Singapore-based DBS and Citigroup have completed a cross-border US dollar payment between Singapore and the United States using tokenised deposits, demonstrating how blockchain-based banking infrastructure could help remove the traditional time and day restrictions surrounding international payments.
The transaction was completed on September 5, 2026, over a weekend, using tokenised deposits through the Swift Digital Ledger and Citi’s New York operations. DBS said the payment was completed within minutes, compared with conventional cross-border transactions that can take as long as two business days because of time-zone differences, weekends and banking cut-off periods.
The development represents another step in the financial industry’s push toward always-on payment infrastructure, particularly for institutional and corporate transactions.
Moving Beyond Traditional Banking Hours
Cross-border payments have traditionally depended on a combination of messaging networks, correspondent banks and settlement systems that operate around business hours. While digital banking has made it possible to initiate payments at almost any time, the underlying movement and settlement of funds can still be constrained by banking schedules.
The DBS-Citi transaction demonstrates a different approach.
By using tokenised deposits, the participating banks were able to represent bank-held money in digital form and transfer it through blockchain-based infrastructure. The September 5 payment was executed during a weekend, highlighting the potential for transactions to continue even when traditional banking systems are operating outside normal settlement windows.
For companies making international payments, the difference could eventually translate into faster access to funds and more predictable liquidity management.
Tokenised Deposits Enter a More Practical Phase
Tokenised deposits are becoming an increasingly important area of institutional fintech development. Unlike conventional cryptocurrencies, tokenised deposits represent money held within the banking system and are designed to combine the properties of commercial bank deposits with blockchain-based transfer capabilities.
The DBS-Citi transaction is particularly notable because it involves established financial institutions testing the technology in an actual cross-border payment environment rather than limiting it to a laboratory or proof-of-concept setting.
Citi has also been expanding its own blockchain-based payment infrastructure. The bank recently announced live transactions on Swift’s blockchain-based ledger with First Abu Dhabi Bank and Singapore’s OCBC, describing the initiative as part of efforts to develop always-on, cross-border and interoperable payment capabilities.
Why 24/7 Settlement Matters
The ability to move US dollars across borders during weekends could be particularly valuable for multinational companies and financial institutions managing large international cash positions.
A business that currently has to wait for the next banking day to complete a transaction could potentially settle funds within minutes. That could improve treasury management, reduce idle liquidity and provide companies with greater flexibility when dealing with suppliers and counterparties in different time zones.
However, the technology does not eliminate every challenge surrounding cross-border payments. Regulatory requirements, foreign-exchange processing, compliance checks and connections to local payment systems will continue to influence how quickly funds can ultimately reach recipients.
Still, the DBS-Citi transaction provides evidence that banks are moving closer to an infrastructure where cross-border payments can operate continuously rather than being tied to traditional banking calendars.
The broader significance is that tokenisation is increasingly being tested as a practical component of financial infrastructure. As more banks connect to blockchain-based settlement networks, the focus is shifting from whether tokenised money can work to how it can be integrated into the global payments system at scale.
