Abstract
The growing focus of the IMF, World Bank, OECD, and European Commission on aligning finance with the Sustainable Development Goals (SDGs) raises the question of whether sustainability enhances banking sector profitability. This study aims to assess the impact of SDG performance on bank profitability, measured by return on assets (ROA), return on equity (ROE), and interest margin to gross income, controlling for GDP growth and inflation. The analysis uses an unbalanced panel of 143 countries over 2000–2024 (more than 2,100 country-year observations), applying fixed effects, random effects, and multilevel models with robust covariance estimators. The results show that the SDG Index Score has a weak and inconsistent effect on profitability. It is weakly positive for ROA (β = 0.125, p = 0.085) and marginally positive for interest margins (β = 0.151, p = 0.019), but becomes insignificant under robust specifications. For ROE, the SDG Index turns significantly negative in the random effects model (β = –0.119, p = 0.001), suggesting that higher SDG performance may be associated with lower equity returns. In contrast, the macroeconomic controls are robust across all models: GDP growth increases ROA (β = 0.107, p < 0.001) and ROE (β = 0.108, p < 0.001) but reduces interest margins (β = –0.061, p < 0.001), while inflation consistently raises profitability across all indicators. Regional patterns further indicate lower profitability in OECD and Western Europe and higher interest margins in East and South Asia, Latin America, and MENA.
