## What it does

The skill covers the broker-dealer standard of conduct under SEC Regulation Best Interest: disclosure, care, conflict of interest and compliance. It also owns the question of what triggers a recommendation — explicit advice, account type suggestions, implicit hold recommendations, 401(k) and 403(b) rollovers to an IRA, and strategies involving securities. For the investment adviser fiduciary duty itself or DOL rules, it points to the companion `fiduciary-standards` skill.

Each obligation is broken down against 17 CFR 240.15l-1. The care obligation is split into three levels: understanding the product, matching the customer's investment profile, and weighing reasonably available alternatives. Cost is a factor, not the standard — the skill notes that when two products are substantially similar and one is significantly cheaper, the pricier pick needs a documented reason. The conflict of interest section covers written policies and procedures.

The material is marked current as of June 2026, and the skill itself says to verify effective dates, dollar thresholds and pending rulemakings against current SEC, FINRA and FinCEN sources before advising. Worth checking if you are prepping for an exam or writing up the rationale behind a recommendation.

## When to use it
- decide whether a client conversation counts as a Reg BI recommendation
- review an account type or share class recommendation
- weigh reasonably available alternatives before advising
- document why a costlier product serves the customer better
- check disclosure, care and conflict obligations together

## Example prompts
- Is rolling a 401(k) into an IRA a Reg BI recommendation?
- What alternatives do I need to consider under the care obligation for this share class?
- Compare Reg BI, FINRA suitability and IA fiduciary duty

Use when the user asks whether a broker-dealer recommendation satisfies Reg BI, how to evaluate reasonably available alternatives, rollover recommendation compliance, dual-registrant capacity disclosure, share class or account type recommendations, or Reg BI examination preparation. Also trigger when users mention 'best interest standard for brokers', 'is this a Reg BI recommendation', 'care obligation documentation', 'sales contest elimination requirement', or ask how Reg BI differs from suitability or fiduciary duty.

# SEC Regulation Best Interest (Reg BI)

Regulatory status current as of June 2026 — verify effective dates, dollar thresholds, and pending rulemakings against current SEC/FINRA/FinCEN sources before advising.

## Core Concepts

### What Constitutes a "Recommendation" Under Reg BI
Reg BI applies whenever a broker-dealer or associated person makes a "recommendation" to a "retail customer" of any securities transaction or investment strategy involving securities, including account type recommendations. The SEC adopted the existing FINRA framework for what constitutes a recommendation but expanded its scope:

- **Explicit recommendations:** "You should buy X" or "I recommend allocating to Y."
- **Account type recommendations:** Recommending a brokerage account vs an advisory account, or a specific account type (margin, options-enabled, fee-based).
- **Implicit hold recommendations:** Agreeing with a customer's decision to continue holding a security when the associated person has a duty to monitor or review the account.
- **Rollover recommendations:** Advising a customer to roll assets from an employer plan (401(k), 403(b), pension) to an IRA. The SEC has specifically identified rollovers as triggering Reg BI (see SEC Staff Bulletin on Account Recommendations, 2022).
- **Investment strategy recommendations:** Recommending a strategy involving securities, such as a particular asset allocation, use of leverage, or concentration approach.
```
