Point 1: Your chargebacks and fraud reports now count as one ratio — and one transaction can hit you twice. Visa's new VAMP formula combines TC40 fraud reports and TC15 disputes into a single metric. Most merchants have no idea what their real number is.
Point 2: The threshold is dropping. Current merchant limit is 1.5%. In April 2026, it tightens further. Your processor may already be enforcing stricter internal limits to protect their own portfolio.
Point 3: Fines are $8 per disputed transaction. But the real risk is account termination. Once you're on the MATCH list, no processor will onboard you. Your business stops accepting cards.
Point 4: You're also overpaying — and don't know it. While your VAMP risk grows, hidden markups, misrouted transactions, and unnecessary fees drain $5K–$20K/month from merchants at your volume.
October 2025 — Enforcement began. $8/transaction fines active for merchants exceeding Excessive thresholds.
January 2026 — Above Standard enforcement live for acquirers at 0.3%. Your processor is reviewing your account right now.
April 2026 — Merchant Excessive threshold drops from 2.2% to 1.5% in US, Canada, EU. The window to fix your ratio is closing.
Bold closing line: Every month you wait, your historical dispute data makes compliance harder. Merchants who act now have 60 days to fix their ratios before the April threshold change.
