Risk management

Risk Management Stucture

The Risk Management philosophy when trading Safex Derivatives is very simple - "You stand good for your client".

What this means is that each member will carry its client's losses if the client defaults just as each clearing member will carry its member's (for whom it clears) losses if the member defaults. This pyramid structure forms the basis of the Safex Risk Management Structure.

Risk management structure

The risk that Safex therefore bears is the risk that one of the clearing members could possibly go into default, whether it is as a result of a member causing it to default or as a result of its own doings. The clearing members of Safex are all the major banking institutions hence the risk of default by one of them is very limited indeed.

This puts the onus of proper risk management squarely onto the shoulders of the clearing members who in turn pass this responsibility onto the members for whom they clear.

Notwithstanding what is said in the previous paragraphs, Safex does, however ,require a deposit to be paid by all participants in the market when they take on position. This margin is in reality a "good faith" deposit on the position that is registered in the name of a person or member. It is by no means the full purchase price of any contract, in fact only between 5% - 8%, hence the risk that is associated when trading in this market.

This good- faith deposit, or initial margin as it is referred to, is reassessed everyday by the Risk Manager at Safex on the basis as described in the next document, namely "The Margining Methodology". This document will give you an idea of how the initial margin requirements are calculated and the reasoning behind it.
