Turkey aims to finish new market abuse law by early 2027

Turkey plans to adopt new rules aimed at preventing coordinated trading and other capital-market crimes by early 2027, according to Finance Minister Mehmet Şimşek. The announcement coincides with Vice President Cevdet Yılmaz’s statement that a comprehensive reform bill is under preparation. The drive follows a recent fund turmoil in which the Capital Markets Board halted trading in 131 funds, placed them into liquidation and saw over 80 arrests of senior asset-management officials.

The government is targeting the liquidation of half the troubled funds this week and has introduced a Fund Guide requiring weekly portfolio disclosures and concentration limits. MSCI responded to the crisis by freezing adjustments to its Turkey equity indexes and warned that insufficient progress by June 2027 could trigger a downgrade to frontier-market status. Şimşek emphasized that sanctions will be applied to anyone undermining market fairness, while Yılmaz said the upcoming legislation will strengthen market structure and protect investors.
