MSCI has suspended certain changes to its Turkey equity indexes, raising concerns over market transparency and warning that the country could lose its emerging-market status if regulatory improvements are not achieved by mid-2027.
The global index provider announced the decision on Thursday, October 15, citing concerns about free-float calculations and potentially coordinated trading involving smaller publicly listed Turkish companies. The restrictions took effect immediately and will remain in place until further notice.
Although Turkey will retain its classification as an emerging market for now, MSCI warned that insufficient reforms could lead to a downgrade to frontier- or standalone-market status. Such a move could prompt significant selling by investment funds tracking the MSCI Emerging Markets Index.
The decision follows concerns identified during MSCI's 2026 Market Classification Review, particularly allegations of coordinated trading through investment funds closely connected to certain smaller listed companies.
MSCI emphasized that institutional investors require stronger regulatory enforcement, greater transparency, and reliable disclosure standards to independently verify the free float of Turkish securities.
Under the suspension, MSCI will not increase foreign inclusion factors or index share counts for Turkish securities. It will also prevent new additions to the MSCI Turkey Investable Market Index and block upward movements between market capitalization segments.
Turkey's stock market already faces challenges due to the limited number of companies meeting international institutional investors' liquidity and market capitalization requirements. This concentration has intensified concerns about trading practices and the accuracy of publicly available share data.
Meanwhile, the benchmark BIST 100 index has experienced sustained selling pressure. The index closed at 12,070.17 on October 15, declining 0.40%, and is heading toward its fifth consecutive weekly loss. It has also fallen more than 20% from its record closing high in May.
MSCI said it would continue monitoring Turkish regulatory developments and gathering feedback from market participants. If meaningful improvements are not demonstrated by June 2027, the index provider could initiate consultations on reclassifying Turkey's equity market.
The warning follows a similar assessment by S&P Dow Jones Indices in July, when the company identified market transparency concerns that could threaten Turkey's emerging-market classification.
Both warnings highlight growing pressure on Turkish regulators to strengthen investor protections, improve market integrity, and restore international investor confidence.
