PurposeFinancial inclusion aims to provide affordable financial services, including banking, loans, equity, and insurance products, to underserved populations. This study aims to examine the moderating effect of a bank’s capital adequacy ratio (CAR) on the nexus between financial inclusion (FI) and a bank’s financial performance (FP) in the Egyptian setting.Design/methodology/approachThe study uses two empirical linear mixed models (LMM) to test the moderation effect of a bank’s CAR on the association between FI and FP. The study sample comprises 360 bank quarter-observations of 10 listed banks in the Egyptian Stock Exchange (EGX) from 2013 to 2021.FindingsThe findings show that the bank’s CAR strengthens the association between FI dimensions, namely, deposit growth, loan growth, and the number of employees, and the bank’s FP with contradicted directions.Research limitations/implicationsThis study provides policymakers insights into the crucial role of complying with banking regulation, namely, the capital adequacy ratio (CAR) and expanding financial inclusion practices to enhance and improve the bank’s FP. Thus, encouraging more strategies and facilities toward financial inclusion.Originality/valueDue to the scarcity of financial inclusion literature in emerging economies, this paper extends FI literature by highlighting the moderation impact of a bank’s CAR on the relationship between FI dimensions and FP in the Egyptian banking sector. Consequently, this study clarifies this beneficial relationship, which may have significant implications for restoring the challenges faced by the Egyptian economy following the critical events it went through, which, in turn, impacted the country’s poor and vulnerable.
