Key Takeaways
- • Turkey's Capital Markets Board (CMB) has imposed issuer-level concentration limits on hedge funds, restricting holdings to between 2% and 8% of an issuer's free-floating shares depending on stock liquidity, effective immediately with a phased compliance timeline through end-2026.
- • Hedge funds are now prohibited from allocating more than 20% of portfolio assets to securities issued by affiliated companies under management control, closing a regulatory gap that previously exempted hedge funds from equity fund concentration restrictions.
- • Positions individually exceeding 5% of fund assets cannot collectively exceed 20% of total portfolio value, with non-compliant funds required to reduce excess holdings by one-third by October 31, two-thirds by November 30, and achieve full compliance by December 31, 2026.
- • The regulatory tightening responds to market manipulation concerns and scrutiny over unusually large gains in individual stocks and investment funds, suggesting potential price distortion through related-party trading or coordinated account activity in illiquid equity segments.
- • These rules represent a significant regulatory escalation as previous concentration limits applied only to equity-heavy funds, leaving hedge funds subject to less stringent oversight despite their growing influence over thinly-traded Turkish equities.
Summary
Turkey's Capital Markets Board has introduced comprehensive new restrictions on hedge fund investment concentration, marking a significant regulatory shift aimed at addressing market manipulation risks and protecting equity market integrity. The amended guidelines impose issuer-level limits that restrict hedge fund exposure to any single company's freely traded shares to between 2% and 8%, calibrated based on the company's free-float ratio. This tiered approach reflects market realities where liquidity varies substantially across Turkish equities.
The regulatory framework also establishes a portfolio-level affiliated entity restriction, prohibiting hedge funds from allocating more than 20% of assets to securities issued by companies under their management's control. Additionally, any single position representing more than 5% of a fund's assets cannot be combined with other similarly sized positions to exceed 20% of total portfolio value collectively. These layered restrictions target both direct concentration risk and potential conflicts of interest arising from related-party control.
The CMB has established a phased compliance timeline for existing positions exceeding the new thresholds. Funds must reduce excess holdings by at least one-third by October 31, 2026, by two-thirds by November 30, 2026, and achieve full compliance by December 31, 2026. This graduated approach provides liquidity relief while ensuring timely market adjustment.
The regulatory action reflects mounting concerns over market manipulation in Turkey's equity markets, where certain investment funds have accumulated disproportionate influence over illiquid stock trading. Unusually strong returns in individual securities and funds have raised regulatory questions about whether coordinated trading or related-account activity may be artificially inflating valuations. Prior restrictions on concentrated equity positions applied primarily to equity-heavy funds, leaving hedge funds operating under less stringent oversight despite their material market impact. These new rules eliminate that regulatory arbitrage and bring hedge funds into alignment with broader institutional investor concentration standards.
