Citi, DBS Execute First Weekend USD Payment via Swift’s Digital Ledger

Key Facts

DBS and Citi’s New York office executed the first successful weekend USD payment between Singapore and the United States on September 5, 2026, using tokenized deposits through Swift’s Digital Ledger. DBS said the transaction was completed within minutes, compared with a conventional cross-border payment duration of up to 2 business days.

The test matters because it enables payments outside traditional banking hours on a 24/7 basis. That reduces the effect of time-zone gaps and weekend system closures, without yet establishing that every stage of settlement has become instantaneous.

The use of tokenized deposits does not mean Swift holds customer funds. Its shared ledger acts as an orchestration layer for interbank payment commitments, while banks issue tokenized deposits on their own ledgers and final settlement can occur through existing systems, including real-time gross settlement (RTGS) systems.

On July 9, 2026, Swift said 17 banks across 6 continents were preparing to pilot live ledger transactions. Citi said on September 2, 2026 that the controlled proof-of-concept phase runs from July to December 2026, following live transactions with FAB and OCBC.

For corporate treasurers, the potential benefits include reducing weekend and time-zone gaps, accelerating beneficiary access to funds and increasing flexibility in moving liquidity. One successful transaction demonstrates operability outside conventional hours, but does not by itself establish cost savings or a financial impact on Citi or DBS.

The next test will be how the ledger performs as participant numbers and transaction volumes increase. Swift says functionality and availability will expand after the initial controlled go-live phase, making reliability, liquidity efficiency and integration with existing settlement systems key indicators of scalability.
