Exploring the bearing of liquidity risk in the Middle East and North Africa (MENA) banks

Abstract

AbstractThe paper examines how liquidity risk affects the Middle East and North Africa (MENA) bank profitability. Banks need profitability to survive, but liquidity risk measures long-term company health. Through Refinitiv Eikon, quantitative data was collected over 11 years from 2012 to 2022 for 71 MENA banks to support the theoretical study. Return on Equity (ROE), a profitability indicator, is the dependent variable, whereas liquidity risk is the independent variable and controlling for size, loan quality, inflation, gross domestic product, income diversification, operational efficiency, capital adequacy, and growth. This study estimates the impact of liquidity risk on MENA bank profitability using OLS and panel regression (fixed and random effects). Several results were found, such as that bank size, operational efficiency, and non-performing loans negatively affect profitability, suggesting that large banks have higher operating costs and may weaken profitability in MENA. Besides, additional non-performing loans increase the bank’s costs and thus diminish profitability. Also, if the bank has no control over the operational expenses, then this will lead to reduce profitability. Liquidity risk, capital adequacy, income diversification, and growth have a positive significant impact on ROE implying that banks with higher growth opportunities, better capital adequacy ratio, more income sources, and liquidity risk will result in higher profitability as explained by the risk-reward theory. The results are robust and this has been confirmed by applying the Generalized Method of Moments (GMM).
