The objective of commercial banks in Ethiopia is to make profits and thus satisfy the needs ofrntheir respective owners. The making of profits and even staying on board of thesernconventional banks depend on the strategies adopted by each bank to mobilize deposits fromrnthe public that is an input to earn income for most conventional banks. In order to make goodrnstrategies, however, the banks should know what factors determine the deposit mobilizationrnactivity in the real world. This paper empirically examines the determinants of commercialrnbanks deposit mobilization in Ethiopia for the periods 2003-2016. From total of eighteenrnCommercial Banks which are engaged in commercial bank activities, seven selected basedrnon the historical time formation of banks. The researcher adopted Quantitative researchrnapproach. Bank specific and macroeconomic variables were analysed by using thernbalanced panel random effect regression model. Different diagnostic tests (test forrnassumption of Homoscedasticity, Autocorrelation, Normality, average value of the error isrnzero and independent variables are non-stochastic) were conducted to check thernappropriateness of the model. The results reveal that Bank Profitability, Gross domesticrnproduct and liquidity are positively and statistically significant on bank deposit growth;rnwhereas, Exchange rate and credit risk is negatively and statistically insignificant on bankrndeposit growth. General inflation had insignificant positive influence on bank depositrngrowth. Since the depositor confidence increases if the commercial banks are profitable andrnhave adequate asset return, so commercial banks should sustain their profitability to increaserntheir amount of deposit. Commercial Banks should also increases their liquidity becausernhigher liquidity buffers tend to signal greater bank soundness, which could be a factorrnfavouring deposit demand. Finally the study suggests that as deposits are the criticalrnresource for investment, economic growth & development and also the banks are stayrnprofitable, they have to give more emphasis than ever to the activity. The Ethiopianrncommercial banks should have to introduce new deposit product types that are appealing tornthe public to increase market share. The government also should to give equal playingrnground for all banks.
