One of institutional crypto's biggest unresolved questions is deceptively simple: who is allowed to hold the assets?
The U.S. Securities and Exchange Commission is moving closer to rewriting that framework. A proposed rule covering crypto custody by investment advisers and investment companies has been sent to the White House Office of Information and Regulatory Affairs for review.
The proposal is not law, but its final direction could reshape institutional crypto infrastructure.
Why crypto custody is difficult
Investment advisers have legal duties to safeguard client assets. Conventional securities have mature custody infrastructure; crypto raises harder questions:
- Is an exchange an acceptable custodian?
- Can advisers self-custody?
- How should staking assets be treated?
- What happens if a custodian fails?
- Who controls private keys?
- How should tokenized securities be held?
The answers determine which firms can serve institutional clients.
What the SEC may be trying to clarify
The SEC says the rulemaking is intended to clarify how advisers and investment companies can custody crypto assets while modernizing outdated custody provisions.
That language suggests an effort to build a workable framework around existing institutional activity. Large investors typically require regulated custody, asset segregation, auditability, insurance and operational controls. Clearer rules could reduce uncertainty for advisers, funds, asset managers and tokenized-security platforms.
Who could benefit?
The outcome could strengthen firms already building regulated custody businesses, including Coinbase, Anchorage Digital, specialist custodians and traditional banks.
The decisive issue is how the final rule defines a permitted or qualified custodian. Strict requirements could concentrate the market among a small set of heavily regulated providers. More flexible rules could broaden competition.
Why custody matters for tokenization
This debate is no longer only about Bitcoin. Stocks, Treasuries, funds and private assets increasingly use blockchain infrastructure.
If securities move onchain but regulated institutions cannot legally or safely hold them, adoption stalls. Custody is therefore a foundational layer of the tokenization stack:
tokenized asset → custody → trading → collateral → settlement.
Every later step depends on legally recognized control of the asset.
A review is not a final rule
The current development should not be overstated. White House review does not mean the rule has been adopted. The process may still include agency publication, public comment, revisions and a final vote. Material details can change.
Balancing innovation and investor protection
Flexible rules could accelerate adoption, but custody failures remain one of crypto's central risks. Exchange collapses and hacks have repeatedly shown why segregation and operational controls matter.
Regulators face a genuine trade-off. Rules that are too restrictive can freeze innovation; rules that are too loose can expose investors to theft, misuse and counterparty failure.
What to watch next
Key developments include publication of the proposal, the definition of qualified custodian, treatment of staking and self-custody, rules for tokenized securities, bank participation and public comments from crypto and traditional custodians.
Crypto markets often focus on prices and ETFs. Custody is more fundamental. Without reliable, legally recognized custody, institutional digital-asset markets cannot scale.
Frequently asked questions
Are the new SEC crypto custody rules final?
No. The proposal remains in the regulatory review process.
Why do investment advisers need custody rules?
Advisers must safeguard client assets and reduce the risk of theft, misuse or loss.
Could the rule help crypto custodians?
Potentially, but the impact depends on the final definition of permitted or qualified custodians.
