Regulation Best Interest is not new. It has been in effect since June 30, 2020. What is new in 2026 is the enforcement and exam signal around it. On May 27, 2026, the SEC announced a settled action against a broker-dealer, David Lerner Associates, tied to Regulation Best Interest, including findings related to mutual fund switch recommendations and the firm's written policies around its "Customized Investment Plans." At the same time, the SEC's 2026 Examination Priorities and FINRA's 2026 Annual Regulatory Oversight Report continue to treat Reg BI as a live supervision and sales-practice issue, not a box-checking exercise.
For early-career finance professionals, that matters for two reasons. If you are heading into a client-facing brokerage role, Reg BI will shape how recommendations are reviewed, documented, and supervised. If you are studying for the SIE, Series 7, Series 63, Series 65, or Series 66, this is one of those subjects where the exam concept and the real-world compliance expectation line up unusually well.
Why Reg BI is back in focus in 2026
The timely development is the SEC's May 27, 2026 settled order against David Lerner Associates. According to the SEC's published summary, the firm failed in two areas. First, the order says representatives recommended at least 253 mutual fund switches that imposed new upfront sales charges without adequately considering cost, including the availability of alternatives within the same fund family. Second, the SEC said the firm lacked written policies and procedures reasonably designed to achieve compliance with Reg BI for its Customized Investment Plans, which were individualized investment plans presented to retail customers.
That case did not announce a new rule. It was an enforcement action applying an existing one. But that is why it matters: enforcement actions show what regulators think is worth testing in the field.
The SEC's FY 2026 Examination Priorities say broker-dealer exams will continue to focus on retail sales practices, including recommendations involving account types, rollovers, limited product menus, reasonably available alternatives, and the firm's process for satisfying the Care Obligation. FINRA's 2026 Oversight Report makes a similar point from the supervisory side: the rule is still generating findings around product switches, complex products, conflicts, documentation, and the design of surveillance and written procedures.
Quick refresher: what Reg BI actually requires
Reg BI applies when a broker-dealer or associated person makes a recommendation to a retail customer involving a securities transaction or investment strategy, including account recommendations. The SEC's compliance guide emphasizes that the general obligation is met only if the firm complies with four component obligations.
- Disclosure Obligation: provide required written disclosure about the relationship, services, fees, costs, and material conflicts before or at the time of the recommendation.
- Care Obligation: exercise reasonable diligence, care, and skill when making the recommendation.
- Conflict of Interest Obligation: establish, maintain, and enforce written policies and procedures reasonably designed to address conflicts.
- Compliance Obligation: establish, maintain, and enforce written policies and procedures reasonably designed to achieve overall compliance with Reg BI.
Two points are easy to miss if you only memorize the headline. First, Reg BI cannot be satisfied by disclosure alone. Second, the definition of recommendation is broader than a simple "buy this stock" statement. The SEC's guidance explains that account recommendations count, rollover recommendations count, and agreed-upon account monitoring can create implicit hold recommendations that also fall within the rule.
Exam note: For SIE, Series 7, and Series 66 prep, know both the four obligations and the fact pattern triggers. If a question describes a representative recommending an account type, a rollover, a switch, or ongoing monitoring, you should be thinking about Reg BI.
What the latest SEC case suggests firms should be rechecking
The David Lerner Associates matter is especially useful because it highlights two recurring pressure points: cost analysis and policy design.
On cost, the SEC's summary says the challenged recommendations involved customers selling Class A mutual fund shares held for less than one year and then buying Class A shares in a different fund family, creating new upfront sales charges. In plain English, the regulator is signaling that "the product is generally suitable" is not enough. If a switch causes the customer to pay fresh charges, lose benefits, or move into a substantially similar position at higher cost, regulators will expect a real comparison and a reason the move was in the customer's best interest.
On policy design, the case is a reminder that custom-looking materials can still create standardized compliance risk. If a firm uses planning tools, model outputs, or individualized plan templates with retail customers, regulators may ask whether those materials are functioning as recommendations. If they are, the written procedures need to reflect that reality.
In many firms, the riskiest recommendation is not the dramatic one. It is the ordinary-seeming one that gets repeated at scale: moving from one fund to another, recommending an IRA rollover, steering a client toward a higher-cost option, or presenting a planning document without understanding when it crosses into a recommendation.
How FINRA and SEC exam teams are framing the issue
FINRA's 2026 Reg BI and Form CRS report is practical reading because it turns abstract obligations into observable failures. Among the findings FINRA highlights are recommendations without a reasonable basis to believe they were in the retail customer's best interest, recommendations of complex or risky products that do not align with the customer's investment profile, and product or account replacements where firms did not adequately consider costs, penalties, surrender periods, tax consequences, or the loss of existing benefits.
FINRA also points to conflicts work that many firms still underbuild. The report describes failures to identify and mitigate incentives that might push an associated person toward recommendations that favor the firm or the representative over the customer. It then contrasts those failures with effective practices such as tailored conflicts matrices, flatter payout structures within product types, and broader prohibitions on sales contests.
The SEC's exam priorities add another operational layer. The Division says it will continue examining how firms review reasonably available alternatives, how they handle recommendations involving limited product menus, and how they satisfy the Care Obligation for complex or tax-advantaged products such as variable annuities, registered index-linked annuities, private placements, 529 plans, and other products with complicated fees or return structures. That is a useful clue for both compliance staff and candidates: the rule is not tested in a vacuum. It is tested in the context of specific product types and customer profiles.
Exam note: If you see a question involving a rollover, a switch, a complex product, a concentrated recommendation, or a recommendation to an older retail client, slow down. Those are common Reg BI testing patterns because they force you to analyze cost, conflicts, customer profile, and disclosure together.
Practical takeaways for new reps
If you are new to the industry, the safest approach is to build good habits before a manager or examiner has to ask for them.
- Know when you are making a recommendation. A personalized "suggested allocation," rollover pitch, account-type discussion, or product switch can trigger Reg BI even if the conversation feels informal.
- Treat cost as a core factor. A recommendation that creates new fees, commissions, sales charges, surrender periods, or tax consequences needs a documented reason that is customer-centered, not sales-centered.
- Compare real alternatives. "Reasonably available alternatives" does not mean every product in the market, but it does mean you should understand the relevant options your firm makes available and why one was chosen over another.
- Do not rely on disclosure as a cure-all. Handing over a disclosure document or Form CRS does not fix a recommendation that was poorly analyzed or conflicted.
- Use approved materials carefully. If a planning tool, proposal system, or slide deck is individualized for a client, assume supervisors and regulators may treat it as part of the recommendation process.
- Document what mattered. The customer's investment profile, risk tolerance, time horizon, liquidity needs, costs, and the alternative paths considered should not live only in your memory.
New professionals sometimes confuse suitability-era instincts with Reg BI expectations. Suitability concepts still matter in the background, but Reg BI asks a sharper question: did the broker-dealer or associated person put the customer's interest first at the time of the recommendation, without placing the firm's or rep's interest ahead of the customer's?
What candidates should remember for the exam
For test day, keep the framework simple.
- Reg BI applies to broker-dealers and associated persons making recommendations to retail customers.
- It covers securities transactions, investment strategies, account recommendations, and certain hold recommendations tied to agreed-upon monitoring.
- The four obligations are Disclosure, Care, Conflict of Interest, and Compliance.
- Form CRS is related but separate. Firms serving retail investors must provide it, but Form CRS does not replace Reg BI analysis.
- Disclosure alone is not enough. That is a classic exam trap.
- Costs, alternatives, conflicts, and the customer's profile are central to the Care Obligation analysis.
If you can recognize those elements in a fact pattern, you will be in good shape not only for the exam but also for the first compliance conversations you have once you are registered.
The bottom line
The 2026 takeaway is straightforward. Reg BI is no longer just a rule you memorize in a licensing course. It is an active enforcement, exam, and supervision theme. The SEC's May 27, 2026 settled action is a reminder that mutual fund switches, individualized client plans, and weak written procedures can still create real exposure. FINRA's 2026 findings show that firms are still missing on product replacements, conflicts, and surveillance.
For candidates and new reps, that is actually useful news. The concepts that matter on the exam are also the ones that matter in practice: understand the recommendation, understand the customer, understand the costs and conflicts, and never assume a disclosure document does the analysis for you.
