On 10 December 2019, the Committee on Payments and Market Infrastructures (CPMI) and the International Organization of Securities Commissions (IOSCO) published a report, Responsibility E: A compilation of authorities’ experience with cooperation.

The report describes ways in which authorities cooperate with each other in a variety of contexts, with particular emphasis on the expectations in Responsibility E of the Principles for financial market infrastructures. It includes effective practices which may inform authorities in their development of, and improvements to, cooperative arrangements for all financial market infrastructure types. Whilst not setting out any additional standards, the report identifies a range of issues and practices that authorities have experienced and considered when determining whether, and how, to establish and enhance cooperation that suits their needs and fulfils their respective mandates.
