MSCI Freezes Amendments to Turkish Equity Indices Over Concerns of Free Float Manipulation

MSCI has frozen certain amendments to its Turkish equity indices, citing serious concerns regarding market integrity as part of its 2026 market classification review.

The organization announced that the decision takes effect immediately and remains in force until further notice. It clarified that its concerns stem from the possibility of coordinated transactions between institutional investors and funds linked to small-cap companies listed on the Istanbul Stock Exchange, which could distort the free float calculations for these securities.

MSCI set three conditions to address these issues: first, provision of detailed and timely information about the ultimate beneficial owners of the companies in question. Second, establishment of effective monitoring and enforcement mechanisms to counter coordinated transactions. Third, adoption of a transparent system based on clear rules for identifying securities with distorted free float ratios.

The organization noted that Turkish authorities have taken some steps following these assessments, but it did not specify the nature of these measures or evaluate their adequacy — a cautious formulation whose implications are unmistakable.
