SWIFT Runs Live Weekend Transactions on Blockchain Ledger Pilot With 17 Global Banks

BRUSSELS — SWIFT, the cooperative that operates the messaging network underpinning most cross-border bank transfers, is running a pilot of a blockchain-based shared ledger designed to let banks move money around the clock, including on weekends, when most conventional payment rails are closed. The pilot is scheduled to run through December 2026 and involves 17 participating banks, among them Citi, MUFG, DBS, HSBC and Standard Chartered.

The ledger functions as an orchestration layer rather than a settlement system in itself: it coordinates and sequences tokenized-deposit transfers between participating banks in real time, while final settlement continues to occur through banks' existing infrastructure. SWIFT has framed the project as a way to test whether shared ledger technology can extend the availability of cross-border payments beyond current banking-hour windows without replacing the settlement systems banks already rely on.

Several participating banks, including Citi, DBS, HSBC and Standard Chartered, have already executed live transactions on the platform, specifically demonstrating the ability to settle payments over a weekend — a gap in same-day availability that has long been a friction point in cross-border payments, where a transfer initiated on a Friday afternoon in one time zone can otherwise sit until the following Monday in the receiving country.

SWIFT has not disclosed transaction volumes handled during the pilot to date, nor a specific timeline for moving from pilot to broader production use if the trial is deemed successful. The initiative sits alongside a wider push across the banking industry toward tokenized deposits and always-on settlement rails, an area where SWIFT, as the incumbent messaging utility for the vast majority of the world's cross-border bank transfers, has significant incentive to shape the standards rather than cede that ground to competing ledger networks.
