DBS Bank and Citigroup have completed the first weekend cross-border USD settlement between Singapore and the United States using tokenized deposits and Swift's blockchain-based ledger, advancing the prospect of round-the-clock institutional payment rails that operate outside conventional banking hours.

According to The Block, the two banking giants executed the payment on a weekend, marking the first time a cross-border USD transfer between Singapore and the U.S. has been settled during that window via tokenized deposits. The transaction leveraged Swift's distributed ledger infrastructure to move value across borders at a time when traditional correspondent banking networks are typically offline and unable to process settlement.

CoinDesk reported that the transfer represents the second confirmed live use of Swift's digital ledger. The publication noted that the milestone comes as the global messaging network works to demonstrate that it can rival digital payment rails that operate continuously, addressing a longstanding gap between legacy banking hours and the around-the-clock expectations increasingly demanded by institutional finance.

Cointelegraph stated that Citi and DBS specifically used Swift's blockchain-based ledger to avoid the restrictions of traditional banking hours. By issuing and transferring tokenized deposits on the ledger, the banks were able to settle the USD transaction without waiting for the opening of the next business day in either Singapore or the United States.

Tokenized deposits, which are bank-issued digital representations of fiat currency maintained on blockchain ledgers, have emerged as a key mechanism for enabling programmable, instantaneous transfers while preserving the regulatory protections and deposit insurance frameworks associated with conventional bank money. The successful weekend settlement suggests that major global banks are increasingly willing to integrate distributed ledger technology into core treasury and cross-border operations to achieve continuous settlement availability.

The development also underscores Swift's strategic evolution in the face of blockchain-native competitors and real-time payment systems that have increasingly drawn volume away from conventional wire transfers. Rather than allowing standalone digital asset networks to capture the 24/7 institutional payments market entirely, the cooperative is actively deploying its own ledger infrastructure to bridge the gap between traditional correspondent banking and tokenized settlement systems.

While the specific value of the weekend transfer was not disclosed by either institution, the transaction serves as a functional proof-of-concept that institutional-grade cross-border settlements can occur securely outside the standard Monday-to-Friday window. As competition intensifies between legacy financial infrastructure and emerging digital settlement networks, the DBS-Citi demonstration indicates that tokenized deposits operating on established banking networks may offer a regulated, compliant pathway to uninterrupted global liquidity for corporate and institutional clients.
