Why Bigger Fraud Budgets Aren’t Enough

Banks are spending more to fight fraud. Yet fraud is still moving faster than many institutions can operationally respond. 

The 2026 ProSight State of Fraud Prevention Survey shows the scale of the gap. Fifty-three percent of respondents said their institutions increased fraud budgets by 5% or more this year. At the same time, 85% said the fraud threat environment is changing faster than they can respond. 

More funding may be necessary, but the survey suggests the real challenge is turning investment into usable fraud-fighting capacity. Alert overload; staffing limitations; data quality or availability; legacy infrastructure; vendor limitations; and customer frustration with additional tasks, verification, and documentation all ranked ahead of budget constraints. 

For bank leaders, the work starts with the places where response capacity breaks down: 

Watch the alert burden. More detection can create more noise. If teams are already struggling with alert overload, adding tools without improving workflow may deepen the problem. Fraud teams need ways to sort, escalate, and act quickly enough for the controls to matter. 

Treat staffing as a fraud-control issue. Fraud prevention depends on judgment, follow-up, and coordination across departments. Maria Noriega, product and community manager for ProSight’s Fraud Alert Network, said “the proliferation of fraud means that even teams at large institutions can feel stretched thin.” The pace and capability of fraudsters, she added, leave many teams “trying to keep up and even triaging.” 

Make the data usable. Data quality and availability were among the leading constraints named in the survey. The issue becomes even more important as institutions invest in new technology, including AI-enabled tools. Poor or fragmented data limits how much those investments can change day-to-day fraud operations. 

Set the right verification level. Fraud controls increasingly ask customers to pause, verify, confirm, or provide documentation. The survey shows most institutions lean toward protection: 50% said they prioritize fraud mitigation, while 41% said they balance fraud mitigation and customer experience equally. The work for banks is to add enough scrutiny to reduce losses without making the process so confusing or frustrating that customers cannot follow it. 

The takeaway: Fraud spending is rising, but money alone does not create response capacity. The institutions that make the most progress will be the ones that connect investment to execution: fewer unmanageable alerts, stronger staffing, cleaner data, better infrastructure, useful vendors, and controls that customers can understand well enough to follow.
