# Global bank cuts fraud false positives by 62%

A top-three global bank has reduced false positives in fraud alerts by 62% after rebuilding its decisioning layer with iAastha.

The programme kept the incumbent detection model and changed everything around it: thresholds tied to investigator capacity, explanations attached to every alert, and a feedback loop that retrains on what investigators actually closed.

A rebuilt decision layer — not a new model — returned investigator trust and cut alert noise by nearly two thirds.
