The Monetary Authority of Singapore has issued a consultation paper proposing a principle-based alternative to the Basel Committee’s restrictive capital treatment of cryptoassets on permissionless blockchains, creating a structured pathway for qualifying stablecoins and tokenized assets to receive lower capital requirements at Singapore banks. The proposal, published as Consultation Paper P009-2026, represents a meaningful departure from the global standard that had effectively barred major stablecoins from favourable prudential treatment at the institutional level.
The move follows sustained industry pushback against MAS’s earlier March 2025 consultation, which would have imposed a 1,250% risk weight on any cryptoasset held on a public, permissionless blockchain, a threshold critics described as prohibitive, technology-discriminatory, and inconsistent with Singapore’s ambitions as a regulated digital asset hub.
Key Facts At A Glance
- MAS published Consultation Paper P009-2026 on April 17, 2026, proposing a principle-based prudential framework for cryptoassets on permissionless blockchains; the consultation closes May 18, 2026.
- Under the prior Basel Committee standard, cryptoassets on permissionless blockchains attracted a 1,250% risk weight, the highest classification in the Basel capital framework, making it capital-prohibitive for banks to hold major stablecoins including USDC and USDT.
- The April 2026 paper proposes that qualifying permissionless cryptoassets may be reclassified as Group 1 assets, eligible for the same capital treatment as tokenized traditional assets and regulated stablecoins, provided banks can demonstrate adequate risk mitigation.
- During an interim period, locally incorporated Singapore banks face a Group 1 exposure cap of 2% of Tier 1 capital and an issuance cap of 5% of Tier 1 capital; foreign bank branches face tighter limits of 0.2% of total branch assets for exposures and 1% for issuances.
- Banks may immediately adopt the proposed framework without waiting for the final rules, subject to the interim caps and a requirement to notify MAS at least one month in advance.
- The final cryptoasset prudential framework is not expected to take effect before January 1, 2027.
- The consultation is MAS’s second on this topic; the first, Consultation Paper P003-2025 from March 2025, proposed a January 1, 2026 implementation date that was deferred following widespread industry objection.
- Industry bodies including the Asia Securities Industry and Financial Markets Association submitted formal responses to the 2025 consultation, arguing the permissionless blockchain treatment was punitive and not technology neutral.
The Problem The Consultation Addresses
The Basel Committee on Banking Supervision published its cryptoasset prudential standards in 2022, sorting digital assets into two capital buckets. Group 1, covering tokenized traditional assets and regulated stablecoins with effective stabilization mechanisms on permissioned networks, received capital treatment broadly aligned with conventional financial instruments. Group 2 attracted a 1,250% risk weight, the highest classification in the Basel framework.
The critical fault line was blockchain type. Under Basel’s 2022 standard, any asset operating on a public, permissionless network was automatically excluded from Group 1, regardless of its design, reserve quality, or risk controls. This categorically barred major stablecoins including USDC and USDT, which operate on permissionless blockchains, from favourable capital treatment at bank level. For a jurisdiction that passed its landmark stablecoin regulatory framework in August 2023 and has spent years positioning itself as a regional hub for digital asset innovation, this would have placed Singapore banks in a structurally disadvantaged position relative to competitors in other markets.
MAS’s first consultation, published in March 2025, proposed implementing the Basel standards with a January 1, 2026 effective date. Industry respondents pushed back with formal submissions, arguing the framework was not technology neutral and would effectively prohibit Singapore banks from meaningfully participating in stablecoin and tokenized asset markets that are growing at scale globally.
What MAS Is Now Proposing
Consultation Paper P009-2026 addresses the permissionless blockchain question directly. The core proposal is a principle-based alternative that replaces the Basel Committee’s binary technology classification with a risk-assessment model. Under the proposed approach, a bank may classify a permissionless cryptoasset as Group 1, and benefit from the lower capital treatment associated with that classification, if it can affirmatively demonstrate that the risks specific to permissionless blockchains have been adequately mitigated.
MAS identifies four categories of risk that banks must address: the reliability of the underlying network; whether transactions are final and legally enforceable; the governance and control structure of the system; and whether financial crime risks, including AML and CFT exposure, can be effectively managed. The paper provides deeming provisions, meaning specific safeguards that if met would be treated by MAS as satisfying the principle-based requirements. These include the absence of concentration of control among validator nodes, monitoring and dispute resolution mechanisms, a clearly defined point of transaction finality, independent audits of smart contracts, and controls restricting participation to verified users.
MAS has been explicit that this is not a relaxation of prudential standards. The regulator states it is introducing a conditional pathway for certain assets to qualify for more favourable treatment, within tightly defined limits. The interim exposure and issuance caps are structured to allow meaningful participation in stablecoin and tokenized asset markets while containing the aggregate risk to Singapore’s banking system during the period before the final framework is settled.
Implications For Singapore’s Digital Asset Sector
The practical effect of the April 2026 proposal, if adopted, is that Singapore banks would be able to hold qualifying stablecoins and participate in tokenized asset markets without the 1,250% risk weight rendering such activity economically unviable. The 2% and 5% Tier 1 capital caps are modest relative to the balance sheet size of Singapore’s major banks, but sufficient to support substantive stablecoin custody, settlement, and issuance activity.
For stablecoin issuers already licensed or operating under MAS frameworks, including those holding Major Payment Institution licences under the Payment Services Act, the proposal changes the calculus around bank partnerships. If Singapore banks can engage with Group 1-eligible stablecoins without punitive capital charges, the commercial case for bank-integrated stablecoin products strengthens considerably.
The consultation also carries relevance beyond Singapore. Global implementation of the Basel cryptoasset standards remains fragmented. The United States, the United Kingdom, and the European Union have each taken different approaches, and implementation timelines remain uncertain across major jurisdictions. Singapore’s principle-based alternative, if finalized, could influence how other regulators approach the same permissionless blockchain question.
