Deutsche Börse has invested in a fledgling UK-based fixed-income trading platform, which is aiming to capitalise on tighter regulatory capital rules forcing major dealers to retrench from the bond market.

The Frankfurt-based exchange group has acquired a minority stake in Bondcube, a one-year-old fixed-income trading system, according to a statement today. The deal is for a "low sum in the single digit millions", the statement read.
