An introducing broker-dealer is a securities firm that works directly with investors — opening accounts, recommending investments, and answering day-to-day questions — while a separate clearing firm executes the trades and holds the customer’s money and securities. The split lets a smaller firm focus on advice and client service without building the back-office machinery a clearing operation requires, and it puts two regulated entities behind every account instead of one.
What an Introducing Broker Actually Does
The introducing broker owns the client relationship. Staff find investors, assess their goals and risk tolerance, recommend securities, explain market conditions, and walk clients through decisions. For most investors, the introducing broker is the voice on the phone and the name on the business card.
What the firm does not do is just as defining. FINRA’s rules describe an introducing broker as a firm that is a party to a securities transaction but does not execute or clear trades.1FINRA. FINRA Rule 7210B – Definitions When a client places an order, the introducing broker passes it to a clearing firm, which carries out the trade. The introducing broker does not move money or securities between parties and, in most arrangements, does not take custody of client assets at all.
How the Introducing Broker and Clearing Firm Split the Work
The two firms operate under a written carrying agreement. FINRA Rule 4311 requires that agreement to state exactly which party handles which task, from trade execution and recordkeeping to account statements and complaint handling.2FINRA. FINRA Rule 4311 – Carrying Agreements The clearing firm settles transactions, holds client assets, and sends account statements. The introducing broker builds the client base, takes orders, and provides ongoing guidance.
Carrying agreements generally follow one of two patterns:
- Fully disclosed. The clearing firm knows the identity of every client and maintains a separate account for each one. Clients receive statements directly from the clearing firm.
- Omnibus. All client assets are pooled into a single account held under the introducing broker’s name. The clearing firm sees only the combined trading volume, and the introducing broker tracks each client’s positions internally.
The fully disclosed model is more common because it gives investors direct visibility into how their assets are held and simplifies regulatory oversight. An omnibus arrangement shifts more of the recordkeeping burden onto the introducing broker.
How Introducing Brokers Get Paid
Revenue comes primarily from commissions and markups on client transactions. In an agency trade, where the broker acts as a go-between, the firm charges a commission. In a principal trade, where the broker sells a security from its own inventory, compensation comes from the markup or markdown against the prevailing market price.
Firms may also earn per-trade ticket charges, account maintenance fees, or markups on margin interest. The carrying agreement dictates how transaction revenue is split with the clearing firm. Clearing firms typically retain interest income on client debit balances and may offset amounts the introducing broker owes against commissions due to it.
Registration and Licensing
Any broker or dealer using interstate commerce to effect securities transactions must register with the SEC under Section 15(a) of the Securities Exchange Act of 1934.3Office of the Law Revision Counsel. 15 USC 78o – Registration and Regulation of Brokers and Dealers That obligation applies to introducing brokers the same as it does to every other broker-dealer. Firms must also join FINRA — the primary self-regulatory organization for broker-dealers — by filing an application that undergoes review of the firm’s business plan, ownership, and compliance systems.4FINRA.

Individual employees who work with clients or supervise trading have to pass FINRA qualification exams. The path starts with the Securities Industry Essentials (SIE) exam, a 75-question test with a $100 fee that covers foundational industry knowledge.5FINRA. Securities Industry Essentials (SIE) Exam Passing the SIE is a prerequisite; a role-specific “top-off” exam follows. The most common is the Series 7, a 125-question test that costs $395, runs three hours and 45 minutes, and requires a passing score of 72.6FINRA. Series 7 – General Securities Representative Exam Supervisors and managers add the Series 24, a 150-question exam with a $235 fee.7FINRA. Qualification Exams
Every registered representative files a Form U4 through FINRA, which collects employment history, disciplinary records, and personal background information. Affirmative answers to disclosure questions — past criminal charges, regulatory actions, customer complaints, bankruptcies — trigger detailed disclosure reporting pages.8FINRA. Form U4 You can check a specific broker’s registration and disclosure history on FINRA’s BrokerCheck.
The Standard of Conduct for Recommendations
Since June 30, 2020, broker-dealers — introducing brokers included — must comply with Regulation Best Interest whenever they recommend a securities transaction or investment strategy to a retail customer. Reg BI requires the broker to act in the customer’s best interest at the time of the recommendation and prohibits placing the firm’s financial interests ahead of the customer’s.9eCFR. 17 CFR 240.15l-1 – Regulation Best Interest Compliance rests on four separate obligations:
- Disclosure. Before or at the time of a recommendation, the firm must give the customer a written statement covering the scope of the relationship, material fees, and conflicts of interest.
- Care. The firm must exercise reasonable diligence, care, and skill to ensure the recommendation fits the customer’s investment profile and that a series of recommended transactions is not excessive.
- Conflict of interest. The firm must establish and enforce written policies to identify, disclose, and mitigate conflicts that could push representatives to put their interests ahead of the customer’s.
- Compliance. The firm must maintain written policies and procedures reasonably designed to achieve compliance with the other three obligations.
Failing any one of these is a Reg BI violation.10U.S. Securities and Exchange Commission. Frequently Asked Questions on Regulation Best Interest
Alongside Reg BI, broker-dealers must deliver Form CRS (Customer Relationship Summary) to every retail investor before or at the time of making a recommendation, placing an order, or opening an account, whichever comes first. The document describes the firm’s services, fees and costs, conflicts of interest, and standard of conduct.11U.S. Securities and Exchange Commission. Form CRS It’s designed to be short enough to compare firms side by side.
How This Differs From a Registered Investment Adviser
An introducing broker-dealer is regulated under the Securities Exchange Act of 1934 and, when recommending, must meet Reg BI’s best-interest standard at the point of the recommendation. A registered investment adviser is regulated under the Investment Advisers Act of 1940 and owes clients a fiduciary duty at all times, meaning continuous best-interest conduct, undivided loyalty, and active avoidance or full disclosure of all conflicts throughout the relationship.
Compensation typically differs as well. Introducing brokers earn commissions per transaction. RIAs more often charge a flat annual fee, an hourly rate, or a percentage of assets under management. Some firms are dually registered, so it’s worth confirming a firm’s status on FINRA’s BrokerCheck or the SEC’s Investment Adviser Public Disclosure database.
Capital, Records, and Anti-Money-Laundering Rules
The SEC’s Net Capital Rule (Rule 15c3-1) sets a floor on liquid assets. An introducing broker that does not receive or hold customer funds or securities must maintain at least $5,000 in net capital. If the firm receives customer funds — even accepting checks made out to the firm — the minimum jumps to $250,000, the same threshold that applies to firms carrying customer accounts.12FINRA. SEA Rule 15c3-1 and Related Interpretations A firm that falls below its threshold must notify the SEC immediately and may be forced to stop doing business until the shortfall is fixed.
SEC Rules 17a-3 and 17a-4 require broker-dealers to create and preserve detailed records of transactions, communications, and customer accounts. Retention periods range from three to six years depending on the record type, with the first two years kept in an easily accessible location for regulatory inspections. Firms also file annual financial reports with the SEC under Rule 17a-5.13eCFR. 17 CFR 240.17a-5 – Reports To Be Made by Certain Brokers and Dealers
Every broker-dealer must maintain a written anti-money laundering program approved by senior management, with internal controls, independent testing, a designated AML compliance officer, and ongoing training. Firms must verify customer identities and maintain risk-based procedures for ongoing due diligence. A Suspicious Activity Report goes to FinCEN when a transaction involves $5,000 or more and the firm knows or suspects it may involve illegal funds, is designed to evade reporting requirements, has no apparent business purpose, or involves criminal activity.14eCFR. 31 CFR Part 1023 – Rules for Brokers or Dealers in Securities
What Protects Your Assets
Because the clearing firm — not the introducing broker — holds your money and securities, the Securities Investor Protection Corporation kicks in at the clearing firm level if that firm fails. SIPC coverage protects up to $500,000 per customer, with a $250,000 sub-limit for cash.15SIPC. What SIPC Protects SIPC replaces missing securities and cash when possible, but it does not protect against declines in market value, and it does not cover commodities, futures contracts, or fixed annuity contracts.
The carrying model matters here. Under a fully disclosed arrangement, the clearing firm’s separate records for each client make it easier to identify and return individual holdings during a liquidation. Under an omnibus arrangement, the introducing broker’s own records become critical to establishing each client’s claim.
Two other backstops apply at the introducing broker itself. FINRA Rule 4360 requires every member firm to carry a fidelity bond covering losses from dishonest acts of its employees; for firms with a net capital requirement below $250,000, minimum coverage is the greater of 120 percent of required net capital or $100,000.16FINRA. FINRA Rule 4360 – Fidelity Bonds FINRA Rule 4370 requires each firm to maintain and annually review a business continuity plan describing how it will keep operating through disruptions and how customers will get prompt access to funds and securities if the firm cannot continue.17FINRA. Business Continuity Planning FAQ SIPC membership alone doesn’t satisfy that plan.
