VAMP enforcement tightened April 1, 2026 — merchant Excessive threshold drops to 1.5%
Visa's April 2026 threshold change is now in effect. The merchant Excessive threshold has dropped from 2.2% to 1.5% across the US, Canada, EU, and Asia-Pacific — meaning merchants who were previously in a gray zone are now formally classified as Excessive and subject to $8/event fines.
Enterprise fraud teams should audit their current TC40 + TC15 combined ratio against settled CNP volume now. The dispute response link is often underestimated: winning disputes with compelling evidence removes qualifying transactions from the VAMP numerator.
