European banks face more complex fraud, survey finds

A survey of 200 European fraud leaders, conducted with NICE Actimize, finds fraud activity is expanding across payment channels and becoming more technically complex. The survey will be discussed in an upcoming webinar that brings together fraud executives and vendors to map threats and controls for 2026. Panelists listed for the event include Chris Ainsley of Santander UK, Joe Bristow of NICE Actimize and David Laramy of Klarna, with Sharon Kimathi moderating.

Respondents reported that card fraud and account takeover remain significant. They also reported an increase in attacks that cross channels and use new tools. Examples identified by participants include payment instructions generated or amplified by generative AI and scams that use virtual assets as a means of settlement or laundering.

Survey participants said banks are increasing use of machine learning and other AI tools to detect multi-channel signals, spot new patterns and scale monitoring. Many named AI as a primary investment area. At the same time, respondents reported slow integration of AI into existing systems, citing legacy infrastructure, fragmented data, limited in-house AI expertise and the complexity of deploying models across product lines and countries.

The survey found uneven preparedness across European markets. Some institutions reported well-funded fraud teams, advanced analytics and rapid model deployment. Other firms reported scarce resources, limited tooling and less developed fraud strategies. Participants linked these differences to gaps in detection speed and coverage: larger teams can apply AI-enhanced controls across cards, accounts and payments, while smaller teams often rely on rule-based systems and manual review.

Many respondents expressed concern about whether current controls will be adequate over the next few years. Firms identified priority investments in model development, data integration, stronger authentication and improved cross-channel monitoring. Panelists said they will discuss how to prioritise those investments and accelerate modernisation during the webinar.

Participants highlighted practical barriers that slow progress from pilots to production controls. They reported a need for better data sharing within organisations, clearer processes for model deployment and more staff with combined fraud domain and data science skills.

Background: European banks have long used rules, device signals and manual review to fight card fraud and account takeover. The emergence of new payment rails, wider use of AI by customers and attackers, and greater use of virtual assets have broadened the threat surface. The survey aims to provide a benchmark of current capabilities and to identify where further investment and coordination are needed. The webinar will present the survey findings and convene industry experts to discuss steps for strengthening multi-channel fraud defences in 2026 and beyond.
