Investigation permission against former CMB Chairman Gönül

There has been a new development in the fund investigation carried out by the Istanbul Chief Public Prosecutor's Office.

Following the preliminary examination, Minister of Treasury and Finance Mehmet Şimşek gave permission for an investigation against former Capital Markets Board (CMB) Chairman İbrahim Ömer Gönül.

In a letter sent to the Ministry of Treasury and Finance on September 30, the Istanbul Chief Public Prosecutor's Office requested permission to conduct an investigation against Gönül for "abuse of office".

In the letter of the Chief Public Prosecutor's Office, it was stated that four separate investigations were ongoing regarding allegations that manipulative transactions in some stocks traded on Borsa Istanbul were carried out through investment funds and portfolio management companies.

The prosecutor's office had reported that there were "clear and sufficient indications" that Gönül did not fulfill his duties and responsibilities regarding the supervision of investment funds during his term as CMB Chairman.

Following the request, Minister Şimşek assigned the Inspection Board of the Ministry of Treasury and Finance to conduct a preliminary examination and investigation on October 2.

Former CMB Chairman Gönül testified as a suspect at the Istanbul Chief Public Prosecutor's Office on September 30 within the scope of the fund investigation.

In accordance with Article 133 of the Capital Markets Law No. 6362, the permission of the Minister of Treasury and Finance is required to conduct an investigation against the CMB Chairman and members due to criminal allegations related to their duties.

With the decision made by Şimşek, the way was opened for an investigation against Gönül.

İbrahim Ömer Gönül was appointed as CMB Chairman on April 18, 2022, and left his post after his four-year term ended in April 2026. Gönül was appointed as the President of the Public Oversight, Accounting and Auditing Standards Authority on May 8, 2026.
