Antitrust regulators in the European Union have expanded their investigation into a small network of banks that allegedly unfairly controlled the derivative market. Barclays, JPMorgan, Chase and Deutsche Bank were already included in the investigation and it now has been broadened to include the International Swaps and Derivatives Association (ISDA), a trade organization for market participants. According to a statement from the European Commission, they “found preliminary indications that I.S.D.A. may have been involved in a coordinated effort of investment banks to delay or prevent exchanges from entering the credit derivatives business. Such behavior, if established, would stifle competition in the internal market in breach of E.U. antitrust rules.”

According to AP, the fine is a first, since the company is the first to fail to uphold the terms of an agreement with European Union (EU) authorities.
