This dissertation intends to investigate Capital Adequacy Ratio (CAR) determinants in commercial banks in the Middle East and North Africa (MENA) Region along with categorizing the countries based on income levels. The dissertation identifies the determinants of CAR, for dependent variable, Credit quality (CRQ), Size (SIZE), Liquidity (LIQ), Profitability (PR) and Operations efficiency (NIM), which are being used as bank specific independent variables in addition to Gross Domestic Products Growth rates (GDPR) as macroeconomic independent variable.
The sample includes 115 commercial banks which have been analyzed over the period from 2011 to 2019. The dissertation highlights the significant independent variables, which affect at most one CAR out of nine within MENA countries commercial banks.
The dynamic multiple regression model is employed using Generalized Method of Moments (GMM) with fixed effects through E-views software. The researcher also highlights the significant determinants of CAR in subcategorized countries based on their income levels, which are Three groups namely High Income countries, Upper Middle Income countries and Lower Middle income countries (Egypt).
The results revealed a contradiction between categorized countries in terms of the variables that are significant. However, profitability is a common independent variable that has significance over all the subcategories of countries within analyses. It’s also worth noting that the CAR is significantly determined by the macroeconomic variable in upper-middle income countries only.
