The Visa-Mastercard Interchange Fee Settlement: What It Means for Your Business

The Visa-Mastercard interchange fee settlement — the largest antitrust class action settlement in United States history at over $30 billion — is now reshaping the economics of credit card processing for millions of merchants. If you accept Visa or Mastercard (and nearly every business does), this settlement directly affects your costs. But the details matter, and most merchants do not fully understand what is changing, when it takes effect, and how to make sure they actually benefit.

Let us start with what the settlement is about. For decades, merchants have argued that Visa and Mastercard fix interchange fees — the fees merchants pay every time a customer uses a credit or debit card — at artificially high levels. Unlike a true market, where competition would drive prices down, interchange fees have historically only gone up. The class action lawsuit alleged that Visa and Mastercard conspired with their issuing banks to inflate these fees and prevent merchants from negotiating or steering customers to lower-cost payment methods.

The settlement, which received final court approval after years of legal challenges, includes several concrete provisions that will affect merchant costs over the next several years:

First, interchange rates on standard consumer credit card transactions are being reduced by at least 10 basis points (0.10 percent) for a period of at least five years. For a business processing $500,000 per year in credit card transactions, that translates to approximately $500 in annual savings on interchange alone. For larger businesses, the savings scale proportionally.

Second, a cap of 1.25 percent on standard consumer credit card interchange rates will be in effect for eight years. This cap applies to the base interchange rate for the most common transaction types. Premium cards, commercial cards, and certain specialized card categories may still carry higher rates, but the cap on standard consumer cards provides meaningful protection against future rate increases.

Third, the settlement expands merchant rights around steering and discounting. Merchants now have clearer legal standing to offer discounts for lower-cost payment methods (cash, debit, ACH) and to communicate the cost of payment methods to customers. This reinforces the legality of dual pricing and cash discount programs that many merchants are already using.

Fourth, Visa is making changes to its Compliance and Data Enhancement Program (CEDP), including the sunset of Level 2 data requirements effective April 2026. Level 2 data (which includes tax amounts, customer codes, and other enhanced transaction details) was previously required for certain business-to-business and government transactions to qualify for lower interchange rates. The sunset of this requirement simplifies processing for B2B merchants who previously had to invest in Level 2 data capture capabilities.

Now, here is where it gets practical. The interchange rate reduction does not automatically show up on your processing statement as a line-item discount. Whether you actually see the savings depends entirely on your pricing model.

If you are on interchange-plus pricing — where your processor passes through the actual interchange cost and adds a fixed markup — you will see the full benefit of the rate reduction. When interchange goes down, your cost goes down. This is the most transparent pricing model, and it is the reason Optec uses interchange-plus as our standard pricing structure.

If you are on tiered pricing (where transactions are categorized as qualified, mid-qualified, or non-qualified) or flat-rate pricing (like Square's 2.6 percent plus 10 cents or Stripe's 2.9 percent plus 30 cents), you may not see any benefit at all. In tiered pricing, the processor sets the tier rates and can absorb the interchange reduction into their own margin. In flat-rate pricing, the rate is fixed regardless of interchange — so when interchange drops, the processor's margin increases while your cost stays the same.

This is one of the most important takeaways from the settlement: merchants on interchange-plus pricing are the ones who benefit most. If you are currently on tiered or flat-rate pricing, the settlement is actually making your processor more profitable at your expense. The interchange reduction is going into their pocket, not yours.

Merchant buying groups are another development worth understanding. The settlement allows groups of merchants to band together and negotiate directly with Visa and Mastercard for lower interchange rates. While this provision is most relevant to large merchants and trade associations, smaller businesses can benefit by joining industry groups that negotiate collective rates. Your processor should be able to advise you on whether any buying group arrangements are available for your industry or transaction volume.

So what should you do right now? Here are five concrete steps every merchant should take in light of the settlement:

1. Request a copy of your current processing statement and calculate your effective rate. Your effective rate is your total processing fees divided by your total processing volume. This single number tells you what you are actually paying as a percentage of sales. If you do not know your effective rate, you cannot evaluate whether you are benefiting from the interchange reduction.

2. Confirm your pricing model. Ask your processor whether you are on interchange-plus, tiered, or flat-rate pricing. If they cannot give you a clear answer, that is a red flag. Your pricing model should be explicitly stated in your processing agreement and visible on your monthly statement.

3. If you are on tiered or flat-rate pricing, request a switch to interchange-plus — or compare processors. The settlement makes interchange-plus pricing even more advantageous than it already was. If your current processor will not offer interchange-plus, consider switching to one that will.

4. Review your statement for the interchange rate reduction. Once the reductions take effect, your interchange costs on standard consumer credit card transactions should decrease by at least 10 basis points. If you are on interchange-plus and you do not see the reduction reflected on your statement, ask your processor why.

5. Consider dual pricing or cash discounting. The settlement reinforces merchant rights to incentivize lower-cost payment methods. If processing costs are a significant expense for your business, a dual pricing program can reduce your effective rate to near zero on cash and debit transactions.

It is worth noting that the settlement does not affect debit card interchange, which is regulated separately under the Durbin Amendment. Debit interchange rates are already capped by federal regulation and are significantly lower than credit interchange. For merchants who process a high percentage of debit transactions, the settlement's impact on overall costs will be more modest. However, for businesses where credit cards dominate — restaurants, e-commerce, professional services — the rate reduction and cap are meaningful.

The settlement also has implications for how merchants evaluate new payment technologies. As interchange rates on standard credit cards decrease, the relative cost advantage of alternative payment methods like ACH, bank transfers, and cryptocurrency payments narrows. Merchants who adopted alternative payment methods primarily for cost savings may want to reassess whether the operational complexity is still justified given lower credit card interchange rates.

Looking ahead, the interchange landscape will continue to evolve. The settlement's provisions are time-limited — the 10 basis point reduction lasts five years and the 1.25 percent cap lasts eight years. After those periods expire, Visa and Mastercard could theoretically raise rates again, although the political and regulatory scrutiny of interchange fees makes significant increases unlikely. Merchants should use this window of lower rates to build their business with a processor that keeps them informed and positioned to benefit from market changes.

At Optec, every merchant is on transparent interchange-plus pricing, which means you automatically benefit from any interchange rate reduction — including those resulting from the settlement.
