Abstract

Les banques centrales reconnaissent de plus en plus que le changement climatique est une source de risques financiers et qu'il pourrait affecter la transmission et la mise en œuvre de la politique monétaire. Dans ce contexte, cet article explore une approche permettant d'intégrer les risques climatiques dans la politique de collatéral d'une banque centrale. Cette approche se fonde sur des méthodologies dites d'« alignement » climatique, qui permettent d'estimer la cohérence des actifs éligibles et mobilisés dans le cadre du collatéral avec des objectifs climatiques. Plutôt que d'évaluer l'« alignement » de chaque actif, les banques centrales pourraient chercher à ce que les pools de collatéral mobilisés par chaque contrepartie soient compatibles avec des objectifs climatiques, cette approche allant moins à l'encontre du principe de neutralité de marché. Notre analyse montre qu'en agrégé, les actifs négociables éligibles et mobilisés au sein du cadre de collatéral de l'Eurosystème ne sont pas « alignés » avec les objectifs climatiques de l'Union européenne, ce qui suggère qu'ils sont exposés aux risques de transition. Nous présentons quelques implications pratiques de nos résultats et suggérons des pistes pour de futures études. Classification JEL : D81, E52, E58, G32, Q54.
