DBS and Citi Complete Cross-Border USD Payment Using Tokenized Deposits

DBS and Citigroup have completed a cross-border U.S. dollar payment between Singapore and the United States using tokenized deposits through Swift’s blockchain-based Digital Ledger, marking a further step toward round-the-clock settlement infrastructure for international banking.

According to information shared by @WuBlockchain, the transaction was completed on September 5 and took minutes, demonstrating how tokenized deposits can support cross-border payment activity outside conventional banking hours.

Swift Ledger Targets Faster Cross-Border Payments

The transaction forms part of Swift’s broader effort to modernize international payment infrastructure while maintaining connections with existing banking systems. Rather than moving settlement entirely onto a blockchain network, the Digital Ledger is designed to synchronize interbank payment commitments, with the actual settlement remaining off-ledger through established banking infrastructure.

That distinction allows participating financial institutions to explore distributed-ledger technology without requiring a wholesale replacement of the existing settlement system.

The use of tokenized deposits also reflects a growing push among major banks to test digital representations of commercial-bank money for institutional payments. Unlike publicly traded crypto assets, tokenized deposits are designed to remain connected to the banking system and existing financial infrastructure.

DBS and Citi Demonstrate 24/7 Payment Capability

The September 5 transaction is significant because it demonstrates cross-border payment processing that does not depend on traditional banking-hour windows. Completing the transfer within minutes could help address one of the longstanding limitations of international payments, where different operating hours, jurisdictions and settlement processes can introduce delays.

For banks, the approach could provide a pathway toward faster international transactions while preserving established settlement arrangements and controls. It also illustrates how financial institutions are increasingly evaluating blockchain infrastructure as a backend technology rather than solely as a foundation for cryptocurrency markets.

Swift’s ledger initiative will now face a broader test as participating institutions assess how the technology performs across additional payment corridors, currencies and transaction volumes. The key question will be whether the model can move from controlled demonstrations such as the DBS-Citi transaction toward reliable, scalable use across the global banking network.
