MSCI freezes Turkey index changes, ties classification review to progress by 2027
Key Facts
MSCI announced on 15 October 2026 a freeze on specific changes to its Turkish equity indexes amid concerns over the reliability of free-float estimates and market integrity. The company said the decision takes effect immediately and until further notice, halting increases in foreign inclusion factors and the share counts used in its indexes. The decision also suspends additions to the Turkey Investable Market Index and upgrades of existing securities to higher size segments. The concerns centre on potential coordinated trading through funds linked to small listed companies and the impact of those links on free-float calculations. The measure leaves Turkey's emerging-market classification unchanged, according to Reuters, while the company has tied consideration of classification measures to progress in addressing the concerns.
The freeze broadens the treatment MSCI announced in July, when it was assessing Turkish stocks on a case-by-case basis as investability concerns arose. Its earlier warning linked the potential launch of a consultation on the appropriate treatment of Turkey and its eligible securities to a lack of sufficient progress by the November 2026 review. The MSCI Turkey Index measures the performance of large and mid-cap companies and covers about 85% of the Turkish equity universe, according to the company's description of the index. As background to the investability concerns, Reuters pointed to the small number of Turkish stocks meeting global institutional investors' size and liquidity requirements. The agency said this concentrates capital in a limited number of companies.
In its market classification review, MSCI said international institutional investors had reported recurring instances of potential coordinated trading through funds linked to some small listed companies. It added that these potential practices lead to "artificially inflated free-float estimates". Investors called for detailed and timely disclosure of beneficial ownership, according to the company's account in the review. Their demands also included strong oversight and effective enforcement against coordinated trading, alongside measures to address problems with free-float calculations. They also called for a transparent, rules-based framework for handling securities with structural distortions in their free float.
In response to ownership concerns, Turkey's Capital Markets Board introduced a framework to exclude fund-held stakes from free-float calculations, according to MSCI. The exclusion applies when the beneficial owners of those stakes are parties already excluded from the calculation. On trading restrictions, the company's market accessibility report said Borsa Istanbul reinstated a blanket short-selling ban on 2 March 2026. Separately, in the context of the fund crisis, Investing cited Bloomberg in September as reporting that funds ordered to liquidate held investments exceeding $18 billion. Those funds had about 350000 investors, according to the same report.
Concerns over market transparency extended to other index providers, with S&P Dow Jones Indices also warning in July of a possible reclassification of Turkey from an emerging market to a frontier market. The provider attributed its warning to market transparency and other concerns, according to Reuters. In reaction to the freeze, EL7 coverage recorded a decline of more than 3% in Turkish stocks on 16 October 2026 following the announcement of the measure. Reuters said a subsequent downgrade of Turkey to frontier-market status could trigger selling by funds tracking the MSCI Emerging Markets Index. Such potential selling remains contingent on a subsequent downgrade, while the latest freeze left Turkey's emerging-market status intact.
The next assessment is set for June 2027, when MSCI will consider whether sufficient progress has been made in addressing concerns over the Turkish market. The company said it would reassess Turkey's treatment as part of its annual market classification review. If sufficient progress is not evident by then, it may consider measures including a consultation on reclassifying Turkey as a frontier or standalone market. It said in its statement that "additional time is needed to assess whether these measures deliver the structural improvements investors are seeking". It added that it would continue to seek feedback from market participants as it assesses the results of the Turkish measures.
