Why Debit Card Rewards Disappeared (and Where They Survived) 2026

Key Takeaways

The Durbin Amendment cut the debit interchange fee for large banks roughly in half starting in 2011 — from an unregulated average of about 44 cents to a capped 21 cents plus 0.05% of the transaction — and big-bank debit rewards mostly disappeared with that revenue.
A specific exemption for banks and credit unions under $10 billion in assets is why debit rewards survived at all: exempt issuers still average roughly double the interchange fee of capped large banks (51 cents vs. 23 cents, per 2024 Fed data).
Discover's national cashback debit push is a genuine strategic outlier, not a return to the old model — Discover is large enough to fall under the cap, so its rewards program is a different bet than the pre-2011 big-bank programs the cap effectively ended.

Quick answer

Debit rewards mostly vanished at large banks after 2011 because the Durbin Amendment capped the fee banks earn on each debit swipe, cutting large-issuer interchange revenue roughly in half — the same revenue that had been funding those rewards programs. A carve-out for institutions under $10 billion in assets is the entire reason credit unions and smaller banks still offer cashback debit today, and it's why a handful of large exceptions (like Discover) are genuinely notable rather than a sign the old model returned.

The fee that funded the rewards

Every time you swipe a debit card, the merchant's bank pays the cardholder's bank a small fee — the interchange fee — as part of processing the transaction. Before 2011, this fee was unregulated and averaged around 44 cents per transaction for large banks. That revenue, multiplied across billions of debit transactions a year, was substantial enough to fund real rewards programs: cashback, bonus categories, the kind of debit perks that felt closer to a credit card's rewards structure.

The Durbin Amendment, enacted as Section 1075 of the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act and implemented by the Federal Reserve's Regulation II in 2011, capped that fee for issuers with $10 billion or more in total assets at 21 cents plus 0.05% of the transaction (plus a small additional allowance for fraud-prevention costs). For a large bank, that's roughly a 50% cut in per-swipe revenue, applied essentially overnight.

Where the interchange revenue actually went

Interchange fees are split between funding fraud prevention, network costs, and — before the cap — rewards programs. Once the cap roughly halved that pool for large banks, rewards programs were the most discretionary line item to cut, and most large banks cut them.

The exemption that kept rewards alive

The Durbin Amendment's cap only applies above the $10 billion asset threshold. Banks and credit unions below it are exempt and can still charge — and collect — the higher, uncapped fee. Federal Reserve data from 2024 shows the gap this exemption created is still very real: exempt issuers averaged 51 cents per transaction, versus 23 cents for capped large issuers — more than double.

That surviving revenue is the entire reason cashback and rewards debit accounts still exist at community banks and credit unions today. It isn't a coincidence that the debit rewards landscape skews toward smaller institutions; it's a direct, traceable consequence of where the fee cap does and doesn't apply.

Why Discover is the interesting exception

Discover Bank is large enough to fall under the interchange cap, which makes its national Cashback Debit push — including a first-ever national TV ad campaign for a banking product — genuinely notable rather than a sign the pre-2011 model quietly returned. A large, capped issuer choosing to fund real rewards (1% cash back on up to $3,000 in monthly debit purchases) despite the lower per-swipe revenue suggests the program is more likely justified by customer acquisition and account-relationship value across Discover's broader banking and lending business than by interchange economics alone — a different bet than what big-bank debit rewards used to be.

Did the trade-off actually help consumers?

The stated goal of the Durbin Amendment was for merchants to pass their interchange savings through to consumers as lower prices. The revenue loss to issuers, and the resulting cut to debit rewards, is clearly documented. The pass-through side is much less settled — independent research after the rule took effect found limited and inconsistent evidence that merchants actually lowered prices in response. In other words: the cost to consumers (fewer debit rewards) is well established; the promised benefit (lower prices) is a genuinely more disputed question.
