The UK's Financial Conduct Authority (FCA) has launched a significant antitrust investigation into payment giants Mastercard, Visa, and PayPal.
This move isn't happening in a vacuum; it represents a major step in the UK's long-running examination of the digital payments market, particularly the power held by card networks. The probe focuses on suspected anti-competitive conduct linked to how PayPal's digital wallet is funded and used, examining potential restrictive agreements and abuse of dominance.
So, what led to this? First, the immediate trigger was the FCA's announcement on May 6, 2026, which the agency explicitly linked to PayPal's recent financial disclosures. This builds on years of work by the UK's Payment Systems Regulator (PSR), which has already concluded that Visa and Mastercard face weak competitive constraints, allowing them to raise fees significantly without losing business.
Second, a key catalyst for this regulatory focus was Brexit. After the UK left the European Union, EU-imposed caps on interchange fees no longer applied. In 2021, Visa and Mastercard increased certain cross-border fees fivefold, which drew sharp criticism from businesses and politicians and triggered the PSR's market reviews.
Third, the investigation also looks back at the very structure of the relationship between these companies. Agreements made around 2016 between PayPal and the card networks, which reduced PayPal's practice of 'steering' users toward cheaper payment methods in exchange for incentives, are now under scrutiny as potentially anti-competitive.
In essence, the FCA is now using its direct enforcement powers under the Competition Act 1998 to investigate specific conduct that the PSR's broader market studies have framed as problematic. While the initial market reaction was muted and the direct financial risk appears small for now, this probe signals a serious regulatory challenge to the established economics of digital wallets in the UK.
