World Economic Forum warns AI-driven fraud is top financial risk for banks

At the World Economic Forum Annual Meeting in Davos (Jan 19–23, 2026), the WEF published its Global Cybersecurity Outlook. The report says cyber-enabled fraud is “one of the most pervasive global threats” and found 73% of respondents were affected or knew someone affected in 2025. It also notes CEOs now rank fraud and phishing above ransomware. Independent industry surveys published the same week show fraud amplified by AI tools climbing to the top of boardroom concerns.

WEF and banking surveys point to specific AI techniques — deepfakes, synthetic identities, and AI-crafted phishing — as factors that increase attack scale and plausibility. Defenders are also adopting AI for detection and orchestration, which speeds the offense–defense cycle.

For financial institutions, the near-term effect is greater regulatory and supervisory focus on model safety, explainability, and control frameworks for AI in customer-facing and transaction systems. Expect audits, stricter vendor due diligence, and pressure to deploy real-time detection and identity-resilience tooling.

Why It Matters

• Audit and compliance teams should prepare for intensified regulator scrutiny on AI model safety, explainability, and operational controls in fraud detection and transaction systems.
• Security engineering must prioritize real-time identity resilience (deepfake and synthetic identity detection) and adaptive phishing defenses that support model explainability.
• Banks should add AI-specific vendor risk checks, including abuse-resilience and auditability, to procurement and third-party reviews before renewal or deployment.
• Incident response and business continuity plans should incorporate AI-driven fraud tabletop exercises and readiness checks for real-time detection and mitigation tools.
