Mahmut Sutcu stepped down on Monday from his role leading Turkey's financial markets regulator, pointing to health issues. Sutcu took charge of the Capital Markets Board in May, after working as a deputy under former chief Ibrahim Omer Gonul. His departure comes as domestic financial markets contend with widespread disruption triggered by trouble at several major investment vehicles.

The leadership change occurs amid an intensifying government probe into high-yield funds. Tensions escalated in September when these funds stopped honoring cash withdrawal requests, driving an extensive exit by investors. Officials and market participants are examining whether watchdog agency oversight was insufficient, particularly regarding trading activities that the justice minister referred to as "Ponzi-like."

Law enforcement agencies have broadened their inquiries to encompass both regulatory supervision and fund operations. Authorities have held multiple asset management leaders prior to trial, with Tera Portfoy Yonetimi AS and Pusula Portfoy Yonetimi AS among the affected firms. Former regulator Gonul is also facing scrutiny over whether his team missed early warning signs regarding unusually steep returns before the September redemption freeze.
