Prisma: Update of ETD Liquidity Add-On Parameters effective 20 October 2025

Eurex Clearing Circular 080/25 Prisma: Update of ETD Liquidity Add-On Parameters effective 20 October 2025

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 and Liquidity Factors across all Prisma Liquidation Groups in the ETD space. The recalibration follows standard calibration methodology. 

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 a 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, Liquidity Add-On is designed to capture the potential additional costs when liquidating large and concentrated portfolios.

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 underlying cash market liquidity pools.

The recalibration of the Liquidity Factors was conducted with the input received from Liquidity Surveys that were carried out separately for each Asset Class.

All Prisma ETD Liquidation Groups will be affected.

Unless the context requires otherwise, terms used and not otherwise defined in this circular shall have the meaning ascribed to them in the Clearing Conditions or FCM Clearing Conditions of Eurex Clearing AG, as applicable.
