Row-based ML catches individual bad actors but misses coordinated fraud rings. Graph Neural Networks propagate relational context through transaction networks — here's the architecture, the PyTorch Geometric code, and the production gotchas that matter more than model choice.
Commonwealth Bank deployed an agentic AI system that doesn't just flag fraud — it generates new detection rules in real-time, then hands them to humans for approval. The 20% fraud loss reduction is real. So is the governance architecture required to make it not a liability.
Google's Deep Research Max targets FactSet and PitchBook, Oracle ships pre-built AI agents for treasury and trade finance, Experian drops 80-model fraud detection, and Wealth.com raises $65M as AI operating systems eat the wealth management industry alive.
From BlackRock's Asimov to Feedzai's RiskFM and JPMorgan's $19.8B tech budget, the finance sector's AI transformation hit multiple inflection points simultaneously in Q1–Q2 2026.
