Key conclusions

• Mastercard is integrating stablecoins into its payments infrastructure to modernize its back-end settlement process, enabling banks and issuers to settle card transactions using regulated digital dollars such as SoFiUSD.

• The partnership with SoFi Technologies enables SoFi Bank to settle Mastercard transactions in SoFiUSD, while the Galileo platform allows other banks and fintech issuers to accept stablecoin settlement.

• Stablecoin settlements focus on the post-transaction settlement stage, which means consumers will continue to exploit cards as normal, while basic settlements between banks can take place via blockchain-based digital assets.

• Using the Multi-Token Network (MTN), Mastercard aims to support multiple forms of tokenized money, including stablecoins, tokenized deposits and digital representations of fiat currencies.

Stablecoins are increasingly moving beyond the cryptocurrency niche and into mainstream financial discussions. A perfect example is Mastercard’s move to incorporate stablecoins into its card payment settlement process. Instead of abandoning the classic card model, Mastercard is simply modernizing its back-end infrastructure with regulated digital dollars.

Working with SoFi Technologies, the payments giant is testing how these digital assets can improve transaction settlement across its immense network. This initiative signals that the world’s largest payment railways are preparing for a future in which classic banking and digital assets exist side by side.

SoFiUSD Partnership

Mastercard’s latest initiative includes: cooperation with SoFi Technologies, which introduced a dollar-backed stablecoin called SoFiUSD.

Pursuant to this arrangement, SoFi Bank, NA intends to exploit SoFiUSD to settle Mastercard credit and debit card transactions. Meanwhile, SoFi’s payments infrastructure platform, Galileo Financial Technologies, will enable banks and fintech issuers on its network to choose to settle stablecoins through the Mastercard system.

SoFiUSD is issued by a domestically licensed U.S. bank and reportedly maintains a 1:1 cash reserve structure, placing it closer to bank-issued digital money than a typical crypto asset.

Did you know? The first credit card to gain wide acceptance across many merchants was the credit card fired by Diners Club in 1950. Cardholders originally received paper statements and paid their bills monthly, laying the foundation for today’s global card payment networks.

Understanding card settlements

Mastercard’s approach makes more sense when you understand how card payments typically work. When a consumer taps or swipes his card, the following steps are performed:

1. Payment is authorized.

2. The transaction is recorded.

3. The seller receives confirmation.

4. Issuing and acquiring banks settle at a later stage.

This final settlement phase traditionally takes place through conventional banking channels during designated settlement windows.

Mastercard’s stablecoin strategy specifically targets this back-end settlement process. This doesn’t change how users experience or initiate payments. From the buyer’s point of view, the payment process would remain unchanged.

How stablecoin settlement would work

By settling in stablecoins, the Mastercard network will enable participating banks and issuers to fulfill transaction obligations using a digital dollar, rather than relying solely on classic fiat transfers.

In practice, this process could go as follows:

• The customer initiates a card payment in his or her local currency.

• Mastercard determines the settlement obligations between the issuing bank and the acquiring bank.

• Instead of relying solely on conventional banking channels, one or both parties can settle using stablecoins such as SoFiUSD.

Because stablecoins run on blockchain infrastructure, they offer 24/7 settlement capabilities, regardless of classic banking hours.

This method could reduce delays in cross-border payments and improve the liquidity management of financial institutions.

Did you know? The term “stablecoin” has become popular 2014but the concept of digital dollars backed by real-world assets was explored even earlier in experimental crypto projects that aimed to maintain price stability through security and algorithmic mechanisms.

The role of the Mastercard multi-token network

The core of this initiative is Mastercard’s Multi-Token Network (MTN). It is designed to support many forms of tokenized money, including:

By combining conventional banking systems with blockchain-based tokens, Mastercard seeks to create a comprehensive settlement ecosystem where regulated digital assets can operate alongside classic financial infrastructure.

The network would enable financial institutions to transfer value more efficiently while adhering to established regulatory standards.

Why Mastercard is entering the stablecoin market

Stablecoins have become one of the fastest growing parts of the digital asset market in recent years. They combine the price stability of fiat currency with the speed and efficiency of blockchain technology. As a result, they can support swift transfers, programmable payments and almost instantaneous settlements across global networks.

By March 2026, the stablecoin market had achieved a significant milestone, with its total valuation rising to approximately $314 billion, according to DefiLlama data. This growth follows a landmark year in 2025, in which transaction volume reached a record $969.9 billion in a single month. Experts now forecast that monthly volumes will be on track to exceed $1 trillion by the end of 2026.

The inclusion of stablecoins in Mastercard’s settlement infrastructure helps ensure the company remains at the center of the evolving digital payments ecosystem.

Instead of competing with blockchain systems, Mastercard is positioning itself as a connector between classic finance and digital asset networks.

Going beyond uncomplicated payments

The partnership between SoFi and Mastercard also aims to explore additional financial applications for stablecoins.

Potential applications include:

• Cross-border transfers

• Business-to-business payments

• Treasury management tools

• Stablecoin related card programs

Stablecoins could enable companies to automate sophisticated financial flows through programmable transactions.

For example, companies could automatically release payments when contractual terms are met, reducing manual intervention costs and operational costs.

Competition from Visa

Mastercard is not alone among global card networks that is exploring stablecoin integration. Its main competitor, Visa, also did this expanded uses digital currencies to settle payments.

Visa has tested cross-border settlements using stablecoins such as USD Coin (USDC), allowing financial institutions to pre-fund international transfers with tokenized dollars. The company was also considering allowing companies to send payouts directly to stablecoin wallets.

These efforts suggest that stablecoins are becoming a key part of broader infrastructure competition among leading payment networks.

Why regulations will be key

The adoption of stablecoins in mainstream financial systems depends largely on regulation.

Financial institutions need a clear regulatory framework that addresses key issues, including:

Because SoFiUSD is issued by a regulated U.S. bank, it is likely to inspire greater confidence among regulators and financial institutions than stablecoins originating in the crypto space.

That’s why payment networks like Mastercard are prioritizing regulated stablecoins issued by licensed institutions.

Did you know? Global card payment systems process tens of billions of transactions every year, and card networks process thousands of payments per second during peak shopping periods such as Black Friday and major online retail events.

Challenges to widespread adoption

Despite growing interest, several challenges may limit wider adoption of stablecoin settlements.

These challenges include:

• Complexity of integration for banks and payment processors

• Regulatory differences across jurisdictions

• Managing liquidity between fiat and digital assets

• Interoperability between blockchains and financial networks

Moreover, consumers are unlikely to notice major changes because the technology mainly affects back-end infrastructure rather than front-end payments.

The bigger picture of digital payments

Mastercard’s stablecoin initiative is part of a broader transformation taking place in global finance. Stablecoins were initially used mainly for cryptocurrency trading. They are now increasingly seen as potential tools for payments, remittances and wider financial infrastructure.

If stablecoin settlement proves proficient and reliable, card networks could eventually operate as a hybrid system that combines classic banking rails with blockchain-based digital assets.

Mastercard does not intend to replace classic payments. Rather, it is modernizing the hidden infrastructure of global card networks. By integrating regulated stablecoins like SoFiUSD into its Multi-Token network, the company is preparing its infrastructure for a more digital economy.

The goal is to create a system that is faster, more versatile and available 24/7, while ensuring that the average shopper won’t notice any difference at checkout.
