At Cboe Clear Europe our core focus is risk management. Our advanced risk platform provides a safe, transparent and robust system to manage risk and volatility even in the most extreme circumstances.
The core margin model is based on a Filtered Historical Simulation (FHS), Expected Shortfall (ES) methodology. This model estimates potential loss based on historical price changes (returns). Margin is calculated using this model represent the potential expected loss for a given portfolio based on Cboe Clear Europe’s assumed lookback period, liquidation period, and confidence level.
Article 28 of the EMIR RTS sets out requirements for CCPs to limit procyclicality of margin requirements to the extent that the soundness and financial security of the CCP is not negatively affected. To comply with regulatory requirements, Cboe Clear Europe applies an anti-procyclicality (APC) measure in the form of a stressed historical simulation (StressHS) margin which aims at reducing the procyclicality of the stand-alone FHS IM (ie. by applying the option set out under Article 28(1)(b) of the EMIR RTS). An APC-compliant margin is then computed as a weighted sum of the FHS and the StressHS margins.
Cboe Clear is exposed to investment risk when Clearing Participants lodge cash Collateral to Cboe Clear to cover Margin requirements and Clearing Fund Contributions.
