Swift’s Blockchain Ledger: 50+ Banks Building 24/7 Cross-Border Payments

From Design to Live Transactions

Swift, the backbone of global interbank messaging connecting 11,000+ institutions across 200+ countries, announced in March 2026 that it has completed the design phase of a blockchain-based shared ledger and is actively building its first Minimum Viable Product. The ledger will enable banks to make cross-border payments around the clock using tokenized commercial bank deposits, eliminating the weekend and holiday delays that have plagued international money transfers for decades.

The system is built on an Ethereum Virtual Machine-compatible architecture based on Hyperledger Besu, an open-source enterprise blockchain framework, using Linea — an Ethereum layer-2 network developed by ConsenSys. The choice of open-source foundations signals that the ledger will be interoperable and auditable rather than proprietary. The MVP builds on existing bank payment applications and Swift standards, meaning banks do not need to rebuild core systems to participate.

More than 50 financial institutions have signed up to support the framework, expanding from the 30 originally named when Swift unveiled the project at its Sibos conference in Frankfurt in September 2025. Participants include JPMorgan Chase, HSBC, BNP Paribas, Deutsche Bank, Bank of America, and Lloyds Bank. More than 25 banks are expected to go live by June 2026.

How Tokenized Deposits Solve the Correspondent Problem

Cross-border payments today involve a chain of correspondent banks, each operating during their own business hours and time zones. A transfer from an Algerian bank to a supplier in China might pass through intermediary banks in London and Singapore, taking three to five days and accumulating fees at each step. Weekend and holiday closures compound the problem.

Tokenized deposits are digital representations of commercial bank deposits on a distributed ledger. Unlike stablecoins or cryptocurrencies, they are claims on regulated bank deposits carrying the same protections — deposit insurance, central bank backing, regulatory oversight — as traditional bank balances.

When Bank A in France wants to send payment to Bank B in Japan, the ledger records a commitment: Bank A’s tokenized deposits are debited and Bank B’s are credited, with the transaction validated by the shared ledger rather than requiring sequential confirmations from intermediary banks. Settlement can occur in minutes rather than days. The system supports multiple settlement options, meaning it can work alongside existing payment rails rather than replacing them entirely.

Proven in Trials

Swift has already validated the approach through multiple trials. A November 2025 trial with Citi used USDC stablecoin. A December proof-of-concept with HSBC and Ant International tested tokenized deposit transfers. In January 2026, BNP Paribas Securities Services, Intesa Sanpaolo, and Societe Generale FORGE successfully settled tokenized bonds against fiat and digital payments.

The breadth of participation is critical. Previous blockchain payment initiatives struggled because they required bilateral agreements between specific banks. Swift’s approach leverages its existing network — any bank connected to Swift can potentially participate without negotiating individual agreements with every counterpart. This network effect is difficult for competitors to replicate.

Competitive Positioning

Swift’s move is a strategic response to growing competition in cross-border payments. Fintech companies like Wise have built consumer-friendly alternatives that bypass traditional correspondent banking. Stablecoin payment providers target enterprise cross-border flows. Ripple has promoted XRP as a bridge currency for interbank settlement.

By building its own blockchain-based solution, Swift defends its position as the central coordinating layer for global banking while incorporating the technological innovations that competitors used to challenge its dominance. The use of a permissioned enterprise blockchain rather than a public chain keeps the system within the regulatory comfort zone of traditional banks.

The transition from design to live operations in under a year is ambitious by banking standards. If successful, faster settlement reduces working capital tied up in transit, lower fees benefit both sending and receiving parties, and 24/7 availability removes a friction point that has persisted since the telegraph era.
