FINRA Series 7 / 63 / 65 Reg BI (Best Interest)
Last updated: May 2, 2026
Reg BI (Best Interest) questions are one of the highest-leverage areas to study for the FINRA Series 7 / 63 / 65. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Regulation Best Interest (Reg BI), adopted by the SEC under Exchange Act Rule 15l-1 and effective June 30, 2020, requires a broker-dealer or associated person making a recommendation of any securities transaction or investment strategy to a retail customer to act in the retail customer's best interest at the time the recommendation is made, without placing the firm's or registered person's financial or other interest ahead of the retail customer's interest. The general obligation is satisfied only by complying with four component obligations: Disclosure, Care, Conflict of Interest, and Compliance. Reg BI raises the standard above the old FINRA Rule 2111 suitability standard but does NOT impose an ongoing fiduciary duty like the Investment Advisers Act of 1940 imposes on RIAs.
Elements breakdown
Disclosure Obligation
Before or at the time of the recommendation, the broker-dealer must provide the retail customer full and fair written disclosure of all material facts about the relationship and the recommendation.
- Capacity (broker-dealer, not adviser)
- Fees and costs of the transaction
- Type and scope of services provided
- Material limitations on recommendations
- Material conflicts of interest disclosed in writing
Common examples:
- Form CRS delivered at or before account opening
- Disclosure that firm offers only proprietary mutual funds
Care Obligation
The registered person must exercise reasonable diligence, care, and skill to understand the recommendation and to have a reasonable basis to believe it is in the best interest of that particular retail customer based on the customer's investment profile.
- Reasonable basis (product understood generally)
- Customer-specific best interest (fits this customer)
- Series of recommendations not excessive in light of profile
- Cost is a factor — but not the only factor
- Reasonably available alternatives considered
Common examples:
- Comparing share-class costs (A vs. C shares) for a long-term holder
- Documenting why a higher-cost product was selected over a cheaper alternative
Conflict of Interest Obligation
The firm must establish, maintain, and enforce written policies and procedures reasonably designed to identify and at a minimum disclose, or eliminate, all conflicts of interest associated with recommendations.
- Identify all conflicts at firm and rep level
- Disclose or mitigate conflicts tied to financial incentives
- Eliminate sales contests, quotas, bonuses tied to specific securities within a limited period
- Mitigate conflicts that create incentive to place firm interest ahead
- Address material limitations (proprietary-only menus)
Common examples:
- Banning a quarterly contest awarding trips for selling one variable annuity
- Mitigation policy for reps whose payout grid changes mid-year
Compliance Obligation
The broker-dealer (the firm itself, not the individual rep) must establish, maintain, and enforce written policies and procedures reasonably designed to achieve compliance with Reg BI as a whole.
- Firm-level written supervisory procedures
- Training for registered persons
- Surveillance and testing of recommendations
- Recordkeeping demonstrating best-interest analysis
- Remediation when violations occur
Common examples:
- Annual Reg BI training certifications
- Trade-surveillance system flagging high-cost recommendations for review
Scope — Who and What is Covered
Reg BI applies only to recommendations to retail customers by broker-dealers and associated persons; it does not apply to institutional accounts or to RIAs (who are separately governed by the Advisers Act fiduciary duty).
- Retail customer = natural person using recommendation for personal/family/household purposes
- Covers securities transactions AND investment strategies
- Covers account-type recommendations (e.g., rollover into IRA)
- Does NOT impose ongoing monitoring duty by default
- Does NOT cover purely self-directed unsolicited trades
Common patterns and traps
Fiduciary-Conflation Trap
The wrong answer treats Reg BI as if it imposed the same continuous fiduciary duty that the Investment Advisers Act of 1940 imposes on RIAs. Test writers exploit candidates who memorized 'best interest = fiduciary' without nuance. Reg BI is a point-in-time standard tied to a recommendation; it does not, by itself, require ongoing portfolio monitoring.
A choice stating the broker-dealer must continuously monitor the account or owes the same duty as a registered investment adviser.
Suitability-Equivalence Trap
The wrong answer treats Reg BI as identical to the old FINRA Rule 2111 suitability standard. Reg BI is strictly higher — it requires placing the customer's interest ahead of the firm's, considering reasonably available alternatives, and addressing cost as a factor, none of which 2111 expressly required.
A choice that says satisfying FINRA Rule 2111 suitability automatically satisfies Reg BI, or that a recommendation merely needs to be 'suitable' for the customer.
Institutional-Customer Misapplication
The wrong answer applies Reg BI to a corporate, institutional, or accredited entity account. Reg BI's protections run only to retail customers — natural persons (or their legal representatives) using the recommendation primarily for personal, family, or household purposes. Recommendations to a pension plan trustee for plan purposes typically fall outside Reg BI.
A choice claiming Reg BI requires Form CRS delivery to a corporate treasury account, or that institutional clients receive identical Reg BI protections as retail.
Cost-Only Care Trap
The wrong answer says the lowest-cost product is always required, or that recommending a higher-cost product per se violates the Care Obligation. The SEC was explicit: cost is a factor that must be considered, but not the only factor — features, liquidity, tax treatment, and customer needs can justify a costlier product if documented.
A choice asserting the rep must always recommend the cheapest available share class or product, regardless of customer profile.
Sales-Contest Permission Slip
The wrong answer suggests sales contests, quotas, or production-bonus structures tied to specific securities are permissible if disclosed. Reg BI's Conflict of Interest Obligation requires firms to ELIMINATE — not merely disclose — sales contests, quotas, bonuses, and non-cash compensation tied to the sale of specific securities or types of securities within a limited period.
A choice claiming a quarterly trip-incentive for selling a particular variable annuity is fine because the firm disclosed it in writing.
How it works
Think of Reg BI as suitability with teeth. Old FINRA Rule 2111 asked whether a recommendation was suitable for the customer; Reg BI asks whether it was in that customer's best interest at the moment of recommendation, and forces the firm to back that up with disclosure, documentation, conflict mitigation, and supervisory infrastructure. Suppose Yamamoto Wealth Partners, LLC has a registered rep recommending an annuity to a 68-year-old retiree: under Reg BI the rep must understand the product (Care — reasonable basis), determine it fits this specific retiree given liquidity needs and tax bracket (Care — customer-specific), deliver Form CRS and disclose the trail commission in writing (Disclosure), and the firm must have eliminated any sales-contest incentive tied to that annuity family (Conflict of Interest). If any of the four obligations fails, Reg BI is violated even if the recommendation happened to work out. Critically, Reg BI does NOT convert the broker into a fiduciary in the Advisers Act sense — there is no general ongoing duty to monitor the account.
Worked examples
Under Regulation Best Interest, which component obligation has Marisol MOST clearly violated?
- A The Disclosure Obligation, because Class C shares carry a 12b-1 fee that was not disclosed in Form CRS
- B The Care Obligation, because she failed to consider reasonably available alternatives and document why the higher-ongoing-cost share class served the customer's best interest ✓ Correct
- C The Conflict of Interest Obligation, because all 12b-1 fees are prohibited under Reg BI
- D No obligation has been violated because Class C shares are suitable under FINRA Rule 2111 for any retail IRA customer
Why B is correct: The Care Obligation under Reg BI requires the rep to exercise reasonable diligence, care, and skill, including consideration of reasonably available alternatives and the costs of the recommendation. For an 8-year holding period, Class A shares with a one-time 4.25% load and a 0.25% trail will almost certainly be cheaper than Class C shares charging 1.00% annually, and the rep failed to document why she picked the costlier path. Cost is not the only factor, but ignoring it and skipping the documentation the firm's WSPs require is a textbook Care Obligation failure.
Why each wrong choice fails:
- A: Form CRS delivers relationship-level disclosures; product-specific 12b-1 fees are disclosed in the prospectus, not Form CRS. The failure here is the absence of comparative analysis, not a missing CRS disclosure.
- C: Reg BI does not prohibit 12b-1 fees; they remain lawful under Investment Company Act Rule 12b-1. The Conflict of Interest Obligation requires firms to identify and address conflicts, not to ban routine fund expenses. (Sales-Contest Permission Slip)
- D: Reg BI is strictly higher than FINRA Rule 2111 suitability; satisfying old suitability does not satisfy Reg BI. A recommendation can be 'suitable' yet still violate the customer-specific best-interest prong of the Care Obligation. (Suitability-Equivalence Trap)
Which of the following statements is TRUE regarding Reg BI's application to the Northvale recommendation?
- A Reg BI applies in full because Northvale is a customer of a broker-dealer making a securities recommendation
- B Reg BI applies only to the Disclosure Obligation but not the Care Obligation when the customer is a corporation
- C Reg BI does not apply because Northvale is not a retail customer; the recommendation is outside Reg BI's scope ✓ Correct
- D Reg BI applies because the Investment Advisers Act fiduciary duty has been incorporated into Reg BI for all institutional accounts
Why C is correct: Reg BI applies only to recommendations made to a 'retail customer,' defined under Rule 15l-1 as a natural person, or the legal representative of a natural person, who uses the recommendation primarily for personal, family, or household purposes. Northvale is a corporation using the recommendation for business operating cash, so it falls outside the retail-customer definition entirely. Other rules (FINRA Rule 2111 institutional suitability, antifraud rules) still apply, but Reg BI's four obligations do not.
Why each wrong choice fails:
- A: Reg BI does not apply to every broker-dealer customer; its scope is limited by the retail-customer definition. Corporate accounts using recommendations for business purposes are excluded. (Institutional-Customer Misapplication)
- B: Reg BI's component obligations are not severable by customer type — either the customer is retail (and all four apply) or not (and none apply). There is no 'disclosure-only' partial application for corporations. (Institutional-Customer Misapplication)
- D: Reg BI did not incorporate the Advisers Act fiduciary duty, and certainly not for institutional accounts. The Advisers Act fiduciary duty applies to RIAs vis-à-vis their advisory clients, which is a separate regulatory track. (Fiduciary-Conflation Trap)
Under Reg BI's Conflict of Interest Obligation, which response is MOST accurate?
- A The program is permissible as long as the written disclosure is delivered before or at the time of the recommendation
- B The program must be eliminated, not merely disclosed, because Reg BI requires firms to eliminate sales contests, quotas, bonuses, and non-cash compensation tied to specific securities within a limited period ✓ Correct
- C The program is permissible because Reg BI permits any conflict of interest provided the firm has written policies and procedures
- D The program is permissible only if the firm also offers an equivalent contest for non-proprietary annuities
Why B is correct: Reg BI's Conflict of Interest Obligation requires firms to establish written policies reasonably designed to ELIMINATE — not merely disclose or mitigate — sales contests, sales quotas, bonuses, and non-cash compensation that are based on the sale of specific securities or specific types of securities within a limited period of time. A quarterly cash-and-trip incentive tied to one proprietary variable annuity falls squarely within that elimination requirement, and no amount of disclosure cures it.
Why each wrong choice fails:
- A: Disclosure cannot cure conflicts that Reg BI requires firms to eliminate. Time-bound, product-specific sales contests are in the 'must eliminate' bucket, not the 'must disclose' bucket. (Sales-Contest Permission Slip)
- C: Reg BI does not permit any conflict so long as procedures exist; specific categories of conflicts (time-bound product-specific contests, quotas, bonuses) must be eliminated outright. Written procedures address the universe of conflicts but cannot override the elimination mandate. (Sales-Contest Permission Slip)
- D: Offering a parallel contest for other products does not cure the prohibited structure — both contests would still be impermissible time-bound product-specific incentives. Reg BI targets the structure of the incentive, not its exclusivity. (Sales-Contest Permission Slip)
Memory aid
Four C's of Reg BI: **C**RS-disclose, **C**are (reasonable basis + customer-specific), **C**onflicts (identify, disclose, mitigate, eliminate sales contests), **C**ompliance (firm-level WSPs).
Key distinction
Reg BI applies a best-interest standard at the time of recommendation by a broker-dealer to a retail customer; the Investment Advisers Act of 1940 imposes an ongoing fiduciary duty on RIAs to all advisory clients regardless of retail status.
Summary
Reg BI requires broker-dealers to act in a retail customer's best interest at the moment of recommendation by satisfying four component obligations — Disclosure, Care, Conflict of Interest, and Compliance — but stops short of imposing the ongoing fiduciary duty that governs investment advisers.
