Banking system stability in crisis periods: The impact of the banking regulator independence

Abstract

Local and global financial crises are caused by a wide range of geopolitical, macro-financial, and socio-economic determinants. The purpose of this study is to assess the role of central bank independence in preventing financial crises and mitigating their consequences. Two hypotheses were tested. A measure of the banking regulator independence is the CWN index of the central bank independence. The hypotheses were tested on data from 53 countries suffering from financial crises over the last 40 years (the sample includes both developed and developing countries from different continents). The tools of nonlinear logit regression (modeling the probability of loss of financial stability due to a financial crisis, considering different levels of the banking regulator independence) and panel regression with random effects (modeling the influence of the banking regulator independence on banking activities during crisis periods) were used for calculations. The study did not confirm that a high level of central bank independence is a necessary condition for preventing the occurrence of financial crises in the national economy. On the contrary, the likelihood of financial instability was found to be higher in countries with more independent central banks. Thus, during crisis periods, an increase in the CWN index by 1 ensures an increase in the regulatory capital adequacy parameter by an average of 0.28%, a decrease in return on assets by 0.59%, and an increase in the share of non-performing loans by 1.69%.
