The U.S. Securities and Exchange Commission proposed on October 1 a 760-page rule that would let registered investment advisers and funds hold clients' crypto assets themselves when no approved custodian exists. The proposal covers registered investment advisers, registered funds such as mutual funds and ETFs, and business development companies (BDCs), and it arrives two weeks after the Clarity Act — Congress's flagship crypto market bill — fell short in the Senate on September 15, receiving 49 votes where 60 were needed.

SEC Chairman Paul Atkins framed the move in sweeping terms. "With our new proposal, the SEC is taking the most historic step yet to modernize federal securities regulations for crypto assets," Atkins said, adding that the U.S. "must and will lead" as the "Crypto Capital of the World."

What are the two new custody paths?

The proposal opens two routes for advisers and funds that until now had to place client assets with a "qualified custodian," typically a bank or regulated broker.

• Path 1: State trust companies. A trust company chartered by a state banking regulator can serve as custodian, generally available subject to conditions: an annual check of state authorization, review of audited financials and internal controls, and full segregation of client assets.
• Path 2: Adviser or fund custody. The adviser or fund itself holds the keys — but only when no permitted custodian is available, a condition it must verify every quarter. Safeguards include two-person approval for transactions, a separate crypto address for each client, yearly cybersecurity reviews, independent accountant reports, and quarterly client statements.

The rule also relocates the main adviser custody provision from Rule 206(4)-2 to a new Rule 223-1, and permits firms to keep certain records directly on crypto networks, provided they can produce them in human-readable form.

"For too many assets a qualified third-party custodian simply does not exist yet," Atkins said, acknowledging the gap that kept most advisers away from direct crypto holdings or pushed clients toward Bitcoin ETFs.

Is this really "self-custody"?

No, and Commissioner Hester Peirce made the distinction explicit, placing "self-custody" in quotation marks in her statement on the proposal. In crypto parlance, self-custody means an individual holding keys in, say, a hardware wallet. The rule instead describes adviser custody: the firm becomes the vault, and clients' asset security depends on how well that firm manages keys. Peirce, a long-standing advocate for individuals' right to hold their own crypto, noted the rule does not change that right either way.

Why the operational safeguards?

The conditions read as a response to 2026's incidents. Exchange Bitget lost roughly $350 million in a hack and turned to a protection fund that is effectively a Bitcoin bet. Earlier, the Coldcard hardware wallet breach drained $114 million in Bitcoin and dented confidence in hardware custody.

Two-person approval means one rogue employee or one stolen laptop cannot move funds alone. Separate per-client addresses prevent commingling of assets. Still, rules cannot make a small advisory firm as hard to attack as a specialist custodian; independent accountant reports and cybersecurity reviews may cost enough that smaller advisers skip crypto entirely and stay with ETFs.

What is the proposal's biggest weakness?

The commission itself. Peirce departed October 2, leaving Chairman Atkins and Commissioner Mark Uyeda — both Republicans — with three empty seats. SEC rules let sitting commissioners constitute a quorum, so the agency can act, but the custody rule could be finalized with no dissent on the record and no Democratic input.

Agency rules are easier to change than statutes. The SEC's own 2023 custody proposal, which would have tightened crypto custody, was withdrawn after heavy industry pushback. A future commission with a different majority could reopen this rule through its own rulemaking. The Clarity Act's Senate failure — driven by disputes over ethics provisions, stablecoin safeguards, and tax treatment — means no statutory backstop is coming soon.

The proposal now enters the public comment process, and its fate — along with the durability of any final rule — will hinge on both the comment period and whether the Senate's vacant commission seats are filled before adoption.
