Barclays Capital has agreed to make markets in the two biggest competing credit derivative index-linked platforms, in the latest sign that the market has not produced a single leader.

The UK-based investment bank is joining ABN Amro, Citigroup, Deutsche Bank, Dresdner Kleinwort Wasserstein and Société Générale on iBoxx credit-linked platform, which consists of funded and unfunded notes linked to three credit derivative indices, the iBoxx diversified, the iBoxx 100 and the iBoxx corporate.
