iBoxx, the independent index provider, has launched a series of tradable collateralised debt obligation (CDO) tranches based on its European iBoxx Diversified index to improve liquidity for investors in the CDO market.

ABN Amro, Barclays Capital, Citigroup, Deutsche Bank, Dresdner Kleinwort Wasserstein and SG will quote prices on the TriBoxx new product in a credit default swap (CDS) format. The banks are members of the iBoxx CDS group, which was set up in February to act as a market maker on iBoxx's credit-linked notes.
