MAS Regulatory Framework — Payment Services Act
Singapore's crypto regulatory framework is built on the Payment Services Act 2019 (PSA), which was substantially amended in 2021 and again in 2023 to expand the scope of regulated digital payment token services. The PSA provides MAS with comprehensive powers to license, supervise, and enforce against payment service providers, including crypto asset service providers operating as Digital Payment Token (DPT) service providers.
The PSA defines Digital Payment Token services to include: buying or selling DPTs (exchange services); facilitating the exchange of DPTs (intermediary platforms); transmitting DPTs; providing DPT custodial wallet services; and inducing or attempting to induce any person to enter into an agreement for the provision of DPT services. This broad definition covers virtually all mainstream crypto exchange, wallet, and transfer activities.
MAS has established itself as one of the world's most respected crypto regulators through a combination of clear regulatory guidance, proactive industry engagement, and forward-looking innovation initiatives. MAS's regulatory philosophy explicitly recognises the importance of enabling innovation while managing risks — a balance reflected in initiatives like the FinTech Regulatory Sandbox, Project Guardian (institutional DeFi), and Project Orchid (retail CBDC design).
Singapore's reputation as a trusted financial centre — underpinned by rule of law, judicial independence, and the MAS's own AAA-rated credibility — adds substantial institutional value to a Singapore DPT licence beyond the mere regulatory authorisation. For global institutional counterparties, a MAS DPT licence signals compliance standards equivalent to major Western regulatory jurisdictions.
DPT Service Provider Licence — SPI vs MPI Requirements
The PSA provides for two main DPT licence types: Standard Payment Institution (SPI) and Major Payment Institution (MPI). The distinction is primarily based on monthly transaction volumes, with MPI applicable to larger operations.
In-principle approval: MAS issues In-Principle Approval (IPA) before the final licence, allowing applicants to complete operational setup (banking, systems, hiring) before the licence is formally granted. The IPA stage is a key milestone in the Singapore licensing process.
Sandbox & Innovation — Project Guardian & Orchid
MAS operates the FinTech Regulatory Sandbox, which allows companies to test financial products and services in a live environment with certain regulatory requirements relaxed for a defined period. For crypto businesses with novel business models that might not fit neatly into existing PSA categories, the Sandbox provides a pathway to operate while MAS develops appropriate regulatory treatment.
Project Guardian is MAS's landmark initiative for institutional DeFi and asset tokenisation, launched in 2022 as a public-private partnership with major financial institutions including JPMorgan, DBS Bank, UBS, and Standard Chartered. Project Guardian has produced industry frameworks for tokenised assets, institutional DeFi pools, and cross-border settlement using distributed ledger technology. By 2026, Project Guardian had advanced to testing interoperable digital asset networks across multiple jurisdictions, with MAS as the coordinating authority.
Project Orchid is MAS's ongoing research and design initiative for a Singapore retail CBDC (Central Bank Digital Currency). Unlike China's e-CNY, Project Orchid is focused on programmable money use cases — government benefit disbursements, conditional payments, and voucher systems — rather than a general-purpose retail digital currency. Project Orchid's findings have informed Singapore's stablecoin regulatory framework and MAS's approach to programmable payments.
Stablecoin Regulation 2023 — MAS Single-Currency Framework
MAS published its stablecoin regulatory framework in August 2023, creating a world-leading regulatory structure for single-currency stablecoins (SCS). The framework applies to SCS pegged to the Singapore dollar or to any G10 currency (USD, EUR, GBP, JPY, CAD, AUD, CHF, NOK, SEK, DKK) issued in Singapore.
Key requirements for MAS-regulated stablecoins: reserve assets must be held at par value at all times in high-quality liquid assets (cash, central bank reserves, short-duration government bonds); reserves must be independently audited and attested monthly; issuers must meet MAS minimum capital requirements (higher of SGD 1 million or 50% of annual operating expenses); and issuers must maintain redemption mechanisms allowing holders to redeem at par value within five business days.
Stablecoins meeting all MAS framework requirements may use the designation "MAS-regulated stablecoin" — a significant trust signal for institutional and retail users. By 2026, several stablecoin issuers had obtained MAS regulated stablecoin designation, including both new Singapore-native issuers and established global issuers who established Singapore-regulated entities to access the MAS label.
Retail Restrictions — Consumer Protection Measures
MAS introduced strict retail protection measures for crypto in 2022, following a period of aggressive retail marketing by crypto platforms in Singapore. These measures significantly restrict how DPT service providers can market to and serve retail customers in Singapore.
Prohibited activities for DPT licensees: advertising crypto services in public areas (ATMs, bus shelters, train stations, shopping centres); social media advertising targeting retail audiences; providing credit facilities or margin financing to retail customers for crypto purchases; facilitating payment account funding of crypto purchases via credit cards. These restrictions do not apply to institutional or accredited investor clients.
Required measures: all retail customers must complete a customer risk awareness assessment before accessing DPT services, confirming they understand the risks of crypto investments; retail leverage is restricted; crypto derivatives require MAS approval as capital markets products. These measures reflect MAS's deliberate policy of making Singapore a hub for institutional and sophisticated crypto operations, while limiting speculative retail exposure.
