The Bank of England (BoE) has published details of its stress test of UK central counterparties (CCPs) for 2025. The exercise is designed to assess the financial resilience of UK CCPs under severe market stress. It focuses on the default of two or more clearing members—with particular emphasis on the two whose default would cause the greatest depletion of CCP resources—through a core Credit Stress Test, complemented by reverse and sensitivity testing. Although a full Liquidity Stress Test is not conducted, the exercise will include a qualitative exploration of liquidity risks. The BoE say that the test will cover all three authorised CCPs (ICE Clear Europe Limited, LCH Limited, and LME Clear Limited), use the end of day on Wednesday 26 March 2025 as the reference date, and rely on data submitted via structured templates. The results will be published in a report in Q4 2025.
