FCA probes Paypal, Mastercard and Visa competition

The UK’s Financial Conduct Authority has opened a competition investigation into PayPal, Mastercard and Visa, examining whether commercial arrangements linked to PayPal’s digital wallet may have restricted competition in the payments market.

FCA probes Paypal, Mastercard and Visa competition

The inquiry is being conducted under the Competition Act 1998. PayPal, Mastercard and Visa are being investigated under Chapter I, which covers agreements and concerted practices that may prevent, restrict or distort competition.

Mastercard and Visa are also being examined under Chapter II, which concerns potential abuse of a dominant market position.

At this stage, the regulator has stressed that it has reached no conclusions and made no findings of wrongdoing. The investigation remains an evidence-gathering exercise.

Contractual Terms at the Centre of the Case

The case became public after PayPal disclosed the matter in a filing with the US Securities and Exchange Commission. The company said it had received notices of investigation and information requests from the FCA in March 2026.

According to PayPal, the requests relate to provisions in its contractual agreements with Visa and Mastercard concerning the funding and use of the PayPal wallet.

In practical terms, the FCA appears to be looking at whether the rules governing how consumers load and use PayPal may have affected competition between cards, wallets, bank payments and alternative funding methods.

For the UK payments sector, this is significant. Digital wallets are no longer a niche layer on top of card payments. They are a mainstream checkout option, a consumer interface, and an increasingly important point of control in the payment chain.

Why Card Networks Matter

Visa and Mastercard sit at the heart of the global card infrastructure, while PayPal remains one of the best-known online wallet brands. Any agreement between such firms can shape the economics of payment acceptance, consumer choice and merchant costs.

The FCA’s interest reflects a wider regulatory concern: whether powerful payment intermediaries can influence market access or pricing through contractual structures that are difficult for consumers, merchants and smaller competitors to see.

The probe also matters beyond retail e-commerce. Many financial trading platforms and brokers use the same payment rails for client funding. Visa, Mastercard and PayPal are commonly offered alongside bank transfers by firms serving FX and CFD customers.

Although the FCA investigation does not currently alter deposit options for traders, it highlights the extent to which “everyday” payment systems underpin wider financial infrastructure.

Part of a Broader Regulatory Pattern

The UK action comes amid growing international scrutiny of large payment firms. In the US, Visa and Mastercard have faced long-running antitrust litigation over merchant fees, while regulators have also shown increasing interest in access to payment services and the conditions attached to them.

For now, the FCA has not alleged a breach. But the investigation is a clear signal that digital wallet economics, card network power and contractual restrictions are moving higher up the competition agenda.

If the regulator ultimately identifies concerns, it could issue formal objections before reaching any final decision.

Until then, PayPal, Mastercard and Visa will be under pressure to demonstrate that their wallet arrangements support, rather than suppress, effective competition in UK payments.
