What is High-risk merchant?
Also: high-brand-risk merchant
A merchant whose vertical, business model, or chargeback profile makes standard acquirers reluctant to board them.
A High-risk merchant is a business classified by acquiring banks and card schemes as having an elevated probability of financial loss, reputational damage, or regulatory scrutiny.
This classification is not subjective; it is a risk assessment based on the merchant's business model and industry vertical, identified by its Merchant Category Code (MCC).
Industries commonly deemed high-risk include those with high chargeback ratios (e. g. , nutraceuticals, subscription trials), long periods between payment and fulfilment (e. g. , travel, event tickets), or those operating in legally ambiguous or brand-sensitive areas (e. g. , online gaming, dating, adult entertainment).
Acquirers use this classification to determine their appetite for underwriting the business.
Financial risk is the primary concern. A high chargeback ratio, for example, can trigger scheme monitoring programmes like Visa's Dispute Monitoring Program (VDMP) or Mastercard's Excessive Chargeback Program (ECP).
If a merchant's chargeback-to-transaction ratio exceeds 0.9% (for Visa) or 1.5% (for Mastercard), the acquirer faces significant monthly fines. Consequently, acquirers impose stricter terms on high-risk merchants, including higher transaction fees (MDR), mandatory settlement reserves, and stringent processing volume caps.
The nuance often missed is that being 'high-risk' can also be due to processing history, such as having a previous MID terminated, which leads to placement on the MATCH list and an automatic high-risk designation, irrespective of the industry.
Worked example
A European startup selling subscription-based fitness supplements (MCC 5499) is classified as high-risk due to the industry's association with high chargeback rates from 'Friendly fraud' and disputes over recurring billing. Mainstream acquirers decline their application.
They approach Cardflo, a specialist high-risk acquirer. Cardflo's underwriting team approves the merchant but with specific conditions.
The merchant's pricing is IC++ with a 250 basis point (2.5%) acquirer markup, compared to the 80bps a low-risk merchant might get.
A 10% rolling reserve is implemented for 180 days, meaning 10% of each day's settlement is held by the acquirer for six months on a first-in, first-out basis to cover potential chargebacks.
The merchant must also process all transactions via 3D Secure to mitigate fraud risk and is assigned a monthly processing volume cap of €50,000, which will be reviewed after three months of stable processing.
Scheme notes
Visa and Mastercard's risk monitoring programmes are the primary mechanism through which schemes manage high-risk merchants. For chargebacks, a merchant exceeding 100 disputes and a 1.5% ratio enters Mastercard's ECP, with fines starting at $1,000 per month.
For fraud, a merchant with over $75,000 in fraudulent transactions and a 0.9% ratio enters Visa's Fraud Monitoring Program (VFMP), with fines starting at $25,000.
For brand-risk violations related to illegal activity, Mastercard's Business Risk Assessment and Mitigation (BRAM) programme can issue fines of over $100,000 per incident. A merchant being placed in any of these programmes puts immense pressure on their acquirer, often leading to MID termination.
Why it matters for merchants
The commercial impact of being a High-risk merchant is significant. It primarily means higher costs and restricted cash flow.
Higher MDRs directly reduce profit margins, while rolling reserves tie up working capital that could be used for growth. Many high-risk merchants require multiple MIDs across different acquirers to build redundancy and capacity, an operational overhead managed by payment orchestration platforms.
For these businesses, securing any processing is a victory, but optimising it is the challenge.
Cardflo's network of specialist high-risk acquirers allows us to place merchants with the partner best suited to their specific vertical and risk profile, increasing the likelihood of approval and providing a path to more favourable terms as the business proves its stability.
Frequently asked
How does high-risk status affect processing costs for a business?
High-risk merchants usually pay higher processing fees than standard retailers because the acquirer builds a risk premium into the pricing. These costs are often reflected in higher per-transaction fees, increased interchange markups, and monthly account maintenance charges to cover the overhead of stricter compliance monitoring.
What impact do card scheme monitoring programmes have on these merchants?
When a merchant exceeds established chargeback or fraud thresholds, they are placed into monitoring programmes like the Visa Fraud Monitoring Programme (VFMP).
Being in these programmes often results in monthly fines and may lead to the eventual termination of the merchant account if the ratios are not reduced within a specified period.
Will I always be a High-risk merchant, or can my status change?
Your status can change, but it requires a sustained period of stable processing. To be reclassified to a lower risk tier, you typically need to maintain a chargeback ratio below 0.5% and a fraud ratio below 0.2% for at least 6-12 consecutive months.
Demonstrating strong performance may allow you to renegotiate terms with your acquirer, such as reducing your rolling reserve from 10% to 5% or having it removed entirely.
My business was rejected by Stripe. Does that automatically make me high-risk?
Not necessarily, but it's a strong indicator. Mainstream processors like Stripe and PayPal have a very low-risk appetite and maintain a broad list of prohibited businesses that includes many industries that specialist acquirers are willing to support.
Being rejected by them means you fall outside their standard risk model and will need to apply to a payment provider that specialises in underwriting businesses in sectors like yours.
What is a rolling reserve and how does it work?
A rolling reserve is a risk-mitigation tool where the acquirer holds a percentage of your daily sales for a set period.
For example, a 10% reserve held for 180 days means 10% of Monday's sales are held until 180 days later, 10% of Tuesday's sales are held until 181 days later, and so on.
This creates a constantly replenishing fund that the acquirer can use to cover losses from chargebacks, protecting them from a merchant who ceases trading but leaves behind significant liabilities.
Are the fees for high-risk processing always higher?
Yes, processing fees are invariably higher to compensate the acquirer for the increased financial risk and operational overhead. A low-risk e-commerce merchant might pay an acquirer markup of 40-80 basis points over interchange.
A High-risk merchant can expect to pay a markup of anywhere from 200 to 700 basis points (2% to 7%), depending on their specific industry, chargeback history, and processing volumes.
What is the MATCH list and how do I know if I'm on it?
The MATCH list, now officially called the Terminated Merchant File (TMF) by Mastercard, is a database used by acquirers to identify merchants whose accounts were previously terminated for cause.
Common reasons for being added include excessive chargebacks (Reason Code 14) or fraudulent activity (Reason Code 04). Acquirers are required to check the TMF before onboarding a new merchant.
You will not be directly notified, but if you find it nearly impossible to get approved for a new merchant account, it is highly likely you have been added to the list.
