This ESRB Occasional Paper complements the publication of indicators on central counterparties (CCPs) in the ESRB's Risk Dashboard as part of its monitoring framework. It provides a methodological background to the development of the individual measures and discusses different aspects that should be considered when designing a monitoring framework for CCPs. The paper also highlights a number of areas in which more granular data are required in order, for example, to monitor the interconnectedness of CCPs within the broader financial system. CCPs play a key role in financial markets, as they reduce counterparty credit risk. This role is now heightened following post-crisis reforms of the over-the-counter (OTC) derivatives markets. Since CCPs may be viewed as systemically important institutions, it is crucial to ensure that they are regulated and monitored effectively. The ESRB has, therefore, sought to strengthen the framework used to analyse developments at CCPs in the EU from a macroprudential perspective
