Overview

The Government Securities Clearing Corporation (GSCC) centralized clearance and settlement services for the U.S. government securities market. Its core purpose was to improve operational efficiency, reduce settlement risk, and preserve market liquidity by standardizing trade comparison, netting and settlement procedures.

Core functions

• Trade comparison and matching — automated reporting, validation, and matching of buy/sell trade data.
• Netting — multilateral netting of participants’ positions to reduce the number and size of payments required at settlement.
• Central counterparty role — acting as the counterparty to both sides of a matched trade to allocate settlement obligations and reduce bilateral counterparty risk.
• Risk management — processes to monitor and manage credit and settlement exposures and to support market integrity.

Securities processed

The GSCC cleared transactions in:
* Treasury bills, notes and bonds
Zero‑coupon securities
Government agency securities
* Inflation‑indexed securities

At its peak, the GSCC cleared roughly $1.6 trillion in government‑securities trades per day (through 2002).

Settlement

Final net settlement obligations were settled via the Fedwire Securities Service through each participant’s settlement bank. This integration with Fedwire ensured timely transfer of securities and funds required to complete net settlements.

History

The GSCC was formed in 1986 in response to concerns from primary dealers and the Federal Reserve about the risks and inefficiencies of bilateral, paper‑based trade confirmation and settlement. Its board included representatives from primary dealers and clearing banks, the GSCC president, and NSCC‑designated directors.

Merger and legacy: FICC

In 2003 the GSCC merged with the Mortgage‑Backed Securities Clearing Corporation (MBSCC) to form the Fixed Income Clearing Corporation (FICC), a subsidiary of the Depository Trust & Clearing Corporation (DTCC). FICC retained the GSCC’s services within a two‑division structure:

• Government Securities Division (GSD) — continues real‑time matching, clearing, netting and risk management for Treasury and other government issues.
• Mortgage‑Backed Securities Division (MBSD) — provides trade matching, confirmation, netting, electronic pool notification and risk management for mortgage‑backed securities markets (participants include mortgage lenders, government‑sponsored enterprises, banks and other institutions).

Each division operates with its own collateral margin pool but continues the GSCC’s objective of reducing settlement risk and improving operational efficiency in fixed‑income markets.

Importance

By centralizing trade comparison and acting as the settlement counterparty, the GSCC materially reduced bilateral counterparty risk and contributed to the liquidity and integrity of the U.S. government securities market. Its functions and structure persist today through the FICC.
