The Belgium Financial Services and Markets Authority (FSMA) published a newsletter setting out that, from 15 July 2026, the banker’s oath will apply to “banking service providers” working at banking and investment services agents for a credit institution. The scope covers four categories of individuals at the agent: members of senior management, managers responsible who assume de facto responsibility for or supervise other staff, banking and investment services agents registered with the FSMA as natural persons, and all other persons who directly participate in the exercise of banking activities or services. The newsletter flags operational points for attention, including what changes apply from 15 July 2026, where the oath must be sworn, which information on banking service providers must be registered, and where to find further information.
