Pulse Analysis

The Durbin Amendment, enacted in 2010, forced the Federal Reserve to cap debit‑card interchange fees at roughly 0.05% of a transaction plus a flat cent amount. Proponents argued lower merchant costs would translate into cheaper goods, but economists note that these fees subsidize consumer benefits—cash‑back rewards, free checking, and lower minimum balances—through a two‑sided market model. When the caps were imposed, banks responded by shifting revenue to account‑maintenance fees, a shift that has been linked to higher costs for underbanked households.

Legal scholars now watch Linney’s Pizza because it tests the Fed’s discretion in the wake of the Supreme Court’s Loper Bright ruling, which rejected the Chevron doctrine that once gave agencies broad leeway in interpreting statutes. The case hinges on whether the Durbin Amendment’s language—requiring fees to be “reasonable and proportional” to an issuer’s costs—allows the Fed to consider broader transaction‑specific expenses beyond pure incremental authorization costs. The district court previously upheld the Fed’s inclusion of fixed costs, fraud losses, and network‑processing fees, arguing that a narrower reading would render the statutory qualifier meaningless.

The broader stakes extend beyond one pizza shop. If the appellate court sides with Linney’s Pizza, the Fed may be forced to further lower interchange fees, likely prompting banks to increase checking‑account fees or tighten free‑service thresholds. Such a shift would erode the consumer‑benefit cushion that many low‑income customers rely on, potentially expanding the unbanked population. Conversely, a decision affirming the Fed’s broader discretion would preserve the current balance, reinforcing agency authority to weigh consumer welfare in fee calculations. Either outcome will set a precedent for how administrative agencies navigate statutory interpretation after Chevron’s demise, influencing future regulation of payment‑card networks and other two‑sided platforms.
