Report: European Retailers Seek Antitrust Case Against Mastercard And Visa

A group of trade associations representing European retailers reportedly asked the European Commission to take action against Mastercard and Visa under European Union antitrust rules, alleging that the companies charge high fees and don’t provide transparency on those fees. In a letter dated Tuesday (May 13) and addressed to the commission’s antitrust chief, financial services commissioner and economy chief, the associations also called for price controls on interchange fees, transparency and non-discriminatory obligations for International Card Schemes (ICSs), and a tool for regulators to scrutinize ICSs’ actions, Reuters reported Wednesday (May 14), citing a copy of the letter. “International Card Schemes (ICS) have been able to increase their fees without competitive challenge or regulatory scrutiny,” the letter said, per the report. “They have also rendered their system of fees and rules so complex and opaque that players are unable to understand, let alone challenge, what they are paying for and why.”
