Singapore’s tokenised deposit story is no longer a question of technical feasibility. DBS, OCBC and UOB have settled live interbank SGD transactions on Swift’s ledger; Standard Chartered has a commercial corporate product in market; MAS has a regulatory architecture spanning Project Guardian, BLOOM and pending stablecoin legislation. The remaining obstacles are harder and less photogenic: fragmentation, liquidity management under real-time settlement, and the legal status of on-chain records when disputes arise.
The Fragmentation Trap
MAS Managing Director Chia Der Jiun has identified the core risk with unusual clarity. A single global ledger is unlikely, because financial institutions and jurisdictions will adopt different technologies and infrastructures suited to their markets and regulatory structures. “Without interoperability, liquidity becomes fragmented,” Chia said. “Institutions need to duplicate infrastructure and processes. Network effects become harder to achieve. The result may be many technically capable platforms, but tokenised markets may not be operating efficiently at scale”.
That warning applies directly to tokenised deposits. If each bank issues deposit tokens on its own closed network, corporate treasuries face a familiar problem in a new form: liquidity scattered across incompatible rails, with manual reconciliation reintroduced at the exact point where tokenisation was supposed to eliminate it. Swift’s shared ledger is one response—an orchestration layer that connects separate bank infrastructures rather than forcing consolidation. Project Guardian’s trust-anchor model is another, using verifiable credentials to let regulated institutions interact across open networks without abandoning KYC and AML controls. Neither is yet a universal standard.
Real-Time Settlement Cuts Both Ways
Tokenised deposits enable always-on, atomic settlement, which improves efficiency but also changes the liquidity management burden. Real-time settlement reduces the float that banks and corporates historically relied on to absorb timing mismatches. It can support more efficient capital deployment, but it can also accelerate margin calls and funding outflows during stress periods. For banks, the operational challenge is managing intraday liquidity across tokenised and conventional rails simultaneously, without creating new systemic linkages that supervisors cannot see.
The legal dimension is equally unsettled. A tokenised deposit is still a bank liability, which gives it a clearer compliance and risk profile than a privately issued stablecoin. But the legal finality of an on-chain transfer—how a distributed-ledger record maps to the bank’s books, and what happens if the two diverge—remains an area where market practice is ahead of settled law. Singapore’s existing regulatory perimeter applies, but tokenised deposits sit at the junction of banking law, securities law and payment systems regulation, and the treatment of smart-contract execution in each domain is still being tested.
Coordination Before Scale
MAS’s message to the industry is that scale requires collective movement. “Scale requires customers, counterparties and financial market infrastructure to move together,” Chia said, pointing to the risk that individual banks build capable but isolated deposit-token ecosystems. The BLOOM initiative is designed to test multi-currency, institutional-scale settlement using tokenised bank liabilities and regulated stablecoins, precisely because single-bank pilots cannot answer the interoperability question.
Singapore has moved faster than most jurisdictions in creating live rails and a regulatory framework for tokenised deposits. The next phase is less about invention and more about coordination: common standards for asset servicing, disclosure, risk management and legal finality, so that tokenised deposits can operate as a genuine settlement asset rather than a collection of well-engineered islands.
