TL;DR

This paper examines how Artificial Intelligence (AI) and Machine Learning (ML) are transforming finance by enabling hyper-personalized services, real-time fraud detection, and operational efficiency across retail banking, wealth management, and corporate finance. The study demonstrates that AI/ML integration enhances decision-making, reduces risk, and improves customer experience—provided ethical and regulatory frameworks are prioritized.

ABSTRACT

With rapid transformation of technologies, the fusion of Artificial Intelligence (AI) and Machine Learning (ML) in finance is disrupting the entire ecosystem and operations which were followed for decades. The current landscape is where decisions are increasingly data-driven by financial institutions with an appetite for automation while mitigating risks. The segments of financial institutions which are getting heavily influenced are retail banking, wealth management, corporate banking & payment ecosystem. The solution ranges from onboarding the customers all the way fraud detection & prevention to enhancing the customer services. Financial Institutes are leap frogging with integration of Artificial Intelligence and Machine Learning in mainstream applications and enhancing operational efficiency through advanced predictive analytics, extending personalized customer experiences, and automation to minimize risk with fraud detection techniques. However, with Adoption of AI & ML, it is imperative that the financial institute also needs to address ethical and regulatory challenges, by putting in place robust governance frameworks and responsible AI practices.
