15 SEP 2026 — DBS, OCBC and UOB have completed Singapore's first live interbank transactions in Singapore dollars using tokenised deposits, exchanging them through Swift's new blockchain-based ledger. The three banks announced it on 10 September. It is the first time any of them has settled a live interbank payment this way.
The announcement leads on round-the-clock money. The more useful detail is what the blockchain did and did not do, because final settlement still ran through the systems the banks already use.
What actually happened
According to the banks' joint release, payment messages moved between the three through Swift's ledger. Each bank recorded the resulting obligations as tokenised deposits on its own infrastructure. Swift's ledger acted as what the banks call a secure orchestration layer, matching and netting the obligations, and final settlement then took place through existing systems.
A tokenised deposit is an ordinary bank deposit represented as a digital token on the issuing bank's own ledger. It is not a stablecoin and not a central bank digital currency: the money remains a liability of the bank that issued it, covered by the same rules as any other deposit. What the token adds is programmability and the ability to move on a shared network without waiting for a batch cycle.
Programmability is the part with commercial weight. A payment can carry conditions — release when a shipment is confirmed, split automatically across entities, settle only against a matching obligation — rather than relying on people and reconciliation files to enforce them afterwards. None of that was demonstrated in these transactions, which were straightforward payments, but it is the reason banks are building the infrastructure at all.
Swift said in July that its ledger was ready for initial use, with 17 banks across six continents preparing live transactions. Singapore's three are among the first to report one.
Orchestration is not settlement
The architecture is more conservative than the headline suggests. Nobody's deposits moved onto a shared blockchain. Each bank kept its own ledger, Swift's system coordinated between them, and the final transfer of value happened the old way.
That is a sensible design for a first live test, and probably for some time after. It lets banks keep control of their own balance sheets and avoids asking regulators to accept a new settlement asset. It also means the transactions demonstrated coordination and netting across separate ledgers. That is valuable, but it is not the end-to-end blockchain settlement most people picture when they read the phrase.
The coordination problem is also the hard one. Each bank built its own tokenised-deposit system, and tokens that live on three separate ledgers cannot pay each other without something that matches what each owes the others. That is the job Swift's ledger did here, and it is the piece that turns three bank projects into a network.
TNGlobal's reporting was careful on the limits: the banks disclosed no transaction values, no volumes, no participating clients and no date for commercial availability, and nothing about settlement speed, cost or capacity. The announcement establishes that the plumbing works. It does not establish that the service exists for customers.
Why round-the-clock matters, and for whom
DBS's Rachel Chew put the pitch plainly: "In a digital economy, our clients' businesses operate round the clock, and their money should too." She added that the bank's pilots show clients can make US dollar and Singapore dollar payments at any time, including over a weekend.
For a retail customer in Singapore this may sound like a solved problem. PayNow and FAST already move money between individuals instantly, at any hour. The gap tokenised deposits are aimed at is further up the chain: large corporate and interbank flows, treasury movements between entities and currencies, and cross-border payments that still wait for business hours, cut-off times and correspondent banks in other time zones.
A treasurer feels the difference. A payment initiated on a Friday evening in Singapore and due in another currency can sit until Monday. A network that coordinates obligations continuously between banks, and settles when settlement is available, shortens that wait without any bank having to give up control of its ledger.
Singapore's position
The three are Singapore's largest local banks, so their participation covers a large share of the domestic interbank market, not a pilot at its edge. OCBC's Carmen Chan described the transactions as showing the value of industry collaboration, and UOB's So Lay Hua framed its participation as part of a commitment to digital assets and transaction banking.
The release does not mention the Monetary Authority of Singapore, and we have not seen a statement from it. Regional finance ministers have been discussing tokenisation for cross-border payments this year, and a working interbank implementation in one ASEAN market gives those discussions something concrete to point at.
What to watch
A commercial launch date comes first. Until the banks say when a corporate customer can use this, the transactions remain an engineering milestone.
Cross-border use would be the more significant step. Domestic Singapore-dollar payments already work well; the harder and more valuable case is a US dollar or regional-currency payment that currently crosses several banks and time zones.
And any move of settlement itself onto the ledger would change the regulatory conversation entirely. For now, the blockchain coordinates and the old systems still settle.
