Reg BI (Regulation Best Interest)
The SEC standard that requires broker-dealers to act in the customer's best interest at recommendation time.
Why it matters
Reg BI replaced the older suitability standard in 2020. It requires disclosure of conflicts, care obligations, and reasonable diligence — but is generally considered weaker than a full fiduciary duty because it applies only at recommendation, not ongoing.
