Visa and Mastercard Interchange Settlement Case Study
21 years of antitrust litigation produced a settlement that cuts swipe fees and, more consequentially, rewrites who controls card acceptance. I read the order, separated it from the settlement everyone confuses it with, and traced what it does to merchants, to the credit card rewards programs interchange pays for, and to the cardholders who earn from them.
Does this settlement actually change merchant economics?
Coverage framed the deal as a swipe fee win for small business. That framing is testable. A price cut that expires in five years and a set of acceptance rights a corner store cannot realistically use are very different kinds of relief, and the difference decides who actually benefits. I wanted to know which lever the settlement really pulls, and where the second-order effects land.
The analysis
After 21 years of litigation, a swipe-fee settlement would change how merchants accept Visa and Mastercard. What it does, and what it means for the small businesses at the center of the case.
The analysis below stays neutral and sourced. Where I draw my own conclusion I say so in the first person, so opinion is never mistaken for a finding.

Each point is worked through in the sections that follow, with sourcing in the methodology.
Where the fee actually sits
Every card swipe moves through four parties. Interchange is the fee in the middle, and the one the lawsuit is about.
A 21-year fight
The case dates to 2005. This is the third attempt at these rule changes a judge will approve, after earlier versions were rejected in 2016 and 2024, and it is not over yet.
What the deal does, and which cards it reaches
Four changes, two on price and two on what merchants are allowed to do. The control changes may matter more than the price cuts.
The combined average effective credit interchange rate across Visa and Mastercard drops by 0.10% for five years. Large merchants who negotiated custom rates get a pro rata reduction too. Their own rate comes down by the same proportion rather than being reset to a common number, so a merchant already paying below the average still sees a cut and keeps the advantage it had. The prior settlement gave them nothing.
Posted interchange on standard consumer credit cards is capped at 1.25% for at least eight years, which the court called a 0.62% cut from today's average. The other posted credit rates, meaning premium consumer and commercial cards, are not cut at all. They are frozen: for five years Visa and Mastercard cannot set them above wherever they stood on March 31, 2025, though either may go lower by choice. So the standard consumer card is the one category whose posted rate is actually cut, while the rest of the ladder only gets a ceiling. What those March 2025 levels are is not one number, and it matters enough to set out in full.
Visa and Mastercard’s honor-all-cards rule is effectively repealed, so a merchant can take standard cards while refusing pricier premium ones, or consumer while refusing commercial. But honor-all-issuers survives, so within a category it accepts, a merchant must still take every bank's card. It can drop a card type, not a single issuer.
Merchants may surcharge by card brand or product up to 3%, capped at the card's cost of acceptance, and steer or discount by type. The prior deal's tighter 1% limit for merchants taking Amex is removed.
Where the relief landsThe cut lands somewhere uncomfortable. The one tier whose posted rate is actually reduced is the entry-level one, the classification issuers use for secured, student, and basic bank cards, while the tiers carrying the rewards products are only frozen. That is about which cards get the ceiling, not about who the settlement helps overall, since the effective-rate cut and the rule changes reach every category. What I would not do is call that entry-level tier subprime. It is a product classification, not a credit grade, and plenty of prime cardholders carry a basic card from their bank or credit union. The asymmetry is still worth stating plainly, and what I would measure before going further is issuance and volume mix by tier against cardholder credit profile. No filing in this case reports it, so this is structural, about the tiers, rather than a claim about who holds them.
What it means for small businesses
The same terms affect small and large merchants differently. The new control rights are worth more to a large chain than to a corner store.
What improves
- The 0.10% cut and the 1.25% consumer card cap lower the posted rates a small merchant cannot negotiate down on its own.
- The right to surcharge or steer gives, for the first time, a way to push back on premium cards, the priciest to accept.
- If the deal is approved, the relief is automatic. A small merchant files no claim to receive it.
What falls short
- Declining a premium card means declining a paying customer at the counter, a risk a small shop can rarely take.
- Surcharging carries its own friction, including customer pushback, signage rules, and a patchwork of state law. Many small merchants will not use it.
This is the one place the settlement lands unevenly by geography. The terms are national: the same caps, the same acceptance rights, every state. But surcharging is governed by state law on top of that, and it is banned outright in Connecticut, Maine, Massachusetts, and Puerto Rico. A merchant there gains a right the settlement grants and its own state forbids.
Elsewhere the constraint is softer but still real: caps that differ by state, signage and disclosure rules that differ, and a debit carve-out throughout. So two merchants of the same size, in the same category, with the same customers, can end up with different tools depending on which state they trade in. Nothing in the order addresses that, because it is not the court’s to address.
What does not vary is the price. Interchange is set by card tier, merchant category, and whether the card was present, not by where the store is, so there is no high-cost-city or low-cost-city version of the rate.
Where the parties stand
This is not a clean Visa and Mastercard versus merchants split. Both networks and their allies back the deal, and a large bloc of merchants opposes it.
Calls it a win
Framed as meaningful, flexible relief for merchants of all sizes, and described by one trade group as a win for Main Street. Networks emphasize the added flexibility for merchants and the chance to end a case running more than two decades.
Says it falls short
They cannot leave. The class is mandatory with no right to opt out, so objectors are bound by a release they reject, and Walmart's counsel called that structure probably unconstitutional at the April hearing. That is a procedural objection rather than an economic one, and it is why NACS has signaled it will appeal to the Second Circuit if final approval is granted. Their economic case is the incidence argument by merchant segment.
Who objected, and why it mattersThe alignment is the surprise. When the intended beneficiaries object, and nearly 40 objection letters is not a fringe, the remedy is probably mispriced against what the class gave up. Merchants are not comparing this relief to nothing, they are comparing it to a release that binds them with no opt-out. That reframes the objections from ingratitude to arithmetic.
The pressure on credit card rewards programs
The pricing and acceptance changes reach beyond merchants to the rewards programs, and the banks behind them, that American consumers have built their spending around.
Rewards are paid for out of card revenue, and that revenue has two big lines: interchange, and interest on revolving balances. Which one dominates depends on the cardholder. Someone carrying a balance generates interest. Someone who pays in full every month generates almost none, so their card earns mostly interchange, and that is precisely the customer premium and travel cards are built to attract. So for the rewards segment specifically, the richer the rewards, the higher the swipe fee, and the model has always depended on merchants having to accept the card to reach that customer. This settlement compresses that funding on two fronts at once. The 1.25% cap applies to standard consumer credit, where most everyday cash back cards sit, and the widened premium-to-standard gap plus the right to refuse the premium category puts the top of the market in play for the first time. That is not a premium-tier problem, it is pressure on the revenue line the rewards segment leans on hardest. The same order also loosens the honor-all-wallets rule, letting a merchant accept some digital wallets, such as Apple Wallet, while declining others, such as Google Wallet or Samsung Wallet.
The Apple Card is a useful stand-in. It is a premium, rewards-driven card whose economics lean on interchange. It sits at the premium end, where the acceptance risk is sharpest, but the same interchange that funds it funds the cash back card in everyone else’s wallet, so pressure at the top and a cap at the bottom squeeze the same line. Used here as a public illustration only, not as a claim about Apple's plans.
What it means for cardholders
Almost every account of this settlement stops at the merchant. But if rewards funding is what the settlement compresses, then everyone who earns cash back, miles, or points is downstream of it, and the people who organize their spending around premium rewards are the most exposed.
Who is least exposed
- Anyone carrying a standard Visa or Mastercard consumer credit card. That category is the one the settlement caps and protects, and it is the category merchants keep accepting.
- Debit and cash users, who sit outside the credit interchange question entirely.
- Shoppers at large merchants, who are the least likely to see a category refused at the register.
Who is most exposed
- Points and miles optimizers, whose whole strategy is to route spend onto the highest-earning premium cards.
- Travelers holding cards where the value is in transfer partners, lounge access, and travel credits, all funded from the same pool.
- Anyone holding a premium card as their only card, who now faces a category a merchant is permitted to decline.
Who else is exposed
Bottom line
This settlement pairs a temporary, capped price cut with a more durable change in who controls card acceptance. Small merchants get modest price relief and new rights they will struggle to use. Large merchants gain leverage they mostly already had, plus a reason to keep fighting.
How narrow the relief isThe relief is narrower than the headline suggests. Only the standard consumer tier gets a ceiling set below today’s posted rates, while premium and commercial are held at theirs. And nothing here, or in the discount programs that already existed, lowers a rate because a business is small. Where pricing does turn on volume, it rewards scale.
What this signals for rewardsFor rewards, this is the first real sign that universal acceptance cannot be taken for granted, and the people most exposed are the ones who built a strategy around premium cards. If issuers recover the lost interchange, the annual fee and the interest rate are the visible instruments. Devaluation is the invisible one, and it is the one I would expect first, because it leaves every advertised term intact.
What I would build firstIf I worked at a network or a premium issuer, the first thing I would build is not a rewards response, it is a measurement plan. Adoption of category declination is the variable everything else depends on, and nobody has it yet. The second thing I would do is stop describing acceptance as universal in any internal model that projects past 2026.
What is still unsettledFinal approval and appeals are still ahead. The swipe-fee fight has narrowed, but it is not over. Whatever the outcome, interchange at Visa and Mastercard will stay under pressure from regulators, merchants, and the courts.
Preliminary approval was granted by Judge Brian Cogan in the Eastern District of New York.
The limits of the analysis
It is preliminary, and preliminary is not final. A notice-and-comment period is outstanding, final approval has not issued, and the National Association of Convenience Stores has said it will appeal to the Second Circuit if it does. Two earlier versions of this deal were rejected outright, so a third revision is not unthinkable. I dated every claim rather than writing as if the outcome were settled, and the review date in the summary is the honest expiry on all of it.
Surcharging looked like the answer and is not. My first read treated the surcharge right as the merchant's real lever. The Federal Reserve steering evidence changed my mind, and I rewrote the conclusion rather than hedging the original. It is the one claim here I reversed outright, and I flag it instead of repeating the reasoning because a reader is entitled to know which conclusions survived contact with the data and which did not.
I can see posted rates, not paid rates. Interchange schedules are published. The rates large merchants actually negotiate are not, and neither are the acquirer markups layered on top. So when I say the relief compounds leverage a national chain already had, that is inference from the pro rata mechanism in the terms rather than a measurement of anyone's effective rate. It is also why the fee split on this page stops where it does. I can source the interchange share and not the network and acquirer split behind it. Nobody outside those contracts can, which is worth remembering whenever a party to this case quotes an average.
One load-bearing number is single-sourced. The estimate that standard consumer is roughly 10% of Visa and Mastercard consumer credit volume comes from one payments consultancy reading the settlement. It is not in the court’s order, which states no category volume split at all, and a fair amount of the tier argument leans on it. If that share is materially wrong, the claim that the capped tier is a thin slice of the market weakens with it. I marked it as an analyst estimate everywhere it appears rather than promoting it to a finding, and it is the first thing I would verify against network volume disclosures.
Card tiers came from benefits reporting, not the settlement. The settlement defines the tiers by product name. It does not say which card sits in which tier, because that assignment is made by the issuer and published in each card’s guide to benefits. So the named cards come from published benefits reporting, issuers can and do move products between tiers, and any card whose tier I could not document is simply absent. The same applies to the annual fees quoted here. Several premium fees moved during 2025, so treat them as of this review date rather than as current pricing. Treat that column as illustrative of the tiers as of this review date rather than a register of them.
This is desk research. Every claim here rests on filings, published rate schedules, regulator research, and reporting. I did not interview a merchant about whether it would actually decline a premium card, an issuer about how it would recover capped interchange, or a cardholder about what a devaluation would change. The behavioral questions this analysis keeps arriving at are the ones documents cannot answer, and I would rather name that than imply the record settles them.
The pricing analysis stops at credit. Debit is not absent from this page. It supplies the closest completed precedent through the Durbin cap, it is carved out of the surcharging right, and the class itself covers merchants who accepted either. What I did not do is analyze debit’s own economics under this settlement, because debit interchange already runs on a separate regulated track and a separately represented group of debit plaintiffs objected on their own terms at the April hearing. That is a second analysis, not a paragraph in this one.
