What Is Rule 15a-6 and How Does Chaperoning Work for Non-US Brokers?

Navigating U.S. Markets Without a U.S. License

Cross-border capital has always been a balancing act: the opportunity to access U.S. investors weighed against one of the most demanding regulatory environments in the world.

For non-U.S. broker-dealers, that tension crystallizes in a single question: How can you market to U.S. institutional investors without registering as a U.S. broker-dealer?

The answer lives in Rule 15a-6, a framework the SEC introduced in 1989. It created a set of conditional exemptions, the most important of which is chaperoning. Chaperoning allows international firms to access U.S. deal flow through a U.S.-registered broker-dealer, with the regulatory protections U.S. law requires.

Rule 15a-6 at a Glance

At its core, Rule 15a-6 recognizes that global capital can’t stop at the U.S. border. It permits non-U.S. broker-dealers to interact with certain classes of U.S. investors without SEC registration, provided strict conditions are met.

The rule defines four primary pathways:

1. Unsolicited trades – servicing U.S. investors who reach out to you.
   
   
2. Research distribution – sharing research with large institutional investors (MUSIIs).
   
   
3. Chaperoned solicitation – engaging U.S. institutions through a U.S. broker-dealer.
   
   
4. Limited transactions – with specific categories like international organizations or foreign persons temporarily in the U.S.
   
   

The most commercially relevant path is chaperoning under 15a-6(a)(3).

How Chaperoning Works

Think of chaperoning as a joint venture in compliance.

The non-U.S. broker-dealer originates the relationship.
The U.S. broker-dealer executes the trade and assumes defined regulatory duties:

• Issuing confirmations and statements

• Safeguarding funds and securities

• Maintaining books and records

• Meeting SEC net capital and custody requirements

For U.S. institutional investors below the "major" threshold (under $100M AUM), a U.S.-registered representative must be present on every call. The arrangement only works when the U.S. partner is truly embedded in the workflow.

Why It Matters Now

Global allocators are shifting capital into alternatives, across borders and asset classes, at a pace that creates real opportunity for non-U.S. deal professionals. The regulatory framework for accessing U.S. institutional investors compliantly exists, and firms that use it correctly are active in U.S. markets today.

The SEC has brought enforcement actions against foreign firms for soliciting U.S. investors outside 15a-6 boundaries. In 2019, the SEC charged Outset Global LLP, a UK-based firm, for soliciting at least 35 U.S. institutional investors and executing thousands of transactions without a chaperoning agreement in place, resulting in disgorgement and civil penalties. (SEC Release No. 34-87158) For international firms, a credible chaperoning arrangement is the foundation for compliant access to U.S. deal flow. 

The Finalis Perspective

Chaperoning is as much an infrastructure challenge as a legal one. Fragmented relationships and manual oversight slow execution, increase costs, and leave firms exposed when regulations tighten.

The Finalis platform is built around that operational reality.
It integrates:

• Compliance automation: onboarding, recordkeeping, audit trails

• Cross-border execution: trade flow between U.S. and non-U.S. teams in one environment

• Network access: direct connectivity to institutional allocators and issuers across the Finalis member network

For non-U.S. broker-dealers, that translates to faster time-to-market, lower operational risk, and direct entry into U.S. private capital.

Frequently Asked Questions

What is SEC Rule 15a-6?
SEC Rule 15a-6 provides a conditional exemption that allows foreign broker-dealers to conduct certain securities activities with U.S. persons without registering with the SEC. The exemption has several tiers, with the most commonly used requiring a U.S. registered broker-dealer to act as a chaperone. The rule was adopted to facilitate cross-border securities transactions while maintaining U.S. investor protections.

Who does Rule 15a-6 apply to?
Rule 15a-6 applies to foreign broker-dealers, meaning firms that conduct securities business outside the United States and are not registered with the SEC. It also applies to U.S.-registered broker-dealers that agree to act as chaperones for those foreign firms. Foreign firms seeking to engage with U.S. institutional investors commonly rely on 15a-6 rather than pursuing full SEC and FINRA registration.

What is an “institutional investor” under Rule 15a-6?
Under Rule 15a-6, “institutional investor” is defined broadly and includes registered investment companies, banks, savings and loan associations, insurance companies, investment advisers registered with the SEC, government entities, and certain other sophisticated investors. According to SEC guidance, the institutional investor definition is designed to limit the exemption to transactions with parties presumed to have the sophistication to evaluate the risks involved.

How does chaperoning work under Rule 15a-6?
Under the chaperoning model, a U.S.-registered broker-dealer (the chaperone) supervises communications between the foreign broker-dealer and U.S. institutional investors. The chaperone reviews and approves research, attends meetings, effects securities transactions, and maintains required books and records. The chaperone takes on regulatory responsibility for the supervised activities, which is why selecting an experienced chaperone matters.

What is the difference between Rule 15a-6 chaperoning and full FINRA registration? Full FINRA registration means the foreign firm registers as a U.S. broker-dealer, hires a CCO, meets net capital requirements, and submits to the full range of SEC and FINRA rules. Rule 15a-6 chaperoning is a narrower path: the foreign firm does not register, but its U.S. activities are supervised by the chaperone broker-dealer. Chaperoning is appropriate when a foreign firm’s U.S. activity is limited primarily to institutional investors; full registration is required for broader retail activity.

What does the chaperone broker-dealer actually do?
The chaperone broker-dealer performs several functions: it reviews research and communications before distribution to U.S. investors, effects trades on behalf of U.S. investors who respond to the foreign firm’s recommendations, maintains records required under U.S. securities law, and assumes supervisory responsibility for the supervised activities. According to FINRA, the chaperone’s supervisory obligations are meaningful and require active involvement.

Can a foreign firm engage retail U.S. investors under Rule 15a-6?
No. Rule 15a-6 does not permit foreign broker-dealers to engage U.S. retail investors without full SEC and FINRA registration. The exemption is specifically limited to transactions with institutional investors as defined under the rule. Foreign firms seeking to work with U.S. retail clients must register as a U.S. broker-dealer or affiliate with one.

What triggers the need for a 15a-6 chaperone arrangement?
A foreign broker-dealer needs a 15a-6 chaperone arrangement when it wants to solicit U.S. institutional investors, distribute research to U.S. investors, or effect securities transactions involving U.S. persons, without registering as a U.S. broker-dealer. Cross-border M&A advisory, capital raising from U.S. institutions, and international equity research distribution are common scenarios.
