Payment Fraud Grows More Complex as Banks and Consumers Face New AI Threats

A Federal Reserve survey of risk officers at more than 400 financial institutions found that fraud involving debit cards, checks, ACH payments and wire transfers is rising across the board. Account takeovers, compromised credentials and money-mule accounts often leave losses undetected until after the fact, threatening payment security and customer trust.

The Fed released the survey on April 28, 2026, reporting that no major fraud category had declined. A 2025 report from PYMNTS Intelligence and Block found that unauthorized third-party fraud accounted for 71% of cases and losses, while 68% of financial institutions had increased detection spending. No aggregate loss figure was disclosed, and banks are accelerating the deployment of AI, behavioral analytics and real-time monitoring.

Dutch fintech company Adyen used its global merchant payments network to track fraud trends, analyzing $1.6 trillion in transaction data for its 2025 Payment Fraud Report. AI has become a tool both for merchant risk controls and criminal attacks, shifting payment-security threats from isolated incidents toward identity-based fraud that can be coordinated at scale.

Adyen said global payment fraud losses fell 20% in 2025, but the risk became more concentrated: just 5% of identities linked to fraud accounted for 58% of the value of fraudulent transactions. The report warned that the spread of generative AI allows attackers to create fake content and coordinate their activities more quickly, while merchants must also use AI to strengthen real-time detection.
