The Hong Kong Monetary Authority (HKMA) is taking significant steps to align with global banking standards for crypto asset exposures. In February 2024, the HKMA issued a consultation paper on implementing the Basel Committee’s regulatory standards for banks holding crypto assets like stablecoins, tokenized traditional assets, and Bitcoin. This was followed by another consultation in January 2025 regarding proposed amendments to the Banking (Capital) Rules and Banking (Disclosure) Rules.
These developments highlight Hong Kong’s commitment to creating a secure and transparent regulatory environment for digital assets while ensuring financial stability.
Background of the New Regulatory Framework
The Basel Committee on Banking Supervision sets international standards for banking regulation, known as the Basel Framework. As a member, the HKMA is committed to implementing these standards through local legislation.
With the growing adoption of crypto assets, many banks globally are seeking to hold these digital assets for their economic benefits. In response, the Basel Committee released the "Prudential treatment of cryptoasset exposures" in December 2022. This was later incorporated into the Basel Framework as "Cryptoasset exposures" (SCO60), which outlines capital requirements, exposure limits, disclosure rules, and risk management practices for banks holding crypto assets.
SCO60 has undergone several revisions, with the July 2024 update tightening classification conditions for Group 1b crypto assets—qualified stablecoins with effective stabilization mechanisms. The latest version of SCO60 is set to take effect on January 1, 2026.
Following the Basel Committee’s guidelines, the HKMA initiated consultations with the Hong Kong Association of Banks and the Deposit-Taking Companies Association in January 2025. The proposed amendments aim to integrate SCO60 into local regulations, ensuring that banks maintain adequate capital buffers when holding crypto assets.
The HKMA plans to implement the new rules by January 1, 2026, in line with the Basel Committee’s timeline.
Definition of Crypto Assets
Under the Basel Framework, a crypto asset is defined as a private digital asset that relies primarily on cryptography, distributed ledger technology, or similar technologies. A "digital asset" is described as a digital representation of value that can be used for payment, investment, or accessing goods and services. Notably, digital representations of fiat currency are not considered digital assets.
The HKMA’s proposed definition aligns closely with the Basel Framework but omits the term "private." This omission accounts for potential future treatments of central bank digital currencies (CBDCs) and reflects feedback from industry consultations.
Understanding Crypto Asset Exposures
Crypto asset exposure includes both on-balance-sheet and off-balance-sheet exposures. These can be direct, indirect, or synthetic positions involving one or more crypto assets.
The definition is broad enough to cover off-balance-sheet exposures such as recourse asset sales and forward asset purchases involving crypto assets.
Classification of Crypto Assets
Banks must classify crypto assets into specific categories to determine applicable capital and risk management requirements. The Basel Framework and proposed amendments divide crypto assets into two main groups with four subcategories:
Group 1: Tokenized Traditional Assets and Stabilized Crypto Assets
- Group 1a: Tokenized traditional assets
- Group 1b: Crypto assets with stabilization mechanisms (e.g., stablecoins)
Group 2: All Other Crypto Assets
- Group 2a: Crypto assets meeting certain hedging criteria
- Group 2b: High-risk crypto assets, including those without reliable stabilization mechanisms
To qualify for Group 1, a crypto asset must meet four classification conditions:
- Asset Type and Stabilization: Must be a tokenized traditional asset or have a stabilization mechanism linked to a reference asset.
- Legal Certainty: All rights, obligations, and interests must be clearly defined and legally enforceable across all relevant jurisdictions.
- Risk Mitigation: The crypto asset and its underlying network must be designed to minimize operational and technical risks.
- Regulatory Compliance: Entities involved in redemption, transfer, storage, or management must be regulated or adhere to robust risk management standards.
Banks are responsible for continuously assessing crypto assets against these conditions. They must maintain detailed records and may need to submit these to regulators like the HKMA upon request.

Capital and Risk Management Requirements
Group 1a Assets
- Generally subject to the same risk weights as their underlying traditional assets.
- Can serve as recognized collateral if they meet specific criteria.
Group 1b Assets
- Banks must analyze each asset’s structure and identify all potential risks.
- Capital requirements apply to reference asset risks, redemption counterparty risks, and intermediary risks.
- Not eligible as recognized collateral.
Group 2 Assets
- Group 2a: Capital requirements calculated using a simplified standardized approach.
- Group 2b: Subject to a conservative capital treatment with a 1,250% risk weight.
Exposure Limits for Systemically Important Banks (SIBs)
SIBs’ total exposure to Group 2 crypto assets must not exceed 2% of their Tier 1 capital and should generally not fall below 1%. Breaches result in punitive risk weights.
Banks must pre-report classification decisions to the HKMA. New crypto assets are temporarily classified as Group 2b until the HKMA confirms their eligibility for another category. The HKMA retains the right to overturn a bank’s classification decision.
Treatment of Permissionless Blockchain Assets
The Basel Committee has expressed concerns about crypto assets issued on permissionless blockchains. Its December 2023 amendments noted that banks currently lack the ability to mitigate risks associated with these networks effectively.
The HKMA aligns with this view, stating that crypto assets on permissionless blockchains do not qualify for Group 1 classification.
However, industry associations like the Global Financial Markets Association (GFMA) argue that banks have the expertise to manage these risks. They advocate for allowing banks to classify qualifying permissionless blockchain assets as Group 1.
Implications for Stablecoins
The classification conditions impose high standards on stablecoin issuers and arrangements:
- Condition 1: Reserve assets must be sufficient to cover redemptions, even under stress.
- Condition 2: Legal certainty must be established in all jurisdictions where the stablecoin is issued and redeemed.
- Condition 3: The underlying blockchain infrastructure must be transparent and traceable.
- Condition 4: All key service providers must be regulated or adhere to strict risk management standards.
These requirements ensure that stablecoins are robust and reliable, but they also pose significant compliance challenges for issuers.
Conclusion and Next Steps
Hong Kong’s proactive approach to crypto asset regulation demonstrates its commitment to fostering a secure and innovative financial ecosystem. The HKMA’s proposed amendments aim to align local standards with global best practices, ensuring that banks can safely engage with digital assets.
The new rules are expected to take effect on January 1, 2026. Banks and other financial institutions should begin preparing now by enhancing their risk management frameworks and ensuring compliance with the upcoming requirements.

Frequently Asked Questions
What is the Basel Framework?
The Basel Framework is a set of international banking regulations developed by the Basel Committee on Banking Supervision. It aims to strengthen financial stability by establishing minimum capital requirements and risk management standards.
How does Hong Kong’s crypto asset regulation compare to other jurisdictions?
Hong Kong is aligning closely with global standards set by the Basel Committee. This ensures consistency and facilitates cross-border banking operations. Other jurisdictions may have varying approaches, but Hong Kong’s framework is designed to be comprehensive and robust.
What are the key challenges for banks holding crypto assets?
Banks must navigate complex classification requirements, maintain adequate capital buffers, and implement strong risk management practices. They also need to ensure legal certainty and operational resilience for all crypto asset exposures.
How can banks prepare for the new regulations?
Banks should start by reviewing their current crypto asset holdings and assessing them against the new classification conditions. They should also enhance their risk management frameworks and engage with regulators early in the process.
What is the significance of the 1,250% risk weight?
A 1,250% risk weight is a conservative capital requirement applied to high-risk crypto assets. It effectively requires banks to hold capital equal to the full exposure amount, discouraging excessive investments in risky assets.
Are stablecoins considered crypto assets under the new rules?
Yes, stablecoins are classified as crypto assets. Those with effective stabilization mechanisms may qualify for Group 1b, subject to meeting all classification conditions.
