Financial system as a neural network of trust: A conceptual framework for financial stability

The increasing role of digitalization in the banking sector necessitates an in-depth analysis of the impact of information technology (IT) investments on bank profitability. The paper analyzes the influence of IT investments on the profitability of Vietnamese commercial banks. The data were collected from 27 commercial banks in Vietnam between 2010 and 2022. The methodology used in this paper is the Feasible Generalised Least Squares (FGLS) regression. The key results indicate that investment in IT has improved the overall performance of banks, as evidenced by an average increase of 1.8% in Return on Assets (ROA) and 15.3% in Return on Equity (ROE). In addition, the Equity-to-Asset ratio exerts a favorable influence on bank performance, increasing ROA by 15.7% and ROE by 40.9%. Furthermore, bank size also demonstrates a positive correlation with both ROA and ROE, raising it by 0.3% and 2.3%, respectively. Based on these findings, more efficient investment in digital transformation, collaboration with Fintech firms, IT competence enhancement for staff, and communication promotion for Vietnamese commercial banks are recommended. Enabling environments for bank digital transformation should be provided by the Government in building a centralized database and electronic systems, introducing fintech regulations, establishing digital ecosystems, and implementing security solutions.

Economic policy uncertainty has a profound impact on firms’ investment decisions, mainly in terms of increased risk and uncertainty for firms when planning future investments. This study aims to explore the impact of corporate economic policy uncertainty on corporate investment, as well as how corporate social responsibility disclosure moderates the relationship between economic policy uncertainty (EPU) and corporate investment. The analysis uses a sample of Chinese listed companies from 2010 to 2022, including 33,791 observations. The study uses ordinary least squares (OLS) regression with clustered standard errors. The basic and robust regression empirical results show that economic policy uncertainty has a negative impact on corporate investment. However, corporate social responsibility plays an important moderating role between them. The two-stage least squares method (2SLS) is used to solve the endogeneity problem of reverse causation. The heterogeneity results show that economic policy uncertainty significantly dampens business investment, while corporate social responsibility (CSR) is effective in mitigating this negative effect, especially among non-state-owned and low-cash-flow firms, where this moderating effect is more pronounced. The study concludes that as corporate social responsibility disclosure enhances information transparency and investor confidence, companies should prioritize CSR programs that ultimately help companies remain competitive and attractive to investors in volatile markets. Meanwhile, this also highlights the strategic importance of CSR in mitigating external risks, such as those presented through volatile economic policies.

Banking system is an important part of the financial system of each country. The operating efficiency in the commercial banking system will provide the tools and financial products more attractive and relevant to the needs of actors in the economy. The purpose of this paper is to analyze the impact of COVID-19 on the efficiency of 26 Vietnamese commercial banks. The paper uses a quantitative method with the nonparametric frontier analysis, data envelopment analysis (DEA) approach, to measure the efficiency of Vietnamese commercial banks. The paper adopts an intermediation approach as the banks are viewed as financial intermediaries providing financial services and payment services to entities in the economy. Research findings reveal that Vietnamese commercial banks have effectively leveraged the positive impacts of the COVID-19 pandemic, since the average efficiency in 2020 improved over the pre-pandemic period in 2019 on the same models for comparison and estimation. Based on such findings, the study makes some suggestions and recommendations to help Vietnamese commercial banks increase their operational efficiency in the context of the prolonged pandemic.
