Financial Technology, commonly referred to as FinTech, has become a major force transforming the global financial services sector. The integration of advanced technologies such as artificial intelligence, blockchain technology, big data analytics, and mobile-based platforms into financial services has altered the manner in which banking activities are conducted. Traditional banking institutions, which earlier depended heavily on branch-based operations and manual procedures, are increasingly compelled to adopt digital solutions in order to remain competitive. This study critically evaluates the influence of FinTech on conventional banking practices. It explores the opportunities generated by technological innovation, including increased operational efficiency, wider financial inclusion, and improved customer service experiences. At the same time, the study highlights several challenges associated with the growing role of FinTech, such as cybersecurity threats, regulatory complexities, and intensified market competition. The analysis suggests that although FinTech has significantly disrupted traditional banking models, it also opens avenues for strategic partnerships and technological collaboration between FinTech firms and conventional banks, ultimately contributing to the evolution of the modern financial ecosystem.
