European Banks Weigh How to Embed AI Across Core Systems

According to Finextra, the central question being posed to financial institutions is deceptively simple: how should they embed AI into their core banking systems? It is a framing that acknowledges the difference between bolting AI onto a single product and integrating it more deeply across the technology that underpins a bank's operations.

Front-to-Back Modernisation

The Finextra coverage positions the conversation around modernising banking systems "from front to back" — language that points to the full span of a bank's architecture. At the front end sit the tools customers and relationship managers interact with directly. At the back end lie the processing engines, reconciliation systems, and record-keeping functions that keep a bank running.

Embedding AI across that entire chain is a more ambitious undertaking than deploying a chatbot or a single fraud-detection model. It raises questions about how legacy core systems, often built decades ago, can accommodate newer AI-driven capabilities, and how institutions can do so without disrupting the reliability that regulators and customers expect.

The event framing also links AI with human resources and financial services, suggesting that the people and organisational structures inside banks are part of the modernisation equation, not just the technology itself. How teams are organised, trained, and equipped to work alongside AI systems is emerging as a factor in whether these projects succeed.

The Open Questions

Finextra's framing leaves the core question open rather than prescribing an answer, reflecting where much of the industry currently stands. There is broad agreement that AI has a role to play in modern banking, but far less consensus on the sequencing, governance, and architecture required to embed it responsibly across core systems.

For European institutions weighing these choices, the stakes include regulatory compliance, operational resilience, and competitiveness against digital-native challengers. As Finextra reported, the discussion is less about whether to adopt AI and more about how to do so in a way that touches every layer of the bank.

Nigeria's central bank has withdrawn the operating licences of 46 microfinance banks, saying they no longer meet the requirements to function as licensed institutions.
