Audit failures, regulatory gaps, and the erosion of public trust in financial reporting have
raised global concerns about the effectiveness of audit oversight. This study investigates the
effect of audit regulatory frameworks on corporate reporting quality, using Nigeria as a
contextual anchor among emerging markets. It draws on global standards, theoretical models,
and empirical findings to explore the conceptual foundations, international perspectives,
practical challenges, and policy implications of audit regulation in enhancing auditor
independence, professional competence, and financial statement credibility. The findings
reveal that while regulatory frameworks have improved audit transparency and internal
governance in several economies, their effectiveness remains limited in regulatory authorities
with weak enforcement capacity. The study concludes that audit regulation must be globally
benchmarked yet locally responsive, emphasizing risk-based supervision, auditor competence,
and proactive oversight. It recommends empowering national regulatory institutions such as
the Financial Reporting Council of Nigeria (FRCN), adopting AI-enabled audit systems,
mandating firm rotation, and enforcing sanctions for non-compliance. These measures are
essential for strengthening audit reliability, improving disclosure quality, and rebuilding
stakeholder trust across diverse economic settings
