    [fre] Cet article décrit l’environnement des années 2000 au sein duquel les institutions financières avaient grand besoin de diversification. Il pose également la question de l’étendue des recettes de la diversification réalisées dans les grands groupes financiers. Il montre ainsi qu’aussi bien les groupes à dominante bancaire que ceux à dominante assurancielle continuent à être fortement concentrés sur leur activité première. De plus, l’importance relative de cette activité dans leurs revenus a également augmenté durant cette période. Dans le même temps, il n’existe que peu d’exemples dans lesquels des groupes financiers connaissant des difficultés dans leur activité de base, ont obtenu un soutien de la part de leurs activités annexes. Ainsi, cet article ne fournit qu’un soutien limité à l’hypothèse selon laquelle les groupes financiers ont bénéficié de la diversification de leurs activités durant la récente crise financière. Classification JEL : G21, G22, G34 [eng] The article focuses on the post-2000 environment, during which financial institutions were most in need of diversification benefits, and it asks to what extent revenue diversification benefits were realised in large financial groups. It finds that both insurance-dominated and bank-dominated groups continued to be highly concentrated on their «core business» and, moreover, that the relative importance of their core business activities for revenues during this period even increased. At the same time, there have been only very few instances where financial groups that were experiencing pressures on their «core activity» revenues obtained some relief from increased contribution from «non-core business» activities. Thus, the evidence presented in the article provides only limited support in favour of the hypothesis that financial groups have benefited from revenue diversification during the recent period of financial distress. JEL classification : G21, G22, G34
