(28)A suitable definition of extreme but plausible market conditions is a core component of CCP risk management. For the purposes of keeping the CCP risk management framework up to date, extreme but plausible market conditions should not be considered as a static concept, but rather as conditions that evolve over time and vary across markets. One market scenario can be extreme but plausible for one CCP while not having great importance for another. A CCP should establish a robust internal policy framework for identifying the markets to which it is exposed and employ a common minimum set of standards for defining extreme but plausible conditions in each identified market. It should also consider objectively the potential for simultaneous pressures in multiple markets.
