DBS and Citi have successfully completed the first U.S. dollar payment between Singapore and the United States executed over a weekend using tokenized deposits on Swift’s Digital Ledger, demonstrating how blockchain infrastructure could enable banks to move money internationally around the clock.
The live transaction took place on September 5 between DBS in Singapore and Citi’s New York office. The payment settled within minutes, compared with an industry norm that can take as long as two business days for conventional cross-border payments.
The milestone represents another real-world test of Swift’s effort to modernize the infrastructure connecting the global banking system while preserving interoperability between traditional financial institutions and emerging tokenized networks.
Tokenized Deposits Enable 24/7 Payments
Tokenized deposits are digital representations of commercial bank deposits recorded on blockchain-based infrastructure. Unlike many stablecoins, they remain directly connected to deposits issued by regulated banks.
By moving these deposits across Swift’s Digital Ledger, DBS and Citi demonstrated that cross-border dollar payments can take place outside conventional banking hours.
That distinction was particularly important in this transaction because it occurred on a Saturday. Instead of waiting for banks and settlement infrastructure to reopen after the weekend, the transaction was processed in minutes.
For corporations operating across different jurisdictions and time zones, the model could improve liquidity management by allowing funds to move whenever they are required rather than according to banking calendars.
DBS said the capability could be particularly useful for industries such as e-commerce and digital services, where commercial activity already operates continuously. Corporate treasury departments could also move liquidity between entities and markets more rapidly when responding to changing conditions.
Swift Pushes Blockchain Into Global Banking
Swift’s Digital Ledger represents a significant expansion of the financial messaging network into blockchain-based settlement.
The platform was launched earlier in 2026 with participation from major international financial institutions as Swift works to provide 24/7 tokenized payments without requiring banks to abandon their existing infrastructure. Citi is among the banks involved, while DBS is the only Asian-headquartered institution in the 12-bank core design group shaping the ledger’s architecture.
The DBS-Citi payment was the second confirmed live transaction on the ledger. HSBC and Standard Chartered previously completed Swift’s first live transaction in the pilot in August.
That progression suggests the technology is moving beyond proofs of concept toward real transactions between major financial institutions.
Banks Race Toward an Always-On Financial System
The development comes as banks face growing competition from stablecoins and blockchain payment networks capable of settling transactions continuously.
Rather than replacing commercial bank money with independent digital currencies, tokenized deposits offer banks a way to bring traditional deposits onto programmable digital infrastructure while retaining their existing regulatory and institutional frameworks.
DBS has already been developing this model through DBS Token Services, which launched in 2024 and provides blockchain-based banking capabilities including programmable and instantaneous transfers.
The potential market is substantial. DBS cited industry projections estimating that outbound cross-border payments from Asia could reach $24 trillion by 2033, compared with $13.5 trillion in 2025.
The successful weekend transaction between DBS and Citi therefore represents more than a technical demonstration. It shows how some of the world’s largest banks are beginning to connect conventional deposits with blockchain infrastructure capable of operating continuously.
If the model scales, the traditional distinction between banking hours and digital payment hours could increasingly disappear.
