The U.S. Securities and Exchange Commission has proposed a new regulatory framework for how registered investment advisers and regulated funds can custody crypto assets. The proposal is notable because it would explicitly address situations in which traditional custodians are unavailable and could permit limited self-custody under defined conditions.
Direct summary: The SEC is not creating a general right for investors or financial firms to self-custody crypto without restrictions. The proposal is aimed at registered investment advisers and regulated funds, and it would introduce specific conditions, controls, recordkeeping and disclosure requirements. It is still a proposal and has not yet become a final rule.
What happened
On October 1, 2026, the SEC proposed new rules and amendments under the Investment Advisers Act of 1940 and the Investment Company Act of 1940 covering custody of crypto assets by registered investment advisers and regulated funds.
According to the SEC, the proposal is intended to modernize custody rules that were largely written before crypto assets became a significant part of financial markets. The Commission said the existing framework can make it difficult for advisers and funds to determine how digital assets may be held in a compliant way.
The proposal would introduce several important changes.
First, it would allow registered investment advisers and regulated funds to use self-custody for certain crypto assets in limited circumstances and subject to conditions. Commissioner Hester Peirce explained that one threshold condition would be a determination that no permitted custodian is available to maintain the relevant crypto asset. That determination would need to be made before self-custody and revisited on a quarterly basis.
Second, the proposal would allow state trust companies to serve as custodians for client and regulated-fund crypto assets when the applicable conditions are satisfied.
Third, the SEC would update related recordkeeping, disclosure and reporting requirements. The proposal also includes changes affecting audits and broker-dealer custodial services.
The SEC has opened the proposal for public comment. The comment period is scheduled to remain open for 60 days after publication in the Federal Register.
Why it matters
Crypto custody has long been one of the most difficult areas for traditional financial firms entering digital-asset markets.
Holding crypto is technically different from holding conventional securities. Control over a private key can effectively determine control over an asset, and losing access to that key can make recovery impossible. At the same time, many existing financial rules were designed around banks, broker-dealers, physical certificates and traditional account-based infrastructure.
That creates a practical conflict. Financial firms are expected to safeguard client assets under established custody rules, but some crypto assets may not be supported by the custodians those rules were originally designed around.
The new SEC proposal attempts to bridge that gap rather than treating crypto custody as if it were identical to traditional securities custody.
The self-custody element is especially significant. It recognizes that there can be situations in which a regulated firm needs to hold cryptographic keys directly because an eligible third-party custodian is not available. But the proposal also acknowledges that direct control creates additional operational and conflict-of-interest risks.
For the broader crypto industry, clearer custody rules could make it easier for regulated advisers and funds to offer exposure to a wider range of digital assets. It could also increase demand for institutional-grade wallet infrastructure, key-management systems, audits, internal controls and custody technology.
What crypto users should know
The proposal does not directly regulate how an ordinary individual stores Bitcoin, Ethereum or other crypto in a personal non-custodial wallet.
A user who controls their own seed phrase or private keys is operating in a very different context from a registered investment adviser holding assets for clients.
The SEC proposal is primarily about professional fiduciaries and regulated investment vehicles. Its importance for ordinary users is indirect: it may influence which crypto assets financial institutions are willing to support, how institutional custody products are designed, and how regulators distinguish between third-party custody and direct key control.
It also reinforces a fundamental distinction in crypto.
For a deeper explanation, see Custodial vs. non-custodial wallets and our guide to what a crypto wallet actually stores.
With a custodial service, another organization controls or safeguards the keys on behalf of the user. With a non-custodial wallet, the user controls the keys directly. In both cases, the blockchain records the assets; the wallet or custodian manages the credentials required to authorize transactions.
For institutions, however, controlling those credentials involves more than simply keeping a seed phrase safe. A regulated firm may need multi-person authorization, hardware security modules, geographically separated backups, documented recovery procedures, segregation of duties, audit trails and policies governing who can approve transactions.
That is why institutional self-custody can look very different from self-custody by an individual.
Potential impact on wallets and custody infrastructure
If the SEC ultimately adopts a framework similar to the proposal, custody technology could become an even more important part of institutional crypto infrastructure.
Wallet providers serving professional clients may face growing demand for features such as policy-based transaction approvals, role separation, multi-signature or multi-party computation systems, detailed transaction logs, key recovery procedures and integration with compliance systems.
The proposal may also encourage financial firms to evaluate the difference between outsourcing custody and operating their own key-management infrastructure.
For consumer wallet users, there is no immediate technical change. Existing seed phrases, private keys and blockchain addresses continue to work as before. The proposal does not alter Bitcoin or Ethereum protocol rules and does not change who controls assets in a normal self-custodial wallet.
What happens next
The proposal must still go through the SEC rulemaking process.
Public comments can lead to revisions, and the final rules could differ materially from the current proposal. Until a final rule is adopted and becomes effective, firms should not treat the proposal as a completed change in U.S. securities regulation.
For that reason, the most important point today is not that institutional crypto self-custody has suddenly become unrestricted. It has not.
The important development is that the SEC is proposing a dedicated framework that explicitly recognizes the technical realities of crypto custody and attempts to define circumstances in which regulated advisers and funds may hold crypto assets directly.
For the crypto industry, that moves the custody debate away from a simple question of whether self-custody can fit within traditional rules and toward a more practical question: what controls are required when regulated institutions manage private keys themselves?
