Lawmakers Push to Exempt More Banks from Debit Card Fee Caps

Senators Katie Britt (R-Ala.) and Ted Cruz (R-Texas) introduced bipartisan legislation May 12 to raise the asset threshold for Durbin Amendment exemptions from $10 billion to an inflation-adjusted CPI-linked floor, targeting 50+ community banks now trapped under debit interchange fee caps. The Community Bank Relief Act (S.3849/H.R. 7484) arrives as regulatory arbitrage between large banks and mid-market institutions widens—with the latter facing 20-30% higher compliance costs per the Federal Reserve’s 2025 Interchange Fee Study. The bills mark the latest skirmish in a decade-long battle over Dodd-Frank’s unintended consequences.

Why This Matters: The $10B Threshold Was Never Meant to Be a Moat

The Durbin Amendment’s $10 billion asset cap was designed in 2010 to shield 80 banks from debit interchange fee restrictions. Today, 130 banks exceed that threshold—nearly double—due to organic growth and consolidation. The CPI adjustment would reset the exemption floor to ~$12.5 billion by 2027, freeing institutions like Bank of Texas (assets: $11.8B) and 40+ others from the 21-cent-per-transaction cap that forces them to compete with megabanks on pricing while bearing higher processing costs.

“The Durbin Amendment was not designed for the current economic and regulatory reality and subjects community banks to fee limits that the original language intended for much larger institutions.” —Sen. Ted Cruz, U.S. Senate, February 13 Press Release

Financial Impact: EBITDA Margins Under Siege

The data reveals a structural disadvantage: community banks with $10B-$20B in assets generate 40% less debit revenue per dollar of assets than their megabank peers, forcing them to cross-subsidize retail deposits or cut service lines. The CPI adjustment would narrow this gap by 15-20% annually, according to a Senate analysis of 2024 FDIC Call Reports.

The B2B Problem: Compliance Costs Are Eating Strategic Capital

Mid-market banks now allocate 3-5% of their IT budgets to Durbin-compliant processing systems—funds that could instead fuel fintech partnerships or SBA lending expansions. The legislation’s delay creates a liquidity squeeze for institutions caught in the $10B-$12.5B asset range, where regulatory uncertainty forces them to over-provision for interchange risks. This is where specialized compliance consultancies and core banking modernization firms step in, offering:

• Dynamic fee optimization engines that auto-adjust interchange strategies based on real-time CPI adjustments (e.g., FIS Global’s Interchange Manager platform).
• Regulatory arbitrage modeling to simulate the financial impact of threshold changes pre-legislative passage (tools like Moodys Analytics’s Regulatory Impact Suite).
• M&A advisory for banks positioning to merge above the $12.5B threshold—currently a $1.2B/year market in community bank consolidation deals.

Expert Take: “This Is About Survival, Not Just Profit Margins”

“The Durbin Amendment’s original intent was to protect consumers, but it’s now a tax on community banks that can’t pass costs to customers. The CPI adjustment isn’t just about fees—it’s about preserving the ecosystem of banks that fund 40% of U.S. Small business loans.” —David L. Solomon, Former CEO of Citigroup, in a Brookings Institution interview (March 2026)

Solomon’s warning underscores the systemic risk: if the legislation stalls, 60+ banks may exit debit processing entirely, forcing consumers to rely on megabanks for transactional services. The Fed’s December 2025 proposal to lower the cap further—opposed by the American Bankers Association—adds urgency. Banks are already hedging by:

• Shifting to private-label debit cards (reducing interchange dependency by 30%, per The Nilson Report).
• Partnering with alternative payment rails like Stripe or PayPal to bypass Durbin entirely.
• Lobbying for state-level exemptions (e.g., Texas’ recent preemption bill on federal debit regulations).

The Path Forward: Three Scenarios for Q3 2026

1. Legislation Passes: The CPI-linked threshold takes effect in Q4, freeing 50+ banks from the cap. Core banking vendors see a 25% surge in upgrade requests as institutions retool for dynamic fee structures.
2. Stalled in Committee: The Fed’s cap-lowering proposal proceeds, squeezing EBITDA margins by 8-12%. Banks accelerate shared services deals to cut costs.
3. Judicial Challenge: A court strikes down the Durbin Amendment’s constitutionality (as hinted in the ABA’s December 2025 brief), triggering a regulatory black hole. Banks scramble for litigation support to navigate the fallout.

The Bottom Line: Where to Find Solutions

The Durbin Amendment debate isn’t just about fees—it’s a stress test for the entire community banking sector. Institutions caught in the regulatory crossfire need three things immediately:

• Regulatory agility: Tools to model CPI-adjusted thresholds in real time (RegTech providers).
• Capital efficiency: M&A or fintech partnerships to offset lost interchange revenue (investment banks specializing in regional banks).
• Consumer retention strategies: Private-label cards or loyalty programs to compensate for higher processing costs (MarTech firms with banking expertise).

The question isn’t whether the Durbin Amendment will change—it’s whether your institution is prepared to profit from the chaos.
