The U.S. Securities and Exchange Commission proposed a crypto custody framework on October 1, 2026, allowing registered investment advisers, investment companies and business development companies to hold digital assets under defined conditions. Chairman Paul Atkins said the move replaces "the grey of uncertainty created by custody rules crafted for a bygone era."

What does the rule actually change?

The proposal creates a tailored regime for crypto assets held by advisers and funds, closing a gap the SEC has acknowledged for years. Under current rules, advisers face ambiguous compliance paths when clients want crypto exposure.

Self-custody is permitted only after an adviser documents that no qualified custodian is available for a specific token. Firms must reassess that judgment every quarter and migrate assets to a qualified custodian as soon as reasonably practicable once one emerges. Advisers choosing self-custody must also implement private key safeguards, cybersecurity controls, and strict segregation of client holdings.

State trust companies would gain a parallel path. To qualify, a trust company must hold state authorization for crypto custody, maintain audited financial statements and internal control reports, and keep client assets segregated from its own balance sheet.

Why is the SEC acting without a market structure bill?

Congress has not delivered the statutory framework the industry expected. The Clarity Act, which would have settled jurisdictional questions across digital assets, stalled in the Senate in September. The SEC is now exercising existing authority rule by rule.

Jeff Ko, chief analyst at blockchain infrastructure provider ViaBTC, framed the move as part of a broader pattern. "What we're increasingly seeing is the SEC using the authority it already has to solve individual bottlenecks one by one, issuance, tokenization, trading exemptions and now custody," he told CNBC. Ko added that expanding the eligible custodian pool could reduce both the cost and complexity of institutional digital asset investing, where a small group of providers has historically dominated.

What did SEC leadership say?

Atkins tied the proposal to the scale the market has reached. "The crypto asset market has grown from a niche curiosity into a multi-trillion-dollar asset class to which investors actively seek exposure," he said in a statement. "Unfortunately, our rules and regulations have not kept pace." He added that the proposal "would provide a clear regulatory framework for the custody of crypto assets, giving investment advisers and funds a compliant pathway where none existed before."

What happens during the comment period?

The proposal will be open for 60 days of public comment once it appears in the Federal Register, the standard window for industry feedback before any final adoption. The package also revises audit, recordkeeping and disclosure requirements tied to how advisers and funds handle crypto on behalf of clients.

The custody rule follows two earlier SEC actions this year: an Innovation Exemption for tokenized stock trading and the Regulation Crypto Assets framework issued in August. Together they form what the agency describes as a comprehensive digital asset program built without new legislation.

Broader market conditions give the rule added context. Bitcoin has rebounded more than 40% from its July low, a recovery from a downturn that stretched from late 2025 into the first half of 2026. That price recovery has coincided with renewed institutional appetite for digital assets, even as the structural custody constraints remain unresolved.

The 60-day Federal Register window is the next concrete deadline to watch.
