Major US Banks Explore Fiserv Network Deal to Bypass Debit Card Fee Caps

A consortium of the largest U.S. banks, including JPMorgan Chase, Bank of America, Wells Fargo, and PNC Financial Services, has held preliminary discussions in recent months to acquire a debit payments network from fintech company Fiserv. The strategic aim of the potential acquisition, according to a Wall Street Journal report citing people familiar with the matter, is to create a pathway around federal caps on debit card interchange fees that have limited bank revenue for over a decade.

The talks, which remain tentative, center on Fiserv’s STAR and Accel networks. These networks act as crucial intermediaries, processing debit transactions between merchants and the banks that issue the cards. By owning such a network, the banking consortium could potentially process transactions on its own infrastructure, a move that could exempt them from the fee limits mandated by the Durbin Amendment, a provision of the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act.

The Durbin Amendment was a landmark piece of financial regulation that capped the “swipe fees” banks with over $10 billion in assets could charge merchants for processing debit card transactions. The Federal Reserve set the initial cap in 2011 at 21 cents plus 0.05% of the transaction value. These fees, which generated over $31.5 billion for lenders in 2021 according to Fed data, have been a point of contention ever since. Banks have consistently argued that the limits curtailed revenue that supported services like free checking accounts, fraud protection, and debit card rewards programs. Conversely, merchant associations have championed the caps, contending they reduce operating costs and help keep consumer prices in check.

The current exploration by major banks represents a significant escalation in this long-running battle. The potential acquisition strategy appears to have gained momentum following Capital One’s $35 billion deal to acquire Discover Financial earlier this year. That transaction gave Capital One ownership of a card network, allowing it to bypass middlemen and deal more directly with merchants, a structure that other large banks are now evidently keen to replicate.

This renewed interest also comes as regulatory pressure on interchange fees is increasing. In October 2023, the Federal Reserve proposed a new rule that would slash the debit card fee cap by nearly 30%, from the current 21 cents to 14.4 cents per transaction. The Fed cited data showing that the actual costs for banks to process these transactions had fallen by almost half since the cap was first established. This proposal, currently open for public comment, has intensified the banking industry’s search for alternative revenue models and workarounds.

If the banks were to acquire and operate their own network, they could set their own fee structures for transactions processed through it, effectively sidestepping the Durbin Amendment’s restrictions. For small and mid-sized businesses, which rely heavily on card payments, such a development could lead to a significant increase in payment processing costs, directly impacting their bottom lines. Merchant groups have long argued that any savings from fee caps are passed on to consumers, a claim banks dispute.

However, the path to such a deal is fraught with obstacles. The sources familiar with the discussions noted that several of the participating banks are skeptical that a transaction will ultimately materialize. A primary concern is the high probability of intense political and regulatory scrutiny. An acquisition of this scale, designed explicitly to circumvent a major piece of post-financial crisis legislation, would almost certainly trigger antitrust reviews from the Department of Justice and other regulatory bodies. Lawmakers and consumer protection groups would likely frame the move as an anti-competitive maneuver by Wall Street to increase costs for merchants and, by extension, consumers.

The discussions highlight a fundamental tension in the U.S. payments ecosystem. While banks seek to maximize revenue from their card-issuing operations, merchants are pushing for lower processing costs in an increasingly digital economy. The outcome of these preliminary talks could set a new precedent for how payment networks are owned and operated in the United States.

In our experience, the strategic maneuvering between large financial institutions and payment processors often has direct, tangible consequences for small and mid-sized businesses. While this specific deal to acquire a network is still speculative, the intent behind it is clear: banks are aggressively seeking ways to increase fee-based revenue. This signals that merchants should prepare for a future with potentially higher payment processing costs, regardless of whether this particular acquisition proceeds. Business owners cannot afford to be passive observers. They must proactively analyze their current cost structures and model how even a fractional increase in swipe fees could impact profitability. This is precisely the kind of forward-looking financial strategy that outsourced CFO services can provide, helping companies build resilience against market shifts driven by Wall Street.

Moving forward, all eyes will be on whether these tentative discussions solidify into a formal acquisition offer for Fiserv's networks. Observers will also be watching for any preemptive statements or actions from federal regulators and Congress, who are likely to take a keen interest in a deal that could fundamentally rewire the economics of the nation's debit card system. The response from powerful retail and merchant lobbying groups will also be a critical factor in determining the viability of such a transaction.
