On 10 April 2018, the Committee on Payments and Market Infrastructures (CPMI) and the International Organization of Securities Commissions (IOSCO) published a Framework for supervisory stress testing of central counterparties. The framework provides authorities with guidance to support the design and implementation of supervisory stress tests for central counterparties (CCPs).

The supervisory stress testing framework is designed to support tests conducted by one or more authorities that examine the potential macro-level impact of a common stress test event affecting multiple CCPs. Among other things, such supervisory stress tests will help authorities better understand the scope and magnitude of the interdependencies between markets, CCPs and other entities such as participants, liquidity providers and custodians.
