Open Banking for High-Risk Merchants: A New Path to Payments?

Introduction

High-risk merchants know the payment processing drill all too well.

You apply for a merchant account and get hit with processing fees two to three times higher than standard businesses. Your payment gateway flags your business category before a single transaction goes through. Your payment provider demands a rolling reserve that freezes working capital you cannot afford to lose. And the moment your chargeback ratio nudges past 1%, a termination notice lands in your inbox before you have a chance to course-correct.

The card network infrastructure was never built for businesses like yours. Open banking is now changing that conversation, not by fixing the broken card system, but by offering a completely different payment rail that bypasses card networks, eliminates interchange fees, and removes the chargeback mechanism that makes high-risk payment processing so expensive and unstable.

This guide breaks down exactly what open banking offers high-risk merchants, where the real advantages lie, where the limitations remain, and how to integrate it intelligently into your existing payment stack.

What Is Open Banking? (And Why High-Risk Merchants Should Care)

Open banking is a regulated framework that allows licensed third parties to initiate payments directly from a customer’s bank account using standardised APIs, with the customer’s explicit consent.

How It Works in Simple Terms

  • The customer selects “Pay by Bank” at checkout
  • They authenticate the payment through their own banking app
  • Funds transfer directly from their account to the merchant’s account
  • No card network. No interchange fee. No chargeback mechanism.

Where Open Banking Is Regulated

Region Framework Status
United Kingdom Payment Services Regulations / FCA Mature — high adoption
European Union PSD2 (Payment Services Directive 2) Mature — varies by country
United States CFPB Section 1033 / Dodd-Frank Developing — early stage
Australia Consumer Data Right (CDR) Growing
Brazil Open Finance Framework Growing

 

Open banking is not a startup concept or an emerging experiment. In the UK and EU, banks are legally required to provide API access to licensed Payment Initiation Service Providers (PISPs). The infrastructure is live, regulated, and processing real volume.

Market scale: Global open banking transaction value was estimated at $57 billion in 2023 and is projected to reach $330 billion by 2027 (Allied Market Research). For high-risk merchants watching this market develop, that growth represents a real, usable payment channel, one that operates entirely outside the card infrastructure that has made payment processing so costly for businesses in flagged categories.

The Core Problem Open Banking Solves for High-Risk Merchants

To understand why open banking matters for high-risk payment processing, you first need to understand the precise costs of the status quo.

What Card-Based Processing Currently Costs High-Risk Businesses

  • Processing fees: 3.0%–5.5% per transaction (vs. 1.5%–2.9% for standard merchants)
  • Rolling reserves: 5%–10% of daily volume held for 90–180 days
  • Chargeback fees: $20–$100 per dispute, plus ratio damage
  • Monthly minimums, statement fees, and annual account maintenance fees
  • Volume caps that restrict growth at exactly the wrong moment

For a high-risk merchant processing $500,000 annually at 4.5%, that is $22,500 per year purely in processing fees, before chargebacks, reserves, or account management costs are factored in.

What Open Banking Changes Directly

Lower transaction costs Open banking transaction fees typically range from 0.1% to 0.5% of transaction value, or flat fees between £0.10 and £0.50 per transaction. At $500,000 annual volume, the same merchant pays $500–$2,500 instead of $22,500. That is a cost reduction of up to $20,000 annually on processing fees alone.

No card network chargeback mechanism Open banking payments, once authenticated by the customer through their bank, are not subject to the Visa or Mastercard chargeback process. A customer cannot file a chargeback against an open banking payment because there is no card network to file it through. For high-risk merchants whose chargeback ratios are driven by friendly fraud, customers who received goods and initiated disputes anyway, this removal is structurally significant.

Faster settlement Card-based transactions involve multi-day settlement cycles. Open banking payments settle directly bank-to-bank, typically within seconds for domestic transactions in Faster Payments-enabled markets. Faster settlement directly improves cash flow, particularly relevant for merchants whose rolling reserves already constrain working capital.

Where Open Banking Falls Short: An Honest Assessment

Open banking is not a complete replacement for traditional payment processing infrastructure. High-risk merchants evaluating this channel need to understand its real limitations before building strategy around it.

Consumer Adoption Is Still Uneven

  • UK: Strong adoption – open banking is mainstream
  • EU: Variable by country – strong in Germany and Netherlands, weaker in Southern and Eastern Europe
  • US: Early stage – most consumers are unfamiliar with pay-by-bank flows
  • Implication: Merchants with predominantly US customer bases will see limited volume through open banking rails in the near term

Open Banking Payment Providers Have Their Own Risk Policies

Not all open banking providers accept high-risk merchant categories. PISPs are regulated entities with their own compliance frameworks. Offshore merchants, adult content businesses, cryptocurrency platforms, and cannabis-adjacent brands may find that open banking providers apply risk policies that mirror, to varying degrees, those of traditional acquiring banks.

The infrastructure is different. The risk appetite of companies operating within it is not automatically more permissive.

Refund and Dispute Processes Are Less Standardised

The absence of a card chargeback mechanism is an advantage for merchants facing friendly fraud. It creates a different challenge for legitimate customer disputes.

  • There is no standardised open banking refund infrastructure equivalent to the card network dispute framework
  • Merchants must build or integrate refund processes separately
  • Customers accustomed to card chargebacks find bank dispute processes less familiar and more effortful
  • This is both an advantage (reduces frivolous disputes) and a complication (legitimate disputes require more operational process)

Card Payments Cannot Be Abandoned

No high-risk merchant can realistically eliminate card-based payment processing in favour of open banking rails without losing a significant proportion of customers. Cards and digital wallets remain the dominant global payment method. Open banking works as an addition to the payment stack, not a replacement for it.

How High-Risk Merchants Are Using Open Banking Practically

The most sophisticated high-risk merchants are not treating open banking as an either/or decision. They are deploying it as a targeted payment rail for specific use cases where its advantages are most pronounced.

1. High-Value Transactions

For subscription businesses with higher average ticket sizes, annual plans, premium tiers, enterprise subscriptions, open banking offers a compelling alternative to card payments.

  • The cost saving per transaction is more meaningful at higher amounts
  • Customers making deliberate, considered purchases are more willing to authenticate through an open banking flow
  • Friendly fraud risk is higher on larger amounts, giving bad actors more incentive to dispute

Practical approach: Route all transactions above a defined threshold (£200 or $250, for example) through open banking by default, with card payment available as an alternative.

2. Failed Card Payment Recovery

Failed card payments, expired cards, insufficient funds, bank declines, represent lost revenue for every subscription merchant.

How open banking helps:

  • Customer receives notification that their card payment failed
  • One-click option to complete payment via bank account directly
  • Recovers revenue that would otherwise be lost
  • Uses a payment method that bypasses the card infrastructure that generated the failure

3. Cross-Border Payments for Offshore Merchants

For offshore merchants managing payments across multiple currencies and jurisdictions, open banking’s direct bank-to-bank architecture offers:

  • Reduced foreign exchange costs versus card-based international transactions
  • Faster settlement in markets with mature open banking infrastructure
  • Simplified cross-border payment collection in the UK, EU, and Australia

4. Managing Chargeback Ratio Exposure

High-risk merchants approaching card network monitoring thresholds are using open banking to manage their chargeback ratio arithmetic.

  • Route customers statistically more likely to dispute, recent complainants, customers who have previously initiated enquiries, to open banking payment options
  • These customers complete payment outside the card chargeback mechanism
  • The proportion of at-risk transactions exposed to card disputes decreases
  • Chargeback ratio improves without requiring changes to underlying operations

How to Choose the Right Open Banking Payment Provider

For high-risk merchants evaluating open banking, provider selection follows a process similar to selecting a high-risk merchant account or payment gateway. The key criteria to evaluate:

Regulatory Status

  • UK merchants: Confirm FCA authorisation as a PISP
  • EU merchants: Confirm PSD2 licence in relevant jurisdiction
  • Never work with unregulated entities claiming open banking capabilities

Merchant Category Acceptance

  • Confirm explicitly, in writing, that your specific business category is accepted
  • High-risk payment categories require written confirmation, not assumed from general marketing language
  • Categories to specifically confirm: subscription billing, nutraceuticals, adult content, offshore merchants, gambling-adjacent

Settlement Terms

  • Confirm settlement timeline: same-day vs next business day vs longer
  • Confirm settlement currencies and FX conversion fees for cross-border transactions
  • Compare against your current payment provider terms

Refund and Dispute Infrastructure

  • Understand precisely how refunds are processed and on what timeline
  • Understand what happens when a customer disputes a payment through their bank’s regulatory complaint process
  • Confirm the operational process required from your team for each dispute type

Integration and Conversion Rate

  • Open banking requires customer authentication through their bank, a flow unfamiliar to many consumers
  • Evaluate the provider’s checkout UX and conversion optimisation
  • Request real conversion rate data for customer bases comparable to yours

Fraud protection AVS, CVV, 3DS2 Bank-level authentication
Refund standardisation Standardised card network process Provider and bank dependent
Cross-border capability Wide but expensive Growing, lower cost
Account stability Termination risk at 1% chargeback Less exposure to card network rules

The Verdict: Is Open Banking Right for Your High-Risk Business?

Open banking is a genuinely meaningful development for high-risk merchants, not a revolution, but a material expansion of the available payment processing infrastructure.

The advantages are real:

  • Significantly lower transaction costs
  • Removal of the card chargeback mechanism for friendly fraud
  • Faster settlement and improved cash flow
  • Simplified cross-border payments for offshore merchants

The limitations are equally real:

  • Consumer adoption is still building in most markets
  • Open banking payment providers are not uniformly permissive with high-risk merchant categories
  • The absence of a card chargeback creates both advantages and complications
  • Card-based processing cannot be abandoned in favour of open banking alone

The right approach is to integrate open banking as a complementary channel, targeted at specific use cases, managed alongside robust card payment processing infrastructure, and treated as one tool in a diversified payment stack rather than a single solution to a structural problem that predates the technology by decades.

High-risk merchants who approach open banking strategically, not reactively, will extract real value from it. Those who abandon traditional merchant accounts and payment gateways prematurely in its favour will lose customers, not gain advantage.

Frequently Asked Questions

Can open banking completely replace a high-risk merchant account?

No, not currently. Cards and digital wallets remain the dominant global payment method. Most consumers expect to pay by card at checkout. Open banking works most effectively as a complementary payment channel alongside traditional merchant accounts, not as a full replacement. Merchants who eliminate card processing entirely will lose a significant proportion of customers.

Does open banking eliminate chargebacks for high-risk merchants?

Open banking payments are not subject to the Visa or Mastercard chargeback mechanism, which removes a significant vector for friendly fraud. However, customers can still dispute open banking payments through their bank’s complaint process or regulatory channels. Open banking substantially reduces chargeback exposure, it does not eliminate all payment dispute risk.

Which markets have the most mature open banking infrastructure?

The UK has the most developed open banking ecosystem for merchant payment applications, with high consumer adoption and a competitive PISP market. The EU has mature PSD2 regulatory infrastructure, though adoption varies by country. Australia, Brazil, and Canada have developing frameworks. The US is in the earliest stages of regulated open banking.

Are open banking providers subject to the same high-risk policies as card processors?

Open banking PISPs set their own merchant acceptance policies within their regulatory frameworks. Some apply risk policies comparable to traditional acquiring banks. Others have broader acceptance criteria. High-risk merchants should confirm their specific category is accepted before beginning integration, not assume that open banking infrastructure is automatically more permissive toward flagged business categories.

How does open banking affect rolling reserves?

Open banking payment providers do not universally impose rolling reserves in the way card acquiring banks do. However, regulated providers may implement financial security requirements for high-risk merchant categories. Reserve terms vary by provider and merchant risk profile and should be confirmed and negotiated during the onboarding process.

What is the typical cost difference between open banking and card processing for high-risk merchants?

Open banking transaction fees typically range from 0.1% to 0.5%, compared to 3.0%–5.5% for high-risk merchant accounts. On $500,000 in annual volume, that cost differential is up to $20,000 per year. At higher volumes, the saving is proportionally more significant and justifies the integration investment for most established high-risk businesses.

Can offshore merchants use open banking for cross-border payments?

Yes, and it is one of the strongest use cases for offshore merchants. Open banking’s direct bank-to-bank architecture reduces foreign exchange costs, accelerates settlement, and simplifies cross-border payment collection in markets with mature open banking infrastructure. UK and EU markets offer the most developed cross-border open banking capability currently.
