DCUC Warns Debit Interchange Ruling Threatens Credit Union Members and Military Families

Council pushes back on merchant claims and urges action to protect affordableaccounts and secure payments

WASHINGTON, DC — The Defense Credit Union Council (DCUC) today expressed disappointment with the Eighth Circuit’s decision in Corner Post v. Board of Governors of the Federal Reserve System, warning that the ruling threatens resources credit unions use to provide affordable accounts, prevent fraud, and deliver reliable payment services to servicemembers, veterans, military families, and communities nationwide.

“Merchant groups may celebrate this ruling, but credit union members have good reason to be concerned about who ultimately pays the price,” said Jason Stverak, DCUC Chief Advocacy Officer. “Reducing the revenue that supports secure payments does not eliminate the cost of providing them. It creates pressure to shift those costs onto the very consumers merchant advocates claim to be protecting.” The appeals court affirmed the lower court’s judgment vacating the Federal Reserve’s current 21-cent debit interchange cap and remanded the matter for the agency to develop a fee structure consistent with the court’s interpretation of the statute. The decision did not establish a replacement rate. The opinion states that the decision becomes effective when the court issues its mandate. DCUC emphasized that credit unions are member-owned, not-for-profit cooperatives whose earnings support member services and benefits. Further reductions in debit interchange revenue could strain affordable checking accounts, payment technology, and investments in fraud prevention. “The merchants’ focus on the biggest banks leaves credit unions and their members out of the story,” Stverak said. “Credit unions use these resources to serve people. Every debit transaction depends on systems that authorize payments, connect networks, and detect fraud. Those expenses remain real, regardless of which costs a court permits the Federal Reserve to recognize.” DCUC has repeatedly raised these concerns with policymakers. In its June 23, 2025, letter to the House Financial Services Committee, DCUC warned that additional interchange restrictions could shift costs to consumers and weaken community institutions. A December 8, 2025, joint letter to the Federal Reserve, signed by DCUC and other financial services associations, urged withdrawal of the agency’s proposed additional reductions and cautioned that lower merchant costs would not necessarily translate into lower retail prices. DCUC also joined an industry amicus brief in the separate Sixth Circuit case involving Linney’s Pizza, announced June 8, 2026, supporting the existing Regulation II framework against a related challenge. That advocacy warned that excluding actual transaction costs could force issuers to process payments at a loss and undermine investment in secure, accessible services. “For a military spouse managing household expenses during a deployment, or a young servicemember building financial stability, affordable checking and dependable access to money are necessities,” Stverak said. “Making those services harder to sustain carries consequences for military families. Their financial readiness deserves more consideration than a promise that merchant savings might reach the checkout counter.” The small-issuer exemption applies to institutions with less than $10 billion in assets, including affiliates. DCUC warned that while larger credit unions face direct exposure to the regulated fee standard, smaller, exempt institutions could still encounter competitive pressure on interchange revenue. Exemption from the cap does not guarantee insulation from broader market effects. DCUC urged the Federal Reserve to pursue available legal avenues to defend a sustainable debit payments framework and called on Congress to address the harm that further interchange restrictions could impose on credit union members. The Council also urged policymakers to scrutinize claims of consumer savings alongside the potential for higher account costs and reduced services. “A reduction in merchants’ expenses is no guarantee of lower prices for families,” Stverak said. “We will continue defending credit unions’ ability to provide affordable, secure financial services. Military families should not be handed the bill for merchant savings.”
