RDAX® is a corporate bonds index which tracks the performance of bonds issued by DAX® 30 companies. Deutsche Börse is the first index provider to bundle the bonds issued by companies of a blue-chip index in a separate fixed-income index.

The index RDAX® is based on a transparent set of rules that comply with the internationally accepted EFFAS principles. Only euro-denominated corporate bonds issued by the DAX® companies with an “investment grade” rating (BBB- or better) will be included in the index. Additionally, bonds must have an outstanding issuing volume of at least €500 million and a minimum time to maturity of one year. With the focus on corporate bonds of DAX® companies plus the strict selection criteria, Deutsche Börse ensures both the high quality of the index and the liquidity of the index components.

The RDAX index is calculated minute-by-minute on the basis of iBoxx® € consolidated prices, which are derived from real-time prices of ten investment banks with leading positions in bond trading.
