New SEC crypto rules threaten small advisers, but big firms win

The Securities and Exchange Commission’s proposed alternative for cryptocurrency custody could expand investment options while simultaneously making them simpler for larger advisory firms to provide.

According to the agency’s economic analysis, the expenses associated with safeguarding assets and arranging independent oversight may prompt smaller firms to forgo offering the service entirely.

Approved on October 1, the proposal permits advisers to hold covered client crypto assets when an eligible custodian is unavailable, provided certain safeguards are met. Table 8 models specific annual costs of $433,833 per adviser utilizing this option.

That financial estimate incorporates an independent control report but leaves out certain potentially substantial technology costs.

Consequently, an asset might become accessible through an adviser with ample custody resources while remaining entirely absent from another adviser’s platform.

SEC Commissioner Hester Peirce differentiated adviser “self-custody” from investors holding their own assets. In this scenario, an intermediary retains clients’ key materials, potentially including a non-controlling portion, meaning clients continue to rely upon that intermediary’s protective measures.

For ordinary advisory clients, the proposed amendments focus on crypto assets structured as funds or securities, whereas the appropriate scope for regulated-fund accounts is restricted to securities or comparable investments.

What the annual estimate includes

The most substantial modeled annual component is the independent internal control report, which the SEC estimates will cost an average of $376,000, alongside $57,833 allocated for recurring internal compliance labor.

Table 8 combines these figures while separately outlining an initial internal compliance cost of $173,499, with all values presented in 2026 dollars.

The internal projection accounts for 300 initial hours and 100 recurring annual hours calculated at a rate of $578.33 per hour. It encompasses information, communications, and formal agreements between the adviser and client to classify the asset as a financial asset under relevant state law.

This subtotal omits various technology, software, hardware, and associated systems and operational processes. The SEC anticipates these expenses will be economically significant. Because recordkeeping and disclosure burdens are detailed separately in other tables, this subtotal cannot function as an all-inclusive operating budget.

The accountant fee figure is derived from an inflation-adjusted previous estimate within the Paperwork Reduction Act analysis, rounded to the nearest $1,000 to align with the agency’s historical cost model. Report expenses may fluctuate depending on the specific assets, safeguarding systems, and specialized expertise required to evaluate different blockchain networks.

For this burden calculation, the agency presumes that roughly 823 advisers—representing 5% of the 16,442 total registered advisers—will utilize self-custody, though it cautions that actual adoption rates could prove lower.

Scale changes the cost of access

The economic analysis explicitly foresees that smaller advisory firms might choose against self-custody, whereas larger firms are more likely to possess the necessary resources to satisfy the required safeguards. It also points out opportunities to distribute certain expenses across a broader client base, multiple assets, or affiliated enterprises.

This dynamic establishes a distinct advantage without mandating a universal minimum firm size. An adviser managing substantial overall assets might maintain only a modest pool of covered crypto assets requiring this specific fallback mechanism.

Conversely, a firm with a dedicated crypto business model may already possess the precise expertise and infrastructure that another firm would be forced to acquire from scratch.

If the operational burden remains static, shared costs weigh much heavier on a limited pool of assets than on a larger one. Rather than charging only the clients utilizing the fallback, firms might choose to distribute these expenses across their wider business operations.

The SEC projects that numerous direct costs could ultimately be passed along to clients via fees or expenses. Managing greater volumes of assets and multiple networks can demand increasingly complex controls and specialized accountant oversight, thereby driving up absolute expenditures. The primary financial benefit stems from the ability to distribute or reuse existing infrastructure components.

Accountant pricing could fluctuate in either direction; the SEC warns that high demand for professionals capable of auditing crypto controls might make these services scarce and expensive, particularly for smaller advisers lacking substantial bargaining power.

An option that can expire for each asset

The proposed fallback relies entirely on the adviser establishing a written, reasonable basis—following due inquiry—that no qualified custodian is willing or able to maintain a given asset.

Advisers would be required to make this determination prior to taking custody and must reassess it at least quarterly thereafter. Custodian fees cannot serve as a valid basis for this determination.

An adviser is prohibited from selecting the self-custody fallback simply because a traditional custody arrangement appears more expensive. The definitive hurdle is the actual market availability of an eligible custodian for that specific asset, evaluated under the proposed criteria.

Should an adviser discover that a qualified custodian has become accessible, it must transfer the asset to that custodian as rapidly as reasonably practicable. This obligation can materialize between regularly scheduled quarterly reviews, and the proposal outlines no singular transfer deadline covering every scenario.

A firm might expend resources to support a particular asset only to be forced to relocate it out of adviser custody later. Furthermore, shifting eligibility rules could leave a firm managing only a narrow collection of unsupported assets over which it must distribute remaining administrative expenses.

If no client crypto assets remain in self-custody by the submission deadline of the report, the report itself will not be required. This could mitigate expenses for short-lived arrangements, though advisers retaining other covered crypto assets in self-custody will continue to face the corresponding obligations.

The safeguards buy independent scrutiny

This financial outlay coincides with a fundamental shift in asset custody. An adviser rendering investment advice would simultaneously retain client key materials, introducing distinct risks of misuse, misappropriation, and operational mistakes. Any lower-cost arrangement would need to be evaluated directly against these hazards.

As outlined in statements by SEC Commissioner Mark Uyeda, the proposed conditions mandate safeguarding expertise, robust cybersecurity protocols, routine annual reviews, formal reporting, and clear client disclosures.

Advisers would need asset-specific technical proficiency in key management systems, authorization protocols requiring two or more designated individuals, and strict segregation of every client’s assets.

The inaugural independent control report would become due within six months of assuming self-custody and at least once per calendar year moving forward. This evaluation would test the design, implementation, and overall effectiveness of internal controls while verifying reconciliations against the respective crypto network.

This framework introduces a level of oversight that goes far beyond an adviser’s internal self-assessment of its capabilities.

Quarterly client reporting would also be enforced, featuring electronic delivery options and exemptions for qualifying audited pools and regulated funds. Providing clients with visibility into balances and transactions supplements the mandated safeguards, while the accountant’s independent work addresses critical questions that raw account balances alone cannot resolve.

These safeguards will not eradicate custodial risk, and the SEC cautions that financial spending alone does not prove a firm’s safeguarding competence. A firm’s financial capacity to absorb compliance costs remains entirely separate from whether its internal systems effectively protect client assets.

Alternatives could soften the scale advantage

A statement issued on September 30, 2025, by SEC Commissioner Hester Peirce outlined conditional staff no-action relief designated for specific state trust companies, while also designating national and state banks as approved alternative custodians.

The October proposal would likewise allow eligible state trust companies to custody crypto assets, subject to thorough initial and ongoing annual due diligence regarding their authorizations and security safeguards. Where an approved institution supports a specific asset, clients might gain exposure without requiring their adviser to construct the proposed self-custody fallback architecture.

The resulting financial advantage will vary depending heavily on the individual asset and custody setup, given that a firm authorized to offer crypto custody does not automatically support every asset a client wishes to hold.

Ultimately, the core question for investors is whether the rule proposal will generate practical access at a reasonable cost alongside adequate protection levels. The SEC’s analysis indicates a clear prospective advantage for advisory firms possessing ample resources and scalable, reusable infrastructure.

The extent to which everyday clients benefit will ultimately hinge on actual corporate implementation expenses, the pricing models of independent accountants, and the specific assets that eligible custodians choose to support.
