The BIST 100 index lost 5.54% that same day and hit a circuit breaker; the selling soon spread to Tera Portföy funds as well. It became apparent that the problem was not confined to those two firms but also extended to Hedef, Atlas, A1 Capital, Pardus and Bulls Portföy.

Borsa Istanbul’s BIST 100 index came under significant selling pressure over three consecutive trading sessions between 15-17 September 2026. The index closed down 5.54% on 16 September, a move that triggered Borsa Istanbul’s index-linked circuit breaker, and negative momentum continued into the morning of 17 September. The sell-off was primarily triggered by a default at Pusula Portföy Yönetimi A.Ş., a portfolio management company, which failed to meet investor redemption requests from certain funds it manages in a timely manner. A similar liquidity problem emerged at Tera Portföy Yönetimi A.Ş., and this situation put pronounced pressure on the shares of both companies as well as on broader market indices.
