The greater use of clearing over-the-counter trades as a result of political and regulatory pressure will add $400m (€284m) to the combined annual revenues of four financial groups, according to new research. However, the figure is lower than many had expected as the groups will have to share profits to achieve a "buy-in" from dealer banks.

According to a report by Morgan Stanley, Atlanta-based derivatives market IntercontinentalExchange, London-based clearer LCH.Clearnet, Germany's Deutsche Börse and Chicago-based CME Group stand to make between $200m and $400m annually, as regulatory pressure pushes more over-the-counter derivative trades through clearing houses.
