On Friday, March 21, the United States Court of Appeals for the District of Columbia handed retailers a considerable setback in their ongoing war against banks over price controls on interchange fees-the fees charged to retailers when they accept debit cards as payment. The court's decision is the latest salvo in the wake of the Durbin Amendment, which was hurriedly and quietly added to the Dodd-Frank financial services reform legislation of 2010. The amendment mandated that the Federal Reserve Board establish price caps for debit card interchange fees. Retailers claimed the caps were necessary to protect consumers, but the reality of the Durbin Amendment has been a direct transfer of resources from banks to retailers, with consumers facing higher costs as collateral damage.
