The emergence of Social Media revolution in this present era has not only transformed customer's routine behavior but has also influenced their demand and expectation patterns from their financial partners resulting in the evolving paradigm shift from traditional banking system to Social Media banking (SMB). The growing popularity of Social Media and their increasing adoption rate by financial institutions in different parts of the world lays the foundation for this study. This study focuses on the acceptance and use of Social Media banking in the Sultanate of Oman, which is witnessing remarkable economic and technological development in the past few years. For this study, the different dimensions of Unified theory of acceptance and use of technology (UTAUT) is assessed and studied with the help of a developed structured undisguised questionnaire comprising scales and is administered among existing users and potential users of Social Media banking in Oman. The data collected was analyzed with the help of analytical tools like SPSS and PLSSEM. It was found that Effort Expectancy (EE) has the highest significant influence on Behavior Intention (BI) towards SMB followed by the significant influence of Behavior Intention(BI) on Usage Behavior(UB) of SMB. Social Media provides an extensive platform for banks to connect to people located at diverse geographic locations, share their information and improve relationship with customers. Thus this study will form a framework for research and development in this sector, which will benefit not only banks and customers, but also other financial institutions.
