OCC announced on 5 October that it will clear and settle trades for IEX Options, the new venue launched by Investors’ Exchange on 2 October. It is OCC’s first clearing relationship with IEX and lifts OCC’s participant-venue roster to 20 options exchanges, two futures exchanges and one stock-loan exchange.
FMI WORLD analysis: A new trading venue can compete on execution design while post-trade risk remains concentrated at the established U.S. listed-options CCP. That common clearing layer gives members multilateral netting and a single risk-management framework across venues, but it also extends OCC’s systemic operating perimeter as the options landscape becomes more fragmented.
IEX Options participants, OCC clearing members, options market makers, brokers, technology vendors, other U.S. options exchanges and regulators overseeing systemically important market infrastructure.
IEX Options volume and market share; clearing-member onboarding and operational performance; whether the venue attracts distinct order flow; any OCC margin or risk-management adjustments; and how another execution venue changes fragmentation without altering the common CCP.
