This study examines the role of behavioral interventions specifically digital nudges in promoting financial inclusion through digital financial services (DFS) in developing economies. As the adoption of DFS increases, behavioral barriers such as low awareness, trust deficits, and habitual resistance continue to hinder effective use, especially among underserved segments. Using survey data from 500 respondents across urban and semi-urban areas, the research analyzes the impact of different nudge formats visual, audio, and gamified on digital financial behaviors such as mobile payments, savings, and bill payments. Findings indicate that gamified and visual nudges significantly enhance engagement, particularly among younger users. Audio-based nudges were effective in prompting immediate actions, especially among older adults and those with lower digital literacy. The study further reveals that trust in the digital system, emotional appeal, and cultural alignment are critical in shaping user responses. Women in rural settings, for example, showed stronger engagement when nudges reflected empathy and cultural sensitivity. These results emphasize the importance of designing inclusive, context-aware interventions. While the study offers useful insights, it has limitations. It relies on self-reported data, which may be subject to biases, and uses a cross-sectional design, limiting causal interpretation. The geographic focus may also constrain the generalizability of findings. Despite these constraints, the research contributes to a growing body of literature advocating for the integration of behavioral insights into digital financial inclusion strategies. It highlights the need to move beyond infrastructure development toward more user-centered approaches that consider emotional and psychological drivers of financial behavior. Such interventions can foster greater trust, participation, and long-term engagement in digital finance, supporting broader goals of inclusive economic growth.
