Mastercard decides to settle card payments using Stablecoins

Key takeaways

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

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

• Stablecoin settlement focuses on the post-transaction clearing stage, meaning consumers will continue to use cards as normal while the underlying settlement between banks can take place via blockchain-based digital assets.

• By leveraging its Multi-Token Network (MTN), Mastercard aims to support multiple forms of tokenized currency, including stablecoins, tokenized deposits, and digital representations of fiat currencies.

Stablecoins are increasingly moving beyond the crypto niche and into traditional financial discussions. A good example is Mastercard’s decision to integrate stablecoins into its card payment settlement process. Rather than abandon the traditional card model, Mastercard is simply improving the back-end infrastructure by introducing regulated digital dollars into the mix.

By partnering with SoFi Technologies, the payments giant is testing how these digital assets can streamline transaction settlements across its vast network. This initiative shows that the world’s largest payment channels are preparing for a future in which traditional banking assets and digital assets coexist.

The SoFiUSD partnership

Mastercard’s recent move involves a partnership with SoFi Technologies, which introduced a dollar-backed stablecoin called SoFiUSD.

As part of this agreement, SoFi Bank, NA intends to use SoFiUSD to settle its Mastercard credit and debit card transactions. Meanwhile, SoFi’s payments infrastructure platform, Galileo Financial Technologies, will enable banks and fintech issuers in its network to opt for stablecoin settlement through Mastercard’s system.

SoFiUSD is issued by a nationally chartered U.S. bank and would maintain a 1:1 cash reserve structure, positioning it closer to the bank-issued digital currency than a typical crypto-native asset.

Did you know? The first credit card to be widely accepted by many merchants was spear by Diners Club in 1950. Originally, cardholders received paper statements and paid their bills monthly, laying the foundation for today’s global card payment networks.

Understanding card payment

Mastercard’s approach makes more sense once you understand how card payments usually work. When a consumer presents or swipes their card, the following steps take place:

1. Payment is authorized.

2. The transaction is recorded.

3. The merchant receives a confirmation.

4. The issuing and acquiring banks finalize the settlement at a later stage.

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

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

How stablecoin settlement would work

Through stablecoin settlement, Mastercard’s network would enable participating banks and issuers to fulfill their transaction obligations using a digital dollar rather than relying solely on traditional fiat transfers.

In practice, the process could go as follows:

• A customer initiates a card payment in their 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.

Since stablecoins operate on blockchain infrastructure, they offer the possibility of 24/7 settlement, independent of the opening hours of traditional banks.

This method could reduce delays in cross-border payments and streamline liquidity management for financial institutions.

Did you know? The term “stablecoin” has become popular 2014but the concept of digital dollars backed by real-world assets had been explored even earlier in experimental crypto projects that attempted to maintain price stability using collateralization mechanisms and algorithms.

The role of Mastercard’s multi-token network

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

By connecting conventional banking systems with blockchain-based tokens, Mastercard seeks to create a versatile settlement ecosystem in which regulated digital assets can operate alongside traditional financial infrastructure.

The network would allow financial institutions to transfer value more efficiently while continuing to comply with established regulatory standards.

Why Mastercard is entering the stablecoin space

Stablecoins have become one of the fastest growing segments 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 fast transfers, programmable payments, and near-instant settlement across global networks.

By March 2026, the stablecoin market had reached a major milestone, with the total valuation reaching around $314 billion, according to data from DefiLlama. This growth follows a pivotal year in 2025, in which trading volumes reached a record $969.9 billion in a single month. Experts now predict that monthly volumes are on track to surpass the $1 trillion mark by the end of 2026.

For Mastercard, integrating stablecoins into its settlement infrastructure helps ensure the company remains at the heart of the evolving digital payments ecosystem.

Rather than competing with blockchain systems, Mastercard positions itself as a connector between traditional finance and digital asset networks.

Go beyond simple payments

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

Potential uses include:

• Cross-border remittances

• Business-to-business payments

• Cash management tools

• Stablecoin-related card programs

Stablecoins could enable businesses to automate complex financial workflows through programmable transactions.

For example, businesses could automatically release payments when contractual conditions are met, reducing manual interventions and operational costs.

Competition from Visa

Mastercard is not alone among global card networks exploring stablecoin integration. Its main competitor, Visa, has also expanded its use of digital currencies for payment settlement.

Visa has been testing cross-border settlement using stablecoins such as USD Coin (USDC), allowing financial institutions to pre-fund international transfers with tokenized dollars. The company has also explored allowing businesses to send payments directly to stablecoin wallets.

These efforts suggest that stablecoins are becoming a key part of the broader infrastructure competition between major payment networks.

Why regulation will be crucial

The adoption of stablecoins within traditional financial systems is highly dependent on regulation.

Financial institutions need clear regulatory frameworks that address key concerns, including:

Since SoFiUSD is issued by a regulated US bank, it is likely to inspire greater trust among regulators and financial institutions than stablecoins originating in the crypto space.

Payment networks such as Mastercard therefore prioritize regulated stablecoins issued by licensed institutions.

Did you know? Global card payment systems process tens of billions of transactions each year, with card networks processing thousands of payments per second during peak periods like Black Friday and major online retail events.

Challenges to widespread adoption

Despite growing interest, several challenges could limit broader adoption of stablecoin settlement.

These challenges include:

• Integration complexity for banks and payment processors

• Regulatory differences between jurisdictions

• Liquidity management between fiat and digital assets

• Interoperability between blockchains and financial networks

Additionally, consumers are unlikely to notice any major changes, as the technology primarily affects the back-end infrastructure rather than the initial payment experience.

Overview of digital payments

Mastercard’s Stablecoin initiative is part of a broader transformation underway in global finance. Stablecoins were initially used primarily for trading cryptocurrencies. Today, they are increasingly seen as potential tools for payments, remittances and broader financial infrastructure.

If stablecoin settlement proves efficient and reliable, card networks could eventually operate within a hybrid system combining traditional banking rails with blockchain-based digital assets.

Mastercard is not seeking to replace traditional payments. Rather, it is about modernizing the underlying 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 flexible and available 24/7, while ensuring that the average shopper doesn’t notice any difference at checkout.
