BCG Report Places Custody at Core of Banks’ Digital Asset Strategies

TL;DR: Research released by Boston Consulting Group and backed by Ripple contends that a bank’s approach to custody dictates the range of digital asset services it can roll out. The financial upside presented is purely modeled, and the adoption metrics leave out assets sitting on centralized exchanges.

When financial institutions map out an entry into digital assets, their choice of custody provider often shapes what specific products they can ultimately develop.

That thesis forms the core of a report published by Boston Consulting Group on October 22. Funded by Ripple, the study calculates that institutional custody models account for more than 30% of digital assets existing outside of centralized trading platforms.

That distinction is crucial: the percentage does not mean institutions rely on third-party custodians for 30% of the aggregate crypto market. BCG’s metrics factor in both enterprise self-custody and wallet-as-a-service frameworks, which vary widely in terms of operational control and external outsourcing.

The Choice Goes Beyond Who Holds The Keys

According to BCG, banks may require a mix of custody frameworks depending on the exact offerings they wish to bring to market. The findings place heavy emphasis on robust governance, seamless integration, and the capacity to coordinate smoothly across different providers.

Ripple’s interpretation of the study notes that major financial institutions are increasingly licensing proprietary self-custody tech to build client-facing solutions, whereas payment and retail fintechs lean heavily toward wallet-as-a-service alternatives. Furthermore, the firm points to a growing desire for unified control mechanisms spanning multiple custodians.

This reality underscores why selecting a custody model is as much about product architecture as it is about security. Storing assets long-term involves a completely different operational workflow than shifting collateral across various trading venues or clearing a continuous stream of payments. While the underlying key-management infrastructure might remain the same, the approval guidelines and operational workflows will diverge significantly.

Take, for instance, a bank leveraging a stablecoin for transactional payments. Even with a secure signing mechanism in place, the system must clearly define authorizers, spending limits, and conflict-resolution procedures. Cryptographic security alone cannot resolve these fundamental business operations.

A Business-Case Estimate With Clear Limits

An illustrative projection from BCG indicates that a regional bank holding between $200 billion and $300 billion in assets could potentially unlock $80 million to $100 million in profit-and-loss improvement by pairing targeted custody methods with five distinct digital asset use cases. This figure represents a hypothetical projection rather than actual financial results or a guarantee that all similar banks will see identical gains.

The sponsorship context is also important. Ripple provides custody infrastructure and commissioned the study, meaning the report delivers valuable conceptual frameworks while aligning with its own commercial goals to grow the sector.

All of this unfolds against a well-defined regulatory framework. During July 2025, U.S. banking authorities issued a joint reminder stressing that cryptocurrency safekeeping must adhere to established legal, safety, and soundness standards, noting that the guidance introduced no novel regulatory expectations.

Consequently, for banks evaluating tokenized assets, the core operational hurdle is determining which specific controls, integrations, and liabilities correspond to the projected revenue. The most compelling business strategies will demonstrate how individual services generate net profits after factoring in operational expenses and potential risks, rather than relying strictly on broad industry adoption stats.
