The European Securities and Markets Authority has published newly developed Principles on third-party risks supervision, intended to support a common and effective EU-wide supervisory culture. The 14 principles respond to growing risks in supervised firms’ use of outsourcing, delegation and other third-party services. They are designed to provide a common supervisory basis for National Competent Authorities and ESMA, strengthen supervisory frameworks, and help supervised entities better understand and manage third-party risks. ESMA will support progressive implementation through supervisory discussions and case studies among National Competent Authorities.
