At the center of the controversy is the Durbin Amendment, a provision included in the 2010 Dodd-Frank financial reform law. The amendment placed limits on the interchange fees that large banks can collect when consumers use debit cards. Supporters claimed the measure would help retailers by reducing transaction costs. Opponents warned it represented government price controls that would distort the market and ultimately create unintended consequences.
Those warnings may now be coming back into focus.
Every time a consumer uses a debit card to make a purchase, multiple parties are involved in processing the transaction. Traditionally, networks such as Visa and Mastercard facilitate those payments, while banks receive interchange revenue tied to each purchase.
The Durbin Amendment capped certain fees associated with those transactions when they travel through outside payment networks. However, industry observers note that the law does not operate the same way when a bank owns the network handling the transaction itself.
That distinction has attracted renewed attention following Capital One’s acquisition of Discover Financial Services. The deal did more than expand Capital One’s credit-card business. It also gave the company control of Discover’s payment network infrastructure, creating a model that other banks may find attractive.
Reports indicate that JPMorgan Chase, Bank of America, Wells Fargo, and PNC Financial Services Group have held discussions regarding a potential acquisition involving Fiserv’s Star debit network. Analysts have estimated such a deal could carry a price tag reaching into the billions of dollars.
The appeal is obvious to many in the banking industry.
Payments consultant Eric Grover did not mince words when discussing the potential benefits.
“I’m a huge fan of banks buying their own debit networks to escape Durbin.”
Others have been equally direct about what ownership of a payment network could mean.
Holland & Knight partner Eamonn Moran summarized the situation in a single sentence:
“Own the network and the cap disappears.”
Those remarks have fueled concerns among lawmakers, merchants, and consumer advocates who believe large financial institutions may be searching for a legal pathway around regulations that have governed debit transactions for more than a decade.
At the same time, reports suggest some banks have grown cautious about pursuing such acquisitions because of the political fallout they could trigger. Any move viewed as an attempt to bypass federal regulations would likely draw scrutiny from regulators, members of Congress, and retail groups that have long supported interchange-fee restrictions.
The hesitation itself has become part of the story.
According to reporting on the matter, several institutions are weighing whether the benefits of owning a payment network outweigh the public-relations battle that could follow. Critics argue that if the strategy were easily defensible, banks would have little reason to keep discussions behind closed doors.
The debate arrives as legal challenges continue to chip away at portions of the Durbin regulatory framework. In 2025, a federal judge in North Dakota ruled that the Federal Reserve exceeded its authority when implementing aspects of the original swipe-fee regulations, a decision that reignited questions about the government’s role in setting transaction fees.
For free-market advocates, the development serves as another reminder that government intervention often creates incentives for companies to search for workarounds rather than solving underlying market issues.
Meanwhile, some of the largest players involved have remained notably quiet. Reports indicate that Bank of America and PNC declined to provide substantive comments regarding the discussions. JPMorgan Chase and Wells Fargo reportedly offered no response when asked about the matter.
That silence has only intensified speculation.
As Durbin’s long Senate career nears its conclusion, the future of his signature financial regulation may depend less on congressional action and more on how aggressively America’s largest banks pursue opportunities created by changes in the payments industry.
Whether any deal ultimately materializes remains uncertain. What is clear, however, is that a law once marketed as a permanent safeguard against Wall Street excess now appears vulnerable to market forces and corporate innovation.
If major banks succeed in building or acquiring their own payment networks, the battle over debit-card fees could enter an entirely new chapter—one that may test whether Durbin’s landmark reform can survive in a rapidly evolving financial landscape.
