SAB 122: The key that unlocks institutional crypto custody

Written by Jeff Rundlet | February 4, 2025

A major regulatory barrier to institutional crypto adoption is gone - regulated entities are no longer required to classify custodied crypto assets as liabilities on their balance sheets. 

On January 23, 2025, the SEC issued Staff Accounting Bulletin No. 122 (SAB 122), revoking the controversial guidelines outlined in SAB 121, opening the door for traditional financial institutions to scale their crypto custody operations.

What was SAB 121 and why was it controversial?

Issued in March 2022, SAB 121 introduced strict reporting and risk assessment requirements for financial institutions holding cryptocurrency on behalf of clients. The most significant and widely criticized provision required institutions to classify custodied crypto assets as liabilities on their balance sheets.

This meant that banks and financial firms had to allocate significant reserve capital to back these positions, making crypto custody an unappealing, capital-inefficient business model. As a result, most traditional financial institutions avoided offering crypto custody, leaving the space dominated by crypto-native custodians.

While SAB 121 aimed to enhance oversight, critics argued that it deviated from standard accounting practices, stifled competition, and pushed market participants toward riskier, largely unregulated custodians. It also limited the choice of custodians, heightening concentration risk and increasing systemic vulnerabilities.

How SAB 122 changes crypto custody for financial institutions

SAB 122 removes the requirement for banks to classify client-held cryptocurrencies as balance sheet liabilities, eliminating one of the biggest barriers to scaling crypto custody. This shift makes it far more viable for regulated financial institutions to offer custody services.

Of course, institutions must still meet key reporting and risk assessment obligations, including:

  • Maintaining disclosure and transparency around custodial risks.
  • Complying with established accounting frameworks, such as FASB ASC 450-20.
  • Providing regular financial reporting on crypto holdings.

By taking a more balanced approach, SAB 122 enables broader institutional participation in the U.S. crypto market while maintaining necessary safeguards. The new rule applies retrospectively for annual periods beginning after December 15, 2024, though firms may adopt it earlier to align past financial statements and ease the transition.

The future: a more competitive institutional crypto market

With SAB 122 replacing SAB 121, the institutional landscape for crypto is transforming. The removal of punitive balance sheet requirements means:

  • Banks and traditional financial institutions can now compete in crypto custody, increasing market diversity and reducing reliance on crypto-native custodians.
  • The U.S. aligns more closely with global regulatory frameworks like MiCA (EU) and VARA (Dubai), creating more clarity for institutional participants.
  • Institutional demand for enterprise-grade data, reporting, and compliance tools will surge as more regulated firms enter the space.

This newfound competitiveness in custodial product capital efficiency creates a major opportunity for fast moving market participants. However, building the data, accounting and reporting infrastructure required is complex and time-intensive. Entities considering such offerings will have to decide between self building, which could take years depending on complexity, or integrating dedicated third-party back-office solutions such as Cryptio

How Cryptio supports this evolution

Self building comes with high upfront and ongoing costs, but the bigger risk is lost market share due to delays in time to market.

Back-office solutions provide a much faster path to market - for instance Cryptio already provides the end-to-end data, accounting, and regulatory compliance solutions needed to navigate the complexities of the evolving crypto space.

Our latest platform iteration, Bedrock, offers enterprises:

  • Unmatched data accuracy: data sourced from proprietary indexers and self-run nodes, combinable with off-chain data from internal databases, ledger systems and banks for full and accurate end-to-end cover.
  • Full auditability: through daily reconciliation of on and off-chain wallets on a scale of 1B+ transactions across 100M+ wallets monthly.
  • Peace of mind in regulatory compliance: through tooling to help institutions deal with common issues such as segregation of funds in co-mingled omnibus wallets, alongside seamless ERP integrations and automatic reporting for MiCA, VARA, SEC and common reporting standards.

A watershed moment

SAB 122 represents a watershed moment for crypto’s integration into traditional finance. With regulatory barriers easing, banks, custodians, and asset managers can finally enter the space at scale. This shift will not only drive institutional adoption via increased offerings of custodial crypto products, but also reshape the financial infrastructure underpinning digital assets.

Speed is everything in this new era of regulated finance. The faster you develop and integrate the right accounting and reporting infrastructure, the stronger your first-mover advantage. Cryptio provides the foundation and expertise to get you there—faster.
