The SGX annual report discloses a reciprocal cross-exchange collateral structure: CME lodged a S$517.8m letter of credit, while SGX-DC carried S$491.9m of related guarantees. The mechanism is distinct from ordinary member margin and cannot be read as free corporate liquidity.
The integration covers standard, E-mini and Micro futures. Advertised commissions exclude exchange and NFA fees, so the headline rate is only part of the cost of opening and closing a position.
CME Clearing and Globex notices identify new RBOB and Gulf Coast gasoline contracts, testing dates and product codes; the futures were not trading as of 30 October.
The reported CME settlement concerns large displayed orders cancelled after opposite-side fills. Firm and trader share one $759,910.22 disgorgement obligation.
