The purpose of this article is to examine the impact of the shock increase, in the value of nonperforming loans, on the equity level and profitability of 141 banks in 18 countries of Central Eastern South Europe (CESE). This study is important for assessing the financial stability of banks in this region in the face of the continuing negative effects of the COVID-19 pandemic. Based on the annual data, as of the end of 2020, from the S&P Global database, stress tests were carried out to check what value of NPL growth, over the next year, will lead to breach the regulatory capital requirements in domestic sectors and in individual groups of banks. The results indicate that the banks in CESE were well capitalized and had the ability to maintain capital requirements with a 12% increase in nonperforming loans. The resilience of domestic banking sectors varies, and it is higher in non-EU countries. Smaller and non-public banks show a greater ability to preserve the appropriate level of equity, although there is a risk that they may postpone the time of provisioning credit risk and additionally increase lending to lower the NPL ratio. Larger banks are more profitable in times of crisis. The results of the research are important for assessing the stability of the banking sector in CESE during the crisis and can be used by financial supervision of the region’s countries and banking market analysts.

The importance of the question about the relationship between concentration and efficiency lies in the fact that banks’ efficiency affects ability to extend loans and ensure financial stability of the banking sector. The study examines this relationship on the example of 150 banks operating between 2005 and 2019 in 11 EU and 8 non-EU countries from the SECE region. The value of profit efficiency was assessed with the stochastic frontier approach, and next regressed with the banking market concentration and bank specific and macroeconomic explanatory variables. The results for the entire sample as well as for domestic and foreign-owned banks indicate that concentration positively and nonlinearly impacts bank efficiency, both in EU and non-EU countries. Moreover, the size of a bank and income diversification help to improve efficiency of banks in the SECE region. The study shows that banks in SECE countries seem to follow the efficient structure hypothesis.

Research background: The contribution of banks? non-interest income to the total income becomes particularly important in the face of a severe financial crisis, usually accompanied by burdensome restrictions in economic activity, insolvencies of enterprises and households and low interest rates of central banks. Purpose of the article: This study investigates banks in 40 European countries to determine whether non-interest income had a significant impact on the bank?s profitability and whether the severity of the COVID-19 pandemic influences the form of this relationship. Methods: This study used a linear cross-section model using bank-level data. In the model, the bank?s profitability was regressed with the measure of income diversification, controlling for the pandemic?s intensity and the state of the country?s economy and bank characteristics. Banking data were obtained from the S&P Global MI. The Oxford COVID-19 Government Response Tracker (Hale et al., 2021, pp. 529?538) was the source of pandemic-related variables. Findings & value added: The obtained results indicate that the increases in non-interest income share in the bank?s total income have a statistically significant positive impact on profitability for the European banking sector. The dependence of profitability on diversification was stronger with the growing adverse effects of the pandemic. Our results are in line with those for the US banks (Li et al., 2021) and the European Central Bank Banking Supervision?s assessment that higher non-interest income has allowed banks? profitability in the euro area to be maintained at a pre-pandemic level (ECB, 2021). In addition, the study contributes to previous literature by testing the impact of the severity of the COVID-19 pandemic on the relationship between income diversification and bank profitability in 40 European countries.

The main objective of this article is to test the relationship between the intensity of CO₂ emissions and company’s cost of debt capital. This study fills a gap in the financial literature on this compound by examining a sample of 225 large nonfinancial enterprises operating in 15 EU countries in the years 2018–2021. The fractional logit regression controlling for company’s characteristics (assets, profitability, liquidity and leverage) was used. The results show that by reducing the intensity of CO₂ emissions, a company can reduce the cost of debt. This relationship was confirmed for three measures of intensity, i.e., CO₂ emissions in relation to revenues, assets and number of employees. Markets and financial institutions impose an additional risk premium in relation to companies operating in an industry considered to be comprised of strong CO₂ emitters. The use of the latest data for a wide sample of European enterprises provides an up-to-date assessment of the analyzed issues and the results can be used by enterprises and public authorities when analyzing the benefits of implementing a technology that reduces CO₂ emissions.

Summary: Subject and purpose of work: The aim of the article is to present selected aspects of the digitization process of the banking sector in Poland, including the role of the digital channel in the sale of banking products. Materials and methods: The research is of comparative character and is based on data from the financial website PRNews.pl, NBP, KNF and the ECB Bank. Results: Mobile banking in Poland is highly concentrated. In 2016-2019, the five largest banks serviced 82% of all mobile banking customers, and their number increased by 27% annually. Conclusions: Digitization simplifies the process of obtaining and processing information and contributes to reducing operating costs. However it also forces banks to prepare appropriate security and implement costly technological investments. It increases the availability and quality of banking services, and moves customer service from banking branches to the digital channel. Additionally it contributes to reducing the network of branches and the number of employees employed in them.
