Borsa İstanbul’s Circuit Breaker: Short-Term Market Pause

At Borsa İstanbul, the circuit‑breaker mechanism was triggered when the BIST 100 index breached predetermined threshold levels. This automated system is designed to curb excessive volatility by halting trading instantly once a specified decline rate is reached. During the circuit‑breaker period, all buy‑sell transactions on the exchange were temporarily suspended. The duration of the pause is set according to Borsa İstanbul’s rules and typically ranges from a few minutes to an hour. Throughout this interval, investors had the opportunity to monitor market data and assess the situation. Once the pause ended, Borsa İstanbul resumed operations and the trading floor became active again. The brief halt was viewed as an important signal for risk management by market participants. This is not investment advice.
