Artificial intelligence (AI) is transforming the dimension of financial technology, also known as fintech, by automating procedures, boosting risk assessment, increasing user experience, and making transaction-level fraud detection easier to carry out in real time. Nevertheless, the speedy adoption of AI by the finance sector has raised a lot of concerns on ethical AI governance, data privacy, AI decision-making bias, cybersecurity threats, and regulatory compliance. If poorly regulated, AI in fintech presents prospective risks of financial instability, privacy abuses, and discriminatory lending. This chapter focuses on a framework for responsible AI adoption in which regulators, financial organizations, and AI developers can ensure AI deployment meets ethical, transparent, and accountable standards when deploying with similar technology in fintech. It examines trends in AI adoption in Europe, North America, Asia, Africa, and Latin America as well as best practices from around the world. It also examines strategies for algorithmic transparency, regulatory compliance, and AI risk mitigation. It also talks about global regulatory harmonization, XAI (explainable AI), and ethical AI framework needed for a trustable AI in finance.
