Visa Just Lowered the Bar: What the April 2026 Threshold Drop Means for Your Stripe Account

On April 1, 2026, Visa's merchant-level threshold for "Excessive" classification in the Visa Acquirer Monitoring Program (VAMP) dropped from 2.2% to 1.5% for merchants in North America, the EU, and Asia Pacific.

If your combined fraud and dispute ratio was between 1.5% and 2.2% on March 31, you were compliant. On April 1, without processing a single new transaction, you weren't.

No email from Visa. No warning from Stripe. The floor just moved under you.

What Actually Changed

VAMP — Visa's unified monitoring programme that replaced VDMP and VFMP in April 2025 — tracks what's called the VAMP ratio:

VAMP Ratio = (Fraud reports + Total disputes) ÷ Total settled transactions

Before April 2026, a merchant was classified as "Excessive" at 2.2%. Now it's 1.5% — a 32% reduction in the allowable threshold.

The fine for merchants at the Excessive level: $8 per fraudulent or disputed transaction.

At 5,000 monthly transactions with a 1.8% combined ratio, that's 90 flagged transactions. At $8 each, that's $720/month in fines — for a ratio that would have been compliant two weeks ago.

Who's Affected

This hits three groups particularly hard:

Merchants between 1.5% and 2.2%. You were below the line. Now you're above it. If you haven't checked your ratio since March, check it today.

High-volume merchants with thin margins. The $8/transaction fine is assessed on every TC40 (fraud report) and TC15 (dispute) transaction. At scale, this compounds quickly. A merchant processing 50,000 transactions/month at 1.6% is looking at 800 flagged transactions — $6,400/month in potential fines.

Merchants who rely on Radar defaults. If your Stripe Radar isn't configured with custom rules, you're likely experiencing more false declines than necessary and not catching preventable fraud. Both of these contribute to the VAMP ratio — fraud reports from uncaught fraud, and disputes from blocked legitimate customers who went to their bank instead.

The Enforcement Timeline

This didn't happen overnight. Visa telegraphed it:

The acquirer threshold of 0.5% has been live since January. That means Stripe has been under pressure from Visa for months — and that pressure flows downhill to merchants.

Why Your Processor Might Act Before Visa Does

Here's the part most merchants miss: Visa's fines are assessed on the acquirer (Stripe), not directly on you. Stripe absorbs the fine, then decides what to do about it.

Their options:

1. Pass the fine through — charge you directly
2. Impose reserves — hold 5–10% of your volume as a buffer
3. Restrict your account — pause payouts until the ratio drops
4. Terminate — if the problem persists, end the relationship

Stripe doesn't publish which option they'll choose for a given merchant. What they do publish is that they monitor dispute rates and may take action "before" reaching programme thresholds. In practice, this means Stripe may restrict your account at levels lower than Visa's formal threshold — because Stripe is trying to keep their own aggregate ratio below the acquirer-level line.

The VAMP Ratio vs. Stripe's Dispute Rate

Important distinction: Visa's VAMP ratio and Stripe's dispute rate are calculated differently.

VAMP Ratio includes both:

• TC40 reports (fraud alerts from issuing banks — these can happen without a formal dispute)
• TC15 transactions (actual disputes/chargebacks)

Stripe's dispute rate typically counts only formal disputes against payments.

This means your VAMP ratio is almost always higher than your Stripe dispute rate. You might see 0.6% in your Stripe dashboard and assume you're safe, while your VAMP ratio (including fraud reports you never see in Stripe) is actually 1.2%.

The fraud reports (TC40s) are particularly insidious because they don't show up as disputes in your Stripe dashboard. They come from issuing banks who flag transactions as potentially fraudulent based on cardholder reports. You may never know they exist — but Visa counts them.

What to Do Right Now

1. Check Your Actual Ratio

Your Stripe dispute rate is not your VAMP ratio. To approximate your VAMP ratio:

• Go to Stripe Dashboard → Radar → look at early fraud warnings (these approximate TC40s)
• Add your early fraud warning count to your dispute count
• Divide by total transactions for the month

If the result is above 1.5%, you have a problem that needs immediate attention.

2. Address Fraud Reports, Not Just Disputes

Early fraud warnings (EFWs) that convert to disputes hit you twice — once as a TC40, once as a TC15. Stripe's data shows 80% of EFWs convert to formal disputes. If you're getting EFWs and not acting on them, your VAMP ratio is climbing from both sides.

When you receive an EFW on a charge less than or equal to your dispute fee, refund it immediately. The refund costs you the sale. Ignoring it costs you the sale plus the dispute fee plus a permanent mark on both your dispute rate and your VAMP ratio.

3. Configure Stripe Radar

Default Radar rules are conservative — they catch fraud, but they also block legitimate transactions. Every false decline is a customer who might call their bank instead of trying again, which creates a fraud report (TC40) or dispute (TC15) that hits your VAMP ratio.

Set up custom rules for your business: allow lists for repeat customers, adjusted thresholds for low-value recurring transactions, and 3D Secure for high-risk transaction types instead of outright blocking.

4. Audit Your Billing Descriptor

The #1 cause of "friendly fraud" — disputes filed by real customers who don't recognise a charge — is an unclear billing descriptor. If your descriptor shows "STRIPE* ACMELLC" instead of "Acme Subscription," you're generating disputes that are entirely preventable.

5. Monitor Weekly

Monthly monitoring is an autopsy. At the new 1.5% threshold, a bad week can push you over the line before the month ends. Weekly checks give you time to investigate and respond.

The Bigger Picture

Visa has been tightening dispute thresholds consistently:

• Pre-2025: VDMP and VFMP as separate programmes with higher thresholds
• April 2025: Unified into VAMP with initial 2.2% merchant threshold
• January 2026: Acquirer Above Standard at 0.5%
• April 2026: Merchant Excessive drops to 1.5%

The direction is clear. Thresholds will continue to tighten. Building dispute prevention into your operations now isn't optional — it's the cost of processing cards.

And remember: the VAMP ratio includes fraud reports, not just disputes. Stripe's dashboard doesn't give you full visibility into your TC40 count. The number you see is almost certainly lower than the number Visa sees.

Frequently Asked Questions

What is the Visa VAMP threshold as of April 2026?

The merchant-level "Excessive" threshold dropped from 2.2% to 1.5% on April 1, 2026, for merchants in North America, the EU, and Asia Pacific. The acquirer-level "Above Standard" threshold is 0.5% (since January 2026).

What's the fine for exceeding the VAMP threshold?

$8 per flagged transaction (TC40 fraud report or TC15 dispute) for merchants at the Excessive level. This is assessed to the acquirer (Stripe), who typically passes the cost to the merchant.

Does my Stripe dispute rate equal my VAMP ratio?

No. The VAMP ratio includes both fraud reports (TC40) and formal disputes (TC15). Your Stripe dashboard shows disputes but not all TC40 fraud reports. Your VAMP ratio is almost always higher than what Stripe shows.

Can I be compliant in Stripe but non-compliant in VAMP?

Yes. Because VAMP includes fraud reports that don't appear as disputes in Stripe, and because the acquirer-level threshold (0.5%) is lower than Stripe's published threshold (0.75%), it's possible to look clean in Stripe while being flagged by Visa.

What happens if I exceed the threshold?

After a three-month grace period for first-time offenders, Visa assesses fines to your acquirer. Your acquirer (Stripe) then decides whether to pass the fine through, impose reserves, restrict your account, or terminate the relationship.

What should I check first?

Your early fraud warnings in Stripe Radar. If you're getting EFWs and not acting on them, your VAMP ratio is climbing from a source you can't see in your standard dispute rate.
