At SIX, which operates the infrastructure for the Swiss financial center, significant departures will occur on very short notice—or, more bluntly, with a bang. Group Executive Board members Javier Hernani, Head Business Unit Securities Services, and Jochen Dürr, Chief Risk Officer, will leave SIX on February 1, 2025, according to a press release issued on Wednesday morning.

Hernani was CEO of the Spanish stock exchange BME for many years until November 2024 and has headed the Securities Services business unit (Post Trading) since the takeover of BME by SIX. In this role, he successfully expanded the international post-trading business in particular and developed the unit into one of the most important commercial pillars of SIX.

Interim Succession Plan

José Manuel Ortiz, former Head of Clearing and Repo Operations at SIX, will manage the business unit on an interim basis until a successor has been found.

Dürr led the risk and security organization of SIX for ten years as Chief Risk Officer. Dürr also led the transformation program as part of the company's strategic realignment in 2017. By establishing and continuously developing a professional security organization, he made a significant contribution to the stability and security of SIX.

Markus Gumpfer, currently Head of Risk Management, will lead the division as a member of the SIX Group Executive Board from February 1, 2025.

Spain Write-Off and Surprising Change of CEO

SIX’s 2020 acquisition of BME proved costly, forcing the company to write off billions, including an impairment on the Worldline investment.

There had already been a surprising change of CEO at SIX in November in 2024. CEO Jos Dijsselhof was replaced by Bjørn Sibbern , as finews.ch also reported.
