In the increasingly urgent scenario of sustainable development, financial institutions are emerging as key players in the advancement of the Sustainable Development Goals (SDGs) outlined in the 2030 Agenda. As such, considering the role that banks play in the economic landscape, it is crucial to clarify how they support the above-mentioned objectives. While existing literature has primarily focused on the disclosure features of financial institutions related to SDGs, there is a lack of studies examining the determinants of SDG performance. This gap underscores the need for in-depth investigations into the impact of bank characteristics on the effectiveness of SDGs achievement. Hence, this study aims to bridge this gap by delving into the extent to which the financial characteristics of banks impact SDG performance. To this end, a panel analysis was conducted on a group of global banking entities. The sample used consists of 646 publicly listed banks in 61 countries, considering the period from 2018 to 2023. Empirical results show that larger and less profitable banks reach better performance in terms of contribution to SDGs. The level of leverage does not appear to be a significant influential factor in fostering the support of the SDGs. By identifying the specific financial characteristics that contribute to SDG performance, this study provides theoretical implications related to the role of financial institutions in promoting sustainable development.
