The SEC crypto custody proposal released on Oct. 1, 2026 would give registered investment advisers and regulated funds a defined way to hold crypto assets. That includes a tightly conditioned route to self-custody and the option of using state trust companies. It’s still a draft, though. NewsBTC stressed in its analysis that the changes have not been finalised. Public comments are due on Dec. 7, 2026.
- The SEC’s official press release says the framework covers registered investment advisers, registered investment companies and business development companies.
- Advisers and funds could hold private keys themselves only after determining, at the start and every quarter after, that no qualified custodian is available.
- State trust companies could act as custodians for the crypto assets of clients and regulated funds.
- The Advisers Act custody rule would be renumbered from Rule 206(4)-2 to Rule 223-1.
- The package also reaches beyond crypto, updating adviser audit rules and broker-dealer custody of fund assets.
Timeline of the SEC crypto custody proposal
- 2023: A Gensler-era SEC custody proposal draws criticism. Critics said it would have shut advisers out of crypto, and it was later withdrawn.
- September 2026: The Clarity Act, a crypto market structure bill, fails to pass the Senate.
- Oct. 1, 2026: The SEC proposes new custody rules and amendments in Press Release 2026-100.
- Oct. 6, 2026: The proposal is published in the Federal Register as Release Nos. IA-7023 and IC-36353 (File No. S7-2026-35).
- Dec. 7, 2026: The public comment period closes.
Why custody rules matter for advisers
As NewsBTC’s analysis puts it, the hard part of institutional crypto is often not whether a firm can technically hold a private key. The harder question is how an adviser proves control, segregation and responsibility to clients and regulators. SEC Chairman Paul Atkins has framed the proposal as replacing uncertainty caused by custody rules “crafted for a bygone era.”
The political backdrop matters as well. Quartz reported that the proposal follows the Clarity Act’s failure to pass the Senate in September. After that, according to the outlet, regulators turned to their existing authority to address specific parts of the market. Quartz places the custody plan in that context.
How the self-custody route would work
According to a Legal 500 summary, self-custody comes with a long list of conditions. Firms would need safeguarding expertise and private key management controls. They would also need joint authorization, cybersecurity measures, internal control reports, quarterly account statements and a UCC financial asset election.
Goodwin notes that an adviser would be treated as having custody if it, or a related person, holds any part of the keys needed to access and transact in an asset. Sullivan & Cromwell adds that the self-custody requirements would also cover certain non-security crypto assets held for regulated funds, including Bitcoin, Ether and Solana. For regulated funds, self-custody would come with board oversight requirements.
Changes beyond digital assets
The Legal 500 summary also lists broader changes. The proposal would drop the requirement that Custody Rule accountants be registered with and inspected by the PCAOB. It would also add an exception for discretionary trading authority, extend audit deadlines for funds of funds and simplify broker-dealer custody of fund assets under Rule 17f-1.
What officials said and how markets moved
Atkins said the plan would give advisers and funds a clear framework and “a compliant pathway where none existed before,” CoinDesk reported. According to the outlet, the document runs to 760 pages.
Commissioner Hester Peirce offered an important clarification, per Yahoo Finance. “Self-custody” here means the adviser acting as custodian, not individuals holding their own keys. That is a different setup from what retail users typically mean by the term, such as running a browser wallet like the MetaMask extension. The same report notes that the proposal reverses the 2023 approach, which a16z had called “illegal, infeasible, and dangerous” before it was withdrawn.
The available market data doesn’t link recent price moves to the custody news. Major coins drifted lower over the past week. The Crypto Fear & Greed Index stood at 51 (Neutral) on Oct. 29, 2026.
| Asset | Price (USD) | 24h change | 7d change |

| Ether (ETH) | $2,314.60 | -1.56% | -6.35% |
| Solana (SOL) | $99.97 | -1.49% | -6.77% |
Prices per CoinGecko as of Oct. 29, 2026, 02:05 UTC.
What to watch next
The next milestones are comment letters, any revisions and a final rulemaking timetable. After that comes the practical test: how custodians and advisers turn the text into written policies, customer disclosures, testing and ongoing reporting. Those procedures often matter more than the date on the announcement.
Risks remain. The details and final scope could change after public feedback. Firms choosing self-custody would take on key-management and cyber risk directly. Regulated access also doesn’t protect investors from price swings: Bitcoin was down 28.88% over the year to Oct. 29, according to CoinGecko data. Rules differ by jurisdiction, so firms should check with qualified counsel. Nothing here is investment or legal advice.
