Turkey's competition authority has initiated an investigation into 65 companies within the auditing and financial advisory sector. The probe includes the Turkish operations of major global firms such as KPMG, PwC, Deloitte, and EY.
The authority is examining whether these firms engaged in anti-competitive practices, specifically concerning the coordination of service fees and labor market activities. The announcement prompted a negative reaction in Turkish financial markets, with the main banking index falling by 2% and the benchmark BIST 100 index declining by 1% on Wednesday.
This investigation introduces a level of uncertainty into Turkey's financial and corporate sectors. Scrutiny of major auditing firms, which play a crucial role in validating financial statements, could temporarily dampen investor confidence as the market awaits the probe's findings and potential consequences.
The investigation highlights a focus on regulatory compliance and fair competition within Turkey's professional services industry. Market participants will be closely monitoring the progress and outcome of the probe, as it could set a precedent for fee structures and talent acquisition in the sector.
