An introducing broker-dealer is a securities firm that works directly with investors, opening accounts and recommending investments, but does not execute trades or hold customer funds itself. Instead, it partners with a clearing firm that carries out transactions, settles them, and holds client assets in custody. The arrangement lets a smaller firm focus on client service without building the back-office machinery a clearing operation demands.
What an Introducing Broker Actually Does
The introducing broker owns the client relationship. Its representatives find investors, take stock of their financial goals and risk tolerance, recommend suitable securities, and answer the day-to-day questions that come up as markets move. When a client decides to buy or sell, the introducing broker takes the order and passes it to the clearing firm for execution.
What the introducing broker never does is handle client money or securities directly. FINRA defines an introducing broker as a firm that is a party to a securities transaction but does not execute or clear those trades.1FINRA. FINRA Rule 7210B – Definitions Cash, stock certificates, and settlement mechanics stay with the clearing firm.
How the Split With the Clearing Firm Works
Every introducing broker operates under a written carrying agreement with a clearing firm. FINRA Rule 4311 requires the two firms to spell out exactly which party is responsible for each function, including trade execution, recordkeeping, issuing account statements, and forwarding customer complaints.2FINRA. FINRA Rule 4311 – Carrying Agreements The clearing firm settles transactions, keeps custody of assets, and sends statements to investors. The introducing broker handles the advisory side.
Carrying agreements usually take one of two forms:
- Fully disclosed. The clearing firm knows the identity of every individual client and maintains a separate account for each one. Clients receive statements directly from the clearing firm, which adds a layer of independent recordkeeping.
- Omnibus. All client assets sit in a single pooled account held under the introducing broker’s name. The clearing firm sees only combined trading volume, and the introducing broker is responsible for tracking each client’s positions internally.
The fully disclosed model is more common because it gives investors direct visibility into how their assets are held. An omnibus setup places more of the recordkeeping burden on the introducing broker.
How Introducing Brokers Make Money
Revenue comes mostly from commissions and markups on the transactions the firm facilitates. In an agency transaction, where the broker acts as a go-between, the firm charges a commission or service charge. In a principal transaction, where the firm sells a security it holds in inventory, compensation comes from the markup or markdown against the prevailing market price.
Beyond per-trade fees, an introducing broker may earn flat ticket charges, account maintenance fees, or markups on margin interest. The carrying agreement dictates how transaction revenue is split between the introducing broker and its clearing partner. Clearing firms typically keep interest income on client debit balances and may offset amounts the introducing broker owes against commissions due.
Registration and Standards of Conduct
Section 15(a) of the Securities Exchange Act of 1934 requires any broker or dealer using interstate commerce to effect securities transactions to register with the Securities and Exchange Commission.3Office of the Law Revision Counsel. 15 USC 78o – Registration and Regulation of Brokers and Dealers That applies to introducing brokers the same way it applies to every other broker-dealer. Firms also have to become members of FINRA, the primary self-regulatory organization for broker-dealers, through an application process that reviews the firm’s business plan, ownership, and compliance systems.4FINRA. Register a New Broker-Dealer Firm Individual representatives who work with clients have to pass FINRA qualification exams before they can do so.
Regulation Best Interest
Since June 30, 2020, any broker-dealer recommending a securities transaction or investment strategy to a retail customer has had to comply with Regulation Best Interest. Reg BI requires the firm to act in the customer’s best interest at the time the recommendation is made and prohibits placing the firm’s financial interest ahead of the customer’s.5eCFR. 17 CFR 240.15l-1 – Regulation Best Interest Compliance rests on four obligations:
- Disclosure. Before or at the time of a recommendation, the firm gives the customer a written statement covering the scope of the relationship, material fees, and any conflicts of interest tied to the recommendation.
- Care. The firm exercises reasonable diligence and skill to make sure the recommendation fits the customer’s investment profile, and that any series of recommendations is not excessive.
- Conflict of interest. The firm has written policies to identify, disclose, and mitigate conflicts that could push representatives to favor their own interests.
- Compliance. The firm maintains written policies and procedures reasonably designed to achieve compliance with the three obligations above.
A failure on any one of the four is a violation of Reg BI.6U.S. Securities and Exchange Commission. Frequently Asked Questions on Regulation Best Interest
Alongside Reg BI, broker-dealers must deliver a 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 short document describes the firm’s services, fees and costs, conflicts of interest, and the standard of conduct that applies.7U.S. Securities and Exchange Commission. Form CRS The idea is to give investors a snapshot they can use to compare firms.
Introducing Brokers Are Not Registered Investment Advisers
Investors sometimes lump introducing brokers together with registered investment advisers, but the two operate under different legal frameworks. An introducing broker-dealer is regulated under the Securities Exchange Act of 1934, and Reg BI’s best-interest standard attaches at the moment a recommendation is made. It does not create a continuous, ongoing duty.
A registered investment adviser, by contrast, is regulated under the Investment Advisers Act of 1940 and owes clients a fiduciary duty at all times. That duty requires continuous loyalty and active avoidance or full disclosure of conflicts throughout the relationship, not only at the point of a specific recommendation.
Compensation models line up with those roles. Introducing brokers typically earn commissions per transaction, which can create an incentive toward more frequent trading. Advisers more commonly charge a flat annual fee, an hourly rate, or a percentage of assets under management. Some firms are dually registered, so checking a firm’s status on FINRA’s BrokerCheck or the SEC’s Investment Adviser Public Disclosure database is worthwhile before signing anything.
What Protects a Client’s Assets
Net Capital
The SEC’s Net Capital Rule (Rule 15c3-1) requires every broker-dealer to maintain a minimum cushion of liquid assets. For an introducing broker that does not receive or hold customer funds or securities, the minimum is $5,000. If the firm receives customer funds, even something as basic as accepting checks made payable to the firm, the minimum jumps to $250,000, the same threshold that applies to firms carrying customer accounts.8FINRA. SEA Rule 15c3-1 and Related Interpretations A firm that drops below its required net capital has to notify the SEC immediately and may have to stop doing business until the shortfall is fixed.
Fidelity Bond
FINRA Rule 4360 requires every member firm to carry a fidelity bond covering losses caused by dishonest acts of its employees. For firms with a net capital requirement below $250,000, which covers most introducing brokers, minimum coverage is the greater of 120 percent of the firm’s required net capital or $100,000.9FINRA. FINRA Rule 4360 – Fidelity Bonds
SIPC Coverage
Because an introducing broker does not hold your assets, Securities Investor Protection Corporation coverage attaches at the clearing firm. If the clearing firm fails, SIPC protects up to $500,000 per customer, with a $250,000 sublimit for cash.10SIPC. What SIPC Protects The protection replaces missing securities and cash where possible. It does not cover market losses, and it does not extend to commodities, futures contracts, or fixed annuity contracts.
This is where the fully disclosed carrying arrangement pays off in practice. Because the clearing firm keeps separate records for each client, identifying and returning individual holdings during a liquidation is more straightforward. In an omnibus arrangement, the introducing broker’s own records become critical to establishing each client’s claim.
