Circuit Breaker History
Storyโ The year 2020 dawned with promise but quickly turned into a nightmare as the COVID-19 pandemic spread globally. On March 12, Indian markets opened to massive selling pressure, triggering the 10% circuit breaker within minutes. Trading halted for the entire day, leaving many traders stunned but preventing a complete market collapse. This event became a chapter in market history, demonstrating both the necessity and limitations of circuit breakers.
In the great market crash of 2000, traders witnessed the Sensex plummet like a wounded bird, leading to the creation of circuit breakers as protective shields. These mechanisms became legendary guardians of market stability, tested during the COVID-19 storm when they activated within minutes of opening.

Lesson Content
Circuit breakers are crucial market safety mechanisms designed to prevent panic selling and market crashes. In India, the concept was introduced after the 2000-2001 tech crash when the BSE Sensex lost nearly 50% of its value. The Securities and Exchange Board of India (SEBI) implemented circuit breakers in 2001 to halt trading during extreme volatility. These mechanisms trigger automatic trading halts when markets move beyond certain thresholds - 10%, 15%, and 20% for indices. The most notable instance was on March 12, 2020, when the circuit breaker was activated within minutes of market opening due to COVID-19 panic. This halted trading for the entire day, preventing further freefall. Historically, global markets like the US also implemented circuit breakers after the 1987 Black Monday crash. The Indian market has since refined these mechanisms, with different rules for futures and options segments. Understanding circuit breakers is essential for traders as they directly impact market liquidity and execution during volatile periods.
