When the Dodd-Frank Wall Street Reform and Consumer Protection Act was passed in 2010, the “Durbin Amendment” required the Federal Reserve Board to establish standards for assessing whether debit interchange fees are “reasonable and proportional” to the cost incurred by the issuer with respect to the debit card transaction.
In ensuing years, there has been substantial scholarship – including research from Board economists involved with the proposed rule – demonstrating the Durbin Amendment, or Regulation II, resulted in banks “decreasing the availability of free accounts, raising monthly fees, and increasing minimum balance requirements.” Even small issuers exempt from Regulation II were shown to have raised prices, as a competitive response.
