Crise de la dette souveraine dans l’Union européenne : transparence des banques et spreads de CDS

Abstract

Nous étudions l’impact de la transparence des banques sur l’évolution des spreads de leurs credit default swaps (CDS) pendant la crise de la dette souveraine au sein de l’Union européenne. La transparence aide les investisseurs à fonder leurs anticipations et peut réduire la prime de risque informationnelle ainsi que les spreads de CDS. Nous calculons la variation anormale cumulée du spread (VACS) lors de seize annonces de dégradation de notation souveraine, de 2011 à mi-2013. Nous construisons deux indices de transparence : l’un mesure la transparence globale de la banque, l’autre mesure sa transparence vis-à-vis de l’exposition au risque souverain. Nous montrons que l’exposition au risque souverain accroît la VACS, alors que la transparence de la banque vis-à-vis de ce risque réduit la VACS ; l’information tend donc à réduire la prime de risque. Cependant, la transparence globale augmente la VACS ; les investisseurs semblent désapprouver une communication trop large et trop abondante.
