Swiss stock exchange operator SIX has appointed Bjørn Sibbern as CEO, effective January 1, 2025, following the departure of Jos Dijsselhof after seven years. Sibbern, who has extensive experience in capital markets and previously led SIX’s international exchange business, will ensure a smooth transition until the end of February. Under Dijsselhof, SIX underwent significant strategic transformation, including the sale of its card business and the acquisition of the Spanish stock exchange BME.
