Swiss Banking Scandal: Credit Suisse's Illegal Surveillance of Departing Executive

In the summer of 2019, Switzerland's second-largest bank embarked on an extraordinary campaign that would culminate in one of the country's most significant corporate governance scandals. Credit Suisse, based in Zurich, had authorized a covert surveillance operation targeting one of its own senior executives—Iqbal Khan—following his departure to rival UBS.

Khan, who served as Credit Suisse's global head of wealth management, announced his move to UBS in July 2019. The move itself was not unusual in competitive banking circles; executive poaching between rival institutions is common practice. What followed was not.

Within days, Credit Suisse's operations chief, Pierre-Olivier Bouée, authorized a private investigation firm to conduct intensive surveillance on Khan. Between July and September 2019, private detectives tracked Khan's movements throughout Zurich—monitoring not only his solo activities but also following him and his wife together. The operation was both extensive and systematic, representing the kind of invasive monitoring typically associated with espionage rather than corporate human resources management.

The surveillance continued until September 2019, when Khan himself confronted one of the private investigators following him through the streets of Zurich. The encounter was a turning point: what had been a hidden operation suddenly became visible, and word began spreading through Zurich's tight financial community.

Bouée, who had authorized the surveillance without obtaining broader approval from Credit Suisse's board or senior management, resigned on October 1, 2019—just weeks after the confrontation. The bank's global head of security departed around the same time. More tragically, the private detective who had organized the surveillance operation died by suicide in October 2019, adding a darker dimension to an already troubling story.
