The UK's Financial Conduct Authority (FCA) is investigating allegations that former Credit Suisse employees shared confidential information via WhatsApp, particularly within its London research unit from mid-2022 to early 2023. The inquiry, which began in February 2023, focuses on potential breaches of regulatory requirements regarding the use of personal devices for business communications. UBS, which acquired Credit Suisse, stated it is unaware of the ongoing investigation, while the FCA may impose fines or other penalties if sufficient evidence is found.
