Congress Takes Aim at Card Network Fees
Every time a customer swipes a credit card at a grocery store or gas station, the merchant pays a fee – typically between 1.5% and 3.5% of the transaction – split between the card-issuing bank and the payment network processing the transaction. For decades, Visa and Mastercard have operated as the two dominant forces controlling those fees, and for just as long, retailers have been complaining about it. Now, that complaint has a congressional audience.
Lawmakers on both sides of the aisle have begun pushing for federal intervention into what the retail industry calls an unfair and opaque fee structure. Bipartisan pressure is mounting around legislation that would require large credit card networks to allow merchants to route transactions through competing networks – a structural change that proponents argue would introduce real competition into a market they say has operated like a duopoly for too long.
What the Legislation Actually Proposes
The Credit Card Competition Act, which has been introduced in various forms over recent congressional sessions, is back in focus. The bill would require banks with more than $100 billion in assets to offer merchants at least two network routing options for credit card transactions – one of which could not be Visa or Mastercard. The goal is to give retailers leverage to shop for lower processing costs, similar to how the Durbin Amendment worked for debit cards after the 2010 Dodd-Frank financial reform law.
Supporters of the legislation, including a broad coalition of retail groups and small business associations, argue that the current system forces merchants to accept whatever fees the dominant networks set. Because Visa and Mastercard together handle the vast majority of U.S. credit card transactions, merchants have little practical ability to refuse their cards without losing customers. That structural imbalance, retailers say, has allowed interchange fees to grow steadily over time without competitive pressure keeping them in check.
The Banking Industry Pushes Back Hard
Opposition to the bill is well-organized and well-funded. Banks and credit unions argue that interchange fees are not simply profit – they fund the rewards programs, fraud protection systems, and credit infrastructure that cardholders rely on. Cut the fees, they warn, and issuers will scale back the travel points, cash-back offers, and zero-liability fraud protections that have become standard features of consumer credit products.
Visa and Mastercard have each made similar arguments in their public statements and lobbying efforts. Both companies frame themselves as neutral infrastructure providers whose fee structures reflect the real costs of operating secure, global payment networks. They also point to ongoing investments in fraud detection and dispute resolution as services that ultimately benefit both merchants and consumers.
The debit routing precedent is a contested piece of evidence in this debate. Retail groups cite the Durbin Amendment as proof that routing competition lowers merchant costs. Banking advocates counter that the debit experience actually resulted in the elimination of free checking accounts and reduced benefits for lower-income customers – a redistribution of costs rather than a genuine savings event. Neither side’s version of the debit story is clean.
What makes the credit card version of this fight more complicated is the rewards dimension. Debit cards carried minimal loyalty benefits, so dismantling debit interchange had limited consumer backlash. Credit card rewards programs, by contrast, are deeply embedded in consumer behavior – particularly among higher-income cardholders who have built travel and lifestyle routines around points accumulation. Any legislation that visibly degrades those programs will face political exposure, regardless of the policy merits.
Merchants Frame This as a Cost-of-Living Issue
Retail groups have worked to shift the framing of swipe fee debates away from business-versus-bank and toward consumer pricing. Their argument: merchants, especially small businesses operating on thin margins, pass interchange costs directly into product prices. Because these fees apply to every credit transaction, they function as a hidden tax that every consumer pays, whether they use cash or credit.
Independent grocers and gas station operators have been among the loudest voices making this case on Capitol Hill. For high-volume, low-margin businesses, credit card fees represent one of the largest controllable operating expenses after labor and inventory. A gas station processing several hundred thousand dollars a month in credit card sales can pay tens of thousands of dollars annually in interchange alone – a number that concentrates the mind of a small business owner in a way that abstract policy language does not.
Where This Stands Politically
The Credit Card Competition Act has attracted co-sponsors from both parties, which gives it more credibility than most financial reform proposals manage. Senator Dick Durbin, the Illinois Democrat who authored the original debit routing provision, has been a consistent champion. Republican co-sponsors have framed the bill in terms of free-market competition rather than consumer protection regulation – an ideological repositioning that makes it more viable in a divided Congress.
Still, the bill has stalled before and could stall again. The financial services industry has considerable influence over members of the Senate Banking Committee and the House Financial Services Committee, the two panels with jurisdiction over any card regulation. Lobbying disclosures show that Visa, Mastercard, and their banking allies spend substantial sums every year maintaining relationships across both chambers. That investment reflects how seriously these companies treat legislative threats to their fee revenue.
The timing of the current push matters. With consumer inflation still a live political issue, any argument that connects corporate fee structures to household costs lands differently than it might in a benign economic environment. Retailers have been deliberate about keeping that connection visible in their congressional testimony and media campaigns. The question now is whether enough lawmakers conclude that the political benefit of acting outweighs the fundraising risk of crossing the financial services sector – and that calculation has defeated similar efforts before.
