The current study investigates the association between corporate social responsibility (CSR) and financial performance (FP), and discusses the driving motives of banks to engage in CSR. Three motives, namely, strategic choices, altruism, and greenwashing, suggest that the relationship between CSR and FP is positive, non-negative, and non-existent, respectively. We obtained our sample, which covered 2003–2009, from the Ethical Investment Research Service (EIRIS) databank and Bankscope database. The data consists of 162 banks in 22 countries. We then classified the banks into four types based on their degree of engagement in CSR. This study proposes the use of an extended version of the Heckman two-step regression, in which the first step adopts a multinomial logit model, and the second step estimates the performance equation with the inverse Mills ratio generated by the first step. The empirical results show that CSR positively associates with FP in terms of return on assets, return on equity, net interest income, and non-interest income. In contrast, CSR negatively associates with non-performing loans. Hence, strategic choice is the primary motive of banks to engage in CSR.

We conduct an international study on the effect of climate policy uncertainty on the systemic risk of banks from G20 countries. We find that climate policy uncertainty is associated with lower bank systemic risk. This relation is more pronounced in countries with high innovation capacity, climate readiness, more systemically important banks, and a more competitive banking system. Climate-related information disclosure and sustainable investments are critical economic channels through which the effect of climate policy uncertainty works. Our findings alleviate the concern that climate transition risk may contribute to financial instability and provide practical implications for regulators to design climate transition policies.
