NSCC’s Trade Guarantee

Market risk management is the foundation supporting NSCC’s trade guarantee to members.

As central counterparty, NSCC:

  • serves as buyer for every seller, and seller for every buyer, for settlement purposes.
  • ensures completion of trades if one of the trading partners defaults.
  • through multilateral netting, significantly reduces (i) security movements, (ii) value of trade obligations requiring settlement, and (iii) capital requirements.

Equity Risk Team

The Equity Risk team monitors risks presented to NSCC by its clearing members.

Monitoring takes a variety of forms, including:

  • start of day and intraday (15 minute) Clearing Fund assessment and collection.
  • daily margin and collateral backtesting and stress testing.
  • market and portfolio risk monitoring; including intraday exposure and projected liquidity sufficiency.

NSCC’s Clearing Fund

NSCC’s Clearing Fund provides a liquidity and loss resource in the event of a member default. Clearing Fund Requirements are calculated and collected daily based on each member’s net unsettled positions.

Some key components of the Clearing Fund Requirement include:

  • volatility charge – which is either a model-based VaR charge or a haircut-based charge depending on asset type and liquidity profile.
  • margin requirement differential – which mitigates the risks from day-over-day fluctuations in a member’s portfolio.
  • mark-to-market – which is the difference between the contract price and the current market price.
