SAB 121 Requirements
Issued in March 2022, SAB 121 requires entities that safeguard crypto assets for platform users to:
- Recognize a liability for the obligation to safeguard assets
- Recognize a corresponding asset on the balance sheet
- Measure both at fair value of the crypto assets
- Provide specific disclosures about risks and obligations
Impact on Financial Institutions
Balance Sheet Effects
SAB 121’s requirement to recognize crypto holdings as both assets and liabilities dramatically increases reported assets, affecting:
- Capital adequacy ratios
- Leverage calculations
- Regulatory capital requirements
Banking Sector Concerns
Traditional banks have largely avoided crypto custody due to SAB 121’s capital implications. The accounting treatment makes custody services economically challenging under current capital frameworks.
Regulatory Developments
Congressional efforts to address SAB 121 have included:
- Bipartisan resolutions to overturn the guidance
- Letters from banking regulators expressing concerns
- Proposed legislation to exempt qualified custodians
Compliance Strategies
Institutions navigating SAB 121 should consider:
- Structuring custody arrangements to minimize balance sheet impact
- Evaluating whether specific arrangements trigger SAB 121
- Monitoring regulatory developments for potential relief
- Working with auditors on implementation questions
Future Outlook
The SEC has faced substantial pressure to modify or withdraw SAB 121. Changes to the guidance could significantly expand institutional crypto custody capacity.
