At a Scarsdale, N.Y., branch, seasoned teller Karen Battista stopped an 81‑year‑old widow from moving $9,000 into a suspicious account after a phone call claimed Chase had opened a new account for her. Battista’s quick check revealed a scammer named “Michael” listening on the line.

JPMorgan Chase hired a behavioral scientist, Elizabeth Huppert, to train staff on psychological tactics scammers use. Early pilots show the new scam‑interruption teams cut fraudulent transfers, helping employees spot red flags before money leaves the account and reduce losses across the network for customers and shareholders alike in coming quarter.

The FBI’s Internet Crime Complaint Center logged $21 billion in cybercrime losses in 2025, a jump of more than 25 percent from 2024. As banks invest in behavioral analytics and real‑time intervention, tellers and call‑center agents become frontline defenders, turning routine customer service into fraud prevention for banks and their clients today.

These frontline interventions shift banks’ cost structures, turning fraud prevention from a reactive, expensive process into a proactive, data‑driven strategy. Investors will watch how effective the new teams are, as reduced loss ratios could translate into higher profit margins and a competitive edge in a market where cyber‑risk drives valuation.
