Abstract

Depuis la crise des subprimes, une grande refonte du cadre réglementaire des banques s'est engagée aboutissant, en décembre 2010, à la publication du dispositif connu sous le nom de Bâle 3. Parmi ses éléments constitutifs, il y a notamment le retour de la contrainte sur le levier des banques. Cet article expose les justifications théoriques de la nécessité de cette contrainte en complément du ratio de capital pondéré ainsi que les enseignements des expériences américaine et canadienne de coexistence de ces deux contraintes. Elle discute ensuite de la mise en œuvre de ce ratio de levier telle qu'elle est envisagée dans Bâle 3.
