Borsa Istanbul will replace more than one quarter of the companies in its benchmark BIST-100 index, marking the exchange’s largest reshuffle in six years.

The changes follow a sharp market sell-off linked to liquidity problems at investment funds holding thinly traded shares. Redemptions forced some funds to sell more liquid assets, increasing pressure on the wider market.

Turkish authorities intervened with additional central-bank funding, temporary changes to margin requirements and orders affecting 131 funds with hundreds of thousands of investors.

Destek Finans and Katılımevim are among the companies due to leave the BIST-100, while Anadolu Grubu Holding and TAB Gıda will return to the benchmark.

Destek Finans will also be removed from the BIST-30. The index changes are expected to become effective next month as regulators seek to strengthen trading quality and investor confidence.

Revised inclusion rules require companies to meet new conditions related to share-price volatility and equity size before qualifying for the Star Market, which is necessary for membership in the leading indices.

Analysts welcomed the tighter standards as a step toward healthier price formation, although the episode has renewed debate about limited liquidity, market concentration and transparency in Turkish equities.
