What it means
It helps to separate the two halves of a trade. Execution is finding the other side and agreeing a price, which happens in seconds, while clearing and settlement is everything afterwards: confirming the terms, netting obligations, delivering the securities against payment, and recording the position in the right account.
Those back-office functions need capital, connections to central clearing houses and custodians, and a compliance operation that few small firms can justify. The introducing broker model exists because of that cost.
A boutique wealth manager can advise clients, place orders and own the relationship, while a large clearing firm holds the assets, produces the statements, calculates margin and handles corporate actions such as dividends and rights issues. Clients often notice the arrangement only when their account statement arrives on the clearing firm's letterhead.
The commercial arrangement is a revenue split. The introducing broker charges the client a commission and pays the clearing broker a per-trade or per-ticket charge, plus fees for margin lending, custody and any additional services.
Because the clearing charge is largely fixed per transaction, the introducing broker's margin improves sharply with volume, which is why clearing agreements are renegotiated as a firm grows. The relationship carries real risk on both sides, and it is worth understanding who carries what.
The clearing broker takes on credit risk if a client fails to pay for a purchase or meet a margin call, and the introducing broker usually indemnifies it for losses on introduced accounts. Regulators also hold the clearing firm responsible for safeguarding client assets, which is why it will impose limits on the kinds of clients and instruments it will accept.
In practice
Real-world examples.
Example
A twelve-person advisory firm launches with 400 clients and no back office. It signs a clearing agreement with a large firm that provides account statements, tax reporting and custody, allowing the advisers to concentrate entirely on portfolio decisions.
Example
An online trading platform grows from 5,000 to 60,000 accounts in two years and renegotiates its clearing contract, cutting the per-trade charge by a third. The saving funds a reduction in headline commissions that the platform uses to attract further accounts.
Example
A hedge fund uses one broker for execution because of its research and a separate prime broker to clear, finance and hold the positions. Consolidating settlement in one place gives the fund a single margin calculation across all its trades rather than several fragmented ones.
Formula
Calculation
The economics of an introducing relationship come down to a per-trade margin:
Net commission to the introducing broker = number of trades x (client commission per trade - clearing charge per trade)
A mid-sized introducing broker executes about 2,000 trades a day across 250 trading days.
Annual trades = 2,000 x 250 = 500,000
It charges clients a flat $8.00 commission per trade and pays its clearing firm $2.50 per trade under the clearing agreement.
Gross commission = 500,000 x $8.00 = $4,000,000
Clearing cost = 500,000 x $2.50 = $1,250,000
Net commission retained = $4,000,000 - $1,250,000 = $2,750,000
That leaves 68.75% of gross commission with the introducing broker to cover advisers, technology and profit. If volume doubled to 1,000,000 trades and the clearing charge were renegotiated to $2.00, the retained amount would be 1,000,000 x $6.00 = $6,000,000, which shows why scale and clearing terms matter so much in this business.Case study
Seen in the real world.
Halbrook Securities is an invented firm used purely for this illustrative example. It began as a three-person execution desk serving regional asset managers and grew to handle roughly 2,000 trades a day, all cleared through a large national clearing broker at $2.50 per trade.
At that volume Halbrook was paying $1,250,000 a year in clearing charges against $4,000,000 of gross commission. The management team investigated becoming self-clearing, and the analysis was sobering: building settlement systems, hiring an operations team and meeting the regulatory capital requirement would have cost several million dollars up front and added fixed costs regardless of trading volume.
Halbrook stayed with the introducing model but used its volume to negotiate a tiered rate, a shared technology allowance and better margin lending terms. In this illustrative case the decision was purely arithmetic, and the firm concluded that clearing is a scale business it should buy rather than build until its volumes were several times larger.
Watch out
Common mistakes.
- Assuming the broker whose name is on the advice statement also holds the money. In an introducing arrangement the client's cash and securities sit with the clearing broker, which is a different regulated firm entirely.
- Confusing a clearing broker with a clearing house. The clearing house is the central market infrastructure standing between buyers and sellers, while the clearing broker is a member firm that accesses it on behalf of clients.
- Thinking clearing is only about paperwork. The clearing broker extends credit, calculates margin and can liquidate positions if a client fails to meet a call, so its risk policies directly affect what clients are allowed to do.
Questions
People also ask.
What is the difference between an executing broker and a clearing broker?
The executing broker finds the counterparty and agrees the price, while the clearing broker settles the trade and holds the resulting position, and one firm can perform both roles.
How does a clearing broker get paid?
Through per-trade or per-ticket charges, custody and account fees, interest on margin lending and cash balances, and fees for extra services such as securities lending.
Is a prime broker the same as a clearing broker?
A prime broker performs clearing and custody but adds financing, securities lending, reporting and introduction services aimed at hedge funds, so it is a broader offering built on the same foundation.
