DBS, OCBC and UOB completed live domestic Singapore-dollar interbank transactions using tokenised deposits on Swift’s blockchain-based ledger, moving a planned industry trial into an executed local payment process.
The banks exchanged payment messages through Swift. The resulting obligations were recorded on each bank’s own tokenised-deposit infrastructure, while Swift’s ledger matched and netted those obligations before final settlement took place through existing banking systems. DBS joint bank announcement
What the ledger did and did not do
That sequence matters because the ledger did not replace bank deposits or move final settlement wholesale onto a blockchain. Tokenised deposits remain liabilities of regulated banks in digital form. Swift provided a shared coordination layer between separate bank systems, while established settlement arrangements completed the transfer. Swift ledger initial-use announcement
The 10 September announcement describes the transactions as the first time Singapore’s three local banks executed live interbank transactions using tokenised deposits. It follows Swift’s July declaration that its ledger was ready for initial use, when 17 banks across six continents were preparing live transactions.
The domestic SGD work is part of a wider sequence rather than an isolated demonstration. UOB and HSBC completed live Hong Kong-dollar transactions on the ledger in August. DBS and Citi then completed a separate live weekend US-dollar payment between Singapore and New York on 5 September. Those transactions involved different banks, currencies and payment routes, so their operating results should not be transferred to the new domestic SGD event.

A live milestone, not a broad product launch
The joint announcement establishes that real interbank payment obligations were processed. It does not disclose the transaction values, participating customers, processing time, settlement window, fees, production volumes or a date for broad commercial availability. It also does not show that companies can yet replace their existing treasury processes with the service.
For corporate finance teams, the potential value is clearer than the current product scope. Shared-ledger coordination could eventually support payments outside traditional processing windows and reduce friction between separate tokenised-deposit systems. The banks point to possible future uses in treasury, trade and digital commerce, but these are prospective applications rather than measured outcomes from the disclosed transactions.
Questions before wider use
The practical test now moves from technical execution to repeatable operations. Banks and corporate users will need evidence on cut-off times, liquidity treatment, reconciliation, exception handling, compliance controls, pricing and legal finality. They will also need to know which payment types and customer segments can use the service and how failures are resolved when the ledger and existing settlement systems interact.
For Southeast Asia, the milestone is significant because DBS, OCBC and UOB operate across the region and serve companies managing multiple currencies and banking relationships. The announcement does not establish an ASEAN rollout, however. Expansion beyond Singapore will depend on local regulation, participating banks, settlement infrastructure and the availability of tokenised deposits in each market.
The established result is narrow but meaningful: three regulated Singapore banks have completed live domestic SGD interbank transactions through a shared orchestration ledger. The useful next disclosures are whether the service becomes broadly available and whether it delivers measurable treasury benefits.
