How a clearing broker carries accounts and handles post-trade obligations, including its relationship with introducing firms, clients, and clearinghouses.
A clearing broker is a broker-dealer or derivatives intermediary that provides account-carrying and post-trade services for its own customers, introducing firms, or other market participants. Depending on the market and agreement, it may maintain books and records, safeguard customer assets, calculate margin, reconcile trades, and meet obligations through a clearinghouse or another clearing provider.

The introducing firm may own the customer relationship and accept orders while the carrying firm maintains the account and performs specified post-trade functions. In a fully disclosed arrangement, the carrying firm generally knows the underlying customer’s identity. In an omnibus arrangement, the intermediary can hold a combined account, subject to the applicable agreement and rules.
The legal allocation matters more than the marketing label. FINRA Rule 4311 requires covered carrying agreements to allocate responsibilities and requires customer notice in specified fully disclosed arrangements. It also assigns safeguarding of customer funds and securities and preparation of account statements to the carrying firm, subject to the rule’s terms.
| Service | Typical clearing or carrying role | What to verify |
|---|---|---|
| Trade comparison and reconciliation | Matches account records to executions and clearing records | Exception handling and cutoff times |
| Books and records | Maintains customer positions, cash balances, and transaction history | Which legal entity is the official account carrier |
| Margin and credit | Calculates requirements and monitors deficits | House requirements, liquidation rights, and intraday calls |
| Safekeeping | Holds or controls customer funds and securities under applicable rules | Custody location, segregation, and account title |
| Clearing submission | Sends eligible transactions to a clearing agency or clearing member | Relevant membership and service scope |
| Settlement | Coordinates delivery and payment through depositories, banks, and other systems | Settlement agent, failed-trade process, and finality |
| Confirmations and statements | Produces customer transaction and account records | Responsible firm and correction procedures |
| Corporate actions and tax records | Processes distributions, reorganizations, and reporting | Deadlines, elections, withholding, and jurisdiction |
The clearing broker does not necessarily operate the depository, payment system, or CCP. It connects account-level obligations to those infrastructures.
| Role | Primary function | Usually carries customer assets and positions? | Direct CCP membership required? |
|---|---|---|---|
| Clearing or carrying broker | Account maintenance and post-trade processing | Often | No, not for every arrangement |
| Introducing broker | Customer relationship and order introduction | Usually no | No |
| Executing broker | Routes or executes transactions | Not necessarily | No |
| Prime broker | Bundles financing, custody, execution support, reporting, and other institutional services | Often | Depends on service and entity |
| Clearing Member | Meets direct clearinghouse obligations | May clear proprietary or client positions | Yes, for the relevant clearing service |
| Futures Commission Merchant | Accepts covered derivatives orders and customer funds or assets | Yes when carrying customers | Only if directly clearing at the relevant DCO |
One company group may use different subsidiaries for securities, futures, swaps, custody, and banking services. Verify the legal entity on the account agreement and statement.
A customer places an order through Introducing Firm I to buy 100 shares at $30, for a gross trade value of $3,000. Firm I transmits the order to an executing venue. Carrying Broker B maintains the customer’s account under a fully disclosed carrying agreement.
After execution:
100 shares and a $3,000 purchase obligation to the customer account.The customer sees one purchase, but Broker B may settle only a net position across many transactions. If the trade fails to settle, the customer record, clearing obligation, and depository status must be reconciled; the original execution does not disappear merely because settlement is delayed.
In U.S. securities markets, a FINRA member can introduce customer accounts to a carrying firm under an approved carrying agreement. The agreement allocates responsibilities, and the carrying firm performs specified custody, recordkeeping, statement, credit, and settlement functions.
In U.S. futures and options on futures, an FCM can accept customer orders and money or assets supporting those orders. An FCM that is a member of the relevant derivatives clearing organization can clear directly; another FCM may use a clearing arrangement. The terms “clearing broker” and “FCM” should not be treated as universal synonyms because their legal scope differs.
A carrying arrangement does not eliminate trade, market, settlement, or counterparty risk. It allocates functions among firms and infrastructures.

For an institutional relationship, also assess service-level commitments, concentration, collateral mobility, intraday liquidity, business continuity, cyber controls, and the ability to transfer positions to another provider.
