This study looked at how FinTech helps promote gender equality in Nigeria’s financial sector. It focused on how financial rules and policies support women’s access to money and banking services. Around the world, more people now use financial services. But women in developing countries like Nigeria still face many challenges. FinTech offers new ways to access money. It helps women overcome barriers like cultural rules and lack of access to banks. The study reviewed important Nigerian policies such as the National Financial Inclusion Strategy and the National Gender Policy. It used different theories like Diffusion of Innovation, Gender Empowerment, and Financial Intermediation. These helped explain how FinTech can support women and help them earn and save money. The study also pointed out some problems. These include low digital skills and strong cultural beliefs that limit women’s use of FinTech. The findings led to suggestions for better financial systems that include and support women. This is important for fairness and for Nigeria’s economic growth.
