Regulation Best Interest: Reg BI Standard for Brokers

Key Takeaways

• Regulation Best Interest requires brokers to put the retail customer's interest ahead of their own when recommending.
• The rule is met only by satisfying four obligations: Disclosure, Care, Conflict of Interest, and Compliance.
• Reg BI is stronger than suitability but is not identical to the investment adviser fiduciary standard.
• A common mistake is assuming "best interest" forbids any conflict, when it requires managing and disclosing them.

What It Is

Regulation Best Interest is an SEC rule, adopted in 2019 and effective in 2020, that governs how broker-dealers recommend securities and accounts to retail customers. It requires the broker to act in the customer's best interest at the time of a recommendation, without placing its own interests ahead of the customer's.

Reg BI replaced the older suitability standard for retail recommendations. Under suitability, a recommendation only had to be suitable for the customer. Reg BI demands more: the recommendation must be in the customer's best interest, judged across four specific obligations.

A "retail customer" is broadly an individual using a recommendation primarily for personal, family, or household purposes. The rule applies to recommendations of securities and of account types, such as choosing a brokerage versus an advisory account.

The Intuition

Brokers earn money in ways that can conflict with what is best for you, such as higher commissions on certain products. The old suitability test allowed a merely acceptable product even when a cheaper, better one existed.

Reg BI tightens that. It says the broker must reasonably believe the recommendation is in your best interest, not just tolerable. Conflicts are not banned, because a commission-based model inherently has them, but they must be identified, disclosed, and in some cases eliminated or mitigated.

The four-part structure makes the standard concrete. Instead of one vague duty, the rule lists what a broker must disclose, the care it must use, how it must handle conflicts, and the systems it must maintain.

How It Works

Reg BI is satisfied only by complying with all four component obligations. The Disclosure Obligation requires the broker to give full and fair written disclosure of material facts about the relationship and about conflicts of interest, before or at the time of the recommendation. Firms typically deliver a relationship summary called Form CRS.

The Care Obligation requires the broker to exercise reasonable diligence, care, and skill to understand the product, reasonably believe it is in the customer's best interest, and avoid putting its interest first. This includes considering cost and reasonably available alternatives.

The Conflict of Interest Obligation requires written policies to identify and address conflicts. Some conflicts must be disclosed, others mitigated, and certain ones, such as sales contests, quotas, bonuses, or non-cash compensation tied to selling specific securities within a limited period, must be eliminated. The Compliance Obligation requires the firm to maintain written policies and procedures reasonably designed to achieve compliance with Reg BI as a whole.

Worked Example

Suppose a broker considers two similar mutual funds for a retail client. Fund A charges 1.0% in annual fees and pays the broker a higher commission. Fund B charges 0.4%, is otherwise comparable, and pays the broker less.

Under the old suitability standard, recommending Fund A might pass if it broadly fit the client. Under Reg BI, the Care Obligation requires the broker to consider cost and reasonably available alternatives. With two comparable funds, recommending the costlier one mainly because it pays the broker more would conflict with acting in the client's best interest.

The broker must also disclose, before or at the recommendation, that it earns more from certain products. The firm needs written conflict policies and compliance systems behind that. Recommending Fund A could still be defensible if it had a genuine advantage for the client, but higher pay to the broker alone is not a valid reason.

Common Mistakes

1. Confusing it with suitability. Reg BI is stronger than the old suitability rule. A recommendation must be in the customer's best interest, not merely acceptable.

2. Thinking it bans all conflicts. Conflicts are allowed but must be disclosed and managed, and some must be eliminated. The rule is about handling conflicts, not pretending they do not exist.

3. Equating it with fiduciary duty. Reg BI applies at the time of a recommendation, while an adviser's fiduciary duty is ongoing. The SEC describes them as different standards.

4. Ignoring cost and alternatives. The Care Obligation requires weighing cost and reasonably available alternatives. Recommending a pricier product without that analysis is a frequent gap.

5. Skipping Form CRS or written policies. Disclosure and compliance are obligations, not optional. Failing to deliver the relationship summary or maintain procedures violates the rule.

Frequently Asked Questions

What is Regulation Best Interest in simple terms? Regulation Best Interest requires a broker to recommend what is best for you, not just what is acceptable, and not to put its own profit first. It applies whenever a broker makes a recommendation to a retail customer.

How does Regulation Best Interest affect investment decisions? It pushes brokers to weigh cost and better alternatives and to disclose how they get paid. That gives you clearer information to judge whether a recommendation truly fits your situation.

What is a real-world example of Regulation Best Interest? If two similar funds exist and one costs less but pays the broker less, recommending the pricier one mainly for the higher commission would conflict with Reg BI. The broker must consider cost and alternatives.

How can investors use Regulation Best Interest effectively? Read the Form CRS relationship summary and ask directly how your broker is paid on a recommendation. Comparing costs and alternatives yourself reinforces the protection the rule provides.

How is Regulation Best Interest different from FINRA Rule 5310? Reg BI governs whether a recommendation is in your best interest before you act. FINRA Rule 5310 governs how your order is then executed to obtain the best available terms.
