VAMP Merchant Fraud Ratio Thresholds
New Visa rules go into effect soon:
Now (Advisory): No fines, monitoring begins
Oct 1, 2025: Enforcement begins at 2.2% fraud ratio
Apr 1, 2026: Drops to 1.5% threshold
(Future: May drop to 0.9%)
Example Merchant
Merchant A
TC40 Fraud
100
TC40 Fraud
4,500
Fraud Ratio
2.22%
Status
Note: Most merchants see fraud ratios double when TC40s are included—even if chargebacks (TC15) remain low.
Why Every Merchant Should Be Concerned
Here’s why this matters:
Acquiring banks must keep their entire portfolio fraud ratio under 0.30%.
If your MID has a fraud ratio above 0.30%—even if your chargebacks are low—you may be terminated to protect the BIN, well before Visa ever takes action.
Bottom line: It’s not just about staying under Visa’s thresholds anymore. You need to be low-risk for your processor, too.

Why Pre-Dispute Tools Aren’t Enough Under VAMP
Tools like RDR, CDRN, Ethoca, and Order Insight are often referred to as pre-dispute tools. They help resolve disputes before they become chargebacks by issuing quick refunds or sharing transaction details with the cardholder’s bank. These tools are incredibly useful for protecting your chargeback ratio—and you should absolutely be using them.
But here’s the problem:
They do nothing to prevent TC40 fraud reports. And under the new VAMP rules, TC40s count just as much as chargebacks in Visa’s fraud ratio calculation.
That means you could be doing everything right with pre-dispute resolution and still get flagged—or even terminated—if you’re not also preventing fraud complaints at the source.
