UBS Warburg is the latest investment bank to provide its backing to Mark-it Partners, the London-based pricing service for credit derivatives and cash credit instruments that was launched in January.

UBS Warburg on Tuesday joined 11 other banks as a contributing partner with Mark-it. The Swiss bank will feed its credit pricing data to Mark-it on a daily basis in return for access to Mark-it's services and the option to take an equity stake in the fledgling company.
