Merchants Push Back Against Visa-Mastercard Swipe-Fee Settlement

A coalition of close to 1,000 US merchants has filed formal objections urging a federal judge to reject the proposed class-action settlement in MDL 1720, the two-decade antitrust battle over Visa and Mastercard interchange fees. The scale of opposition puts the deal's structural adequacy — not just its dollar value — squarely before the court.

Why this matters

If the court heeds merchant objections and rejects the settlement, the fundamental economics of card acceptance and interchange fee-setting could face genuinely structural reform rather than another temporary fix.

Merchants Push Back Against Visa-Mastercard Swipe-Fee Deal

A substantial coalition of US merchants has filed formal objections urging a federal judge to reject the proposed settlement in the long-running antitrust litigation over Visa and Mastercard interchange fees — a case that has wound through the courts for nearly two decades and represents one of the most consequential payment-industry legal battles in American history.

According to reporting by Finextra, close to 1,000 merchants have submitted objections to the deal. The scale of the opposition is significant: when the businesses most directly affected by a settlement mobilise in such numbers to oppose it, courts are obliged to take those concerns seriously before granting final approval.

Background: The Interchange Fee Wars

The litigation — formally known as MDL 1720, consolidated in the Eastern District of New York — centres on multilateral interchange fees, the per-transaction charges that card networks set and that flow from merchant-side banks to card-issuing banks every time a consumer swipes or taps a Visa or Mastercard credit card. For most merchants, particularly smaller retailers and hospitality businesses operating on thin margins, interchange is one of their largest operating costs after labour.

Critics of the current interchange system have long argued that the fee-setting process is inherently anti-competitive: because Visa and Mastercard operate as the dominant four-party networks and set default interchange rates collectively, individual merchants have no meaningful ability to negotiate them down. The lawsuit alleged that this arrangement constituted a violation of US antitrust law.

A previous settlement attempt — a $7.25 billion agreement reached in 2012 — was ultimately rejected by an appeals court in 2016, with objectors arguing it failed to adequately represent merchants who had opted out. The current proposed settlement represented a further attempt to resolve the dispute, including provisions intended to modestly constrain interchange rate increases for a defined period.

Why the Opposition Matters

The breadth of the merchant opposition now before the court raises a pointed question: does the proposed deal actually change anything meaningful in the structural economics of card acceptance?

When nearly 1,000 merchants — the very plaintiffs a class settlement is designed to serve — formally ask a court to reject it, the settlement's adequacy becomes the central question, not a footnote.

From an editorial standpoint, that tension is the heart of the matter. Class-action settlements in antitrust cases require judicial approval precisely because class members — here, an enormous and heterogeneous group of US merchants — cannot individually negotiate their terms. The court acts as a proxy guardian of their interests. A wave of objections of this scale will likely force the presiding judge to conduct a rigorous adequacy analysis before any approval is granted.

Structural Loopholes and Merchant Concerns

While the precise legal arguments filed by the objecting merchants could not be independently verified by Fin Desk at publication — the primary court filings were not directly accessible — the nature of interchange settlement disputes follows a well-established pattern. Merchant coalitions in prior rounds of this litigation have consistently argued that temporary rate caps are easily circumvented through the introduction of new card categories or fee types not covered by settlement language, and that injunctive relief provisions tend to expire before any durable competitive change takes root.

Whether those specific arguments feature in the current objections is unconfirmed. What is clear is that the sheer number of objectors suggests the merchant community does not regard the proposed terms as a satisfactory resolution of their underlying competitive grievances.

What Comes Next

The federal judge overseeing the case will now need to weigh the objections against arguments from settlement proponents — including class counsel, who negotiated the deal — that the agreement represents a reasonable outcome given litigation risk and the likelihood of a prolonged appeals process if the case continues.

For the payments industry, the stakes extend well beyond the immediate parties. A rejected settlement would send the litigation back into active proceedings, prolonging legal uncertainty for Visa and Mastercard at a moment when both networks are already navigating regulatory scrutiny in multiple jurisdictions — including parallel debates in the European Union over interchange caps under the Interchange Fee Regulation, and ongoing UK Payment Systems Regulator reviews of cross-border card fee increases.

Merchants, regulators and payments-industry observers on both sides of the Atlantic will be watching the Eastern District of New York closely. The outcome could inform arguments about whether market-based litigation, as opposed to direct regulatory intervention, is a viable mechanism for restructuring the economics of card acceptance.
