Mobile banking services have gained popularity among smallholder farmers in northern Ghana as a means to manage financial transactions and access credit. However, there is limited research on how these services influence financial literacy. The study will employ a qualitative approach, drawing on existing literature and expert interviews to develop a comprehensive theoretical model that can guide future empirical research. This theoretical model provides a robust foundation for understanding how mobile banking can enhance financial literacy among rural populations, thereby facilitating sustainable agricultural practices. Future research should incorporate longitudinal studies to measure long-term impacts and evaluate the effectiveness of different mobile banking platforms in northern Ghana.
