Turkish authorities have detained five people, including the chairs of two funds at the center of an investigation launched after some investment funds defaulted on redemption requests, the ⁠Justice Ministry said on ⁠Saturday.

Authorities intervened this week to shore up market stability after a ​liquidity crunch at investment ​funds triggered a sell-off in the country's benchmark stock index. The measures helped the index recover some of its losses.

As part of the intervention, the Capital Markets Board (SPK) also mandated lenders Işbank and Ziraat Bank to oversee the liquidation of 131 investment funds managed by seven portfolio management companies, ⁠including ⁠Tera Portföy, Pusula Portföy and Hedef Portföy, on the TEFAS electronic fund platform.

The ministry said in a statement that Pusula Holding Chair Serdar Turhan, Tera Yatırım Holding Chair Emre Tezmen and three fund administrators had been detained ⁠as part of the investigation.

It said four other suspects had already been arrested and all other ​suspects identified by the Capital Markets Board ​had been barred from leaving the country and had their assets frozen.

Treasury and Finance ⁠Minister ‌Mehmet ‌Şimşek said on Friday that ⁠the liquidation of investment ‌funds worth $18.3 billion would not put pressure on ​Borsa Istanbul because ⁠regulatory changes should prevent any ⁠contagion risk.

He said authorities would ⁠continue to monitor ​the market closely.
