Singapore Tokenization Regulation: MAS, PSA, and Project Guardian

Overview

Singapore has positioned itself as the world’s leading test environment for institutional tokenization, combining a credible regulatory framework with the Monetary Authority of Singapore’s (MAS) active facilitation of industry pilots. The regulatory infrastructure rests on two legislative pillars: the Payment Services Act (PSA), which governs digital payment token services, and the Securities and Futures Act (SFA), which governs capital markets products — including security tokens. The Precious Metals (Prevention of Money Laundering and Terrorism Financing) Act and the applicable provisions of the MAS Act complete the framework.

Critically, Singapore’s approach integrates regulatory development with live market testing. Project Guardian, launched in 2022 and expanded significantly through 2023–2024, has moved tokenized asset pilots beyond proof-of-concept into real-money, regulated environments. The resulting supervisory experience gives MAS a depth of practical regulatory knowledge that no other single regulator can match in this domain.

Primary Regulator: MAS

The Monetary Authority of Singapore functions as Singapore’s central bank, financial sector regulator, and financial intelligence unit coordinator. MAS has jurisdiction over the full financial services ecosystem — banking, insurance, capital markets, payment services, and financial advisers — and has statutory authority to issue binding notices and guidelines under each relevant act.

MAS’s approach to digital assets is explicitly dual: it has signaled that speculative retail crypto activity is not welcome in Singapore (banning retail crypto advertising in public spaces from 2022), while simultaneously facilitating institutional tokenization through Project Guardian and bespoke engagement with supervised financial institutions.

Payment Services Act: MPI License

The Payment Services Act 2019 (PSA), substantially amended in 2021 to expand scope and capital requirements, establishes the licensing framework for digital payment token (DPT) services in Singapore. The PSA categories relevant to tokenization:

Major Payment Institution (MPI) License: Required for entities providing DPT services (buying, selling, or facilitating exchange of DPT) where transaction volumes exceed specified thresholds, or for entities providing e-money or stored value facility services. An MPI license holder may also provide account issuance, domestic money transfer, cross-border money transfer, merchant acquisition, and money-changing services.

Capital requirements for an MPI license:

• DPT-only operations: S$250,000 minimum paid-up capital
• Combined DPT and e-money operations: S$500,000 minimum paid-up capital

In addition to minimum capital, MPI holders must maintain working capital sufficient to meet liabilities and must segregate client assets from corporate assets with safeguards equivalent to trust arrangements.

Standard Payment Institution (SPI) License: For smaller DPT service providers below monthly transaction thresholds of S$3M (per payment service) or S$6M (in aggregate). Lower capital requirements (S$100,000) and reduced operational requirements, but subject to same AML/KYC obligations as MPI holders.

Exemptions: Digital asset businesses whose primary business is DPT dealing (not payment services) and that deal exclusively on proprietary basis may qualify for exemptions from PSA licensing, but this requires careful legal analysis.

Application Process and Timeline

PSA license applications are submitted to MAS through the PSA licensing portal. MAS typically takes six to nine months to process MPI applications, with additional time for post-grant conditions to be satisfied. Applicants must demonstrate: fit-and-proper shareholders and directors, adequate systems and controls, AML/CFT framework compliance, technology risk management, business continuity planning, and financial resources.

Conditions commonly attached to grants include: restrictions on permitted DPT types, customer base limitations during initial period, monthly transaction reporting, and third-party audit requirements.

Securities and Futures Act: Security Token Framework

Tokens that constitute capital markets products under the SFA — specifically, units in collective investment schemes, securities, or securities-based derivatives — are subject to the full SFA licensing and product registration framework, regardless of their technical form.

For tokenized securities, the relevant SFA authorizations are:

• Recognized Market Operator (RMO) or Approved Exchange: Required to operate a platform on which security tokens are traded. MAS has licensed several digital asset exchanges as RMOs with specific security token permissions
• Capital Markets Services (CMS) License: Required for dealing in capital markets products, fund management, and providing custodial services. Security token managers and broker-dealers require CMS licenses
• Prospectus or Offer Information Statement: Public offers of security tokens above the prescribed thresholds require prospectus registration with MAS, unless an exemption applies (sophisticated investor, private placement to 50 or fewer persons, or institutional investor exemptions)

MAS has issued guidance that the same legal principles apply to tokenized securities as to traditional securities — the digital wrapper does not affect the underlying regulatory classification.

Project Guardian: Institutional Tokenization

Project Guardian, launched by MAS in May 2022 as a collaborative initiative with the Bank for International Settlements’ BIS Innovation Hub, has grown into the world’s most significant regulatory sandbox for institutional tokenization. As of 2024, over 15 real-money pilots have been conducted by global financial institutions under MAS supervisory oversight.

Participating institutions and pilots include:

• DBS Bank, JPMorgan, and SBI Digital Asset Holdings: Tokenized government bond trading via Project Guardian’s open, interoperable network
• HSBC and Marketnode: Tokenized bond issuance and distribution
• Franklin Templeton: Tokenized money market fund integrated into institutional platforms
• BlackRock: BUIDL tokenized Treasury fund (launched March 2024, reached S$1.7B AUM) — structured under applicable fund regulations with MAS engagement
• Standard Chartered and Linklogis: Tokenized trade finance assets
• UBS Asset Management: Tokenized money market fund in Variable Net Asset Value structure

Project Guardian pilots operate under specific supervisory parameters agreed with MAS, allowing participants to test on live regulated markets with defined risk parameters. The learnings from Project Guardian pilots directly inform MAS’s regulatory guidance updates and Singapore’s negotiating positions in international standard-setting bodies.

MAS Stablecoin Framework (August 2023)

MAS published its finalized stablecoin regulatory framework in August 2023, establishing requirements for Single-Currency Stablecoins (SCS) — stablecoins pegged to SGD or G10 currencies — issued in Singapore. Key requirements:

• Reserve backing: 1:1 high-quality liquid assets (cash, bank deposits, short-dated government securities)
• Capital: Issuer must maintain minimum S$1 million or 50% of annual operating expenses, whichever is higher
• Redemption: Par value redemption within five business days of request
• Disclosure: Monthly reserve composition attestation and annual audited reserve report
• Licensing: MAS recognition as “MAS-regulated stablecoin” requires specific application; designation distinct from PSA licensing

This framework positions Singapore’s stablecoin regime as one of the world’s most developed, providing institutional-grade certainty for stablecoin use in tokenized settlement infrastructure.

FATF Travel Rule (June 2023)

Singapore implemented the FATF Travel Rule for digital payment token service providers from June 2023, with a threshold of S$1,500 (approximately USD 1,100). DPT service providers must collect, verify, and transmit originator and beneficiary information for transfers at or above this threshold.

MAS has approved several Travel Rule compliance solutions for use by licensed DPT service providers, including Notabene and Sygna Bridge, providing a pre-approved technology pathway for compliance.

AML/KYC Requirements

DPT service providers in Singapore are subject to MAS Notice PSN02 (Measures to Counter Money Laundering and Countering the Financing of Terrorism) and MAS Notice PSN01 (e-money). Key requirements:

• CDD: Full KYC at onboarding; simplified CDD for low-risk circumstances; EDD for PEPs and high-risk jurisdictions
• Ongoing monitoring: Transaction monitoring calibrated to customer risk profile; automated alert thresholds
• Suspicious Transaction Reports (STRs): Filed with the Suspicious Transaction Reporting Office (STRO) under the MAS Act
• Source of funds: Required for transactions above S$20,000 and for high-risk customers
• Sanctions screening: MAS-designated entities list, UN consolidated list, and OFAC screening required in real-time

Compliance Checklist: Singapore Tokenization Operations
