The Investment Industry Regulatory Organization of Canada proposed amendments to its dealer member rules to accommodate upcoming changes expected at ICE Clear Canada and the Canadian Derivatives Clearing Corporation to restrict linkages between a dealer member’s futures business and other business lines not subject to the Canadian futures market segregation and porting regime. Among other things, the amendments will set higher customer margin to accommodate the new CCP gross margin model; apply stricter criteria in order to apply offset margin requirements for customer cross-product hedges between securities and futures positions; and eliminate the potential of customer guarantees between securities and futures accounts. Comments will be accepted by IIROC through August 16.
