Singapore's Digital Currency Initiative: Building the Infrastructure for Programmable Money
Key Takeaways
- MAS completed its first live wholesale CBDC settlement trial in 2025, with DBS, OCBC, and UOB settling interbank overnight lending.
- Singapore has no plans for a retail CBDC - MAS sees “no urgent need” but is building infrastructure to be ready if that changes.
- Tokenised MAS Bills settled via wholesale CBDC are planned for a 2026 pilot with Primary Dealers.
- Purpose Bound Money (PBM) enables programmable spending conditions on digital SGD - tested by Amazon, HSBC, Grab, and Ant International.
- BLOOM, launched October 2025, extends Singapore’s settlement capabilities for cross-border tokenised asset exchange.
What Is Project Orchid?
Project Orchid is the Monetary Authority of Singapore’s (MAS) multi-year initiative to design and develop the infrastructure for a digital Singapore dollar. Rather than building a single digital currency product, Project Orchid examines the technical requirements across four pillars - a settlement ledger, Purpose Bound Money (PBM), a tokenisation bridge, and a name service - enabling MAS to activate capabilities individually or in combination as policy and commercial needs evolve. The project has moved from research into live trials, with wholesale CBDC settlement completed in 2025 and tokenised MAS Bills planned for a 2026 pilot.
Singapore’s Monetary Authority (MAS) has taken a deliberate, infrastructure-first approach to digital currency. Rather than rushing to issue a retail digital dollar, MAS has built a modular framework - Project Orchid - that develops the underlying technology for programmable money, wholesale settlement, and tokenised asset infrastructure. The approach is pragmatic: prepare the capabilities now, deploy them when commercial and policy needs justify it.
Project Orchid: Four Pillars
Project Orchid is a multi-year, multi-phase initiative examining the design and technical requirements for a digital Singapore dollar. The project is built on four foundational elements:
Project Orchid Components
| Component | Purpose | Status (March 2026) | Key Partners | Source |
|---|---|---|---|---|
| Settlement Ledger (SGD Testnet) | Shared ledger for settling tokenised financial assets using wholesale CBDC | Live - first successful trial completed 2025 | DBS, OCBC, UOB | MAS Media Release, Nov 2025 |
| Purpose Bound Money (PBM) | Programmable money with specified conditions of use | Trials ongoing - multiple use cases tested | Amazon, HSBC, Grab, Ant International, Fazz | MAS Project Orchid |
| Tokenisation Bridge | Infrastructure connecting tokenised assets to existing payment rails | In development | JPMorgan, Standard Chartered | MAS SFF 2025 |
| Name Service | Identity layer for digital currency transactions | Research phase | TBC | MAS Project Orchid |

Each component can operate independently or in combination, giving MAS flexibility to activate capabilities as market demand and policy requirements evolve.
The Wholesale CBDC Milestone
The most significant development came in 2025 when MAS announced the successful live trial of interbank overnight lending settled using wholesale CBDC. This was the first live issuance of Singapore dollar wholesale CBDC, with transactions recorded in the participating banks’ official books and regulatory filings - not a sandbox simulation.
DBS, OCBC, and UOB participated as the three payment infrastructure partners, demonstrating that wholesale CBDC can function as a settlement asset for interbank transactions on a shared ledger.
Building on this success, MAS has announced plans to issue tokenised MAS Bills to Primary Dealers in a 2026 pilot, with settlement conducted using CBDC. This would bring government securities onto blockchain-based infrastructure for the first time in Singapore, creating a reference implementation for tokenised fixed income.
Purpose Bound Money: Programmable Spending
Purpose Bound Money (PBM) is perhaps the most commercially relevant element of Project Orchid. PBM allows the creator of a digital payment to specify conditions on how the money can be used - effectively programmable spending rules embedded in the currency itself.
The concept has moved well beyond theory. MAS has overseen trials across multiple use cases:
- OCBC and UOB explored the interchangeability of digital tokens between banks, testing whether PBM issued by one institution could be accepted and redeemed by another.
- Grab, Ant International, and Fazz tested PBM for consumer and merchant payments, exploring how programmable conditions could automate payment flows in e-commerce and transport.
- Amazon and HSBC trialled PBM applications for merchant financing and operational efficiency, demonstrating enterprise-grade use cases for programmable money.
For fintech platforms and neobanks, PBM opens new possibilities in escrow automation, conditional payments, loyalty programmes, and trade finance - areas where payment conditions currently require manual enforcement or intermediary oversight.
No Retail CBDC - By Design
A common misconception about Project Orchid is that Singapore is building a retail CBDC. MAS has been explicit: there is currently “no urgent need” for a retail central bank digital currency in Singapore. The country’s existing payment infrastructure - PayNow, FAST, and widespread card acceptance - already provides efficient digital payments for consumers.
Instead, MAS is building the underlying infrastructure so that a retail CBDC could be deployed if circumstances change - for example, if private digital currencies gained sufficient adoption to threaten monetary sovereignty, or if specific use cases (such as offline payments or financial inclusion for underbanked populations) created a compelling policy case.
This “infrastructure first, deployment later” approach distinguishes Singapore from countries like China (which has actively deployed the digital yuan for retail use) and central banks that have chosen not to explore digital currency at all.

BLOOM and Cross-Border Settlement
In October 2025, MAS launched BLOOM (Borderless and Ledger-based Open Orchestration of Money), extending Singapore’s settlement capabilities to cross-border tokenised asset exchange. BLOOM develops the settlement-asset layer needed for tokenised assets to be exchanged with real-time finality across jurisdictions.
MAS also signed a Memorandum of Understanding with Deutsche Bundesbank on tokenisation and cross-border settlement, signalling that Singapore’s digital currency infrastructure is being designed for international interoperability from the outset.
In November 2025, MAS published an Operational Guide for Tokenized Funds, providing fund managers, custodians, and service providers with a shared framework for governance, NAV calculation, investor onboarding, and compliance. This guide moves tokenised finance from experimentation to standardised commercial operation.
What This Means for Fintech Platforms
Singapore’s approach creates a structured environment for fintech and digital asset platforms to build on. The key implications:
Wholesale CBDC as settlement asset - platforms that facilitate interbank or institutional transactions can potentially leverage CBDC for atomic settlement, reducing counterparty risk and settlement times.
PBM integration - platforms offering trade finance, escrow, or conditional payment services can build on MAS’s programmable money protocol rather than creating proprietary solutions.
Regulatory clarity - MAS’s planned stablecoin legislation (expected 2026) will provide a clear framework for stablecoin issuers operating in Singapore, complementing the existing Payment Services Act licensing regime.
For Aerapass, headquartered in Singapore and licensed across six jurisdictions, these developments align directly with the platform’s cross-border payment and multi-asset settlement capabilities. As wholesale CBDC and tokenised assets move from pilot to production, platforms with existing compliance infrastructure and multi-rail connectivity are best positioned to integrate.
Summary
Singapore has taken an infrastructure-first approach to digital currency through Project Orchid, building modular capabilities - wholesale CBDC settlement, programmable money, tokenisation infrastructure, and cross-border settlement via BLOOM - rather than rushing to deploy a retail digital dollar. This deliberate strategy positions Singapore’s financial system to activate digital currency features as commercial demand and policy requirements justify it, creating a structured environment for fintech platforms to build on regulated, interoperable infrastructure.
Frequently Asked Questions
Q: What is Project Orchid Singapore MAS?
Project Orchid is the Monetary Authority of Singapore’s multi-year initiative to design and develop the infrastructure for a digital Singapore dollar. It consists of four pillars: a settlement ledger (SGD Testnet) for settling tokenised financial assets using wholesale CBDC, Purpose Bound Money (PBM) for programmable spending conditions, a tokenisation bridge connecting tokenised assets to existing payment rails, and a name service providing an identity layer for digital currency transactions.
Q: What is the difference between Singapore’s wholesale CBDC and a retail CBDC?
Singapore’s wholesale CBDC is designed for interbank and institutional settlement - in 2025, DBS, OCBC, and UOB used it to settle overnight lending on a shared ledger, with transactions recorded in official books and regulatory filings. A retail CBDC would be a digital currency used by consumers for everyday transactions. MAS has stated there is “no urgent need” for a retail CBDC in Singapore, given that PayNow, FAST, and widespread card acceptance already serve consumer payment needs effectively.
Q: What is Purpose Bound Money and how does programmable digital currency work?
Purpose Bound Money (PBM) allows the creator of a digital payment to specify conditions on how the money can be used - effectively programmable spending rules embedded in the currency itself. MAS has overseen trials with Amazon and HSBC for merchant financing, Grab, Ant International, and Fazz for consumer and merchant payments, and OCBC and UOB for testing interchangeability of digital tokens between banks.
Q: What is BLOOM and how does it support cross-border settlement?
BLOOM (Borderless and Ledger-based Open Orchestration of Money) was launched by MAS in October 2025 to extend Singapore’s settlement capabilities to cross-border tokenised asset exchange. BLOOM develops the settlement-asset layer needed for tokenised assets to be exchanged with real-time finality across jurisdictions. MAS also signed a Memorandum of Understanding with Deutsche Bundesbank on tokenisation and cross-border settlement as part of this initiative.
