The Fixed Income Clearing Corporation is DTCC's central counterparty for eligible U.S. government and mortgage-backed securities transactions.
The Fixed Income Clearing Corporation (FICC) is a U.S. Securities and Exchange Commission-registered clearing agency and central counterparty for eligible government securities and mortgage-backed securities transactions. It is a subsidiary of The Depository Trust & Clearing Corporation (DTCC) and operates through its Government Securities Division (GSD) and Mortgage-Backed Securities Division (MBSD).
FICC does not issue bonds, provide investment recommendations, or operate as a general exchange. Its role begins after market participants arrange eligible transactions: it compares or matches trade data, applies central-counterparty risk controls, nets obligations, and supports settlement.
| Division | Core market | Selected functions |
|---|---|---|
| Government Securities Division (GSD) | Eligible U.S. Treasury and agency securities, including cash and repo activity | Trade comparison, central-counterparty services, netting, risk management, and settlement support |
| Mortgage-Backed Securities Division (MBSD) | Eligible agency mortgage-backed securities | Trade matching, TBA netting, pool comparison and netting, risk management, and settlement support |
Eligibility, membership, service, and guarantee rules are product-specific. The fact that an instrument is a bond does not mean FICC clears it.
Older government-securities documents may refer to the Government Securities Clearing Corporation (GSCC). GSCC is not a separate current clearing corporation alongside FICC. In 2003, GSCC and the Mortgage-Backed Securities Clearing Corporation were integrated to form FICC; their principal service lines became FICC’s Government Securities Division and Mortgage-Backed Securities Division.
The predecessor name matters when reading an agreement, operational manual, or market study written before the integration. It should not be used to infer a current membership, service, or legal obligation. For current government-securities clearing questions, identify the relevant FICC GSD service and use the current FICC rules.
| Document reference | How to interpret it |
|---|---|
| GSCC in a pre-2003 source | Historical predecessor to FICC’s Government Securities Division |
| FICC GSD | Current division serving eligible government-securities and repo activity |
| FICC MBSD | Current division serving eligible agency mortgage-backed securities activity |
The historical continuity does not mean every old GSCC rule or procedure remains effective. Dates and governing documents must be checked.
The exact process differs by division and service, but the simplified sequence is:

This diagram is conceptual. The applicable FICC rulebook determines when a transaction is compared, novated, guaranteed, netted, and settled.
Members or authorized submitters send transaction data to the relevant FICC service. Comparison or matching checks whether both sides agree on key economic details such as security, quantity, price, counterparty, and settlement date. A mismatch must be resolved before the records can support reliable downstream processing.
For eligible transactions accepted into central-counterparty processing, FICC stands between the original parties. The member that sold faces FICC as buyer, and the member that bought faces FICC as seller. This standardizes counterparty exposure and gives FICC responsibility for managing the resulting obligations under its rules.
Central clearing changes the counterparty; it does not erase economic exposure. A member can still lose money when interest rates, collateral values, or market liquidity change.
FICC combines eligible offsetting obligations. Instead of delivering and receiving the same security many times across separate bilateral trades, a member can settle a smaller net position.
Netting can reduce operational volume, securities movements, cash movements, and replacement-cost exposure. Its effectiveness depends on the positions being legally and operationally eligible for the same netting set.
FICC collects required deposits based on its risk methodologies and maintains clearing-fund resources. Margin is intended to cover modeled exposure arising from a member’s portfolio and potential liquidation after a default.
Margin is not a guarantee that losses cannot exceed collected resources. Models, stress assumptions, collateral liquidity, and the speed of a default-management process all matter.
After netting, members must deliver or receive securities and cash according to the applicable settlement instructions. Settlement infrastructure completes the transfer; FICC’s clearing role should not be confused with every depository, custodian, payment, or transfer system used in the process.
Assume Dealer A completes two eligible same-day trades in the same Treasury CUSIP:
Without netting, the dealer has $170 million of gross securities movements: $100 million received and $70 million delivered. In a simplified net position:
$100 million bought - $70 million sold = $30 million net long.
The dealer would receive $30 million face value on a net basis rather than separately receiving $100 million and delivering $70 million. Corresponding cash obligations are also calculated under the clearing rules.
Actual FICC netting is multilateral and includes settlement values, accrued interest, fail positions, repo terms, member accounts, and eligibility rules. The example isolates one CUSIP only to show the basic arithmetic.
GSD supports the market where the U.S. government and agencies fund themselves and where dealers finance inventories through repos. DTCC states that GSD’s netting service produces a single net long or short position for each eligible security within the applicable account and settlement structure.
This infrastructure matters because Treasury and repo markets process large volumes and underpin collateral, liquidity, benchmark yields, and monetary-market activity. Reliable matching and net settlement reduce unnecessary movements, while central risk management addresses the exposure concentrated at the clearing house.
MBSD supports eligible agency mortgage-backed securities transactions. The forward TBA market allows participants to agree on general security characteristics before the specific mortgage pools are identified. MBSD provides matching and netting services for eligible TBA trades and supports pool-level comparison and settlement processing.
Mortgage-backed securities introduce allocation and pool-delivery details that do not arise in a plain Treasury trade. MBSD’s workflow is therefore related to, but not interchangeable with, GSD’s workflow.
| Institution or function | Primary role | What it is not |
|---|---|---|
| DTCC | Parent company for several U.S. post-trade infrastructure subsidiaries | A single clearing service |
| FICC | Central counterparty and clearing agency for eligible government and mortgage securities activity | A bond exchange or investment adviser |
| GSD | FICC division for eligible government securities and repo activity | The whole of FICC |
| MBSD | FICC division for eligible agency mortgage-backed securities activity | A mortgage lender or loan servicer |
| DTC | Securities depository, custody, and settlement infrastructure for eligible securities | FICC’s government-securities CCP service |
| Trading venue or dealer | Where prices are communicated and transactions are arranged | The post-trade central counterparty merely because it executes a trade |
The distinctions matter when tracing a failed trade or measuring exposure. Execution, clearing, custody, payment, and final settlement can involve different legal entities and systems.
SEC rule changes have expanded central-clearing requirements for certain cash Treasury and Treasury repo transactions. The affected transaction scope, exclusions, access arrangements, and compliance timetable are regulatory questions, not conclusions that should be inferred from a product label alone.
Market participants should check the SEC’s current Treasury-clearing guidance and FICC’s current rules before making a compliance determination. Requirements and implementation details can change.
Central clearing replaces many bilateral relationships with a shared dependency on the clearing agency. Strong governance, recovery planning, liquidity resources, and operational resilience are therefore critical.
When volatility rises, margin requirements can increase. A member may need cash or eligible collateral quickly even when its long-term position remains economically sound.
Margin and stress frameworks depend on data, assumptions, liquidation periods, correlations, and scenario design. No model captures every possible market condition.
Submission errors, mismatched trades, connectivity problems, cyber incidents, or settlement-system outages can delay processing. Centralization can improve control while also making resilience at key nodes more important.
A firm cannot assume that every fixed-income trade is eligible for FICC. Product, counterparty, membership, account, and transaction requirements must be checked.
