WFE responds to CPMI-IOSCO Framework for Supervisory Stress Testing of CCPs

The WFE has responded to the CPMI-IOSCO Framework for Supervisory Stress Testing of Central Counterparties (CCPs).

In response to the consultation, the WFE made a number of points:

• There are areas of concern around information sharing and issues of confidentiality, particularly for multi-jurisdictional stress testing; regulators can address these issues through engagement with their counterparts, market infrastructure operators and market participants.
• The WFE cautions against taking a one-size-fits-all stress test approach. As CPMI-IOSCO rightly recognises, not all aspects of a stress test will be relevant depending on the jurisdiction/market structure in which the CCP operates. The WFE considers it preferable to have a small suite of stress tests to reflect the diversity within the CCP ecosystem.
• The WFE believes the value of multi-jurisdictional stress tests sits at the macro-prudential level, and as such, it is encouraged by the focus on macro-prudential stress scenarios and impacts, which should supplement the more targeted stress tests performed by each CCP.
• Authorities should seek the expertise and input of CCPs when designing the stress tests to ensure their relevance and that the scenarios are indeed plausible.
