The World Federation of Exchanges said futures trading increased 35% last year to 11.2 billion contracts. Options trading rose 16% to 11.1 billion contracts. Trading of commodity derivatives was up 34%, with Chinese exchanges accounting for more than 50%. Global exchange-traded derivatives reached 22.4 billion contracts. "Reforms in regulation of over-the-counter derivatives markets are causing participants to shift some of their risk-transfer activities to exchange-traded derivatives," said Ronald Arculli, chairman of WFE and Hong Kong Exchanges and Clearing.
