Abstract

[eng] Financial markets' failures and risk of system. In the recent years, very various financial and derivative markets have been hit by a succession of disorders. In this paper, we review different periods during which volatility and liquidity problems have increased significantly, with potential repercussions likely to result in a risk of system. . Converging lessons can be drawn from these various episodes as regards the origins of risk of market. Three main factors stand out, that may have aftereffects : a destabilizing dynamics of prices under conditions of stress, the difficulties to estimate credit risk and the vulnerability to an illiquidity crisis. . There exists parades to market risk. The more important are the use of an internal model of risk evaluations for elaboration of prudential rules, the authorities' recommandations regarding the appropriate disclosure of the market risk and credit risk characteristics, the elaboration of catastrophe scenari and more constraining capital requirements to market risks. [fre] Ces dernières années une série de bouleversements ont touché des marchés financiers et dérivés très divers. On passe en revue certaines périodes pendant lesquelles la volatilité et les problèmes de liquidité se sont accrus de manière importante, avec des retombées potentielles propres à entraîner un risque de système. Des enseignements convergents peuvent être tirés de ces divers épisodes en ce qui concerne les sources de risque systémique. Trois facteurs principaux se détachent, qui peuvent avoir des effets d'entraînement : une dynamique de prix déstabilisante dans des conditions de stress, les difficultés d'évaluation du risque de crédit et la vulnérabilité à une crise de liquidité. . Il y a des parades au risque de marché. Les principales sont l'emploi de modèles internes d'évalution des risques pour la formulation de règlements prudentiels, les recommandations des autorités concernant la divulgation appropriée des caractéristiques des risques de marché et de crédit, l'élaboration de scénarios catastrophe, et des exigences en capital pour risques de marché plus contraignantes.
