AI in Financial Services: What Works, What Doesn’t, and What Comes Next

The model is only the beginning. The real questions are about workflows, authority, economics, trust, and who learns fastest.

Financial institutions are no longer asking whether AI will matter. They are trying to separate useful systems from convincing demos—and move from experiments to accountable work.

This series examines that transition from the operator’s side: what reaches production, what breaks, how governance must change, and where durable advantage will remain when capable models are available to everyone.

The essays draw on current evidence from the ECB, Bank of England, FCA, BIS, EBA, FSB, European legislation, and financial institutions deploying AI at scale.
