SEC proposes crypto custody path for advisers

TLDR

The SEC has proposed formal rules that would clarify how investment advisers and funds can hold crypto assets for clients, including tightly controlled self custody options.

1. The proposal creates a tailored crypto custody framework, adding state trust companies and conditional self custody to the list of ways advisers can safeguard client digital assets.
2. If finalized, it could open a clearer path for institutional money into assets like Bitcoin and Ethereum, but only where custodians and strict safeguards are in place.
3. The rules are not yet in force; a 60 day comment period and potential revisions mean the impact depends on how the final framework treats different custody models and coins.

Deep Dive

1. What The SEC Has Proposed

On 1 October 2026, the SEC published proposed Adviser and Regulated Fund Custody Rules; Crypto Custody Rules, updating custody standards under the Investment Advisers Act of 1940 and Investment Company Act of 1940 for crypto assets held by registered advisers and funds. The framework would let advisers self custody client crypto only when they determine no permitted custodian exists for a given asset and reaffirm that finding quarterly, with two person key approvals and segregated blockchain addresses per client. It would also let state chartered trust companies act as crypto custodians if they meet governance, segregation, audit and safeguarding conditions, expanding options beyond traditional banks and broker dealers as described in the SEC focused summary of the crypto custody rules.

2. Why It Matters For Crypto Markets

The proposal is designed to replace a long running grey area where advisers knew they had to use qualified custodians but could not tell which crypto arrangements truly qualified. By clarifying that certain self custody setups and vetted state trust companies can be acceptable, it aims to make it easier for regulated funds and registered investment advisers to offer direct crypto exposure rather than only ETFs or structured products, as highlighted in coverage of the new custody rule for advisers. In practice, custodians already support large caps like Bitcoin (BTC) and Ethereum (ETH), so those assets are most likely to benefit first, while smaller or newer tokens may remain constrained by custody and security requirements.

3. What Happens Next And Key Uncertainties

This is only a proposal; the SEC will take public comments for 60 days after Federal Register publication, and the final rule could tighten or loosen self custody permissions, auditor requirements or trust company conditions. Commissioners have already flagged risks, including conflicts of interest when advisers hold keys and uneven state level oversight of trust companies, so investor protection concerns may drive revisions. Open questions include how multisig or MPC wallets are treated, how far custodians will go beyond BTC and ETH, and whether compliance costs make self custody uneconomic for most firms.

Conclusion

The SECs crypto custody proposal is a major step toward giving investment advisers and regulated funds a workable, compliant path to hold digital assets, but nothing changes until a final rule is adopted. The real impact for crypto will depend on the final safeguards, which coins custodians support, and how quickly advisers embrace the new framework as a way to expand client exposure to the asset class.
