Technology has been the key driver of change in how the banking industry operates by complementing services offered, such as check books, ATMs, voicemail/landline interfaces, smart cards, pointof-sale networks, and internet resources. Such services subsequently influence person to person (P2P) mobile money transfer (MMT), pay bill services, loan to customers and access to a wide range of banking services e.g. a/c balances, mini statements, transfer of money from one's mobile line a/c to one's own bank account. All these have the aspects of market share and financial performance of commercial banks. This study sought to determine the influences of mobile fund transfers on the financial performance and market share of commercial banks. The objectives of the study was to examine how various mobile money services transactions' impact on the performance of commercial banks; establish the effect of accessibility to mobile money services and finally determine the effect of efficiency and proficiency of mobile money services on the performance of commercial banks. The study adopted a survey study. The target population of the study was the 11 listed banks. The key study instruments used to collect primary data were questionnaires. Quantitative analysis was analyzed through descriptive statistics such as measure of central tendency that generated relevant percentages, frequency counts, mode, and median and mean where possible. To test for the strength of the model and the effects of mobile banking on the financial performance of commercial banks in Kenya, the study conducted an Analysis of Variance (ANOVA). From the regression model, the study found out that there were fund transfer variables influenced positively the financial performance of commercial banks in Kenya. The study found out that the intercept was 1.076 for all years. The independent variables that were studied explain a substantial 75.1% of financial performance of commercial banks in Kenya as represented by adjusted R2 (0.751). The study therefore concludes that mobile banking fund transfer positively and significantly affects the financial performance and market share of commercial banks in Kenya. The findings revealed that many mobile banking products are being offered by banks such as Fund Transfer between Accounts/ E-funds transfer, Bill Payment, order for cheque books and bank statements and therefore concluded that the financial performance of the banks that provide these mobile banking products has improved because they ensure efficiency of the banking services. The study recommends that policy makers consider mobile banking in their formulation of policies because of the technological developments and the expected switch from physical branch networks to technologically supported banking services. The study further recommends that commercial banks keep adopting and using mobile banking in their operations because the number of people with access to a mobile hand set is increasing every day.
