Singapore's Payment Services Act: Asia's Digital Asset Regulatory Template

The Monetary Authority of Singapore’s Payment Services Act entered into force in January 2020, consolidating Singapore’s previously fragmented payment regulation into a single activity-based licensing framework. Its design principle was technology neutrality: rather than listing specific payment technologies or instruments, the PSA defined the payment services that required licensing based on what those services do — facilitate transfers, issue payment instruments, manage merchant accounts — and applied that definition regardless of the underlying technology. Cryptocurrency exchanges and digital asset services that performed these functions fell within the PSA’s scope.

The PSA created a new regulatory category — Digital Payment Token (DPT) services — specifically for businesses buying, selling, or facilitating the exchange of crypto assets and digital tokens. The DPT category was the first step in Singapore’s comprehensive crypto regulation, and the PSA became the legislative vehicle through which MAS implemented its evolving approach to the sector over the following five years.

The PSA’s Activity-Based Approach

The PSA’s activity-based architecture distinguishes it from jurisdiction-specific crypto legislation that focuses on the asset itself (what the token is) rather than the service (what the firm does with it). A DPT service provider under the PSA is defined by its activities — buying or selling DPTs, providing a platform for exchange, or facilitating transmission of DPTs — rather than by the nature of the DPTs it handles. This means the regulatory framework applies consistently regardless of whether the DPT in question is Bitcoin, Ether, a stablecoin, or a novel token type — provided the firm is performing a DPT service.

MAS issues three types of licence under the PSA relevant to DPT services: a Money-Changing Licence for limited exchange services; a Standard Payment Institution Licence for firms with transaction volumes below specified thresholds; and a Major Payment Institution Licence for larger operators. DPT service providers must obtain one of the latter two licences depending on their size and activity scope. The licensing process requires MAS approval of principal officers and substantial shareholders, assessment of the firm’s AML/CFT framework, evaluation of technology risk management, and satisfaction of capital requirements.

The 2022 Amendments: Post-FATF Travel Rule

The PSA was amended significantly in 2022, with the amendments entering into force in stages. The most important amendment extended the PSA’s licensing requirements to additional DPT activities — including custody of DPTs and facilitating the exchange of DPTs without taking custody — and incorporated requirements for compliance with the FATF Travel Rule for DPT service providers.

The FATF Travel Rule requires that virtual asset service providers include originator and beneficiary information with DPT transfers above specified thresholds — equivalent to the correspondent banking requirements that apply to wire transfers. Implementation requires DPT service providers to collect and transmit customer identity information with each qualifying transfer, raising significant practical challenges around data format standards, counterparty identification, and the treatment of transfers to or from self-hosted wallets. MAS worked with industry through a consultation process on Travel Rule implementation, ultimately specifying threshold requirements and technical standards through its PSN02 Notice.

The 2022 amendments also strengthened MAS’s supervisory powers, giving it clearer authority to impose business restrictions, require compliance improvements, and revoke licences for firms that fail to meet standards. MAS exercised these powers actively in the post-FTX period, imposing business restrictions on several licensed DPT service providers and warning publicly that its regulatory framework was not a guarantee of the safety of any particular platform.

The DTSP Framework: Effective June 30, 2025

The Digital Token Service Provider (DTSP) framework, which became effective June 30, 2025, addressed a significant gap in the PSA’s original architecture: firms incorporated and operating outside Singapore but serving Singapore-resident customers through online platforms. Under the original PSA, such firms were not directly within MAS’s regulatory perimeter — a gap that allowed offshore platforms to access Singapore’s large and sophisticated retail crypto market without the compliance burden of PSA licensing.

The DTSP framework requires firms providing DPT services to Singapore customers from outside Singapore to register with MAS if they are actively targeting Singapore residents — for example, through Singapore-language marketing, Singapore-specific promotions, or other clear indicators of deliberate engagement with the Singapore market. The framework imposes AML/CFT compliance requirements on registered DTSPs, requires them to comply with MAS’s technology risk management standards for Singapore-facing services, and gives MAS authority to take action against non-compliant offshore providers.

MAS’s Policy of Generally Not Issuing DTSP Licences

MAS has been explicit about its approach to the DTSP framework: it will generally not issue DTSP licences to offshore crypto service providers as a mechanism for them to access the Singapore market. The statement reflects MAS’s policy judgment that the primary purpose of the DTSP framework is to impose compliance standards on offshore firms that are already accessing Singapore markets — not to create a new licensing pathway that enables additional offshore firms to do so.

This stance reflects MAS’s broader positioning on retail crypto activity. Singapore’s regulators have been notably cautious about promoting retail crypto investment, repeatedly warning the public about crypto investment risks and declining to encourage the development of Singapore as a retail crypto hub in the way that Hong Kong has explicitly positioned itself. MAS’s comfort with Singapore as a hub for institutional digital asset activity — tokenized bonds, wholesale CBDC experiments, Project Guardian — stands in deliberate contrast to its caution about retail crypto services.

Comparison with Hong Kong’s Hub Strategy

The contrast between Singapore and Hong Kong’s approaches to crypto regulation has become one of the defining policy stories in Asian financial markets. Hong Kong, following its 2022 policy reversal, has explicitly positioned itself as a crypto hub — welcoming retail crypto trading platforms, issuing mandatory VATP licences, and cultivating the political narrative of Hong Kong as Asia’s digital asset centre.

Singapore has declined to compete on those terms. MAS’s Senior Minister Tharman Shanmugaratnam and Managing Director Ravi Menon have both publicly stated that Singapore does not seek to be a crypto trading hub, and that the country’s interest in digital assets is focused on the institutional and infrastructure applications — tokenized assets, digital bond issuance, payment system modernisation — rather than retail speculation. This difference in strategic posture produces different regulatory frameworks: Hong Kong’s is calibrated to attract trading platforms and retail participants; Singapore’s is calibrated to attract institutional innovation while protecting retail investors from its risks. Whether either strategy proves superior will depend partly on how the regulatory and market environments evolve over the next several years.
