SEC Crypto Custody Proposal Opens a Self-Custody Path—With a High Bar for Smaller Advisers

The Securities and Exchange Commission has proposed a dedicated custody framework for crypto assets held by registered investment advisers and regulated funds.

The headline change is significant: advisers could use state trust companies as custodians, and in limited cases they could hold client crypto through a form of self-custody.

But the proposal is not a free pass to keep private keys in a desk drawer. The self-custody path comes with technical, governance and review obligations that may be much easier for a large institution to absorb than a small adviser.

In its October 1 announcement, the SEC said the existing custody framework was built for traditional assets and had not kept pace with a multi-trillion-dollar crypto market.

The proposed rules would cover registered investment advisers, registered investment companies and business development companies. They would modernize audit requirements, address broker-dealer custodial services and create a clearer route for funds that want direct crypto exposure rather than a workaround designed for another kind of asset.

The proposal would also recognize eligible state trust companies as permitted custodians. That could widen the field beyond a small group of traditional firms and give crypto-native custody providers a clearer role—provided they meet the proposal’s authorization and safeguarding requirements.

That is a practical change. The private key controlling a crypto asset does not behave like a paper certificate or a conventional account entry.

Losing it can mean losing the asset. Letting a rule acknowledge that technical reality is overdue.

The SEC’s proposal would permit an adviser to self-custody certain client crypto assets only after determining that no permitted custodian is available. That finding would not be permanent.

It would have to be revisited quarterly.

The adviser would also need safeguarding systems that protect key material from loss and unauthorized access. Access would be limited to designated supervised personnel, and a regulated fund’s board would have a role in choosing those people.

Those conditions help explain the tension inside the proposal. It opens a door that the old framework effectively kept shut, yet walking through it may require specialized security staff, documented controls, recurring determinations and board-level oversight.

A global asset manager can spread those costs across billions of dollars. A smaller registered adviser may find that the compliance bill outweighs the benefit of holding crypto directly.

That does not make the proposal anti-crypto. It does mean the competitive impact deserves attention during the comment period.

Commissioner Hester Peirce, who has led the SEC’s Crypto Task Force, described the history of adviser crypto custody as a regulatory roller coaster.

In her statement supporting the proposal, Peirce said compliant custody had often appeared impossible because few traditional custodians offered robust support for a wide range of crypto assets. She welcomed the expansion of custody options and urged market participants to study the lengthy release and comment on it.

That last point matters. This is a proposal, not a final rule.

The public comment period will remain open for 60 days after publication in the Federal Register. The details around permitted custodians, self-custody, audits and operational safeguards can still change.

The SEC has finally put a crypto-specific custody path on paper. The next question is whether the final version can protect private keys without turning direct ownership into a privilege only the biggest firms can afford.
