DBS and Citi finalize weekend US‑dollar transfer through SWIFT’s Digital Ledger using tokenized deposits

In a notable development for the global payments ecosystem, two of Asia’s leading financial institutions—DBS Group and Citi—successfully completed a cross‑border United States dollar transaction over the weekend using SWIFT’s newly introduced Digital Ledger technology. This operation, which relied on tokenized deposits as the underlying settlement mechanism, represents the second confirmed live use case of SWIFT’s blockchain‑style ledger since its launch.

The achievement is significant not only because it demonstrates the practical viability of the Digital Ledger but also because it underscores the broader industry effort to create a payment rail that can operate continuously, without the downtime that traditionally hampers legacy systems. **Background and context** SWIFT, the long‑standing cooperative that connects more than 11,000 financial institutions worldwide, has been actively exploring distributed‑ledger technologies (DLT) for several years. The goal is to augment its existing messaging infrastructure with a shared, immutable ledger that can provide real‑time visibility, reduce reconciliation costs, and enhance the overall speed of settlement.

The Digital Ledger, first announced in 2022, is built on a permissioned blockchain framework that allows participating banks to record tokenized assets—essentially digital representations of fiat currency—on a common ledger. By tokenizing deposits, banks can move value instantly across borders while still retaining the regulatory safeguards and audit trails required by central banks and supervisors. The first live deployment of the Digital Ledger involved a transaction between two European banks, which was widely reported in early 2024.

That pilot proved that the technology could handle a modest transfer with the expected level of security and compliance. The weekend transaction between DBS and Citi now serves as the second live confirmation, and it is particularly noteworthy because it involved a larger amount of US dollars and was executed outside of normal business hours, highlighting the ledger’s ability to function 24/7. **How the transaction worked** The process began when DBS, acting as the sender bank, initiated a payment instruction to move a specified sum of US dollars to a beneficiary account held by Citi.

Rather than routing the payment through the traditional correspondent banking network—where multiple intermediary banks might be involved, each adding fees and processing time—the two institutions leveraged the SWIFT Digital Ledger. First, DBS converted the fiat amount into a tokenized deposit, a digital token that mirrors the value of the underlying US dollars and is recorded on the shared ledger. This token is fully backed by the corresponding cash reserve held by DBS, ensuring that the token’s value is always redeemable.

Once the token was created, it was transferred on the ledger to Citi’s custody account. Because the ledger is a single source of truth, both banks could instantly verify the token’s authenticity, ownership, and the fact that it had not been double‑spent.

Citi then redeemed the token for actual US dollars from its own reserve, completing the settlement. Throughout the entire flow, SWIFT’s messaging layer provided the necessary compliance checks, anti‑money‑laundering (AML) screening, and sanctions screening, ensuring that the transaction met all regulatory requirements. **Why this matters** The successful weekend execution demonstrates several key advantages of the Digital Ledger approach: 1.

**Speed and availability** – Traditional cross‑border payments often rely on a series of batch processes that run only during business hours in the participating jurisdictions. By using a ledger that is operational 24/7, banks can settle transactions instantly, even on weekends and holidays. 2.

**Transparency and reconciliation** – Because every token movement is recorded on a shared ledger, both sender and receiver have immediate, immutable proof of the transaction. This reduces the need for manual reconciliation and lowers operational risk.

3. **Cost efficiency** – Eliminating multiple correspondent banks reduces intermediary fees and foreign exchange spreads, leading to lower overall costs for corporate clients and consumers alike.

4. **Regulatory compliance** – The permissioned nature of the ledger ensures that only vetted institutions can participate, while built‑in audit trails satisfy supervisory expectations for traceability and anti‑fraud controls. **Implications for the broader payments landscape** The Digital Ledger’s growing track record comes at a time when alternative digital payment rails—such as RippleNet, Stellar, and various central bank digital currency (CBDC) initiatives—are vying for market share.

Many of these platforms promise near‑instant settlement, but they often face challenges related to regulatory acceptance, network effects, and integration with existing banking infrastructure. SWIFT’s approach leverages its already‑established global network and compliance framework, offering a hybrid model that blends the reliability of legacy messaging with the innovation of blockchain.

Moreover, the use of tokenized deposits aligns with the broader industry trend toward digital representation of fiat currencies. As central banks explore CBDCs, the ability to issue, transfer, and redeem tokenized cash on a secure ledger could become a foundational capability for future payment systems.

Banks that have already experimented with tokenization—such as DBS, which has been a pioneer in digital banking in Southeast Asia—are well‑positioned to adopt and scale these solutions. **Future outlook** Both DBS and Citi have indicated that they view the weekend transaction as a pilot for broader adoption. They plan to test higher volumes, larger transaction sizes, and more complex use cases such as multi‑currency settlements and supply‑chain finance.

In parallel, SWIFT is expanding the Digital Ledger’s participant base, inviting additional banks, payment service providers, and possibly non‑bank entities to join the network. If the momentum continues, the Digital Ledger could become a cornerstone of a new, always‑on global payments infrastructure that rivals private‑sector blockchain networks and traditional correspondent banking. For corporates, the promise of faster, cheaper, and more transparent cross‑border payments could unlock new trade opportunities and improve cash‑flow management.

For consumers, it could mean quicker remittances and reduced fees when sending money abroad. In summary, the weekend US‑dollar transfer between DBS and Citi via SWIFT’s Digital Ledger not only validates the technology’s operational readiness but also signals a shift toward a more resilient, real‑time global payments ecosystem. As more institutions experiment with tokenized deposits and shared ledgers, the financial industry moves closer to a future where money can move as swiftly and securely as data, 24 hours a day, seven days a week.
