Ergun was detained for questioning on October 31 before his arrest was announced Tuesday. The investigation concerns suspected manipulation involving investment funds and listed shares, according to Bloomberg. Borsa Istanbul had already replaced Ergun on an interim basis, appointing Deputy CEO Atila Tureli as acting chief executive on November 1.

Investigation reaches senior financial officials

Ergun is the highest-ranking official arrested so far in an inquiry that initially focused on fund managers and publicly traded companies. Prosecutors have since expanded their investigation to include individuals connected to financial institutions, regulatory agencies, and political circles. The allegations concern possible bribery and market manipulation, although the full extent of the suspected misconduct has not been established.

The exchange's board removed Ergun from his executive responsibilities before the arrest became public. Borsa Istanbul has not yet provided a detailed explanation of the allegations or their potential impact on its operations. Ergun's response to the charges was also unavailable in the initial reporting. His arrest represents a significant development because the investigation now involves the leadership of the institution responsible for operating Turkey's principal stock market.

Fund collapse triggers broader regulatory scrutiny

The inquiry gained momentum after several investment funds suffered sharp declines in September, exposing weaknesses in a market that had attracted substantial retail investment. Nearly 500,000 investors were affected by the turmoil, which also contributed to steep losses in Turkish equities. Investigators are examining whether improper trading practices and relationships between market participants played a role in the collapse.

The investigation has also reached Turkey's settlement and custody infrastructure. Yunus Arinci, chief executive of Istanbul Takas ve Saklama Bankasi, resigned after being questioned over the weekend. Prosecutors separately ordered the detention of four former Capital Markets Board officials, an employee of the banking regulator, and an executive at Tera Holding. The widening scope suggests authorities are examining possible connections between investment firms and institutions responsible for market oversight.

Market confidence faces a fresh test

The arrest creates additional uncertainty for Turkey's financial markets as authorities investigate the events behind September's fund losses. The involvement of senior exchange and regulatory figures raises questions about the effectiveness of existing safeguards, particularly for individual investors who rely on market supervision.

For Borsa Istanbul, the immediate challenge is maintaining normal operations while the investigation continues. Its longer-term implications will depend on whether prosecutors establish coordinated misconduct and how regulators respond. With nearly half a million investors already affected, restoring confidence in fund management, trading practices, and regulatory oversight remains central to the market's recovery.
