On 10 September 2026, Singapore’s banking landscape crossed a threshold that had been approaching for years. DBS, OCBC and UOB completed live domestic Singapore dollar transactions using tokenised deposits on Swift’s blockchain-based ledger—the first time the three local banks had executed interbank SGD transfers in tokenised form. The transactions were not simulations. They settled real value, between real institutions, on infrastructure designed to operate beyond traditional banking hours.
Why the Interbank Milestone Matters
Tokenised deposits are not a new asset class. They are ordinary bank deposits issued in digital token form, carrying the same legal claim against the issuing bank and the same deposit insurance treatment as a conventional account balance. What changes is the rail: value moves across a shared ledger rather than through sequential messaging and batch processing. For corporate clients, the implication is direct. DBS’s Group Chief Operating Officer and Co-Head of Digital Assets, Rachel Chew, framed the shift in client terms: businesses operate around the clock, and “their money should too,” with tokenised deposits enabling USD and SGD payments “any time, any day, including over a weekend”.
The interbank dimension is what makes September’s milestone more than a single-bank product launch. By connecting separate tokenised-deposit ecosystems across DBS, OCBC and UOB, Swift’s ledger addresses the fragmentation problem that has slowed institutional adoption. Swift announced in July 2026 that its ledger was ready for initial use, with 17 banks across six continents preparing live transactions using tokenised deposits. Singapore’s three banks moved first on domestic SGD, demonstrating that the architecture can handle a single currency area’s internal payment needs, not only cross-border corridors.
The Architecture Behind the Transactions
The transactions sit within a broader MAS strategy that treats tokenised bank deposits as one settlement asset among several. MAS has consistently argued that wholesale central bank digital currency, tokenised deposits and well-regulated stablecoins should coexist as complementary settlement instruments rather than compete for a single monopoly role. Project Guardian, the MAS-convened industry programme, provided the collaborative framework; Swift’s ledger supplied the interoperability layer that lets obligations on separate bank infrastructures be matched and netted before final settlement through existing systems.
OCBC’s Deputy Head of Global Transaction Banking, Carmen Chan, described the live SGD interbank transactions as evidence of how shared-ledger technology can “unlock new payment capabilities for businesses while maintaining the trust and resilience of today’s financial system”. UOB’s Head of Group Transaction Banking, So Lay Hua, noted that the bank had expanded from Hong Kong dollar to Singapore dollar and US dollar transactions beyond traditional banking hours, positioning tokenised infrastructure as a connectivity play across markets and time zones.
What Comes Next for Singapore’s Deposit Tokens
The September transactions do not mean that tokenised deposits will immediately replace conventional balances in corporate treasuries. They do mean that the question has shifted from technical feasibility to commercial design: which balances belong on a tokenised rail, which remain on conventional rails, and how the two coexist within a single liquidity framework. The Monetary Authority of Singapore has signalled that scaling requires customers, counterparties and financial market infrastructure to move together, rather than banks building isolated deposit-token ecosystems. Singapore’s first live interbank SGD tokenised deposit transactions give that coordination effort a working reference point—and a deadline pressure that pilots alone never created.
