Visa and Mastercard Could Break the Rules That Made Them Billions

Visa and Mastercard are reportedly nearing a landmark settlement with U.S. merchants to resolve a two-decade legal dispute, proposing to reduce credit-card interchange fees by approximately 0.1 percentage point over several years and relax 'honor all cards' rules. This agreement, if approved, would allow merchants to decline specific high-cost premium rewards cards and offer greater flexibility for surcharging, potentially impacting the profitability of card issuers and altering consumer credit usage. For investors, this development signals a significant shift in the multi-trillion-dollar U.S. payments ecosystem, balancing network profitability with merchant costs and regulatory pressures, though separate litigation from large retailers will continue.

Analysis

Visa (V) and Mastercard (MA) are reportedly nearing a significant settlement in a two-decade antitrust dispute with U.S. merchants. The proposed agreement includes a reduction in credit-card interchange fees by approximately 0.1 percentage point over several years, from the current 2-2.5% range, and would relax "honor all cards" rules, allowing merchants to decline specific high-cost premium rewards cards. This also grants merchants renewed flexibility for surcharging.

This development follows a prior settlement attempt in early 2024, which offered a smaller 0.07 percentage point reduction and was rejected by the court, underscoring persistent pressure on fee structures. Interchange fees are a substantial revenue source, with Visa and Mastercard issuers collecting an estimated $72 billion in 2023, according to the Nilson Report. The settlement aims to balance network profitability with merchant costs and regulatory scrutiny.

The ability for merchants to decline premium rewards cards could significantly alter consumer spending habits and impact the profitability of bank-issued rewards programs, which are central to their profit engines. While offering relief to merchants, this carries a risk of slower sales for stores that deter high-spending cardholders. Importantly, this agreement would not conclude all litigation, as large retailers continue to pursue separate cases for damages.

Key Decisions for Investors

• Monitor the final approval and implementation details of the settlement, as the 0.1 percentage point fee reduction impacts a substantial revenue pool for V and MA.
• Evaluate the potential shift in consumer behavior and its effect on card network transaction volumes and the profitability of bank-issued rewards programs due to relaxed "honor all cards" rules.
• Assess the ongoing legal and regulatory landscape, as separate litigation from large retailers indicates continued pressure on interchange fees and potential for future adjustments.
