Or did VAMP simply expose risk practices that were already broken?
VAMP (Visa Acquirer Monitoring Program) is Visa’s framework for monitoring fraud and dispute activity across merchant portfolios.
Did Visa break merchant onboarding?
Or did it just make unmanaged risk harder to approve?
It’s an important distinction.
Recent updates introduced stricter thresholds and greater accountability for acquirers, payment service providers, and sponsor banks.
The result? Risk is being scrutinized much earlier in the onboarding process.
For years, parts of the payments industry operated on a “board now, review later” model. Merchants were approved quickly, processing volumes grew, and fraud, disputes, or operational issues were often addressed after the fact.
VAMP changed the economics of that approach.
Under Visa’s updated framework, acquirers and payment providers are being evaluated not only on individual merchant performance but on the health of their overall portfolio. The result is a fundamental shift in underwriting, risk management, and merchant onboarding.
The data tells the story.
Visa’s acquirer-level fraud threshold dropped from 1.0% to 0.5%, significantly increasing the cost of poor risk management. At the merchant level, the excessive VAMP ratio threshold was reduced from 2.2% to 1.5%, creating far less room for operational or risk-related issues to go unnoticed.
As a result, underwriting is becoming more data-driven.
Ownership structures. Traffic sources. Fulfillment processes. Fraud controls. Chargeback history. Growth projections. All critical indicators of portfolio risk.
What we’re seeing across the industry is not a universal tightening of approvals.
Strong merchants with transparent operations, realistic growth plans, and effective controls are often moving through onboarding faster because providers have greater confidence in what they’re underwriting.
The businesses facing the most friction tend to be those with inconsistent documentation, unexplained fraud patterns, weak operational controls, or business models that don’t align with their transaction profile.
That’s not payments becoming more restrictive.
It’s risk assessment becoming more precise.
For merchants, PSPs, ISOs, sponsor banks, and acquirers alike, VAMP represents a broader shift in payments: portfolio quality is becoming just as important as portfolio growth.
It’s no longer about how quickly a merchant can be boarded.
It’s whether the risk can be understood before it becomes expensive.
