The ninth respondent, Nomura International PLC, is alleged to have participated in a conspiracy involving the trading of the USD/ZAR currency pair, primarily through traders Mr. Guido Arlan and Mr. Darren Dempsey. The Commission claims that Nomura joined the alleged "single and continuous infringement" (SOC) conspiracy by at least October 18, 2012, when Dempsey was in a chatroom where the bid-office spread for USD/ZAR was discussed. Prior instances from as early as May 2010 and discussions in March 2012 also involved Nomura in relevant chatrooms.
However, the Tribunal found significant challenges in establishing Nomura’s participation in this alleged conspiracy. Notably, two key chats occurred before the Commission's alleged start date for Nomura's involvement, rendering the evidence insufficient. The Tribunal recognized that the evidence supporting Nomura’s involvement was sparse, particularly that only one vague reference to Dempsey was cited, making it difficult to prove personal jurisdiction or actual knowledge of a common anticompetitive objective.
The Tribunal’s conclusions highlight shortcomings in the Commission's case against Nomura, emphasizing that the evidence was not adequate to meet the necessary criteria for proving participation in the SOC. As the referral affidavit provided scant information linking Nomura to the alleged conduct, the overall case against the ninth respondent was deemed weak.
