UK FCA Probe Puts PayPal, Visa and Mastercard Under Fresh Digital Wallet Scrutiny

The FCA’s investigation focuses on suspected anti-competitive conduct connected to how PayPal’s digital wallet is funded and used. According to the regulator, Mastercard, PayPal and Visa are being investigated under Chapter I of the UK Competition Act 1998, which covers agreements or concerted practices that may restrict competition. Mastercard and Visa are also being investigated under Chapter II, which concerns possible abuse of a dominant market position. Importantly, the FCA has emphasized that it has not reached any conclusion or made any finding that competition law has been breached, meaning the case is still at an evidence-gathering stage rather than a formal finding of wrongdoing.

The investigation became public after PayPal disclosed in its quarterly filing that it had received notices of investigation and related information requests from the FCA in March 2026. PayPal said the requests related to certain provisions in its contractual agreements with Visa and Mastercard regarding the funding and use of the PayPal digital wallet, and that it is cooperating with the regulator. Reuters also reported that Mastercard and Visa confirmed they were cooperating, with Mastercard saying it would work fully and transparently with the FCA and Visa saying the inquiry relates to contractual provisions around the PayPal digital wallet.

The timing of the probe reflects a broader regulatory shift in the UK payments market. Digital wallets are no longer a small convenience feature; they are becoming core payment infrastructure. The FCA and Payment Systems Regulator reported in 2025 that the share of card transactions made through digital wallets rose from 8% in 2019 to 29% in 2023. They also noted that digital wallets bring consumer benefits such as convenience, stronger security and potentially greater financial inclusion, but they heard concerns about the need for stronger competition among wallet providers and more room for new entrants. In other words, the FCA is not questioning digital wallets as a product category, but rather the market structure and contractual arrangements that may determine who can compete inside that category.

For PayPal, Visa and Mastercard, the commercial stakes are substantial. PayPal depends on card networks and linked bank funding to support its wallet ecosystem, while Visa and Mastercard benefit when card rails remain central to digital payments. If regulators find that certain contractual terms restrict competition, the companies could face pressure to modify agreements, change wallet funding rules or alter how payment options are presented to users. Even without penalties, the probe may force more transparency around how major payment firms structure partnerships in the digital wallet market.

The bigger market implication is that payment regulation is moving from traditional banking oversight into the architecture of digital finance. UK authorities are already examining the role of Apple and Google in mobile ecosystems, and this FCA probe adds PayPal, Visa and Mastercard to the same policy conversation. The key question is whether digital wallets will become an open layer that encourages multiple payment methods and new providers, or whether they will reinforce the power of existing card networks and dominant platforms. For investors, the case is worth watching because it could influence future margins, partnership models and competitive positioning across the global payments industry.
