BIST 100 closes down 5.54% at 13,122.58, wiping ₺1.32 trillion off Borsa İstanbul as circuit breaker halts trading; asset manager Pusula Portföy failed to meet ₺55bn in redemptions

Borsa İstanbul's BIST 100 index closed 16 September 2026 down 5.54% at 13,122.58 points, its lowest level in about 5.5 months, with roughly ₺1.3 trillion wiped off the value of Turkey's stock market in the selloff and the exchange's circuit breaker triggered, temporarily halting trading. The slump is attributed to Turkish asset manager Pusula Portföy failing to meet ₺55 billion in investor redemption requests sitting on illiquid names, with the firm's disclosure that payments could not be made on time and a default statement deepening fears of a broader liquidity crisis across the country's fund industry; investors have pulled about $1 billion from funds in what has been described as a "fund run".
