Bond index

Reflects the weighted average price of a bond portfolio — which consists of notional bonds or mortgage bonds — at a given point in time

Bond indices are calculated, updated and published by exchanges, banks and other financial experts.

A bond index can be calculated either as a price or a performance index. Owing to the wide range of bond maturities, bond indices are calculated on the basis of a portfolio of notional bonds so that the structure of the index remains constant over time.

Examples of bond indices in Germany are REX®, the iBoxx indices ( iBoxx EUR and iBoxx GBP), the eb.rexx index famlily and the PEX® .
