Abstract

[fre] Le risque systémique peut provenir de la contagion déclenchée par un choc exogène ou être engendré dans le cycle financier de manière endogène par l'interaction du crédit et du mouvement des prix des actifs. La gestion du risque fondée sur l'utilisation de la VaR et dans les transferts des risques de marché et de crédit par les produits dérivés a accru l'importance du second type de risque systémique. Une interdépendance stratégique s'est ainsi nouée dans le système financier international entre les banques et les non banques. Elle entraîne le risque systémique lorsque les conditions macroéconomiques du cycle se retournent. Les Banques centrales devraient construire des indicateurs macroéconomiques avancés de l'accumulation des fragilités financières dans la phase montante du cycle et élaborer des tests de stress macroéconomiques pour tenter de déceler la formation d'interdépendances stratégiques sur des marchés critiques. L'aptitude à maintenir le système financier liquide s'impose après le retournement du cycle des prix d'actifs. . Classification JEL : E44, F3, G15 [eng] Systemic and financial liberalization. Systemic risk may stem from a contagion process triggered by an exogenous shock or be originated endogenously in the financial cycle by the interplay of credit and asset prices. Financial liberalization has played down the first type and magnified the second type of systemic risk. This shift can be explained by the widespread use of the VaR framework in internal risk control systems and by risk transfer mechanisms via derivative markets. A Strategic interdependence has intertwined banks and non banks throughout the financial system worldwide. lt leads to systemic risk while the macroeconomic conditions of the cycle have turned around. Central banks should conceive leading macroeconomic indicators . to detect the buildup of financial fragilities in the upswing of the cycle and run macro stress tests in collaboration with international banks to pinpoint strategic interdependencies on critical markers. Keeping the financial system liquid is of primary importance after the turn down of asset prices. . JEL classification : E44, F3, G15
