Why Are Huge Debit Card Issuers Still Paying Visa to Route Payments?

Why It Matters

A network acquisition would shield the banks from regulatory fee caps, unlocking billions in incremental revenue and reshaping the competitive landscape of U.S. payments.

Key Takeaways

• BofA, Chase, Wells Fargo process $1.425 trillion debit volume annually
• Durbin cap cuts could slash interchange revenue by $2‑5 billion
• Capital One’s Discover acquisition bypasses price controls, boosting margins
• Owning a network could raise interchange to 140 bps, adding $20 billion

Pulse Analysis

The Durbin Amendment, enacted in 2011, caps interchange fees for large issuers at roughly 50 basis points, a level that has become increasingly untenable as processing costs have fallen. For Bank of America, Chase and Wells Fargo, the cap translates into $2 billion of lost revenue this year, and a potential $4.7 billion hit if courts deem the current methodology illegal. This regulatory pressure coincides with a broader industry shift: Capital One’s acquisition of Discover freed it from the cap, allowing it to charge market‑driven interchange rates and capture higher margins. The move has already pressured rivals to reconsider their reliance on Visa‑branded rails.

Owning a proprietary debit network would give the three banks direct control over routing, licensing and processing fees that currently flow to Visa. Networks such as Star, Accel or NYCE sit idle as secondary utilities, yet they possess the infrastructure to support high‑volume retail transactions. By converting their Visa‑branded portfolios to a self‑owned rail, the banks could lift interchange from the current 49 basis points to the market‑typical 140 basis points, generating an estimated $20 billion in additional annual revenue. Moreover, a bank‑run network would enable bespoke merchant negotiations and targeted promotions, further enhancing consumer value.

Beyond fee recovery, a network acquisition would blunt legal exposure. The Department of Justice’s antitrust suit against Visa hinges on the banks’ dependence on third‑party networks; owning the rail would remove that vulnerability. Additionally, as surcharging on credit cards gains regulatory acceptance, debit usage is poised to rise, amplifying the strategic importance of a robust, high‑margin debit offering. In sum, purchasing a debit network presents a clear path for BofA, Chase and Wells Fargo to reclaim profitability, drive innovation, and reshape the U.S. payments ecosystem.
