This study aims to fill the gap in the literature by specifically investigating the impact of country risk on the credit risk of the banking sectors operating in Brazil, Russia, India, China, and South Africa (BRICS), emerging countries. More specifically, we explore whether the country-specific risks, namely financial, economic, and political risks significantly impact the BRICS banking sectors’ non-performing loans and also probe which risk has the most outstanding effect on credit risk. To do so, we perform panel data analysis using the quantile estimation approach covering the period 2004–2020. The empirical results reveal that the country risk significantly leads to increasing the banking sector’s credit risk and this effect is prominent in the banking sector of countries with a higher degree of non-performing loans (Q.25 = − 0.105, Q.50 = − 0.131, Q.75 = − 0.153, Q.95 = − 0.175). Furthermore, the results underscore that an emerging country’s political, economic, and financial instabilities are strongly associated with increasing the banking sector’s credit risk and a rise in political risk in particular has the most positive prominent impact on the banking sector of countries with a higher degree of non-performing loans (Q.25 = − 0.122, Q.50 = − 0.141, Q.75 = − 0.163, Q.95 = − 0.172). Moreover, the results suggest that, in addition to the banking sector-specific determinants, credit risk is significantly impacted by the financial market development, lending interest rate, and global risk. The results are robust and have significant policy suggestions for many policymakers, bank executives, researchers, and analysts.

Countries encounter conflicting policy options in reaching fast development goals due to high resource use, rapid economic expansion, and environmental degradation. Thus, the present research examined the connection between CO₂ emissions and urbanization, globalization, hydroelectricity, and economic expansion in China utilizing data spanning the period between 1985 and 2018. The novel quantile-on-quantile (QQ) and quantile regression (QR) approaches were applied to assess this interconnection. The QQ approach is characterized by its ability to incorporate quantile regression fundamentals and non-parametric estimation research. As a result, the method appears to transform the quantile of one parameter into another. The QQ outcomes revealed that in all quantiles (0.1–0.95), gross domestic product (GDP), urbanization, and globalization trigger CO₂ emissions in China, while in each quantile (0.1–0.985), hydroelectricity consumption mitigates CO₂ emissions. The QR outcomes also affirmed the outcomes of the QQ regression estimates. Policies are suggested based on these findings.

The present study particularly aims to probe the quadratic effects of the combined and individual sovereign environmental, social, and governance (ESG) activities on the banking sector’s profitability. Furthermore, we attempt to shed light on the channels through which sovereign ESG practices impact the banking sector’s profitability. Unlike the vast majority of prior works that investigated the sustainability practice–firms’ profitability nexus from the firm level, this study originally probes this relationship from the country level by considering the sovereign ESG sustainability activities. To attain this purpose, we focus on banking sectors operating in Gulf Cooperation Council (GCC) economies and employ the panel-fixed effects and panel-corrected standard errors approaches between 2000 and 2022. Remarkably, the findings uncover that the nexus between combined sovereign ESG and profitability is a non-linear and inversed U-shape (concave), implying that investing in sovereign ESG enhances the banking sector’s profitability. However, after exceeding an inflection point (0.349), its effect turns out to be negative and it develops into activities of destruction. Furthermore, the findings underscore that the association between individual sovereign environmental responsibility and the banking sector’s profitability is a non-linear U-shape (convex), while an inversed U-shaped (concave) nexus is uncovered for the individual sovereign social and governance activities. Moreover, the significant non-linear inverted U-shape for the combined sovereign ESG–stability nexus corroborates that financial stability is a channel through which sovereign ESG significantly impacts profitability.

Extant literature suggests that the banking sector’s sustainability is achievable by minimizing the risk factors, in particular, credit risk (CR). Despite prior studies, there are fewer attempts to considerably probe the role of country governance settings in managing CR and ultimately achieving sustainability. Therefore, this study aims to test this nexus for the banking sector operating in BRICS developing economies. Specifically, this research attempts to explore whether country governance has a moderator role between CR and the exposure of environments to risk factors. To achieve these objectives, we conduct panel data analysis using the quantile (QR) and fixed effects (FE) estimation methods. The results show that increasing liquidity, profitability, capital requirements, and income diversification lead to decreasing CR, whereas increasing inefficiency causes an increase in CR. In addition, the results reveal that a country’s increasing vulnerability to a specific financial risk index (FRI), economic risk index (ERI), and political risk index (PRI); developing capital markets; increasing lending interest rates; and weakening country governance quality is significantly linked to increasing CR. Remarkably, the results underscore that country governance has a significant moderator role, and by enhancing the quality of country governance, the impact of country-specific FRI, ERI, and PRI on CR could be attenuated.

The novel COVID-19 virus, and the pandemic that has followed its spread, has had a massive impact on the banking industry on a global level. Therefore, considering this context, this study examines the effect of the COVID-19 pandemic on the banking sector’s performance in the Asian emerging economics, over a time span ranging from 2016Q1–2021Q2. For this purpose, this study makes use of the FE, RE, 2SLS, and PPML regression models. The empirical findings show that the GDP and banking size are positively related to bank performance in the pre-COVID era, and the COVID pandemics era thus far in the Asian emerging economies. In addition to this, the findings also reveal that the impact of GDP and bank size on banking performance is lower in the pandemic period, as compared to the pre-COVID period. Furthermore, the results show that the COVID pandemic has significantly affected the banking sector performance in the Asian emerging economies. Findings have also suggested that the central bank should shift their focus on the banking industry in the Asian emerging economies. Various other policy implications have also been suggested under the present study.

Despite earlier research on green energy, there is still a significant gap in understanding how energy-related uncertainties affect renewable energy consumption (REN), especially in developed nations. Thus, this study explicitly looks into how the energy-related uncertainty index (EUI) can promote (or diminish) REN in sixteen wealthy nations between 2000 and 2020. Furthermore, we attempt to specify the factors of REN and explore whether environmental policy stringency (EPS) and global economic policy uncertainty (GEPU) could help moderate (or intensify) the EUI-REN nexus. To achieve this, we employ different panel data methods. The results underscore that the EUI significantly impacts REN, denoting that higher uncertainties related to energy markets lead to promoting REN. Additionally, the (EUI × EPS) underlines that EPS has a favorable role in increasing the positive effect of the EUI on REN in sample developed countries while (EUI × GEPU) has a detrimental effect. Remarkably, the findings underline that the effect of the EUI on REN is more positive in high EPS countries and that the positive effect of the EUI is more moderate when GEPU is high. The findings also underscore that the development of the financial market, FDI, personal remittances, and EPS positively stimulate REN whereas CO₂, total natural resources rents, economic activity, and GEPU have a detrimental impact. The results are robust, and authorities and policymakers are advised to implement a wide range of policy proposals to accomplish sustainable development goals (SDGs) 7 and 13.
