Yves Baguet is quitting his roles as Deutsche Börse chief technology officer and Clearstream CIO, and will be replaced by company man Richard Green.
Baguet joined Clearstream in 1994, holding various technology-related roles before being made CIO in 2000, in charge of IT development, operations, infrastructure and sales.
Also a member of the Clearstream International executive board, he was made CTO of parent Deutsche Börse in February but has now decided to quit on "amicable terms" this month to "pursue new challenges".
Green, who joined Clearstream in 1999 from NatWest Investments, is currently head of cash infrastructure and added value applications. He will take on the role of Clearstream CIO permanently and will also act as Deutsche Börse CTO on an interim basis.
Jeffrey Tessler, CEO, Clearstream, says: "IT is at the core of what we do and we could not offer market-leading products without personalities who combine extensive IT expertise with a profound understanding of our business. I wish Yves Baguet all the best and welcome Richard Green, a longstanding Clearstream expert, in his role as our new Business CIO."
