Mastercard is taking a significant step toward modernizing global payment infrastructure by integrating regulated stablecoins into its card settlement process. The payments giant has partnered with SoFi Technologies to enable SoFi Bank, N.A. to settle its Mastercard credit and debit card transactions using SoFiUSD, a dollar-backed stablecoin issued by a nationally chartered US bank.
The initiative leverages Mastercard's Multi-Token Network (MTN), a platform designed to support various forms of tokenized money, including stablecoins, tokenized bank deposits, and digital representations of fiat currencies. Crucially, this integration targets the back-end settlement phase between banks and issuers, not the consumer-facing payment experience. Shoppers will continue to use cards normally, while the underlying settlement may occur using blockchain-based digital assets.
SoFi's payments infrastructure platform, Galileo Financial Technologies, will play a key role by allowing other banks and fintech issuers on its network to opt for stablecoin settlement through Mastercard's system. This method promises potential benefits like 24/7 settlement independent of traditional banking hours, reduced delays in cross-border payments, and streamlined liquidity management for financial institutions.
The move comes as the stablecoin market shows explosive growth. As of March 2026, the total stablecoin market valuation reached approximately $314 billion, with monthly transaction volumes projected to surpass $1 trillion by the end of 2026. Mastercard's strategy positions it as a connector between traditional finance and digital asset networks, rather than a competitor to blockchain systems.
Mastercard is not alone in this exploration. Its main competitor, Visa, has also tested cross-border settlement using stablecoins like USD Coin (USDC). This indicates a broader infrastructure competition among leading payment networks to incorporate digital currencies.
The partnership also aims to explore additional financial applications for stablecoins, including cross-border remittances, business-to-business payments, treasury management tools, and stablecoin-linked card programs. The adoption within mainstream finance, however, hinges on clear regulatory frameworks addressing reserve backing, redemption guarantees, and Anti-Money Laundering (AML) compliance.
