Why do financial markets have circuit limits?

Ever wondered why circuits are in place? 

It all started on Black Monday in 1987, where a 25% market correction prompted the introduction of market-wide circuit breakers in the US. These limits aimed to ensure market maker solvency and prevent panic-induced trading.

Fast forward to 2001, and India also introduced circuits to handle intraday market volatility. From the Nifty's inception to the imposition of index-level circuit filters, the Indian market landscape has witnessed a steady evolution in its approach to market regulation.

In this episode, we delve deeper into the concept of circuits, with real life stories and understand how they help the market. 

We also discuss, should circuits continue to exist in their current form? or is it time to explore alternatives that foster greater transparency and resilience?
