Definition

Under the United States SEC investment-adviser custody rule, a qualified custodian is a specified type of regulated institution permitted to maintain client funds or securities.

The term belongs to a specific rule

Rule 206(4)-2 includes qualifying banks, registered broker-dealers, registered futures commission merchants and certain foreign financial institutions. The applicable category depends on the institution, assets held and conditions in the rule.

For example, the futures commission merchant category applies only to specified client funds, security futures and securities incidental to commodity futures or options transactions.

The label does not cover every asset automatically

A company providing wallet or safekeeping technology is not automatically a qualified custodian. Its regulatory status and the way it maintains the relevant assets must satisfy the applicable rule.

Other jurisdictions use different custody categories. A product should identify the jurisdiction and rule whenever it uses the phrase qualified custodian.

What it does not mean

A custodian is any entity that safeguards assets or related credentials. Qualified custodian is a regulatory classification under a particular legal framework, not a general synonym for a secure custodian.

Questions about qualified custodian

Is every crypto custodian a qualified custodian?

Can a foreign financial institution qualify?
The rule includes certain foreign financial institutions that customarily hold financial assets and segregate advisory client assets from proprietary assets.
Does using a qualified custodian remove custody risk?
No. Regulation and segregation provide safeguards, but operational, legal, cyber and counterparty risks can remain.
