Abstract

The estimated medium-term impact of Basel III implementation on GDP growth is in the range of -0.05 to -0.15 percentage point per annum. Economic output is mainly affected by an increase in bank lending spreads as banks pass a rise in bank funding costs, due to higher capital requirements, to their customers. To meet the capital requirements effective in 2015 (4.5% for the common equity ratio, 6% for the Tier 1 capital ratio), banks are estimated to increase their lending spreads on average by about 15 basis points. The capital requirements effective as of 2019 (7% for the common equity ratio, 8.5% for the Tier 1 capital ratio) could increase bank lending spreads by about 50 basis points. The estimated effects on GDP growth assume no active response from monetary policy. To the extent that monetary policy will no longer be constrained by the zero lower bound, the Basel III impact on economic output could be offset by a reduction (or delayed increase) in monetary policy rates by about 30 to 80 basis points. Impact macro-économique de Bâle III L'impact estimé à moyen terme de la mise en conformité avec les règles de Bâle III sur la croissance du PIB est de l'ordre de -0,05 à -0,15 point de pourcentage par an. L’effet sur l’activité économique provient principalement de ce que les banques augmentent leurs marges de crédit afin de compenser la hausse de leurs coûts de financement provoquée par le durcissement des exigences de capital. Pour répondre aux exigences de fonds propres en 2015 (4,5% pour le ratio d'actions ordinaires, 6% pour le ratio de fonds propres de base), les banques devraient augmenter leurs marges de crédit d'environ 15 points de base en moyenne. Les exigences de capital en vigueur à compter de 2019 (7% pour le ratio d'actions ordinaires, 8,5% pour le ratio de fonds propres de base) pourraient augmenter les marges de crédit d’environ 50 points de base. Les effets estimés sur la croissance du PIB n’incorporent aucune réponse de la politique monétaire. Pour autant que la politique monétaire ne se heurte plus au plancher zéro des taux nominaux, l'impact de Bâle III sur la production économique pourrait être compensé par une réduction (ou un retard avant l’augmentation) des taux de la politique monétaire d'environ 30 à 80 points de base.
