(The Wall Street Journal) -- Credit Suisse has decided to stop making markets in European government bonds on four trading platforms operated by MTS, protesting MTS's decision to open trading to hedge funds.

The Credit Suisse decision could pave the way for other banks to shift their bond market-making businesses away from MTS as platform requirements ease. Rivals include Bloomberg, Eurex Bonds, Icap's BrokerTec platform and Espeed, which is an affiliate of Cantor Fitzgerald.
