatic rise, increasing by 71% to over 1.04 billion, indicating that existing stablecoins are being utilized more frequently. This growth is occurring as major payment processors like Mastercard, Visa, and Stripe are integrating stablecoin functionalities into their existing payment systems, enabling businesses to use digital dollars alongside traditional fiat currencies. Spending through stablecoin-linked cards also showed rapid expansion, growing tenfold year-over-year, with small purchases under $50 comprising the majority of this increase.

The divergence between soaring payment volumes and stagnant supply suggests that stablecoins are evolving beyond speculative assets to become functional mediums of exchange for everyday commerce. Major financial infrastructure providers are enabling this shift by integrating stablecoins directly into existing payment rails, making them accessible through familiar platforms like cards and bank transfers. This development implies a growing acceptance of digital dollars within traditional financial ecosystems, aiming to reduce friction and currency conversion costs for businesses and consumers alike.

This trend signals a maturing market where the focus is shifting from pure supply growth to the utility and integration of stablecoins into global money movement. The increased transaction frequency and the surge in card-based spending, particularly for smaller transactions, indicate a growing trust and adoption among end-users. As more businesses seek to embed digital currencies into their operational workflows without building separate infrastructure, stablecoins are positioned to become a key component of cross-border and multi-currency transactions.
