Agency Cross Transactions: Rule 206(3)-2 Consent and Disclosure

An agency cross transaction happens when an investment adviser, acting as broker, matches a buy order from one advisory client with a sell order from another and collects compensation from both sides. Section 206(3) of the Investment Advisers Act of 1940 prohibits these trades unless the adviser first discloses the dual role in writing and obtains the client’s consent. SEC Rule 206(3)-2 offers a narrower alternative that replaces trade-by-trade consent with prospective authorization, per-trade confirmations, and an annual summary — but only if every condition is met.

Why the Statute Restricts These Trades

Section 206(3) makes it unlawful for an adviser acting as broker for someone other than its advisory client to effect a securities trade for that client’s account without disclosing, in writing before the transaction, the capacity in which it is acting and obtaining consent.¹ The concern is direct. A firm that earns commissions from both the buyer and the seller has a financial incentive to complete the trade regardless of whether the price is optimal for either client. The statute separates the adviser’s fiduciary role from its brokerage profit motive by refusing to let the two blur without the client’s informed sign-off.

What Rule 206(3)-2 Requires

Rule 206(3)-2 lets an adviser skip the default requirement of per-trade written consent and instead operate under a single prospective authorization, provided the firm follows the rule’s framework in full.² It does not soften the underlying fiduciary duty. It substitutes a structured system of upfront disclosure, transaction-level confirmation, and yearly reporting for the trade-by-trade approval Section 206(3) would otherwise demand.

Who Can Rely on the Rule

The rule is available to an investment adviser, or to a person registered as a broker-dealer that controls, is controlled by, or is under common control with an investment adviser.² Practically, the firm executing the cross must have broker-dealer registration itself or through an affiliate. A standalone advisory firm with no broker-dealer arm cannot use the rule because it has no capacity to act as broker in the first place.

No Recommendation to Both Sides

The condition that trips up firms most often: the adviser cannot have recommended the same transaction to both the buyer and the seller. Rule 206(3)-2(a)(5) bars any agency cross transaction where the same adviser, or an adviser and a person it controls or is controlled by, recommended the trade to both sides.² If the firm told both clients to do the trade, the conflict is too severe for streamlined consent to cure. One side’s order has to have originated independently.

Written Consent Given in Advance

The client must sign a written consent prospectively authorizing the adviser to execute agency cross transactions on the client’s behalf. Before that consent is signed, the adviser must provide full written disclosure explaining that it will act as broker for both parties, will collect compensation from both sides, and will face a conflicting division of loyalties as a result.²

Every disclosure document and confirmation must carry a conspicuous statement telling the client they can revoke this consent at any time by written notice to the adviser.² The rule does not set a deadline for how quickly the adviser must stop executing crosses after a revocation, but the underlying duty to follow client instructions makes any real delay a problem.

Confirmations at or Before Completion

Prospective consent does not end the paperwork. The adviser must send a written confirmation at or before the completion of each agency cross transaction. Each confirmation must state:

The nature of the transaction and the date it took place.
The source and amount of any commissions or other compensation the adviser received or will receive from the trade.
An offer to furnish, on request, the exact time the transaction occurred.
A conspicuous reminder that the client may revoke consent at any time in writing.

These confirmations are the client’s running check on whether cross trades are being handled fairly.²

Annual Summary to the Client

At least once a year, the adviser must send each participating client a written statement summarizing all agency cross transactions executed since the last statement, including the total number of such trades and the total commissions or other compensation the adviser received from them.² The summary can accompany or form part of the regular account statement. For clients who don’t read individual confirmations, this is often the first time they see the cumulative cost.

Best Execution Still Applies

Meeting the disclosure mechanics of Rule 206(3)-2 does not relieve the adviser of the separate duty to seek best execution. When an adviser selects the broker-dealer executing a client’s trade, it must ensure the overall terms are the most favorable reasonably available under the circumstances.³ For a cross, that means demonstrating the price was fair to both sides, with documentation to back it up.

Pricing is where firms have gotten into trouble. In one SEC enforcement action, Hamlin Capital Management moved municipal bonds between client accounts at bid prices well above recent trading levels, causing buying clients to overpay by roughly $194,500 while selling clients missed out on approximately $414,672 in potential market savings. Hamlin agreed to reimburse over $609,000 to affected clients and pay a $900,000 civil penalty.³ A cross has to reflect current market conditions, and the adviser has to be able to show it checked.

Internal Cross Trades Without Extra Compensation

Not every trade between two client accounts is an agency cross transaction. When an adviser matches a trade between two advisory clients or funds it manages and collects no compensation beyond its standard advisory fee, the SEC has indicated that Section 206(3) does not apply. These are commonly called internal cross trades.

The line turns on compensation. If the adviser earns commissions directly or indirectly, the trade is an agency cross and must follow Rule 206(3)-2. If the only compensation is the advisory fee the client already pays, the formal consent-and-confirmation framework isn’t required. The fiduciary duty still applies in full, so the firm still needs to document that the trade served both clients’ interests and achieved best execution. Skipping the Rule 206(3)-2 paperwork doesn’t mean skipping the analysis.

ERISA Accounts Are a Separate Track

Advisers managing retirement plan assets face stricter rules. ERISA generally prohibits cross trades, treating any exchange of assets between two accounts managed by the same fiduciary without going through a public market as a prohibited transaction.⁴ Exemptions exist but are narrow, and qualifying requires meeting conditions beyond what Rule 206(3)-2 demands. Compliance with the SEC rule does not automatically satisfy ERISA. Firms handling both ERISA and non-ERISA accounts need to run two separate compliance tracks.

Compliance Failures Examiners Flag

SEC examination staff have called out recurring problems with how advisers handle agency cross transactions in practice:

Advisers disclosed to clients that they would not engage in agency cross transactions, then went ahead and executed numerous cross trades in reliance on Rule 206(3)-2.⁵
Advisers conducted agency cross transactions and claimed to rely on Rule 206(3)-2 but could not produce any records showing they had obtained written consent, sent trade confirmations, or delivered annual disclosures.⁵

The documentation gap is especially damaging. Without records, there is no way to prove compliance, and examiners treat missing records the same as non-compliance. Every undocumented trade sits outside the rule’s safe harbor, which means it sits inside Section 206(3)’s prohibition.
