Penelitian ini bertujuan untuk menganalisis pengaruh Environmental, Social, dan Governance (ESG) terhadap nilai pasar bank di negara-negara anggota G7. Metode Two-Step Generalized Method of Moments (GMM) digunakan untuk mengestimasi model regresi dengan mempertimbangkan potensi masalah endogenitas dan autokorelasi. Hasil penelitian menunjukkan bahwa praktik ESG memberikan dampak positif signifikan pada nilai pasar bank di negara-negara G7. Namun, analisis khusus pada periode krisis Covid-19 mengungkapkan bahwa praktik ESG saat krisis justru dapat melemahkan nilai pasar bank. Temuan ini memberikan wawasan mendalam tentang kompleksitas hubungan antara praktik keberlanjutan dan performa nilai pasar bank, terutama dalam konteks krisis global. Implikasi praktis dan kebijakan dari hasil penelitian ini dapat membantu perbankan dan regulator untuk memahami lebih baik dampak praktik ESG pada stabilitas dan nilai pasar bank. / This study aims to analyze the influence of Environmental, Social, and Governance (ESG) on the market value of banks in G7 member countries. The Two-Step Generalized Method of Moments (GMM) method is employed to estimate the regression model, considering potential endogeneity and autocorrelation issues. The research findings reveal that ESG practices have a significant positive impact on the market value of banks in G7 countries. However, a specific analysis during crisis periods indicates that ESG practices during crises may actually weaken the market value of banks. These findings provide in-depth insights into the complexity of the relationship between sustainability practices and the financial performance of banks, especially in the context of a global economic crisis. The practical and policy implications of this research can assist banking institutions and regulators in better understanding the impact of ESG practices on the stability and market value of banks.
