The High Court rejected the legal suit by Visa, Mastercard, and Revolut, holding that financial regulators in the UK have strong powers to intervene in payment pricing, even without explicit fee-cap language in the legislation.
On 15 January 2026, the UK High Court dismissed a legal challenge brought by Visa, Mastercard, and Revolut against the Payment Systems Regulator (PSR), confirming the regulator’s authority to intervene in the pricing of cross-border card transactions. The decision clears the way for the PSR to move forward with potential caps on interchange fees charged on online card payments between the UK and other countries.
The case stemmed from fee increases introduced by Visa and Mastercard after Brexit. When the UK left the European Union, EU-mandated caps on cross-border interchange fees no longer applied. The card networks subsequently raised fees on UK-to-EU and EU-to-UK e-commerce transactions, prompting concerns from merchants and policymakers about higher costs and limited competitive pressure. The PSR argued that the increases were excessive and that the market was not functioning effectively. Therefore, the UK regulator proposed a cap on cross-border interchange fees charged by major payment networks to avoid businesses losing their competitive edge due to overpaying.
Visa, Mastercard, and Revolut challenged the regulator in court, contending that the PSR did not have the legal mandate to impose or consult on price caps and warning that such intervention could harm competition and innovation. After thorough consideration, the High Court rejected those arguments, finding that the PSR’s statutory powers extend to pricing measures where necessary to address market failures in payment systems.
The ruling is significant for payment providers because it confirms that regulators can directly shape revenue structures in card payments. Interchange fees represent an important income stream for card schemes, issuing banks, and many fintechs, particularly those with low or zero consumer fees. Any cap introduced by the PSR could put pressure on margins and force providers to reassess pricing models, partnerships, or value-added services.
For merchants, the judgment is widely seen as a positive development. Cross-border interchange fees are ultimately borne by businesses through acquiring banks, and the PSR has estimated that elevated fees cost UK merchants hundreds of millions of pounds each year. Lower fees could reduce payment acceptance costs, particularly for online retailers and small businesses that rely heavily on card payments.
Consumers may also benefit indirectly. While interchange fees are not paid by shoppers directly, they influence retail pricing. Reduced costs for merchants could ease upward pressure on prices or support greater investment in customer experience and digital commerce.
More broadly, the decision reinforces a tougher regulatory stance on payment systems in the UK’s post-Brexit landscape. It signals that card networks and fintechs operating in the market should expect closer scrutiny of fees and practices, aligning the UK with a global trend toward tighter oversight of payments infrastructure.
With the legal challenge resolved, attention now turns to the PSR’s next steps, including the level and timing of any fee caps that could reshape the economics of cross-border card payments in the UK.
