Eighth Circuit Overturns $0.21 Card Fee Cap, Reinstates Transaction‑Specific Analysis
The U.S. Eighth Circuit ruled that the Federal Reserve’s $0.21 debit‑card fee cap is invalid, requiring a transaction‑specific cost analysis under the Durbin Amendment.
The Eighth Circuit held that the Durbin Amendment obliges the Federal Reserve to evaluate interchange fees on a transaction‑by‑transaction basis, invalidating the blanket $0.21 cap that had lowered rates for many merchants. Banks must now recalculate fees per transaction, which could raise costs for merchants and prompt renegotiation of fee schedules. Firms advising banks and merchants should review existing fee structures, assess the impact on their clients, and monitor whether the Fed will respond with new guidance or enforcement changes that could further influence the debit‑card ecosystem. The ruling also signals that the Federal Reserve cannot unilaterally set interchange rates; instead, future policy must involve explicit cost calculations. As a result, chief financial officers of banks and merchant service providers should immediately conduct a cost‑analysis audit of current interchange fee arrangements. The decision may prompt additional litigation challenging the amendment’s enforcement, and could attract the attention of the Consumer Financial Protection Bureau if merchants and consumer groups argue a change in pricing harms small businesses. Big law teams should prepare to advise clients on mitigating exposure, possibly by negotiating interim fee caps or preparing for federally mandated reporting requirements.
