SEC proposes tailored crypto asset custody rules

TLDR

The SEC has proposed new rules that would let investment advisers and regulated funds hold crypto under a tailored custody framework, but the rules are not yet in effect.

1. The proposal allows limited self-custody of crypto and use of state trust companies, with strict safeguards and audits.
2. If adopted, it could widen access to crypto through advisers and funds, especially for assets supported by qualified custodians.
3. The outcome will depend on a 60-day comment process and how the SEC balances investor protection with practical custody options.

Deep Dive

1. What The SEC Actually Proposed

On 1 Oct 2026, the SEC unveiled a tailored crypto custody framework for registered investment advisers and regulated funds such as mutual funds and business development companies. The rules would amend the Investment Advisers Act and Investment Company Act to recognize crypto-specific custody arrangements, including self-custody in "limited circumstances" and crypto held through state trust companies, alongside banks and broker-dealers as qualified custodians under a clearer framework for digital assets. Public comments will be open for 60 days after publication in the Federal Register, and the package replaces an earlier, more restrictive "Safeguarding" proposal that drew heavy criticism.

2. How It Could Change Access To Crypto

Under the draft, advisers could self-custody client crypto only when they determine no permitted custodian is available for that asset, reassess eligibility quarterly, and move coins to an approved custodian once one exists. They must segregate each clients holdings at separate blockchain addresses, implement strong private key and cybersecurity controls, require at least two authorized people to approve transfers, and obtain independent internal control audits. State trust companies could qualify as custodians if they are formally authorized for crypto, keep client assets segregated, and provide audited financials and control reports. Taken together, this could make it easier for large advisory firms and regulated funds to offer direct Bitcoin and other crypto exposure rather than only via ETFs or structured products, with early access concentrated in assets that major custodians support.

3. Key Risks And What To Watch Next

The proposal still faces debate on investor protection and practical feasibility. Commissioner Mark Uyeda highlighted conflicts when advisers hold client assets, and others have questioned reliance on varied state trust company standards. The operational burden of audits and multi-person key controls may limit how widely self-custody is used, leaving qualified custodians central. Over the next months, the critical signals are industry comment letters, any SEC revisions to definitions of "qualified custodian," and whether the final rule narrows or expands self-custody and state trust eligibility.

Conclusion

If the SEC finalizes these tailored crypto custody rules in a reasonably flexible form, they could materially expand institutional and advised access to crypto while tightening safeguards around how client assets are held. The long-term impact will hinge on the final text and on whether custodians and advisers can meet the new standards without making crypto exposure prohibitively complex or costly.
