Rule Summary #1: FINRA Rule 2111 (Suitability)

FINRA Rule 2111 (Suitability) requires a reasonable basis for each recommendation. A broker should match a recommendation to the customer’s profile, including risk tolerance, time horizon, and liquidity needs.

Rule Summary #2: FINRA Rule 2090 (Know Your Customer)

FINRA Rule 2090 (Know Your Customer) requires firms and brokers to use reasonable diligence to know the essential facts about each customer. That duty helps support recommendations that fit the customer’s needs and account authority.

Why This Matters to Investors (Regulation Best Interest)

Regulation Best Interest (Reg BI) is a U.S. securities regulation. It strengthens the standard of conduct that broker-dealers owe to retail investors. It applies when they recommend securities transactions or investment strategies. The U.S. Securities and Exchange Commission adopted Reg BI. It became effective on June 30, 2020. Reg BI aims to protect investors while preserving access to brokerage products and services.

Reg BI requires broker-dealers and financial advisors to act in a retail customer’s best interest at the time of a recommendation. They must not place their own financial or other interests ahead of the customer’s. This standard is higher than the older “suitability” rule. Suitability meant a recommendation only had to be appropriate. It did not have to be the best option or free of conflicts.

Reg BI has four key obligations:

Disclosure Obligation – Broker-dealers must disclose material facts about the relationship and the recommendation. This includes fees, the scope of services, and conflicts of interest.

Care Obligation – Broker-dealers must use reasonable diligence, care, and skill. They must consider costs, risks, and alternatives when making a recommendation.

Conflict of Interest Obligation – Firms must identify conflicts of interest. They must disclose them and mitigate or eliminate them. This includes conflicts that create incentives to favor one product over another.

Compliance Obligation – Firms must maintain policies and procedures. Those policies should be designed to ensure compliance with Reg BI as a whole.

Reg BI applies to each recommendation. It is not a continuous duty like the fiduciary standard for registered investment advisers. Even so, it narrows the gap. It puts more focus on costs, conflicts, and investor-focused decision-making.

Overall, Regulation Best Interest promotes transparency. It also aims to improve the quality of investment recommendations. It is designed to reinforce trust between retail investors and broker-dealers in the U.S. securities markets.
