Why this Matters to Investors (Regulation Best Interest)
Regulation Best Interest (Reg BI) is a U.S. securities regulation designed to strengthen the standard of conduct that broker-dealers owe to retail investors when making recommendations about securities transactions or investment strategies. Adopted by the U.S. Securities and Exchange Commission and effective as of June 30, 2020, Reg BI aims to enhance investor protection while preserving investor access to brokerage products and services.
Reg BI requires broker-dealers and financial advisors to act in the best interest of the retail customer at the time a recommendation is made, and not to place their own financial or other interests ahead of the customer’s. This represents a higher standard than the historical “suitability” requirement, which only required that recommendations be suitable, not necessarily optimal or conflict-free.
Reg BI is built around four key obligations:
- Disclosure Obligation – Broker-dealers must disclose material facts about the relationship and recommendations, including fees, scope of services, and conflicts of interest.
- Care Obligation – Recommendations must be made with reasonable diligence, care, and skill, considering costs, risks, and alternatives.
- Conflict of Interest Obligation – Firms must identify, disclose, and mitigate or eliminate conflicts, particularly those that create incentives to favor one product over another.
- Compliance Obligation – Firms must establish policies and procedures designed to ensure compliance with Reg BI as a whole.
Importantly, Reg BI applies at the recommendation level, not as a continuous duty like the fiduciary standard applicable to registered investment advisers. Still, it significantly narrows the gap by emphasizing cost considerations, conflict management, and investor-focused decision-making.
Overall, Regulation Best Interest seeks to promote transparency, improve the quality of investment recommendations, and reinforce trust between retail investors and broker-dealers in the U.S. securities markets.
