ESG Performance and Banks’ Funding Costs Alin Marius AndrieΘ Alexandru Ioan Cuza University of IaΘi and Institute for Economic Forecasting, Romanian Academy E-mail: alin.andries@uaic.ro Nicu Sprincean Alexandru Ioan Cuza University of IaΘi and National Institute for Economic Research, Romanian Academy E-mail: sprincean.nicu@uaic.ro Abstract In this study, we explore whether and to what extent Environmental, Social, and Governance (ESG) factors impact banks’ funding costs. Using a sample composed of 493 banks located in 39 advanced and emerging economies over the 2003-2020 period, we find that banks benefit from incorporating ESG practices into financial decisions, enjoying lower costs of raising interestbearing liabilities (total cost of funds), as well as reduced costs of attracting deposits. All ESG dimensions are responsible for this outcome in the case of total cost of funds, whereas for the cost of deposits the Environmental pillar appears to have an insignificant impact, suggesting that depositors do not value banks' environmental commitments, but rather their social performance and corporate governance quality. Furthermore, the empirical evidence indicates that only large banks and those located in developed countries reap the benefits of increased ESG performance in terms of reduced financing costs.

Introduction Although the Environmental, Social and Governance (hereafter ESG) factors emerged since 1980’s as a way for investors to evaluate a company’s performance (Berg et al., 2022), their impact on firms’ cost of financing has been investigated empirically only recently and is still subject to debate. Moreover, the majority of the studies concern non-financial corporations, whereas financial institutions have received much less attention. Recently, the European Central Bank set the deadline as the end of 2023 for euro area banks to incorporate climate and environmental risks into their governance, strategy, and risk management plans (ECB, 2022). In a similar fashion, the Federal Reserve Board proposed a plan for banks with assets exceeding 100 billion USD to address climate-related financial risks, and the six largest U.S. banks will have to assess the potential impact of these risks on their operations in a pilot climate scenario by July 31, 2023 (Reuters, 2023). According to the shareholder view, the mission of a company is to undertake positive net present value projects to maximize shareholders’ wealth (Friedman, 1970). An alternative to this perspective is the stakeholder theory put forward by Freeman (1984) which states that a firm can succeed by doing good (Bénabou and Tirole, 2010). In this regard, a business should consider the impact of its operations on all parties involved, i.e., the creditors, employees, governmental bodies, customers, suppliers etc., and aim to create value for them as well and uphold their interests. Previous evidence support the stakeholder orientation of a company and show that ESG/Corporate Social Responsibility (CSR)1 performance is linked with better profitability (Gangi et al., 2019), increased satisfaction of both customers and employees (Servaes and Tamayo, 2013), and less individual risk-taking (Neitzert and Petras, 2021) and systemic risk in the banking sector (Aevoae et al., 2022).2 Murè et al. (2021) point-out that ESG represents one of the variables that can impact the reputation of financial institutions, which in turn influences the cost of debt (Maaloul et al., 2021). In the same vein, both financial (Francis et al., 2005; Ng and Rezaee, 2015) and non-financial (Goss and Roberts, 2011; El Ghoul et al., 2011; Dhaliwal et al., 2014; Ng and Rezaee, 2015; Eliwa et al., 2021; Wang et al., 2021; Azmi et al., 2021; Agnese and Giacomini, 2023; Degryse et al., 2023) disclosures are found to be value-relevant and affect the cost of capital. 1 Although ESG dimensions are employed as proxy for Corporate Social Responsibility (CSR) and used interchangeable in the literature, Gillan et al. (2021) note that ESG is a broader term that incorporates governance explicitly, while CSR covers it indirectly. 2 For recent reviews, see Rau and Yu (2023) and Tsang et al. (2023). Electronic copy available at: https://ssrn.com/abstract=4359454 While El Ghoul et al. (2011), Dhaliwal et al. (2014), Ng and Rezaee (2015), Eliwa et al. (2021), Azmi et al. (2021), Agnese and Giacomini (2023) and Degryse et al. (2023)3 document a negative association between sustainability 4 and companies’ cost of capital, Goss and Roberts (2011) show that banks do not reward businesses that perform better in terms of CSR-related activities as compared to their peers. However, they tend to charge higher borrowing costs for firms with CSR concerns (Goss and Roberts, 2011) and for those that pollute more (Reghezza et al., 2022). Moreover, Wang et al. (2021) find that CSR practices drive up the cost of equity in East Asia pointing the economies with weak investor protection as the main cause. Sustainability can affect the cost of financing through several channels. First, companies with long-term commitment to sustainability exhibit greater information transparency which results in less information asymmetry between the contracting parties (Hong and Kacperczyk, 2009; Dhaliwal et al., 2014), leading to a higher demand for banks’ stocks or bonds (El Ghoul et al., 2011). Being socially conscious induces a lower exposure to litigation risks, such as those related to employee benefits or environmental pollution, which can have a negative impact on future cash flows and impair the ability to fulfil outstanding obligations (Hong and Kacperczyk, 2009; Ge and Liu, 2015). Consequently, investors require a lower rate of return, whereas depositors in banks are willing to accept lower deposit rates. Second, ESG-focused firms have a stronger relationship with stakeholders, which generates moral capital (Godfrey et al., 2009). They can also benefit from a greater potential to attract customers, employees, and investors, take advantage of business opportunities tied to societal trends, avert regulatory intervention or environmental-related penalties (Edmans and Kacperczyk, 2022), and can identify a variety of risks, including strategic, operational, reputational, regulatory and financial with potential impact on future performance and enterprise value (Ng and Rezaee, 2015). Galletta et al. (2023) document that ESG-focused banks benefit from a reduction of their reputational risk. Third, as shown in previous studies (e.g., Neitzert and Petras, 2021), ESG ratings manifest a beneficial impact on companies’ idiosyncratic risk being a good risk-management approach. As a result, companies with higher ESG scores enjoy reduced costs of raising funds as compared to their riskier counterparts (El Ghoul et al., 2011; Agnese and Giacomini, 2023). 3 Degryse et al. (2023) find that green banks offered cheaper loans for environmental conscious firms only after the ratification of the Paris Agreement in 2015. 4 Sustainability and ESG performance are used interchangeably in this paper. Electronic copy available at: https://ssrn.com/abstract=4359454 In this paper, we examine the role of banks’ sustainability performance, i.e., the integration of ESG issues into financial decisions, on their funding costs. Using a sample composed of 493 in an international setting for a period spanning from 2003 to 2020, we document that an enhanced aggregate ESG rating is significantly associated with lower financing costs measured by the interest expense over interest-bearing liabilities (total cost of funds) and by the the ratio of interest expense on bank deposits to total deposits (cost of deposits). We find supporting evidence that all pillars that compose the ESG score are responsible for this outcome in the case of costs of raising interest-bearing liabilities, whereas for the cost of deposits the Environmental pillar appears to have an insignificant impact. Further, we show that only large banks and those from advanced countries benefit from transparency in the dissemination of ESG information in terms of funding costs reduction. The findings are robust across a variety of models and specifications, and across different sample structures. Our work relates to that of Azmi et al. (2021) highlighting no significant impact of ESG practices on the cost of debt for banks from emerging markets, and with Agnese and Giacomini (2023) investigating the role of sustainability on the cost of bond issuance by banks in the primary market in which the authors find that ESG-oriented banks from the European Union display cheaper funding costs, with the Governance pillar driving the results. Our work adds to existing literature in multiple ways. First, we extend the studies that analyze the impact of sustainability orientation of financial institutions on the cost of funds. Only few works focus on financial institutions, with inconclusive results (El Ghoul et al., 2013; Azmi et al., 2021; Agnese and Giacomini, 2023). Financial institutions, especially banks, play an important role in the financial system by providing loans to the real economy and by performing maturity transformation (Berger et al., 2020). Inefficient management of a bank or excessive risktaking could lead to a bailout using taxpayers’ money, hence the attention from the government, media, and academia (Wu and Shen, 2013). Second, our analysis focuses on the cost of debt capital performed separately for the overall cost of funds and deposit funding costs, which is distinct from the approach taken by most scholars who examine the impact of ESG performance on either the cost of equity or the cost of debt, which can vary greatly among banks due to differences in interest rates, debt maturity, and structure (Levine et al., 2021), without disentangling the role of deposits. Third, we contribute on the debate of the relevance of the stakeholder theory and find empirical evidence in favor of negative association between non-financial information disclosure and the cost of capital in banks. Electronic copy available at: https://ssrn.com/abstract=4359454 The rest of the paper is organized as follows: Section 2 describes the data and methodology employed, Section 3 presents the results and performs robustness checks, and Section 4 offers conclusions. 2. Sample, data, and empirical strategy 2.1 Sample and data Our dataset contains 493 publicly listed banks from 39 emerging and advanced economies covering 2003-2020 period. We started with all financial institutions included in the Refinitiv ESG Global Banking Services 5 index and selected only banks (712) based on Thomson Reuters Business Classification. Due to the availability of the data concerning ESG scores, bank-, banking system- and macroeconomic-level explanatory variables, we ended up with 493 banks with an average size of 152 billion USD at the end of 2020. Bank-specific characteristics are retrieved from the Refinitiv Eikon, whereas other control variables are obtained from the International Monetary Fund (IMF) and World Bank (WB). Following prior work (e.g., Aevoae et al., 2022; Agnese and Giacomini, 2023) we employ the ESG score, as well as its three dimensions, i.e., Environmental (encompassing Emissions, Innovation, and Resource use sub-pillars), Social (incorporating Community, Human rights, Product responsibility, and Workforce sub-pillars) and Governance (containing CSR strategy, Management, Shareholders sub-pillars) pillars, from the Refinitiv Asset4 database. These ten categories are derived from self-reported information disclosed by the banks and are weighted according to the number of issues they encompass to get the ESG Score. A higher ESG score indicates better sustainability performance. In addition, Refinitiv also reports the ESG Combined Score that considers 23 ESG controversy topics related to business ethics, anti-competition behaviors, accounting and reporting practices etc. ESG scandals are found to cause severe damage to a company's reputation and financial performance (Aouadi and Marsat, 2018). 2.2 Empirical strategy To test whether ESG performance influence banks’ funding costs we estimate the following model: πΆππ π‘ππ,π‘ = π½0 + π½1 × πΈππΊππ,π‘−1 + π½2 × πΏππ,π‘−1 + π½3 × ππ,π‘ +ππ + ππ‘ + πππ,π‘ 5 Ticker LA43GLBG. Electronic copy available at: https://ssrn.com/abstract=4359454 (1) where πΆππ π‘ππ,π‘ is the funding costs of bank i from country j in year t computed alternatively as Interest expense over Interest-bearing liabilities (total cost of funds) and Interest expense on bank deposits over Total deposits (cost of deposits) in line with Levine et al. (2021), πΈππΊππ,π‘−1 is the ESG Score, ESG Combined Score and the Environmental, Social and Governance pillars, respectively for bank i in year t-1, πΏππ,π‘−1 is a vector of lagged bank-level factors that are discussed in the literature to influence banks’ financing costs, i.e., Size (natural logarithm of total assets), Lending Activities (total loans/total assets), Capitalization (common equity/total assets), Credit Risk Ratio (non-performing loans/total loans), Profitability (net income/common equity), and Income Diversification (non-interest income/total revenue) (Ellul and Yerramilli, 2013; Levine et al., 2021; Azmi et al., 2021; Agnese and Giacomini, 2023), ππ,π‘ is a vector of banking system and macroeconomic control variables, i.e., Bank Concentration, Financial Institutions Index, Real GDP Growth, Yield to capture monetary policy stance (3-month government bond yield), and Slope to account for the impact of the unconventional monetary policy measures (difference between 10-year government bond yield and 3-month government bond yield) (Alessandri and Nelson, 2015; Levine et al., 2021; Azmi et al., 2021). ππ are bank fixed effects to capture bankspecific time-invariant heterogeneity and mitigate omitted variables bias, and ππ‘ are year fixed effects to account for aggregate time shocks common to all banks. Finally, πππ,π‘ represents the error term corresponding to bank i from country j in year t. We use cluster-robust standard errors to correct for any form of heteroskedasticity and autocorrelation in the residuals. Following Gambacorta and Shin (2018) all bank-level control variables are lagged one year to mitigate possible endogeneity issues. To reduce the potential influence of outliers, we winsorize all variables between 1 st and 99th percentiles. 3. Empirical findings 3.1 Descriptive statistics In Table A1 in the Appendix, we report the descriptive statistics of the variables used in the empirical analysis. As we can note, the average cost of funds was 1.79% ranging from 0.09% to 9.40%, with a standard deviation of 1.87%, whereas the cost of deposits is situated between 0.04% and 10.02%, with a mean of 1.49% and a standard deviation of 1.83%. Electronic copy available at: https://ssrn.com/abstract=4359454 Regarding the ESG score, it ranges from a minimum of 7.57 to a maximum of 88.31, with a mean of 45.53 and a standard deviation of 21.09. The ESG Combined Score has slightly lower values, with an average of 42.91 and a standard deviation of 18.70, with a minimum value of 7.57 and a maximum value of 84.73. 3.2 Empirical findings The benchmark results exhibited in Tables 1 and 2 show a negative and statistically significant at the 1% level association between the cumulative effect of Environmental, Social and Governance practices (ESG Score) and total cost of funds (interest expense/interest-bearing liabilities, Table 1, Model (1)) and cost of deposits (interest expense on bank deposits/total deposits, Table 2, Model (1)), respectively. The results remain consistent when we employ the ESG Combined Score, which accounts for specific controversies at the bank level derived from the international media sources, but with a reduced statistical significance. Thus, strong sustainability practices lead to lower fundings costs for banks, providing important evidence in favor of stakeholder theory. The results bear economic significance too: a one standard deviation increase in the ESG Score is linked with a decrease of 6.83% of a standard deviation in total cost of funds, whereas an increase of one standard deviation in the ESG Score leads to a decrease of 7.82% in the standard deviation of the cost of deposits. This is valid for all pillars of the ESG Score in the case of costs of interest-bearing liabilities and especially for the Social factor (social responsibility). Our results are consistent with those of Agnese and Giacomini (2023) who find a decrease in the cost of bond issuance for banks with strong ESG performance, but attribute it solely to the Governance pillar. Similarly, Eliwa et al. (2021) and Raimo et al. (2021) reach the same conclusion for non-financial corporations in terms of cost of debt financing. [Table 1 goes here] [Table 2 goes here] Our results could be explained by the following mechanisms: Banks can exhibit environmentally conscious behavior both internally and in their relations with clients and business partners (BΔtae et al., 2021).They contribute to environmental issues through (i) efficient use of resources, (ii) funding environmentally friendly projects, and (iii) lending less to customers that Electronic copy available at: https://ssrn.com/abstract=4359454 cause environmental damage (Gangi et al., 2019). Giannarakis et al. (2018) state that climate change disclosure is an useful instrument in reducing information asymmetry for both shareholders and stakeholders. This reduction in information asymmetry would ultimately attract more depositors (Azmi et al., 2021) and decrease the cost of financing. The purpose of the social performance is to showcase companies’ involvement with stakeholders (e.g., customers, employees, non-governmental organizations etc.), cross-industry partnerships and efforts towards community development, and is a tool in differentiating from their competitors and enhancing the public's view of their operations (Gangi et al., 2019; BΔtae et al., 2021), thus gaining moral capital (Godfrey et al., 2009). As a consequence, increased level of social transparency translates into lower cost of capital (Dhaliwal et al., 2014). Corporate governance mechanisms, in light of agency theory, plays an important role in aligning the interests of managers and shareholders (Grove et al., 2011). Effective corporate governance practices lower perceived risk and reduce information asymmetry, leading to a decrease in the cost of capital for companies (Ng and Rezaee, 2015).As concerning the cost of attracting deposits, we document that depositors do not value environmental commitments of banks, but rather their social performance and corporate governance quality. The estimated coefficients of control variables are consistent with previous literature on the factors affecting banks' funding costs (e.g., Arnould et al., 2022).Thus, banks’ total cost of funds is reduced by a funding structure that is mainly based on deposits, increased reliance on nontraditional sources of income, and larger GDP growth. On the other hand, well-developed financial institutions, more concentrated banking systems, and higher interest rates positively impact the cost of raising interest-bearing liabilities. As for the cost of attracting deposits, only larger share of deposits in total liabilities has a negative effect, while factors such as size, bank concentration, financial institutions index, and the yield on a 3-month government bond contribute to an increase in the cost of deposits. 3.3 Robustness tests To test the robustness of our fundings, we perform several robustness checks. First, we employ alternative estimation models. In Tables 3 and 4, Model (1), we include country fixed effects to account for country-level unobserved heterogeneity (bank fixed effects are dropped from the output because of collinearity). To control for any form of cross-sectional dependence, we estimate a regression with Driscoll and Kraay standard errors (Driscoll and Kraay, 1998) in Model (2). In Electronic copy available at: https://ssrn.com/abstract=4359454 this framework, the error term is presumed to be heteroskedastic, exhibiting autocorrelation up to a certain lag, and correlated between panels. This method can handle unbalanced panels and have better sample properties than other estimators, performing well even when the number of crosssection units exceeds the time dimension (Hoechle, 2007). [Table 3 goes here] [Table 4 goes here] Furthermore, in Model (3) we employ a dynamic estimator, i.e., the bias-corrected fixed effects (BCFE) developed by Everaert and Pozzi (2007) to capture the potential autoregressive structure of funding costs. The bias correction is applied through an iterative bootstrap algorithm and yields higher efficiency compared to Generalized Method of Moments (GMM) estimators (Everaert and Pozzi, 2007). Overall, the results maintain their significance regardless of the estimation method, both static and dynamic. Second, to make sure that results are not driven by the sample structure which is dominated by the US banks6, we exclude banks headquartered in the United States. As shown in Tables 5 and 6, Model (1), the main findings remain consistent. Next, we split the sample between advanced and emerging economies according to the IMF classification and perform the estimation from Eq. (1) separately. As presented in Tables 5 and 6, Models (2) and (3), only banks situated in advanced countries benefit from a sustainable behavior in terms of fundings costs reduction, whereas the results for those with the headquarter in emerging economies are found to be statistically insignificant, supporting the evidence of Azmi et al. (2021). Companies that operate in emerging markets face a number of challenges that affect their ESG performance given weak regulations, poor corporate governance, and lack of transparency (Khanna and Palepu, 2000). [Table 5 goes here] [Table 6 goes here] 6 Similarly, the sample used in Poursoleyman et al. (2023) is dominated by the US corporations: among 5410 firms, 2825 are domiciled in the United States. Electronic copy available at: https://ssrn.com/abstract=4359454 Large and small banks can be affected differently by their ESG disclosures given the fact that larger banking institutions benefit from the too-big-to-fail status (Anginer et al., 2018) and have a greater ability to diversify and gain access to capital markets as opposed to their smaller peers (Shim, 2003). We find that only large banks7 that are oriented towards ESG disclosure enjoy smaller costs of raising interest-bearing liabilities (Models (4) and (5)), whereas depositors value banks’ sustainability practices regardless of their size. 4. Conclusion This paper examines the nexus between banks' Environmental, Social, and Governance (ESG) practices and their funding costs in an international context, analyzing data from 493 banks across 39 countries from 2003 to 2020. We find that incorporating ESG practices into banks' financial decision-making has a beneficial impact on the cost of raising interest-bearing liabilities (total cost of funds) and the cost of deposits, providing further empirical evidence in favour of stakeholder theory. We further decompose the impact along individual ESG factors and show that all pillars contribute to cost reduction for interest-bearing liabilities, and only social performance and corporate governance quality matter for depositors. Moreover, the results indicate that only large banks and those located in developed countries benefit from increased transparency in the reporting of ESG information in terms of reduced funding costs.. Our findings bear important policy implications in terms of non-financial disclosure and banks’ funding costs as higher costs of raising capital are passed through into higher lending rates, thus reducing the credit availability to the real economy. 7 We define large and small banks based on the median size of total assets in USD as of 2020.
