The Monetary Authority of Singapore (MAS) has released a consultation paper proposing a fundamentally new approach to the prudential treatment of cryptoassets issued on public, permissionless blockchains — a move industry observers are calling a “gamechanger” for how banks engage with digital assets in the region.
Published on 17 April 2026, the consultation marks a decisive shift from Singapore’s historically conservative, blanket capital treatment of cryptoassets toward a flexible, principle-based framework. Under the proposed rules, banks would be permitted to classify and treat qualifying permissionless cryptoassets as “Group 1 cryptoassets” — a more favourable capital classification — provided they can demonstrate adequate risk mitigation across four key pillars: governance, technology, settlement finality, and anti-money laundering/counter-financing of terrorism (AML/CFT) compliance.
“MAS is not proposing to relax prudential standards,” the regulator clarified in the paper. “Rather, it is introducing a pathway for certain cryptoassets to be treated more favourably, provided risks can be demonstrated to be adequately mitigated and within defined limits.”
The proposal sets strict interim exposure and issuance caps to manage systemic risk during the transition period. Locally incorporated banks would face a 2% exposure cap and 5% issuance cap, both measured as a percentage of Tier 1 capital. Singapore branches of foreign banks would be subject to tighter limits of 0.2% exposure and 1% issuance, calculated against total assets. Any exposure exceeding these caps remains subject to MAS’s default conservative capital treatment.
Key safeguards under the framework include a diversified validator set with documented governance arrangements, systems guaranteeing transaction record accuracy, operational resilience even if the underlying blockchain fails, and mechanisms to verify users or implement effective financial crime safeguards. MAS also provides “deeming provisions” — meeting specified conditions automatically satisfies risk requirements — while allowing banks to propose alternative safeguards subject to regulator approval.
The consultation, which closes on 18 May 2026, invites industry feedback on the adequacy of the principle-based requirements, the inclusion and calibration of AML/CFT provisions, and the necessity of the proposed caps. Industry reaction has been broadly positive, with legal firms such as Bird & Bird describing the proposal as a potential gamechanger for tokenised payments, stablecoin settlement, and broader blockchain-based financial infrastructure in Singapore and the wider ASEAN region.
The reform has significant implications for the broader digital asset ecosystem. Crypto issuers and infrastructure providers must now design products that are “bank-compatible and audit-ready” to capture institutional capital, effectively raising the governance bar across the industry. For Singapore, the framework positions the city-state as a potential global hub for regulated digital asset activity, balancing innovation with the regulator’s stated commitment to financial stability.
