This chapter examined the role of financial technology (fintech) in shaping the operations of non-bank financial intermediaries (NBFIs). It investigated key areas such as operational efficiency, credit expansion, financial inclusion, and shifts in market structure driven by technological advancements. Additionally, the chapter highlighted the growing cyber risks associated with fintech adoption, including data breaches and unauthorized access to sensitive financial data, which pose significant threats due to the high-value information held by NBFIs. The discussion extends to the implications for global regulatory frameworks, particularly concerning anti-money laundering (AML) and counter-terrorism financing (CTF) measures. Through a comprehensive literature review, the chapter assessed how cybersecurity vulnerabilities in NBFIs could potentially destabilize the broader financial ecosystem. The findings aim to inform policymakers and industry stakeholders on balancing innovation with risk mitigation in an increasingly digital financial landscape.
