Know Your Customer (KYC)
The FINRA Rule 2090 duty of a broker-dealer to use reasonable diligence to know and retain the essential facts about every customer and about the authority of each person acting for that customer. The duty applies when opening and maintaining every account and covers the facts needed to service the account, follow any special handling instructions, understand who may act on it, and comply with applicable laws and rules, including Anti-Money Laundering (AML) requirements. In common usage, KYC also covers the investment profile (age, other investments, financial situation and needs, tax status, investment objectives, investment experience, time horizon, liquidity needs, and risk tolerance), which a broker-dealer must ascertain under the separate suitability obligations: FINRA Rule 2111 or, for a recommendation to a retail customer, Regulation Best Interest. An investment adviser makes a reasonable inquiry into a client's investment objectives, financial situation and needs; the Financial Crimes Enforcement Network rule extending AML programs to most SEC-registered investment advisers and to exempt reporting advisers is scheduled to take effect January 1, 2028. KYC is an ongoing obligation that begins at account opening and requires updates when client circumstances materially change.
During account opening, an investment adviser gathers information showing a client is 45 years old, earns $150,000 annually, has $500,000 in savings, seeks growth with moderate risk, has a 15-year time horizon for retirement, needs $50,000 emergency fund liquidity, has 10 years investment experience, and is in the 32% tax bracket. This complete KYC profile enables suitable investment recommendations.
Students often think KYC is a one-time requirement completed only at account opening, when it is actually an ongoing obligation requiring updates when circumstances change. Others confuse KYC (gathering client information) with suitability (using that information to make appropriate recommendations) or AML (using KYC data to detect suspicious activity). KYC is the foundation that enables both suitability analysis and AML compliance.
How is Know Your Customer (KYC) tested on the exam?
- Identifying the investment profile factors (age, other investments, financial situation and needs, tax status, investment objectives, experience, time horizon, liquidity needs, risk tolerance)
- Understanding when KYC information must be gathered (account opening) and updated (material changes in circumstances)
- Recognizing that inadequate KYC information prevents meeting customer-specific suitability obligations
- Distinguishing between KYC requirements for suitability (investment profile) versus AML requirements (identity verification)
- Understanding that recommendations made without adequate KYC violate both suitability obligations and fiduciary duty
Regulatory limits
Regulatory Limits
| Description | Limit | Notes |
|---|---|---|
| Investment profile factors for suitability (FINRA Rule 2111; the same factors under Regulation Best Interest) | Age, Other investments, Financial situation and needs, Tax status, Investment objectives, Experience, Time horizon, Liquidity needs, Risk tolerance | The profile includes, but is not limited to, these factors and any other information the customer discloses; under Rule 2111 a firm may treat a factor as not relevant only with a reasonable basis documented with specificity |
| KYC verification timing | At account opening and when circumstances materially change | Ongoing obligation, not one-time requirement |
| KYC for AML (Customer Identification Program) | Name, date of birth, residential or business street address, identification number (TIN for a U.S. person) | Verified by documents (such as a government-issued photo ID), non-documentary methods, or both (31 CFR 1023.220) |
Think of KYC like a doctor taking medical history before treatment: You cannot prescribe medication without knowing the patient's conditions, allergies, and health goals. Similarly, you cannot recommend investments without complete client information. Remember "FIT-TLER" for 7 of the profile factors (the suitability rule also lists age and other investments): Financial situation, Investment objectives, Tax status, Time horizon, Liquidity needs, Experience, Risk tolerance. KYC is the foundation that enables suitable recommendations.
Practice questions
Test your understanding with the questions below. Pick an answer to reveal the explanation.
Thomas, a new investment adviser representative, meets with Lisa, a prospective client. During their 15-minute phone call, Lisa mentions she wants "to make money" and has $100,000 to invest. Thomas recommends a portfolio of small-cap growth stocks and emerging market funds without asking about her age, time horizon, risk tolerance, liquidity needs, or financial situation. Two months later, Lisa complains that the portfolio has lost 18% and she needed the money for a home down payment in 6 months. What is Thomas's primary violation?
B is correct. Thomas violated his fundamental Know Your Customer obligation by failing to gather essential client information before making recommendations. Without knowing Lisa's time horizon (6 months, not long-term), liquidity needs (home down payment), risk tolerance, age, or financial situation, Thomas could not determine if small-cap growth stocks and emerging market funds were suitable. The recommendation was unsuitable because the 6-month time horizon and immediate liquidity need make volatile investments inappropriate, but the root violation is inadequate KYC.
A is a disclosure issue but not the primary violation; even with disclosure, recommending volatile investments to someone needing money in 6 months violates suitability. C addresses portfolio construction but misses that without adequate KYC, Thomas had no basis for any recommendation. D concerns ongoing monitoring but the initial recommendation was already unsuitable due to inadequate KYC.
The Series 65 exam tests that adequate Know Your Customer information is the mandatory foundation for meeting suitability obligations. Investment advisers cannot make suitable recommendations without gathering complete information about the client's financial situation, objectives, time horizon, liquidity needs, tax status, experience, and risk tolerance. Failing to gather KYC information before recommending securities is a fundamental violation.
What is the primary purpose of the Know Your Customer (KYC) requirement for investment advisers and broker-dealers?
B is correct. The primary purpose of Know Your Customer requirements is to gather essential client information that enables investment professionals to meet customer-specific suitability obligations (making appropriate recommendations based on the client's investment profile) and, for broker-dealers, comply with Anti-Money Laundering requirements (detecting suspicious activity and verifying identity). The Financial Crimes Enforcement Network rule extending AML programs to most SEC-registered investment advisers and to exempt reporting advisers is scheduled to take effect January 1, 2028. KYC is the foundation for both regulatory compliance areas.
A is incorrect because KYC serves regulatory compliance purposes, not marketing. Using KYC information for marketing without client consent could violate privacy regulations and fiduciary duty. C is incorrect because accredited investor qualification is a separate determination based on income or net worth thresholds, though KYC information may be used in that assessment. D is incorrect because minimum account balances are firm policies, not the regulatory purpose of KYC requirements.
The Series 65 exam tests understanding that KYC serves dual regulatory purposes: enabling suitable investment recommendations and, for broker-dealers, supporting AML compliance. Investment advisers must recognize that gathering complete client information is not optional or for business development, but rather a fundamental regulatory obligation that protects both clients and the integrity of the financial system.
An investment adviser representative gathers the following information from a new client: age 55, married, household income $180,000, current savings $400,000, wants "steady income with some growth," describes himself as "moderately risk-averse," and has 15 years until planned retirement. Which additional KYC information is needed to meet suitability obligations?
A is correct. The adviser has gathered several investment profile factors: age (55), financial situation ($180,000 income, $400,000 savings), investment objectives (steady income with some growth), risk tolerance (moderately risk-averse), and time horizon (15 years until retirement). Still missing are: (1) tax status (tax bracket affects suitability of municipal bonds vs. taxable bonds), (2) liquidity needs (emergency fund requirements, planned large expenses), and (3) investment experience (understanding of investment products and risk). FINRA Rule 2111 and, for a retail customer, Regulation Best Interest name these among the investment profile factors a broker-dealer and its associated persons must use reasonable diligence to ascertain; an investment adviser's suitability duty likewise rests on a reasonable inquiry into the client's investment objectives, financial situation and needs.
B lists information that may be useful for financial planning but are not among the investment profile factors FINRA Rule 2111 names. Employment history and mortgage balance contribute to financial situation but are not separate required factors; credit score is not a suitability factor. C lists factors that may inform recommendations but are not required KYC elements. Political affiliation is never a required factor. D is incorrect because three required factors are missing.
The Series 65 exam tests your ability to identify the client profile factors required for suitability analysis (FIT-TLER covers seven: Financial situation, Investment objectives, Tax status, Time horizon, Liquidity needs, Experience, Risk tolerance; the rule also lists age and other investments). Understanding which factors are required versus helpful prevents inadequate KYC that could lead to unsuitable recommendations.
All of the following are required elements of Know Your Customer information for meeting suitability obligations except
C is correct (the exception). Educational background and degrees earned are not required elements of Know Your Customer information for suitability purposes under FINRA Rule 2111 or Regulation Best Interest. While education may correlate with investment sophistication, the required factor is "investment experience" (knowledge of securities and investing), not general educational credentials.
A is required: Time horizon determines the appropriate investment types based on when the client needs the funds. Short time horizons require less volatile investments; long time horizons can accommodate more volatility. B is required: Tax status affects the suitability of tax-advantaged investments like municipal bonds, tax-deferred accounts, and tax-loss harvesting strategies. D is required: Liquidity needs determine how much of the portfolio must remain accessible for emergency funds, planned large purchases, or ongoing income needs.
The Series 65 exam tests precise knowledge of the client profile factors FINRA Rule 2111 names for suitability. Understanding that investment experience (not educational background), liquidity needs (not total assets), and tax status (not employment) are the specific required factors prevents both over-collection and under-collection of client information.
A registered investment adviser has gathered complete Know Your Customer information from four clients. Which of the following scenarios indicate that KYC information should be updated?
1. A client turns 59ยฝ years old and can now access IRA funds without penalty
2. A client receives a $2 million inheritance from a deceased parent
3. A client's risk tolerance changes from aggressive to risk-averse after experiencing a 30% portfolio decline
4. A client's account value rises 2% over a quarter with no change in income, objectives, or plans
A is correct. Only statements 2 and 3 represent material changes requiring KYC updates.
Statement 1 is false: While turning 59ยฝ affects penalty-free IRA access, this does not necessarily represent a material change in the client's financial situation, investment objectives, or time horizon unless the client's circumstances or goals change. Age alone reaching a regulatory threshold does not automatically trigger KYC updates if the client's profile remains unchanged.
Statement 2 is true: A $2 million inheritance materially changes the client's financial situation (net worth and assets available for investment), which may affect suitable asset allocation, risk capacity, and investment objectives. The adviser must update KYC to reflect this significant change and reassess suitability.
Statement 3 is true: A change in risk tolerance from aggressive to risk-averse is a material change in a core suitability factor. Risk tolerance directly determines appropriate investment types and portfolio volatility levels. The adviser must update KYC and adjust recommendations accordingly.
Statement 4 is false: An ordinary change in account value, with no change in the client's income, objectives, plans, or other profile factors, is not a material change in circumstances and does not call for a KYC update.
The Series 65 exam tests understanding that Know Your Customer is an ongoing obligation requiring updates when client circumstances materially change. Changes affecting financial situation, investment objectives, tax status, time horizon, liquidity needs, investment experience, or risk tolerance require KYC updates and suitability reassessment. Advisers must distinguish between routine account fluctuations and material changes requiring complete review.
