With an emphasis on compliance, risk management, and internal control systems, this research examines the broad framework of banking rules that oversee banks' financial operations. The report highlights the significance of reconciliation methods, regulatory compliance, and operational control across several regions through an internship at ANZ. It offers information on statutory ratios, capital adequacy standards, the Reserve Bank of India's directives, and regulatory acts such as the Prevention of Money Laundering Act of 2002 and the Banking Regulation Act of 1949. ANZ data analysis is also included in the research, outlining patterns in the company's financial performance, difficulties with regulatory compliance, and tactical recommendations for long-term banking operations.
