DBS and Citi Complete First Weekend USD Payment on Swift Ledger
DBS and Citi have completed the first cross-border U.S. dollar payment between Singapore and the United States over a weekend using tokenized deposits, demonstrating how Swift's emerging blockchain infrastructure can remove the banking-hour constraints that still slow international transfers.
Summary:
- DBS and Citi completed the transaction on Saturday, September 5, between Singapore and New York.
- The payment used tokenized bank deposits, not stablecoins or a public cryptocurrency.
- Swift’s ledger is an EVM-compatible permissioned orchestration layer based on Hyperledger Besu.
- Banks retain control of assets and settlement, while the ledger coordinates payment commitments across institutions.
According to DBS, the live transaction was executed on September 5 between DBS and Citi’s New York office through the Swift Digital Ledger and completed within minutes, compared with an industry norm that can stretch to two business days when weekends and time-zone gaps intervene.
The Weekend Is the Important Part of the Test
Cross-border payments are already capable of moving quickly through existing banking infrastructure. Swift itself says most payments over its network reach beneficiary banks within minutes, although final crediting can still depend on intermediaries, compliance procedures and domestic infrastructure.
The DBS-Citi transaction addresses a different bottleneck: availability.
Traditional correspondent banking is constrained by operating hours, cut-off times and settlement systems in different jurisdictions.
A payment initiated late on Friday can therefore encounter delays even when the messaging technology itself is fast.
DBS and Citi executed their live payment on a Saturday and completed it within minutes. For corporate treasurers, that changes when liquidity can be moved between subsidiaries, suppliers and markets rather than simply reducing the number of seconds required to transmit a payment instruction.
The potential scale is substantial. DBS cited estimates that outbound cross-border payments from Asia could reach $24 trillion by 2033, up from $13.5 trillion in 2025.
Swift’s Ledger Is Not a Stablecoin Network
The architecture is easy to misinterpret because Swift describes the system as blockchain-based and the transaction involved tokenized money.
It is not a public blockchain settlement network comparable with Ethereum, nor does it require banks to send USDC, USDT or another stablecoin.
Instead, Swift’s Digital Ledger provides a shared orchestration layer for participating financial institutions. It records and validates interbank payment commitments while tokenized deposits represent the money involved in the transaction.
The distinction is clearer when the architecture is separated into its components:
- Tokenized deposits represent bank money used by participating institutions.
- Swift operates the shared ledger, coordinating workflows and validating funding commitments.
- Banks retain control of their keys, assets and funding.
- Final settlement remains outside the ledger, using RTGS systems, correspondent banking relationships or another agreed settlement mechanism.
- The ledger itself uses an EVM-compatible architecture based on the open-source Hyperledger Besu framework.
In practical terms, Swift is using blockchain technology to synchronize banks rather than replacing the banking system with an independent crypto settlement asset.
Tokenized Deposits Are Moving Into Live Banking
The DBS transaction also follows another milestone only days earlier.
On September 2, Citi disclosed that it had already processed live USD transactions through Swift’s ledger with First Abu Dhabi Bank and OCBC, making Citi the first U.S. bank to conduct live native ledger transactions in the initiative. DBS and UOB were identified at the time as the next institutions expected to participate.
That makes the September 5 transaction significant for a narrower reason: it demonstrates the model across the Singapore-U.S. corridor during a weekend, when conventional banking-hour constraints are most visible.

Citi is also bringing its own tokenization infrastructure into the broader strategy. Its Citi Token Services platform processes approximately $1 billion in transactions, while the bank’s 24/7 USD Clearing service reaches more than 300 banking clients.
DBS has been building similar infrastructure. The Singapore lender introduced DBS Token Services in 2024, including Treasury Tokens designed for programmable and round-the-clock liquidity transfers. DBS is also the only Asian-headquartered institution in the 12-bank core design group helping shape Swift’s ledger architecture.
Why Swift Is Adding Blockchain Instead of Replacing Its Network
Swift already connects more than 11,500 institutions across over 200 countries and territories, covering more than 40,000 active payment routes.
Building a separate blockchain payment network would risk fragmenting that connectivity. The ledger project instead attempts to add shared-state technology to infrastructure banks already use.
This produces a different model from the stablecoin approach increasingly being explored across crypto and payments.
Stablecoins can move value directly on public or permissioned blockchains, with the token itself functioning as the transferable settlement asset. Swift’s current model leaves assets and settlement under participating banks’ control while using the shared ledger to coordinate the obligations between them.
That design could also make tokenized deposits easier for regulated banks to adopt because existing compliance processes and settlement relationships remain part of the workflow.
The Next Step Goes Beyond Simple Payments
Swift completed the ledger’s design phase earlier this year and is now running its MVP with real-world transactions. Its roadmap includes exploring additional onchain settlement assets and use cases as participating banks test how the infrastructure can scale beyond tokenized deposits.
Potential applications already identified by Swift include programmable corporate payments, payment-versus-payment foreign exchange transactions and cash movements associated with securities settlement.
The current proof-of-concept involving Citi and participating banks runs from July through December 2026, providing several more months to test whether the architecture can function reliably across different institutions and jurisdictions.
The DBS-Citi payment therefore does not show banks abandoning correspondent banking for blockchain. It shows something more incremental: existing banks using a permissioned distributed ledger to make their established payment infrastructure available when conventional settlement schedules would normally be closed.
If that model scales, the competitive question for tokenized payments may become less about whether banks choose blockchain or traditional finance, and more about which parts of the existing banking stack can operate continuously once tokenized deposits and shared ledgers remove the need to wait for Monday morning.
