Auditor Independence


We examine how the World's Audit Oligopoly impacts competition, audit fees, and quality, noting that competition has weakened, and regulatory bodies hesitate to impose strict penalties. The industry’s vulnerability persists, especially due to legal risks. Until smaller firms can grow to rival the Big Four, multinational corporations will have limited auditor options. We further discuss barriers for new competitors, past anticompetitive behaviours, and regulatory needs to prevent recurrence. The industry’s business model is set for an overhaul with the government expected to clarify which services an auditor can and cannot provide. Despite concerns, the Big Four's market dominance and some liability protections suggest they may not be the "weakest" oligopoly worldwide.
