Le contenu en information de la pente des taux : application au cas des titres publics français.

This paper evaluates the information content of the term structure about future changes in interest rates and changes in inflation rate, in France. A data set has been constructed, which contains zero-coupon yield curves on government bonds over the period 1980-95. The information content is generally very weak over the whole period. On the contrary, over the period 1985-95, the term structure contains information for certain maturities. On the one hand, spreads vis-à-vis 2-year rates are informative for future changes in short-term rates, whereas spreads vis-à-vis 3-year rates are informative for both future changes in short-term rates and future changes in long-term rates; on the second hand, the spreads from (2- versus 1-year rates) to (5- versus 1-year rates) and (4- versus 2-year rates) are the most informative for future changes in inflation rate.
