ITraxx
iTraxx (Thomson Reuters Eikon code 'ITRAXX'; Bloomberg code 'ITRX') is the brand name for the family of credit default swap index products covering regions of Europe, Australia, Japan and non-Japan Asia. Credit derivative indexes form a large sector of the overall credit derivative market. The indices are constructed on a set of rules with the overriding criterion being that of liquidity of the underlying credit default swaps (CDS).
The group of indices was formed by the merger in 2004 of the Trac-X indices created by J.P. Morgan & Co. and Morgan Stanley and the iBoxx CDS indices created by IBoxx.
