US Banks, Mastercard and DBS Are Rewiring Payments for Always-On Digital Finance

Last week showed how the incumbents of payments are responding to stablecoins and always-on digital finance, and the answer is not retreat. America’s biggest banks are joining forces to put deposits on a blockchain. Mastercard is rewiring its settlement layer for stablecoins and 24/7 operation. And in Asia, one of the region’s most digital banks is quietly making bank-to-wallet remittance feel like a domestic transfer. Here is what is happening, and why it matters for merchants, partners and financial institutions.

US Banks Plan a Shared Tokenized Deposit Network for 2027

On 5 June, the Wall Street Journal reported that JPMorgan, Citi, Bank of America, Wells Fargo and other major US banks plan to build a shared Tokenized Deposit Network, with a target launch in the first half of 2027. The system will be operated by The Clearing House, the payments company collectively owned by these banks. It is designed to let regular bank deposits move on a blockchain around the clock while staying entirely inside the regulated banking system, with the same credit risk, regulatory treatment and FDIC coverage that already applies.

The framing is unmistakable. Stablecoins have grown to a roughly 322 billion dollar market, increasingly used for business and institutional payments, and the Clarity Act legislation moving through Congress could allow them to pay interest. That makes them a credible competitor for the deposits that fund bank lending. The infrastructure is also not starting from scratch. JPMorgan already runs JPM Coin on its private Kinexys platform for institutional clients and launched a tokenised deposit on Coinbase’s Base network earlier this year. Citi operates Token Services for real-time transfers between New York, London and Hong Kong. The new shared network would extend that pattern across the US banking system, with The Clearing House as the operator and the Federal Reserve as the audience that matters most.

Why it matters: This is the clearest signal yet that tokenised money is moving from the margins into the core of US payments. If the largest banks can offer 24/7 programmable transfers without customers having to leave the banking system for a stablecoin, the case for stablecoin yield products weakens and the gravitational pull of bank deposits holds. The flip side is that the rails of US dollar payments will increasingly look like blockchains, regardless of which side of the debate wins.

The Debia angle: Our long-held view is that the future of settlement is interoperability between traditional rails and compliant digital assets, with regulation built into the foundation. A bank-operated tokenised deposit network is exactly that thesis playing out in the US, with the regulator inside the perimeter rather than outside it. The lesson for everyone in payments is that customers do not care whether their money moves on a card network, a real-time rail or a tokenised deposit, they care that it arrives fast, predictably and safely. Debia is built around that principle, orchestrating across rails so the experience stays simple while the plumbing evolves.

Mastercard Opens 24/7 Stablecoin Settlement Across Eight Blockchains

On 3 June, Mastercard announced a significant expansion of its settlement capabilities. Card issuers and acquirers will now have the option to settle transactions during intraday windows, on weekends and on public holidays, both in fiat and on chain using regulated stablecoins. The supported stablecoins include Circle’s USDC, PayPal’s PYUSD, Ripple’s RLUSD, USDG, USDP and SoFiUSD, with settlement enabled across eight blockchain networks: Ethereum, Solana, Polygon, Base, Arbitrum, Canton, Tempo and XRPL. The first wave of partners, ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank and Nuvei, will start in the United States and Latin America, with broader expansion through 2026.

The change matters because traditional card settlement is still bounded by banking hours. Cross-border fintechs and merchants typically pre-fund accounts or wait 48 to 72 hours for fiat to clear after a weekend or holiday, which ties up working capital and increases counterparty risk in long chains of correspondent banks. Mastercard’s framing is that the next phase of stablecoin adoption is about real-world utility, especially in settlement, where timing and liquidity matter most. The new capability runs alongside existing fiat settlement rather than replacing it, so partners can mix traditional and on-chain settlement through the same global infrastructure they use today.

Why it matters: Settlement has been one of the slowest layers in payments to modernise, and Mastercard turning on 24/7 and on-chain settlement at network scale puts real pressure on the rest of the ecosystem. For acquirers, fintechs and merchants, faster settlement releases working capital that has been sitting idle through nights, weekends and holidays. For stablecoin issuers, it accelerates the move from trading instrument to embedded settlement asset, and it materially increases the volume that flows through regulated stablecoins.

The Debia angle: We have consistently said that the next decade of payments belongs to providers who can route across cards, account-to-account, real-time rails and compliant digital assets, and present a single, predictable experience to the merchant. Mastercard’s move is a sharp example of why. The infrastructure underneath is becoming more diverse and more programmable, and the value sits with the orchestration layer on top. That is exactly where Debia builds, so that as new settlement options arrive, the merchant experience stays clean and the cost benefits flow through.

DBS Opens Weixin Pay Funding to All Singapore Residents

In Singapore, DBS announced on 5 June that DBS Remit users can now transfer funds directly to Weixin Pay, the digital RMB wallet inside the Weixin and WeChat apps, regardless of nationality. Until now, the feature was limited to account holders with Chinese, Hong Kong or Macau identity documents. Singaporeans, permanent residents and foreigners residing in Singapore can now use the service by verifying their passports in the DBS digibank app. The announcement also serves as a status update on the original February launch with TenPay Global, Tencent’s cross-border payments arm, with customer numbers up roughly fourfold, transaction volumes up eightfold and average transfer sizes climbing past 800 Singapore dollars.

Behind the headline is a broader strategic story. DBS has been deepening its cross-border payments network across Asia, with growing scan-to-pay and remittance linkages into India, Indonesia, Malaysia and Thailand, and a layered partnership with Tencent that will eventually let DBS PayLah! users scan Weixin Pay QR codes at merchants across mainland China. The pitch to the customer is simple. Funding a Chinese wallet from a Singapore bank account, with no fees and instant credit, gives travellers, students and families a cleaner alternative to credit card top-ups, FX markups and platform charges.

Why it matters: Singapore’s digital wallet and remittance ecosystem is one of the most developed in the world, but the friction in linking a domestic bank account directly to a Chinese consumer wallet has been persistent. Removing that friction at scale, through a major bank, materially reshapes how Singapore residents pay across the most important consumer corridor in Asia. Expect more bank-to-wallet integrations across ASEAN as competition for cross-border transaction share intensifies.

The Debia angle: Cross-border payments that feel as smooth as domestic ones are the standard we work toward at Debia. The lesson here is that the winners are not necessarily the providers with the cheapest rate, they are the ones who plug their infrastructure into the wallets and platforms customers already use. DBS is connecting one of the region’s most trusted banks to one of the world’s most used consumer wallets, and the experience for the user reduces to a verified passport and a tap. That same instinct, hide the plumbing and meet customers where they already are, sits at the centre of how Debia builds payment infrastructure for merchants and partners across the region.

At Debia, we track these changes because the future of payments will be shaped by speed, trust, interoperability, and smarter financial infrastructure. We do not just process payments. We understand the infrastructure, regulation, technology, and market shifts behind the future of digital commerce, and we build for where the ecosystem is heading next.
