Standards of Commercial Honor and Principles of Trade
FINRA Rule 2010 — Standards of Commercial Honor and Principles of Trade — is the foundational ethical conduct standard of the entire FINRA rulebook, stated in its entirety in a single sentence that reads: a member, in the conduct of its business, shall observe high standards of commercial honor and just and equitable principles of trade.
Twenty-two words of operative text. No definitions. No specified prohibited conduct. No enumerated list of violations. Yet Rule 2010 is simultaneously one of the shortest rules in the FINRA rulebook and one of the most powerful — invoked by FINRA's Department of Enforcement in virtually every disciplinary proceeding as the foundational authority for sanctioning conduct that falls below the ethical standards expected of every securities industry professional, regardless of whether that conduct constitutes a violation of any more specific FINRA rule, SEC regulation, or federal statute.
Rule 2010's power comes precisely from its breadth. By establishing a principles-based standard rather than a rules-based list of prohibited conduct, FINRA created a regulatory authority that can reach any form of unethical, dishonest, or improper conduct in connection with the securities business — without requiring the advance identification and codification of every specific form of misconduct that might occur in a complex and constantly evolving industry.
It is the catch-all rule that ensures no gap exists in the ethical framework governing the conduct of FINRA member firms and their associated persons.
The Two Standards — Commercial Honor and Just and Equitable Principles
Rule 2010 establishes two distinct but related standards that together constitute the ethical foundation of the securities industry conduct framework.
High standards of commercial honor — the first standard — requires member firms and associated persons to conduct their business with the honesty, integrity, and good faith that characterise ethical commercial practice.
Commercial honor encompasses the obligation to deal truthfully with customers, counterparties, employers, and regulators — to keep commitments, to disclose material information when required, to avoid deception in all its forms, and to conduct the securities business with the same integrity that legitimate commerce has always required of its participants.
A registered representative who misrepresents the risks of an investment to a customer — even if the misrepresentation does not rise to the level of actionable fraud under the Securities Exchange Act of 1934 — has violated the commercial honor standard of Rule 2010.
Just and equitable principles of trade — the second standard — requires that all securities dealings, trading activity, and business practices embody the impartiality, fairness, and good faith that legitimate market participation demands.
The just and equitable principles of trade standard addresses not only the content of individual transactions but the broader framework of fair dealing within which the entire securities market functions — requiring that no participant gain advantage through means that undermine the integrity and fairness of the market system on which investors and issuers alike depend.
Bad Faith, Scienter and Unethical Conduct
The Securities and Exchange Commission, reviewing discipline imposed under the just and equitable principles standard, has long applied a disjunctive test: a violation may be established by a finding either of bad faith or of unethical conduct. In Thomas W. Heath III, decided in 2009 under the New York Stock Exchange's parallel just and equitable principles rule and drawing on the Commission's NASD precedents, the Commission rejected the argument that liability must be premised on a finding of bad faith — the standard focuses on the professional's conduct rather than on a subjective inquiry into intent or state of mind, so a violation need not rest on a finding of motive or scienter, as earlier NASD cases had held even where the just and equitable principles rule was the only rule found to have been violated.
The Commission has described the standard as an industry backstop for the representation inherent in the relationship between a securities professional and a customer — that the customer will be dealt with fairly and in accordance with the standards of the profession — and has repeatedly held that the breach of a securities professional's duty to a client is sufficient to sustain a violation, the analysis being driven by fiduciary principles that require industry professionals to put their clients' interests above their own. Heath, an investment banker about to join another firm, had disclosed material non-public information about a client's pending acquisition to a future colleague, for the self-interested purpose of gaining that colleague's trust and without any malevolent or deceitful quality; the duty of confidentiality he breached was grounded in fiduciary principles and codified in his firm's code of conduct, and the finding against him was sustained.
In deciding whether conduct offends the professional standards of ethics that the rule covers, the Commission has also looked to a firm's own internal compliance policies — sustaining a violation, for example, where a person failed to adhere to the limits on options trading set by the firm's compliance policy.
Breach of Contract, Agency Duties and Payments Due to Clients
The disjunctive test carries one long-standing qualification. A breach of contract alone is not automatically unethical conduct in violation of the rule: as the Commission put it in Southern Brokerage, it is not the function of the NASD under the rule to adjudicate private contract disputes, and not every failure to perform a contract violates the rule — it must also appear that the failure was unethical or dishonorable, or that the breach was committed without equitable excuse or justification. Where the alleged misconduct is a breach of contract in and of itself, the Commission has continued to treat bad faith as the measure of liability, and it has credited equitable excuses to reverse findings, as where a person failed to repay a debt to a former employer after that debt had been forgiven.
Deliberate conduct towards clients stands on a different footing. In Daniel Joseph Alderman the Commission held that the deliberate withholding of payments due to clients for over two months violated the rule, which was promulgated to discipline a wide variety of conduct that may operate as an injustice to investors or other participants in the marketplace.
Duties drawn from the general law of agency can supply the content of the standard where no rule speaks. In Louis Feldman the Commission found the rule violated by a transfer of customer accounts to a new firm without the customers' prior consent, although no specific NASD rule addressed such a transfer, because under fundamental principles of agency law that prior consent is required.
Rule 2010 as the Catch-All Enforcement Authority
The practical importance of Rule 2010 in FINRA's enforcement programme cannot be overstated.
Because the rule establishes a broad principles-based standard rather than enumerating specific prohibited conduct, FINRA can invoke it against virtually any form of unethical or improper conduct in connection with the securities business — including conduct that violates other specific FINRA rules and conduct that violates no specific rule but nonetheless falls below the ethical standards the industry demands.
FINRA's Department of Enforcement typically charges Rule 2010 violations alongside more specific rule violations in disciplinary proceedings — adding the foundational ethical standard charge to the specific regulatory violation charges to ensure that the full ethical dimension of the misconduct is captured in the disciplinary record.
In cases where conduct is clearly unethical but does not fall precisely within the scope of a more specific rule, Rule 2010 standing alone provides the enforcement authority needed to impose appropriate discipline.
The types of conduct that FINRA has charged as Rule 2010 violations span an extraordinarily wide range — from the most serious fraudulent schemes to relatively minor violations of professional standards that nonetheless fall below the commercial honor expected of securities industry participants.
Charging a customer excessive commissions, making unsuitable recommendations without adequate customer profile information, unauthorised trading in customer accounts, submitting false regulatory filings, misappropriating customer funds, sharing examination content in violation of FINRA Rule 1210's rules of conduct, and engaging in outside business activities without required disclosure under FINRA Rule 3270 — all of these have been charged as Rule 2010 violations.
The Business Connection Requirement
The primary limitation on Rule 2010's reach is the requirement that the misconduct occur in the conduct of the member's business — a connection requirement that FINRA and the courts have consistently interpreted broadly rather than narrowly.
Rule 2010 does not regulate what a member firm or associated person does in their purely personal life disconnected from their securities industry activities.
A registered representative's private hobbies, family relationships, or personal financial decisions — if genuinely unconnected to their securities industry role — are not subject to Rule 2010 discipline.
However the business connection requirement has been interpreted to encompass a remarkably wide range of conduct.
FINRA's adjudicatory bodies have held that the business connection is satisfied if the conduct reflects on the associated person's capacity to comply with the regulatory requirements of the securities business and to fulfil their duties in handling other people's money — a standard that can reach conduct occurring outside the direct context of securities industry employment if it raises questions about the individual's fitness for a position of trust and financial responsibility.
A registered representative who commits mortgage fraud on their personal home purchase may be subject to Rule 2010 discipline — not because mortgage fraud is a securities industry violation but because the dishonesty it reflects raises legitimate questions about the individual's fitness to serve in a position of trust in the securities industry.
A registered representative who uses their securities industry employer's systems to access confidential customer information for personal benefit — even without directly harming those customers — has violated Rule 2010 because the misuse of professional access for personal advantage is fundamentally inconsistent with the commercial honor standard.
Conduct Away From Customers and Securities Transactions
The Commission's decisions show how far the business connection reaches beyond customers and securities. The rule encompasses business-related conduct inconsistent with just and equitable principles of trade even if that activity does not involve a security, and the misconduct need not relate to the associated person's customers or to a securities transaction. In Leonard John Ialeggio an associated person employed by his member firm's parent company obtained reimbursement from the parent for expenses he had not incurred and improperly induced it to pay his country club initiation fees; the Commission held that the rule could apply to misconduct not related directly to the securities industry, even where no customer was involved and no customer's funds were jeopardised or misappropriated, and the Ninth Circuit affirmed that cheating his employer was in the conduct of his business although the employer cheated was the parent company rather than the member firm itself.
A position of financial trust outside the securities business can itself make conduct business-related. In Vail the Fifth Circuit upheld discipline of a securities salesman who misappropriated funds from a political club and misrepresented that the funds were held in an account at the member firm where he worked, holding that his position as a fiduciary of the club managing the club's funds constituted business-related conduct — a basis for the finding separate from his misrepresentations about the account.
Attempts to narrow the test have failed. In Stephen Grivas, decided in 2016, the Commission rejected the argument that misconduct must bear a close relationship to the associated person's investment banking or securities business, observing that the language is not in Rule 2010 and is contrary to the precedent interpreting it, and it declined to borrow limits from cases on the scope of FINRA's arbitration rules, because a disciplinary proceeding is governed by FINRA's Code of Procedure rather than its Code of Arbitration Procedure. Nor is the question one of FINRA's jurisdiction: whether FINRA may sanction particular conduct under Rule 2010 is a merits question about what the rule prohibits.
Rule 2010 and the Anti-Fraud Framework
Rule 2010 operates alongside — not in place of — the anti-fraud provisions of the Securities Exchange Act of 1934 and FINRA Rule 2020.
The relationship among these three authorities reflects the layered nature of the securities regulatory framework.
Section 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 establish the federal anti-fraud prohibition — making it unlawful to employ any device, scheme, or artifice to defraud or to make any untrue statement of a material fact in connection with the purchase or sale of any security.
FINRA Rule 2020 parallels this prohibition at the self-regulatory organisation level — prohibiting the use of manipulative, deceptive, or other fraudulent devices in connection with securities transactions. Rule 2010 operates at a higher level of generality — reaching unethical conduct that may not rise to the level of fraud but that nonetheless falls below the standards of commercial honor and just and equitable principles of trade.
This layered structure ensures comprehensive coverage — the most serious fraudulent conduct is addressed by both federal securities law and FINRA Rule 2020, while less serious but nonetheless unethical conduct is addressed by Rule 2010's broader principles-based standard.
The result is that virtually no form of improper conduct in connection with the securities business falls outside the reach of the combined regulatory framework.
Rule 2010 and the Suitability and Best Interest Obligations
Rule 2010 provides an additional layer of enforcement authority supporting the suitability obligations of FINRA Rule 2111 and the best interest standard of Regulation Best Interest — meaning that a registered representative who makes unsuitable recommendations or fails to act in a retail customer's best interest may face both the specific rule violation and an overarching Rule 2010 charge.
The relationship between Rule 2010 and FINRA Rule 2111 is well established in FINRA's enforcement history — registered representatives who make systematic unsuitable recommendations, who churn customer accounts through excessive trading, or who misrepresent the nature or risks of recommended products are routinely charged with both the specific suitability rule violation and the foundational commercial honour violation of Rule 2010.
This dual charging practice reflects FINRA's view that unsuitable recommendations and best interest failures are not merely technical regulatory violations — they are fundamentally inconsistent with the ethical principles that should govern every aspect of a registered representative's relationship with the customers whose financial wellbeing they have been entrusted to serve.
Conversion of Funds or Securities
Conversion is among the most serious conduct charged under Rule 2010. The FINRA Sanction Guidelines define it as the intentional and unauthorised taking of and/or exercise of ownership over property by one who neither owns the property nor is entitled to possess it, and the Commission applies that definition in reviewing FINRA decisions, testing each element in turn — whether the taking was intentional, whether it was authorised, and whether the property belonged to the respondent or he was entitled to possess it.
The guideline for conversion recommends no fine, because a bar is standard, and directs adjudicators to bar the respondent regardless of the amount converted — an approach the Commission has explained as reflecting the judgment that, absent mitigating factors, conversion poses so substantial a risk to investors or the markets as to render the violator unfit for employment in the securities industry.
In Grivas the respondent, who managed an investment fund, transferred 280,000 dollars of the fund's money without authorisation, through a series of intermediaries he controlled, to the broker-dealer with which he was associated, in order to cure that firm's net capital deficiency. The Commission held that the transfer was conversion, that its ultimate purpose of benefiting the member firm placed it squarely within the conduct of his business, and that the indirect route, far from helping him, suggested that he was trying to hide the conversion and knew the conduct was prohibited.
Forgery, Signatures and Falsified Records
FINRA treats signing someone else's name to a document as a violation of Rule 2010 when it is a forgery or a falsification. Forgery occurs when one person signs or affixes, or causes to be signed or affixed, another person's name or initials on a document without the other person's prior permission; falsification occurs when a person creates a document or an entry in a firm's system that creates a false appearance by including altered or untrue information.
The conduct is not confined to customers' signatures. In Regulatory Notice 22-18, published in August 2022, FINRA reported an increasing number of cases of representatives forging or falsifying customer signatures, and in some cases the signatures of colleagues or supervisors, through third-party digital signature platforms, on documents ranging from account opening forms, discretionary trading authorisations and wire instructions to internal firm documents used to review customer transactions — in some instances directing administrative staff to manipulate the digital signature process in what the representatives claimed were acceptable accommodations to the customer.
The Sanction Guidelines' entry for forgery, unauthorised use of signatures or falsification of records weighs, among other things, whether the respondent had a good-faith but mistaken belief of express or implied authority, whether the customer possessed or saw the document before the signature was affixed, and whether the misconduct assisted a customer's or a third party's wrongdoing. Where mitigating factors predominate — signatures and falsifications in connection with authorised transactions, or a customer who re-signed the document or otherwise approved the signature after the fact — it suggests a suspension of 10 business days to six months; where aggravating factors predominate, particularly in cases resulting in customer harm, a suspension of six months to two years or a bar.
Settling Customer Complaints Away From the Firm
Settling a customer's complaint away from the firm is a distinct category of Rule 2010 conduct in the Sanction Guidelines. The Commission sustained such a violation in Dan Adlai Druz, where the respondent had settled customer complaints without notifying his firm's legal department, and the D.C. Circuit affirmed. The Guidelines place the category among the forms of impeding regulatory investigations, alongside the failure to respond to requests for information made under FINRA Rule 8210.
The guideline's first specific consideration is whether the respondent gave the employer firm notice of the settlement and the firm acquiesced, or whether the respondent deceived the firm. Its second is whether the respondent's actions delayed or prevented the filing of required Forms U4 or U5 or of reports under FINRA Rule 4530.
The guideline recommends a fine of 2,500 to 20,000 dollars and a suspension in any or all capacities of up to two years, and it directs adjudicators to consider barring the respondent where aggravating factors predominate.
Sanctions Under Rule 2010
FINRA's disciplinary authority under Rule 2010 encompasses the full range of sanctions available for violations of the FINRA rulebook — from letters of caution and fines for less serious violations to suspension and permanent bar from the securities industry for the most serious misconduct.
The sanctions imposed for Rule 2010 violations reflect the severity, scope, and impact of the underlying misconduct — a registered representative who makes a single unsuitable recommendation may receive a fine and a short suspension, while one who systematically defrauds customers over an extended period will typically receive a permanent bar. The FINRA Sanctions Guidelines — while not binding — provide guidance on the appropriate range of sanctions for various categories of misconduct, giving FINRA's adjudicatory panels a framework for ensuring consistent and proportionate discipline across cases.
Improper Use, Late Repayment and Prior Termination
The Sanction Guidelines distinguish conversion from the improper use of funds or securities. For improper use they recommend that adjudicators consider a bar, but where the improper use resulted from the respondent's misunderstanding of the intended use of the funds or securities, or other mitigation exists, a suspension in any or all capacities of three months to two years and thereafter until the respondent pays restitution.
Repayment counts for little when it comes late. Among the principal considerations applied in every case is whether the respondent voluntarily and reasonably attempted, prior to detection and intervention, to pay restitution or otherwise remedy the misconduct; in Grivas, where the converted money was repaid almost eleven months after the transfer and only after FINRA had begun its investigation, the Commission found that the repayment had little if any mitigating effect.
A firm's own response does not necessarily spare the respondent either. Under the Guidelines' general principles, a respondent who seeks mitigation from the firm's earlier termination of his employment for the same misconduct bears the burden of proving that the termination materially reduced the likelihood of future misconduct; where the misconduct is serious, adjudicators may still impose a bar, and the time taken to regain employment, the loss of salary and the other impacts of termination are collateral consequences that should not be considered mitigating.
Examination Relevance and Key Takeaways
FINRA Rule 2010 is not tied by FINRA's own content outlines to the Series 7 and Series 65 examinations — the Series 65 is a NASAA examination that FINRA administers, and FINRA's Series 7 outline does not list the rule — but FINRA's content outline for the Securities Industry Essentials examination, the general knowledge co-requisite for the Series 7, lists it among the FINRA rules as the foundational ethical conduct standard of the FINRA rulebook — the principles-based catch-all rule that establishes the baseline of commercial honour and fair dealing expected of every securities industry professional.
The key points to retain are these.
FINRA Rule 2010 — Standards of Commercial Honor and Principles of Trade — requires every member firm and associated person to observe high standards of commercial honor and just and equitable principles of trade in the conduct of their business. The rule is stated in a single sentence and contains no enumerated list of prohibited conduct — its power comes from its breadth as a principles-based standard that FINRA can apply to virtually any form of unethical or improper conduct in connection with the securities business.
Rule 2010 is the foundational catch-all enforcement authority invoked by FINRA's Department of Enforcement in virtually every disciplinary proceeding — applicable both alongside specific rule violations and as a standalone charge against unethical conduct that falls below commercial honor standards even when no more specific rule is directly violated.
The primary limitation is the business connection requirement — the misconduct must occur in the conduct of the member's business — but this has been interpreted broadly to include conduct that reflects on the individual's fitness for a position of trust in the securities industry even when it occurs outside the direct context of securities employment.
Rule 2010 operates alongside the federal anti-fraud provisions of Section 10(b) of the Securities Exchange Act of 1934, SEC Rule 10b-5, and FINRA Rule 2020 — providing principles-based coverage of unethical conduct that may not rise to the level of actionable fraud under the more specific anti-fraud provisions.
