Briefing
The SEC’s Division of Investment Management issued a No-Action Letter on September 30, 2025, providing critical regulatory clarity by permitting Registered Investment Advisers (RIAs) and Registered Funds to treat qualifying state-chartered trust companies (STCs) as “banks” for the custody of crypto assets. This action immediately resolves a major legal ambiguity under the Investment Advisers Act of 1940 and the Investment Company Act of 1940, allowing institutional capital to engage with the digital asset market via a regulated custody path. The relief is explicitly conditioned on the RIA or Fund conducting initial and annual due diligence and maintaining a written custody agreement that mandates asset segregation and prohibits rehypothecation.

Context
Before this guidance, the primary compliance challenge for RIAs and Registered Funds was the strict “qualified custodian” requirement, which largely limited crypto custody to federal banks or specifically approved entities, creating a significant bottleneck for institutional adoption. The statutory definition of “bank” under the 1940 Acts was subject to debate regarding state-chartered trust companies (STCs) that did not accept deposits, leaving a substantial portion of the crypto custody market operating under a cloud of potential enforcement action. This regulatory uncertainty forced many institutional players to either avoid digital assets or utilize complex, non-standard legal structures.

Analysis
This No-Action Letter fundamentally alters the operational compliance framework for asset managers seeking digital asset exposure. The immediate effect is the expansion of the “qualified custodian” pool, directly increasing competition and capacity within the institutional custody market. Regulated entities must now integrate a new due diligence module into their compliance systems to perform and document the required initial and annual assessment of the State Trust Company’s operational controls, including cybersecurity and private key management.
The requirement for a best interest determination and explicit risk disclosure to clients elevates the fiduciary standard, shifting the burden of custodial risk mitigation onto the RIA. This ensures investor protection remains paramount despite the expanded options.

Parameters
- Regulatory Instrument ∞ No-Action Letter (NAL)
- Effective Date ∞ September 30, 2025
- Governing Rule ∞ Advisers Act Rule 206(4)-2
- Custody Requirement ∞ Annual Due Diligence and Oversight

Outlook
This NAL sets a significant precedent, signaling the SEC staff’s willingness to use targeted relief to modernize the custody framework ahead of formal rulemaking, which is still anticipated. The action may encourage state-chartered trust companies to further specialize in digital asset custody to meet the rigorous conditions, potentially leading to a fragmentation of custodial standards across state lines. The next phase will likely involve the SEC’s proposed amendments to the custody rule, which will formalize these standards and determine if the temporary relief will be codified into a permanent, industry-wide regulatory framework.

Verdict
The SEC’s targeted custody relief provides a crucial, operational on-ramp for institutional capital, cementing a dual-track regulatory approach for digital asset safekeeping.
