Turkish financial market volatility and investment trends

Overview

Turkish financial markets have experienced a period of volatility and shifting investment patterns. In late September 2026, the BIST 100 index saw a decline of 2.74%, driven by losses in banking and holding company shares, while the Turkish Lira weakened against the US Dollar, Euro, and British Pound. During this period, index providers MSCI and FTSE Russell raised concerns regarding the transparency of partnership structures and discrepancies in reported free float data. Experts warned that potential re-evaluations by these providers could trigger automated fund selling and significant capital outflows.

By October 2026, foreign investment trends showed mixed results. While Borsa İstanbul recorded a net foreign inflow of $356.2 million in September, dollar-denominated investment fund portfolios held by foreign investors saw a sharp contraction, falling from $11.1 billion in August to $5 billion in September. In mid-October, MSCI announced an immediate freeze on specific changes to its Turkey equity indexes, including increases to Foreign Inclusion Factors (FIF), the number of shares (NOS) used in index calculations, the addition of new securities to the MSCI Turkey Investable Market Index (IMI), and the upward migration of stocks into larger size-segment indexes. This decision follows concerns regarding potential coordinated trading through fund holdings that could undermine market integrity and the reliability of free-float estimates.

MSCI warned that it will reassess Turkey’s emerging-market status during its 2027 annual review, noting that a downgrade to frontier or standalone status could be considered if progress in transparency and enforcement is not demonstrated by June 2027. Following these developments, the BIST 100 index faced significant selling pressure. During the week of October 12–16, 2026, the index closed with a 4.44% loss at 11,721.72 points. Notable decliners during this week included 1000 Yatırımlar Holding (BINHO), which dropped 26.32%, and Tekfen Holding (TKFEN), which fell 23.77%.
