Eurex Clearing
1. Introduction
As part of a regular review of concentration risk handling in the risk methodology, Eurex Clearing has recalibrated the Liquidity Add-on for ETD products. The affected model parameters comprise Market Capacities of all Prisma Liquidation Groups in the ETD space. The recalibration follows standard calibration methodology.
Production start: 29 November 2021
Eurex Clearing provides the possibility to calculate impacts on margining using Cloud PME, where an additional environment was set up with the updated parameters at the Cloud Prisma Margin Estimator.
2. Required action
No specific actions are required by clients. The recalibration is a regular update and does not encompass changes to the model.
3. Details of the initiative
Eurex Clearing has prudent risk framework in place to mitigate counterparty credit risks. In particular, concentration risks are covered as part of this framework. Next to Concentration Risk limits, Eurex Clearing’s PRISMA methodology comprises a dedicated Liquidity Add-On accounting for this type of risk.
In general, the Liquidity Add-On is designed to capture the potential additional costs when liquidating portfolios, where the key features are:
The Liquidity Add-On’s scaling properties towards large and potentially concentrated positions are mainly governed by a linear Liquidity Factor function, which translates position sizes into a scaling factor in the Add-On. As part of a regular review of concentration risk handling in the risk methodology, Eurex Clearing has recalibrated the Market Capacity parameters with a focus on the observable tradable volumes in the market as well as availability of broader liquidity pools, whereby accessibility to the underlying cash market allows to reflect higher liquidity for certain products.
All Prisma ETD Liquidation Groups will be affected.
