The impact of financial crime regulations on corporate governance: A critical analysis of U.S. SEC, PCAOB, and global anti-fraud policies

Financial crimes such as fraud, corruption, and misreporting continue to threaten corporate integrity, investor confidence, and the stability of global financial markets. In response, regulatory bodies in the United States—particularly the Securities and Exchange Commission (SEC), the Public Company Accounting Oversight Board (PCAOB), and landmark legislation such as the Sarbanes-Oxley Act (SOX) and the Foreign Corrupt Practices Act (FCPA)—have implemented robust frameworks to strengthen corporate governance and fraud prevention. This paper critically analyzes how these U.S. financial crime regulations have transformed corporate oversight mechanisms, improved accountability, and shaped global compliance standards. It also examines how international anti-fraud policies increasingly align with U.S. practices, fostering cross-border regulatory synergy. Through a review of legal frameworks, enforcement cases, and corporate responses, this study highlights the positive influence of these regulations on internal controls, board governance, and ethical conduct in multinational corporations. The paper concludes by offering policy recommendations to enhance compliance effectiveness and promote ethical business practices in a dynamic global environment.
