The increasing instances of financial fraud are expected to propel the accounting and auditing markets in the coming years. Financial fraud involves deceptive or unlawful activities carried out with the intention of misleading others for monetary gain. Accounting and auditing help identify and prevent financial fraud by offering oversight, ensuring regulatory compliance, performing detailed reviews of financial records, and implementing internal controls to reduce the risk of fraudulent practices. For example, in March 2024, data from the Internet Crime Complaint Center (IC3), a US-based federal agency for reporting cyber-enabled crime, showed that internet crime losses rose to $12.5 billion in 2023 from $10.3 billion in 2022, driven by 880,418 reported complaints. As a result, the growing prevalence of financial fraud is driving the accounting and auditing markets.

Leading firms within the accounting and auditing industry are increasingly incorporating Internet of Things (IoT) and blockchain technologies into their auditing solutions. These technologies are used to enhance the precision of data, boost transparency, streamline audit processes, and improve fraud detection. In February 2023, Ernst & Young Global Limited introduced the latest version of their EY Blockchain Analyzer, now including features such as bulk reconciliation of non-blockchain records with public ledgers and extended support for additional cryptocurrencies such as Dogecoin. The adoption of IoT and blockchain not only ensures better data reliability and traceability but also raises the demand for audit services among sectors leveraging these advanced technologies.
