  • • New regulations restrict hedge funds' exposure to related parties and impose stricter requirements on concentrated investments across portfolio holdings.
  • • Hedge funds must achieve full compliance with the new regulatory framework by the end of 2026, with mandates to reduce excess positions that exceed the newly established thresholds.
  • • The regulatory tightening reflects a broader regulatory focus on transparency, risk management, and investor protection as the alternative investment sector continues to expand in Turkey's capital markets.
Summary
Turkey's capital markets regulator has implemented comprehensive new restrictions on hedge fund operations, introducing quantitative limits on concentrated equity positions and related-party exposure. The centerpiece of the regulatory overhaul establishes position limits on holdings of an issuer's free-floating shares, with caps ranging from 2% to 8% depending on the size of the company's freely traded equity base. These tiered restrictions are designed to prevent excessive concentration in individual securities and reduce the potential for market manipulation through coordinated or outsized positioning.

The regulatory framework extends beyond simple position limits to address systemic risks associated with related-party exposure. Hedge funds now face enhanced disclosure and limitation requirements regarding transactions or holdings involving affiliated counterparties, subsidiaries, or related entities. This component of the reform targets potential conflicts of interest and information asymmetries that could disadvantage other market participants or destabilize pricing mechanisms.

Compliance with the new ruleset carries a definitive deadline of December 31, 2026, providing hedge funds with a transition period to restructure portfolios and operational frameworks. Firms that currently maintain positions exceeding the newly established thresholds are required to reduce excess holdings within this timeline. The staggered implementation approach acknowledges the operational complexity of unwinding concentrated positions while maintaining market stability.

The regulatory initiative reflects Turkey's broader commitment to enhancing market microstructure safeguards and protecting retail investors as alternative investments gain prominence in the domestic capital markets. By establishing transparent, rules-based position limits and enforcing related-party disclosures, the regulator aims to create a more level playing field for institutional and retail participants while maintaining the competitiveness and depth of Turkey's hedge fund ecosystem.
