Given the bank’s global presence and the adoption of the BCBS framework in some jurisdictions, the most crucial consideration for the bank’s risk management strategy is to comply with the strictest regulatory standards to maintain capital adequacy. Specifically:

• Under the BCBS framework, unbacked crypto assets are subject to a 1,250% risk weight, requiring full capital coverage due to their high volatility and lack of intrinsic value.
• Failing to apply this standard could jeopardize the bank’s regulatory compliance and financial stability in jurisdictions where these rules are enforced.

A is incorrect: Internal models are not sufficient for unbacked crypto assets under the BCBS framework, as the 1,250% risk weight is mandatory. Relying on internal models could lead to non-compliance with regulatory standards in jurisdictions that enforce the BCBS rules.

C is incorrect: Pooling resources may reduce operational burdens, but it does not directly address the capital adequacy and regulatory compliance challenges tied to unbacked crypto assets. Shared custody also does not alleviate the risk weight requirement imposed by the BCBS framework.

D is incorrect: While ring-fencing could limit regulatory spillover between jurisdictions, it introduces operational and reputational risks. Additionally, it does not address compliance with BCBS standards in jurisdictions where they are already enforced.
