UK PSR Enforces New Transparency Rules on Mastercard and Visa to Curb Rising Card Fees
By Lauren Towner · 31 July 2026

Quick Summary
The UK Payment Systems Regulator is tackling rising card fees by mandating that Mastercard and Visa provide absolute transparency on scheme and processing charges. This intervention ensures UK businesses can reconcile bills accurately, fostering competition and potentially lowering costs for consumers across the retail landscape.
How Will the PSR Card Fees Review Impact UK Businesses?
The PSR card fees review addresses a critical pain point for merchants: the lack of clarity in how card scheme fees are calculated and applied. By issuing a formal direction, the regulator is forcing a shift toward transparent billing practices that allow acquirers to understand every trigger and calculation behind a charge. This level of detail is designed to:
- Enable businesses to verify billing accuracy and avoid erroneous or unnecessary charges.
- Empower merchants to shop for deals on optional services by comparing clear cost structures.
- Reduce the inflationary pressure caused by fees that have historically risen faster than the standard cost of living.
These changes mean that the hidden costs of accepting payments will finally be brought into the light, allowing for better financial planning and vendor management for UK enterprises.
What New Requirements Must Mastercard and Visa Follow?
Mastercard and Visa are now subject to two primary directions aimed at strengthening market oversight. First, the Pricing Governance remedy requires both schemes to document their internal pricing logic, ensuring they consider the impact on the businesses that rely on their infrastructure. Second, a financial reporting mandate is in development, which will force the giants to disclose the profitability and performance of their UK-specific operations.
- 4-month deadline for implementing new pricing governance and internal record-keeping.
- 12-month window for full technical implementation of transparent acquirer billing.
- Ongoing financial reporting to provide the PSR with data for future regulatory interventions.
By front-loading accountability, the PSR ensures that pricing decisions are no longer made in a vacuum, but are instead subject to regulatory scrutiny and business-centric logic.
Why Is Regulatory Financial Reporting Necessary for Payments?
The introduction of Regulatory Financial Reporting marks a significant escalation in how the UK monitors global payment schemes. By requiring Mastercard and Visa to report on their UK card businesses, the PSR gains a data-driven lens into fee trends and profit margins. This prevents the schemes from leveraging their market dominance to implement opaque price hikes without justification. The regulator can now act swiftly if it detects anti-competitive behavior or excessive profitability that harms the wider economy.
FF NEWS TAKE:
This move by the PSR definitely moves the needle by challenging the duopoly's pricing power. For too long, card fees have been a 'black box' for merchants. By mandating transparency and pricing governance, the PSR is not just asking for fairness; it is building a framework for active enforcement. If Mastercard and Visa cannot justify their margins, they now face a regulator with the data to stop them.
