A commodities central counterparty (CCP) assumes significant counterparty and settlement risk because it becomes the central clearing entity between market participants. The CISI UAE Financial Rules and Regulations therefore requires a commodities CCP to operate comprehensive prudential controls, including margin requirements, default funds, daily liquidity assessment and stress testing. Stress tests must assess whether margin and default-fund resources remain sufficient under severe but plausible scenarios. The CCP must also conduct periodic back tests specifically to ensure that the stress-test scenarios remain adequate . Back testing compares the assumptions and risk parameters used in the testing framework with actual historical or observed outcomes, enabling weaknesses in the stress methodology to be identified. It does not replace regular stress testing; therefore, option A is directly contrary to the rule. Default-fund contributions are based principally on clearing members' risk exposures, and the purpose of back testing is not simply to determine the fund's extreme tolerance level. The CISI material expressly identifies adequacy of stress-test scenarios as the objective. Therefore, option B is correct.
