SEC advances crypto custody rules for funds

TLDR

The SEC has proposed new crypto custody rules for investment advisers and regulated funds that could make it easier for them to hold digital assets for clients.

1. The proposal creates a dedicated crypto custody framework, including limited self-custody and the use of state trust companies as qualified custodians.
2. If finalized, it could unlock a large pool of professionally managed capital for assets like Bitcoin (BTC) and Ethereum (ETH), but with strict security and audit conditions.
3. The rules are not yet in force; a 60 day comment period and potential revisions mean the final impact and timeline remain uncertain.

Deep Dive

1. What The SEC Has Proposed

On October 1, 2026, the SEC unveiled an extensive crypto custody framework for registered investment advisers and regulated funds, updating rules under the Investment Advisers Act and Investment Company Act to explicitly cover digital assets. The proposal, described as providing a compliant pathway where none existed before, outlines how advisers and funds may hold crypto, including the option of self-custody in narrowly defined circumstances and the ability to use state trust companies as custodians for client assets and fund holdings.

This is a proposal, not a final rule. Public comments will be accepted for 60 days after publication in the Federal Register, and the SEC can modify the framework before any final vote, as summarized in this SEC crypto custody explainer.

2. How It Could Change Fund Access To Crypto

Under the draft rules, advisers could self-custody client or fund crypto only when they can document that no permitted third party custodian is available for a given asset, and they must reassess that conclusion at least quarterly. Safeguards include multi-person authorization for key use, segregated blockchain addresses per client, and independent control reports on custody systems, while state trust companies could become qualified custodians if they meet written safeguarding, audit and segregation requirements.

Analysts note that registered investment advisers collectively oversee more than 100 trillion dollars in client assets, so even modest crypto allocations under this rule could be meaningful, as highlighted in this analysis of adviser fund flows into crypto.

3. Risks, Unknowns And What To Watch

Key regulators have flagged risks around advisers acting as their own custodians, potential conflicts of interest, and uneven safeguards at state chartered trust companies compared with federally regulated banks. Operationally, the hard part is proving not just onchain balances but legal ownership, exclusive key control and freedom from offchain encumbrances, all of which auditors must reconcile over time.

For crypto users, the main things to watch are: how industry comment letters challenge or support self-custody and trust company provisions, which custodians build compliant offerings first, and whether the final rule narrows or broadens the initial scope.

Conclusion

The SECs crypto custody proposal moves institutional access from a grey area to a potential rulebook, but the details still have to survive the comment and revision process. If core features such as conditional self-custody and expanded custodian eligibility survive, professionally managed funds could begin holding more spot crypto directly, with the earliest and deepest impact likely in large cap assets and on firms that can meet the new security and audit standards.
