Clearing:
- The process through which derivatives trades are confirmed and registered
Clearing House:
- Central Counterparty (CCP)
- Greatly reduces counterparty risk (credit risk) - BUT NOT ELIMINATES
- Guarantees the performance of a contract - FOR ITS MEMBERS ONLY
- Gives a high degree of confidence in the system
- Clearing house as registrar
- Most derivatives exchanges have their own clearing house
The Structure of the clearing system:
- Novation (Where the Clearing House becomes the seller to the buyer and the buyer to the seller)
- They are principals, not agents

- T.R.S. = Trade Registration System
NCM would need to give up to a GCM for the trade to be novated
Guarantee (Protection given to counterparties should default occur):
- Mutual Guarantee (Default 'waterfall')
- Take defaulting member's margin
- Defaulting member's contributions to the default fund
- Other members' contributions to default fund
- Clearing house's own funds
- Remember this list and order
Margin Account Types and Key Features:
- House Account:
- Used for proprietary trades by the firm
- Trades are for the firm's benefit or loss, excluding client positions
- Margin payments are managed internally, with exposure fully borne by the firm
- Client Segregated Accounts:
- Separate accounts for individual client trades
- Required by most exchanges and regulators
- Client assets are protected from the firm's liabilities
- Initial and variation margin are calculated and collected per client, ensuring their funds are protected
- Client Non-Segregated Accounts:
- Combines multiple client trades into a single account
- Higher risk for clients in case of firm default
- Potential cash flow benefits for clearing firms
- Margin offsets across clients' positions can reduce overall margin requirements, but increase risk exposure for individual clients
Initial Margin: Futures and Options on Futures
- SPAN (Standard Portfolio Analysis of Risk)
- Collects all the derivative positions of a clearing member into portfolios and calculates the risk of each portfolio
- Calculates the most probable ONE DAY LOSS
- SPOT-Month Charge
- Used to reflect increased risk with contracts close to expiry
- An adjustment
Variation Margin: Futures and Options on Futures
- Collected through Protected Payment Systems (PPS)
- An adjustment for any P/L on Position
- Done on a day-to-day basis
- Cash
Maintenance Margin:
- Variation Margin is paid out of the initial margin held at the clearing house
- Margin calls are made when initial margin falls below a pre-determined level
- NOT used in UK by clearing houses, although brokers tend to use this method with their clients
