The French Financial Markets Authority has appointed Christophe Bonnet as director of data and supervision, placing the current deputy director and head of data policy in charge of the unit responsible for market surveillance and the authority’s wider use of data science. He succeeds Alexandra Givry, who is preparing to leave the AMF after 17 years focused on market surveillance and the authority’s transformation. Bonnet joined the AMF in 2010 and has held roles supervising investment services providers, post-trade activities and a data-led supervision team created to use regulatory data specifically for supervisory purposes. After leading the Research-Strategy unit at Agence France Trésor in 2021 and 2022, he returned to the AMF at the end of 2022, became head of data policy and was appointed deputy director of data and supervision in November 2024. The directorate sits at the center of the AMF’s market monitoring framework and uses tools including the ICY surveillance platform, based on big data and artificial intelligence technologies, to detect market anomalies and potential market abuse, analyze market trends and investor behavior, and support the rollout of data and AI across the authority.
