Your banking app has already completely transformed everyday banking. The next shift’s even bigger—banking that feels like a conversation. At the end of April, just a few days before becoming CEO of Belfius, we engaged with Olivier Onclin to unpack what it truly takes to move from traditional digital channels to conversational AI, and why the "wow" factor only matters if the underlying processes are rebuilt end to end.
We get practical about how AI in banking has evolved over decades, from scripted automated decision making in credit models to compliance automation, and now to large language models that can reshape the client experience. Olivier explains why efficiency and customer experience are tightly linked, why the talent challenge is real even for well-prepared organisations, and why late starters still need to jump in quickly while treating AI as a management journey, not a plug-in tool.
Next, we explore trust in AI. Olivier breaks it down into four clear dimensions: transparency (people should know they're talking to a machine), security (including cybersecurity for consumers), a human layer (AI cannot replace basic humanity), and sovereignty. When it comes to sovereignty, we discuss European AI and why Belfius favours European providers when performance is comparable, including a partnership with Mistral, alongside the broader need for resilient infrastructure and cooperation across European players.
We also tackle the uncomfortable topic of ROI. If the best transformations can take seven to ten years to pay back, how do leaders justify AI investments in uncertain times and short reporting cycles? If you care about digital transformation, AI governance, cybersecurity, and the future of customer experience in financial services, this conversation will provide a sharp framework and real-world constraints.
