REX (German bond index)

Weighted average price of 30 domestic German bonds

REX® expresses the value of a representative segment of the German bond market. It is calculated by Deutsche Börse on the basis of 30 domestic bonds once daily. It is based on cash prices determined on FWB® Frankfurter Wertpapierbörse (the Frankfurt Stock Exchange). The index takes into account bonds with a time to maturity of one to ten years, expressed as an integer, and three interest rates (6, 7.5 and 9 percent). Each of the 30 bonds is weighted according to its market share, which is determined by the number of issues in each of the 30 maturity-/interest-rate categories over the past 25 years. Deutsche Börse reviews the weighting annually.
