The financial services sector continues to evolve at a rapid pace while remaining one of the key pillars of the Belgian economy. It is also one of the most heavily regulated sectors, where supervisory authorities such as the National Bank of Belgium (NBB), the Financial Services and Markets Authority (FSMA), and the European Central Bank (ECB), together with European regulations (including DORA, AML, and CRD/CRR), place continuous pressure on governance, risk management, and operational resilience. Combined with ongoing digital transformation, these developments create complex and strategic challenges for financial institutions.
