A CCP’s stress tests shall apply stressed parameters, assumptions, and scenarios to the models used for the estimation of risk exposures to make sure its financial resources are sufficient to cover those exposures under extreme but plausible market conditions.

A CCP’s stress testing programme shall require the CCP to conduct a range of stress tests on a regular basis that shall consider the CCP’s product mix and all elements of its models and their methodologies and its liquidity risk management framework.

A CCP’s stress testing programme shall prescribe that stress tests are performed, using defined stress testing scenarios, on both past and hypothetical extreme but plausible market conditions in accordance with Chapter VII. Past conditions to be used shall be reviewed and adjusted, where appropriate. A CCP shall also consider other forms of appropriate stress testing scenarios including, but not limited to, the technical or financial failure of its settlement banks, nostro agents, custodian banks, liquidity providers, or interoperable CCPs.

A CCP shall have the capacity to adapt its stress tests quickly to incorporate new or emerging risks.

A CCP shall consider the potential losses arising from the default of a client, where known, which clears through multiple clearing members.

A CCP shall periodically report its stress testing results and analysis in a form that does not breach confidentiality to the risk committee in order to seek its advice in the review of its models, its methodologies and its liquidity risk management framework.

Stress testing results and analysis shall be made available to all clearing members and, where known to the CCP, clients. For all other clients, back testing results and analysis shall be made available by the relevant clearing members on request. Such information shall be aggregated in a form that does not breach confidentiality and clearing members and clients shall only have access to detailed stress testing results and analysis for their own portfolios.

A CCP shall define the procedures to detail the actions it could take given the results of stress testing analysis.
