The rising number of financial frauds are expected to propel the growth of the audit and assurance services market going forward. Financial frauds are intentional acts of deception carried out for financial gain, typically involving misrepresentation, manipulation, or concealment of financial information.

Financial frauds drive the demand for audit and assurance services as organizations depend on auditors to independently review financial statements, identify discrepancies, and improve internal controls to detect and prevent fraudulent activities. For instance, in October 2025, according to the Central Bank of Ireland, an Ireland-based national central bank, Irish resident Payment Service Providers (PSPs) reported $173 million (€160 million) in fraudulent transactions in 2024, marking a 24.5% rise compared to $139 million (€129 million) recorded in 2023.
