SEC Crypto Custody Proposal Prioritizes Commercial Capabilities Over Regulatory Charters

The U.S. Securities and Exchange Commission (SEC) has proposed new rules for cryptocurrency custody that could significantly alter the competitive landscape by emphasizing commercial capabilities over regulatory charters. The proposal aims to formalize the role of state-chartered trust companies as qualified custodians and, under specific conditions, permit registered investment advisers to self-custody crypto assets when no qualified custodian is available.

This initiative seeks to foster a more competitive market by reducing the exclusivity of regulatory charters as a barrier to entry. Historically, firms like Coinbase, Gemini, and Fireblocks have built regulated custody businesses around trust charters, with Coinbase Custody Trust Company supporting 470 assets. Anchorage Digital obtained a federal charter in 2021. However, the proposed rules would shift the focus from the type of charter to the commercial capabilities of a custodian, such as the breadth of assets supported and the range of services offered.

Shifting Competitive Landscape: Charters vs. Capabilities

The proposed shift is expected to intensify competition. Traditional custody banks, which held over $234 trillion in customer assets globally in 2024, possess advantages like existing client relationships, cash management, and fund accounting that crypto-native firms cannot easily replicate. However, the SEC proposal challenges the notion that being within the traditional bank perimeter should solely determine who can compete in crypto custody. For institutions like BNY, which operates a digital-asset custody platform, and State Street, which has launched its own digital-asset platform, this means they will need to win crypto business based on their capabilities rather than solely on regulatory status.

Impact on Market Participants

Crypto-native firms, while potentially gaining a clearer regulatory path, will still need to persuade institutions to shift assets away from established banks. The proposal could make it easier for them to compete by formalizing their status and potentially broadening their client base. The SEC’s proposal is subject to a 60-day comment period following its publication in the Federal Register. Staff no-action relief for state trust companies has been in place since September 2025, providing an interim opening.

Asset Coverage and Self-Custody: New Dynamics

The proposal includes provisions for investment adviser self-custody, but this option comes with substantial controls and costs. According to the SEC, the specified self-custody requirements could cost an adviser approximately $433,833 annually on average, including an estimated $376,000 for the required internal-control report. These significant fixed costs could limit the self-custody option to firms with sufficient scale to justify the investment, suggesting that for many smaller advisers, paying a qualified custodian may remain the more practical choice.

Asset coverage is emerging as a key competitive differentiator. The rule governing unsupported assets could turn asset coverage into a customer-acquisition tool. If a custodian adds support for a previously unsupported asset, it could create a regulatory incentive for an investment adviser to move that asset onto their platform. This means a custodian’s roadmap for listing new assets becomes a strategic part of their sales approach, influencing their ability to capture a larger share of a client’s portfolio.

Future Outlook and Uncertainties

For crypto issuers, securing support from qualified custodians could become increasingly important for institutional distribution. The evolving custody market suggests that competition will increasingly hinge on factors such as asset coverage, speed of support, the utility of assets after they are deposited, and seamless integration with trading, staking, reporting, and fund administration services.

Several uncertainties remain. The final rules could differ after the comment period concludes. The extent to which smaller advisers will opt for self-custody versus paying for qualified custodians is yet to be determined. Furthermore, the precise impact of these proposed rules on the competitive dynamics between traditional financial institutions and crypto-native firms is still unfolding. The SEC’s proposal challenges the existing framework, pushing the industry toward a future where commercial capabilities and service breadth are paramount in the crypto custody market.
