A Turkish court has ordered the pre-trial detention of former Family and Social Services Minister Fatma Betül Sayan Kaya over an expanding investigation into alleged stock market manipulation and irregularities involving investment funds worth billions of dollars.
Kaya was remanded in custody on Friday, November 6, 2026, following questioning by prosecutors in Istanbul, according to Turkey’s state-run Anadolu Agency and international media reports.
The former minister faces accusations of violating capital markets legislation and belonging to an organisation allegedly established to commit crimes. The charges form part of a wider investigation into suspicious financial transactions that have shaken confidence in Turkey’s investment market and affected hundreds of thousands of investors.
Kaya, who served in President Recep Tayyip Erdoğan’s government between 2016 and 2018, previously held a senior position in the ruling Justice and Development Party (AK Party).
Her detention represents another significant development in an investigation that has increasingly drawn in prominent political figures, financial executives and officials connected to Turkey’s financial regulatory institutions.
Authorities have not established Kaya’s guilt, and the accusations against her remain subject to judicial proceedings.
Allegations Against the Former Minister
Prosecutors are investigating financial transactions involving Kaya and her husband, İlyas Kaya, particularly their investments in shares of Özata Denizcilik, a Turkish shipbuilding company.
According to figures reported by Reuters, the couple allegedly invested approximately 163 million Turkish lira in financial assets and subsequently received about 2.17 billion lira from investment sales.
The transactions reportedly generated substantial returns within a period of approximately four months, attracting scrutiny after the country’s investment fund crisis emerged in September.
The allegations include claims that Kaya possessed undisclosed information capable of influencing the prices of financial instruments or investment decisions.
Investigators have also examined her reported contacts with Emre Tezmen, a former executive associated with Tera Group, one of the financial institutions at the centre of the wider investigation.
The prosecution has questioned the timing and structure of the transactions, including the circumstances surrounding the transfer and payment for shares shortly before the regulatory intervention in the investment fund industry.
These issues form part of the prosecution’s case and have not yet been established as criminal conduct by a final court judgment.
How the Investment Fund Scandal Developed
The investigation began following a financial crisis in September 2026, when several Turkish investment funds encountered difficulties meeting investors’ withdrawal requests.
The crisis raised concerns about alleged manipulation of shares in companies with relatively limited trading activity. Investigators suspect that certain fund managers and financial market participants used coordinated transactions to inflate share prices and generate profits before the market experienced a sharp decline.
One company that attracted particular attention was Özata Denizcilik.
According to Reuters, the company’s shares rose from approximately 220 lira at the beginning of April to 4,980 lira on September 15, before suspected market manipulation triggered a liquidity crisis and a wider market sell-off the following day.
The sudden movement in share prices intensified questions about how the funds had been managed and whether some investors had benefited from information unavailable to ordinary market participants.
Turkey’s Capital Markets Board subsequently ordered the liquidation of 131 investment funds managed by seven companies as authorities sought to contain the financial fallout.
The liquidation process was intended to help recover and distribute assets to affected investors, although the process raised concerns about how quickly investors could regain access to their money.
More Than 455,000 Investors Caught Up in the Crisis
The investment fund scandal has become a major concern for Turkey’s financial sector because of the number of people and the volume of money involved.
Reports indicate that more than 455,000 investors were affected by the liquidation of the 131 funds.
The combined assets involved were estimated at approximately 936.3 billion Turkish lira, equivalent to around $19.1 billion at the time of the reported valuation.
The crisis has raised questions about investment management, financial supervision and the ability of regulators to identify suspicious trading activities before they threaten market stability.
For individual investors, the consequences extend beyond fluctuations in share prices. Delays in accessing savings can affect household finances, business operations and confidence in financial institutions.
The scale of the investigation also suggests that authorities are examining more than isolated investment decisions, with attention extending to relationships between fund managers, financial companies and regulatory officials.
Former Minister’s Husband Released Under Judicial Measures
Kaya’s husband, İlyas Kaya, was also questioned as part of the investigation but was released under judicial measures.
Reuters reported that he was barred from travelling abroad while the investigation continued.
The couple have denied wrongdoing, according to the Associated Press.
Media reports also indicate that some of the investment gains were transferred into an account designated by banking regulators as part of arrangements for returning disputed proceeds.
However, the transfer of funds does not by itself establish criminal liability or resolve the allegations against the couple.
The investigation is continuing as prosecutors examine the transactions and relationships involving individuals suspected of participating in the alleged financial misconduct.
Investigation Expands to Political and Financial Institutions
Kaya’s detention is part of a much wider investigation that has reached senior figures in Turkey’s financial sector.
On November 3, Justice Minister Akin Gurlek said investigators were examining what he described as a broad criminal network operating within the country’s financial markets.
According to figures he provided, 433 people were under investigation, with 112 suspects remanded in custody, 186 placed under judicial control and 38 others being sought by authorities.
The investigation has also involved senior figures associated with Borsa Istanbul, the country’s principal stock exchange, and the Capital Markets Board.
Korkmaz Enes Ergun, the former head of Borsa Istanbul, was detained on October 31 over suspected bribery and membership of an organisation allegedly established to commit crimes. His case forms part of the broader investigation into suspected financial irregularities.
Former officials connected to financial regulation have also faced scrutiny over their responsibilities in supervising investment funds and monitoring market activities.
The developments have increased pressure on Turkey’s financial institutions to explain how the alleged manipulation occurred and whether regulatory weaknesses allowed suspicious transactions to continue.
President Recep Tayyip Erdoğan has also pledged that those found responsible for manipulating financial markets would be held accountable.
According to Euronews’ November 3 report, the government has made the recovery of funds obtained through alleged market manipulation a central priority.
The authorities have also pursued the freezing of assets and bank accounts linked to people and organisations under investigation.
Government Moves to Recover Investors’ Money
Beyond the criminal investigation, the Turkish government faces the challenge of restoring confidence among investors affected by the fund crisis.
The liquidation of 131 investment funds has created pressure on regulators and financial institutions to establish how much money can be recovered and how quickly it can be returned to investors.
Euronews reported on November 3 that Justice Minister Gurlek said approximately 30 billion lira in cash, real estate and shares had been recovered through the government’s efforts.
The Turkish presidency also reported that payments totalling 97.3 billion lira had been made to nearly 250,000 investors by October 30.
These figures indicate that efforts to compensate affected investors are continuing, although they do not establish that all investors have recovered their money.
The government has also sought to recover assets allegedly transferred outside Turkey, according to the justice minister’s public comments.
The wider investigation is therefore pursuing two connected objectives: establishing criminal responsibility and recovering funds that may have been obtained through unlawful market activities.
Why the Investigation Matters for Turkey’s Economy
The scandal presents a significant challenge to Turkey’s financial market, particularly at a time when authorities are seeking to maintain investor confidence and attract capital.
Investment funds play an important role in connecting individual savings with businesses, securities and other financial assets. Their credibility depends on transparent management, effective regulation and confidence that investors are operating under fair market conditions.
Allegations that market participants manipulated share prices or benefited from undisclosed information could undermine that confidence.
The involvement of former political officials and senior financial executives also raises questions about institutional accountability and the independence and effectiveness of financial oversight.
For international investors, the investigation could influence perceptions of Turkey’s regulatory environment and the risks associated with investing in its capital markets.
However, the allegations must be distinguished from proven wrongdoing. The investigation has not established that every person questioned or detained participated in the alleged scheme.
What Happens Next?
Kaya is expected to remain in pre-trial detention as judicial proceedings continue.
Prosecutors are expected to pursue further investigations into the transactions, financial relationships and alleged connections between individuals and companies involved in the fund crisis.
Authorities are also continuing efforts to identify and recover assets connected to suspected market manipulation.
The outcome of the proceedings will be important in determining the extent of individual responsibility and whether the allegations against Kaya and other suspects can be established in court.
For investors affected by the crisis, the immediate concern remains the recovery of their money and the restoration of confidence in Turkey’s financial system.
The investigation is likely to remain under close scrutiny as authorities pursue additional suspects and work to establish how the alleged financial network operated.
Weng Global will continue to follow developments in the investigation and its implications for Turkey’s financial markets.
