In a watershed moment for the integration of traditional finance and digital assets, the Monetary Authority of Singapore (MAS) has officially unveiled a proposal to drastically reduce the capital requirements for banks interacting with public, permissionless blockchains. Released on April 17, 2026, the newly published consultation paper represents one of the most forward-thinking regulatory pivots by a major global financial hub, directly challenging the punitive capital constraints previously standard across the global banking sector.
For years, institutional engagement with public blockchain networks—such as Ethereum or Solana—has been severely bottlenecked by international prudential standards. Following the framework established by the Basel Committee on Banking Supervision, global regulators have largely categorized digital assets on public ledgers as high-risk “Group 2” assets. This classification carries a prohibitive 1,250% risk weight, effectively requiring financial institutions to hold one dollar of capital for every dollar of digital asset exposure. For most banks, this made the tokenization of assets or the issuance of stablecoins on public networks economically unviable.
The new MAS framework shatters this paradigm. Acknowledging that the “one-size-fits-all” approach is no longer technology-neutral in the face of rapidly advancing risk mitigation technologies, Singapore’s financial watchdog is proposing a pathway for certain digital assets—specifically tokenized traditional financial assets and fully backed non-algorithmic stablecoins—to qualify for the highly coveted “Group 1” prudential treatment. By lowering the risk weights to align with traditional financial instruments, MAS is opening the floodgates for banks to actively deploy infrastructure on public blockchain networks.
The Four Pillars of Institutional Risk Mitigation
While the regulatory relief is substantial, it is not unconditional. MAS has explicitly outlined that banks wishing to leverage the Group 1 classification must empirically demonstrate that the inherent risks of permissionless networks have been adequately mitigated. The April 2026 proposal introduces a principle-based framework centered on four core pillars of compliance.
First, institutions must establish robust Governance frameworks. Banks are required to maintain clear, accessible documentation regarding the underlying protocol’s governance arrangements, ensuring that decision-making processes, protocol upgrades, and network modifications can be monitored and assessed for risk.
Second, the framework emphasizes Technology and Resilience. Financial institutions must prove that the public blockchain systems they engage with are technically reliable. Crucially, banks must have contingency plans demonstrating that they can maintain operational resilience and recover asset records even in the event of a catastrophic network failure or protocol-level disruption.
Third, MAS highlights the necessity of Settlement Finality. In traditional finance, settlement finality is legally absolute. On public blockchains, finality is often probabilistic. Banks must implement mechanisms—either technological or legal—to ensure that transactions executed on permissionless networks are final, accurate, and legally enforceable under Singaporean law.
Finally, and perhaps most importantly, the proposal mandates rigorous Financial Crime (AML/CFT) safeguards. Because public blockchains allow anonymous and pseudonymous participation, banks must deploy highly effective identity verification protocols, such as whitelisted wallets or zero-knowledge proof compliance layers, to mitigate money laundering and terrorism financing risks.
Calculated Exposure Limits During the Transition
To prevent systemic risk during the initial rollout of this new capital regime, MAS has introduced strict, temporary exposure caps. These limits are designed to throttle the volume of assets that qualify for the preferential Group 1 treatment, effectively creating a sandbox environment for institutional integration.
For locally incorporated banks in Singapore, exposure to Group 1 digital assets on public blockchains will be capped at 2% of the institution’s Tier 1 capital. For foreign bank branches operating within the city-state, the limits are even tighter: total exposure is capped at 0.2% of the branch’s total assets, while actual digital asset issuances are capped at 1% of total assets.
It is important to note that these caps do not constitute an outright ban on holdings above the limit. Instead, any exposure exceeding these thresholds will automatically revert to the punitive Group 2 (1,250%) risk weighting. Regulators have signaled that these caps will be closely monitored and potentially expanded as banks demonstrate a consistent track record of safely managing public blockchain infrastructure.
Contextualizing Singapore’s 2026 Crypto Strategy
The April 17 consultation paper is not an isolated policy shift; it is the capstone of Singapore’s broader 2026 digital asset strategy. Over the past three years, the city-state has systematically built a comprehensive regulatory perimeter to position itself as the undisputed leader in institutional crypto finance in the Asia-Pacific region.
Earlier this year, Singapore’s standalone stablecoin regime became fully operational, mandating strict reserve requirements and redemption timelines for issuers of SGD and G10-pegged stablecoins. Concurrently, MAS has continued its aggressive licensing of Digital Payment Token (DPT) service providers under the Payment Services Act. As of late April 2026, over 36 platforms—including global heavyweights like Coinbase, Crypto.com, and OKX—have secured full operational licenses.
Furthermore, this capital requirement relaxation dovetails perfectly with MAS’s 2026 tokenization pilot. The central bank recently announced a groundbreaking initiative to test the issuance of tokenized government bills, leveraging a wholesale Central Bank Digital Currency (CBDC) for on-chain settlement. By lowering the capital barriers for private banks, MAS is effectively ensuring that the private sector is fully capitalized and ready to interface with this new sovereign tokenized infrastructure.
Looking Ahead: The Global Ripple Effect
The public consultation for the new Group 1 capital guidelines will remain open for industry feedback until May 18, 2026. The response from global financial institutions operating in Singapore is expected to be overwhelmingly positive, with many banks likely to submit aggressive rollout plans for tokenized asset platforms.
The implications of this policy extend far beyond Singapore’s borders. By breaking ranks with the conservative Basel Committee guidelines and providing a viable economic pathway for banks to use public blockchains, MAS is forcing a global regulatory conversation. Jurisdictions in Europe, the United States, and neighboring Asian markets will undoubtedly be watching closely. If Singaporean banks can successfully and securely deploy tokenized assets on public networks without triggering systemic risks, the “Singapore Model” may very well become the global standard for institutional crypto regulation by the end of the decade.

The Group 1 reclassification for tokenized treasuries and non-algo stablecoins is huge. This is how you get banks to actually use public chains instead of private permissioned networks that nobody wants.
