What Is the Concept of “Circuit Breaking” as Applied to Index Price Deviation?

Circuit breaking in this context refers to an exchange mechanism that is triggered when the derivative's trading price deviates excessively from the underlying Index Price. When the deviation threshold is breached, the mechanism may halt trading, adjust price limits, or impose other restrictions.

This prevents the derivative from trading at an unsustainable premium or discount to its fair value, protecting traders from extreme market volatility.
