SEC Digital Asset Funds and Custody Regime is a U.S. federal profile for how the Investment Company Act of 1940, the Investment Advisers Act of 1940, and related SEC custody rules apply to digital-asset investment activity. The operative baseline is in force, but there is no single enacted “digital asset funds” statute. As of June 4, 2026, the framework combines existing fund custody requirements, the Advisers Act custody rule, SEC staff positions on crypto-related fund products, and a 2025 no-action letter addressing state trust company custody of crypto assets.
Investment Company Act and Advisers Act Custody Baseline
For SEC-registered investment advisers, Rule 206(4)-2 under the Advisers Act governs custody of client funds and securities. The rule generally requires those assets to be maintained by a qualified custodian in a client-named account or an account containing only the adviser’s clients’ assets. It also includes client notice, account-statement, independent verification, pooled-vehicle audit, and qualified-custodian provisions.
For regulated funds, the Investment Company Act framework is centered on Section 17(f), Section 26(a), and related rules. SEC staff summarized that registered funds generally must place and maintain securities and similar investments with specified custodians. Rule 17f-1 addresses custody of securities and similar investments with members of national securities exchanges, including segregation, limits on liens, accountant examination, and SEC inspection access.
Crypto Asset Custody and State Trust Companies
The main crypto-specific development is the SEC Division of Investment Management no-action letter issued on Sept. 30, 2025. The letter states that staff would not recommend enforcement action against registered advisers or regulated funds that treat a qualifying state trust company as a “bank” for custody of crypto assets and related cash or cash equivalents, subject to representations and conditions. The letter defines crypto assets as digital representations of value recorded on a cryptographically secured distributed ledger.
The no-action position is conditional. Before engaging a state trust company, and annually, a registered adviser or regulated fund must have a reasonable basis after due inquiry to believe the company is state-authorized and maintains safeguards addressing risks such as theft, loss, private key management, and cybersecurity. The arrangement also must include a written custody agreement, limits on lending or rehypothecation without consent, segregation from the trust company’s assets, risk disclosure, and a best-interest determination. The letter states that it is a staff position only, not a Commission rule.
Digital Asset Fund Issues: Valuation, Liquidity, and Product Structure
SEC staff has historically treated crypto-related registered fund products as raising issues beyond custody. The 2018 cryptocurrency holdings letter identified valuation, liquidity, custody, ETF arbitrage mechanisms, and potential manipulation or other market risks as areas implicated by registered funds investing in digital assets or cryptocurrency-related investments. A later 2021 Bitcoin futures staff statement discussed cash-settled Bitcoin futures as avoiding some direct crypto custody challenges, but that statement was withdrawn on May 6, 2025.
These materials do not create a standalone approval pathway for crypto funds. They are better read as interpretive and supervisory context layered on top of existing Investment Company Act, Advisers Act, disclosure, valuation, liquidity, derivatives, custody, and anti-fraud requirements. Spot crypto exchange-traded products organized outside the 1940 Act may raise different issues and should not be conflated with registered investment companies.
Status and Rulemaking Timeline
The SEC’s 2023 Safeguarding Advisory Client Assets proposal would have redesigned the Advisers Act custody rule and expanded it from “funds and securities” to broader “assets,” including crypto assets. The Commission withdrew that proposed rulemaking, stating that it did not intend to issue final rules for the withdrawn proposals; the withdrawal took effect June 17, 2025.
A separate Spring 2025 Unified Agenda item, RIN 3235-AN46, lists “Amendments to the Custody Rules” as a proposed-rule-stage item. The agenda describes potential amendments or new rules under both the Investment Advisers Act and Investment Company Act to modernize custody of advisory client and fund assets, including crypto assets. The agenda is not itself a rule and does not impose obligations.
Jurisdictional Impact
This is a U.S. federal securities-law profile. It is most relevant to registered investment advisers, private fund advisers with custody issues, registered investment companies, business development companies, fund boards, fund service providers, and custodians serving crypto asset strategies. It does not cover state money-transmitter licensing, CFTC commodity-pool rules, or tax treatment.
