Abstract

La finance moderne se déroule dans un monde magnifiquement bien dessiné. Dansun formidable élan impulsé à partir du début des années 50 et jamais démenti depuis, ce domaine se dote d'outils puissants et se sophistique pour offrir les meilleurs services et produire les meilleurs résultats. Depuis, la connaissance du risque est une condition d'exercice de la finance : elle n'a plus de sens sans lui. N'y-a-t ‘il pas ici un paradoxe ? alors que nous savons maintenant que le risque est consubstantiel à la finance, que notre savoir et nos outils progressent, les crises financières sont plus rapprochées et plus profondes… Après un bref historique de la prise en compte du risque dans la finance moderne, ce chapitre apporte des explications concernant les causes de négligences dans la prise en compte du risque en dépit de son caractère déterminant. Nous examinons ensuite les excès d'une telle situation en illustrant de faits empruntés à l'actualité récente. Enfin, nous proposons des pistes de réflexion pour penser une pratique plus responsable de la finance qui redonne sens et profondeur à cette notion de risque qu'elle "adresserait" en connaissance des conséquences.
