This paper presents a comprehensive comparative review of digital banking regulations in Nigeria and the United States. The primary objective is to analyze and contrast the regulatory frameworks governing digital banking in these two countries, focusing on their impact on financial stability, consumer protection, and innovation in the banking sector. The methodology involves a detailed examination of existing literature, regulatory policies, and legal documents, complemented by interviews with key stakeholders in the banking industry. Key findings reveal significant differences in the regulatory approaches of Nigeria and the USA. Nigeria's regulations are more focused on promoting financial inclusion and mitigating systemic risks, reflecting the country's developing economic status and the need to address a large unbanked population. In contrast, the USA's regulations are more comprehensive and sophisticated, emphasizing consumer protection, data security, and maintaining a competitive market environment. The study highlights the challenges and opportunities presented by these regulatory frameworks, particularly in fostering innovation and adapting to emerging technologies in the banking sector. The conclusion underscores the importance of a balanced regulatory approach that safeguards consumer interests and financial system stability while encouraging innovation and competition. The paper suggests that both Nigeria and the USA can learn from each other's regulatory practices to enhance their digital banking ecosystems. This comparative review provides valuable insights for policymakers, financial institutions, and other stakeholders in the global banking industry, aiming to navigate the complexities of digital banking regulation in a rapidly evolving technological landscape.This paper presents a comprehensive comparative review of digital banking regulations in Nigeria and the United States.
