Determinants of bank capital adequacy: Empirical insights from Arab countries

This paper examines the macro-economic and bank-specific factors affecting non-performing loans in commercial banks. Using 47 listed commercial banks from six countries, namely 19 banks from Nigeria, 14 banks from Benin, 3 banks from Burkina Faso, 3 banks from Gambia, 3 banks from Guinea, and 5 banks from Liberia for the period 2008 to 2019, fixed and random effect model was used. The Hausman test favored the selection of fixed effect model, and it was found from the estimation that the liquidity ratio, capital adequacy ratio and inflation rate significantly affect non-performing loans. As a result, it is advised that banks depend not only on their ability to achieve the capital adequacy ratio, but also guarantee that loans are thoroughly scrutinized before being issued to beneficiaries. Bank managers should guarantee that banking staff is not simply awarding loans to secure their jobs by accumulating deposits from consumers at the price of the bank’s long-term stake. In addition, the economies of West Africa should keep their inflation rates low so that repayment of loans on time is cheap and realistic.

Capital stability of the banking system is the basis of its effective development and realization of its main function – optimal redistribution of capital. So, the aim of the article is to develop indicators of capital stability of the banking system, and to propose the frameworks for the long term capital stability strategy of the banking system in Ukraine. For this purpose, the analysis of micro- and macroeconomic indicators of the capital stability of domestic banks within the period 2007–2016 is made. To carry out the research, there were used the statistic data of the National Bank of Ukraine, its legislative and regulatory documents, the Basel Accords.

Capital stability of the banking system has been defined in the article as the process of ensuring capitalization that is adequate to the banking risks and cyclical economic development. It has been detected that a significant reduction in return on equity of the Ukrainian banks in 2014–2015 even with restoring their liquidity has had a crucial destabilizing impact on their capital stability. In order to improve the assessment of capital stability, its key indicators for the groups of domestic banks have been studied. The necessity of refocusing macroprudential requirements of the National Bank of Ukraine from quantitative indicators to qualitative ones to ensure economic development has been proved. It has been concluded that a necessary condition for restoring the Ukrainian banking system was to develop an effective strategy for ensuring its capital stability, which should be focused on the creation of its diversified structure.

Sustainable firm value is the central concept for corporations, including the banking industry. This study examines the effect of profitability and bank size on firm value through capital structure. This study surveyed six banks registered in BUKU 4-member commercial banks operating in Indonesia that have been listed on the Indonesian Stock Exchange and implemented digital banking practices from 2007 to 2019. The six banks are Bank Mandiri, Bank Rakyat Indonesia, Bank Negara Indonesia, Bank Central Asia, Bank CIMB Niaga, and Bank Panin. Data collection is carried out by tracing the banks’ reports from the Bloomberg system terminal. Data analysis used a two-stage least squares technique. The results showed that profitability negatively and significantly affected the capital structure with a coefficient of –0.374. Moreover, bank size influences the capital structure with a negative coefficient value of –0.334. In addition, profitability positively affects firm value with a coefficient value of 0.387. Furthermore, bank size influences capital structure with a beta coefficient value of 0.158. Finally, the bank size affects firm value with a coefficient value of –0.419. These findings provide an insight for bank management to enhance firm value by assessing profitability, bank size, and capital structure. This study also contributes to the ongoing research in financial management.
