Mastercard brings stablecoins into card settlement infrastructure

Mastercard is expanding its settlement capabilities to support regulated stablecoins, intraday settlement, and card settlement over weekends and public holidays, in a move that underlines the growing convergence between traditional payments infrastructure and blockchain-based value transfer.

Mastercard to support regulated stablecoins

The card network says the enhanced settlement model will give issuers, acquirers and payment partners greater flexibility in how and when they settle transactions across Mastercard’s global network.

While card payments have long offered near-instant consumer experiences at the point of sale, the underlying settlement process has often remained tied to conventional banking hours and fiat-based clearing cycles.

By introducing additional settlement optionality, including on-chain settlement using regulated stablecoins, Mastercard is positioning itself for an “always-on” payments economy in which treasury, liquidity and cross-border flows increasingly need to operate outside traditional market windows.

The initiative will support stablecoins including Circle’s USDC, Paxos-issued PYUSD, USDG and USDP, Ripple’s RLUSD and SoFiUSD. These assets will be enabled across a range of blockchain networks, including Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo and XRPL.

Stablecoins Move From Speculation to Infrastructure

The announcement is significant because it frames stablecoins not as a consumer-facing crypto product, but as a practical settlement instrument for regulated payments participants. For issuers and acquirers, the potential benefits are less about novelty and more about liquidity management, transparency, speed and operational flexibility.

Mastercard said the enhanced capability is particularly relevant for cross-border payments, treasury operations and payouts, where timing and certainty of settlement can have a material impact on working capital and risk management.

Raj Dhamodharan, Mastercard’s executive vice president for Blockchain and Digital Assets, said the next phase of stablecoin adoption is about “real-world utility”, especially in settlement, where liquidity and timing matter most. His comments reflect a wider shift in the digital asset sector, where institutional interest is increasingly centred on regulated stablecoins as programmable settlement assets rather than speculative tokens.

Among the first organisations expected to support stablecoin settlement optionality are ARQ, formerly DolarApp, CBW Bank, Cross River, Lead Bank and Nuvei, with initial activity focused on the United States and Latin America. Further expansion is planned through 2026, subject to regulatory conditions.

A Pragmatic Bridge Between Fiat and On-Chain Payments

Mastercard is careful to present the development as an extension of existing infrastructure rather than a replacement for established settlement models. Partners will be able to access traditional and digital asset-based settlement through the same global network, while retaining Mastercard’s security standards, fraud controls and dispute processes.

That positioning is important. For large financial institutions, the appeal of stablecoin settlement will depend not only on speed, but also on regulatory confidence, operational resilience and interoperability with existing systems.

The move also demonstrates how major payment networks are seeking to absorb blockchain capabilities into mainstream financial infrastructure, rather than allowing parallel rails to develop entirely outside their ecosystems.

For stablecoins, Mastercard’s support represents another step towards institutional legitimacy. For card settlement, it signals the beginning of a more flexible, programmable and potentially 24/7 operating model.
