The U.S. Securities and Exchange Commission (SEC) has put forward a proposal that would directly govern how registered investment advisers and investment funds must handle the custody of crypto assets under existing federal securities law. The move would extend the established qualified-custodian framework into digital asset holdings for the first time through formalized rulemaking.

Published through the SEC, the proposal targets a compliance gap that has persisted as institutional adoption of crypto assets has accelerated: federal securities rules governing custody were written for traditional financial instruments and have never been explicitly applied to digital assets held on behalf of clients or fund investors.

What the SEC Crypto Custody Proposal Would Address

Under federal securities law, custody refers to the physical or electronic possession of client funds or securities, and registered advisers and funds that carry this responsibility must meet specific safekeeping standards. The SEC proposal would extend those requirements to crypto assets, requiring advisers and funds to demonstrate how digital holdings are held, segregated, and protected under the qualified-custodian standard.

Key points:

• The proposal: SEC rulemaking to define how crypto assets must be custodied under federal securities rules
• Affected parties: Registered investment advisers and investment funds holding crypto on behalf of clients
• Regulatory question: Whether existing qualified-custodian requirements apply to, or must be adapted for, digital asset holdings

Investment advisers registered with the SEC are currently subject to the Custody Rule under the Investment Advisers Act, which mandates that client assets be held by a qualified custodian, typically a bank, broker-dealer, or trust company. The open question the proposal targets is whether crypto-native custodians, self-custody arrangements, or smart-contract-based vaults can satisfy that standard, or whether new categories of qualified custodians must defined.

Investment funds face a parallel question under the Investment Company Act, where portfolio assets must also meet custody standards. The SEC's proposal would give both adviser-managed accounts and fund structures a defined compliance path, replacing the current patchwork of no-action letters and staff guidance with binding rules. The agency has reviewed related structures in the broader digital asset space, including its ongoing examination of exotic crypto fund vehicles, where custody of underlying assets has been a recurring issue.

Why the Proposal Matters for Crypto Asset Custody

The practical compliance questions the proposal would force advisers and funds to answer are significant. Firms would need to assess whether their current custodial arrangements, many of which rely on crypto-native platforms rather than traditional financial institutions, meet any new qualified-custodian definition the SEC codifies.

The proposal stage is distinct from a final rule. Until the SEC completes its rulemaking process, including a public comment period and any subsequent revisions, no new legal obligations attach, and advisers and funds operating under existing guidance are not automatically out of compliance while the proposal is pending. The SEC's comment-period process on related crypto product proposals has historically drawn extensive input from both institutional participants and crypto-native firms, suggesting this rulemaking will attract similar scrutiny.

Items to monitor as the proposal advances include how the SEC defines a qualified custodian for crypto assets, whether on-chain custody mechanisms receive any formal recognition, and what transition period, if any, applies to advisers and funds already holding digital assets. The intersection of on-chain governance infrastructure with SEC-regulated custody frameworks also raises questions for decentralized protocols that currently provide custodial services to institutional clients, a segment where regulatory clarity has been absent. Prior SEC activity around crypto ETF structures and their asset custody requirements offers a partial precedent for how the agency may approach qualified-custodian definitions in a final rule.
