Résumé Cet article analyse la transmission des politiques climatiques à l'allocation du crédit bancaire dans la zone UEMOA entre 2015 et 2024. La méthodologie repose sur un modèle de panel à effets fixes banque-pays-trimestre appliqué à un échantillon de 40 banques (n = 1 560 observations), en adaptant l'approche de Covi et al. (2025). Les résultats révèlent une transmission quasi inexistante des politiques climatiques : le coefficient associé à l'indice CCPI est faible et non significatif (β = 0,04 ; p > 0,10) pour les expositions vertes (TAC), de même que pour les secteurs carbonés (β = −0,02 ; p > 0,10). En revanche, l'inflation constitue le principal déterminant de l'allocation : une hausse de 1 point du taux d'inflation entraîne un rééquilibrage d'environ +3,5 % vers les secteurs résilients (β = 0,0014 ; p 0.10) for green exposures (TAC), as well as for carbon-intensive sectors (β = −0.02; p > 0.10). In contrast, inflation emerges as the main determinant: a one-point increase in the inflation rate leads to an estimated +3.5% reallocation toward more resilient sectors (β = 0.0014; p < 0.05), indicating macroeconomic dominance over climate signals. The findings highlight a substantial gap in the integration of climate risk within WAEMU banking practices. The average share of "green" loans remains below 2% of total portfolios, while exposure to vulnerable sectors still exceeds 28%. The study calls for strengthening the BCEAO's prudential framework: mandatory climate stress tests, standardized disclosure requirements, and targeted regulatory incentives.
