The SEC has proposed a new crypto custody rule under the Investment Advisers Act and the Investment Company Act that would clarify how registered investment advisers and regulated funds can hold client crypto assets. The framework would permit advisers to self-custody crypto only in limited circumstances, such as when they can document that no eligible third party custodian exists. It would also impose strict requirements for key security, segregation of client holdings, and multi-person approval for transfers.

It would explicitly allow state chartered trust companies, and in some versions regulated broker dealers, to act as qualified crypto custodians if they meet safeguarding, audit, and customer protection standards. Several reports note that this proposal replaces a more restrictive 2023 Safeguarding Rule that was withdrawn in 2025 after criticism that it made crypto custody nearly impossible for advisers.

Today many advisers avoid direct crypto exposure because it is unclear which arrangements count as qualified custody for digital assets. The new proposal aims to remove that uncertainty and widen investor access, letting asset managers and hedge funds hold Bitcoin and other crypto directly rather than only through ETFs or structured products. Analysts point out that clearer custody rules could unlock large pools of adviser managed capital, with initial flows most likely into assets that already have robust institutional custody, such as Bitcoin and Ethereum.

Smaller or more exotic tokens may still face limits because they will only be available where custodians support them, and self-custody is constrained by cost and compliance burdens. Custody providers, state trust companies, and some broker dealers could see new business if they qualify, while less regulated custodians may lose market share. If this rule is finalized, the key practical question will be which custodians support which coins, since that will largely determine what advisers can offer clients.

The custody framework is only a proposal. Public comments will be open for about 60 days after Federal Register publication, after which the SEC can revise, narrow, or even withdraw the rule before a final vote. The initiative comes after the CLARITY Act stalled in the Senate, so the SEC and CFTC are pushing ahead with rulemaking under existing authority, including separate proposals on token offerings and tokenized stocks.

Key uncertainties include how strict the final requirements for self-custody and state trust companies will be, whether broker dealers are widely included, and how global regulators respond. If standards are very tight, the practical easing could be modest and concentrated in a few blue chip assets. If the SEC is more flexible, advisers’ crypto menus could broaden, but compliance and audit costs will still rise.

The SEC’s move does not instantly liberalize crypto custody, but it starts to replace ambiguity with a concrete, if demanding, framework for advisers and funds. The real impact will depend on the final rule text and on which custodians step up to support specific assets, with large cap coins best positioned to benefit and smaller tokens still dependent on infrastructure and regulatory comfort.
