Debit swipe-fee cap struck down: what changes for your fees, and when

A customer pays for a $50 dinner with a debit card from a big bank. Under the rule in place since 2011, the most that bank can collect on that sale is 24.5 cents, counting a 1-cent fraud-prevention add-on, according to the Federal Reserve. On October 26, a federal appeals court said the Fed set that cap the wrong way and threw it out.

Merchant groups are calling it a win. It may turn into one. But the ruling doesn’t lower anything on its own, and the next few months matter more than the headline.

What the court decided

A North Dakota truck stop called Corner Post sued the Fed over its debit fee rule, known as Regulation II. A district court sided with the truck stop in August 2025. On October 26, a three-judge panel of the Eighth Circuit Court of Appeals agreed unanimously.

The law behind the cap, the Durbin Amendment, tells the Fed to base it on what it costs a bank to authorize, clear and settle one particular debit transaction. The district court found the Fed had counted costs the law leaves out, including fixed costs, network processing fees, fraud monitoring and fraud losses. The appeals court agreed, focusing on fixed costs, the ones that don’t change with each extra sale. The Fed, the judges wrote, has to sort those costs out — “not just pick a number and hope it is close enough for government work.”

The court sent the rule back to the Fed to write a new fee structure. It didn’t set a new number.

The cap lost in court. Your debit fees haven’t changed yet. What happens next depends on the Fed and the courts, not this ruling alone.

Nothing moves on your statement yet

The ruling doesn’t take effect right away. By the court’s own footnote, it becomes effective seven days after the 45-day window to ask for a rehearing closes, or after a rehearing request is turned down. That puts it in mid-December at the earliest.

That date matters because the ruling throws out the cap without putting a new one in its place. When the district court struck down the rule last year, it paused its own order to keep debit fees from becoming, in its words, “a completely unregulated market”. A lower fee is the goal of the lawsuit. It isn’t guaranteed in the months before a new rule.

It may not be the last word, either. A Kentucky pizza shop brought the same challenge, and a federal court there sided with the Fed. That appeal, Linney’s Pizza, was argued in the Sixth Circuit on October 22 and is still waiting on a decision. If the two courts disagree, the Supreme Court is more likely to take the question.

The Fed already proposed a lower cap in 2023. On that same $50 sale, it would have dropped from 24.5 cents to 17.7 cents. The Fed never adopted it, and the court didn’t tell the Fed to use it.

Who it touches

The cap only ever applied to card issuers — banks or credit unions — that, with their affiliates, hold $10 billion or more in assets. Cards from smaller issuers, which includes most community banks and credit unions, were never capped, so this ruling doesn’t reach them directly.

Whether you’d ever see a change depends on how you’re priced. If your statement lists the card fees separately from your processor’s markup, a new cap would show up in those card fees. If you pay one flat rate for every card, a lower debit cost doesn’t reach you unless your processor passes it on.

And none of this changes what you can charge the customer. You still can’t add a surcharge to a debit card.

What to do now

1. 01Find the debit line on your statement. Pull your October statement and look at how debit sales are priced. If you can’t tell whether you pay the actual card fees or one blended rate, that’s your first question.
2. 02Ask your processor what happens if the cap changes. Does your debit pricing move automatically, or does it take a new agreement? Get the answer in writing.
3. 03Don’t sign anything for savings that don’t exist yet. No new cap has been written. A pitch built on “Durbin savings” this fall is selling a number nobody has.
4. 04Check back in mid-December. That’s when the ruling could take effect, unless the Fed asks the Eighth Circuit to rehear the case first. Its deadline for that is December 10.

Start with one statement

Pull your October statement this week and find what you paid on debit sales. When the Fed writes its new number, you’ll know right away whether it reaches you, and what to ask for if it doesn’t.
